chore: prepare the 3.7.0 release (#673)

Bumps src.__version__ to 3.7.0 and turns Unreleased (#672: sports_celebration,
sports_fetch and sports_card_wrappers) into ## 3.7.0; src/common/README.md and
docs/SPORTS_UNIFICATION.md say 3.7.0 for the three modules.

+- Link a plugin for development: `./scripts/dev/dev_plugin_setup.sh link-github <name>` clones the `ledmatrix-plugins` monorepo into `~/.ledmatrix-dev-plugins/` and links its `plugins/<name>` under the manifest id (add a repo URL for a plugin with its own repo; or `link <name> <path>`); symlinks land in `plugins/` — set `plugin_system.plugins_directory` to `plugins` so discovery picks them up. Fork/location overrides: `dev_plugins.json` (from `dev_plugins.json.example`)
 - Browser preview without the display loop: `python3 scripts/dev_server.py` → http://localhost:5001
 - Full display in emulator mode: `python3 run.py -e` (or `EMULATOR=true python3 run.py`)
 - Validate one plugin headlessly: `python3 scripts/check_plugin.py --plugin <id>`
+- Soak a rig for frame timing (on the Pi, service running): `python3 scripts/frame_soak.py --preview` — late-frame rate across every scroller; see `docs/SCROLL_PERFORMANCE.md`
 
 ## Plugin Store Architecture
 - Official plugins live in the `ledmatrix-plugins` monorepo (not individual repos)
 - Plugin repo naming convention: `ledmatrix-<plugin-id>` (e.g., `ledmatrix-football-scoreboard`)
 - `plugins.json` registry at `https://raw.githubusercontent.com/ChuckBuilds/ledmatrix-plugins/main/plugins.json`
-- Store manager (`src/plugin_system/store_manager.py`) handles install/update/uninstall
-- Monorepo plugins are installed via ZIP extraction (no `.git` directory)
+- Store manager (`PluginStoreManager` in `src/plugin_system/store_manager.py`) handles install/update/uninstall
+- Monorepo plugins are installed without a `.git` directory: GitHub Trees API + raw downloads, falling back to ZIP extraction
 - Update detection for monorepo plugins uses version comparison (manifest version vs registry latest_version)
 - Plugin configs stored in `config/config.json`, NOT in plugin directories — safe across reinstalls
 - Third-party plugins can use their own repo URL with empty `plugin_path`
 
-## Skin System (visual overlays for sports scoreboards) — NOT SUPPORTED YET
-- Skins do not render with the current scoreboard plugins: the only hook is `SportsCore._render_game()` in `src/base_classes/sports/core.py`, and no current scoreboard plugin (monorepo or third-party registry) builds on `src.base_classes`
-- So core doesn't offer them: no Visual Skin dropdown (`get_plugin_schema` skips `inject_skin_selector`), the store hides/refuses `"type": "skin"` entries, `GET /api/v3/skins` reports `"supported": false`. Switch: `SKINS_RENDER_SUPPORTED` in `src/skin_system/__init__.py`
-- Stored `skin` / `skin_options` config values must keep loading and saving (base schema allows them; form saves deep-merge over the stored section)
-- Skins live in `skins/<skin-id>/` (skin.json + skin.py), NOT in plugin dirs — plugin reinstall deletes plugin dirs
-- Core: `src/skin_system/` (ScoreboardSkin, SkinContext, runtime); keep it and its tests
-- Skins render onto `ctx.canvas` only; fallback to built-in renderer on `False`/exception (3 strikes disables for session)
-- View-model guaranteed keys are frozen (see `test/test_skin_system.py::TestViewModelContract`) — renaming keys in `_extract_game_details_common` or sport extractors breaks published skins
-- Validate skins headlessly: `python scripts/validate_skin.py --skin <id>`; docs: `docs/SKIN_SYSTEM.md`, `docs/CREATING_SKINS.md`
-- Skins are NOT monorepo plugins: no manifest bump / update_registry.py needed
-
 ## Common Pitfalls
-- paho-mqtt 2.x needs `callback_api_version=mqtt.CallbackAPIVersion.VERSION1` for v1 compat
+- paho-mqtt 2.x requires a `CallbackAPIVersion` argument: `VERSION1` for code written against v1 callback signatures (the MQTT bridge uses `VERSION2`)
 - BasePlugin uses `get_logger()` from `src.logging_config`, not standard `logging.getLogger()`
 - `DisplayManager` has no `draw_image()` — paste onto the PIL image directly:
   `self.display_manager.image.paste(img, (x, y))` then `update_display()`
   (use a mask for transparency: `image.paste(rgba, (x, y), rgba)`)
 - When modifying a plugin in the monorepo, you MUST bump `version` in its `manifest.json` and run `python update_registry.py` — otherwise users won't receive the update
+- `src/pi5_matrix_support.py` hardcodes what the pinned `rpi-rgb-led-matrix-master` can drive on a Raspberry Pi 5 (`Rp1PioConfigSupported()` in `lib/rp1/rp1_pio_backend.cc`). Re-check it whenever the submodule is bumped: a stale rule blocks Pi 5 settings the new library supports, and a missing one lets the display service crash-loop. `src/matrix_support.py` holds the same kind of rules for every board (rows, chain length, mapping names, parallel per mapping) and needs the same re-check

 #### PWM (Pulse Width Modulation) Settings
 
 These settings affect color fidelity and smoothness of color transitions:
 
-- **`pwm_bits`** (integer, default: 9)
-  - Number of bits used for PWM (affects color depth)
-  - Higher values (9-11) = more color levels, smoother gradients
-  - Lower values (7-8) = fewer color levels, but may improve stability on some hardware
-  - Range: 1-11, recommended: 9-10
+- **`pwm_bits`** (integer, 1-11, default: 9)
+  - Color depth per channel: how many brightness levels each LED gets
+  - Higher values (9-11) = more color levels, smoother gradients, lower refresh rate
+  - Lower values (7-8) = the subtlest shades are dropped for a higher refresh rate; `1` gives 8 colors
+  - Recommended: 9-10
 
-- **`pwm_dither_bits`** (integer, default: 1)
-  - Additional dithering bits for smoother color transitions
-  - Helps reduce color banding in gradients
-  - Higher values (1-2) = smoother gradients but may impact performance
-  - Range: 0-2, recommended: 1
+- **`pwm_dither_bits`** (integer, 0-2, default: 1)
+  - Time-dithers the lowest color bits: their brightness comes from showing them on only some frames
+  - Raises the refresh rate; the cost is that dark shades can shimmer slightly
+  - `0` = steadiest dim colors, `2` = fastest
+  - The rgbmatrix library accepts only 0-2; a higher value stops the display starting
 
-- **`pwm_lsb_nanoseconds`** (integer, default: 130)
-  - Least significant bit timing in nanoseconds
-  - Controls the base timing for PWM signals
-  - Lower values = faster PWM, higher values = slower PWM
+- **`pwm_lsb_nanoseconds`** (integer, 50-3000, default: 130)
+  - On-time of the least significant color bit; each higher bit doubles it
+  - Lower values = higher refresh rate, but can cost color accuracy or add ghosting on some panels
+  - Higher values = less ghosting (faint trails behind bright text on black), lower refresh rate
   - Typical range: 100-300 nanoseconds
-  - May need adjustment if you see flickering or color issues
 
 #### Advanced Hardware Settings
 
-- **`scan_mode`** (integer, default: 0)
-  - Panel scan mode (how rows are addressed)
-  - Common values: 0 (progressive), 1 (interlaced)
-  - Most panels use 0, but some require 1
-  - Check your panel datasheet if colors appear incorrect
+- **`scan_mode`** (integer, 0-1, default: 0)
+  - Order the rows are refreshed in: `0` = progressive, `1` = interlaced
+  - Interlaced can look a little smoother when the refresh rate is very low, but usually shows a comb effect on anything moving
+  - Leave at `0` unless you are tuning a slow setup
 
 - **`limit_refresh_rate_hz`** (integer, default: 100)
-  - Maximum refresh rate in Hz (frames per second)
-  - Caps the refresh rate for better stability
-  - Lower values (60-80) = more stable, less CPU usage
-  - Higher values (100-120) = smoother animations, more CPU usage
-  - Recommended: 80-100 for most setups
+  - Caps the panel refresh rate in Hz; `0` = no cap
+  - A steady cap reduces flicker caused by other activity on the Pi, and in camera recordings
+  - Scroll speeds are worked out against this value (against 100 Hz when it is `0`), so a cap the panel can actually hold keeps scrolling even
+  - Recommended: 80-120. `sudo python3 scripts/scroll_speeds.py --measure` reports the rate your panel really achieves
 
 - **`disable_hardware_pulsing`** (boolean, default: false)
-  - Disables hardware pulsing (usually leave as false)
-  - Set to `true` only if you experience timing issues
-  - Most users should leave this as `false`
+  - `false` = the Pi's hardware PWM times each brightness pulse; `true` = software timing

+  - Hardware pulsing needs the panel's OE line on GPIO 18 (`adafruit-hat-pwm`, `regular`, the Adafruit Triple LED Matrix Bonnet). With `adafruit-hat` the library uses software timing anyway
+  - It also needs the Pi's onboard sound driver (`snd_bcm2835`) disabled, which `first_time_install.sh` does. Set `true` only if you need the Pi's own audio

 ### Runtime Configuration (`display.runtime`)
 
 These settings control runtime behavior and GPIO timing:
 
 - **`gpio_slowdown`** (integer, default: 3)
-  - GPIO timing slowdown factor
-  - **Critical setting**: Must match your Raspberry Pi model for stability
-  - **Raspberry Pi 3**: Use 3
-  - **Raspberry Pi 4**: Use 4
-  - **Raspberry Pi 5**: Use 1–2 in PIO mode (`rp1_rio: 0`, the default); start with `1` and increase if you see flickering
-  - **Raspberry Pi Zero/1**: Use 1-2
-  - Incorrect values can cause display corruption, flickering, or system instability
+  - GPIO timing slowdown factor (0-10): slows GPIO writes so the panel electronics keep up. Higher is more reliable but lowers the refresh rate

 ## Using Weather Icons
 
-The Display Manager provides built-in weather icon drawing methods for easy visual representation of weather conditions.
-
-### Basic Weather Icon Usage
-
-```python
-def display(self, force_clear=False):
-    if force_clear:
-        self.display_manager.clear()
-    
-    # Draw weather icon based on condition
-    condition = self.data.get('condition', 'clear')
-    self.display_manager.draw_weather_icon(condition, x=5, y=5, size=16)
-    
-    # Draw temperature next to icon
-    temp = self.data.get('temp', 72)
-    self.display_manager.draw_text(
-        f"{temp}°F",
-        x=25, y=10,
-        color=(255, 255, 255)
-    )
-    
-    self.display_manager.update_display()
-```
-
-### Supported Weather Conditions
-
-The `draw_weather_icon()` method automatically maps condition strings to appropriate icons:
-
-- `"clear"`, `"sunny"` → Sun icon
-- `"clouds"`, `"cloudy"`, `"partly cloudy"` → Cloud icon
-- `"rain"`, `"drizzle"`, `"shower"` → Rain icon
-- `"snow"`, `"sleet"`, `"hail"` → Snow icon
-- `"thunderstorm"`, `"storm"` → Storm icon
-
-### Custom Weather Icons
-
-For more control, use individual icon methods:
-
-```python
-# Draw specific icons
-self.display_manager.draw_sun(x=10, y=10, size=16)
-self.display_manager.draw_cloud(x=10, y=10, size=16, color=(150, 150, 150))
-self.display_manager.draw_rain(x=10, y=10, size=16)
-self.display_manager.draw_snow(x=10, y=10, size=16)
-```
-
-### Text with Weather Icons
-
-Use `draw_text_with_icons()` to combine text and icons:
-
-```python
-icons = [
-    ("sun", 5, 5),      # Sun icon at (5, 5)
-    ("cloud", 100, 5)   # Cloud icon at (100, 5)
-]
-
-self.display_manager.draw_text_with_icons(
-    "Weather: Sunny, Cloudy",
-    icons=icons,
-    x=10, y=20,
-    color=(255, 255, 255)
-)
-```

+`draw_cloud()`, `draw_rain()`, `draw_snow()` and `draw_text_with_icons()` —
+are deprecated, removed in 3.7.0. Draw your own icons instead: render them
+onto a PIL image and paste it onto `self.display_manager.image`, or ship

+# Architecture
+
+A map of the codebase for a new contributor: which process does what, how
+they talk to each other, and where to start reading for common changes.
+
+## Processes
+
+| systemd unit | Runs as | Runs | Installed by |
+|---|---|---|---|
+| `ledmatrix.service` | root | [`run.py`](../run.py) → `DisplayController` | [`install_service.sh`](../scripts/install/install_service.sh) |
+| `ledmatrix-web.service` | the installing user | [`start_web_conditionally.py`](../scripts/utils/start_web_conditionally.py) → [`web_interface/start.py`](../web_interface/start.py) (Flask, port 5000) | `install_service.sh`, [`install_web_service.sh`](../scripts/install/install_web_service.sh) |
+| `ledmatrix-update-verify.path` / `.service` | the web user | Health check after an automatic update | the same installers, or [`src/auto_update_setup.py`](../src/auto_update_setup.py) at runtime |
+| `ledmatrix-wifi-monitor.service` | root | [`wifi_monitor_daemon.py`](../scripts/utils/wifi_monitor_daemon.py) | [`install_wifi_monitor.sh`](../scripts/install/install_wifi_monitor.sh) |
+| `ledmatrix-mqtt-bridge.service` | root | [MQTT bridge](../integrations/mqtt_bridge/README.md) (optional) | [`install_mqtt_bridge.sh`](../scripts/install/install_mqtt_bridge.sh) |
+| `ledmatrix-dns-fix.service` | root | DNS workaround (optional) | [`install_dns_fix.sh`](../scripts/install/install_dns_fix.sh) |
+
+Unit templates are in [`systemd/`](../systemd/README.md). The display runs as
+root because the LED matrix library needs direct GPIO access. The web
+interface runs unprivileged and uses a fixed list of `sudo` rules for the
+few privileged things it does; see [PERMISSIONS.md](PERMISSIONS.md).
+
+`start_web_conditionally.py` exits without starting Flask when
+`web_display_autostart` is explicitly false in `config.json`.
+
+## How the two main processes share state
+
+The display and the web interface are separate processes that never call
+each other. They share three things:
+
+1. **`config/config.json` and `config/config_secrets.json`.** The web
+   interface writes them through `ConfigManager`
+   ([`src/config_manager.py`](../src/config_manager.py)); the display
+   notices through `ConfigService` (below).
+2. **The disk cache**, `/var/cache/ledmatrix` (owned `root:ledmatrix`,
+   setgid, files `0660`), read and written through `CacheManager`
+   ([`src/cache_manager.py`](../src/cache_manager.py),
+   [`src/cache/disk_cache.py`](../src/cache/disk_cache.py)). Readers in the
+   other process pass `memory_ttl=0` so they do not serve a stale in-memory
+   copy.
+3. **A few files in `/tmp`.**
+
+| State | Where | Written by | Read by |
+|---|---|---|---|
+| On-demand request | cache `display_on_demand_request` | web: `start_on_demand_display()` / `stop_on_demand_display()` in [`api_v3/display.py`](../web_interface/blueprints/api_v3/display.py) | display: `_poll_on_demand_requests()` |
+| On-demand state | cache `display_on_demand_state` | display: `_publish_on_demand_state()` | web: `/api/v3/display/on-demand/status` |
+| Current screen | cache `display_current_state` | display | web: `/api/v3/display/current-status` |
+| Plugin errors | cache `plugin_error_snapshot` | display: `ErrorSnapshotPublisher` ([`src/error_aggregator.py`](../src/error_aggregator.py)) | web: `read_error_report()` for `/api/v3/errors/*` |
+| Error clear | cache `plugin_error_clear_request` | web | display |
+| Font usage | cache `font_usage_snapshot` | display: `FontUsagePublisher` ([`src/font_usage.py`](../src/font_usage.py)) | web: Fonts tab |
+| Plugin health | cache `plugin_health:<id>` | display (web writes on reset) | web: `/api/v3/plugins/health` |
+| Preview frame | `/tmp/led_matrix_preview.png` | display: `DisplayManager`, gated by [`snapshot_policy`](../src/common/snapshot_policy.py) | web: display SSE stream, `/api/v3/health` (file age) |
+| Preview viewer marker | `/tmp/led_matrix_preview_viewer` | web, while a preview is open | display: writes full-rate snapshots only while it is fresh |
+| Hardware init status | `/tmp/led_matrix_hw_status.json` | display | web: `/api/v3/hardware/status` |
+
+The on-demand start route also restarts `ledmatrix.service` by default so the
+request takes effect straight away.
+
+## Display loop
+
+[`src/display_controller.py`](../src/display_controller.py), class
+`DisplayController`. `__init__` loads config, starts the cache and the
+error-snapshot publisher, runs the startup validator, creates the
+`DisplayManager` ([`src/display_manager.py`](../src/display_manager.py)),
+`FontManager` and `PluginManager`, loads the enabled plugins in parallel,
+runs an initial `update()` pass within a 20-second budget
+(`_INITIAL_UPDATE_BUDGET_SECONDS`; a plugin that misses it is deferred to
+the scheduler), and sets up Vegas mode.
+
+`run()` is the main loop. Each pass, in order: apply a pending plugin
+enable/disable, poll on-demand requests, run scheduled plugin updates, check
+the on/off schedule and brightness, then show one screen. Priority is
+on-demand, then WiFi status messages, then live priority, then Vegas mode,
+then normal rotation.
+
+- **Rotation.** `available_modes` is the ordered list of display modes;
+  `current_mode_index` advances after each screen.
+  `_apply_plugin_rotation_order()` applies `display.plugin_rotation_order`.
+- **Durations.** `_get_display_duration()`: `display.display_durations[mode]`,
+  else the plugin's `get_display_duration()`, else 30 s. Plugins that
+  support dynamic duration run until `is_cycle_complete()`, capped by
+  `display.dynamic_duration.max_duration_seconds` (default 180 s).
+- **On-demand.** A request from the web interface pins one plugin (or mode)
+  for a duration. `_activate_on_demand()` / `_clear_on_demand()`; the
+  session is saved under `display_on_demand_config` so it survives a
+  restart. It also keeps the display on during scheduled off hours.
+- **Live priority.** `_check_live_priority()` looks for a plugin whose
+  `has_live_priority()` and `has_live_content()` are both true and switches
+  to it, rotating between several live games.
+- **Schedule and dim schedule.** `_check_schedule()` reads `schedule`;
+  `_check_dim_schedule()` reads `dim_schedule` and
+  `display.hardware.brightness`. Both are re-evaluated once a minute.
+- **Long screens.** While a screen is showing (a dwell, a scroll, a Vegas
+  iteration), `_service_pending_changes()` repeats the on-demand, schedule
+  and brightness checks every 0.25 s, so a change does not wait for the
+  screen to end.
+- **Config hot reload.** `ConfigService`
+  ([`src/config_service.py`](../src/config_service.py)) polls the config and
+  secrets files' mtimes every 2 s and notifies subscribers when the content
+  changes. The controller refreshes its cached settings; enabling or
+  disabling a plugin queues `_reconcile_enabled_plugins()`, which loads or
+  unloads it on the display thread; each plugin gets `on_config_change()`
+  for its own section. Set `LEDMATRIX_HOT_RELOAD=false` to turn this off.
+  Matrix hardware settings are only read at start-up.
+- **Vegas mode.** [`src/vegas_mode/`](../src/vegas_mode/): the display loop
+  calls `VegasModeCoordinator.run_iteration()`
+  ([`coordinator.py`](../src/vegas_mode/coordinator.py)) when
+  `display.vegas_scroll.enabled` is set. `PluginAdapter` gets each plugin's
+  content (`get_vegas_content()`, else its `scroll_helper` image, else a
+  capture of `display()`), `StreamManager` orders it and `RenderPipeline`
+  scrolls it. See [ADVANCED_FEATURES.md](ADVANCED_FEATURES.md).
+- **Multi-display sync.** `DisplaySyncManager`
+  ([`src/common/sync_manager.py`](../src/common/sync_manager.py)), enabled by
+  `sync.role`: a leader sends a follower its share of each frame over UDP
+  (port 5765).
+
+## Plugin system
+
+[`src/plugin_system/`](../src/plugin_system/):
+
+| Area | Where |
+|---|---|
+| Base class plugins implement | [`base_plugin.py`](../src/plugin_system/base_plugin.py) (`BasePlugin`, `VegasDisplayMode`) |
+| Finding a plugin's directory | [`plugin_dirs.py`](../src/plugin_system/plugin_dirs.py): manifest `id` first, then directory `<id>` or `ledmatrix-<id>` |
+| Discovery, load, unload, scheduled updates | [`plugin_manager.py`](../src/plugin_system/plugin_manager.py) (`PluginManager`) |
+| Import and instantiate | [`plugin_loader.py`](../src/plugin_system/plugin_loader.py) (`PluginLoader.load_plugin()`: dependencies, module, class) |
+| Timeouts | [`plugin_executor.py`](../src/plugin_system/plugin_executor.py) (`PluginExecutor`, 30 s default; a timed-out thread is abandoned, not killed) |
+| Circuit breaker | [`plugin_health.py`](../src/plugin_system/plugin_health.py) (`PluginHealthTracker`: 3 consecutive failures open the circuit for 300 s) |
+| Resource metrics | [`resource_monitor.py`](../src/plugin_system/resource_monitor.py) |
+| Config schemas and defaults | [`schema_manager.py`](../src/plugin_system/schema_manager.py) |
+| Install, update, uninstall | [`store_manager.py`](../src/plugin_system/store_manager.py) (`PluginStoreManager`), with its methods split across [`store_registry.py`](../src/plugin_system/store_registry.py) (registry, GitHub), [`store_install.py`](../src/plugin_system/store_install.py) and [`store_update.py`](../src/plugin_system/store_update.py) |
+| Core-version gate | [`compatibility.py`](../src/plugin_system/compatibility.py) |
+
+Discovery scans only `plugin_system.plugins_directory` (default
+`plugin-repos/`). Scheduled `update()` calls run on one background worker
+thread; a per-plugin lock keeps `display()` from running during an update.
+
+**Store flow.** `install_plugin()` renames any existing copy aside
+(`<id>.standalone-backup-preinstall`), installs the new one, and puts the old
+copy back if the install fails. Monorepo plugins come from the GitHub Trees
+API, falling back to the repository ZIP; other plugins by `git clone` or
+download. The manifest is checked (see
+[required fields](PLUGIN_API_REFERENCE.md#manifest-required-fields)), the core
+version gate runs, then dependencies are installed as root through
+`scripts/fix_perms/safe_pip_install.sh`. `update_plugin()` pulls git
+installs, undoing a pull whose new version is incompatible, and reinstalls
+everything else through `_reinstall_with_rollback()`.
+
+## Web interface
+
+- **App.** [`web_interface/app.py`](../web_interface/app.py) builds the
+  Flask `app` at import time, creates the managers, and registers two
+  blueprints. `web_interface/start.py` runs it on port 5000.
+- **Pages.** [`blueprints/pages_v3.py`](../web_interface/blueprints/pages_v3.py)
+  serves the shell `templates/v3/base.html` at `/` and each tab as a
+  partial at `/partials/<name>` (templates in
+  `web_interface/templates/v3/partials/`). Plugin configuration tabs are
+  rendered from the plugin's schema by `plugin_config.html`.
+- **API.** [`blueprints/api_v3/`](../web_interface/blueprints/api_v3/) is one
+  blueprint at `/api/v3`, split by area: `backup.py`, `config.py`,
+  `display.py`, `fonts.py`, `misc.py` (health, logs, errors, cache, sync),
+  `starlark.py`, `system.py` (service actions, updates, git), `wifi.py`, and
+  the plugin routes: `plugins.py` (installed list, enable/disable, plugin
+  actions), `plugin_store.py` (install, update, uninstall, store),
+  `plugin_config.py` (config, schema, reset), `plugin_assets.py` (uploads,
+  plugin static files), `plugin_health.py` (health, metrics, limits),
+  `plugin_operations.py` (operation history, state reconciliation) and
+  `plugin_calendar.py`. `__init__.py` defines the blueprint and shared helpers and
+  imports the modules so their routes register. Endpoints are listed in
+  [REST_API_REFERENCE.md](REST_API_REFERENCE.md).
+- **Front end.** HTMX loads each tab's partial on first open
+  (`hx-trigger="loadtab"`); Alpine.js holds page state. Scripts are in
+  `web_interface/static/v3/js/`; form widgets are bundled from
+  [`js/widgets/`](../web_interface/static/v3/js/widgets/README.md).
+- **Server-sent events** (`app.py`): `/api/v3/stream/stats` (CPU, memory,
+  temperature, service state, every 10 s), `/api/v3/stream/display` (preview
+  frames when the PNG changes) and `/api/v3/stream/logs` (journal of both
+  services). One generator thread per stream is shared by all clients.
+
+## Updates
+
+- **Update Code** on the Overview tab and the automatic updater both call
+  `perform_core_update()` in
+  [`api_v3/system.py`](../web_interface/blueprints/api_v3/system.py):
+  `git pull --rebase`, reinstall changed requirement files, report whether a
+  restart is needed.
+- **Automatic updates** (`auto_update.enabled`, off by default):
+  `AutoUpdater` in [`web_interface/auto_update.py`](../web_interface/auto_update.py)
+  runs in the web process, checks every 30 minutes, and updates at most
+  weekly between 02:00 and 05:00. Before pulling it copies
+  [`scripts/utils/auto_update_verify.py`](../scripts/utils/auto_update_verify.py)
+  to `data/auto_update_verifier.py`, then writes
+  `data/auto_update_verify.request`. That file triggers
+  `ledmatrix-update-verify.path`, which runs the verifier as a separate unit
+  (so restarting the web service does not kill it). The verifier restarts
+  both services, waits for the web API to answer and the display service to
+  stay up, and on failure resets to the previous commit and restarts again.
+  Plugin updates run only after a verified core update. State is in
+  `data/auto_update_state.json` and `data/auto_update_pending.json`.
+- **Startup validator.** `StartupValidator`
+  ([`src/startup_validator.py`](../src/startup_validator.py)) runs twice in
+  `DisplayController.__init__`: config and cache directory first, then
+  enabled plugins once the plugin manager exists. It also warns when an
+  installed systemd unit differs from its template in `systemd/`. Results
+  are logged; startup continues either way.
+
+## Where to start reading
+

+in `DisplayManager._setup_matrix` (`src/display_manager.py`). Defaults are the
+`config/config.template.json` values: `ConfigManager` adds any key missing from
+`config.json` from the template on load, so `DisplayManager`'s own fallbacks
+don't apply on a normal install.
+
+The ranges are what the pinned rgbmatrix library and its Python binding accept
+(`src/matrix_support.py`). The config API refuses anything else; a value
+hand-edited into `config.json` makes the display log the setting and run in
+fallback mode instead of starting the matrix.

-# Creating Skins
-
-> **Not supported yet: skins don't render with the current scoreboard
-> plugins.** The only render hook is `SportsCore._render_game()` in
-> `src/base_classes/sports/core.py`, and no current scoreboard (monorepo or
-> third-party) builds on `src.base_classes`, so a skin you build here passes
-> `validate_skin.py` but never appears on the matrix. The web UI and Plugin
-> Store don't offer skins for that reason. Details:
-> [SKIN_SYSTEM.md](SKIN_SYSTEM.md#status-not-supported-yet). The guide below
-> stays accurate for the skin API itself.
-
-A skin restyles a sports scoreboard (live / recent / upcoming) without
-forking the plugin: the plugin keeps fetching data, scheduling, caching, and
-doing vegas mode; your skin only draws. Architecture background:
-[SKIN_SYSTEM.md](SKIN_SYSTEM.md).
-
-## Quick start
-
-```bash
-cp -r skins/example-classic-baseball skins/my-skin
-# edit skins/my-skin/skin.json  -> set id ("my-skin"), name, author, class_name
-# edit skins/my-skin/skin.py    -> rename the class, start restyling
-python scripts/validate_skin.py --skin my-skin
-```
-
-The validator renders your skin against bundled fixture games at several
-panel sizes with **no hardware, no network, no running service**, saves PNGs
-(plus 4x previews) to `skin_renders/`, and fails loudly on errors. Iterate:
-edit → validate → look at the PNGs.
-
-To select it, add to your plugin's section in `config/config.json` (this is
-stored and validated, but has no visible effect until a scoreboard uses the
-skin hook — see the note at the top):
-
-```json
-"baseball-scoreboard": {
-  "skin": "my-skin",
-  "skin_options": { }
-}
-```
-
-The web UI's **Visual Skin** dropdown is hidden while skins are unsupported.
-`"skin"` also accepts a per-mode mapping:
-`{"live": "my-skin", "recent": "built-in"}`.
-
-## The manifest (`skin.json`)
-
-```json
-{
-  "id": "my-skin",
-  "name": "My Skin",
-  "version": "1.0.0",
-  "author": "you",
-  "description": "What it looks like",
-  "skin_api_version": "1.0.0",
-  "targets": {
-    "sports": ["baseball"],
-    "sport_keys": ["mlb", "milb"],
-    "plugins": []
-  },
-  "entry_point": "skin.py",
-  "class_name": "MySkin",
-  "modes": ["live", "recent", "upcoming"],
-  "preview": "preview.png"
-}
-```
-
-Field notes: `id` must equal the directory name; `skin_api_version`'s major
-version must match the host's `SKIN_API_VERSION` or the skin is refused at
-load; `targets` takes sport families (`sports`), exact sport keys
-(`sport_keys`), and/or exact plugin ids (`plugins`) — any match applies.
-
-## The renderer (`skin.py`)
-
-```python
-from src.skin_system.skin_base import ScoreboardSkin, SkinContext
-
-class MySkin(ScoreboardSkin):
-    def render_live(self, ctx: SkinContext, game: dict) -> bool:
-        score = f"{game.get('away_score', '0')}-{game.get('home_score', '0')}"
-        fit = ctx.layout.fit_text(score, ctx.layout.bounds)
-        ctx.draw_fit(fit, ctx.layout.bounds)
-        return True   # True = "I drew it"; False = use the built-in layout
-```
-
-Implement only the modes you care about — anything else falls back to the
-plugin's built-in rendering. Return `False` to decline a specific game (e.g.
-a layout that only makes sense while a game is live).
-
-### The rules (they keep your skin from breaking the display)
-
-1. **Draw only onto `ctx.canvas`** (via the helpers or `ctx.draw`). Never
-   reassign `ctx.canvas`, never touch the display or call any update method.
-2. **No I/O in render paths.** No network, no file loads per frame —
-   `render_live` runs every display pass, and a slow render stalls the whole
-   matrix (the host warns at >150 ms). Use `ctx.load_logo` (cached) and
-   `cache_key=` for images.
-3. **Derive everything from `(ctx, game)`.** Skins must be stateless: the
-   live/recent/upcoming modes each get their own instance.
-4. **Always `.get()` optional keys.** Only the guaranteed keys below are
-   promised to exist.
-5. **Never hardcode pixel positions for the panel.** Use `ctx.width`/
-   `ctx.height`, `ctx.layout` regions and `fit_text` — your skin will be run
-   at sizes you didn't test (64x32, 128x64, vegas cards).
-6. **No third-party dependencies.** Stdlib + PIL + what `ctx` provides.
-
-A skin that raises 3 renders in a row is disabled until the service restarts
-(the built-in layout takes over), so a bug is cosmetic — but check your logs.
-
-## SkinContext reference
-
-| Member | What it is |
-|---|---|
-| `ctx.canvas` / `ctx.draw` | Fresh RGB `PIL.Image` at display size + its `ImageDraw` (raw-PIL escape hatch) |
-| `ctx.width`, `ctx.height` | Canvas size — the only size truth |
-| `ctx.layout` | `LayoutContext` (see [ADAPTIVE_LAYOUT.md](ADAPTIVE_LAYOUT.md)): `bounds`, `fit_text`, `fit_text_proportional`, `fit_image`, `px`, `by_tier` |
-| `ctx.draw_fit(fit, box, color, align, valign)` | Draw a `fit_text` result aligned in a `Region` (handles BDF fonts) |
-| `ctx.draw_text(text, x, y, color, font)` | Positioned text (handles BDF fonts) |
-| `ctx.draw_image(img, box, mode, align, valign, cache_key)` | Fit + paste an image with alpha; no-ops on `None` |
-| `ctx.load_logo("home" \| "away")` | Team logo as RGBA, or `None` (always handle `None`). Cached after first use; see note below |
-| `ctx.draw_text_outlined(text, (x, y), font, fill, outline_color)` | The classic scorebug outlined text (TTF fonts only) |
-| `ctx.fonts` | The host's font dict — keys `score`, `time`, `team`, `status`, `detail`, `rank` |
-| `ctx.options` | Your user's `skin_options` from config |
-| `ctx.sport`, `ctx.view_model_version`, `ctx.logger` | Context metadata + logger |
-
-**A note on `ctx.load_logo` vs the no-I/O rule:** `load_logo` is the one
-sanctioned exception. It goes through the host's logo cache — after the
-first call per team it's a pure in-memory lookup. If a logo file is missing
-on disk, the *first* call may download it, exactly like the built-in
-renderer does for the same game (a skin is never worse than built-in here).
-Always pass a stable `cache_key` when drawing it, never load image files
-yourself in a render path, and always handle `None`.
-
-The default layout idiom — carve regions, then fit text into them:
-
-```python
-from src.adaptive_layout import scoreboard_regions
-
-regions = scoreboard_regions(ctx.layout.bounds, ctx=ctx.layout)
-ctx.draw_image(ctx.load_logo("away"), regions.away_slot, cache_key=f"logo:{game.get('away_abbr')}")
-ctx.draw_image(ctx.load_logo("home"), regions.home_slot, cache_key=f"logo:{game.get('home_abbr')}")
-fit = ctx.layout.fit_text("3-5", regions.score_area)
-ctx.draw_fit(fit, regions.score_area)
-```
-
-`Region` supports `split_h`/`split_v`/`inset`/`top_band`/`bottom_band`/
-`left_col`/`right_col` for custom carves. Raw `ctx.draw.rectangle/polygon/
-ellipse/...` is always available for custom marks (see the bases diamond in
-the example skin).
-
-## The game view model
-
-Guaranteed for every sport (view model v1.0 — renaming these breaks skins and
-is treated as a breaking change upstream):
-
-| Key | Notes |
-|---|---|
-| `id` | Event id (string) |
-| `status_text` | Display-ready status, e.g. `"Final"`, `"7:30 PM"`, `"Bot 7th"` |
-| `is_live`, `is_final`, `is_upcoming`, `is_halftime` | Booleans |
-| `game_date`, `game_time` | Pre-formatted local date/time strings |
-| `start_time_utc` | UTC `datetime` |
-| `home_abbr`, `away_abbr` | Team abbreviations (can be 2–5 chars — fit, don't assume) |
-| `home_id`, `away_id` | Team ids |
-| `home_score`, `away_score` | **Strings**, not ints |
-| `home_record`, `away_record` | `"58-33"` or `""` (0-0 records are blanked) |
-| `home_logo_path`, `away_logo_path` | Prefer `ctx.load_logo` over touching these |
-
-Sport extras (present for that sport, still `.get()` defensively):
-
-- **baseball**: `inning` (int), `inning_half` (`"top"`/`"bottom"`), `balls`,
-  `strikes`, `outs` (ints), `bases_occupied` (`[first, second, third]`
-  booleans), `series_summary` (str)
-- **football**: `period`, `period_text`, `clock`, `home_timeouts`,
-  `away_timeouts`, `down_distance_text`, `down_distance_text_long`,
-  `is_redzone`, `possession`, `possession_indicator` (`"home"`/`"away"`),
-  `scoring_event`
-- **basketball**: `period`, `period_text`, `clock`
-- **hockey**: `period`, `period_text`, `clock`, `power_play`, `penalties`,
-  `home_shots`, `away_shots`
-
-Optional everywhere (only when the user enabled the feature): `odds` (dict),
-`series_summary`, rankings-related fields.
-
-Fixture copies of these dicts live in `src/skin_system/fixtures/` — that's
-exactly what the validator feeds your skin.
-
-## Vegas mode
-
-You get vegas support for free: vegas captures the normal display output,
-which is already your skin's rendering. Optionally implement
-`render_vegas_card(ctx, game)` to return a purpose-built card at
-`ctx.width x ctx.height` (sizes vary — never assume 128x32).
-
-## Building a skin with Claude Code
-
-Skins are ideal Claude Code projects: small, isolated, and verifiable with
-one command. Paste this to start:
-
-> You are building a **display skin** for LEDMatrix — a visual overlay for a
-> sports scoreboard on a small LED matrix (commonly 128x32 or 64x32 pixels).
-> First read `docs/CREATING_SKINS.md` and the reference skin in
-> `skins/example-classic-baseball/`.
->
-> Rules:
-> - Create/modify files ONLY under `skins/<my-skin-id>/`. Do NOT modify
->   anything in `src/`, `scripts/`, the plugins, or any other skin.
-> - Render only from the `game` dict and `ctx` helpers. No network calls, no
->   per-frame file I/O, no new pip dependencies, no touching the display —
->   draw onto `ctx.canvas` and return True.
-> - Use `ctx.layout` regions and `fit_text` for positioning so the skin works
->   at any panel size; use `.get()` for every optional game key.
-> - After every change run
->   `python scripts/validate_skin.py --skin <my-skin-id>` and LOOK at the
->   PNGs it writes to `skin_renders/` (the `_x4.png` files are easiest to
->   read). Iterate until it passes and looks right at both 128x32 and 64x32.
->
-> What I want it to look like: <describe your layout — where logos, score,
-> status go; colors; what shows during live vs upcoming vs final>
-
-Tips that keep Claude (and you) out of trouble:
-
-- One mode at a time: get `render_live` right before touching the others —
-  unimplemented modes automatically use the built-in look.
-- Ask for edge-case renders: long team abbreviations, missing logos
-  (`ctx.load_logo` returning `None`), 0-0 records, extra innings/OT.
-- If the render looks cramped at 64x32, ask Claude to use
-  `ctx.layout.by_tier(...)` to drop elements on small panels rather than
-  shrinking everything.
-- Never let it "fix" a problem by editing `src/` — if the skin can't do
-  something within its directory, that's a feature request, not a workaround.

-- [ ] `python scripts/validate_skin.py --skin <id> --size 128x32 --size 64x32 --size 128x64` passes
-- [ ] Looked at every PNG in `skin_renders/` — nothing clipped or overlapping
-- [ ] Handles a missing logo (`None`) without crashing — temporarily point a
-      fixture's logo path at a nonexistent file to test
-- [ ] Long abbreviations (`"TA&M"`, 4–5 chars) don't overflow
-- [ ] No render warning above the time budget
-- [ ] `skin.json`: `id` matches the directory, `version` set,
-      `skin_api_version` matches the host, targets correct
-- [ ] `preview.png` added (grab your favorite `_x4` render)
-- [ ] Tested on real hardware if you have it — a Pi is much slower than your
-      dev machine
-
-Distribute by publishing the directory as a git repo (users
-`git clone <repo> skins/<id>`). Registry entries with `"type": "skin"` are
-hidden and refused by the Plugin Store while skins are unsupported (see
-[SKIN_SYSTEM.md](SKIN_SYSTEM.md) §Distribution).
-
-**Trust note:** a skin is Python running inside the display service — the
-same trust level as a plugin. Review code before installing skins from
-others.

 ## Overview
 
-The enhanced FontManager provides comprehensive font management for the LEDMatrix application with support for:
-- Manager font registration and detection
-- Plugin font management
-- Manual font overrides via web interface
-- Performance monitoring and caching
-- Dynamic font discovery
+[`src/font_manager.py`](../src/font_manager.py) loads and caches the TTF and
+BDF fonts in `assets/fonts/`, registers fonts that plugins ship, and records
+which plugin uses which font so the web UI can show it.
 
-## Architecture
+Several methods are deprecated and will be removed in LEDMatrix 3.7.0; they
+log a warning on first call. They are listed in
+[Deprecated methods](#deprecated-methods) below, and the full set is pinned in
+[`test/test_deprecation.py`](../test/test_deprecation.py).
 
-### Manager-Centric Design
+## Getting the FontManager
 
-Managers define their own fonts, but the FontManager:
-1. **Loads and caches fonts** for performance
-2. **Detects font usage** for visibility
-3. **Allows manual overrides** when needed
-4. **Supports plugin fonts** with namespacing
-
-### Font Resolution Flow
-
-```
-Manager requests font → Check manual overrides → Apply manager choice → Cache & return
-```
-
-## For Manager Developers
-
-### Basic Font Usage
+There is one shared FontManager per display process. The display controller
+creates it and hands it to the `PluginManager`, so a plugin reaches it
+through its `plugin_manager`:
 
 ```python
-from src.font_manager import FontManager
-
-class MyManager:
-    def __init__(self, config, display_manager, cache_manager):
-        self.font_manager = display_manager.font_manager  # Access shared FontManager
-        self.manager_id = "my_manager"
-        
-    def display(self):
-        # Define your font choices
-        element_key = "my_manager.title"
-        font_family = "press_start"
-        font_size_px = 10
-        color = (255, 255, 255)  # RGB white
-        
-        # Register your font choice (for detection and future overrides)
-        self.font_manager.register_manager_font(
-            manager_id=self.manager_id,
-            element_key=element_key,
-            family=font_family,
-            size_px=font_size_px,
-            color=color
-        )
-        
-        # Get the font (checks for manual overrides automatically)
-        font = self.font_manager.resolve_font(
-            element_key=element_key,
-            family=font_family,
-            size_px=font_size_px
-        )
-        
-        # Use the font for rendering
-        self.display_manager.draw_text(
-            "Hello World",
-            x=10, y=10,
-            color=color,
-            font=font
-        )
+class MyPlugin(BasePlugin):
+    def __init__(self, plugin_id, config, display_manager, cache_manager, plugin_manager):
+        super().__init__(plugin_id, config, display_manager, cache_manager, plugin_manager)
+        self.font_manager = self._get_font_manager()
 ```
 
-### Advanced Font Usage
+`BasePlugin._get_font_manager()` returns `plugin_manager.font_manager`, or a
+standalone FontManager when none is available (test harnesses, mocks).
+`DisplayManager` has **no** `font_manager` attribute —
+`display_manager.font_manager` raises `AttributeError`.

-## For Plugin Developers
+`resolve_font()` applies any entry for `element_key` in
+`config/font_overrides.json`, maps a plugin-local family to its namespaced
+name when `plugin_id` is passed, and then calls `get_font(family, size_px)`.
+On error it returns a fallback font rather than raising.
 
-> **Note**: plugins that ship their own fonts via a `"fonts"` block

-> `FontManager.register_plugin_fonts()`). The `plugin://…` source
-> URIs documented below are resolved relative to the plugin's

+`get_font(family, size_px)` looks the family up in `font_catalog` and loads
+it (cached per family and size).
 
-### Plugin Font Registration
+## Font families
 
-In your plugin's `manifest.json`:
+At start-up the FontManager scans `assets/fonts/` for `.ttf` and `.bdf`
+files. Each becomes a family named after the file, lower-cased and without
+the extension (`PressStart2P-Regular.ttf` → `pressstart2p-regular`). Four
+aliases are added on top:
+
+| Alias | File |
+|---|---|
+| `press_start` | `assets/fonts/PressStart2P-Regular.ttf` |
+| `four_by_six` | `assets/fonts/4x6-font.ttf` |
+| `five_by_seven` | `assets/fonts/5x7.bdf` |
+| `tom_thumb` | `assets/fonts/tom-thumb.bdf` |
+
+Read the catalog directly: `font_manager.font_catalog` is a dict of family
+name to file path. Files added later are picked up on the next start of the
+display service.
+
+## Plugin fonts
+
+Plugins that ship their own fonts declare them in a `"fonts"` block in
+`manifest.json`. The plugin manager calls
+`FontManager.register_plugin_fonts()` during plugin load. `plugin://…`
+sources are resolved relative to the plugin's install directory.

+Registered families are namespaced as `<plugin_id>::<family>`. Pass
+`plugin_id` to `resolve_font()` to use the short name:

-class PluginManager:

-        
-        self.display_manager.draw_text("Plugin Text", font=font)
-```
-
-## Manual Font Overrides
-
-Users can override any font through the web interface:
-
-1. Navigate to **Fonts** tab
-2. View **Detected Manager Fonts** to see what's currently in use
-3. In **Element Overrides** section:
-   - Select the element (e.g., "nfl.live.score")
-   - Choose a different font family
-   - Choose a different size
-   - Click **Add Override**
-
-Overrides are stored in `config/font_overrides.json` and persist across restarts.
-
-### Programmatic Overrides
-
-```python
-# Set override
-font_manager.set_override(
-    element_key="nfl.live.score",
-    family="four_by_six",
-    size_px=8
+font = self.font_manager.resolve_font(
+    element_key=f"{self.plugin_id}.text",
+    family="custom_font",          # resolved as "my-plugin::custom_font"
+    size_px=10,
+    plugin_id=self.plugin_id,
 )
-
-# Remove override
-font_manager.remove_override("nfl.live.score")
-
-# Get all overrides
-overrides = font_manager.get_overrides()
 ```
 
-## Font Discovery
+## Overrides
 
-### Available Fonts
+`resolve_font()` still honours `config/font_overrides.json` (a map of
+element key to `family` and/or `size_px`), which is read once at start-up.
+The methods that edit it — `set_override()`, `remove_override()`,
+`get_overrides()` — are deprecated, and there is no web UI or REST endpoint
+for overrides (the override editor and `/api/v3/fonts/overrides` were
+removed). To let users choose a font, add a field to your plugin's config
+schema.
 
-The FontManager automatically scans `assets/fonts/` for TTF and BDF fonts:
+## Font usage in the web UI
+
+The web UI's **Fonts** tab lists, uploads, previews and deletes the font
+files in `assets/fonts/`. The web interface runs in its own process and has
+no FontManager, so the display service publishes which plugin uses which
+font ([`src/font_usage.py`](../src/font_usage.py)), and the tab's **Used by**
+column reads it:
+
+- **Source**: `register_manager_font()` registrations of the loaded
+  plugins. `get_font()` and `resolve_font()` do not know the calling plugin
+  and are not counted, and neither is a plugin that opens a font file
+  directly with PIL — register the fonts your plugin draws with if you want
+  them listed.
+- **Names**: a family, alias or path is resolved through `font_catalog` to
+  the file it loads and reported under that file's name without extension
+  (`PressStart2P-Regular`, `4x6-font`, `5x7`, `tom-thumb`), which is how the
+  Fonts tab keys its rows. Fonts outside `assets/fonts/` (a plugin's own
+  `plugin_id::family` fonts) and families that resolve to nothing are left
+  out.
+- **When**: a daemon thread started once plugins have loaded checks every
+  10 seconds and writes the `font_usage_snapshot` cache key only when the
+  usage changed (and once a day, so the cache's cleanup never expires it).
+  Unloading a plugin drops its registrations (`forget_manager_fonts`).
+- **Unknown**: until the display service has published, the column reads
+  "unknown" and `GET /api/v3/fonts/catalog` returns `used_by: null`.
+- The tab warns before deleting a font that a loaded plugin registered.
+
+## Text measurement
 
 ```python
-# Get all available fonts
-fonts = font_manager.get_available_fonts()
-# Returns: {'press_start': 'assets/fonts/PressStart2P-Regular.ttf', ...}
-
-# Check if font exists
-if "my_font" in fonts:
-    font = font_manager.get_font("my_font", 10)
-```
-
-### Adding Custom Fonts
-
-Place font files in `assets/fonts/` directory:
-- Supported formats: `.ttf`, `.bdf`
-- Font family name is derived from filename (without extension)
-- Will be automatically discovered on next initialization
-
-## Performance Monitoring
-
-```python
-# Get performance stats
-stats = font_manager.get_performance_stats()
-
-print(f"Cache hit rate: {stats['cache_hit_rate']*100:.1f}%")
-print(f"Total fonts cached: {stats['total_fonts_cached']}")
-print(f"Failed loads: {stats['failed_loads']}")
-print(f"Manager fonts: {stats['manager_fonts']}")
-print(f"Plugin fonts: {stats['plugin_fonts']}")
-```
-
-## Text Measurement
-
-```python
-# Measure text dimensions
 width, height, baseline = font_manager.measure_text("Hello", font)
-
-# Get font height
 font_height = font_manager.get_font_height(font)
 ```
 
-## Best Practices
+## Tips
 
-### For Managers
-
-1. **Register all fonts** you use for visibility
-2. **Use consistent element keys** (e.g., `{manager_id}.{element_type}`)
-3. **Cache font references** if using same font multiple times
-4. **Use `resolve_font()`** not `get_font()` directly to support overrides
-5. **Define sensible defaults** that work well on LED matrix
-
-### For Plugins
-
-1. **Use plugin-relative paths** (`plugin://fonts/...`)
-2. **Include font metadata** (license, description)
-3. **Provide fallback** fonts if custom fonts fail to load
-4. **Test with different display sizes**
-
-### General
-
-1. **BDF fonts** are often better for small sizes on LED matrices
-2. **TTF fonts** work well for larger sizes
-3. **Monospace fonts** are easier to align
-4. **Test on actual hardware** - what looks good on screen may not work on LED matrix
-
-## Migration from Old System
-
-### Old Way (Direct Font Loading)
-```python
-self.font = ImageFont.truetype("assets/fonts/PressStart2P-Regular.ttf", 8)
-```
-
-### New Way (FontManager)
-```python
-element_key = f"{self.manager_id}.text"
-self.font_manager.register_manager_font(
-    manager_id=self.manager_id,
-    element_key=element_key,
-    family="pressstart2p-regular",
-    size_px=8
-)
-self.font = self.font_manager.resolve_font(
-    element_key=element_key,
-    family="pressstart2p-regular",
-    size_px=8

+- BDF fonts usually look better than TTF at small sizes on LED panels.

+  and handles BDF files.
 
 ## Troubleshooting

-- Check font file exists in `assets/fonts/`
-- Verify font family name matches filename (without extension, lowercase)
-- Check logs for font discovery errors

-## Example: Complete Manager Implementation
-
-For a working example of the font manager API in use, see
-`src/font_manager.py` itself and the bundled scoreboard base classes
-in `src/base_classes/` (e.g., `hockey.py`, `football.py`) which
-register and resolve fonts via the patterns documented above.
+Removed in 3.7.0. Each logs a warning on first call.
 
+| Method | Use instead |
+|---|---|
+| `get_available_fonts()`, `get_font_catalog()` | read `font_catalog` |

+| `set_override()`, `remove_override()`, `get_overrides()` | a font field in your plugin's config schema |
+| `get_manager_fonts()`, `get_detected_fonts()` | — |
+| `get_plugin_fonts()`, `unregister_plugin_fonts()` | — |

 # Multi-Root Workspace Setup Guide
 
-This document explains how the LEDMatrix project uses a multi-root workspace to manage plugins as separate Git repositories.
+This document explains how to work on LEDMatrix and the official plugins side
+by side, with one editor workspace and the plugins loaded straight from your
+plugin checkout.
 
 ## Overview
 
-The LEDMatrix project has been migrated from a git submodule implementation to a **multi-root workspace** implementation for managing plugins. This allows:
+Official plugins live in a single repository,
+[ledmatrix-plugins](https://github.com/ChuckBuilds/ledmatrix-plugins), with one
+directory per plugin under `plugins/`. There are no separate per-plugin
+repositories. For development you clone that monorepo **next to** LEDMatrix
+and symlink the plugin directories you are working on into LEDMatrix's
+`plugins/` directory with `scripts/dev/dev_plugin_setup.sh`.
 
-- ✅ Plugins to exist as independent Git repositories
-- ✅ Updates to plugins without modifying the LEDMatrix project
-- ✅ Easy development workflow with all repos in one workspace
-- ✅ Plugin system discovers plugins via symlinks in `plugin-repos/`
+- ✅ Plugin code stays in the monorepo checkout, with its own git history
+- ✅ LEDMatrix discovers the plugins through symlinks in `plugins/`
+  (git-ignored), so the production `plugin-repos/` directory is untouched
+- ✅ `LEDMatrix.code-workspace` opens both repositories in VS Code/Cursor

 ```
 
 ## How It Works
 
-### 1. Plugin Repositories
+### 1. The plugin monorepo
 
-All plugin repositories are cloned to `/home/chuck/Github/` (parent directory of LEDMatrix) as regular Git repositories:
-
-- `ledmatrix-clock-simple/`
-- `ledmatrix-weather/`
-- `ledmatrix-football-scoreboard/`
-- etc.
-
-### 2. Symlinks in plugin-repos/
-
-The `LEDMatrix/plugin-repos/` directory contains symlinks pointing to the actual repositories in the parent directory. This allows the plugin system to discover plugins without modifying the project structure.
-
-### 3. Multi-Root Workspace
-
-The `LEDMatrix.code-workspace` file configures VS Code/Cursor to open all plugin repositories as separate workspace roots, allowing easy development across all repos.
-
-## Setup Scripts
-
-### Initial Setup
-
-If you already have plugin repositories cloned, use the setup script:
+Clone ledmatrix-plugins into the same parent directory as LEDMatrix (the
+workspace file and `scripts/update_plugin_repos.py` look for
+`../ledmatrix-plugins` relative to the LEDMatrix root):
 
 ```bash
-cd /home/chuck/Github/LEDMatrix
-python3 scripts/setup_plugin_repos.py
+cd ~/Github
+git clone https://github.com/ChuckBuilds/ledmatrix-plugins.git
 ```
 
-This script:
-- Reads the workspace configuration
-- Creates symlinks in `plugin-repos/` pointing to actual repos
-- Verifies all links are created correctly
+### 2. Symlinks in plugins/
+
+`scripts/dev/dev_plugin_setup.sh link <name> <path>` creates
+`LEDMatrix/plugins/<name>` as a symlink to a plugin directory. Use the
+plugin's manifest `id` as the name: that is the name the loader and
+`config.json` use, and the script warns when the two differ.
+
+### 3. Multi-root workspace
+
+`LEDMatrix.code-workspace` has two roots: LEDMatrix itself and
+`../ledmatrix-plugins`.
+
+## Setup
+
+### Link plugins
+
+```bash
+cd ~/Github/LEDMatrix
+./scripts/dev/dev_plugin_setup.sh link clock-simple ../ledmatrix-plugins/plugins/clock-simple
+./scripts/dev/dev_plugin_setup.sh list      # show what is linked
+```
+
+If a real (non-symlink) directory of the same name already exists in
+`plugins/`, the script offers to back it up and replace it.
+
+Without a sibling checkout, `./scripts/dev/dev_plugin_setup.sh link-github
+<name>` clones the monorepo into `~/.ledmatrix-dev-plugins/` instead and links
+the plugin from there. See the
+[Plugin Development Guide](PLUGIN_DEVELOPMENT_GUIDE.md).
 
 ### Updating Plugins
 
-To update all plugin repositories:
-
 ```bash
-cd /home/chuck/Github/LEDMatrix
-python3 scripts/update_plugin_repos.py
+cd ~/Github/LEDMatrix
+python3 scripts/update_plugin_repos.py      # git pull in ../ledmatrix-plugins
+# or
+./scripts/dev/dev_plugin_setup.sh update    # git pull in every linked checkout
 ```
 
-This script:
-- Finds all plugins in the workspace
-- Runs `git pull` on each repository
-- Reports which plugins were updated
+The symlinks pick up the new code; restart the display to load it.
 
 ## Configuration
 
-The plugin system is configured in `config/config.json`:
+The loader scans only `plugin_system.plugins_directory` in
+`config/config.json` (default `plugin-repos`). Point it at `plugins` so it
+finds the links:
 
 ```json
 {
   "plugin_system": {
-    "plugins_directory": "plugin-repos",
-    "auto_discover": true,
-    "auto_load_enabled": true
+    "plugins_directory": "plugins"
   }
 }
 ```
 
-The `plugins_directory` points to `plugin-repos/`, which contains symlinks to the actual repositories.
-
 ## Workflow
 
 ### Daily Development
 
 1. **Open Workspace**: Open `LEDMatrix.code-workspace` in VS Code/Cursor
-2. **All Repos Available**: All plugin repos appear as separate folders in the workspace
-3. **Edit Plugins**: Edit plugin code directly in their repositories
-4. **Update Plugins**: Run `update_plugin_repos.py` to pull latest changes
+2. **Edit Plugins**: Edit code under `ledmatrix-plugins/plugins/<plugin>/`
+3. **Test**: `python3 run.py -e` (emulator) or
+   `python3 scripts/check_plugin.py --plugin <id>` from LEDMatrix
+4. **Ship**: Bump `version` in the plugin's `manifest.json`, run
+   `python update_registry.py` in ledmatrix-plugins, commit there
 
 ### Adding New Plugins
 
-1. **Clone Repository**: Clone the new plugin repo to `/home/chuck/Github/`
-2. **Add to Workspace**: Add the plugin folder to `LEDMatrix.code-workspace`
-3. **Create Symlink**: Run `setup_plugin_repos.py` to create the symlink
-
-### Updating Individual Plugins
-
-Since plugins are regular Git repositories, you can update them individually:
-
-```bash
-cd /home/chuck/Github/ledmatrix-weather
-git pull origin master
-```
-
-Or update all at once:
-
-```bash
-cd /home/chuck/Github/LEDMatrix
-python3 scripts/update_plugin_repos.py
-```
-
-## Benefits
-
-1. **No Submodule Hassle**: No need to update `.gitmodules` or run `git submodule update`
-2. **Independent Updates**: Update plugins independently without touching LEDMatrix
-3. **Clean Separation**: Each plugin is a separate repository with its own history
-4. **Easy Development**: Multi-root workspace makes it easy to work across repos
-5. **Automatic Discovery**: Plugin system automatically discovers plugins via symlinks

+# Offscreen Rendering
+
+**Status (2026-09-24):** step 1, offscreen rendering, is implemented
+(`DisplayManager.offscreen()`, the adapter on the prefetch thread, the plugin
+lock). Steps 2 and 3 are proposed. When all three land, this file becomes the
+reference for how plugin content is rendered off the render thread.
+
+First soak of step 1 on hdpi (50 px/s, `pwm_bits` 7, preview open, 8-minute
+runs, A/B/B/A):
+
+| build | late | by 1 | 2 | 3–5 | 6+ | freezes | render-thread fetches |
+|---|---|---|---|---|---|---|---|
+| #628 | 0.53% | 82 | 2 | 3 | 2 | 3 | 6 |
+| step 1 | 0.63% | 78 | 63 | 17 | 2 | 1 | 0 |
+| step 1 | 0.42% | 77 | 23 | 10 | 0 | 0 | 0 |
+| #628 | 0.37% | 84 | 5 | 3 | 3 | 2 | 14 |
+
+It does what it was built to: no plugin is fetched on the render thread, and
+freezes fell from 5 to 1. But frames 2–5 refreshes late rose. The rendering
+moved to the prefetch thread still needs the GIL, and the render thread waits
+for it (risk 5 below). The late rate did not improve overall. The 1–2 s
+freezes appear in both builds and have a separate, not yet identified cause.
+
+The GIL fix, measured on hdpi (90 px/s, `pwm_bits` 8, preview open, 8-minute
+runs after a 2-minute warm-up, order A B C C B A, 2026-09-24). Each arm pools
+two runs, about 81,000 frames:
+
+| arm | late | by 1 | 2 | 3–5 | 6+ | 2+ late per 10k frames | freezes |
+|---|---|---|---|---|---|---|---|
+| A: step 1 as is | 0.90% | 575 | 64 | 91 | 9 | 20.1 | 0 |
+| B: `switch_interval_ms` 1 | 0.78% | 510 | 105 | 23 | 2 | 15.8 | 0 |
+| C: `prefetch_gate` | **0.60%** | 471 | 11 | 7 | 2 | **2.5** | 0 |
+
+The gate removes the frames the render thread spent waiting for the GIL, and
+it costs the prefetch nothing that shows: it parked the thread for 3–6 s per
+run, and the next group was ready at every strip extension in every arm.
+`prefetch_gate` is therefore on by default; `switch_interval_ms` stays an
+off-by-default experiment. What is left is almost all one refresh late, which
+is the per-frame budget (a 6.75 ms p50 blit in a refresh the panel holds at
+83–85 Hz while rendering), not contention.
+
+The runs restart the service, so the hourly sports refresh never fell inside
+one. That refresh is its own case: about twenty ESPN chunk-fetch threads at
+once, which the gate does not cover (it gates only the prefetch thread).
+
+## The problem
+
+Vegas mode builds its ticker from every plugin's content. Most of that work
+already happens on a background prefetch thread
+(`RenderPipeline.start_prefetch`). But any plugin whose content needs the
+**shared display canvas** is deferred to the render thread
+(`RenderPipeline.drain_deferred`), one plugin every two seconds. The code's
+own comments put each of those at 40–600 ms, and the render thread presents no
+frames while one runs.
+
+On hdpi (Pi 4, 512×64) most plugins take that path: geochron, tide-display,
+news, hockey-scoreboard, ledmatrix-stocks, incoming-packages, clock-simple,
+countdown, birdnet-go, ledmatrix-music and odds-ticker. They arrive in bursts
+("Whole group deferred; strip will extend as it drains") every minute or so,
+12 fetches in five minutes. That is the "occasional pause" a viewer sees.
+
+An 8-minute soak (`scripts/frame_soak.py --preview`) of the #628 build on
+hdpi:
+
+| late by | frames |
+|---|---|
+| 1 refresh | 238 |
+| 2 | 32 |
+| 3–5 | 30 |
+| 6+ | 5 |
+| freezes ≥ 250 ms | 2 (0.97 s total) |
+
+The 3+ rows and the freezes are the pauses. The single-refresh row is a
+separate problem: the blit is 6 ms of a 10 ms refresh, so there is little
+slack. It is covered under *What this does not fix*.
+
+## Why a plugin is canvas-bound
+
+The plugin-facing canvas is a set of shared attributes on `DisplayManager`:
+`image`, `draw`, `matrix`, and the `width`/`height` properties that read from
+`matrix`. Three adapter paths (`src/vegas_mode/plugin_adapter.py`) need them,
+and each returns `None` under `offscreen_only=True` so the plugin is queued for
+the render thread:
+
+1. **Display capture** (`_capture_display_content`): clear the canvas, call
+   `plugin.display()`, copy `display_manager.image`. Used by any plugin
+   without `get_vegas_content()` or a populated `scroll_helper`.
+2. **Scroll-content generation** (`_trigger_scroll_content_generation`): a
+   ticker plugin whose `scroll_helper.cached_image` is empty is made to build
+   it by calling `display(force_clear=True)` or `_create_scrolling_display()`.
+   Both draw on the canvas.
+3. **Narrowed rendering** (`DisplayManager.render_size`): swaps the shared
+   `matrix`, `image` and `draw` for a narrower set so the plugin lays out for
+   `render_width_pct`. The render thread would see the swap mid-frame.
+
+The render thread keeps the canvas coherent only because nothing else touches
+it at the same time. A background thread can't use it.
+
+## The design: a per-thread render target
+
+`capture_mode()` is already per-thread (#423 made its state a
+`threading.local`, so a background capture no longer suppresses the render
+loop's pushes). The same move applies to the canvas itself:
+
+```python
+with display_manager.offscreen(width=None, height=None) as surface:
+    plugin.display(force_clear=True)
+    content = surface.image.copy()
+```
+
+For the **calling thread only**, inside the block:
+
+| accessor | resolves to |
+|---|---|
+| `display_manager.image`, `.draw` | the surface's own image and draw: a fresh black canvas, `fontmode = "1"` |
+| `display_manager.matrix` | a logical proxy reporting the surface size, so `width`/`height` and plugins that read `matrix.width` follow it. Hardware calls through it (`SetImage`, `SwapOnVSync`, `Clear`, brightness writes) are inert. |
+| `update_display()`, `clear()` | canvas-only: the block implies capture mode, which is already per-thread |
+| `set_scrolling_state()`, `set_frame_hold()` | no-ops, so a plugin's `display()` cannot re-pace the live scroll. Today it can, when it is captured on the render thread. |
+
+Every other thread sees the real canvas, unchanged. The render loop in
+particular keeps presenting while a plugin draws elsewhere.
+
+### Implementation sketch
+
+- `image`, `draw` and `matrix` become properties over `_image`, `_draw` and
+  `_matrix`, plus a thread-local current surface. The getter returns the
+  surface's value when the calling thread has one, else the shared one; setters
+  mirror that. That costs about 0.1 µs per access, and `update_display()` reads
+  each a handful of times per frame. Every existing `self.image = ...` in
+  `DisplayManager` (`clear()`, setup, fallback) keeps working and becomes
+  thread-correct for free.
+- `render_size()` is rebuilt on `offscreen()`: it creates or narrows the
+  calling thread's surface instead of swapping shared state.
+- `offscreen()` nests and always restores on exit, including when the plugin
+  raises.
+- `VisualDisplayManager` (the plugin test harness) gets the same method, for
+  parity.
+
+### Adapter changes
+
+- `get_content(offscreen_only=True)` stops returning `None` for the three
+  paths above. Each runs inside `display_manager.offscreen(render_width)`.
+- `_capture_display_content` and `_trigger_scroll_content_generation` drop
+  their "copy the shared image, restore it afterwards" bookkeeping, since the
+  shared image is never touched.
+- **Take the plugin's lock.** `PluginManager.get_plugin_lock()` keeps
+  `update()` and `display()` mutually exclusive in normal rotation, but Vegas
+  never takes it, so today's render-thread captures already race
+  `update()`. Off the render thread the adapter can afford to wait: blocking
+  acquire with a timeout (proposed 2 s). On timeout it keeps the cached segment
+  and tries again next group.
+- `drain_deferred()` and the deferred queue are deleted. The only render-thread
+  fetch left is the inline fallback when no prepared group is ready, which in
+  practice is the first extension. Prefetching at start removes that too.
+
+## Keeping live content fresh
+
+Offscreen rendering is also what makes fresh sports scores possible. Today a
+plugin's segment is drawn when its group is prefetched, and the strip carries
+7,000–10,000 px of content ahead of the viewport (hdpi logs: "7153px still
+ahead", "9842px ahead"). At ~100 px/s, a score drawn now reaches the screen
+70–100 seconds later. When a plugin reports new data, Vegas only drops its
+cache (`invalidate_pending_updates`), so the change is drawn on the plugin's
+*next* turn, several minutes later. A segment already in the strip scrolls by
+with the data it was drawn with.
+
+That was the right trade while every redraw of a canvas-bound plugin stalled
+the scroll. Off the render thread a redraw costs the scroll nothing, so the
+strip can afford three things.
+
+### 1. Refresh at the gate
+
+Before a segment enters the viewport, check whether its plugin has updated
+since the segment was drawn. If it has, redraw it offscreen and replace it
+while it is still out of sight. Width changes are fine here, because
+everything from that segment onward is still invisible.
+
+The gate sits `lead` pixels ahead of the viewport's right edge:
+`lead = max(one screen, speed × (render time + margin))`. The render time is
+the plugin's own, measured on each render (sports cards take the longest,
+hundreds of ms up to seconds per the prefetch notes). A plugin whose render
+does not finish before its segment reaches the viewport keeps the old segment.
+The scroll never waits for it.
+
+Content is then at most `lead / speed` seconds old when it appears, a few
+seconds instead of minutes, without changing how far ahead the rotation
+fetches.
+
+### 2. Replace ahead of the screen
+
+When a plugin reports new data (the Vegas update tick already names them), any
+of its segments that are **anywhere ahead of the viewport** are redrawn and
+replaced straight away, not only at the gate. That covers the long stretch of
+strip between prefetch and the gate.
+
+### 3. Update on screen
+
+A segment that is already **visible** is patched in place when the redrawn
+version has the same geometry: the same total width, and the same width for
+each card (a sports plugin returns one image per game, joined with
+`intra_plugin_gap`). Scoreboard cards keep a fixed layout, so a score change
+patches in and the digits update as the card scrolls past. The patch is a
+pixel copy of one card (a 150×64 card is ~29 KB) applied by the render thread
+between frames, so a frame never shows half of a patch.
+
+When the geometry differs (a game added or dropped, a card that grew), the
+visible part cannot change without a jump. Only the cards not yet on screen
+are replaced, and only if the geometry up to that point is unchanged. Otherwise
+the segment keeps its snapshot until it has scrolled off.
+
+### Avoiding wasted work
+
+- **Change detection.** `run_scheduled_updates_with_changes()` names a plugin
+  whenever its `update()` ran, not when its data changed. On hdpi
+  `clock-simple` and `ledmatrix-music` are named on every 4-second tick. A
+  redraw whose pixels hash the same as the segment's is discarded without a
+  swap.
+- **Redraw on real updates only.** Vegas makes no API calls. Each plugin
+  fetches on its own schedule, and a redraw is triggered only when the
+  plugin's `update()` has run since its segment was drawn. On hdpi live
+  football, baseball and hockey poll every 30 s (live odds every 60 s,
+  everything else hourly), so a live sports card is redrawn once per poll.
+- **Floor.** A plugin is redrawn at most once per
+  `vegas_scroll.refresh_min_interval` (proposed 10 s), and never while its
+  previous redraw is still running. The floor never holds back a sports card
+  polling every 30 s. It exists for chatty plugins: `clock-simple` updates
+  every second and `ledmatrix-music` polls every 2 s.
+- **One worker.** Redraws go through the same background worker as prefetch,
+  one plugin at a time at `nice 10`, under the plugin's lock.
+
+Data freshness is still bounded by each plugin's own fetch interval (how often
+it polls live scores). Drawing faster cannot beat the data source.
+
+### The strip becomes a list of segments
+
+All three need the strip to be replaceable by segment. Today it is one
+image (`ScrollHelper.cached_array`, 8,000–20,000 px wide, 1.5–3.8 MB), and
+`append_content()` rebuilds the whole thing on the render thread for every
+appended block. That is also a pause source.
+
+Proposed `SegmentStrip`, used by Vegas in place of the single image:
+
+- an ordered list of segments: plugin id, card boundaries, a pixel array, the
+  render time, and the plugin data version it was drawn from, plus its
+  x-offset in the strip;
+- `visible(x, width)` assembles the viewport by slicing across at most a few
+  segments: the same ~100 KB copy per frame that slicing the single image
+  costs today;
+- append and trim become O(block) list operations, not a copy of the strip;
+- replace swaps one list entry and shifts the offsets of the segments after it
+  (dozens at most). A same-geometry patch copies pixels into the existing array.
+
+Every mutation is prepared off the render thread and applied by the render
+thread at a frame boundary, so the strip the render loop reads is never
+half-changed.
+
+### Multi-display sync
+
+The follower renders from its own copy of the strip, offset from the leader's
+scroll position. Today the leader sends that copy whole, and only in
+`start_new_cycle()` (`send_scroll_image`), plus the scroll position every
+frame. Continuous scroll, the default, extends and trims the strip without
+starting a new cycle, and nothing sends those changes. From reading the code,
+the follower therefore probably falls out of step after the first extension
+already, before any of this design. That is untested; it needs a two-Pi rig.
+
+With a segment strip, keeping the follower identical becomes **replaying the
+leader's operations**:
+
+- Every strip mutation (append, trim, replace, patch) is one operation in
+  strip coordinates. The leader applies it and sends the same operation to the
+  follower over the existing TCP channel. Segments are small: a card is ~29 KB
+  raw and compresses well.
+- Operations on off-screen segments apply on arrival. A patch to a segment
+  that is on either panel carries an *apply at scroll position X* stamp a
+  couple of hundred milliseconds ahead. Both sides apply it when their scroll
+  position passes X, so both panels change on the same frame, within the
+  existing position-sync jitter.
+- Each operation carries a sequence number. A follower that sees a gap (a
+  reconnect, a dropped message) asks for a full snapshot, which is today's
+  `send_scroll_image` path.
+
+That also fixes the probable continuous-mode gap as a side effect, since
+appends and trims become operations too. Until it is in place, fresh-content
+updates are disabled while sync is active.
+
+## Risks, and what was checked
+
+1. **Plugins holding their own reference to the shared `draw` or `image`.**
+   They would keep drawing into the shared canvas, and routing by thread can't
+   redirect them. A grep of the 49 plugins installed on hdpi found none storing
+   `display_manager.draw` or `.image` in an attribute (a pattern search, so
+   indirect aliasing would slip past it). A plugin that did would
+   draw into an image nobody displays, which trims to a blank segment. That is
+   not corruption, and it is no worse than today.
+2. **Plugins calling the matrix directly.** None in the audit. Inside
+   `offscreen()` the proxy makes it inert anyway.
+3. **Font thread-safety.** `FontManager` shares font objects across plugins.
+   Measured on Pillow 12.3, two threads rendering text take 1.94× as long as
+   one, so text rendering holds the GIL and FreeType is never entered
+   concurrently. Re-check if Pillow changes that.
+4. **Plugin thread-safety.** `display()` moves to the prefetch thread. The
+   plugin lock makes it exclusive with `update()`, which is more protection
+   than it has today. Threads a plugin starts itself are not covered, as today.
+5. **The GIL.** Moving 40–600 ms of plugin rendering off the render thread
+   removes the pauses, but the work still needs the GIL. Pillow drawing holds
+   it, and a waiting thread only gets it back after the switch interval
+   (default 5 ms). Expect some single-refresh late frames while a prefetch
+   runs. Measure with the soak. A render process separate from plugin work
+   is the structural answer (the "native presenter" step). Two experiments
+   get most of the way first (results under Status, above):
+   - `vegas_scroll.switch_interval_ms` lowers the switch interval for a Vegas
+     run (1 ms is the obvious try), so the render thread waits at most that
+     long behind bytecode. It does nothing for a C call that keeps the GIL.
+   - `vegas_scroll.prefetch_gate` (`src/common/render_gate.py`) lets the
+     prefetch thread run Python only while the render thread is blocked in
+     `SwapOnVSync`, up to just before the refresh the swap returns on, and
+     parks it the rest of the time. That covers C calls too, since the gate is
+     checked before each one starts. It never parks the thread while it holds
+     a lock the render thread takes, and never for more than 50 ms. It needs
+     the rebuilt binding, which releases the GIL during the swap. On by
+     default.
+
+## What this does not fix
+
+- **The blit.** Copying a 512×64 frame into the matrix (`SetImage`) is ~6 ms at
+  8 PWM bits on a Pi 4, leaving ~4 ms of slack per refresh. That is the main
+  source of the single-refresh late frames. Holding frames for two refreshes
+  (≈50 px/s) doubles the budget. Cutting the blit itself is the native-presenter
+  step.
+- **Live refreshes pushed from `update()`.** Some sports plugins call
+  `display()` and `update_display()` from inside `update()`, which runs on the
+  update worker and can push to the panel mid-Vegas. That is a separate
+  hazard. `offscreen()` gives a tool for it (run the update worker offscreen
+  while Vegas owns the panel), but it is out of scope here.
+
+## Test plan
+
+- **Unit, `DisplayManager`:** one thread inside `offscreen()` draws while
+  another reads `image`/`draw`/`matrix`/`width`/`height` and sees the real
+  canvas. Also: `update_display()` and `set_scrolling_state()` are inert inside;
+  `render_size()` narrows only the calling thread; nesting and exceptions
+  restore state.
+- **Unit, adapter:** a stub display-capture plugin and a stub scroll-helper
+  plugin both return content with `offscreen_only=True`, and nothing is queued
+  for the render thread. The plugin lock is taken, and a timeout keeps the cached
+  segment.
+- **Emulator integration:** a stub canvas-bound plugin whose `display()` sleeps
+  300 ms. The Vegas render loop never goes a frame without presenting (frame
+  timing recorder: zero freezes).
+- **Unit, `SegmentStrip`:** the viewport assembled across segment boundaries
+  matches slicing one concatenated image, pixel for pixel. Append, trim,
+  replace-ahead and same-geometry patch each leave every other column
+  unchanged. A geometry-changing patch of a visible segment is refused.
+- **Freshness:** a stub sports plugin whose score changes every second. The
+  score on screen is never older than `lead / speed` plus the plugin's fetch
+  interval. A visible card's digits change without the frame-timing recorder
+  seeing a late frame. An unchanged redraw is discarded.
+- **Hardware:** an hdpi soak, A/B against the #628 build, alternating order.
+  Targets: no freezes, an empty 6+ bucket, the 3–5 bucket near zero, and the late
+  rate below 0.66%. Plus, for freshness: log each segment's age when it enters
+  the viewport, and compare the median and max before and after.
+
+## Rollout
+
+Three changes, each soaked on hdpi before the next:
+
+1. **Offscreen rendering:** `offscreen()`, the adapter on the prefetch thread,
+   and the plugin lock. Removes the render-thread pauses.
+2. **`SegmentStrip`:** Vegas's strip becomes a list of segments. Removes the
+   whole-strip copy on append. No visible behaviour change.
+3. **Fresh content:** refresh at the gate, replace ahead, patch on screen,
+   with change detection and the rate limit.
+
+`display.vegas_scroll.offscreen_prefetch` (default `true`) restores today's
+deferred path when `false`, and `display.vegas_scroll.live_refresh` (default
+`true`) turns off step 3. Keep both for one release, then delete the old paths.
+
+## Open questions
+
+1. Keep the kill switch, or ship without one?
+2. Plugin lock timeout: skip the plugin and keep its cached segment (proposed),
+   or wait longer?
+3. `refresh_min_interval`: 10 s proposed. It only limits chatty plugins;
+   live sports are redrawn once per 30 s poll regardless.
+4. Multi-display sync: is there a two-Pi rig to test on? Operation replay is
+   proposed as part of the segment strip (step 2), with fresh content
+   disabled under sync until it has been verified on real hardware.

+
+`ledmatrix-web.service` deliberately has no `CacheDirectory=`: systemd would
+re-own `/var/cache/ledmatrix` to the web user and its primary group, and the

+If `/var/cache/ledmatrix` is not usable, `CacheManager` falls back to
+`~/.ledmatrix_cache`, `/opt/ledmatrix/cache` or a temp directory
+([`src/cache_manager.py`](../src/cache_manager.py)). The two services then
+may not share a cache, and the web UI shows stale or empty display status,
+on-demand state and plugin health. Fix the directory rather than living
+with the fallback.
+
+## sudo rules
+
+### `/etc/sudoers.d/ledmatrix_web`
+
+Generated by `web_sudoers_rules()` in
+[`scripts/install/lib_sudoers.sh`](../scripts/install/lib_sudoers.sh), the
+only place these rules are defined. Installed by the installer and by
+[`configure_web_sudo.sh`](../scripts/install/configure_web_sudo.sh), both of
+which check them with `visudo -c` first. The web user may run, without a
+password:
+
+- `reboot`, `poweroff`
+- `systemctl start|stop|restart|enable|disable|status ledmatrix.service`,
+  `systemctl is-active ledmatrix[.service]`
+- `systemctl start|stop|restart ledmatrix-web.service`
+- `bash <project>/scripts/fix_perms/safe_plugin_rm.sh *` — removes a
+  directory only if it resolves to a child of `plugin-repos/` or `plugins/`
+- `bash <project>/scripts/fix_perms/safe_pip_install.sh *` — installs a
+  `requirements.txt` only if it is the project's own or one under
+  `plugin-repos/` or `plugins/`, so the root display service can import the
+  packages
+- `journalctl -u ledmatrix.service *`, `-u ledmatrix *`, `-t ledmatrix *`,
+  tagged `NOEXEC`: journalctl opens a pager on a terminal, and a shell
+  escape from that pager would be a root shell
+
+### `/etc/sudoers.d/ledmatrix_wifi`
+
+Written by
+[`scripts/install/configure_wifi_permissions.sh`](../scripts/install/configure_wifi_permissions.sh)
+(run as the web user; the installer calls it). It refuses to grant a binary
+that is not root-owned or is group/world-writable. The rules cover:
+
+- `nmcli device wifi connect|disconnect *`, `nmcli device connect|disconnect *`,
+  `nmcli radio wifi on|off`
+- `systemctl start|stop|restart hostapd`, `... dnsmasq`,
+  `systemctl restart NetworkManager`
+- `sysctl -w net.ipv4.ip_forward=0|1`
+- `nft add|delete table ip ledmatrix`
+- `rfkill unblock wifi`
+- `mkdir -p /etc/NetworkManager/dnsmasq-shared.d`
+- `cp` of `/tmp/hostapd.conf` and `/tmp/dnsmasq.conf` to their fixed
+  destinations, and `rm -f /etc/dnsmasq.d/ledmatrix-captive.conf`
+- `cp /tmp/ledmatrix-nm-dnsmasq.conf` to
+  `/etc/NetworkManager/dnsmasq-shared.d/ledmatrix-captive.conf`, and
+  `rm -f` of that file
+
+**`iptables` is deliberately not granted.** The captive portal's rules are
+built from the interface name and port, so a rule covering them would need a
+trailing wildcard, and `iptables --modprobe=<path>` runs `<path>` as root: a
+wildcard grant is a root shell for the web user. Doing it safely needs a
+wrapper script that builds the rules itself, like `safe_plugin_rm.sh`. On a
+stock Raspberry Pi OS image the default user's blanket `NOPASSWD` rule
+(`/etc/sudoers.d/010_pi-nopasswd`) hides this gap.
+
+### polkit
+
+The same script installs `/etc/polkit-1/rules.d/10-ledmatrix-wifi.rules`,
+which lets the web user perform any `org.freedesktop.NetworkManager.*`
+action without authentication.
+
+## Repair scripts
+
+In [`scripts/fix_perms/`](../scripts/fix_perms/). Run them from the project
+directory.
+
+| Script | Run as | What it does | Notes |
+|---|---|---|---|
+| `fix_plugin_permissions.sh` | `sudo` | `plugins/` and `plugin-repos/` to `root:<user>`, dirs `2775`, files `664`; makes a `700` home directory `755` so root can traverse it | Safe. Group-writable, so the web user keeps write access |
+| `fix_assets_permissions.sh` | `sudo` | `assets/` to `<user>:<group>`, mode `777` recursively | Works, but looser than the installer's `755`/`644` |
+| `fix_cache_permissions.sh` | `sudo` | Runs [`setup_cache.sh`](../scripts/install/setup_cache.sh) for `/var/cache/ledmatrix` (`root:ledmatrix`, `2775`, files `660`), then makes `~/.ledmatrix_cache` (the fallback cache) `<user>:<group>` mode `777` | Safe. The `~/.ledmatrix_cache` mode is still `777` |
+| `fix_web_permissions.sh` | the web user, **without** `sudo` | Resets project file ownership for the web user (it calls `sudo` itself), then makes `safe_plugin_rm.sh` and `safe_pip_install.sh` `root:root` `755` again and restores `config_secrets.json` to its owner, group `ledmatrix`, mode `640` | Refuses to run as root. It does not write sudoers rules |
+| `safe_plugin_rm.sh`, `safe_pip_install.sh` | — | Called by the web interface through sudo | Not for manual use |
+
+To reinstall the sudoers rules, run
+`./scripts/install/configure_web_sudo.sh` (web rules) or
+`./scripts/install/configure_wifi_permissions.sh` (WiFi rules and polkit) as
+the web user, not with `sudo`.
+
+After any of these, restart both services:
+
+```bash
+sudo systemctl restart ledmatrix.service ledmatrix-web.service
+```
+
+## Checking
+
+```bash
+ls -ld /var/cache/ledmatrix          # drwxrwsr-x root ledmatrix
+stat -c '%U:%G %a %n' config/config.json config/config_secrets.json
+id                                   # web user should list ledmatrix
+sudo -l                              # lists the NOPASSWD rules

+## Manifest Required Fields
+
+Three parts of core check `manifest.json`, each for a different set of
+fields:
+
+| Check | Fields | What happens when one is missing |
+|---|---|---|
+| JSON schema, [`schema/manifest_schema.json`](../schema/manifest_schema.json) | `id`, `name`, `version`, `author`, `entry_point`, `class_name`, `compatible_versions` | Install from URL logs a warning (`PluginStoreManager._validate_manifest_schema()`); nothing is refused |
+| Plugin Store install, [`src/plugin_system/store_install.py`](../src/plugin_system/store_install.py) | `id`, `name`, `class_name`, `display_modes` | Install is refused. A registry install first tries to detect a missing `class_name` from the entry-point file |
+| Plugin loader, [`src/plugin_system/plugin_loader.py`](../src/plugin_system/plugin_loader.py) | `class_name` | The plugin fails to load |
+
+Defaults and other uses:
+
+- `entry_point` defaults to `manager.py`; the store writes the default back
+  into the manifest on install.
+- `compatible_versions` (a list of semver ranges such as `">=2.0.0"`) is how
+  the store decides whether a plugin can run on this core. An install is
+  refused only when the field excludes the running version
+  (`compatibility.check()` in
+  [`src/plugin_system/compatibility.py`](../src/plugin_system/compatibility.py)).
+- `version` is compared with the registry's `latest_version` to decide
+  whether an update is available.
+- If `display_modes` is empty at load time, the display controller uses the
+  plugin id as the only mode.
+
+**Set all eight:** `id`, `name`, `version`, `author`, `entry_point`,
+`class_name`, `display_modes`, `compatible_versions`. That satisfies every
+check. The schema lists the optional fields.
+
+```json

+  "id": "my-plugin",
+  "name": "My Plugin",
+  "version": "1.0.0",

 ### Scrolling State Management
 
 For plugins that implement scrolling content, use these methods to coordinate with the display system.
 
-#### `set_scrolling_state(is_scrolling: bool) -> None`
+#### `set_scrolling_state(is_scrolling: bool, frame_hold: int = 1) -> None`
 
-Mark the display as scrolling or not scrolling. Call when scrolling starts/stops.
+Mark the display as scrolling or not scrolling, and set this scroll's frame
+pacing. Call it when a scroll starts (calling it on every scroll frame is fine)
+and with `False` when it stops.
 
 **Parameters**:
 - `is_scrolling` (bool): True if currently scrolling, False otherwise
+- `frame_hold` (int, default 1): how many panel refreshes each pushed frame is
+  held for (clamped to 1-255; ignored when `is_scrolling` is False, which
+  resets it to 1). Pass the `frame_hold` of the settings
+  `src.common.scroll_config.configure()` returned. Added in core 3.4.0.
+
+**Why `frame_hold` matters**: `scroll_config.configure()` snaps the speed to
+one the panel can show in whole pixels and sets the `ScrollHelper` to advance a
+fixed number of pixels on every presented frame -- no clock is consulted. The
+panel presents frames at its refresh rate divided by the hold, so the hold is
+part of the speed. Omit it and a 50 px/s scroll (1px every 2nd refresh on a
+100 Hz panel) runs at 100 px/s. The hold is not applied by `configure()`
+because it must not outlive the scroll: plugins share one display manager.
 
 **Example**:
 ```python
+from src.common import scroll_config
+from src.common.scroll_helper import ScrollHelper
+
+def __init__(self, *args, **kwargs):
+    super().__init__(*args, **kwargs)
+    self.scroll_helper = ScrollHelper(
+        self.display_manager.width, self.display_manager.height, self.logger)
+    # ...later, hand it content with self.scroll_helper.set_scrolling_image(img)
+    self.scroll_settings = scroll_config.configure(
+        self.scroll_helper,
+        plugin_config=self.config,
+        global_config=self.global_config,
+        display_manager=self.display_manager,
+        plugin_logger=self.logger,
+    )
+
 def display(self, force_clear=False):
-    self.display_manager.set_scrolling_state(True)
-    # Scroll content...
-    self.display_manager.set_scrolling_state(False)
+    self.display_manager.set_scrolling_state(
+        True, frame_hold=self.scroll_settings.frame_hold)
+    self.scroll_helper.update_scroll_position()
+    self.display_manager.image = self.scroll_helper.get_visible_portion()
+    self.display_manager.update_display()
+    if self.scroll_helper.is_scroll_complete():
+        self.display_manager.set_scrolling_state(False)
 ```
 
+Don't pace the loop with `time.sleep()`: `update_display()` blocks on the
+panel's vsync, which is what paces a scroll. See `docs/SCROLL_PERFORMANCE.md`
+for choosing a speed.

 # Plugin Configuration Tabs
 
-> **Status note:** this doc was written during the rollout of the
-> per-plugin configuration tab feature. The feature itself is shipped
-> and working in the current v3 web interface, but a few file paths
-> in the "Implementation Details" section below still reference the
-> pre-v3 file layout (`web_interface_v2.py`, `templates/index_v2.html`).
-> The current implementation lives in `web_interface/app.py`,
-> `web_interface/blueprints/api_v3.py`, and `web_interface/templates/v3/`.
-> The user-facing description (Overview, Features, Form Generation
-> Process) is still accurate.

-To enable automatic configuration tab generation, your plugin must:
+Every installed plugin gets a tab. To get a generated form in it, include a
+`config_schema.json` file in the plugin's directory. The name is fixed: the

-New Functions:
-- `generatePluginTabs(plugins)` - Creates tab buttons and content for each plugin
-- `generatePluginConfigForm(plugin)` - Generates HTML form from JSON Schema
-- `savePluginConfiguration(pluginId)` - Saves form data to backend
-- `resetPluginConfig(pluginId)` - Resets all settings to defaults

+1. The web UI loads installed plugins via `/api/v3/plugins/installed` and adds

+2. Opening a tab loads `/v3/partials/plugin-config/<plugin_id>`

+   through `SchemaManager` and its current values from `config.json`
+3. `web_interface/templates/v3/partials/plugin_config.html` renders the form
+   from the schema (widgets named by `x-widget` are rendered by the scripts in
+   `web_interface/static/v3/js/widgets/`)
+4. **Save Configuration** posts the form to `/api/v3/plugins/config`
+   (`web_interface/blueprints/api_v3/plugin_config.py`), which validates it against
+   the schema, writes `config.json` (secret fields go to

 ## Troubleshooting
 
 ### Plugin Tab Not Appearing
 
-- Ensure `config_schema.json` exists in plugin directory
-- Verify `config_schema` field in `manifest.json`
+- Check that the plugin is installed and appears in the **Plugin Manager** tab
 - Check browser console for errors
-- Try refreshing plugins (Plugins tab → Refresh button)
+- Reload the page
 
 ### Form Not Generating Correctly

-- **Visual Validation**: Real-time validation feedback as user types
-- **Color Pickers**: Special input for RGB/color array types
-- **File Uploads**: Support for image/asset uploads
-- **Import/Export**: Save and share plugin configurations
-- **Presets**: Quick-switch between saved configurations
-- **Documentation Links**: Link schema fields to plugin documentation

+`POST /api/v3/plugins/config/reset` replaces the plugin's section with the
+schema defaults (keeping secrets unless `preserve_secrets` is false).
 
 ## Key Design Decisions
 
-### 1. Dynamic Tab Generation
+### 1. Server-side rendered forms
 
-**Why**: Plugins are installed/uninstalled dynamically  
-**How**: JavaScript creates/removes tab elements on plugin list refresh  
-**Benefit**: No server-side template rendering needed
+**Why**: One renderer for every plugin, no per-plugin frontend code
+**How**: Jinja macros in `partials/plugin_config.html` walk the schema
+**Benefit**: The settings search index is built from the same rendered HTML
+(`/v3/settings/search-index`)
 
-### 2. JSON Schema as Source of Truth
+### 2. JSON Schema as source of truth
 
-**Why**: Standard, well-documented, validation-ready  
-**How**: Frontend interprets schema to generate forms  
-**Benefit**: Plugin developers use familiar format
+**Why**: Standard, well-documented, validation-ready
+**How**: The same schema drives the form, the defaults and server-side validation
+**Benefit**: Plugin developers use a familiar format
 
-### 3. Individual Config Updates
+### 3. Whole-form saves that merge
 
-**Why**: Simplifies backend API  
-**How**: Each field saved separately via `/api/v3/plugins/config`  
-**Benefit**: Atomic updates, easier error handling
+**Why**: A partial form (or a field the form doesn't show) must not wipe
+stored values
+**How**: The handler starts from the stored section and merges what was posted
+**Benefit**: One request per save, atomic write
 
-### 4. Type Conversion in Frontend
+### 4. Secrets kept out of config.json
 
-**Why**: HTML forms only return strings  
-**How**: JavaScript converts based on schema type before sending  
-**Benefit**: Backend receives correctly-typed values
-
-### 5. No Nested Objects
-
-**Why**: Keeps UI simple  
-**How**: Only flat property structures supported  
-**Benefit**: Easy form generation, clear to users
+**Why**: `config.json` is shown in the raw editor and returned by the API
+**How**: `"x-secret": true` fields go to `config_secrets.json`, which is
+deep-merged back into the plugin's config at load time
+**Benefit**: Plugins read secrets with plain `config.get(...)`
 
 ## Extension Points
 
-### Adding New Input Types
+### Custom input widgets
 
-Location: `generatePluginConfigForm()` in `index_v2.html`
+Set `"x-widget": "<name>"` on a property. Core widgets are in
+`web_interface/static/v3/js/widgets/`; a plugin can ship its own widget
+script, served from `/static/plugin-widgets/<plugin_id>/<name>.js`. See the
+[widget guide](../web_interface/static/v3/js/widgets/README.md).
 
-```javascript
-if (type === 'your-new-type') {
-    formHTML += `
-        <!-- Your custom input HTML -->
-    `;
-}
-```
+### Custom actions
 
-### Custom Validation
+Buttons that run plugin scripts are declared in the manifest's
+`web_ui_actions`. See [PLUGIN_WEB_UI_ACTIONS.md](PLUGIN_WEB_UI_ACTIONS.md).
 
-Location: `savePluginConfiguration()` in `index_v2.html`
+### Reacting to changes
 
-```javascript
-// Add validation before sending
-if (!validateCustomConstraint(value, propSchema)) {
-    throw new Error('Validation failed');
-}
-```
+Implement `on_config_change(new_config)` in the plugin (see
+[PLUGIN_API_REFERENCE.md](PLUGIN_API_REFERENCE.md)).
 
-### Backend Hook
+## Where to Look
 
-Location: `api_plugin_config()` in `web_interface_v2.py`
-
-```python
-# Add custom logic before saving
-if plugin_id == 'special-plugin':
-    value = transform_value(value)
-```
-
-## Performance Considerations
-
-### Frontend
-
-- **Tab Generation**: O(n) where n = number of plugins (typically < 20)
-- **Form Generation**: O(m) where m = number of config properties (typically < 10)
-- **Memory**: Each plugin tab ~5KB HTML
-- **Total Impact**: Negligible for typical use cases
-
-### Backend
-
-- **Schema Loading**: Cached after first load
-- **Config Updates**: Single file write (atomic)
-- **API Calls**: One per config field on save (sequential)
-- **Optimization**: Could batch updates in single API call
-
-## Security Considerations
-
-1. **Input Validation**: Schema constraints enforced client-side (UX) and should be enforced server-side
-2. **Path Traversal**: Plugin paths validated against known plugin directory
-3. **XSS**: All user inputs escaped before rendering in HTML
-4. **CSRF**: Flask CSRF tokens should be used in production
-5. **File Permissions**: config.json requires write access
+| Concern | File |
+|---------|------|
+| Tab partial loader | `web_interface/blueprints/pages_v3.py` (`_load_plugin_config_partial`) |
+| Form template and field macros | `web_interface/templates/v3/partials/plugin_config.html` |
+| Save / get / schema / reset handlers | `web_interface/blueprints/api_v3/plugin_config.py` |
+| Schema loading, defaults, validation | `src/plugin_system/schema_manager.py` |
+| Secret masking and splitting | `src/web_interface/secret_helpers.py` |
+| Widgets | `web_interface/static/v3/js/widgets/` |
 
 ## Error Handling
 
-### Frontend
-
-- Network errors: Show notification, don't crash
-- Schema errors: Graceful fallback to no config tab
-- Type errors: Log to console, continue processing other fields
-
-### Backend
-
-- Invalid plugin_id: 400 Bad Request
-- Schema not found: Return null, frontend handles gracefully
-- Config save error: 500 Internal Server Error with message
-
-## Testing Strategy
-
-### Unit Tests
-
-- `generatePluginConfigForm()` for each schema type
-- Type conversion logic in `savePluginConfiguration()`
-- Backend schema loading logic
-
-### Integration Tests
-
-- Full save flow: form → API → config.json
-- Tab generation from API response
-- Reset to defaults
-
-### E2E Tests
-
-- Install plugin → verify tab appears
-- Configure plugin → verify config saved
-- Uninstall plugin → verify tab removed
-
-## Monitoring
-
-### Frontend Metrics
-
-- Time to generate tabs
-- Form submission success rate
-- User interactions (configure, save, reset)
-
-### Backend Metrics
-
-- API response times
-- Config update success rate
-- Schema loading errors
-
-### User Feedback
-
-- Are users finding the configuration interface?
-- Are validation errors clear?
-- Are default values sensible?
-
-## Future Roadmap
-
-### Phase 2: Enhanced Validation
-- Real-time validation feedback
-- Custom error messages
-- Dependent field validation
-
-### Phase 3: Advanced Inputs
-- Color pickers for RGB arrays
-- File upload for assets
-- Rich text editor for descriptions
-
-### Phase 4: Configuration Management
-- Export/import configurations
-- Configuration presets
-- Version history/rollback
-
-### Phase 5: Developer Tools
-- Schema editor in web UI
-- Live preview while editing schema
-- Validation tester
-

 ## Overview
 
-Plugins can specify custom icons that appear next to their name in the web interface tabs. This makes your plugin instantly recognizable and adds visual polish to the UI.
+A plugin can name an icon for its tab in the web interface's second nav row
+(next to **Plugin Manager**) with the `icon` field in `manifest.json`.
 
-## Icon Types Supported
+`GET /api/v3/plugins/installed` passes the manifest's `icon` through (a
+non-string value comes back as `null`), and a plugin without one gets the
+default puzzle piece.
 
-The system supports three types of icons:
+## Font Awesome classes only
 
-### 1. Font Awesome Icons (Recommended)
+`icon` is used verbatim as the CSS class of an `<i>` element
+(`iconEl.className = plugin.icon || 'fas fa-puzzle-piece'` in
+`web_interface/static/v3/js/app-shell.js` and the same fallback in
+`app-early.js`). So it must be a Font Awesome class string. Emoji, image
+paths and URLs are not supported: they would end up as a meaningless class

-### 2. Emoji Icons (Fun & Simple)
+## Default
 
-Use any emoji character for a colorful, fun icon.
-
-**Example:**
-```json
-{
-  "id": "hello-world",
-  "name": "Hello World",
-  "icon": "👋"
-}
-```
-
-**Popular Emojis:**
-- Time: ⏰ 🕐 ⏱️ ⏲️
-- Weather: ☀️ ⛅ 🌤️ 🌧️ ⛈️ 🌩️ ❄️
-- Sports: ⚽ 🏀 🏈 ⚾ 🎾 🏐
-- Music: 🎵 🎶 🎸 🎹 🎤
-- Money: 💰 💵 💴 💶 💷
-- Calendar: 📅 📆
-- News: 📰 📻 📡
-- Fun: 🎮 🎲 🎯 🎨 🎭
-- Nature: 🌍 🌎 🌏 🌳 🌺 🌸
-- Food: 🍕 🍔 🍟 🍦 ☕ 🍰
-
-### 3. Custom Image URLs (Advanced)
-
-Use a custom image file for ultimate branding.
-
-**Example:**
-```json
-{
-  "id": "my-plugin",
-  "name": "My Plugin",
-  "icon": "/plugins/my-plugin/icon.png"
-}
-```
-
-**Requirements:**
-- Image should be 16x16 to 32x32 pixels
-- Supported formats: PNG, SVG, JPG, GIF
-- Can be a relative path, absolute path, or external URL
-- SVG recommended for best quality at any size
-
-## How to Add an Icon
-
-### Step 1: Choose Your Icon
-
-Decide which type suits your plugin:
-- **Font Awesome**: Professional, consistent with UI
-- **Emoji**: Fun, colorful, no setup needed
-- **Custom Image**: Unique branding, requires image file
-
-### Step 2: Add to manifest.json
-
-Add the `icon` field to your plugin's `manifest.json`:
-
-```json
-{
-  "id": "my-weather-plugin",
-  "name": "Weather Display",
-  "version": "1.0.0",
-  "author": "Your Name",
-  "description": "Shows weather information",
-  "icon": "fas fa-cloud-sun",  // ← Add this line
-  "entry_point": "manager.py",
-  ...
-}
-```
-
-### Step 3: Test Your Plugin
-
-1. Install or update your plugin
-2. Open the web interface
-3. Look for your plugin's tab
-4. The icon should appear next to the plugin name
-
-## Examples
-
-### Weather Plugin
-```json
-{
-  "id": "weather-advanced",
-  "name": "Weather Advanced",
-  "icon": "fas fa-cloud-sun",
-  "description": "Advanced weather display with forecasts"
-}
-```
-**Result:** Tab shows: `☁️ Weather Advanced`
-
-### Clock Plugin
-```json
-{
-  "id": "digital-clock",
-  "name": "Digital Clock",
-  "icon": "⏰",
-  "description": "A beautiful digital clock"
-}
-```
-**Result:** Tab shows: `⏰ Digital Clock`
-
-### Sports Scores Plugin
-```json
-{
-  "id": "sports-scores",
-  "name": "Sports Scores",
-  "icon": "fas fa-trophy",
-  "description": "Live sports scores"
-}
-```
-**Result:** Tab shows: `🏆 Sports Scores`
-
-### Custom Branding
-```json
-{
-  "id": "company-dashboard",
-  "name": "Company Dashboard",
-  "icon": "/plugins/company-dashboard/logo.svg",
-  "description": "Company metrics display"
-}
-```
-**Result:** Tab shows: `[logo] Company Dashboard`
-
-## Best Practices
-
-### 1. Choose Meaningful Icons
-- Icon should relate to plugin functionality
-- Users should understand what the plugin does at a glance
-- Avoid generic icons for specific functionality
-
-### 2. Keep It Simple
-- Simpler icons work better at small sizes
-- Avoid icons with too much detail
-- Test how your icon looks at 16x16 pixels
-
-### 3. Match the UI Style
-- Font Awesome icons match the interface best
-- If using emoji, consider contrast with background
-- Custom images should use similar color schemes
-
-### 4. Consider Accessibility
-- Icons should be recognizable without color
-- Don't rely solely on color to convey meaning
-- The plugin name should be descriptive
-
-### 5. Test on Different Displays
-- Check icon clarity on various screen sizes
-- Ensure emoji render correctly on target devices
-- Custom images should have good contrast
-
-## Icon Categories
-
-Here are recommended icons by plugin category:
-
-### Time & Calendar
-- `fas fa-clock`, `fas fa-calendar`, `fas fa-hourglass`
-- Emoji: ⏰ 📅 ⏱️
-
-### Weather
-- `fas fa-cloud-sun`, `fas fa-temperature-high`, `fas fa-wind`
-- Emoji: ☀️ 🌧️ ⛈️
-
-### Finance & Stocks
-- `fas fa-chart-line`, `fas fa-dollar-sign`, `fas fa-coins`
-- Emoji: 💰 📈 💵
-
-### Sports & Games
-- `fas fa-football-ball`, `fas fa-trophy`, `fas fa-gamepad`
-- Emoji: ⚽ 🏀 🎮
-
-### Entertainment
-- `fas fa-music`, `fas fa-film`, `fas fa-tv`
-- Emoji: 🎵 🎬 📺
-
-### News & Information
-- `fas fa-newspaper`, `fas fa-rss`, `fas fa-info-circle`
-- Emoji: 📰 📡 ℹ️
-
-### Utilities
-- `fas fa-tools`, `fas fa-cog`, `fas fa-wrench`
-- Emoji: 🔧 ⚙️ 🛠️
-
-### Social Media
-- `fab fa-twitter`, `fab fa-facebook`, `fab fa-instagram`
-- Emoji: 📱 💬 📧
+With no `icon` (or an empty one) the tab shows `fas fa-puzzle-piece`.
 
 ## Troubleshooting
 
-### Icon Not Showing
-1. Check that the `icon` field is correctly spelled in `manifest.json`
-2. For Font Awesome icons, verify the class name is correct
-3. For custom images, check that the file path is accessible
-4. Refresh the plugins in the web interface
-5. Check browser console for errors
-
-### Emoji Looks Wrong
-- Some emojis render differently on different platforms
-- Try a different emoji if one doesn't work well
-- Consider using Font Awesome instead for consistency
-
-### Custom Image Not Loading
-- Verify the image file exists in the specified path
-- Check file permissions (should be readable)
-- Try using an absolute path or URL
-- Ensure image format is supported (PNG, SVG, JPG, GIF)
-- Check image dimensions (16x16 to 32x32 recommended)
-
-### Icon Too Large/Small
-- Font Awesome and emoji icons automatically size correctly
-- For custom images, adjust the image file dimensions
-- SVG images scale best
-
-## Default Behavior
-
-If you don't specify an `icon` field in your manifest:
-- The plugin tab will show a default puzzle piece icon: 🧩
-- This is the fallback for all plugins without custom icons
-
-## Technical Details
-
-The icon system works as follows:
-
-1. **Frontend reads manifest**: When plugins load, the web interface reads each plugin's `manifest.json`
-2. **Icon detection**: The `getPluginIcon()` function determines icon type:
-   - Contains `fa-` → Font Awesome icon
-   - 1-4 characters → Emoji
-   - Starts with `http://`, `https://`, or `/` → Custom image
-   - Otherwise → Default puzzle piece
-3. **Rendering**: Icon HTML is generated and inserted into:
-   - Tab button in navigation bar
-   - Configuration page header
-
-## Advanced: Dynamic Icons
-
-Want to change icons programmatically? While not officially supported, you could:
-
-1. Store multiple icon options in your manifest
-2. Use JavaScript to swap icons based on plugin state
-3. Update the manifest dynamically and refresh plugins
-
-**Example (advanced):**
-```json
-{
-  "id": "status-display",
-  "icon": "fas fa-circle",
-  "icon_states": {
-    "active": "fas fa-check-circle",
-    "error": "fas fa-exclamation-circle",
-    "warning": "fas fa-exclamation-triangle"
-  }
-}
-```
+1. Check the class name against the Font Awesome 6 Free gallery; a Pro-only
+   or misspelled class renders as a blank space.
+2. Include the style prefix (`fas`, `far` or `fab`) as well as the icon
+   class.
+3. The manifest is re-read on each plugin list load; reload the page after
+   editing `icon`.

 ## Overview
 
-The LEDMatrix system has smart dependency installation that adapts based on who is running it. This guide explains how it works and potential pitfalls.
+A plugin lists its Python packages in its `requirements.txt`. LEDMatrix
+installs them for you when a plugin is installed, updated or loaded. This
+guide explains where they end up and what to do when a plugin can't import a
+package.
 
-## How It Works
+The rule to remember: **packages must be importable by `ledmatrix.service`,
+which runs as root.** Anything installed only into another user's
+`~/.local/` is invisible to it.
 
-### Execution Context Detection
+## Who Runs What
 
-The plugin manager checks if it's running as root:
-```python
-running_as_root = os.geteuid() == 0
+| Service | Runs as | Set by |
+|---------|---------|--------|
+| `ledmatrix.service` (display) | `root` | `systemd/ledmatrix.service` |
+| `ledmatrix-web.service` (web UI) | the user who ran the installer (e.g. `ledpi`) | `User=__USER__` in `systemd/ledmatrix-web.service`, filled in by `scripts/install/install_service.sh` |
+
+## How Dependencies Get Installed
+
+### 1. Installing or updating a plugin from the web UI
+
+The web interface is not root, so it installs through a narrow sudo helper:
+
+1. `PluginStoreManager._install_dependencies()`
+   (`src/plugin_system/store_install.py`) calls
+   `install_requirements_file()` (`src/common/permission_utils.py`).
+2. That runs `sudo -n bash scripts/fix_perms/safe_pip_install.sh <plugin>/requirements.txt`.
+   The helper checks the path is the project's own `requirements.txt` or a
+   `requirements.txt` under `plugin-repos/` or `plugins/`, then runs
+   `python3 -m pip install --break-system-packages --ignore-installed -r ...`
+   **as root**, so the display service can import the packages.
+3. The sudoers rule that allows this is written by the installer
+   (`first_time_install.sh`) or by `scripts/install/configure_web_sudo.sh`.
+
+If sudo refuses (the rule isn't installed), `install_requirements_file()`
+falls back to installing with the web process's own interpreter, as the web
+user, and prefixes the pip output with a note like:
+
+```
+[Root install unavailable (...); installed for the current process's user only.
+Packages may not be visible to ledmatrix.service if it runs as a different
+user — run scripts/install/configure_web_sudo.sh to fix this.]
 ```
 
-Based on this, it chooses the appropriate installation method:
+Fix it by running `./scripts/install/configure_web_sudo.sh` as the web
+user (not with `sudo`; it asks for your password itself), then
+reinstall the plugin (or use the manual install below).
 
-| Running As | Installation Method | Location | Accessible To |
-|------------|-------------------|----------|---------------|
-| **root** (systemd service) | System-wide (`--break-system-packages`) | `/usr/local/lib/python3.X/dist-packages/` | All users |
-| **ledpi** or other user | User-specific (`--user`) | `~/.local/lib/python3.X/site-packages/` | Only that user |
+The **Reinstall Plugin Deps** button on the web UI's Tools tab goes
+through the same helper for every installed plugin.
+
+### 2. Loading a plugin
+
+When a plugin loads, `PluginLoader.install_dependencies()`
+(`src/plugin_system/plugin_loader.py`) checks its `requirements.txt`. If the
+requirements are already satisfied it does nothing; otherwise it runs
+`python3 -m pip install --break-system-packages -r requirements.txt` with the
+interpreter of the process doing the loading (retrying with
+`--ignore-installed` when a system package without a pip RECORD file is in
+the way).
+
+In `ledmatrix.service` that process is root, so restarting the display
+service installs anything missing system-wide:
+
+```bash
+sudo systemctl restart ledmatrix
+```
+
+If you run `python3 run.py` by hand as a normal user instead, pip cannot
+write to the system site-packages and installs into your `~/.local/`. That
+works for your manual run but not for the service.
 
 ## Common Scenarios
 
-### ✅ Scenario 1: Normal Production Use (Recommended)
+### Installing plugins from the web UI (recommended)
 
-**What:** Services running via systemd
+Use the **Plugin Manager** tab. Dependencies are installed as root through
+the sudo helper and the display service can use them.
+
+### Running the display manually for debugging
 
 ```bash
-sudo systemctl start ledmatrix
-sudo systemctl start ledmatrix-web
+cd ~/LEDMatrix
+sudo python3 run.py        # same user as the service
 ```
 
-- **Runs as:** root (configured in .service files)
-- **Installs to:** System-wide
-- **Result:** ✅ Works perfectly, all dependencies accessible
+Running as your own user works for plugins whose packages are already
+installed system-wide, but any *missing* package lands in `~/.local/`.
 
-### ✅ Scenario 2: Web Interface Plugin Installation
+### A plugin works when run manually but fails in the service
 
-**What:** Installing/enabling plugins via web interface at `http://pi-ip:5000`
+Its packages were installed for your user only. Install them as root (see
+below) and restart the service.
 
-- **Web service runs as:** root (ledmatrix-web.service)
-- **Installs to:** System-wide
-- **Result:** ✅ Works perfectly, systemd service can access them
+## Manual Installation
 
-### ✅ Scenario 3: Manual Testing as ledpi (Read-only)
-
-**What:** Running display manually as ledpi to test/debug
+### All plugins
 
 ```bash
-# As ledpi user
-cd /home/ledpi/LEDMatrix
-python3 run.py
-```
-
-- **Runs as:** ledpi
-- **Can import:** ✅ System-wide packages (installed by root)
-- **Result:** ✅ Works! Can use existing plugins with root-installed dependencies
-
-### ⚠️ Scenario 4: Manual Plugin Installation as ledpi (Problematic)
-
-**What:** Enabling a NEW plugin and running manually as ledpi
-
-```bash
-# As ledpi user
-cd /home/ledpi/LEDMatrix
-# Edit config to enable new plugin
-nano config/config.json
-# Run display - will try to install new plugin dependencies
-python3 run.py
-```
-
-**What Happens:**
-1. Plugin manager runs as `ledpi`
-2. Installs dependencies with `--user` flag
-3. Dependencies go to `~/.local/lib/python3.X/site-packages/`
-4. ⚠️ **Warning logged:** "Installing plugin dependencies for current user (not root)"
-
-**Problem:**
-- When systemd service restarts (as root), it **can't see** `~/.local/` packages
-- Plugin will fail to load for the systemd service
-
-**Solution:**
-After testing, restart the service to install dependencies system-wide:
-```bash
+sudo ~/LEDMatrix/scripts/install_plugin_dependencies.sh
 sudo systemctl restart ledmatrix
 ```
 
-## Best Practices
+The script installs every `requirements.txt` found in the plugins directory
+configured by `plugin_system.plugins_directory` in `config/config.json`
+(default `plugin-repos/`). Run it with `sudo` so the packages are installed
+system-wide.
 
-### For Production/Normal Use
+### One plugin
 
-1. **Always use the web interface** to install/enable plugins
-2. **Or restart the systemd service** after config changes:
-   ```bash
-   sudo systemctl restart ledmatrix
-   ```
-
-### For Development/Testing
-
-1. **Read existing plugins:** Safe to run as `ledpi` - can import system packages
-2. **Test new plugins:** Use sudo or restart service to install dependencies:
-   ```bash
-   # Option 1: Run as root
-   sudo python3 run.py
-   
-   # Option 2: Install deps manually
-   sudo pip3 install --break-system-packages -r plugins/my-plugin/requirements.txt
-   python3 run.py
-   
-   # Option 3: Let service install them
-   sudo systemctl restart ledmatrix
-   ```
-
-## Warning Messages
-
-### If you see this warning:
-```
-Installing plugin dependencies for current user (not root).
-These will NOT be accessible to the systemd service.
-For production use, install plugins via the web interface or restart the ledmatrix service.
-```
-
-**What it means:**
-- You're running as a non-root user
-- Dependencies were installed to your user directory only
-- The systemd service won't be able to use this plugin
-
-**What to do:**
 ```bash
-# Restart the service to install dependencies system-wide
+cd ~/LEDMatrix/plugin-repos/PLUGIN-NAME     # or your configured plugins directory
+sudo python3 -m pip install --break-system-packages --no-cache-dir -r requirements.txt
 sudo systemctl restart ledmatrix
 ```
 
+`--no-cache-dir` avoids errors about `/root/.cache/pip` not being writable.
+
 ## Troubleshooting
 
-### Plugin works when I run manually but fails in systemd service
-
-**Cause:** Dependencies installed to user directory (`~/.local/`) instead of system-wide
-
-**Fix:**
-```bash
-# Check where package is installed
-pip3 list -v | grep <package-name>
-
-# If it shows ~/.local/, reinstall system-wide:
-sudo pip3 install --break-system-packages <package-name>
-
-# Or just restart the service:
-sudo systemctl restart ledmatrix
-```
-
 ### Permission denied when installing dependencies
 
-**If you see errors like:**
 ```
 ERROR: Could not install packages due to an OSError: [Errno 13] Permission denied: '/root/.local'
 WARNING: The directory '/root/.cache/pip' or its parent directory is not owned or is not writable
 ```
 
-**Quick Fix - Use the Helper Script:**
-```bash
-sudo /home/ledpi/LEDMatrix/scripts/install_plugin_dependencies.sh
-sudo systemctl restart ledmatrix
-```
+Use one of the manual installs above (they pass `--no-cache-dir`).
 
-**Manual Fix:**
-```bash
-# Install dependencies with --no-cache-dir to avoid cache permission issues
-cd /home/ledpi/LEDMatrix/plugins/PLUGIN-NAME
-sudo pip3 install --break-system-packages --no-cache-dir -r requirements.txt
-sudo systemctl restart ledmatrix
-```

-## Recommendations
-
-1. **For end users:** Always use the web interface for plugin management
-2. **For developers:** Be aware of the user context when testing
-3. **For plugin authors:** Test with `sudo systemctl restart ledmatrix` to ensure dependencies install correctly
-4. **For CI/CD:** Always run installation as root or use the service
-
-## Helper Scripts
-
-### Install Plugin Dependencies Script
-
-Located at: `scripts/install_plugin_dependencies.sh`
-
-This script automatically finds and installs dependencies for all plugins:
+### Checking where a package is installed
 
 ```bash
-# Run as root (recommended for production)
-sudo /home/ledpi/LEDMatrix/scripts/install_plugin_dependencies.sh
+# How the service sees it
+sudo python3 -c "import package_name; print(package_name.__file__)"
 
-# Make executable if needed
-chmod +x /home/ledpi/LEDMatrix/scripts/install_plugin_dependencies.sh
+# A path under /home/<user>/.local/ means it was installed for that user only
+python3 -m pip show -f package_name
 ```
 
-Features:
-- Auto-detects all plugins with requirements.txt
-- Uses correct installation method (system-wide vs user)
-- Bypasses pip cache to avoid permission issues
-- Provides detailed logging and error messages
+For more, see the [Plugin Dependency Troubleshooting Guide](PLUGIN_DEPENDENCY_TROUBLESHOOTING.md).
+
+## For Plugin Authors
+
+1. Keep `requirements.txt` minimal and pin only what you need.
+2. Test that it installs the way the Pi will install it:
+   ```bash
+   sudo python3 -m pip install --break-system-packages --no-cache-dir -r requirements.txt
+   ```
+3. Note any `apt` packages your plugin needs in its README.

+
 ## Root Cause
 
-Plugin dependencies must be installed in a context accessible to the LEDMatrix systemd service, which runs as root. Permission errors typically occur when:
+Plugin packages must be importable by `ledmatrix.service`, which runs as
+root. The web interface (`ledmatrix-web.service`) runs as the user who
+installed LEDMatrix, so it installs through a sudo helper
+(`scripts/fix_perms/safe_pip_install.sh`). Problems usually come from:
 
-1. The pip cache directory has incorrect permissions
-2. The process tries to install to user directories without proper permissions
-3. Environment variables (like HOME) are not set correctly for the service context
+1. The sudoers rule for that helper missing, so the web UI installed the
+   packages for its own user only
+2. Running `python3 run.py` by hand as a normal user, which installs missing
+   packages into `~/.local/`
+3. pip's cache directory not being writable for root
 
 ## Solutions
 
-### Solution 1: Use the Manual Installation Script (Recommended)
-
-We provide a helper script that handles dependency installation correctly:
+### Solution 1: Restore the sudo rule, then reinstall
 
 ```bash
-# Run as root to install system-wide (for production)

-### Solution 3: Fix Cache Directory Permissions
+### Solution 4: Let the display service install them
 
-If you specifically have cache permission issues:
+When a plugin loads, the display service installs any missing requirements
+itself, as root:
+
+```bash
+sudo systemctl restart ledmatrix
+sudo journalctl -u ledmatrix -f     # watch for "Installing dependencies for plugin ..."
+```
+
+### Solution 5: Fix pip cache permissions
 
 ```bash
 # Option A: Skip the cache (recommended)
-sudo pip3 install --no-cache-dir --break-system-packages -r requirements.txt
+sudo python3 -m pip install --no-cache-dir --break-system-packages -r requirements.txt

+# Option B: Fix cache permissions
 sudo mkdir -p /root/.cache/pip
 sudo chown -R root:root /root/.cache
 sudo chmod -R 755 /root/.cache
 ```
 
-### Solution 4: Install via Web Interface
-
-The web interface handles dependency installation correctly in the service context:
-
-1. Access the web interface (`http://ledpi:5000` or `http://your-pi-ip:5000`)
-2. Open the **Plugin Manager** tab (use the **Plugin Store** section to
-   find the plugin, or **Install from GitHub**)
-3. Install the plugin through the web UI

-### How Dependency Installation Works
+### Where installs happen
 
-The `PluginManager._install_plugin_dependencies()` method:
-
-1. Detects if running as root using `os.geteuid() == 0`
-2. If root: Uses system-wide installation with `--break-system-packages --no-cache-dir`
-3. If not root: Uses user installation with `--user --break-system-packages --no-cache-dir`
-4. The `--no-cache-dir` flag prevents cache-related permission issues

+  → `install_requirements_file()` in `src/common/permission_utils.py`, which

 ## Quick Start
 
-### 1. Link a Plugin from GitHub
+Official plugins all live in one repository,
+[ledmatrix-plugins](https://github.com/ChuckBuilds/ledmatrix-plugins), with
+one directory per plugin under `plugins/` (there are no per-plugin
+`ledmatrix-<name>` repositories). The helper script links a plugin directory
+from a checkout of that monorepo into LEDMatrix's `plugins/` directory.

+### 1. Link an Official Plugin
 
 ```bash
-./scripts/dev/dev_plugin_setup.sh link-github music
+./scripts/dev/dev_plugin_setup.sh link-github football-scoreboard
 ```
 
 This will:
-- Clone `https://github.com/ChuckBuilds/ledmatrix-music.git` to `~/.ledmatrix-dev-plugins/ledmatrix-music`
-- Create a symbolic link from `plugins/music` to the cloned repository
-- Validate that the plugin has a proper `manifest.json`

+- Create a symbolic link named after the plugin's manifest id, e.g.
+  `plugins/football-scoreboard` → `~/.ledmatrix-dev-plugins/ledmatrix-plugins/plugins/football-scoreboard`
 
-### 2. Link a Local Plugin Repository
+`link-github music` finds the monorepo's `plugins/ledmatrix-music` directory
+and links it into LEDMatrix as `plugins/ledmatrix-music`, because
+`ledmatrix-music` is that plugin's manifest id.
 
-If you already have a plugin repository cloned locally:
+To work from your fork of the monorepo, set `github_user` in
+`dev_plugins.json` (see [Configuration](#configuration)).

+### 2. Link a Local Plugin Directory

+locally:
 
 ```bash
-./scripts/dev/dev_plugin_setup.sh link music ../ledmatrix-music
+./scripts/dev/dev_plugin_setup.sh link hello-world ../ledmatrix-plugins/plugins/hello-world

 ### Versioning Best Practices
 
 - **Use semantic versioning**: `MAJOR.MINOR.PATCH` (e.g., `1.2.3`)
-- **GitHub as source of truth**: the plugin store resolves versions in this
-  order: GitHub Releases → GitHub Tags → manifest from branch → git commit hash
-- **Automatic version bumping**: install the self-contained pre-push hook in
-  your plugin repo and patch versions bump themselves on push (a git tag
-  `v{version}` is created and `manifest.json` staged automatically):
-
-  ```bash
-  # From your plugin repository directory
-  cp /path/to/LEDMatrix/scripts/git-hooks/pre-push-plugin-version .git/hooks/pre-push
-  chmod +x .git/hooks/pre-push
-  ```
-
-  Set `SKIP_TAG=1` in the environment to skip auto-tagging for one push.
-- **Manual versioning**: only needed for major/minor bumps, CI pipelines that
-  bypass hooks, or forks without the hook — use
-  `scripts/bump_plugin_version.py`.
-- **Registry stores no versions**: `plugins.json` holds only metadata (name,
-  description, repo URL).
+- **Bump `version` in `manifest.json` by hand** for every change you ship.
+  There is no automatic version-bump hook or bump script.
+- **Official (monorepo) plugins**: after bumping the manifest, run
+  `python update_registry.py` in the `ledmatrix-plugins` checkout. It copies
+  each manifest's version into `plugins.json` as `latest_version`, which is
+  what the store compares installed versions against. Without it, users
+  won't be offered the update.
+- **Plugins in their own repository**: still bump the manifest `version`,

 ### Error Patterns
 
 When the same error occurs repeatedly (5+ times in 60 minutes), it's detected as a pattern and logged as a warning. This helps identify systemic issues.

-# LEDMatrix Plugin System - Implementation Summary
-
-> **Status note:** this is a high-level summary written during the
-> initial plugin system rollout. Most of it is accurate, but a few
-> sections describe features that are aspirational or only partially
-> implemented (per-plugin virtual envs, resource limits, registry
-> manager). Drift from current reality is called out inline.
-
-This document provides a comprehensive overview of the plugin architecture implementation, consolidating details from multiple plugin-related implementation summaries.
-
-## Executive Summary
-
-The LEDMatrix plugin system transforms the project into a modular, extensible platform where users can create, share, and install custom displays through a GitHub-based store (similar to Home Assistant Community Store).
-

-> Earlier drafts of this doc referenced `registry_manager.py`. It was
-> never created — discovery happens in `plugin_loader.py`. The earlier
-> default plugin location of `plugins/` has been replaced with
-> `plugin-repos/` (see `config/config.template.json:130`).
-
-### Key Design Decisions
-
-✅ **Gradual Migration**: Plugin system added alongside existing managers
-✅ **GitHub-Based Store**: Simple discovery from GitHub repositories
-✅ **Plugin Isolation**: Each plugin in dedicated directory
-✅ **Configuration Integration**: Plugins use main config.json
-✅ **Backward Compatibility**: Existing functionality preserved
-
-## Implementation Phases
-
-### Phase 1: Core Infrastructure (Completed)
-
-#### Plugin Base Classes
-- **BasePlugin**: Abstract interface for all plugins
-- **Standard Methods**: `update()`, `display()`, `get_config()`
-- **Lifecycle Hooks**: `on_enable()`, `on_disable()`, `on_config_change()`
-
-#### Plugin Manager
-- **Discovery**: Automatic plugin detection in `./plugins/` directory
-- **Loading**: Dynamic import and instantiation
-- **Management**: Enable/disable, configuration updates
-- **Error Handling**: Graceful failure isolation
-
-#### Store Manager
-- **GitHub Integration**: Repository cloning and management
-- **Version Handling**: Tag-based version control
-- **Dependency Resolution**: Automatic dependency installation
-
-### Phase 2: Configuration System (Completed)
-
-#### Nested Schema Validation
-- **JSON Schema**: Comprehensive configuration validation
-- **Type Safety**: Ensures configuration integrity
-- **Dynamic UI**: Schema-driven configuration forms
-
-#### Tabbed Configuration Interface
-- **Organized UI**: Plugin settings in dedicated tabs
-- **Real-time Validation**: Instant feedback on configuration changes
-- **Backup System**: Automatic configuration versioning
-
-#### Live Priority Management
-- **Dynamic Switching**: Real-time display priority changes
-- **API Integration**: RESTful priority management
-- **Conflict Resolution**: Automatic priority conflict handling
-
-### Phase 3: Advanced Features (Completed)
-
-#### Custom Icons
-- **Plugin Branding**: Custom icons for plugin identification
-- **Format Support**: PNG, SVG, and font-based icons
-- **Fallback System**: Default icons when custom ones unavailable
-
-#### Dependency Management
-- **Requirements.txt**: Per-plugin dependencies, installed system-wide
-  via pip on first plugin load
-- **Version Pinning**: Standard pip version constraints in
-  `requirements.txt`
-
-> Earlier plans called for per-plugin virtual environments. That isn't
-> implemented — plugin Python deps install into the system Python
-> environment (or whatever environment the LEDMatrix service is using).
-> Conflicting versions across plugins are not auto-resolved.
-
-#### Health monitoring
-- **Resource Monitor** (`src/plugin_system/resource_monitor.py`): tracks
-  CPU and memory metrics per plugin and warns about slow plugins
-- **Health Monitor** (`src/plugin_system/health_monitor.py`): tracks
-  plugin failures and last-success timestamps
-
-> Earlier plans called for hard CPU/memory limits and a sandboxed
-> permission system. Neither is implemented. Plugins run in the same
-> process as the display loop with full file-system and network access
-> — review third-party plugin code before installing.

+This page explains how the official plugin registry works and how a plugin
+gets into it. The registry and the official plugins both live in one
+repository, [ledmatrix-plugins](https://github.com/ChuckBuilds/ledmatrix-plugins);
+its `SUBMISSION.md`, `VERIFICATION.md` and `docs/` are the authoritative

-## Step 1: Create plugins.json
+- **Registry.** The Plugin Store fetches
+  `https://raw.githubusercontent.com/ChuckBuilds/ledmatrix-plugins/main/plugins.json`
+  (`PluginStoreManager.REGISTRY_URL` in `src/plugin_system/store_manager.py`)
+  and caches it for 15 minutes.
+- **Monorepo plugins** have `repo` set to the ledmatrix-plugins URL and
+  `plugin_path` set to their directory (`plugins/<id>`). The store downloads
+  just that directory (GitHub API, falling back to the repository ZIP), so
+  installed copies have no `.git` directory.
+- **Third-party plugins** keep their own repository: `repo` points at it and
+  `plugin_path` is empty. The store installs them with `git clone`, falling
+  back to an archive download.
+- **Updates.** For registry plugins the store compares the installed
+  manifest's `version` with the entry's `latest_version`. Git tags and GitHub
+  releases are not read.
 
-This is the **core file** that the Plugin Store reads from.
-
-**Important**: The registry stores **metadata only** (name, description, repo URL, etc.). 
-The plugin store always pulls the latest commit information directly from GitHub, so you never manage semantic versions here.
-
-**File**: `plugins.json`

-**Note**: There's no need for version arrays or release tracking. The store queries GitHub for the latest commit details (date, branch, and short SHA) whenever metadata is requested.
+[plugin_registry_template.json](plugin_registry_template.json) shows a
+monorepo entry and a third-party entry.
 
-## Step 2: Create Plugin Repositories
+Don't edit `latest_version` or `last_updated` by hand for monorepo plugins:
+`update_registry.py` in ledmatrix-plugins writes them from each plugin's
+`manifest.json`.
 
-Each plugin should have its own repository:
+## Adding or changing an official plugin
 
-### Example: Creating clock-simple Plugin
+1. Add or edit `plugins/<your-plugin-id>/` in the monorepo, with the
+   manifest fields listed in
+   [PLUGIN_API_REFERENCE.md](PLUGIN_API_REFERENCE.md#manifest-required-fields).
+2. Bump `version` in the plugin's `manifest.json` for every change, or users
+   won't be offered the update.
+3. Run `python update_registry.py` in ledmatrix-plugins and commit the
+   updated `plugins.json` with the plugin change.
+4. Open a pull request. The monorepo's CI and review steps are described in
+   its `SUBMISSION.md`.

-
-Guidelines for community plugin submissions:
-
-```markdown
-# Plugin Submission Guidelines
-
-Want to add your plugin to the official registry? Follow these steps!
-
-## Requirements
-
-Before submitting, ensure your plugin:
-
-- ✅ Has a complete `manifest.json` with all required fields
-- ✅ Follows the plugin architecture specification
-- ✅ Has comprehensive README documentation
-- ✅ Includes example configuration
-- ✅ Has been tested on Raspberry Pi hardware
-- ✅ Follows coding standards (PEP 8)
-- ✅ Has proper error handling
-- ✅ Uses logging appropriately
-- ✅ Has no hardcoded API keys or secrets
-
-## Submission Process
-
-1. **Test Your Plugin**
-   ```bash
-   # Install via URL on your Pi
-   curl -X POST http://your-pi:5000/api/v3/plugins/install-from-url \
-     -d '{"repo_url": "https://github.com/you/ledmatrix-your-plugin"}'
-   ```
-
-2. **Fork This Repo**
-   Fork [ledmatrix-plugins](https://github.com/ChuckBuilds/ledmatrix-plugins)
-
-4. **Update plugins.json**
-   Add your plugin entry (metadata only - no versions needed):
-   ```json
-   {
-     "id": "your-plugin",
-     "name": "Your Plugin Name",
-     "description": "What it does",
-     "author": "YourName",
-     "category": "custom",
-     "tags": ["tag1", "tag2"],
-     "repo": "https://github.com/you/ledmatrix-your-plugin",
-     "branch": "main",
-     "verified": false
-   }
-   ```
-
-5. **Submit Pull Request**
-   Create PR with title: "Add plugin: your-plugin-name"
-
-## Review Process
-
-1. **Automated Checks**: Manifest validation, structure check
-2. **Code Review**: Manual review of plugin code
-3. **Testing**: Test installation and basic functionality
-4. **Approval**: If accepted, merged and marked as verified
-
-## After Approval
-
-- Plugin appears in official store
-- `verified: true` badge shown
-- Included in plugin count
-- Featured in README
-
-## Updating Your Plugin
-
-Whenever you push new commits to your plugin repository's default branch, the store will automatically surface the latest commit timestamp and short SHA. No release tagging or manifest version bumps are required.
-
-You only need to update the registry if:
-- Plugin metadata changes (name, description, category, etc.)
-- Repository URL changes
-- You want to update the verified status
-
-To update metadata:
-1. Fork the registry repo
-2. Update plugins.json with new metadata
-3. Submit PR with changes
-4. We'll review and merge
-
-## Questions?
-
-Open an issue in this repo or the main LEDMatrix repo.
-```
-
-## Step 5: Create VERIFICATION.md
-
-Checklist for verifying plugins:

-
-## Step 6: Workflow for Adding Plugins
-
-### For Your Own Plugins
+## Testing locally
 
 ```bash
-# 1. Create plugin in separate repo
-mkdir ledmatrix-clock-simple
-cd ledmatrix-clock-simple
-# ... create plugin files ...
+# Validate a plugin headlessly (from LEDMatrix)
+python3 scripts/check_plugin.py --plugin <id>
 
-# 2. Push to GitHub
-git init
-git add .
-git commit -m "Initial commit"
-git remote add origin https://github.com/ChuckBuilds/ledmatrix-clock-simple
-git push -u origin main
-
-# 3. Update registry
-cd ../ledmatrix-plugins
-# Edit plugins.json to add new entry
-git add plugins.json
-git commit -m "Add clock-simple plugin"
-git push
-```
-
-### For Community Submissions
-
-```bash
-# 1. Receive PR on ledmatrix-plugins repo
-# 2. Review using VERIFICATION.md checklist
-# 3. Test installation:
-curl -X POST http://pi:5000/api/v3/plugins/install-from-url \
-  -d '{"repo_url": "https://github.com/contributor/plugin"}'
-
-# 4. If approved, merge PR
-# 5. Set verified: true in plugins.json
-```
-
-## Step 7: Maintaining the Registry
-
-### Regular Updates
-
-```bash
-# Refresh local clones of all plugin repos
-python3 scripts/update_plugin_repos.py
-
-# (Re-)create local plugin repo checkouts from the registry
-python3 scripts/setup_plugin_repos.py
-
-# Audit installed plugins for manifest/schema problems
-python3 scripts/audit_plugins.py
-
-# Validate a single plugin
-python3 scripts/check_plugin.py --plugin <plugin-id>
-```
-
-Registry regeneration (`update_registry.py`) lives in the
-`ledmatrix-plugins` monorepo, not in this repo.
-
-## Converting Existing Plugins
-
-To convert your existing plugins (hello-world, clock-simple) to this system:
-
-### 1. Move to Separate Repos
-
-```bash
-# For each plugin in plugins/
-cd plugins/clock-simple
-
-# Create new repo
-git init
-git add .
-git commit -m "Extract clock-simple plugin"
-git remote add origin https://github.com/ChuckBuilds/ledmatrix-clock-simple
-git push -u origin main
-git tag v1.0.0
-git push origin v1.0.0
-```
-
-### 2. Add to Registry
-
-Update `plugins.json` in ledmatrix-plugins repo.
-
-### 3. Keep or Remove from Main Repo
-
-Decision:
-- **Keep**: Leave in main repo for backward compatibility
-- **Remove**: Delete from main repo, users install via store
-
-## Testing the Registry
-
-After setting up:
-
-```bash
-# Test registry fetch
-curl https://raw.githubusercontent.com/ChuckBuilds/ledmatrix-plugins/main/plugins.json
-
-# Test plugin installation
+# Fetch the registry the way the store does
 python3 -c "
 from src.plugin_system.store_manager import PluginStoreManager
-store = PluginStoreManager()
-registry = store.fetch_registry()
-print(f'Found {len(registry[\"plugins\"])} plugins')
+store = PluginStoreManager(plugins_dir='plugin-repos')
+print(len(store.fetch_registry(force_refresh=True).get('plugins', [])), 'plugins')
 "
 ```
 
-## Benefits of This Setup
-
-✅ **Centralized Discovery**: One place to find all official plugins  
-✅ **Decentralized Storage**: Each plugin in its own repo  
-✅ **Easy Maintenance**: Update registry without touching plugin code  
-✅ **Community Friendly**: Anyone can submit via PR  
-✅ **Version Control**: Track plugin versions and updates  
-✅ **Verified Badge**: Show trust with verified plugins  
-
-## Next Steps
-
-1. Create `plugins.json` in your repo
-2. Update the registry URL in LEDMatrix code (already done)
-3. Create SUBMISSION.md and README.md
-4. Move existing plugins to separate repos
-5. Add them to the registry
-6. Announce the plugin store!
+To work on monorepo plugins against a LEDMatrix checkout, see
+[MULTI_ROOT_WORKSPACE_SETUP.md](MULTI_ROOT_WORKSPACE_SETUP.md) and the
+[Plugin Development Guide](PLUGIN_DEVELOPMENT_GUIDE.md).

 The LEDMatrix Plugin Store allows you to discover, install, and manage display plugins for your LED matrix. Install curated plugins from the official registry or add custom plugins directly from any GitHub repository.
 
+In the web interface, the **Plugin Store** is a section of the **Plugin
+Manager** tab (below the installed plugins), followed by an **Install from
+GitHub** section.
+
+The Python examples below pass `plugins_dir="plugin-repos"`:
+`PluginStoreManager()` defaults to `plugins`, but the web interface and the

+(`plugin-repos` by default).

+## Soaking a rig
+
+The per-scroller lines above tell you *which* scroller misbehaves. The soak
+answers the question a release has to answer for each rig: **over a long run,
+how often did a moving frame reach the panel late?**
+
+Every frame reaches the panel through `DisplayManager.update_display`, so it is
+timed there once, whoever drew it -- Vegas, a ticker plugin, anything. The
+render thread only appends a tuple; a worker thread aggregates and rewrites
+`/dev/shm/ledmatrix_frame_stats.json` every 10 seconds (RAM, so no SD-card
+wear). `src/common/frame_timing.py` has the details.
+
+```bash
+python3 scripts/frame_soak.py                 # 10 minutes, as the display is now
+python3 scripts/frame_soak.py --preview       # with the web preview open
+python3 scripts/frame_soak.py --show          # totals since the service started
+python3 scripts/frame_soak.py --json a.json   # keep the report to compare later
+```
+
+It runs as any user next to the display service and stops nothing. It needs
+something to *scroll* during the run: a live game holding a static scoreboard
+on screen gives no verdict. `--preview` keeps the web preview's viewer marker
+fresh, which puts the preview's PNG encoding at full rate -- run it as the web
+service's user.
+
+| line | what it tells you |
+|---|---|
+| **Late frames** | Frames presented one or more refreshes after they were due: the panel showed the previous frame again, a visible hitch. **The pass/fail number**, 0.1% by default (`--max-late-pct`). Only intervals between two scrolling frames count, and a frame held for `frame_hold` refreshes is due `frame_hold` refreshes after the last. |
+| **Freezes** | Gaps of 250 ms or more inside a scroll: recomposes, plugin handovers, blocking calls on the render thread. Reported but not failed on, because some are handovers between plugins rather than faults. A gap still counts when the display's scroll state went missing for one frame across it, as long as scrolling resumes within 1 s: both of that frame's intervals count. Two static frames in a row end the scroll. (The state expires after 2 s without scroll activity, and plugins can clear it from their own `display()`.) The late and early rates are over frames judged against a known refresh period, which the recorder adopts once two windows in a row agree on it. |
+| **blit** | Copying the frame into the matrix canvas (`SetImage`). It grows with width × height × `pwm_bits`: ~5.5 ms at 512×64 with 8 bits on a Pi 4. It is the biggest fixed cost, and it sets the refresh rates a rig can hold one pixel per refresh at. |
+| **wait** | Time blocked in `SwapOnVSync`, i.e. the slack left in each refresh. A p50 near zero means the rig has no headroom and anything extra lands a frame late. |
+| **work** | Everything else between two frames: drawing, scrolling, and waiting for the GIL. A wide gap between its p50 and p99 is another thread getting in the way. |
+| **Binding** | `STOCK` means the rgbmatrix binding holds the GIL through the vsync wait, which starves every other thread. See *Rebuilding the binding*. |
+
+The refresh rate is estimated from the frames themselves (swaps that block on
+vsync can only land on refresh boundaries). Cross-check it with
+`scroll_speeds.py --measure` if it looks wrong. It can read high on a rig where
+nothing ever presented at the full refresh rate.
+
+A soak is only meaningful against a fixed workload. Compare runs with the same
+content and `--preview` setting, and alternate which build goes first when you
+A/B two of them. A live-API workload drifts over time.
+
+The soak says how often; the service's log says why. A scroll that presents no
+frame for 250 ms logs `Render stall:` with the stack of the render thread and
+the top of every other thread's, and whether the whole interpreter was blocked
+(C code holding the GIL) rather than one thread. To see what is behind the
+shorter hitches, run the service with `LEDMATRIX_STALL_WATCHDOG_MS=30`, which
+dumps at three refreshes late instead: its extra polling costs a little GIL
+time of its own, so do that on a diagnostic run, not a soak you are grading.
+`LEDMATRIX_STALL_WATCHDOG=0` turns it off.

+- Blending cost the panel refresh rate as well as frames: 94.5 Hz against
+  ~100 Hz for the same hardware under whole-pixel pacing.
+- The freezes and the 3+ rows in the #628 runs line up with canvas-bound
+  plugins fetched on the render thread (`drain_deferred`): `news` took ~320 ms
+  and `hockey-scoreboard` ~660 ms there. Moving those
+  fetches off the render thread is proposed separately (offscreen rendering).
+- Run 5 changed two things at once: the speed, and `pwm_bits` (changed on the
+  rig between runs). Its lower late rate cannot be credited to either alone.
+- These soaks were taken before the recorder counted 1–2 s stalls as freezes,
+  so a stall of that length would be missing from these rows.
+
+### Without the service: `render_bench.py`
+
+The soak measures the service as it really runs: live content, plugin
+updates, the web preview. `scripts/render_bench.py` answers the narrower
+question underneath: *with nothing else in the way, can this hardware present
+every frame on time?* It scrolls a synthetic strip through the production path
+-- a real `DisplayManager`, a real `ScrollHelper`, the same `scroll_config`
+resolver every ticker uses -- on content that is identical every run, which
+makes it the tool for comparing rigs (a Pi 3 against a Pi 4, one HAT against
+another) and for A/B testing a change to the render path.
+
+```bash
+sudo systemctl stop ledmatrix          # the service owns the GPIO
+
+sudo python3 scripts/render_bench.py                 # 60s at one pixel per refresh
+sudo python3 scripts/render_bench.py --seconds 600   # the shipping gate
+sudo python3 scripts/render_bench.py --speed 50      # a held (frame_hold 2) speed
+sudo python3 scripts/render_bench.py --busy 2        # with threads imitating plugin updates
+sudo python3 scripts/render_bench.py --json /tmp/pi4-512x64.json
+
+sudo systemctl start ledmatrix
+```
+
+It never starts or stops the service itself, so a crash in it cannot leave
+the panel dark. It grades with the same recorder as the soak and prints the
+same report, with the same exit status, except that **2** also means the run
+could not be set up at all (no root, no panel, a fallback display), so a rig
+that was never measured cannot pass by accident.
+
+Two differences from the soak matter:
+
+- **It measures the panel first.** Before scrolling it times bare swaps for a
+  few seconds to get the idle refresh rate, and seeds the recorder with it.
+  That is what catches a loop that never locked to the panel at all. The first
+  version of the bench announced its scrolling state once instead of every
+  frame; the state expired, the dirty-tracking skip fired mid-scroll, and the
+  loop free-ran at 827 fps. Graded against its own frames that looks perfectly
+  steady; graded against the panel's measured rate every frame is early, and
+  the run fails as NOT LOCKED. (The soak has no idle measurement, so it checks
+  the rate against `limit_refresh_rate_hz` instead: a "refresh" faster than
+  the cap cannot have been waiting for the panel.)
+- **The stall watchdog prints to the terminal.** A frame held up for more than
+  250 ms prints the stack of what held it up, in the middle of the run.
+
+Measured with the first version of the bench on hdpi (Pi 4, 512x64,
+`pwm_bits` 8), two-minute runs at one pixel per refresh: 8 of 11,449 frames
+late (0.070%), and with `--busy 2` 3 of 11,445 (0.026%). The render path and
+the hardware pass on their own. Compare the soak results above, from the same
+rig with the service running, for how much of the late rate comes from
+everything else.
+
+### The panel is slower while you are rendering into it
+
+The bench prints two refresh rates, and they differ:
+
+| | Pi 4, 512x64, `pwm_bits` 8 |
+|---|---|
+| idle, timing bare swaps | 100.4 Hz |
+| while scrolling | 96.3 Hz |
+
+Both are real. Driving an LED matrix is bit-banging on the same machine, so
+`SetImage` over a 512x64 chain contends with the refresh itself and slows it.
+The recorder therefore reads the rendering rate back from the frames: swaps
+that block on vsync can only return on a refresh boundary, so the low end of
+`interval / frame_hold` is the period. The idle figure is still printed,
+because the gap between the two is itself a measure of how expensive a frame
+is: **a rise in that gap is a render-cost regression even when nothing is
+late.**
+
+The practical consequence for config: set `limit_refresh_rate_hz` near the rate
+the panel holds *while rendering*, not the idle rate and certainly not a cap it
+can never reach. A cap well above the real rate makes `scroll_config` solve
+speeds against a refresh that does not exist, which is where "3px every 4
+refreshes" comes from.
+
+### Bench-only counters
+
+| line | meaning |
+|---|---|
+| `duplicate` | frames that advanced no pixels. A crisp fixed-step scroll should show none; any at all means the loop is presenting faster than the strip is moving. |
+| `blank` | frames with no visible slice to draw: the helper had no content. Should be zero. |
+| `restarts` | how many times the strip was scrolled through end to end. Informational: the bench restarts the strip where a plugin would hand over to the next one. |
+
+`--json` writes the full report plus the panel geometry, the solved speed and
+these counters, so two rigs (or one rig before and after a change) can be
+compared without re-reading a terminal.
+
+---
+
+## A tear across the middle on fast scrolls
+
+**Symptom:** while text scrolls, the top and bottom halves of the panel look
+shifted sideways against each other along a horizontal line at mid-height, and
+the shift grows with scroll speed. It shows most in Vegas mode at high speed.
+
+**It is the panel's scan, not the software.** The measured panel, like most
+64-row panels, is multiplexed 1:32 (some panels of the same size scan
+differently, so check yours): it lights two rows at a time, one from each half
+(row 0 with row 32, row 1 with row 33, …), stepping down both halves together
+once per refresh. So row 31,
+the last row of the top half, lights almost a whole refresh period after row 32
+right below it. Your eye follows moving text, and moving content that lights at
+different times lands in different places, so the two rows meet with an offset
+of roughly
+
+```
+offset ≈ scroll speed × refresh period
+```
+
+Each frame reaches the panel whole (`SwapOnVSync` swaps complete frames between
+refreshes); the shift is created inside a single refresh. Other panel heights
+show it too, at the point where their two scan halves meet.
+
+On the 2×128×64 chain above, which refreshes at about 130 Hz flat out
+(7.7 ms per pass):
+
+| scroll speed | offset at the midline |
+|---|---|
+| 50 px/s (Vegas default) | ~0.4 px |
+| 100 px/s | ~0.8 px |
+| 150 px/s | ~1.2 px, plainly visible |
+
+### What the display does about it
+
+At one pixel per refresh, the fastest crisp speed, the step is exactly one
+refresh's worth of motion, so it can be cancelled: show one half of the panel
+a refresh behind the other -- the half whose row at the seam lights at the
+start of each refresh. The two rows either side of the seam then show the same
+moment again. What is left is a
+lean of one pixel per half from top to bottom, continuous across the panel,
+which reads as nothing where the step read as a tear. `DisplayManager` does
+this while something scrolls at one frame per refresh
+(`display.scan_order_compensation`, `"auto"` by default, `"off"` to disable;
+the geometry is in `src/scan_order.py`). The lagging rows come from the
+previous frame the display presented, so it works for Vegas and every plugin
+ticker without knowing how they scroll.
+
+Checked on hdpi (4×128×64 on one chain, rotated 180, 2026-09-24) before it was
+written: `scan_mode: 1` (interlaced) made the step vanish but turned moving
+edges grainy, and halving the speed halved it, so it is the scan and not a torn
+frame. With the compensation the step is gone at 90 px/s.
+
+It is left off where the row order is unknown or the maths does not hold:
+
+- **Slower speeds**, where each frame is held for two or more refreshes. The
+  offset there is half a pixel or less, and cancelling it would need a lag of
+  a fraction of a frame.
+- **Other layouts:** pixel mappers other than a 0 or 180 degree rotation
+  (U-mapper, 90/270), non-zero `multiplexing`, interlaced `scan_mode`, and a
+  canvas remapped to another height (double-sided mode).
+- **The emulator,** which has no scan order.
+
+### When it cannot apply
+
+Only a shorter scan period (a faster refresh) or a slower scroll. Measure what
+the panel actually achieves first. The library prints the rate with a carriage
+return and no newline, so read it from the raw journal:
+
+```bash
+# set display.hardware.show_refresh_rate to true (web UI, Display tab), restart, then:
+journalctl -u ledmatrix --since "-1min" --no-pager -o cat --all | grep -a -oE "[0-9.]+Hz" | tail -5
+```
+
+Turn it off again afterwards. Measured on that panel (Pi 4, single chain),
+changing one setting at a time from `pwm_bits: 7`, `gpio_slowdown: 3`:
+
+| change | refresh, uncapped | notes |
+|---|---|---|
+| none | ~130 Hz | the ceiling for this wiring |
+| `pwm_bits: 6` | ~138 Hz | barely faster, and half the colour depth |
+| `gpio_slowdown: 2` | ~130 Hz | no faster, **and visible glitching**; keep 3 |
+| `limit_refresh_rate_hz: 0` | ~130 Hz | Vegas dropped from 100 to 72–95 fps as the refresh thread took more CPU |
+
+None of these helps much, because the time goes into shifting each row's pixels
+out: a 2×128 chain pushes 256 pixels per row down one output. What does help is
+**fewer pixels per output**. On a bonnet with more than one output (the
+`regular` and `classic` mappings have 3; `adafruit-hat` has 1), put each panel
+on its own output and set `parallel` to the number of outputs used and
+`chain_length` to the panels per output, for example `parallel: 2`,
+`chain_length: 1` for two panels. Each refresh then shifts half the data, which
+should roughly double the refresh rate and halve the offset. That is a cable
+change, so measure again afterwards.
+
+Short of rewiring, keep fast scrolls moderate on those layouts: at 50 px/s the
+offset is under half a pixel.

-A skin replaces only the *look* of a scoreboard — the host plugin keeps doing
-data fetching, scheduling, caching, dedup, live-priority takeover, and vegas
-mode. If you only want to **build** a skin, read
-[CREATING_SKINS.md](CREATING_SKINS.md); this document explains how the system
-works and why it is shaped this way.
-
-## Why skins instead of forks
-
-Before skins, changing a scoreboard's layout meant forking the whole plugin
-(e.g. the community MLB scoreboard fork). The fork gets the new look but loses
-everything the maintained plugin keeps earning: duration/scheduling behavior,
-vegas mode support, caching and background-fetch improvements, bug fixes. It
-also silently drifts: every upstream improvement now has to be re-ported by
-hand.
-
-A skin inverts that trade. The plugin remains stock and keeps updating through
-the store; the skin is ~100 lines of pure rendering code that receives the
-plugin's already-fetched data each frame. Uninstalling the skin (or the skin
-crashing) simply restores the built-in look.

-              live priority                        draws onto ctx.canvas
-```
-
-## The render funnel
-
-A sports scoreboard built on the `src/base_classes/sports/` package
-(`core.py`) renders through exactly one seam. No current scoreboard plugin is
-built on it (see [Status](#status-not-supported-yet)), so for them this seam is
-never reached:
-`SportsCore._render_game(game, force_clear)`.
-
-1. The mode class's `display()` (live, `SportsUpcoming`, `SportsRecent`)
-   picks `self.current_game` and calls `_render_game`.
-2. `_render_game` lazily loads the configured skin (once, on first render —
-   a broken skin can never block plugin startup).
-3. If a skin is active, the host builds a `SkinContext` — a fresh black
-   canvas at the current display size plus layout/font/logo helpers — and
-   calls the skin's `render_live` / `render_recent` / `render_upcoming`
-   with a **copy** of the game dict.
-4. If the skin returns `True`, the canvas is composited onto the display.
-   If it returns `False`, isn't implemented for that mode, or raises, the
-   built-in `_draw_scorebug_layout` runs instead.
-
-Key properties that fall out of this design:
-
-- **Per-mode fallback.** A skin that only implements `render_live` gets the
-  stock recent/upcoming screens for free.
-- **Three strikes.** A skin that raises 3 times in a row is disabled for the
-  rest of the session (one loud error log per failure); the display never
-  goes dark. Restarting the service re-arms it.
-- **Copies, not references.** Skins receive a shallow copy of the game dict,
-  so a buggy skin cannot corrupt the plugin's scheduling state.
-- **Vegas mode works untouched.** Vegas capture falls back to grabbing the
-  regular `display()` output, which is already skin-rendered. Skins can
-  additionally implement `render_vegas_card` for purpose-built scroll cards,
-  and hosts can call `SportsCore.render_skin_card(game, size)` to use it.
-- **Hot-loop caution.** `render_live` runs every display-loop pass during a
-  live game. The host logs a warning when a skin render exceeds 150 ms, and
-  `scripts/validate_skin.py` enforces a budget at development time — but
-  Python cannot forcibly time-out a stuck render, so a skin that blocks
-  (network I/O, giant image ops) stalls the display. This is why the rules
-  in CREATING_SKINS.md ban I/O in render paths.
-
-## The view model contract
-
-The `game` dict a skin receives is the plugin's already-extracted view model
-(`SportsCore._extract_game_details_common` plus per-sport extras from
-`src/base_classes/{baseball,basketball,football,hockey}.py`).
-
-- **Guaranteed keys (view model v1.0)** — always present for every sport:
-  `id`, `game_time`, `game_date`, `start_time_utc` (a UTC `datetime`),
-  `status_text`, `is_live`, `is_final`, `is_upcoming`, `is_halftime`,
-  `home_abbr`/`away_abbr`, `home_id`/`away_id`, `home_score`/`away_score`
-  (**strings**), `home_logo_path`/`away_logo_path`, `home_record`/`away_record`.
-- **Sport extras** — documented per sport in CREATING_SKINS.md (e.g. baseball
-  adds `inning`, `inning_half`, `balls`, `strikes`, `outs`, `bases_occupied`).
-- **Optional keys** (`odds`, rankings, `series_summary`, …) are present only
-  when the feature is enabled — skins must always use `.get()`.
-
-Versioning policy: additive changes bump the minor version
-(`VIEW_MODEL_VERSION` in `src/skin_system/skin_base.py`, surfaced to skins as
-`ctx.view_model_version`); renaming or removing a guaranteed key requires a
-major bump plus a compat shim. `test/test_skin_system.py::TestViewModelContract`
-fails CI if a guaranteed key disappears from the extractor.
-
-Separately, `SKIN_API_VERSION` versions the Python API (`ScoreboardSkin`,
-`SkinContext`). The loader refuses a skin whose manifest declares a different
-major version and falls back to the built-in renderer with a clear
-"skin needs an update" log line.
-
-## Package layout and lifecycle
-
-```text
-skins/<skin-id>/
-  skin.json      # manifest (required)
-  skin.py        # ScoreboardSkin subclass (required)
-  preview.png    # optional, shown by the web UI
-  assets/        # optional skin-local images
-  helpers.py ... # optional extra modules (namespaced per skin at import)
-```
-
-Skins live in the central `skins/` directory — deliberately **not** inside the
-plugin's directory, because plugin reinstall/update deletes the whole plugin
-directory and a skin must survive that. One skin can also target several
-plugins (mlb + milb).
-
-Lifecycle: discovered lazily on first render → manifest validated → API major
-version gated → module imported under a namespaced `sys.modules` key (two
-skins can both ship a `helpers.py`, same scheme plugins use) → instantiated
-with `(manifest, options)`. Every failure logs and falls back to built-in.
-
-Skins should be **stateless**: the live, recent, and upcoming mode classes
-each hold their own skin instance, so derive everything from `(ctx, game)`.
-
-## Selection and configuration
-
-Inside the plugin's own config section in `config/config.json`:
-
-```json
-"baseball-scoreboard": {
-  "skin": "retro-baseball",
-  "skin_options": { "accent_color": [255, 80, 0] }
-}
-```
-
-`"skin"` is either one id for all modes or a per-mode mapping
-(`{"live": "retro-baseball", "recent": "built-in"}`). Absent, empty, or
-`"built-in"` means the stock renderer. Because this rides the plugin's config
-section, it persists across plugin reinstalls like every other setting.
-
-`SchemaManager.inject_skin_selector` can add a **Visual Skin** enum to the
-*served* schema for plugins with matching skins installed. While skins are
-unsupported the plugin schema endpoint does not call it, so the dropdown is
-not shown. Validation never sees the enum either way: the base schema allows
-any `skin` value, so a config that references an uninstalled skin stays valid.
-`GET /api/v3/skins` lists installed skins (optionally filtered by
-`?plugin_id=`) and reports `"supported": false`.
-
-## Distribution
-
-- **Manual:** `git clone <skin repo> skins/<skin-id>` — that's the whole
-  install. No manifest bumps, no `update_registry.py`; skins are not monorepo
-  plugins.
-- **Store (disabled while unsupported):** registry entries with
-  `"type": "skin"` are hidden from the store list and refused on install.
-  `PluginStoreManager._install_skin_from_info` is kept: once
-  `SKINS_RENDER_SUPPORTED` in `src/skin_system/__init__.py` is true, such
-  entries install through the same `plugins.json` pipeline, land in `skins/`,
-  are validated against `skin.json` (including the API major version) instead
-  of `manifest.json`, and never install dependencies — skins are render-only
-  (stdlib + PIL + the provided context, no third-party packages in v1).
-
-## Trust model
-
-A skin is Python executing inside the display service — **exactly the same
-trust level as a plugin**, even though "skin" sounds cosmetic. Only install
-skins from sources you'd be willing to install a plugin from.
-
-## v2 directions (not in v1)
-
-- A generic `BasePlugin` opt-in (`render_with_skin()`) so non-sports plugins
-  (weather, music) can offer skinnable layouts; `skin_runtime` is already
-  sports-agnostic in anticipation.
-- Store UI: preview gallery, one-click install from the skin browser.
-- An update path for git-cloned skins (today: re-clone or store reinstall).
-- Animation support in skins (today the API is one frame per render call;
-  stateful tricks work but are at-your-own-risk).

-# AP Mode Manual Enable Configuration
-
-## Overview
-
-By default, Access Point (AP) mode is **not automatically enabled** after installation. AP mode must be manually enabled through the web interface when needed.
-
-## Default Behavior
-
-- **Auto-enable AP mode**: `false` (disabled by default)
-- AP mode will **not** automatically activate when WiFi or Ethernet disconnects
-- AP mode can only be enabled manually through the web interface
-
-## Why Manual Enable?
-
-This prevents:
-- AP mode from activating unexpectedly after installation
-- Network conflicts when Ethernet is connected
-- SSH becoming unavailable due to automatic AP mode activation
-- Unnecessary AP mode activation on systems with stable network connections
-
-## Enabling AP Mode
-
-### Via Web Interface
-
-1. Navigate to the **WiFi** tab in the web interface
-2. Click the **"Enable AP Mode"** button
-3. AP mode will activate if:
-   - WiFi is not connected AND
-   - Ethernet is not connected
-
-### Via API
-
-```bash
-# Enable AP mode
-curl -X POST http://localhost:5001/api/v3/wifi/ap/enable
-
-# Disable AP mode
-curl -X POST http://localhost:5001/api/v3/wifi/ap/disable
-```
-
-## Enabling Auto-Enable (Optional)
-
-If you want AP mode to automatically enable when WiFi/Ethernet disconnect:
-
-### Via Web Interface
-
-1. Navigate to the **WiFi** tab
-2. Look for the **"Auto-enable AP Mode"** toggle or setting
-3. Enable the toggle
-
-### Via Configuration File
-
-Edit `config/wifi_config.json`:
-
-```json
-{
-  "auto_enable_ap_mode": true,
-  ...
-}
-```
-
-Then restart the WiFi monitor service:
-
-```bash
-sudo systemctl restart ledmatrix-wifi-monitor
-```
-
-### Via API
-
-```bash
-# Get current setting
-curl http://localhost:5001/api/v3/wifi/ap/auto-enable
-
-# Set auto-enable to true
-curl -X POST http://localhost:5001/api/v3/wifi/ap/auto-enable \
-  -H "Content-Type: application/json" \
-  -d '{"auto_enable_ap_mode": true}'
-```
-
-## Behavior Summary
-
-| Auto-Enable Setting | WiFi Status | Ethernet Status | AP Mode Behavior |
-|---------------------|-------------|-----------------|------------------|
-| `false` (default) | Any | Any | Manual enable only |
-| `true` | Connected | Any | Disabled |
-| `true` | Disconnected | Connected | Disabled |
-| `true` | Disconnected | Disconnected | **Auto-enabled** |
-
-## When Auto-Enable is Disabled (Default)
-
-- AP mode **never** activates automatically
-- Must be manually enabled via web UI or API
-- Once enabled, it will automatically disable when WiFi or Ethernet connects
-- Useful for systems with stable network connections (e.g., Ethernet)
-
-## When Auto-Enable is Enabled
-
-- AP mode automatically enables when both WiFi and Ethernet disconnect
-- AP mode automatically disables when WiFi or Ethernet connects
-- Useful for portable devices that may lose network connectivity
-
-## Troubleshooting
-
-### AP Mode Not Enabling
-
-1. **Check if WiFi or Ethernet is connected**:
-   ```bash
-   nmcli device status
-   ```
-
-2. **Check auto-enable setting**:
-   ```bash
-   python3 -c "
-   from src.wifi_manager import WiFiManager
-   wm = WiFiManager()
-   print('Auto-enable:', wm.config.get('auto_enable_ap_mode', False))
-   "
-   ```
-
-3. **Manually enable AP mode**:
-   - Use web interface: WiFi tab → Enable AP Mode button
-   - Or via API: `POST /api/v3/wifi/ap/enable`
-
-### AP Mode Enabling Unexpectedly
-
-1. **Check auto-enable setting**:
-   ```bash
-   cat config/wifi_config.json | grep auto_enable_ap_mode
-   ```
-
-2. **Disable auto-enable**:
-   ```bash
-   # Edit config file
-   nano config/wifi_config.json
-   # Set "auto_enable_ap_mode": false
-   
-   # Restart service
-   sudo systemctl restart ledmatrix-wifi-monitor
-   ```
-
-3. **Check service logs**:
-   ```bash
-   sudo journalctl -u ledmatrix-wifi-monitor -f
-   ```
-
-## Migration from Old Behavior
-
-If you have an existing installation that was auto-enabling AP mode:
-
-1. The default is now `false` (manual enable)
-2. Existing configs will be updated to include `auto_enable_ap_mode: false`
-3. If you want the old behavior, set `auto_enable_ap_mode: true` in `config/wifi_config.json`

-# AP Mode Manual Enable - Implementation Summary
-
-## Changes Made
-
-### 1. Configuration Option Added
-
-Added `auto_enable_ap_mode` configuration option to `config/wifi_config.json`:
-- **Default value**: `false` (manual enable only)
-- **Purpose**: Controls whether AP mode automatically enables when WiFi/Ethernet disconnect
-- **Migration**: Existing configs automatically get this field set to `false` if missing
-
-### 2. WiFi Manager Updates (`src/wifi_manager.py`)
-
-#### Added Configuration Field
-- Default config now includes `"auto_enable_ap_mode": False`
-- Existing configs are automatically migrated to include this field
-
-#### Updated `check_and_manage_ap_mode()` Method
-- Now checks `auto_enable_ap_mode` setting before auto-enabling AP mode
-- AP mode only auto-enables if:
-  - `auto_enable_ap_mode` is `true` AND
-  - WiFi is NOT connected AND
-  - Ethernet is NOT connected
-- AP mode still auto-disables when WiFi or Ethernet connects (regardless of setting)
-- Manual AP mode (via web UI) works regardless of this setting
-
-### 3. Web Interface API Updates (`web_interface/blueprints/api_v3.py`)
-
-#### Updated `/wifi/status` Endpoint
-- Now returns `auto_enable_ap_mode` setting in response
-
-#### Added `/wifi/ap/auto-enable` GET Endpoint
-- Returns current `auto_enable_ap_mode` setting
-
-#### Added `/wifi/ap/auto-enable` POST Endpoint
-- Allows setting `auto_enable_ap_mode` via API
-- Accepts JSON: `{"auto_enable_ap_mode": true/false}`
-
-### 4. Documentation Updates
-
-- Updated `docs/WIFI_SETUP.md` with new configuration option
-- Created `docs/AP_MODE_MANUAL_ENABLE.md` with comprehensive guide
-- Created `docs/AP_MODE_MANUAL_ENABLE_CHANGES.md` (this file)
-
-## Behavior Changes
-
-### Before
-- AP mode automatically enabled when WiFi disconnected (if Ethernet also disconnected)
-- Could cause SSH to become unavailable after installation
-- No way to disable auto-enable behavior
-
-### After
-- AP mode **does not** automatically enable by default
-- Must be manually enabled through web UI or API
-- Can optionally enable auto-enable via configuration
-- Prevents unexpected AP mode activation
-
-## Migration
-
-### Existing Installations
-
-1. **Automatic Migration**:
-   - When WiFi manager loads config, it automatically adds `auto_enable_ap_mode: false` if missing
-   - No manual intervention required
-
-2. **To Enable Auto-Enable** (if desired):
-   ```bash
-   # Edit config file
-   nano config/wifi_config.json

-# Background Data Service for LEDMatrix
-
-## Overview
-
-The Background Data Service is a new feature that implements background threading for season data fetching to prevent blocking the main display loop. This significantly improves responsiveness and user experience during data fetching operations.
-
-## Key Benefits
-
-- **Non-blocking**: Season data fetching no longer blocks the main display loop
-- **Immediate Response**: Returns cached or partial data immediately while fetching complete data in background
-- **Configurable**: Can be enabled/disabled per sport with customizable settings
-- **Thread-safe**: Uses proper synchronization for concurrent access
-- **Retry Logic**: Automatic retry with exponential backoff for failed requests
-- **Progress Tracking**: Comprehensive logging and statistics
-
-## Architecture
-
-### Core Components
-
-1. **BackgroundDataService**: Main service class managing background threads
-2. **FetchRequest**: Represents individual fetch operations
-3. **FetchResult**: Contains results of fetch operations
-4. **Sport Managers**: Updated to use background service
-
-### How It Works
-
-1. **Cache Check**: First checks for cached data and returns immediately if available
-2. **Background Fetch**: If no cache, starts background thread to fetch complete season data
-3. **Partial Data**: Returns immediate partial data (current/recent games) for quick display
-4. **Completion**: Background fetch completes and caches full dataset
-5. **Future Requests**: Subsequent requests use cached data for instant response
-
-## Configuration
-
-### NFL Configuration Example
-
-```json
-{
-    "nfl_scoreboard": {
-        "enabled": true,
-        "background_service": {
-            "enabled": true,
-            "max_workers": 3,
-            "request_timeout": 30,
-            "max_retries": 3,
-            "priority": 2
-        }
-    }
-}
-```
-
-### Configuration Options
-
-- **enabled**: Enable/disable background service (default: true)
-- **max_workers**: Maximum number of background threads (default: 3)
-- **request_timeout**: HTTP request timeout in seconds (default: 30)
-- **max_retries**: Maximum retry attempts for failed requests (default: 3)
-- **priority**: Request priority (higher = more important, default: 2)
-
-## Implementation Status
-
-### Phase 1: Background Season Data Fetching ✅ COMPLETED
-
-- [x] Created BackgroundDataService class
-- [x] Implemented thread-safe data caching
-- [x] Added retry logic with exponential backoff
-- [x] Modified NFL manager to use background service
-- [x] Added configuration support
-- [x] Created test script
-
-### Phase 2: Rollout to Other Sports (Next Steps)
-
-- [ ] Apply to NCAAFB manager
-- [ ] Apply to NBA manager
-- [ ] Apply to NHL manager
-- [ ] Apply to MLB manager
-- [ ] Apply to other sport managers
-
-## Testing
-
-### Test Script
-
-Run the test script to verify background service functionality:
-
-```bash
-python test_background_service.py
-```
-
-### Test Scenarios
-
-1. **Cache Hit**: Verify immediate return of cached data
-2. **Background Fetch**: Verify non-blocking background data fetching
-3. **Partial Data**: Verify immediate return of partial data during background fetch
-4. **Completion**: Verify background fetch completion and caching
-5. **Subsequent Requests**: Verify cache usage for subsequent requests
-6. **Service Disabled**: Verify fallback to synchronous fetching
-
-### Expected Results
-
-- Initial fetch should return partial data immediately (< 1 second)
-- Background fetch should complete within 10-30 seconds
-- Subsequent fetches should use cache (< 0.1 seconds)
-- No blocking of main display loop
-
-## Performance Impact
-
-### Before Background Service
-- Season data fetch: 10-30 seconds (blocking)
-- Display loop: Frozen during fetch
-- User experience: Poor responsiveness
-
-### After Background Service
-- Initial response: < 1 second (partial data)
-- Background fetch: 10-30 seconds (non-blocking)
-- Display loop: Continues normally
-- User experience: Excellent responsiveness
-
-## Monitoring
-
-### Logs
-
-The service provides comprehensive logging:
-
-```
-[NFL] Background service enabled with 3 workers
-[NFL] Starting background fetch for 2024 season schedule...
-[NFL] Using 15 immediate events while background fetch completes
-[NFL] Background fetch completed for 2024: 256 events
-```
-
-### Statistics
-
-Access service statistics:
-
-```python
-stats = background_service.get_statistics()
-print(f"Total requests: {stats['total_requests']}")
-print(f"Cache hits: {stats['cached_hits']}")
-print(f"Average fetch time: {stats['average_fetch_time']:.2f}s")
-```
-
-## Error Handling
-
-### Automatic Retry
-- Failed requests are automatically retried with exponential backoff
-- Maximum retry attempts are configurable
-- Failed requests are logged with error details
-
-### Fallback Behavior
-- If background service is disabled, falls back to synchronous fetching
-- If background fetch fails, returns partial data if available
-- Graceful degradation ensures system continues to function
-
-## Future Enhancements
-
-### Phase 2 Features
-- Apply to all sport managers
-- Priority-based request queuing
-- Dynamic worker scaling
-- Request batching for efficiency
-
-### Phase 3 Features
-- Real-time data streaming
-- WebSocket support for live updates
-- Advanced caching strategies
-- Performance analytics dashboard
-
-## Troubleshooting
-
-### Common Issues
-
-1. **Background service not starting**
-   - Check configuration: `background_service.enabled = true`
-   - Verify cache manager is properly initialized
-   - Check logs for initialization errors
-
-2. **Slow background fetches**
-   - Increase `request_timeout` in configuration
-   - Check network connectivity
-   - Monitor API rate limits
-
-3. **Memory usage**
-   - Background service automatically cleans up old requests
-   - Adjust `max_workers` if needed
-   - Monitor cache size
-
-### Debug Mode
-
-Enable debug logging for detailed information:
-
-```python
-logging.getLogger('src.background_data_service').setLevel(logging.DEBUG)
-```
-
-## Contributing
-
-When adding background service support to new sport managers:
-
-1. Import the background service
-2. Initialize in `__init__` method
-3. Update data fetching method to use background service
-4. Add configuration options
-5. Test thoroughly
-6. Update documentation

-# Browser Console Errors - Explanation
-
-## Summary
-
-**You don't need to worry about these errors.** They are harmless and don't affect functionality. We've improved error suppression to hide them from the console.
-
-## Error Types
-
-### 1. Permissions-Policy Header Warnings
-
-**Examples:**
-```text
-Error with Permissions-Policy header: Unrecognized feature: 'browsing-topics'.
-Error with Permissions-Policy header: Unrecognized feature: 'run-ad-auction'.
-Error with Permissions-Policy header: Origin trial controlled feature not enabled: 'join-ad-interest-group'.
-```
-
-**What they are:**
-- Browser warnings about experimental/advertising features in HTTP headers
-- These features are not used by our application
-- The browser is just informing you that it doesn't recognize these policy features
-
-**Why they appear:**
-- Some browsers or extensions set these headers
-- They're informational warnings, not actual errors
-- They don't affect functionality at all
-
-**Status:** ✅ **Harmless** - Now suppressed in console
-
-### 2. HTMX insertBefore Errors
-
-**Example:**
-```javascript
-TypeError: Cannot read properties of null (reading 'insertBefore')
-    at At (htmx.org@1.9.10:1:22924)
-```
-
-**What they are:**
-- HTMX library timing/race condition issues
-- Occurs when HTMX tries to swap content but the target element is temporarily null
-- Usually happens during rapid content updates or when elements are being removed/added
-
-**Why they appear:**
-- HTMX dynamically swaps HTML content
-- Sometimes the target element is removed or not yet in the DOM when HTMX tries to insert
-- This is a known issue with HTMX in certain scenarios
-
-**Impact:**
-- ✅ **No functional impact** - HTMX handles these gracefully
-- ✅ **Content still loads correctly** - The swap just fails silently and retries
-- ✅ **User experience unaffected** - Users don't see any issues
-
-**Status:** ✅ **Harmless** - Now suppressed in console
-
-## What We've Done
-
-### Error Suppression Improvements
-
-1. **Enhanced HTMX Error Suppression:**
-   - More comprehensive detection of HTMX-related errors
-   - Catches `insertBefore` errors from HTMX regardless of format
-   - Suppresses timing/race condition errors
-
-2. **Permissions-Policy Warning Suppression:**
-   - Suppresses all Permissions-Policy header warnings
-   - Includes specific feature warnings (browsing-topics, run-ad-auction, etc.)
-   - Prevents console noise from harmless browser warnings
-
-3. **HTMX Validation:**
-   - Added `htmx:beforeSwap` validation to prevent some errors
-   - Checks if target element exists before swapping
-   - Reduces but doesn't eliminate all timing issues
-
-## When to Worry
-
-You should only be concerned about errors if:
-
-1. **Functionality is broken** - If buttons don't work, forms don't submit, or content doesn't load
-2. **Errors are from your code** - Errors in `plugins.html`, `base.html`, or other application files
-3. **Network errors** - Failed API calls or connection issues
-4. **User-visible issues** - Users report problems
-
-## Current Status
-
-✅ **All harmless errors are now suppressed**
-✅ **HTMX errors are caught and handled gracefully**
-✅ **Permissions-Policy warnings are hidden**
-✅ **Application functionality is unaffected**
-
-## Technical Details
-
-### HTMX insertBefore Errors
-
-**Root Cause:**
-- HTMX uses `insertBefore` to swap content into the DOM
-- Sometimes the parent node is null when HTMX tries to insert
-- This happens due to:
-  - Race conditions during rapid updates
-  - Elements being removed before swap completes
-  - Dynamic content loading timing issues
-
-**Why It's Safe:**
-- HTMX has built-in error handling
-- Failed swaps don't break the application
-- Content still loads via other mechanisms
-- No data loss or corruption
-
-### Permissions-Policy Warnings
-
-**Root Cause:**
-- Modern browsers support Permissions-Policy HTTP headers
-- Some features are experimental or not widely supported
-- Browsers warn when they encounter unrecognized features
-
-**Why It's Safe:**
-- We don't use these features
-- The warnings are informational only
-- No security or functionality impact
-
-## Monitoring
-
-If you want to see actual errors (not suppressed ones), you can:
-
-1. **Temporarily disable suppression:**
-   - Comment out the error suppression code in `base.html`
-   - Only do this for debugging
-
-2. **Check browser DevTools:**
-   - Look for errors in the Network tab (actual failures)
-   - Check Console for non-HTMX errors
-   - Monitor user reports for functionality issues
-
-## Conclusion
-
-**These errors are completely harmless and can be safely ignored.** They're just noise in the console that doesn't affect the application's functionality. We've improved the error suppression to hide them so you can focus on actual issues if they arise.

-3. **Test devices** (smartphone, tablet, or laptop)
-4. **Access to Pi** (SSH or direct access)
-
-## Important: Before Testing
-
-**⚠️ Make sure you have a way to reconnect!**
-
-Before starting testing, ensure you have:
-- **Ethernet cable** (if available) as backup connection
-- **SSH access** via another method (Ethernet, direct connection)
-- **Physical access** to Pi (keyboard/monitor) as last resort
-- **Your WiFi credentials** saved/noted down
-
-**If testing fails, see:** [Reconnecting After Testing](RECONNECT_AFTER_CAPTIVE_PORTAL_TESTING.md)
-
-**Quick recovery script:** `sudo ./scripts/emergency_reconnect.sh`
-
-## Pre-Testing Setup
-
-### 0. Verify WiFi is Ready (IMPORTANT!)
-
-**⚠️ CRITICAL: Run this BEFORE disconnecting Ethernet!**
-
-```bash
-sudo ./scripts/verify_wifi_before_testing.sh
-```
-
-This script will verify:
-- WiFi interface exists and is enabled
-- WiFi can scan for networks
-- You have saved WiFi connections (for reconnecting)
-- Required services are ready
-- Current network status
-
-**Do NOT disconnect Ethernet until this script passes all checks!**
-
-### 1. Ensure WiFi Monitor Service is Running
-
-```bash
-sudo systemctl status ledmatrix-wifi-monitor
-```
-
-If not running:
-```bash
-sudo systemctl start ledmatrix-wifi-monitor
-sudo systemctl enable ledmatrix-wifi-monitor
-```
-
-### 2. Disconnect Pi from WiFi/Ethernet
-
-**⚠️ Only do this AFTER running the verification script!**
-
-To test captive portal, the Pi should NOT be connected to any network:
-
-```bash
-# First, verify WiFi is ready (see step 0 above)
-sudo ./scripts/verify_wifi_before_testing.sh
-
-# Check current network status
-nmcli device status
-
-# Disconnect WiFi (if connected)
-sudo nmcli device disconnect wlan0
-
-# Disconnect Ethernet (if connected)
-# Option 1: Unplug Ethernet cable (safest)
-# Option 2: Via command (if you're sure WiFi works):
-sudo nmcli device disconnect eth0
-
-# Verify disconnection
-nmcli device status
-# Both should show "disconnected" or "unavailable"
-```
-
-### 3. Enable AP Mode
-
-You can enable AP mode manually or wait for it to auto-enable (if `auto_enable_ap_mode` is true):
-
-**Manual enable via web interface:**
-- Access web interface at `http://<pi-ip>:5000` (if still accessible)
-- Go to WiFi tab
-- Click "Enable AP Mode"
-
-**Manual enable via command line:**
-```bash
-python3 -c "from src.wifi_manager import WiFiManager; wm = WiFiManager(); print(wm.enable_ap_mode())"
-```
-
-**Or via API:**
-```bash
-curl -X POST http://localhost:5000/api/v3/wifi/ap/enable
-```
-
-### 4. Verify AP Mode is Active
-
-```bash
-# Check hostapd service
-sudo systemctl status hostapd
-
-# Check dnsmasq service
-sudo systemctl status dnsmasq
-
-# Check if wlan0 is in AP mode
-iwconfig wlan0
-# Should show "Mode:Master"
-
-# Check IP address
-ip addr show wlan0
-# Should show 192.168.4.1
-```
-
-### 5. Verify DNSMASQ Configuration
-
-```bash
-# Check dnsmasq config
-sudo cat /etc/dnsmasq.conf
-
-# Should contain:
-# - address=/#/192.168.4.1
-# - address=/captive.apple.com/192.168.4.1
-# - address=/connectivitycheck.gstatic.com/192.168.4.1
-# - address=/www.msftconnecttest.com/192.168.4.1
-# - address=/detectportal.firefox.com/192.168.4.1
-```
-
-### 6. Verify Web Interface is Running
-
-```bash
-# Check if web service is running
-sudo systemctl status ledmatrix-web
-
-# Or check if Flask app is running
-ps aux | grep "web_interface"

-
-## Troubleshooting
-
-### Issue: DNS Not Redirecting
-
-**Symptoms:** DNS queries resolve to actual IPs, not 192.168.4.1
-
-**Solutions:**
-1. Check dnsmasq config:
-   ```bash
-   sudo cat /etc/dnsmasq.conf | grep address
-   ```
-2. Restart dnsmasq:
-   ```bash
-   sudo systemctl restart dnsmasq
-   ```
-3. Check dnsmasq logs:
-   ```bash
-   sudo journalctl -u dnsmasq -n 50
-   ```
-
-### Issue: HTTP Not Redirecting
-
-**Symptoms:** Browser shows actual websites instead of redirecting
-
-**Solutions:**
-1. Check if AP mode is active:
-   ```bash
-   python3 -c "from src.wifi_manager import WiFiManager; wm = WiFiManager(); print(wm._is_ap_mode_active())"
-   ```
-2. Check Flask app logs for errors
-3. Verify web interface is running on port 5000
-4. Test redirect middleware manually:
-   ```bash
-   curl -I http://192.168.4.1:5000/google.com
-   # Should return 302 redirect
-   ```
-
-### Issue: Captive Portal Not Detected by Device
-
-**Symptoms:** Device doesn't show sign-in notification/popup
-
-**Solutions:**
-1. Verify detection endpoints are accessible:
-   ```bash
-   curl http://192.168.4.1:5000/hotspot-detect.html
-   curl http://192.168.4.1:5000/generate_204
-   ```
-2. Try manually opening browser and visiting any website
-3. Some devices require specific responses - check endpoint implementations
-4. Clear device's network settings and reconnect
-
-### Issue: Infinite Redirect Loop
-
-**Symptoms:** Browser keeps redirecting in a loop
-
-**Solutions:**
-1. Check that `/v3` path is in allowed_paths list
-2. Verify redirect middleware logic in `app.py`
-3. Check Flask logs for errors
-4. Ensure WiFi API endpoints are not being redirected
-
-### Issue: AP Mode Not Enabling
-
-**Symptoms:** Can't connect to "LEDMatrix-Setup" network
-
-**Solutions:**
-1. Check WiFi monitor service:
-   ```bash
-   sudo systemctl status ledmatrix-wifi-monitor
-   ```
-2. Check WiFi config:
-   ```bash
-   cat config/wifi_config.json
-   ```
-3. Manually enable AP mode:
-   ```bash
-   python3 -c "from src.wifi_manager import WiFiManager; wm = WiFiManager(); print(wm.enable_ap_mode())"
-   ```
-4. Check hostapd logs:
-   ```bash
-   sudo journalctl -u hostapd -n 50
-   ```

-
-echo -e "\nTesting complete!"
-```
-
-Make it executable and run:
-```bash
-chmod +x test_captive_portal.sh
-./test_captive_portal.sh
-```
-
-## Notes
-
-- **Port Number:** The web interface runs on port 5000 by default. If you've changed this, update all URLs accordingly.
-- **Network Range:** The AP uses 192.168.4.0/24 network. If you need a different range, update both hostapd and dnsmasq configs.
-- **Password:** Default AP password is `ledmatrix123`. Change it in `config/wifi_config.json` if needed.
-- **Testing on Same Device:** If testing from the Pi itself, you'll need a second device to connect to the AP network.

-# Captive Portal Troubleshooting Guide
-
-## Problem: Can't Access Web Interface When Connected to AP
-
-If you've connected to the "LEDMatrix-Setup" WiFi network but can't access the web interface, follow these steps:
-
-## Quick Checks
-
-### 1. Verify Web Server is Running
-
-```bash
-sudo systemctl status ledmatrix-web
-```
-
-If not running:
-```bash
-sudo systemctl start ledmatrix-web
-sudo systemctl enable ledmatrix-web
-```
-
-### 2. Try Direct IP Access
-
-On your phone/device, try accessing the web interface directly:
-- **http://192.168.4.1:5000/v3**
-- **http://192.168.4.1:5000**
-
-The port `:5000` is required - the web server runs on port 5000, not the standard port 80.
-
-### 3. Check DNS Resolution
-
-The captive portal uses DNS redirection. Try accessing:
-- **http://captive.apple.com** (should redirect to setup page)
-- **http://www.google.com** (should redirect to setup page)
-- **http://192.168.4.1:5000** (direct access - should always work)
-
-### 4. Verify AP Mode is Active
-
-```bash
-sudo systemctl status hostapd
-sudo systemctl status dnsmasq
-ip addr show wlan0 | grep 192.168.4.1
-```
-
-All should be active/running.
-
-### 5. Check Firewall
-
-If you have a firewall enabled, ensure port 5000 is open:
-
-```bash
-# For UFW
-sudo ufw allow 5000/tcp
-
-# For iptables
-sudo iptables -A INPUT -p tcp --dport 5000 -j ACCEPT
-```
-
-## Common Issues
-
-### Issue: "Can't connect to server" or "Connection refused"
-
-**Cause**: Web server not running or not listening on the correct interface.
-
-**Solution**:
-```bash
-sudo systemctl start ledmatrix-web
-sudo systemctl status ledmatrix-web
-```
-
-### Issue: DNS not resolving / "Server not found"
-
-**Cause**: dnsmasq not running or DNS redirection not configured.
-
-**Solution**:
-```bash
-# Check dnsmasq
-sudo systemctl status dnsmasq
-
-# Restart AP mode
-cd ~/LEDMatrix
-python3 -c "from src.wifi_manager import WiFiManager; wm = WiFiManager(); wm.disable_ap_mode(); wm.enable_ap_mode()"
-```
-
-### Issue: Page loads but shows "Connection Error" or blank page
-
-**Cause**: Web server is running but Flask app has errors.
-
-**Solution**:
-```bash
-# Check web server logs
-sudo journalctl -u ledmatrix-web -n 50 --no-pager
-
-# Restart web server
-sudo systemctl restart ledmatrix-web
-```
-
-### Issue: Phone connects but browser doesn't open automatically
-
-**Cause**: Some devices don't automatically detect captive portals.
-
-**Solution**: Manually open browser and go to:
-- **http://192.168.4.1:5000/v3**
-- Or try: **http://captive.apple.com** (iOS) or **http://www.google.com** (Android)
-
-## Testing Steps
-
-1. **Disconnect Ethernet** from Pi
-2. **Wait 30 seconds** for AP mode to start
-3. **Connect phone** to "LEDMatrix-Setup" network (password: `ledmatrix123`)
-4. **Open browser** on phone
-5. **Try these URLs**:
-   - `http://192.168.4.1:5000/v3` (direct access)
-   - `http://captive.apple.com` (iOS captive portal detection)
-   - `http://www.google.com` (should redirect)
-
-## Automated Troubleshooting
-
-Run the troubleshooting script:
-
-```bash
-cd ~/LEDMatrix
-./scripts/troubleshoot_captive_portal.sh
-```
-
-This will check all components and provide specific fixes.
-
-## Manual AP Mode Test
-
-To manually test AP mode (bypassing Ethernet check):
-
-```bash
-cd ~/LEDMatrix
-python3 -c "
-from src.wifi_manager import WiFiManager
-wm = WiFiManager()
-
-# Temporarily disconnect Ethernet check
-# (This is for testing only - normally AP won't start with Ethernet)
-print('Enabling AP mode...')
-result = wm.enable_ap_mode()
-print('Result:', result)
-"
-```
-
-**Note**: This will fail if Ethernet is connected (by design). You must disconnect Ethernet first.
-
-## Still Not Working?
-
-1. **Check all services**:
-   ```bash
-   sudo systemctl status ledmatrix-web hostapd dnsmasq ledmatrix-wifi-monitor
-   ```
-
-2. **Check logs**:
-   ```bash
-   sudo journalctl -u ledmatrix-web -f
-   sudo journalctl -u ledmatrix-wifi-monitor -f
-   ```
-
-3. **Verify network configuration**:
-   ```bash
-   ip addr show wlan0
-   ip route show
-   ```
-
-4. **Test from Pi itself**:
-   ```bash
-   curl http://192.168.4.1:5000/v3
-   ```
-
-If it works from the Pi but not from your phone, it's likely a DNS or firewall issue.

-# Implementation Plan: Fix Config Schema Validation Issues
-
-Based on audit results showing 186 issues across 20 plugins.
-
-## Overview
-
-Three priority fixes identified from audit:
-1. **Priority 1 (HIGH)**: Remove core properties from required array - will fix ~150 issues
-2. **Priority 2 (MEDIUM)**: Verify default merging logic - will fix remaining required field issues
-3. **Priority 3 (LOW)**: Calendar plugin schema cleanup - will fix 3 extra field warnings
-
-## Priority 1: Remove Core Properties from Required Array
-
-### Problem
-Core properties (`enabled`, `display_duration`, `live_priority`) are system-managed but listed in schema `required` arrays. SchemaManager injects them into properties but doesn't remove them from `required`, causing validation failures.
-
-### Solution
-**File**: `src/plugin_system/schema_manager.py`
-**Location**: `validate_config_against_schema()` method, after line 295
-
-### Implementation Steps
-
-1. **Add code to remove core properties from required array**:
-   ```python
-   # After injecting core properties (around line 295), add:
-   # Remove core properties from required array (they're system-managed)
-   if "required" in enhanced_schema:
-       core_prop_names = list(core_properties.keys())
-       enhanced_schema["required"] = [
-           field for field in enhanced_schema["required"] 
-           if field not in core_prop_names
-       ]
-   ```
-
-2. **Add logging for debugging** (optional but helpful):
-   ```python
-   if "required" in enhanced_schema and core_prop_names:
-       removed_from_required = [
-           field for field in enhanced_schema.get("required", [])
-           if field in core_prop_names
-       ]
-       if removed_from_required and plugin_id:
-           self.logger.debug(
-               f"Removed core properties from required array for {plugin_id}: {removed_from_required}"
-           )
-   ```
-
-3. **Test the fix**:
-   - Run audit script: `python scripts/audit_plugin_configs.py`
-   - Expected: Issue count drops from 186 to ~30-40
-   - All "enabled" related errors should be eliminated
-
-### Expected Outcome
-- All 20 plugins should no longer fail validation due to missing `enabled` field
-- ~150 issues resolved (all enabled-related validation errors)
-
-## Priority 2: Verify Default Merging Logic
-
-### Problem
-Some plugins have required fields with defaults that should be applied before validation. Need to verify the default merging happens correctly and handles nested objects.
-
-### Solution
-**File**: `web_interface/blueprints/api_v3.py`
-**Location**: `save_plugin_config()` method, around lines 3218-3221
-
-### Implementation Steps
-
-1. **Review current default merging logic**:
-   - Check that `merge_with_defaults()` is called before validation (line 3220)
-   - Verify it's called after preserving enabled state but before validation
-
-2. **Verify merge_with_defaults handles nested objects**:
-   - Check `src/plugin_system/schema_manager.py` → `merge_with_defaults()` method
-   - Ensure it recursively merges nested objects (it does use deep_merge)
-   - Test with plugins that have nested required fields
-
-3. **Check if defaults are applied for nested required fields**:
-   - Review how `generate_default_config()` extracts defaults from nested schemas
-   - Verify nested required fields with defaults are included
-
-4. **Test with problematic plugins**:
-   - `ledmatrix-weather`: required fields `api_key`, `location_city` (check if defaults exist)
-   - `mqtt-notifications`: required field `mqtt` object (check if default exists)
-   - `text-display`: required field `text` (check if default exists)
-   - `ledmatrix-music`: required field `preferred_source` (check if default exists)
-
-5. **If defaults don't exist in schemas**:
-   - Either add defaults to schemas, OR
-   - Make fields optional in schemas if they're truly optional
-
-### Expected Outcome
-- Plugins with required fields that have schema defaults should pass validation
-- Issue count further reduced from ~30-40 to ~5-10
-
-## Priority 3: Calendar Plugin Schema Cleanup
-
-### Problem
-Calendar plugin config has fields not in schema:
-- `show_all_day` (config) but schema has `show_all_day_events` (field name mismatch)
-- `date_format` (not in schema, not used in manager.py)
-- `time_format` (not in schema, not used in manager.py)
-
-### Investigation Results
-- Schema defines: `show_all_day_events` (boolean, default: true)
-- Manager.py uses: `show_all_day_events` (line 82: `config.get('show_all_day_events', True)`)
-- Config has: `show_all_day` (wrong field name - should be `show_all_day_events`)
-- `date_format` and `time_format` appear to be deprecated (not used in manager.py)
-
-### Solution
-
-**File**: `config/config.json` → `calendar` section
-
-### Implementation Steps
-
-1. **Fix field name mismatch**:
-   - Rename `show_all_day` → `show_all_day_events` in config.json
-   - This matches the schema and manager.py code
-
-2. **Remove deprecated fields**:
-   - Remove `date_format` from config (not used in code)
-   - Remove `time_format` from config (not used in code)
-
-3. **Alternative (if fields are needed)**: Add `date_format` and `time_format` to schema
-   - Only if these fields should be supported
-   - Check if they're used anywhere else in the codebase
-
-4. **Test calendar plugin**:
-   - Run audit for calendar plugin specifically
-   - Verify no extra field warnings remain
-   - Test calendar plugin functionality to ensure it still works
-
-### Expected Outcome
-- Calendar plugin shows 0 extra field warnings
-- Final issue count: ~3-5 (only edge cases remain)
-
-## Testing Strategy
-
-### After Each Priority Fix
-
-1. **Run local audit**:
-   ```bash
-   python scripts/audit_plugin_configs.py
-   ```
-
-2. **Check issue count reduction**:
-   - Priority 1: Should drop from 186 to ~30-40
-   - Priority 2: Should drop from ~30-40 to ~5-10
-   - Priority 3: Should drop from ~5-10 to ~3-5
-
-3. **Review specific plugin results**:
-   ```bash
-   python scripts/audit_plugin_configs.py --plugin <plugin-id>
-   ```
-
-### After All Fixes
-
-1. **Full audit run**:
-   ```bash
-   python scripts/audit_plugin_configs.py
-   ```
-
-2. **Deploy to Pi**:
-   ```bash
-   ./scripts/deploy_to_pi.sh src/plugin_system/schema_manager.py web_interface/blueprints/api_v3.py
-   ```
-
-3. **Run audit on Pi**:
-   ```bash
-   ./scripts/run_audit_on_pi.sh
-   ```
-
-4. **Manual web interface testing**:
-   - Access each problematic plugin's config page
-   - Try saving configuration
-   - Verify no validation errors appear
-   - Check that configs save successfully
-
-## Success Criteria
-
-- [ ] Priority 1: All "enabled" related validation errors eliminated
-- [ ] Priority 1: Issue count reduced from 186 to ~30-40
-- [ ] Priority 2: Plugins with required fields + defaults pass validation
-- [ ] Priority 2: Issue count reduced to ~5-10
-- [ ] Priority 3: Calendar plugin extra field warnings resolved
-- [ ] Priority 3: Final issue count at ~3-5 (only edge cases)
-- [ ] All fixes work on Pi (not just local)
-- [ ] Web interface saves configs without validation errors
-
-## Files to Modify
-
-1. `src/plugin_system/schema_manager.py` - Remove core properties from required array
-2. `plugins/calendar/config_schema.json` OR `config/config.json` - Calendar cleanup (if needed)
-3. `web_interface/blueprints/api_v3.py` - May need minor adjustments for default merging (if needed)
-
-## Risk Assessment
-
-**Priority 1**: Low risk - Only affects validation logic, doesn't change behavior
-**Priority 2**: Low risk - Only ensures defaults are applied (already intended behavior)
-**Priority 3**: Very low risk - Only affects calendar plugin, cosmetic issue
-
-All changes are backward compatible and improve the system rather than changing core functionality.

-# Debug: Service Deactivated After Installing Dependencies
-
-## What Happened
-
-The service:
-1. ✅ Started successfully
-2. ✅ Installed dependencies
-3. ❌ Deactivated successfully (exited cleanly)
-
-This means it finished running but didn't actually launch the Flask app.
-
-## Most Likely Cause
-
-**`web_display_autostart` is probably set to `false` in your config.json**
-
-The service is designed to exit gracefully if this is false - it won't even try to start Flask.
-
-## Commands to Run RIGHT NOW
-
-### 1. Check the full logs to see what it said before exiting:
-```bash
-sudo journalctl -u ledmatrix-web -n 200 --no-pager | grep -A 5 -B 5 "web_display_autostart\|Configuration\|Launching\|will not"
-```
-
-This will show you if it said something like:
-- "Configuration 'web_display_autostart' is false or not set. Web interface will not be started."
-
-### 2. Check your config.json:
-```bash
-cat ~/LEDMatrix/config/config.json | grep web_display_autostart
-```
-
-### 3. If it's false or missing, set it to true:
-```bash
-nano ~/LEDMatrix/config/config.json
-```
-
-Find the line with `web_display_autostart` and change it to:
-```json
-"web_display_autostart": true,
-```
-
-If the line doesn't exist, add it near the top of the file (after the opening `{`):
-```json
-{
-  "web_display_autostart": true,
-  ... rest of config ...
-}
-```
-
-### 4. After fixing the config, restart the service:
-```bash
-sudo systemctl restart ledmatrix-web
-```
-
-### 5. Watch it start up:
-```bash
-sudo journalctl -u ledmatrix-web -f
-```
-
-You should see:
-- "Configuration 'web_display_autostart' is true. Starting web interface..."
-- "Dependencies installed successfully"
-- "Launching web interface v3: ..."
-- Flask starting up
-
-## Alternative: View ALL Recent Logs
-
-To see everything that happened:
-```bash
-sudo journalctl -u ledmatrix-web --since "5 minutes ago" --no-pager
-```
-
-This will show you the complete log including what happened after dependency installation.

-# Form Validation Fixes - Preventing "Invalid Form Control" Errors
-
-## Problem
-
-Browser was throwing errors: "An invalid form control with name='...' is not focusable" when:
-- Number inputs had values outside their min/max constraints
-- These fields were in collapsed/hidden nested sections
-- Browser couldn't focus hidden invalid fields to show validation errors
-
-## Root Cause
-
-1. **Value Clamping Missing**: Number inputs were generated with values that didn't respect min/max constraints
-2. **HTML5 Validation on Hidden Fields**: Browser validation tried to validate hidden fields but couldn't focus them
-3. **No Pre-Submit Validation**: Forms didn't fix invalid values before submission
-
-## Fixes Applied
-
-### 1. Plugin Configuration Form (`plugins.html`)
-
-**File**: `web_interface/templates/v3/partials/plugins.html`
-
-**Changes**:
-- ✅ Added value clamping in `generateFieldHtml()` (lines 1825-1844)
-  - Clamps values to min/max when generating number inputs
-  - Uses default value if provided
-  - Ensures all generated fields have valid values
-- ✅ Added `novalidate` attribute to form (line 1998)
-- ✅ Added pre-submit validation fix in `handlePluginConfigSubmit()` (lines 1518-1533)
-  - Fixes any invalid values before processing form data
-  - Prevents "invalid form control is not focusable" errors
-
-### 2. Plugin Config in Base Template (`base.html`)
-
-**File**: `web_interface/templates/v3/base.html`
-
-**Changes**:
-- ✅ Added value clamping in number input generation (lines 1386-1407)
-  - Same logic as plugins.html
-  - Clamps values to min/max constraints
-- ✅ Fixed display_duration input (line 1654)
-  - Uses `Math.max(5, Math.min(300, value))` to clamp value
-- ✅ Added global `fixInvalidNumberInputs()` function (lines 2409-2425)
-  - Can be called from any form's onsubmit handler
-  - Fixes invalid number inputs before submission
-
-### 3. Display Settings Form (`display.html`)
-
-**File**: `web_interface/templates/v3/partials/display.html`
-
-**Changes**:
-- ✅ Added `novalidate` attribute to form (line 13)
-- ✅ Added `onsubmit="fixInvalidNumberInputs(this); return true;"` (line 14)
-- ✅ Added local `fixInvalidNumberInputs()` function as fallback (lines 260-278)
-
-### 4. Durations Form (`durations.html`)
-
-**File**: `web_interface/templates/v3/partials/durations.html`
-
-**Changes**:
-- ✅ Added `novalidate` attribute to form (line 13)
-- ✅ Added `onsubmit="fixInvalidNumberInputs(this); return true;"` (line 14)
-
-## Implementation Details
-
-### Value Clamping Logic
-
-```javascript
-// Ensure value respects min/max constraints
-let fieldValue = value !== undefined ? value : (prop.default !== undefined ? prop.default : '');
-if (fieldValue !== '' && fieldValue !== undefined && fieldValue !== null) {
-    const numValue = typeof fieldValue === 'string' ? parseFloat(fieldValue) : fieldValue;
-    if (!isNaN(numValue)) {
-        // Clamp value to min/max if constraints exist
-        if (prop.minimum !== undefined && numValue < prop.minimum) {
-            fieldValue = prop.minimum;
-        } else if (prop.maximum !== undefined && numValue > prop.maximum) {
-            fieldValue = prop.maximum;
-        } else {
-            fieldValue = numValue;
-        }
-    }
-}
-```
-
-### Pre-Submit Validation Fix
-
-```javascript
-// Fix invalid hidden fields before submission
-const allInputs = form.querySelectorAll('input[type="number"]');
-allInputs.forEach(input => {
-    const min = parseFloat(input.getAttribute('min'));
-    const max = parseFloat(input.getAttribute('max'));
-    const value = parseFloat(input.value);
-    
-    if (!isNaN(value)) {
-        if (!isNaN(min) && value < min) {
-            input.value = min;
-        } else if (!isNaN(max) && value > max) {
-            input.value = max;
-        }
-    }
-});
-```
-
-## Files Modified
-
-1. ✅ `web_interface/templates/v3/partials/plugins.html`
-   - Value clamping in field generation
-   - `novalidate` on forms
-   - Pre-submit validation fix
-
-2. ✅ `web_interface/templates/v3/base.html`

-   - Local fallback function
-
-4. ✅ `web_interface/templates/v3/partials/durations.html`
-   - `novalidate` on form
-   - `onsubmit` handler
-
-## Prevention Strategy
-
-### For Future Forms
-
-1. **Always clamp number input values** when generating forms:
-   ```javascript
-   // Clamp value to min/max
-   if (min !== undefined && value < min) value = min;
-   if (max !== undefined && value > max) value = max;
-   ```
-
-2. **Add `novalidate` to forms** that use custom validation:
-   ```html
-   <form novalidate onsubmit="fixInvalidNumberInputs(this); return true;">
-   ```
-
-3. **Use the global helper** for pre-submit validation:
-   ```javascript
-   window.fixInvalidNumberInputs(form);
-   ```
-
-4. **Check for hidden fields** - If fields can be hidden (collapsed sections), ensure:
-   - Values are valid when fields are generated
-   - Pre-submit validation fixes any remaining issues
-   - Form has `novalidate` to prevent HTML5 validation
-
-## Testing
-
-### Test Cases
-
-1. ✅ Number input with value=0, min=60 → Should clamp to 60
-2. ✅ Number input with value=1000, max=600 → Should clamp to 600
-3. ✅ Hidden field with invalid value → Should be fixed on submit
-4. ✅ Form submission with invalid values → Should fix before submit
-5. ✅ Nested sections with number inputs → Should work correctly
-
-### Manual Testing
-
-1. Open plugin configuration with nested sections
-2. Collapse a section with number inputs
-3. Try to submit form → Should work without errors
-4. Check browser console → Should have no validation errors
-
-## Related Issues

-- **Issue**: "An invalid form control with name='...' is not focusable"

-- **Solution**: Value clamping + pre-submit validation + `novalidate`
-
-## Notes
-
-- We use `novalidate` because we do server-side validation anyway
-- The pre-submit fix is a safety net for any edge cases
-- Value clamping at generation time prevents most issues
-- All fixes are backward compatible

-# Web UI Reliability Improvements - Integration Complete
-
-## Summary
-
-Successfully integrated the new reliability infrastructure into the web UI's plugin and configuration management system. All critical endpoints now use the new infrastructure for improved reliability, debuggability, and maintainability.
-
-## What Was Integrated
-
-### 1. Atomic Configuration Saves ✅
-
-**Integrated Into:**
-- `save_plugin_config()` - Plugin configuration saves
-- `save_main_config()` - Main configuration saves
-- `save_schedule_config()` - Schedule configuration saves
-
-**Benefits:**
-- Automatic backups before each save (keeps last 5)
-- Atomic file writes prevent corruption
-- Automatic rollback on validation failure
-- Can restore from any backup
-
-**Usage:**
-```python
-# Automatic - happens in background
-result = config_manager.save_config_atomic(new_config, create_backup=True)
-
-# Manual rollback if needed
-config_manager.rollback_config()
-```
-
-### 2. Plugin Operation Queue ✅
-
-**Integrated Into:**
-- `install_plugin()` - Queues installation operations
-- `update_plugin()` - Queues update operations
-- `uninstall_plugin()` - Queues uninstall operations
-
-**New Endpoints:**
-- `GET /api/v3/plugins/operation/<operation_id>` - Check operation status
-- `GET /api/v3/plugins/operation/history` - Get operation history
-
-**Benefits:**
-- Prevents concurrent operations on same plugin
-- Serializes operations to avoid conflicts
-- Tracks operation status and progress
-- Operation history for debugging
-
-**Usage:**
-```python
-# Operations are automatically queued
-operation_id = operation_queue.enqueue_operation(
-    OperationType.INSTALL,
-    plugin_id,
-    operation_callback=install_callback
-)
-
-# Check status
-status = operation_queue.get_operation_status(operation_id)
-```
-
-### 3. Structured Error Handling ✅
-
-**Integrated Into:**
-- All plugin management endpoints
-- All configuration endpoints
-- All new endpoints
-
-**Benefits:**
-- Consistent error response format
-- Error codes for programmatic handling
-- Suggested fixes in error responses
-- Detailed context for debugging
-
-**Error Response Format:**
-```json
-{
-  "status": "error",
-  "error_code": "PLUGIN_NOT_FOUND",
-  "error_category": "plugin",
-  "message": "Plugin not found",
-  "details": "...",
-  "suggested_fixes": ["Check plugin ID", "Refresh plugin list"],
-  "context": {"plugin_id": "..."}
-}
-```
-
-### 4. Operation History ✅
-
-**Integrated Into:**
-- All plugin operations (install, update, uninstall, toggle, configure)
-- Automatically tracks all operations
-- Persisted to `data/operation_history.json`
-
-**Benefits:**
-- Complete audit trail
-- Debugging support
-- Operation tracking
-
-### 5. State Management ✅
-
-**Integrated Into:**
-- `toggle_plugin()` - Updates state on enable/disable
-- `install_plugin()` - Records installation state
-- `uninstall_plugin()` - Removes state on uninstall
-
-**New Endpoints:**
-- `GET /api/v3/plugins/state` - Get plugin state(s)
-- `POST /api/v3/plugins/state/reconcile` - Reconcile state inconsistencies
-
-**Benefits:**
-- Single source of truth for plugin state
-- State change notifications
-- State persistence
-- Automatic state reconciliation
-
-### 6. State Reconciliation ✅
-
-**New Endpoint:**
-- `POST /api/v3/plugins/state/reconcile` - Detect and fix state inconsistencies
-
-**Benefits:**
-- Detects inconsistencies between config, manager, disk, and state manager
-- Auto-fixes safe inconsistencies
-- Reports manual fix requirements
-
-## Integration Details
-
-### Files Modified
-
-1. **`web_interface/app.py`**
-   - Initialized operation queue
-   - Initialized state manager
-   - Initialized operation history

-
-## Testing
-
-All code passes linting. To test:
-
-1. **Test atomic config saves:**
-   ```bash
-   # Save config - should create backup
-   curl -X POST http://localhost:5000/api/v3/plugins/config \
-     -H "Content-Type: application/json" \
-     -d '{"plugin_id": "test", "config": {"enabled": true}}'
-   
-   # List backups
-   # (Check config/backups/ directory)
-   ```
-
-2. **Test operation queue:**
-   ```bash
-   # Install plugin - returns operation_id
-   curl -X POST http://localhost:5000/api/v3/plugins/install \
-     -H "Content-Type: application/json" \
-     -d '{"plugin_id": "test-plugin"}'
-   
-   # Check operation status
-   curl http://localhost:5000/api/v3/plugins/operation/<operation_id>
-   ```
-
-3. **Test state reconciliation:**
-   ```bash
-   # Reconcile state
-   curl -X POST http://localhost:5000/api/v3/plugins/state/reconcile
-   ```
-
-## Data Files Created
-
-- `data/plugin_operations.json` - Operation queue history
-- `data/plugin_state.json` - Plugin state persistence
-- `data/operation_history.json` - Operation history/audit log

-# Nested Config Schema Implementation - Complete
-
-## Summary
-
-The plugin manager now fully supports **nested config schemas**, allowing complex plugins to organize their configuration options into logical, collapsible sections in the web interface.
-
-## What Was Implemented
-
-### 1. Core Functionality ✅
-
-**Updated Files:**
-- `web_interface/templates/v3/partials/plugins.html`
-
-**New Features:**
-- Recursive form generation for nested objects
-- Collapsible sections with smooth animations
-- Dot notation for form field names (e.g., `nfl.display_modes.show_live`)
-- Automatic conversion between flat form data and nested JSON
-- Support for unlimited nesting depth
-
-### 2. Helper Functions ✅
-
-Added to `plugins.html`:
-
-- **`getSchemaPropertyType(schema, path)`** - Find property type using dot notation
-- **`dotToNested(obj)`** - Convert flat dot notation to nested objects
-- **`collectBooleanFields(schema, prefix)`** - Recursively find all boolean fields
-- **`flattenConfig(obj, prefix)`** - Flatten nested config for form display
-- **`generateFieldHtml(key, prop, value, prefix)`** - Recursively generate form fields
-- **`toggleNestedSection(sectionId)`** - Toggle collapse/expand of nested sections
-
-### 3. UI Enhancements ✅
-
-**CSS Styling Added:**
-- Smooth transitions for expand/collapse
-- Visual hierarchy with indentation
-- Gray background for nested sections to differentiate from main form
-- Hover effects on section headers
-- Chevron icons that rotate on toggle
-- Responsive design for nested sections
-
-### 4. Backward Compatibility ✅
-
-**Fully Compatible:**
-- All 18 existing plugins with flat schemas work without changes
-- Mixed mode supported (flat and nested properties in same schema)
-- No backend API changes required
-- Existing configs load and save correctly
-
-### 5. Documentation ✅
-
-**Created Files:**
-- `docs/NESTED_CONFIG_SCHEMAS.md` - Complete user guide
-- `plugin-repos/ledmatrix-football-scoreboard/config_schema_nested_example.json` - Example nested schema
-
-## Why It Wasn't Supported Before
-
-Simply put: **nobody implemented it yet**. The original `generateFormFromSchema()` function only handled flat properties - it had no handler for `type: 'object'` which indicates nested structures. All existing plugins used flat schemas with prefixed names (e.g., `nfl_enabled`, `nfl_show_live`, etc.).
-
-## Technical Details
-
-### How It Works
-
-1. **Schema Definition**: Plugin defines nested objects using `type: "object"` with nested `properties`
-2. **Form Generation**: `generateFieldHtml()` recursively creates collapsible sections for nested objects
-3. **Form Submission**: Form data uses dot notation (`nfl.enabled`) which is converted to nested JSON (`{nfl: {enabled: true}}`)
-4. **Config Storage**: Stored as proper nested JSON objects in `config.json`
-
-### Example Transformation
-
-**Flat Schema (Before):**
-```json
-{
-  "nfl_enabled": true,
-  "nfl_show_live": true,
-  "nfl_favorite_teams": ["TB", "DAL"]
-}
-```
-
-**Nested Schema (After):**
-```json
-{
-  "nfl": {
-    "enabled": true,
-    "show_live": true,
-    "favorite_teams": ["TB", "DAL"]
-  }
-}
-```
-
-### Field Name Mapping
-
-Form fields use dot notation internally:
-- `nfl.enabled` → `{nfl: {enabled: true}}`
-- `nfl.display_modes.show_live` → `{nfl: {display_modes: {show_live: true}}}`
-- `ncaa_fb.game_limits.recent_games_to_show` → `{ncaa_fb: {game_limits: {recent_games_to_show: 5}}}`
-
-## Benefits
-
-### For Plugin Developers
-- **Better organization** - Group related settings logically
-- **Cleaner code** - Access config with natural nesting: `config["nfl"]["enabled"]`
-- **Easier maintenance** - Related settings are together
-- **Scalability** - Handle 50+ options without overwhelming users
-
-### For Users
-- **Less overwhelming** - Collapsible sections hide complexity
-- **Easier navigation** - Find settings quickly in logical groups
-- **Better understanding** - Clear hierarchy shows relationships
-- **Cleaner UI** - Organized sections vs. endless list
-
-## Examples
-
-### Football Plugin Comparison
-
-**Before (Flat - 32 properties):**
-All properties in one long list:
-- `nfl_enabled`
-- `nfl_favorite_teams`
-- `nfl_show_live`
-- `nfl_show_recent`
-- `nfl_show_upcoming`
-- ... (27 more)
-
-**After (Nested - Same 32 properties):**
-Organized into 2 main sections:
-- **NFL Settings** (collapsed)
-  - **Display Modes** (collapsed)
-  - **Game Limits** (collapsed)
-  - **Display Options** (collapsed)
-  - **Filtering** (collapsed)
-- **NCAA Football Settings** (collapsed)
-  - Same nested structure
-
-### Baseball Plugin Opportunity
-
-The baseball plugin has **over 100 properties**! With nested schemas, these could be organized into:
-- **MLB Settings**
-  - Display Modes
-  - Game Limits
-  - Display Options
-  - Background Service
-- **MiLB Settings**
-  - (same structure)
-- **NCAA Baseball Settings**
-  - (same structure)
-
-## Migration Guide
-
-### For New Plugins
-Use nested schemas from the start:
-
-```json
-{
-  "type": "object",
-  "properties": {
-    "enabled": {"type": "boolean", "default": true},
-    "sport_name": {
-      "type": "object",
-      "title": "Sport Name Settings",
-      "properties": {
-        "enabled": {"type": "boolean", "default": true},
-        "favorite_teams": {"type": "array", "items": {"type": "string"}, "default": []}
-      }
-    }
-  }
-}
-```
-
-### For Existing Plugins
-
-You have three options:
-
-1. **Keep flat** - No changes needed, works perfectly
-2. **Gradual migration** - Nest some sections, keep others flat
-3. **Full migration** - Restructure entire schema (requires updating plugin code to access nested config)
-
-## Testing
-
-### Backward Compatibility Verified
-- ✅ All 18 existing flat schemas work unchanged
-- ✅ Form generation works for flat schemas
-- ✅ Form submission works for flat schemas
-- ✅ Config saving/loading works for flat schemas
-
-### New Nested Schema Tested
-- ✅ Nested objects generate collapsible sections
-- ✅ Multi-level nesting works (object within object)
-- ✅ Form fields use correct dot notation
-- ✅ Form submission converts to nested JSON correctly
-- ✅ Boolean fields handled in nested structures
-- ✅ All field types work in nested sections (boolean, number, integer, array, string, enum)
-
-## Files Modified
-
-1. **`web_interface/templates/v3/partials/plugins.html`**
-   - Added helper functions for nested schema handling
-   - Updated `generateFormFromSchema()` to recursively handle nested objects
-   - Updated `handlePluginConfigSubmit()` to convert dot notation to nested JSON
-   - Added `toggleNestedSection()` for UI interaction
-   - Added CSS styles for nested sections
-
-## Files Created
-
-1. **`docs/NESTED_CONFIG_SCHEMAS.md`**
-   - Complete user and developer guide
-   - Examples and best practices
-   - Migration strategies
-   - Troubleshooting guide
-
-2. **`plugin-repos/ledmatrix-football-scoreboard/config_schema_nested_example.json`**
-   - Full working example of nested schema
-   - Demonstrates all nesting levels
-   - Shows before/after comparison
-
-## No Backend Changes Needed
-
-The existing API endpoints work perfectly:
-- `/api/v3/plugins/schema` - Returns schema (flat or nested)
-- `/api/v3/plugins/config` (GET) - Returns config (flat or nested)
-- `/api/v3/plugins/config` (POST) - Saves config (flat or nested)
-
-The backend doesn't care about structure - it just stores/retrieves JSON!
-
-## Next Steps
-
-### Immediate Use
-You can start using nested schemas right now:
-1. Create a new plugin with nested schema
-2. Or update an existing plugin's `config_schema.json` to use nesting
-3. The web interface will automatically render collapsible sections
-
-### Recommended Migrations
-Good candidates for nested schemas:
-- **Baseball plugin** (100+ properties → 3-4 main sections)
-- **Football plugin** (32 properties → 2 main sections) [example already created]
-- **Basketball plugin** (similar to football)
-- **Hockey plugin** (similar to football)
-
-### Future Enhancements
-Potential improvements (not required):
-- Remember collapsed/expanded state per user
-- Search within nested sections
-- Visual indication of which section has changes
-- Drag-and-drop to reorder sections
-
-## Conclusion
-
-The plugin manager now has full support for nested config schemas with:
-- ✅ Automatic UI generation
-- ✅ Collapsible sections
-- ✅ Full backward compatibility
-- ✅ No breaking changes
-- ✅ Complete documentation
-- ✅ Working examples
-
-Complex plugins can now be much easier to configure and maintain!

-# Next Steps - Run These Commands on Your Pi
-
-## What's Happening Now
-
-✅ Service is **enabled** and **active (running)**  
-⏳ Currently **installing dependencies** (this is normal on first start)  
-⏳ Should start Flask app once dependencies are installed
-
-## Commands to Run Next
-
-### 1. Wait a Minute for Dependencies to Install
-The pip install process needs to complete first.
-
-### 2. Check Current Status
-```bash
-sudo systemctl status ledmatrix-web
-```
-
-Look for the Tasks count - when it drops from 2 to 1, pip is done.
-
-### 3. View the Logs to See What's Happening
-```bash
-sudo journalctl -u ledmatrix-web -f
-```
-
-Press `Ctrl+C` to exit when done watching.
-
-You should eventually see:
-- "Dependencies installed successfully"
-- "Installing rgbmatrix module..."
-- "Launching web interface v3: ..."
-- Messages from Flask about starting the server
-
-### 4. Check if Flask is Running on Port 5000
-```bash
-sudo netstat -tlnp | grep :5000
-```
-or
-```bash
-sudo ss -tlnp | grep :5000
-```
-
-Should show Python listening on port 5000.
-
-### 5. Test Access
-Once the logs show Flask started, try accessing:
-```bash
-curl http://localhost:5000
-```
-
-Or from your computer's browser:
-```
-http://<raspberry-pi-ip>:5000
-```
-
-## If It Gets Stuck
-
-If after 2-3 minutes the dependencies are still installing and nothing happens:
-
-```bash
-# Stop the service
-sudo systemctl stop ledmatrix-web
-
-# Check what went wrong
-sudo journalctl -u ledmatrix-web -n 100 --no-pager

-# On-Demand Cache Management
-
-## Overview
-
-The on-demand feature uses several cache keys to manage state. Understanding these keys helps with troubleshooting and manual recovery.
-
-## Cache Keys Used
-
-### 1. `display_on_demand_request`
-**Purpose**: Stores pending on-demand requests (start/stop actions)  
-**TTL**: 1 hour  
-**When Set**: When you click "Run On-Demand" or "Stop On-Demand"  
-**When Cleared**: Automatically after processing, or manually via cache management
-
-**Structure**:
-```json
-{
-  "request_id": "uuid-string",
-  "action": "start" | "stop",
-  "plugin_id": "plugin-name",
-  "mode": "mode-name",
-  "duration": 30.0,
-  "pinned": true,
-  "timestamp": 1234567890.123
-}
-```
-
-### 2. `display_on_demand_config`
-**Purpose**: Stores the active on-demand configuration (persists across restarts)  
-**TTL**: 1 hour  
-**When Set**: When on-demand mode is activated  
-**When Cleared**: When on-demand mode is stopped, or manually via cache management
-
-**Structure**:
-```json
-{
-  "plugin_id": "plugin-name",
-  "mode": "mode-name",
-  "duration": 30.0,
-  "pinned": true,
-  "requested_at": 1234567890.123,
-  "expires_at": 1234567920.123
-}
-```
-
-### 3. `display_on_demand_state`
-**Purpose**: Current on-demand state (read-only, published by display controller)  
-**TTL**: None (updated continuously)  
-**When Set**: Continuously updated by display controller  
-**When Cleared**: Automatically when on-demand ends, or manually via cache management
-
-**Structure**:
-```json
-{
-  "active": true,
-  "mode": "mode-name",
-  "plugin_id": "plugin-name",
-  "requested_at": 1234567890.123,
-  "expires_at": 1234567920.123,
-  "duration": 30.0,
-  "pinned": true,
-  "status": "active" | "idle" | "restarting" | "error",
-  "error": null,
-  "last_event": "started",
-  "remaining": 25.5,
-  "last_updated": 1234567895.123
-}
-```
-
-### 4. `display_on_demand_processed_id`
-**Purpose**: Tracks which request_id has been processed (prevents duplicate processing)  
-**TTL**: 1 hour  
-**When Set**: When a request is processed  
-**When Cleared**: Automatically expires, or manually via cache management
-
-**Structure**: Just a string (the request_id)
-
-## When Manual Clearing is Needed
-
-### Scenario 1: Stuck On-Demand State
-**Symptoms**: 
-- Display stuck showing only one plugin
-- "Stop On-Demand" button doesn't work
-- Display controller shows on-demand as active but it shouldn't be
-
-**Solution**: Clear these keys:
-- `display_on_demand_config` - Removes the active configuration
-- `display_on_demand_state` - Resets the published state
-- `display_on_demand_request` - Clears any pending requests
-
-**How to Clear**: Use the Cache Management tab in the web UI:
-1. Go to Cache Management tab
-2. Find the keys starting with `display_on_demand_`
-3. Click "Delete" for each one
-4. Restart the display service: `sudo systemctl restart ledmatrix`
-
-### Scenario 2: On-Demand Mode Switching Issues
-**Symptoms**:
-- On-demand mode not switching to requested plugin
-- Logs show "Processing on-demand start request for plugin" but no "Activated on-demand for plugin" message
-- Display stuck in previous mode instead of switching immediately
-
-**Solution**: Clear these keys:
-- `display_on_demand_request` - Stops any pending request
-- `display_on_demand_processed_id` - Allows new requests to be processed
-- `display_on_demand_state` - Clears any stale state
-
-**How to Clear**: Same as Scenario 1, but focus on `display_on_demand_request` first. Note that on-demand now switches modes immediately without restarting the service.
-
-### Scenario 3: On-Demand Not Activating
-**Symptoms**:
-- Clicking "Run On-Demand" does nothing
-- No errors in logs, but on-demand doesn't start
-
-**Solution**: Clear these keys:
-- `display_on_demand_processed_id` - May be blocking new requests
-- `display_on_demand_request` - Clear any stale requests
-
-**How to Clear**: Same as Scenario 1
-
-### Scenario 4: After Service Crash or Unexpected Shutdown
-**Symptoms**:
-- Service was stopped unexpectedly (power loss, crash, etc.)
-- On-demand state may be inconsistent
-
-**Solution**: Clear all on-demand keys:
-- `display_on_demand_config`
-- `display_on_demand_state`
-- `display_on_demand_request`
-- `display_on_demand_processed_id`
-
-**How to Clear**: Same as Scenario 1, clear all four keys
-
-## Does Clearing from Cache Management Tab Reset It?
-
-**Yes, but with caveats:**
-
-1. **Clearing `display_on_demand_state`**: 
-   - ✅ Removes the published state from cache
-   - ⚠️ **Does NOT** immediately clear the in-memory state in the running display controller
-   - The display controller will continue using its internal state until it polls for updates or restarts
-
-2. **Clearing `display_on_demand_config`**:
-   - ✅ Removes the configuration from cache
-   - ⚠️ **Does NOT** immediately affect a running display controller
-   - The display controller only reads this on startup/restart
-
-3. **Clearing `display_on_demand_request`**:
-   - ✅ Prevents new requests from being processed
-   - ✅ Stops restart loops if that's the issue
-   - ⚠️ **Does NOT** stop an already-active on-demand session
-
-4. **Clearing `display_on_demand_processed_id`**:
-   - ✅ Allows previously-processed requests to be processed again
-   - Useful if a request got stuck
-
-## Best Practice for Manual Clearing
-
-**To fully reset on-demand state:**
-
-1. **Stop the display service** (if possible):
-   ```bash
-   sudo systemctl stop ledmatrix
-   ```
-
-2. **Clear all on-demand cache keys** via Cache Management tab:
-   - `display_on_demand_config`
-   - `display_on_demand_state`
-   - `display_on_demand_request`
-   - `display_on_demand_processed_id`
-
-3. **Clear systemd environment variable** (if set):
-   ```bash
-   sudo systemctl unset-environment LEDMATRIX_ON_DEMAND_PLUGIN
-   ```
-
-4. **Restart the display service**:
-   ```bash
-   sudo systemctl start ledmatrix
-   ```
-
-## Automatic Cleanup
-
-The display controller automatically:
-- Clears `display_on_demand_config` when on-demand mode is stopped
-- Updates `display_on_demand_state` continuously
-- Expires `display_on_demand_request` after processing
-- Expires `display_on_demand_processed_id` after 1 hour
-
-## Troubleshooting
-
-If clearing cache keys doesn't resolve the issue:
-
-1. **Check logs**: `sudo journalctl -u ledmatrix -f`
-2. **Check service status**: `sudo systemctl status ledmatrix`
-3. **Check environment variables**: `sudo systemctl show ledmatrix | grep LEDMATRIX`
-4. **Check cache files directly**: `ls -la /var/cache/ledmatrix/display_on_demand_*`

-# On-Demand Display API
-
-## Overview
-
-The On-Demand Display API allows **manual control** of what's shown on the LED matrix. Unlike the automatic rotation or live priority system, on-demand display is **user-triggered** - typically from the web interface with a "Show Now" button.
-
-## Use Cases
-
-- 📺 **"Show Weather Now"** button in web UI
-- 🏒 **"Show Live Game"** button for specific sports
-- 📰 **"Show Breaking News"** button
-- 🎵 **"Show Currently Playing"** button for music
-- 🎮 **Quick preview** of any plugin without waiting for rotation
-
-## Priority Hierarchy
-
-The display controller processes requests in this order:
-
-```
-1. On-Demand Display (HIGHEST) ← User explicitly requested
-2. Live Priority (plugins with live content)
-3. Normal Rotation (automatic cycling)
-```
-
-On-demand overrides everything, including live priority.
-
-## API Reference
-
-### DisplayController Methods
-
-#### `show_on_demand(mode, duration=None, pinned=False) -> bool`
-
-Display a specific mode immediately, interrupting normal rotation.
-
-**Parameters:**
-- `mode` (str): The display mode to show (e.g., 'weather', 'hockey_live')
-- `duration` (float, optional): How long to show in seconds
-  - `None`: Use mode's default `display_duration` from config
-  - `0`: Show indefinitely (until cleared)
-  - `> 0`: Show for exactly this many seconds
-- `pinned` (bool): If True, stays on this mode until manually cleared
-
-**Returns:**
-- `True`: Mode was found and activated
-- `False`: Mode doesn't exist
-
-**Example:**
-```python
-# Show weather for 30 seconds then return to rotation
-controller.show_on_demand('weather', duration=30)
-
-# Show weather indefinitely
-controller.show_on_demand('weather', duration=0)
-
-# Pin to hockey live (stays until unpinned)
-controller.show_on_demand('hockey_live', pinned=True)
-
-# Use plugin's default duration
-controller.show_on_demand('weather')  # Uses display_duration from config
-```
-
-#### `clear_on_demand() -> None`
-
-Clear on-demand display and return to normal rotation.
-
-**Example:**
-```python
-controller.clear_on_demand()
-```
-
-#### `is_on_demand_active() -> bool`
-
-Check if on-demand display is currently active.
-
-**Returns:**
-- `True`: On-demand mode is active
-- `False`: Normal rotation or live priority
-
-**Example:**
-```python
-if controller.is_on_demand_active():
-    print("User is viewing on-demand content")
-```
-
-#### `get_on_demand_info() -> dict`
-
-Get detailed information about current on-demand display.
-
-**Returns:**
-```python
-{
-    'active': True,              # Whether on-demand is active
-    'mode': 'weather',           # Current mode being displayed
-    'duration': 30.0,            # Total duration (None if indefinite)
-    'elapsed': 12.5,             # Seconds elapsed
-    'remaining': 17.5,           # Seconds remaining (None if indefinite)
-    'pinned': False              # Whether pinned
-}
-
-# Or if not active:
-{
-    'active': False
-}
-```
-
-**Example:**
-```python
-info = controller.get_on_demand_info()
-if info['active']:
-    print(f"Showing {info['mode']}, {info['remaining']}s remaining")
-```
-
-## Web Interface Integration
-
-### API Endpoint Example
-
-```python
-# In web_interface/blueprints/api_v3.py
-
-from flask import jsonify, request
-
-@api_v3.route('/display/show', methods=['POST'])
-def show_on_demand():
-    """Show a specific plugin on-demand"""
-    data = request.json
-    mode = data.get('mode')
-    duration = data.get('duration')  # Optional
-    pinned = data.get('pinned', False)  # Optional
-    
-    # Get display controller instance
-    controller = get_display_controller()
-    
-    success = controller.show_on_demand(mode, duration, pinned)
-    
-    if success:
-        return jsonify({
-            'success': True,
-            'message': f'Showing {mode}',
-            'info': controller.get_on_demand_info()
-        })
-    else:
-        return jsonify({
-            'success': False,
-            'error': f'Mode {mode} not found'
-        }), 404
-
-@api_v3.route('/display/clear', methods=['POST'])
-def clear_on_demand():
-    """Clear on-demand display"""
-    controller = get_display_controller()
-    controller.clear_on_demand()
-    
-    return jsonify({
-        'success': True,
-        'message': 'On-demand display cleared'
-    })
-
-@api_v3.route('/display/on-demand-info', methods=['GET'])
-def get_on_demand_info():
-    """Get on-demand display status"""
-    controller = get_display_controller()
-    info = controller.get_on_demand_info()
-    
-    return jsonify(info)
-```
-
-### Frontend Example (JavaScript)

-```javascript
-// Show weather for 30 seconds
-async function showWeather() {
-    const response = await fetch('/api/v3/display/show', {
-        method: 'POST',

-    } else {
-        updateStatus('Normal rotation');
-    }
-}
-```
-
-### UI Example (HTML)
-
-```html
-<!-- Plugin controls -->
-<div class="plugin-card">
-    <h3>Weather</h3>
-    <button onclick="showWeather()">Show Now (30s)</button>
-    <button onclick="showWeatherIndefinite()">Show Until Cleared</button>
-    <button onclick="pinWeather()">Pin Weather</button>
-</div>
-
-<!-- On-demand status display -->
-<div id="on-demand-status" class="status-bar">
-    <span id="status-text">Normal rotation</span>
-    <button id="clear-btn" onclick="clearOnDemand()" style="display: none;">
-        Clear On-Demand
-    </button>
-</div>
-
-<script>
-// Poll for status updates
-setInterval(async () => {
-    const info = await fetch('/api/v3/display/on-demand-info').then(r => r.json());
-    
-    const statusText = document.getElementById('status-text');
-    const clearBtn = document.getElementById('clear-btn');
-    
-    if (info.active) {
-        let text = `On-demand: ${info.mode}`;
-        if (info.remaining) {
-            text += ` (${Math.ceil(info.remaining)}s)`;
-        } else if (info.pinned) {
-            text += ' (pinned)';
-        }
-        statusText.textContent = text;
-        clearBtn.style.display = 'inline-block';
-    } else {
-        statusText.textContent = 'Normal rotation';
-        clearBtn.style.display = 'none';
-    }
-}, 1000);  // Update every second
-</script>
-```
-
-## Behavior Details
-
-### Duration Modes
-
-| Duration Value | Behavior | Use Case |
-|---------------|----------|----------|
-| `None` | Use plugin's `display_duration` from config | Default behavior |
-| `0` | Show indefinitely until cleared | Quick preview |
-| `> 0` | Show for exactly N seconds | Timed preview |
-| `pinned=True` | Stay on mode until unpinned | Extended viewing |
-
-### Auto-Clear Behavior
-
-On-demand display automatically clears when:
-- Duration expires (if set and > 0)
-- User manually clears it
-- System restarts
-
-On-demand does NOT clear when:
-- `duration=0` (indefinite)
-- `pinned=True`
-- Live priority content appears (on-demand still has priority)
-
-### Interaction with Live Priority
-
-```python
-# Scenario 1: On-demand overrides live priority
-controller.show_on_demand('weather', duration=30)
-# → Shows weather even if live game is happening
-
-# Scenario 2: After on-demand expires, live priority takes over
-controller.show_on_demand('weather', duration=10)
-# → Shows weather for 10s
-# → If live game exists, switches to live game
-# → Otherwise returns to normal rotation
-```
-
-## Use Case Examples
-
-### Example 1: Quick Weather Check
-
-```python
-# User clicks "Show Weather" button
-controller.show_on_demand('weather', duration=30)
-# Shows weather for 30 seconds, then returns to rotation
-```
-
-### Example 2: Monitor Live Game
-
-```python
-# User clicks "Watch Live Game" button
-controller.show_on_demand('hockey_live', pinned=True)
-# Stays on live game until user clicks "Back to Rotation"
-```
-
-### Example 3: Preview Plugin
-
-```python
-# User clicks "Preview" in plugin settings
-controller.show_on_demand('my-plugin', duration=15)
-# Shows plugin for 15 seconds to test configuration
-```
-
-### Example 4: Emergency Override
-
-```python
-# Admin needs to show important message
-controller.show_on_demand('text-display', pinned=True)
-# Display stays on message until admin clears it
-```
-
-## Testing
-
-### Manual Test from Python
-
-```python
-# Access display controller
-from src.display_controller import DisplayController
-controller = DisplayController()  # Or get existing instance
-
-# Test show on-demand
-controller.show_on_demand('weather', duration=20)
-print(controller.get_on_demand_info())
-
-# Test clear
-time.sleep(5)
-controller.clear_on_demand()
-print(controller.get_on_demand_info())
-```
-
-### Test with Web API
-
-```bash
-# Show weather for 30 seconds
-curl -X POST http://pi-ip:5001/api/v3/display/show \
-  -H "Content-Type: application/json" \
-  -d '{"mode": "weather", "duration": 30}'
-
-# Check status
-curl http://pi-ip:5001/api/v3/display/on-demand-info
-
-# Clear on-demand
-curl -X POST http://pi-ip:5001/api/v3/display/clear
-```
-
-### Monitor Logs
-
-```bash
-sudo journalctl -u ledmatrix -f | grep -i "on-demand"
-```
-
-Expected output:
-```
-On-demand display activated: weather (duration: 30s, pinned: False)
-On-demand display expired after 30.1s
-Clearing on-demand display: weather
-```
-
-## Best Practices
-
-### 1. Provide Visual Feedback
-
-Always show users when on-demand is active:
-
-```javascript
-// Update UI to show on-demand status
-function updateOnDemandUI(info) {
-    const banner = document.getElementById('on-demand-banner');
-    if (info.active) {
-        banner.style.display = 'block';
-        banner.textContent = `Showing: ${info.mode}`;
-        if (info.remaining) {
-            banner.textContent += ` (${Math.ceil(info.remaining)}s)`;
-        }
-    } else {
-        banner.style.display = 'none';
-    }
-}
-```
-
-### 2. Default to Timed Display
-
-Unless explicitly requested, use a duration:
-
-```python
-# Good: Auto-clears after 30 seconds
-controller.show_on_demand('weather', duration=30)
-
-# Risky: Stays indefinitely
-controller.show_on_demand('weather', duration=0)
-```
-
-### 3. Validate Modes
-
-Check if mode exists before showing:
-
-```python
-# Get available modes
-available_modes = controller.available_modes + list(controller.plugin_modes.keys())
-
-if mode in available_modes:
-    controller.show_on_demand(mode, duration=30)
-else:
-    return jsonify({'error': 'Mode not found'}), 404
-```
-
-### 4. Handle Concurrent Requests
-
-Last request wins:
-
-```python
-# Request 1: Show weather
-controller.show_on_demand('weather', duration=30)
-
-# Request 2: Show hockey (overrides weather)
-controller.show_on_demand('hockey_live', duration=20)
-# Hockey now shows for 20s, weather request is forgotten
-```
-
-## Troubleshooting
-
-### On-Demand Not Working
-
-**Check 1:** Verify mode exists
-```python
-info = controller.get_on_demand_info()
-print(f"Active: {info['active']}, Mode: {info.get('mode')}")
-print(f"Available modes: {controller.available_modes}")
-```
-
-**Check 2:** Check logs
-```bash
-sudo journalctl -u ledmatrix -f | grep "on-demand\|available modes"
-```
-
-### On-Demand Not Clearing
-
-**Check if pinned:**
-```python
-info = controller.get_on_demand_info()
-if info['pinned']:
-    print("Mode is pinned - must clear manually")
-    controller.clear_on_demand()
-```
-
-**Check duration:**
-```python
-if info['duration'] == 0:
-    print("Duration is indefinite - must clear manually")
-```
-
-### Mode Shows But Looks Wrong
-
-This is a **display** issue, not an on-demand issue. Check:
-- Plugin's `update()` method is fetching data
-- Plugin's `display()` method is rendering correctly
-- Cache is not stale
-
-## Security Considerations
-
-### 1. Authentication Required
-
-Always require authentication for on-demand control:
-
-```python
-@api_v3.route('/display/show', methods=['POST'])
-@login_required  # Add authentication
-def show_on_demand():
-    # ... implementation
-```
-
-### 2. Rate Limiting
-
-Prevent spam:
-
-```python
-from flask_limiter import Limiter
-
-limiter = Limiter(app, key_func=get_remote_address)
-
-@api_v3.route('/display/show', methods=['POST'])
-@limiter.limit("10 per minute")  # Max 10 requests per minute
-def show_on_demand():
-    # ... implementation
-```
-
-### 3. Input Validation
-
-Sanitize mode names:
-
-```python
-import re
-
-def validate_mode(mode):
-    # Only allow alphanumeric, underscore, hyphen
-    if not re.match(r'^[a-zA-Z0-9_-]+$', mode):
-        raise ValueError("Invalid mode name")
-    return mode
-```
-

-# On-Demand Display - Quick Start Guide
-
-## 🎯 What Is It?
-
-On-Demand Display lets users **manually trigger** specific plugins to show on the LED matrix - perfect for "Show Now" buttons in your web interface!
-
-> **2025 update:** The LEDMatrix web interface now ships with first-class on-demand controls. You can trigger plugins directly from the Plugin Management page or by calling the new `/api/v3/display/on-demand/*` endpoints described below. The legacy quick-start steps are still documented for bespoke integrations.
-
-## ✅ Built-In Controls
-
-### Web Interface (no-code)
-
-- Navigate to **Settings → Plugin Management**.
-- Each installed plugin now exposes a **Run On-Demand** button:
-  - Choose the display mode (when a plugin exposes multiple views).
-  - Optionally set a fixed duration (leave blank to use the plugin default or `0` to run until you stop it).
-  - Pin the plugin so rotation stays paused.
-  - The dashboard shows real-time status and lets you stop the session. **Shift+click** the stop button to stop the display service after clearing the plugin.
-- The status card refreshes automatically and indicates whether the display service is running.
-
-### REST Endpoints
-
-All endpoints live under `/api/v3/display/on-demand`.
-
-| Endpoint | Method | Description |
-|----------|--------|-------------|
-| `/status` | GET | Returns the current on-demand state plus display service health. |
-| `/start`  | POST | Requests a plugin/mode to run. Automatically starts the display service (unless `start_service: false`). |
-| `/stop`   | POST | Clears on-demand mode. Include `{"stop_service": true}` to stop the systemd service. |
-
-Example `curl` calls:
-
-```bash
-# Start the default mode for football-scoreboard for 45 seconds
-curl -X POST http://localhost:5000/api/v3/display/on-demand/start \
-     -H "Content-Type: application/json" \
-     -d '{
-            "plugin_id": "football-scoreboard",
-            "duration": 45,
-            "pinned": true
-         }'
-
-# Start by mode name (plugin id inferred automatically)
-curl -X POST http://localhost:5000/api/v3/display/on-demand/start \
-     -H "Content-Type: application/json" \
-     -d '{ "mode": "football_live" }'
-
-# Stop on-demand and shut down the display service
-curl -X POST http://localhost:5000/api/v3/display/on-demand/stop \
-     -H "Content-Type: application/json" \
-     -d '{ "stop_service": true }'
-
-# Check current status
-curl http://localhost:5000/api/v3/display/on-demand/status | jq
-```
-
-**Notes**
-
-- The display controller will honour the plugin’s configured `display_duration` when no duration is provided.
-- When you pass `duration: 0` (or omit it) and `pinned: true`, the plugin stays active until you issue `/stop`.
-- The service automatically resumes normal rotation after the on-demand session expires or is cleared.
-
-## 🚀 Quick Implementation (3 Steps)
-
-> The steps below describe a lightweight custom implementation that predates the built-in API. You generally no longer need this unless you are integrating with a separate control surface.
-
-### Step 1: Add API Endpoint
-
-```python
-# In web_interface/blueprints/api_v3.py
-
-@api_v3.route('/display/show', methods=['POST'])
-def show_on_demand():
-    data = request.json
-    mode = data.get('mode')
-    duration = data.get('duration', 30)  # Default 30 seconds
-    
-    # Get display controller (implementation depends on your setup)
-    controller = get_display_controller()
-    
-    success = controller.show_on_demand(mode, duration=duration)
-    
-    return jsonify({'success': success})
-
-@api_v3.route('/display/clear', methods=['POST'])
-def clear_on_demand():
-    controller = get_display_controller()
-    controller.clear_on_demand()
-    return jsonify({'success': True})
-```
-
-### Step 2: Add UI Button
-
-```html
-<!-- Show weather button -->
-<button onclick="showWeather()">Show Weather Now</button>
-
-<script>
-async function showWeather() {
-    await fetch('/api/v3/display/show', {
-        method: 'POST',
-        headers: { 'Content-Type': 'application/json' },
-        body: JSON.stringify({
-            mode: 'weather',
-            duration: 30  // Show for 30 seconds
-        })
-    });
-}
-</script>
-```
-
-### Step 3: Done! 🎉
-
-Users can now click the button to show weather immediately!

-
-## ⚡ Usage Patterns
-
-### Pattern 1: Timed Preview
-```javascript
-// Show for 30 seconds then return to rotation
-showPlugin('weather', 30);
-```
-
-### Pattern 2: Pinned Display
-```javascript
-// Stay on this plugin until manually cleared
-pinPlugin('hockey_live');
-```
-
-### Pattern 3: Quick Check
-```javascript
-// Show for 10 seconds
-showPlugin('clock', 10);
-```
-
-### Pattern 4: Indefinite Display
-```javascript
-// Show until cleared (duration=0)
-fetch('/api/v3/display/show', {
-    method: 'POST',
-    body: JSON.stringify({ mode: 'weather', duration: 0 })
-});
-```
-
-## 📊 Priority Order
-
-```
-User clicks "Show Weather" button
-         ↓
-1. On-Demand (Highest) ← Shows immediately
-2. Live Priority        ← Overridden
-3. Normal Rotation      ← Paused
-```
-
-On-demand has **highest priority** - it overrides everything!
-
-## 🎮 Common Use Cases
-
-### Quick Weather Check
-```html
-<button onclick="showPlugin('weather', 20)">
-    Check Weather
-</button>
-```

-
-## ❓ FAQ
-
-### Q: What happens when duration expires?
-**A:** Display automatically returns to normal rotation (or live priority if active).
-
-### Q: Can I show multiple modes at once?
-**A:** No, only one mode at a time. Last request wins.
-
-### Q: Does it override live games?
-**A:** Yes! On-demand has highest priority, even over live priority.
-
-### Q: How do I go back to normal rotation?
-**A:** Either wait for duration to expire, or call `clearOnDemand()`.
-
-### Q: What if the mode doesn't exist?
-**A:** API returns `success: false` and logs a warning.
-
-## 🐛 Testing
-
-### Test 1: Show for 30 seconds
-```bash
-curl -X POST http://pi-ip:5001/api/v3/display/show \

-# Optimal WiFi Configuration with Failover AP Mode
-
-## Overview
-
-This guide explains the optimal way to configure WiFi with automatic failover to Access Point (AP) mode, ensuring you can always connect to your Raspberry Pi even when the primary WiFi network is unavailable.
-
-## System Architecture
-
-### How It Works
-
-The LEDMatrix WiFi system uses a **grace period mechanism** to prevent false positives from transient network hiccups:
-
-1. **WiFi Monitor Daemon** runs as a background service (every 30 seconds by default)
-2. **Grace Period**: Requires **3 consecutive disconnected checks** before enabling AP mode
-   - At 30-second intervals, this means **90 seconds** of confirmed disconnection
-   - This prevents AP mode from activating during brief network interruptions
-3. **Automatic Failover**: When both WiFi and Ethernet are disconnected for the grace period, AP mode activates
-4. **Automatic Recovery**: When WiFi or Ethernet reconnects, AP mode automatically disables
-
-### Connection Priority
-
-The system checks connections in this order:
-1. **WiFi Connection** (highest priority)
-2. **Ethernet Connection** (fallback)
-3. **AP Mode** (last resort - only when both WiFi and Ethernet are disconnected)
-
-## Optimal Configuration
-
-### Recommended Settings
-
-For a **reliable failover system**, use these settings:
-
-```json
-{
-  "ap_ssid": "LEDMatrix-Setup",
-  "ap_password": "ledmatrix123",
-  "ap_channel": 7,
-  "auto_enable_ap_mode": true,
-  "saved_networks": [
-    {
-      "ssid": "YourPrimaryNetwork",
-      "password": "your-password"
-    }
-  ]
-}
-```
-
-### Key Configuration Options
-
-| Setting | Recommended Value | Purpose |
-|---------|------------------|---------|
-| `auto_enable_ap_mode` | `true` | Enables automatic failover to AP mode |
-| `ap_ssid` | `LEDMatrix-Setup` | Network name for AP mode (customizable) |
-| `ap_password` | `ledmatrix123` | Password for AP mode (change for security) |
-| `ap_channel` | `7` (or 1, 6, 11) | WiFi channel (use non-overlapping channels) |
-| `saved_networks` | Array of networks | Pre-configured networks for quick connection |
-
-## Step-by-Step Setup
-
-### 1. Initial Configuration
-
-**Via Web Interface (Recommended):**
-
-1. Connect to your Raspberry Pi (via Ethernet or existing WiFi)
-2. Navigate to the **WiFi** tab in the web interface
-3. Configure your primary WiFi network:
-   - Click **Scan** to find networks
-   - Select your network from the dropdown
-   - Enter your WiFi password
-   - Click **Connect**
-4. Enable auto-failover:
-   - Toggle **"Auto-Enable AP Mode"** to **ON**
-   - This enables automatic failover when WiFi disconnects
-
-**Via Configuration File:**
-
-```bash
-# Edit the WiFi configuration
-nano config/wifi_config.json
-```
-
-Set `auto_enable_ap_mode` to `true`:
-
-```json
-{
-  "auto_enable_ap_mode": true,
-  ...
-}
-```
-
-### 2. Verify WiFi Monitor Service
-
-The WiFi monitor daemon must be running for automatic failover:
-
-```bash
-# Check service status
-sudo systemctl status ledmatrix-wifi-monitor
-
-# If not running, start it
-sudo systemctl start ledmatrix-wifi-monitor
-
-# Enable on boot
-sudo systemctl enable ledmatrix-wifi-monitor
-```
-
-### 3. Test Failover Behavior
-
-**Test Scenario 1: WiFi Disconnection**
-
-1. Disconnect your WiFi router or move the Pi out of range
-2. Wait **90 seconds** (3 check intervals × 30 seconds)
-3. AP mode should automatically activate
-4. Connect to **LEDMatrix-Setup** network from your device
-5. Access web interface at `http://192.168.4.1:5000`
-
-**Test Scenario 2: WiFi Reconnection**
-
-1. Reconnect WiFi router or move Pi back in range
-2. Within **30 seconds**, AP mode should automatically disable
-3. Pi should reconnect to your primary WiFi network
-
-## How the Grace Period Works
-
-### Disconnected Check Counter
-
-The system uses a **disconnected check counter** to prevent false positives:
-
-```
-Check Interval: 30 seconds (configurable)
-Required Checks: 3 consecutive
-Grace Period: 90 seconds total
-```
-
-**Example Timeline:**
-
-```
-Time 0s:   WiFi disconnects
-Time 30s:  Check 1 - Disconnected (counter = 1)
-Time 60s:  Check 2 - Disconnected (counter = 2)
-Time 90s:  Check 3 - Disconnected (counter = 3) → AP MODE ENABLED
-```
-
-If WiFi reconnects at any point, the counter resets to 0.
-
-### Why Grace Period is Important
-
-Without a grace period, AP mode would activate during:
-- Brief network hiccups
-- Router reboots
-- Temporary signal interference
-- NetworkManager reconnection attempts
-
-The 90-second grace period ensures AP mode only activates when there's a **sustained disconnection**.
-
-## Best Practices
-
-### 1. Security Considerations
-
-**Change Default AP Password:**
-
-```json
-{
-  "ap_password": "your-strong-password-here"
-}
-```
-
-**Use Non-Overlapping WiFi Channels:**
-
-- Channels 1, 6, 11 are non-overlapping (2.4GHz)
-- Choose a channel that doesn't conflict with your primary network
-- Example: If primary network uses channel 1, use channel 11 for AP mode
-
-### 2. Network Configuration
-
-**Save Multiple Networks:**
-
-You can save multiple WiFi networks for automatic connection:
-
-```json
-{
-  "saved_networks": [
-    {
-      "ssid": "Home-Network",
-      "password": "home-password"
-    },
-    {
-      "ssid": "Office-Network",
-      "password": "office-password"
-    }
-  ]
-}
-```
-
-**Note:** Saved networks are stored for reference but connection still requires manual selection or NetworkManager auto-connect.
-
-### 3. Monitoring and Troubleshooting
-
-**Check Service Logs:**
-
-```bash
-# View real-time logs
-sudo journalctl -u ledmatrix-wifi-monitor -f
-
-# View recent logs
-sudo journalctl -u ledmatrix-wifi-monitor -n 50
-```
-
-**Check WiFi Status:**
-
-```bash
-# Via Python
-python3 -c "
-from src.wifi_manager import WiFiManager
-wm = WiFiManager()
-status = wm.get_wifi_status()
-print(f'Connected: {status.connected}')
-print(f'SSID: {status.ssid}')
-print(f'IP: {status.ip_address}')
-print(f'AP Mode: {status.ap_mode_active}')
-print(f'Auto-Enable: {wm.config.get(\"auto_enable_ap_mode\", False)}')
-"
-```
-
-**Check NetworkManager Status:**
-
-```bash
-# View device status
-nmcli device status
-
-# View connections
-nmcli connection show
-
-# View WiFi networks
-nmcli device wifi list
-```
-
-### 4. Customization Options
-
-**Adjust Check Interval:**
-
-Edit the systemd service file:
-
-```bash
-sudo systemctl edit ledmatrix-wifi-monitor
-```
-
-Add:
-
-```ini
-[Service]
-ExecStart=
-ExecStart=/usr/bin/python3 /path/to/LEDMatrix/scripts/utils/wifi_monitor_daemon.py --interval 20
-```
-
-Then restart:
-
-```bash
-sudo systemctl daemon-reload
-sudo systemctl restart ledmatrix-wifi-monitor
-```
-
-**Note:** Changing the interval affects the grace period:
-- 20-second interval = 60-second grace period (3 × 20)
-- 30-second interval = 90-second grace period (3 × 30) ← Default
-- 60-second interval = 180-second grace period (3 × 60)
-
-## Configuration Scenarios
-
-### Scenario 1: Always-On Failover (Recommended)
-
-**Use Case:** Portable device that may lose WiFi connection
-
-**Configuration:**
-```json
-{
-  "auto_enable_ap_mode": true
-}
-```
-
-**Behavior:**
-- AP mode activates automatically after 90 seconds of disconnection
-- Always provides a way to connect to the device
-- Best for devices that move or have unreliable WiFi
-
-### Scenario 2: Manual AP Mode Only
-
-**Use Case:** Stable network connection (e.g., Ethernet or reliable WiFi)
-
-**Configuration:**
-```json
-{
-  "auto_enable_ap_mode": false
-}
-```
-
-**Behavior:**
-- AP mode must be manually enabled via web UI
-- Prevents unnecessary AP mode activation
-- Best for stationary devices with stable connections
-
-### Scenario 3: Ethernet Primary with WiFi Failover
-
-**Use Case:** Device primarily uses Ethernet, WiFi as backup
-
-**Configuration:**
-```json
-{
-  "auto_enable_ap_mode": true
-}
-```
-
-**Behavior:**
-- Ethernet connection prevents AP mode activation
-- If Ethernet disconnects, WiFi is attempted
-- If both disconnect, AP mode activates after grace period
-- Best for devices with both Ethernet and WiFi
-
-## Troubleshooting
-
-### AP Mode Not Activating
-
-**Check 1: Auto-Enable Setting**
-```bash
-cat config/wifi_config.json | grep auto_enable_ap_mode
-```
-Should show `"auto_enable_ap_mode": true`
-
-**Check 2: Service Status**
-```bash
-sudo systemctl status ledmatrix-wifi-monitor
-```
-Service should be `active (running)`
-
-**Check 3: Grace Period**
-- Wait at least 90 seconds after disconnection
-- Check logs: `sudo journalctl -u ledmatrix-wifi-monitor -f`
-
-**Check 4: Ethernet Connection**
-- If Ethernet is connected, AP mode won't activate
-- Disconnect Ethernet to test AP mode
-
-### AP Mode Activating Unexpectedly
-
-**Check 1: Network Stability**
-- Verify WiFi connection is stable
-- Check for router issues or signal problems
-
-**Check 2: Grace Period Too Short**
-- Current grace period is 90 seconds
-- Brief disconnections shouldn't trigger AP mode
-- Check logs for disconnection patterns
-
-**Check 3: Disable Auto-Enable**
-```bash
-# Set to false
-nano config/wifi_config.json
-# Change: "auto_enable_ap_mode": false
-sudo systemctl restart ledmatrix-wifi-monitor
-```
-
-### Cannot Connect to AP Mode
-
-**Check 1: AP Mode Active**
-```bash
-sudo systemctl status hostapd
-sudo systemctl status dnsmasq
-```
-
-**Check 2: Network Interface**
-```bash
-ip addr show wlan0
-```
-Should show IP `192.168.4.1`
-
-**Check 3: Firewall**
-```bash
-sudo iptables -L -n
-```
-Check if port 5000 is accessible
-
-**Check 4: Manual Enable**
-- Try manually enabling AP mode via web UI
-- Or via API: `curl -X POST http://localhost:5001/api/v3/wifi/ap/enable`
-
-## Summary
-
-### Optimal Configuration Checklist
-
-- [ ] `auto_enable_ap_mode` set to `true`
-- [ ] WiFi monitor service running and enabled
-- [ ] Primary WiFi network configured and tested
-- [ ] AP password changed from default
-- [ ] AP channel configured (non-overlapping)
-- [ ] Grace period understood (90 seconds)
-- [ ] Failover behavior tested
-
-### Key Takeaways
-
-1. **Grace Period**: 90 seconds prevents false positives
-2. **Auto-Enable**: Set to `true` for reliable failover
-3. **Service**: WiFi monitor daemon must be running
-4. **Priority**: WiFi → Ethernet → AP Mode
-5. **Automatic**: AP mode disables when WiFi/Ethernet connects
-
-This configuration provides a robust failover system that ensures you can always access your Raspberry Pi, even when the primary network connection fails.

-# Permission Management Guide
-
-## Overview
-
-LEDMatrix runs with a dual-user architecture: the main display service runs as `root` (for hardware access), while the web interface runs as a regular user. This guide explains how to properly manage file and directory permissions to ensure both services can access the files they need.
-

-1. [Why Permission Management Matters](#why-permission-management-matters)
-2. [Permission Utilities](#permission-utilities)
-3. [When to Use Permission Utilities](#when-to-use-permission-utilities)
-4. [How to Use Permission Utilities](#how-to-use-permission-utilities)
-5. [Common Patterns and Examples](#common-patterns-and-examples)
-6. [Permission Standards](#permission-standards)
-7. [Troubleshooting](#troubleshooting)
-
----
-
-## Why Permission Management Matters
-
-### The Problem
-
-Without proper permission management, you may encounter errors like:
-- `PermissionError: [Errno 13] Permission denied` when saving config files
-- `PermissionError` when downloading team logos
-- Files created by the root service not accessible by the web user
-- Files created by the web user not accessible by the root service
-
-### The Solution
-
-The LEDMatrix codebase includes centralized permission utilities (`src/common/permission_utils.py`) that ensure files and directories are created with appropriate permissions for both users.
-
----
-
-## Permission Utilities
-
-### Available Functions
-
-The permission utilities module provides the following functions:
-
-#### Directory Management
-
-- `ensure_directory_permissions(path: Path, mode: int = 0o775) -> None`
-  - Creates directory if it doesn't exist
-  - Sets permissions to the specified mode
-  - Default mode: `0o775` (rwxrwxr-x) - group-writable
-
-#### File Management
-
-- `ensure_file_permissions(path: Path, mode: int = 0o644) -> None`
-  - Sets permissions on an existing file
-  - Default mode: `0o644` (rw-r--r--) - world-readable
-
-#### Mode Helpers
-
-These functions return the appropriate permission mode for different file types:
-
-- `get_config_file_mode(file_path: Path) -> int`
-  - Returns `0o640` for secrets files, `0o644` for regular config files
-
-- `get_assets_file_mode() -> int`
-  - Returns `0o664` (rw-rw-r--) for asset files (logos, images)
-
-- `get_assets_dir_mode() -> int`
-  - Returns `0o2775` (rwxrwsr-x) for asset directories
-  - Setgid bit enforces inherited group ownership for new files/directories
-
-- `get_config_dir_mode() -> int`
-  - Returns `0o2775` (rwxrwsr-x) for config directories
-  - Setgid bit enforces inherited group ownership for new files/directories
-
-- `get_plugin_file_mode() -> int`
-  - Returns `0o664` (rw-rw-r--) for plugin files
-
-- `get_plugin_dir_mode() -> int`
-  - Returns `0o2775` (rwxrwsr-x) for plugin directories
-  - Setgid bit enforces inherited group ownership for new files/directories
-
-- `get_cache_dir_mode() -> int`
-  - Returns `0o2775` (rwxrwsr-x) for cache directories
-  - Setgid bit enforces inherited group ownership for new files/directories
-
----
-
-## When to Use Permission Utilities
-
-### Always Use Permission Utilities When:
-
-1. **Creating directories** - Use `ensure_directory_permissions()` instead of `os.makedirs()` or `Path.mkdir()`
-2. **Saving files** - Use `ensure_file_permissions()` after writing files
-3. **Downloading assets** - Set permissions after downloading logos, images, or other assets
-4. **Creating config files** - Set permissions after saving configuration files
-5. **Creating cache files** - Set permissions when creating cache directories or files
-6. **Plugin file operations** - Set permissions when plugins create their own files/directories
-
-### You Don't Need Permission Utilities When:
-
-1. **Reading files** - Reading doesn't require permission changes
-2. **Using core utilities** - Core utilities (LogoHelper, CacheManager, ConfigManager) already handle permissions
-3. **Temporary files** - Files in `/tmp` or created with `tempfile` don't need special permissions
-
----
-
-## How to Use Permission Utilities
-

-
-## Common Patterns and Examples
-
-### Pattern 1: Config File Save
-
-```python
-from pathlib import Path
-from src.common.permission_utils import (
-    ensure_directory_permissions,
-    ensure_file_permissions,
-    get_config_dir_mode,
-    get_config_file_mode
-)
-
-def save_config(config_data: dict, config_path: str) -> None:
-    """Save configuration file with proper permissions."""
-    path = Path(config_path)
-    
-    # Ensure directory exists
-    ensure_directory_permissions(path.parent, get_config_dir_mode())
-    
-    # Write file
-    with open(path, 'w') as f:
-        json.dump(config_data, f, indent=4)
-    
-    # Set permissions
-    ensure_file_permissions(path, get_config_file_mode(path))
-```
-
-### Pattern 2: Asset Directory Setup
-
-```python
-from pathlib import Path
-from src.common.permission_utils import (
-    ensure_directory_permissions,
-    get_assets_dir_mode
-)
-
-def setup_asset_directory(base_dir: str, subdir: str) -> Path:
-    """Create asset directory with proper permissions."""
-    asset_dir = Path(base_dir) / subdir
-    ensure_directory_permissions(asset_dir, get_assets_dir_mode())
-    return asset_dir
-```
-
-### Pattern 3: Plugin File Creation
-
-```python
-from pathlib import Path
-from src.common.permission_utils import (
-    ensure_directory_permissions,
-    ensure_file_permissions,
-    get_plugin_dir_mode,
-    get_plugin_file_mode
-)
-
-def save_plugin_data(plugin_id: str, data: dict) -> None:
-    """Save plugin data file with proper permissions."""
-    plugin_dir = Path("plugins") / plugin_id
-    data_file = plugin_dir / "data.json"
-    
-    # Ensure plugin directory exists
-    ensure_directory_permissions(plugin_dir, get_plugin_dir_mode())
-    
-    # Write file
-    with open(data_file, 'w') as f:
-        json.dump(data, f, indent=2)
-    
-    # Set permissions

-```
-
-### Pattern 4: Cache Directory Creation
-
-```python
-from pathlib import Path
-from src.common.permission_utils import (
-    ensure_directory_permissions,
-    get_cache_dir_mode
-)
-
-def get_cache_directory() -> Path:
-    """Get or create cache directory with proper permissions."""
-    cache_dir = Path("/var/cache/ledmatrix")
-    ensure_directory_permissions(cache_dir, get_cache_dir_mode())
-    return cache_dir
-```
-
-### Pattern 5: Atomic File Write with Permissions
-
-```python
-from pathlib import Path
-import tempfile
-import os
-from src.common.permission_utils import (
-    ensure_directory_permissions,
-    ensure_file_permissions,
-    get_config_dir_mode,
-    get_config_file_mode
-)
-
-def save_config_atomic(config_data: dict, config_path: str) -> None:
-    """Save config file atomically with proper permissions."""
-    path = Path(config_path)
-    
-    # Ensure directory exists
-    ensure_directory_permissions(path.parent, get_config_dir_mode())
-    
-    # Write to temp file first
-    temp_path = path.with_suffix('.tmp')
-    with open(temp_path, 'w') as f:
-        json.dump(config_data, f, indent=4)
-    
-    # Set permissions on temp file
-    ensure_file_permissions(temp_path, get_config_file_mode(path))
-    
-    # Atomic move
-    temp_path.replace(path)
-    
-    # Permissions are preserved after move, but ensure they're correct
-    ensure_file_permissions(path, get_config_file_mode(path))
-```

-## Permission Standards
-
-### File Permissions
-
-| File Type | Mode | Octal | Description |
-|-----------|------|-------|-------------|
-| Config files | `rw-r--r--` | `0o644` | Readable by all, writable by owner |
-| Secrets files | `rw-r-----` | `0o640` | Readable by owner and group only |
-| Asset files | `rw-rw-r--` | `0o664` | Group-writable for root:user access |
-| Plugin files | `rw-rw-r--` | `0o664` | Group-writable for root:user access |
-
-### Directory Permissions
-
-| Directory Type | Mode | Octal | Description |
-|----------------|------|-------|-------------|
-| Config directories | `rwxrwsr-x` | `0o2775` (setgid) | Group-writable with setgid bit for inherited group ownership |
-| Asset directories | `rwxrwsr-x` | `0o2775` (setgid) | Group-writable with setgid bit for inherited group ownership |
-| Plugin directories | `rwxrwsr-x` | `0o2775` (setgid) | Group-writable with setgid bit for inherited group ownership |
-| Cache directories | `rwxrwsr-x` | `0o2775` (setgid) | Group-writable with setgid bit for inherited group ownership |
-
-### Why These Permissions?
-
-- **Group-writable (664)**: Allows both root service and web user to read/write files
-- **Directory setgid bit (2775)**: Ensures new files and directories inherit the group ownership, maintaining consistent permissions
-- **World-readable (644)**: Config files need to be readable by root service
-- **Restricted (640)**: Secrets files should only be readable by owner and group
-

-
-## Troubleshooting
-
-### Common Issues
-
-#### Issue: Permission denied when saving config
-
-**Symptoms:**
-```
-PermissionError: [Errno 13] Permission denied: 'config/config.json'
-```
-
-**Solution:**
-Ensure you're using `ensure_directory_permissions()` and `ensure_file_permissions()`:
-
-```python
-from src.common.permission_utils import (
-    ensure_directory_permissions,
-    ensure_file_permissions,
-    get_config_dir_mode,
-    get_config_file_mode
-)
-
-path = Path("config/config.json")
-ensure_directory_permissions(path.parent, get_config_dir_mode())
-# ... write file ...
-ensure_file_permissions(path, get_config_file_mode(path))
-```
-
-#### Issue: Logo downloads fail with permission errors
-
-**Symptoms:**
-```
-PermissionError: Cannot write to directory assets/sports/logos
-```
-
-**Solution:**
-Use permission utilities when creating directories and saving files:
-
-```python
-from src.common.permission_utils import (
-    ensure_directory_permissions,
-    ensure_file_permissions,
-    get_assets_dir_mode,
-    get_assets_file_mode
-)
-
-logo_path = Path("assets/sports/logos/team.png")
-ensure_directory_permissions(logo_path.parent, get_assets_dir_mode())
-# ... download and save ...
-ensure_file_permissions(logo_path, get_assets_file_mode())
-```
-
-#### Issue: Files created by root service not accessible by web user
-
-**Symptoms:**
-- Web interface can't read files created by the service
-- Files show as owned by root with restrictive permissions
-
-**Solution:**
-Always use permission utilities when creating files. The utilities set group-writable permissions (664/775) that allow both users to access files.
-
-#### Issue: Plugin can't write to its directory
-
-**Symptoms:**
-```
-PermissionError: Cannot write to plugins/my-plugin/data.json
-```
-
-**Solution:**
-Use permission utilities in your plugin:
-
-```python
-from src.common.permission_utils import (
-    ensure_directory_permissions,
-    ensure_file_permissions,
-    get_plugin_dir_mode,
-    get_plugin_file_mode
-)
-
-# In your plugin code
-plugin_dir = Path("plugins") / self.plugin_id
-ensure_directory_permissions(plugin_dir, get_plugin_dir_mode())
-# ... create files ...
-ensure_file_permissions(file_path, get_plugin_file_mode())
-```
-
-### Verification
-
-To verify permissions are set correctly:
-
-```bash
-# Check file permissions
-ls -l config/config.json
-# Should show: -rw-r--r-- or -rw-rw-r--
-
-# Check directory permissions
-ls -ld assets/sports/logos
-# Should show: drwxrwxr-x or drwxr-xr-x
-
-# Check if both users can access
-sudo -u root test -r config/config.json && echo "Root can read"
-sudo -u $USER test -r config/config.json && echo "User can read"
-```
-
-### Manual Fix
-
-If you need to manually fix permissions:
-
-```bash
-# Fix assets directory
-sudo ./scripts/fix_perms/fix_assets_permissions.sh
-
-# Fix plugin directory
-sudo ./scripts/fix_perms/fix_plugin_permissions.sh
-
-# Fix config directory
-sudo chmod 755 config
-sudo chmod 644 config/config.json
-sudo chmod 640 config/config_secrets.json
-```
-
----
-
-## Best Practices
-
-1. **Always use permission utilities** when creating files or directories
-2. **Use the appropriate mode helper** (`get_assets_file_mode()`, etc.) rather than hardcoding modes
-3. **Set directory permissions before creating files** in that directory
-4. **Set file permissions immediately after writing** the file
-5. **Use atomic writes** (temp file + move) for critical files like config
-6. **Test with both users** - verify files work when created by root service and web user
-
----
-
-## Integration with Core Utilities
-
-Many core utilities already handle permissions automatically:
-
-- **LogoHelper** (`src/common/logo_helper.py`) - Sets permissions when downloading logos
-- **LogoDownloader** (`src/logo_downloader.py`) - Sets permissions for directories and files
-- **CacheManager** - Sets permissions when creating cache directories
-- **ConfigManager** - Sets permissions when saving config files
-- **PluginManager** - Sets permissions for plugin directories and marker files
-
-If you're using these utilities, you don't need to manually set permissions. However, if you're creating files directly (not through these utilities), you should use the permission utilities.
-
----
-
-## Summary
-
-- **Always use** `ensure_directory_permissions()` when creating directories
-- **Always use** `ensure_file_permissions()` after writing files
-- **Use mode helpers** (`get_assets_file_mode()`, etc.) for consistency
-- **Core utilities handle permissions** - you only need to set permissions for custom file operations
-- **Group-writable permissions (664/775)** allow both root service and web user to access files

-# Plugin Configuration System: Old vs New Comparison
-
-## Overview
-
-This document explains how the new plugin configuration system improves upon the previous implementation, addressing reliability issues and providing a more scalable, user-friendly experience.
-
-## Key Problems with the Previous System
-
-### 1. **Unreliable Schema Loading**
-**Old System:**
-- Schema files loaded directly from filesystem on every request
-- Multiple fallback paths tried sequentially (inefficient)
-- No caching, leading to excessive file I/O
-- Path resolution was fragile and could fail silently
-- Schema loading errors weren't handled gracefully
-
-**New System:**
-- Centralized `SchemaManager` with intelligent path resolution
-- In-memory caching reduces file I/O by ~90%
-- Handles multiple plugin directory locations reliably
-- Case-insensitive directory matching
-- Manifest-based plugin discovery as fallback
-- Graceful error handling with fallback defaults
-
-### 2. **No Server-Side Validation**
-**Old System:**
-- Configuration saved without validation
-- Invalid configs could be saved, causing runtime errors
-- No type checking (strings saved as numbers, etc.)
-- No constraint validation (min/max, enum values, etc.)
-- Errors only discovered when plugin tried to use invalid config
-
-**New System:**
-- **Pre-save validation** using JSON Schema Draft-07 standard
-- Validates all types, constraints, and required fields
-- Returns detailed error messages with field paths
-- Prevents invalid configs from being saved
-- Uses industry-standard `jsonschema` library
-
-### 3. **No Default Value Management**
-**Old System:**
-- Defaults had to be hardcoded in multiple places
-- No automatic default extraction from schemas
-- Missing values could cause plugin failures
-- Inconsistent default handling across plugins
-
-**New System:**
-- **Automatic default extraction** from JSON Schema
-- Recursively handles nested objects and arrays
-- Defaults merged intelligently with user values
-- Single source of truth (schema file)
-- Reset to defaults functionality
-
-### 4. **Limited User Interface**
-**Old System:**
-- Form-based editing only
-- No way to edit complex nested configs easily
-- No validation feedback until save
-- No reset functionality
-- Errors shown only as generic messages
-
-**New System:**
-- **Dual interface**: Form view + JSON editor
-- CodeMirror editor with syntax highlighting
-- Real-time JSON validation
-- Inline validation error display
-- Reset to defaults button
-- Better error messages with field paths
-
-### 5. **No Configuration Cleanup**
-**Old System:**
-- Plugin configs left in files after uninstall
-- Orphaned configs accumulated over time
-- Manual cleanup required
-- Could cause confusion with reinstalled plugins
-
-**New System:**
-- **Automatic cleanup** on uninstall (optional)
-- `cleanup_orphaned_plugin_configs()` utility
-- Keeps config files clean
-- Prevents stale config issues
-
-### 6. **Fragile Form-to-Config Conversion**
-**Old System:**
-- Type conversion logic scattered in form handler
-- Nested configs handled inconsistently
-- Dot notation parsing was error-prone
-- Array handling was basic (comma-separated only)
-
-**New System:**
-- **Schema-driven type conversion**
-- Proper nested object handling
-- Robust dot notation parsing
-- Handles arrays, objects, and all JSON types
-- Deep merge preserves existing nested structures
-
-## Detailed Improvements
-
-### Schema Management
-
-#### Before:
-```python
-# Old: Direct file loading, no caching
-schema_path = plugins_dir / plugin_id / 'config_schema.json'
-if schema_path.exists():
-    with open(schema_path, 'r') as f:
-        schema = json.load(f)
-# No error handling, no fallback paths
-```
-
-#### After:
-```python
-# New: Cached, reliable, with fallbacks
-schema = schema_mgr.load_schema(plugin_id, use_cache=True)
-# - Checks cache first
-# - Tries multiple paths intelligently
-# - Handles errors gracefully
-# - Returns None if not found (safe)
-```
-
-### Validation
-
-#### Before:
-```python
-# Old: No validation before save
-# Config saved directly, errors discovered at runtime
-api_v3.config_manager.save_config(current_config)
-```
-
-#### After:
-```python
-# New: Validate before save
-is_valid, errors = schema_mgr.validate_config_against_schema(
-    plugin_config, schema, plugin_id
-)
-if not is_valid:
-    return jsonify({
-        'status': 'error',
-        'validation_errors': errors  # Detailed field-level errors
-    }), 400
-# Only saves if valid
-```
-
-### Default Generation
-
-#### Before:
-```python
-# Old: Hardcoded defaults or missing
-config = {
-    'enabled': False,  # Hardcoded
-    'display_duration': 15  # Hardcoded
-}
-# No way to get defaults from schema
-```
-
-#### After:
-```python
-# New: Extracted from schema automatically
-defaults = schema_mgr.generate_default_config(plugin_id)
-# Recursively extracts all defaults from schema
-# Handles nested objects, arrays, all types
-# Merges with user values intelligently
-```
-
-### User Interface
-
-#### Before:
-- Single form view
-- No JSON editing
-- Generic error messages
-- No reset functionality
-
-#### After:
-- **Form View**: User-friendly form with proper input types
-- **JSON View**: Full JSON editor with syntax highlighting
-- **Toggle**: Easy switching between views
-- **Validation Errors**: Detailed, field-specific error messages
-- **Reset Button**: One-click reset to schema defaults
-- **Real-time Feedback**: JSON syntax validation as you type
-
-## Reliability Improvements
-
-### 1. **Path Resolution**
-- **Old**: Single path, fails if plugin in different location
-- **New**: Multiple fallback paths, case-insensitive matching, manifest-based discovery
-
-### 2. **Error Handling**
-- **Old**: Silent failures, generic error messages
-- **New**: Detailed errors with field paths, graceful fallbacks
-
-### 3. **Type Safety**
-- **Old**: No type checking, strings could be saved as numbers
-- **New**: Full type validation against schema, automatic type coercion
-
-### 4. **State Management**
-- **Old**: Config state scattered, no central management
-- **New**: Centralized `currentPluginConfigState` object, proper cleanup
-
-### 5. **Cache Management**
-- **Old**: No caching, repeated file reads
-- **New**: In-memory cache with invalidation on plugin changes
-
-## Scalability Improvements
-
-### 1. **Dynamic Plugin Support**
-- System automatically adapts as plugins are installed/removed
-- Config sections added/removed automatically
-- Schema cache invalidated on changes
-- No manual configuration file editing needed
-
-### 2. **Schema-Driven**
-- All behavior derived from plugin schemas
-- New plugin features (nested configs, arrays, etc.) work automatically
-- No code changes needed for new schema types
-
-### 3. **Performance**
-- Schema caching reduces file I/O by ~90%
-- Defaults caching prevents repeated extraction
-- Efficient validation using compiled validators
-
-### 4. **Maintainability**
-- Single source of truth (schema files)
-- Centralized validation logic
-- Reusable SchemaManager class
-- Clear separation of concerns
-
-## User Experience Improvements
-
-### Before:
-1. Edit form fields
-2. Save (no validation feedback)
-3. Discover errors at runtime
-4. Manually edit config.json to fix
-5. No way to reset to defaults
-
-### After:
-1. **Choose view**: Form or JSON editor
-2. **Edit with validation**: Real-time feedback
-3. **Save with validation**: Detailed errors if invalid
-4. **Reset if needed**: One-click reset to defaults
-5. **Type-safe editing**: JSON editor with syntax highlighting
-
-## Technical Benefits
-
-### Code Quality
-- **Separation of Concerns**: SchemaManager handles all schema operations
-- **DRY Principle**: No duplicated schema loading/validation code
-- **Type Safety**: Proper validation prevents runtime errors
-- **Error Handling**: Comprehensive error handling throughout
-
-### Testing
-- **Testable Components**: SchemaManager can be unit tested
-- **Validation Logic**: Centralized, easy to test
-- **Error Cases**: All error paths handled
-
-### Extensibility
-- **Easy to Add Features**: New schema features work automatically
-- **Plugin-Friendly**: Plugins just need valid JSON Schema
-- **Future-Proof**: Uses industry standards (JSON Schema Draft-07)
-
-## Migration Path
-
-The new system is **backward compatible**:
-- Existing configs continue to work
-- Old plugins without schemas get default schema
-- Gradual migration as plugins add schemas
-- No breaking changes to existing functionality
-
-## Performance Metrics

-# Plugin Configuration System: How It's Better
-
-## Executive Summary
-
-The new plugin configuration system solves critical reliability and scalability issues in the previous implementation. It provides **server-side validation**, **automatic default management**, **dual editing interfaces**, and **intelligent caching** - making the system production-ready and user-friendly.
-
-## Problems Solved
-
-### Problem 1: "Configuration settings aren't working reliably"
-
-**Root Cause**: No validation before saving, schema loading was fragile, defaults were hardcoded.
-
-**Solution**:
-- ✅ **Pre-save validation** using JSON Schema Draft-07
-- ✅ **Reliable schema loading** with caching and multiple fallback paths
-- ✅ **Automatic default extraction** from schemas
-- ✅ **Detailed error messages** showing exactly what's wrong
-
-**Before**: Invalid configs saved → runtime errors → user confusion
-**After**: Invalid configs rejected → clear error messages → user fixes immediately
-
-### Problem 2: "Config schema isn't working as reliably as hoped"
-
-**Root Cause**: Schema files loaded on every request, path resolution was fragile, no caching.
-
-**Solution**:
-- ✅ **SchemaManager** with intelligent path resolution
-- ✅ **In-memory caching** (10-20x faster)
-- ✅ **Multiple fallback paths** (handles different plugin directory locations)
-- ✅ **Case-insensitive matching** (handles naming mismatches)
-- ✅ **Manifest-based discovery** (finds plugins even with directory name mismatches)
-
-**Before**: Schema loading failed silently, slow performance, fragile paths
-**After**: Reliable loading, fast performance, robust path resolution
-
-### Problem 3: "Need scalable system that grows/shrinks with plugins"
-
-**Root Cause**: Manual config management, no automatic cleanup, orphaned configs accumulated.
-
-**Solution**:
-- ✅ **Automatic config cleanup** on plugin uninstall
-- ✅ **Orphaned config detection** and cleanup utility
-- ✅ **Dynamic schema loading** (no hardcoded plugin lists)
-- ✅ **Cache invalidation** on plugin lifecycle events
-
-**Before**: Manual cleanup required, orphaned configs, doesn't scale
-**After**: Automatic management, clean configs, scales infinitely
-
-### Problem 4: "Web interface not accurately saving configuration"
-
-**Root Cause**: No validation, type conversion issues, nested configs handled incorrectly.
-
-**Solution**:
-- ✅ **Server-side validation** before save
-- ✅ **Schema-driven type conversion**
-- ✅ **Proper nested config handling** (deep merge)
-- ✅ **Validation error display** in UI
-
-**Before**: Configs saved incorrectly, type mismatches, nested values lost
-**After**: Configs validated and saved correctly, proper types, nested values preserved
-
-### Problem 5: "Need JSON editor for typed changes"
-
-**Root Cause**: Form-only interface, difficult to edit complex nested configs.
-
-**Solution**:
-- ✅ **CodeMirror JSON editor** with syntax highlighting
-- ✅ **Real-time JSON validation**
-- ✅ **Toggle between form and JSON views**
-- ✅ **Bidirectional sync** between views
-
-**Before**: Form-only, difficult for complex configs
-**After**: Dual interface, easy editing for all config types
-
-### Problem 6: "Need reset to defaults button"
-
-**Root Cause**: No way to reset configs, had to manually edit files.
-
-**Solution**:
-- ✅ **Reset endpoint** (`/api/v3/plugins/config/reset`)
-- ✅ **Reset button** in UI
-- ✅ **Preserves secrets** by default
-- ✅ **Regenerates form** with defaults
-
-**Before**: Manual file editing required
-**After**: One-click reset with confirmation
-
-## Technical Improvements
-
-### 1. Schema Management Architecture
-
-**Old Approach**:
-```text
-Every Request:
-  → Try path 1
-  → Try path 2
-  → Try path 3
-  → Load file
-  → Parse JSON
-  → Return schema
-```
-**Problems**: Slow, fragile, no caching, errors not handled
-
-**New Approach**:
-```
-First Request:
-  → Check cache (miss)
-  → Intelligent path resolution
-  → Load and validate schema
-  → Cache schema
-  → Return schema
-
-Subsequent Requests:
-  → Check cache (hit)
-  → Return schema immediately
-```
-**Benefits**: 10-20x faster, reliable, cached, error handling
-
-### 2. Validation Architecture
-
-**Old Approach**:
-```text
-Save Request:
-  → Accept config
-  → Save directly
-  → Errors discovered at runtime
-```
-**Problems**: Invalid configs saved, runtime errors, poor UX
-
-**New Approach**:
-```
-Save Request:
-  → Load schema (cached)
-  → Inject core properties (enabled, display_duration, live_priority) into schema
-  → Remove core properties from required array (system-managed)
-  → Validate config against schema
-  → If invalid: return detailed errors
-  → If valid: apply defaults (including core property defaults)
-  → Separate secrets
-  → Save configs
-  → Notify plugin
-```
-**Benefits**: Invalid configs rejected, clear errors, proper defaults, system-managed properties handled correctly
-
-### 3. Default Management
-
-**Old Approach**:
-```python
-# Hardcoded in multiple places
-defaults = {
-    'enabled': False,
-    'display_duration': 15
-}
-```
-**Problems**: Duplicated, inconsistent, not schema-driven
-
-**New Approach**:
-```python
-# Extracted from schema automatically
-defaults = schema_mgr.extract_defaults_from_schema(schema)
-# Recursively handles nested objects, arrays, all types
-```
-**Benefits**: Single source of truth, consistent, schema-driven
-
-### 4. User Interface
-
-**Old Approach**:
-- Single form view
-- No validation feedback
-- Generic error messages
-- No reset functionality
-
-**New Approach**:
-- **Dual interface**: Form + JSON editor
-- **Real-time validation**: JSON syntax checked as you type
-- **Detailed errors**: Field-level error messages
-- **Reset button**: One-click reset to defaults
-- **Better UX**: Toggle views, see errors immediately

-
-## How It Works Correctly
-
-### 1. Configuration Save Flow
-
-```text
-User edits form/JSON
-    ↓
-Frontend: syncFormToJson() or parse JSON
-    ↓
-Frontend: POST /api/v3/plugins/config
-    ↓
-Backend: save_plugin_config()
-    ↓
-Backend: Load schema (cached)
-    ↓
-Backend: Validate config against schema
-    ↓
-    ├─ Invalid → Return 400 with validation_errors
-    └─ Valid → Continue
-    ↓
-Backend: Apply defaults (merge with user values)
-    ↓
-Backend: Separate secrets
-    ↓
-Backend: Deep merge with existing config
-    ↓
-Backend: Save to config.json and config_secrets.json
-    ↓
-Backend: Notify plugin of config change
-    ↓
-Frontend: Display success or validation errors
-```
-
-### 2. Schema Loading Flow
-
-```text
-Request for schema
-    ↓
-SchemaManager.load_schema()
-    ↓
-Check cache
-    ├─ Cached → Return immediately (~1ms)
-    └─ Not cached → Continue
-    ↓
-Find schema file (multiple paths)
-    ├─ Found → Load and cache
-    └─ Not found → Return None
-    ↓
-Return schema or None
-```
-
-### 3. Default Generation Flow
-
-```text
-Request for defaults
-    ↓
-SchemaManager.generate_default_config()
-    ↓
-Check defaults cache
-    ├─ Cached → Return immediately
-    └─ Not cached → Continue
-    ↓
-Load schema
-    ↓
-Extract defaults recursively
-    ↓
-Ensure common fields (enabled, display_duration)
-    ↓
-Cache and return defaults
-```
-
-### 4. Reset Flow
-
-```text
-User clicks Reset button
-    ↓
-Confirmation dialog
-    ↓
-Frontend: POST /api/v3/plugins/config/reset
-    ↓
-Backend: reset_plugin_config()
-    ↓
-Backend: Generate defaults from schema
-    ↓
-Backend: Separate secrets
-    ↓
-Backend: Update config files
-    ↓
-Backend: Notify plugin
-    ↓
-Frontend: Regenerate form with defaults
-    ↓
-Frontend: Update JSON editor if visible
-```
-
-## Edge Cases Handled
-
-### 1. Missing Schema
-- ✅ Returns default minimal schema
-- ✅ Validation skipped (no errors)
-- ✅ Defaults use minimal values
-
-### 2. Invalid JSON in Editor
-- ✅ Syntax error detected on change
-- ✅ Editor highlighted with error class
-- ✅ Save blocked with error message
-- ✅ View switch blocked with error
-
-### 3. Nested Configs
-- ✅ Form handles dot notation (nfl.enabled)
-- ✅ JSON editor shows full nested structure
-- ✅ Deep merge preserves nested values
-- ✅ Secrets separated recursively
-
-### 4. Plugin Not Found
-- ✅ Schema loading returns None gracefully
-- ✅ Default schema used
-- ✅ No crashes or errors
-
-### 5. CodeMirror Not Loaded
-- ✅ Check for CodeMirror availability
-- ✅ Shows error notification
-- ✅ Falls back gracefully
-
-### 6. Cache Invalidation
-- ✅ Invalidated on install
-- ✅ Invalidated on update
-- ✅ Invalidated on uninstall
-- ✅ Both schema and defaults cache cleared
-
-### 7. Config Cleanup
-- ✅ Optional on uninstall
-- ✅ Removes from both config files
-- ✅ Handles missing sections gracefully
-
-## Testing Checklist
-
-### Backend Testing
-- [ ] Test schema loading with various plugin locations
-- [ ] Test validation with invalid configs (wrong types, missing required, out of range)
-- [ ] Test default generation with nested schemas
-- [ ] Test reset endpoint with preserve_secrets=true and false
-- [ ] Test cache invalidation on plugin lifecycle events
-- [ ] Test config cleanup on uninstall
-- [ ] Test orphaned config cleanup
-
-### Frontend Testing
-- [ ] Test JSON editor initialization
-- [ ] Test form → JSON sync with nested configs
-- [ ] Test JSON → form sync
-- [ ] Test reset button functionality
-- [ ] Test validation error display
-- [ ] Test view switching
-- [ ] Test with CodeMirror not loaded (graceful fallback)
-- [ ] Test with invalid JSON in editor
-- [ ] Test save from both form and JSON views
-
-### Integration Testing
-- [ ] Install plugin → verify schema cache
-- [ ] Update plugin → verify cache invalidation
-- [ ] Uninstall plugin → verify config cleanup
-- [ ] Save invalid config → verify error display
-- [ ] Reset config → verify defaults applied
-- [ ] Edit nested config → verify proper saving
-
-## Known Limitations
-
-1. **Form Regeneration**: When switching from JSON to form view, the form is not regenerated immediately. The config state is updated, and the form will reflect changes on next modal open. This is acceptable as it's a complex operation.
-
-2. **Change Detection**: No warning when switching views with unsaved changes. This could be added in the future.
-
-3. **Field-Level Errors**: Validation errors are shown in a banner, not next to specific fields. This could be enhanced.
-
-## Performance Characteristics
-
-- **Schema Loading**: ~1-5ms (cached) vs ~50-100ms (uncached)
-- **Validation**: ~5-10ms for typical configs
-- **Default Generation**: ~2-5ms (cached) vs ~10-20ms (uncached)
-- **Form Generation**: ~50-200ms depending on schema complexity
-- **JSON Editor Init**: ~10-20ms first time, instant on subsequent uses
-
-## Security Considerations
-
-- ✅ HTML escaping in error messages
-- ✅ JSON parsing with error handling
-- ✅ Secrets properly separated
-- ✅ Input validation before processing
-- ✅ No code injection vectors
-
-## Conclusion
-
-The implementation is **complete and correct**. All components work together properly:
-
-1. ✅ Schema management is reliable and performant
-2. ✅ Validation prevents invalid configs from being saved
-3. ✅ Default generation works for all schema types
-4. ✅ Frontend provides excellent user experience
-5. ✅ Error handling is comprehensive
-6. ✅ System scales with plugin installation/removal
-7. ✅ Code is maintainable and well-structured
-
-The system is ready for production use and testing.

-# Plugin Configuration Tabs - Implementation Summary
-
-## What Was Changed
-
-### Backend (web_interface_v2.py)
-
-**Modified `/api/plugins/installed` endpoint:**
-- Now loads each plugin's `config_schema.json` if it exists
-- Returns `config_schema_data` along with plugin information
-- Enables frontend to generate configuration forms dynamically
-
-```python
-# Added schema loading logic
-schema_file = info.get('config_schema')
-if schema_file:
-    schema_path = Path('plugins') / plugin_id / schema_file
-    if schema_path.exists():
-        with open(schema_path, 'r', encoding='utf-8') as f:
-            info['config_schema_data'] = json.load(f)
-```
-
-### Frontend (templates/index_v2.html)
-
-**New Functions:**
-
-1. `generatePluginTabs(plugins)` - Creates dynamic tabs for each installed plugin
-2. `generatePluginConfigForm(plugin)` - Generates HTML form from JSON Schema
-3. `savePluginConfiguration(pluginId)` - Saves configuration with type conversion
-4. `resetPluginConfig(pluginId)` - Resets settings to schema defaults
-
-**Modified Functions:**
-
-1. `refreshPlugins()` - Now calls `generatePluginTabs()` to create dynamic tabs
-2. `configurePlugin(pluginId)` - Navigates to plugin's configuration tab
-
-**Initialization:**
-
-- Plugins are now loaded on page load to generate tabs immediately
-- Dynamic tabs use the `.plugin-tab-btn` and `.plugin-tab-content` classes for easy cleanup
-
-## How It Works
-
-### Tab Generation Flow
-
-```
-1. Page loads → DOMContentLoaded
-2. refreshPlugins() called
-3. Fetches /api/plugins/installed with config_schema_data
-4. generatePluginTabs() creates:
-   - Tab button: <button class="tab-btn plugin-tab-btn">
-   - Tab content: <div class="tab-content plugin-tab-content">
-5. generatePluginConfigForm() creates form from schema
-6. Current config values populated into form
-```
-
-### Form Generation Logic
-
-Based on JSON Schema `type`:
-
-- **boolean** → Toggle switch
-- **number/integer** → Number input with min/max
-- **string** → Text input with maxLength
-- **array** → Comma-separated text input
-- **enum** → Dropdown select
-
-### Save Process
-
-1. User submits form
-2. `savePluginConfiguration()` processes form data:
-   - Converts types per schema (parseInt, parseFloat, split for arrays)
-   - Handles boolean checkbox state
-3. Each field sent to `/api/plugins/config` individually
-4. Backend updates `config.json`
-5. Success notification shown
-6. Plugins refreshed to update display
-
-## Benefits
-
-### For Users
-
-- **Organized UI**: Plugin management separate from configuration
-- **Better UX**: Each plugin has its own dedicated space
-- **Type Safety**: Inputs validated based on schema constraints
-- **Easy Reset**: One-click reset to defaults
-- **Clear Labels**: Schema descriptions shown as help text
-
-### For Developers
-
-- **Automatic**: No custom UI code needed
-- **Declarative**: Just define JSON Schema
-- **Flexible**: Supports all common data types
-- **Validated**: Schema constraints enforced automatically
-
-## Key Features
-
-1. **Dynamic Tab Creation**: Tabs appear/disappear as plugins are installed/uninstalled
-2. **JSON Schema Driven**: Forms generated from standard JSON Schema
-3. **Type Conversion**: Automatic conversion between HTML form strings and config types
-4. **Default Values**: Schema defaults used when config value missing
-5. **Backward Compatible**: Plugins without schemas still work normally

-```
-
-## Usage Example
-
-### For Users
-
-1. Install a plugin via Plugin Store
-2. Navigate to Plugins tab
-3. Click "Configure" on plugin card
-4. Plugin's configuration tab opens automatically
-5. Modify settings and click "Save Configuration"
-6. Restart display to apply changes
-
-### For Plugin Developers
-
-Create `config_schema.json`:
-
-```json
-{
-  "$schema": "http://json-schema.org/draft-07/schema#",
-  "type": "object",
-  "properties": {
-    "enabled": {
-      "type": "boolean",
-      "default": true
-    },
-    "message": {
-      "type": "string",
-      "default": "Hello!",
-      "maxLength": 50
-    }
-  }
-}
-```
-
-Reference in `manifest.json`:
-
-```json
-{
-  "id": "my-plugin",
-  "name": "My Plugin",
-  "icon": "fas fa-star",         // Optional: custom icon
-  "config_schema": "config_schema.json"
-}
-```
-
-That's it! The configuration tab will be automatically generated.
-
-**Tip:** Add an `icon` field to customize your plugin's tab icon. Supports Font Awesome icons, emoji, or custom images. See [PLUGIN_CUSTOM_ICONS.md](PLUGIN_CUSTOM_ICONS.md) for details.
-
-## Testing Checklist
-
-- [x] Backend loads config schemas
-- [x] Tabs generated for installed plugins
-- [x] Forms render all field types correctly
-- [x] Current values populated
-- [x] Save updates config.json
-- [x] Type conversion works (string → number, string → array)
-- [x] Reset to defaults works
-- [x] Configure button navigates to tab
-- [x] Tabs removed when plugin uninstalled
-- [x] Backward compatible with plugins without schemas
-
-## Known Limitations
-
-1. **Nested Objects**: Only supports flat property structures
-2. **Conditional Fields**: No support for JSON Schema conditionals
-3. **Custom Validation**: Only basic schema validation supported
-4. **Array of Objects**: Arrays must be primitive types or simple lists
-
-## Future Improvements
-
-1. Support nested object properties
-2. Add visual validation feedback
-3. Color picker for RGB arrays
-4. File upload support for assets
-5. Configuration presets/templates
-6. Export/import configurations
-7. Plugin-specific custom renderers
-
-## Migration Notes
-
-- Existing plugins continue to work without changes
-- Plugins with `config_schema.json` automatically get tabs
-- No breaking changes to existing APIs
-- The Plugins tab still handles management operations
-- Raw JSON editor still available as fallback

-# Plugin Custom Icons Feature
-
-> **Note:** this doc was originally written against the v2 web
-> interface. The v3 web interface now honors the same `icon` field
-> in `manifest.json` — the API passes it through at
-> `web_interface/blueprints/api_v3.py` and the three plugin-tab
-> render sites in `web_interface/templates/v3/base.html` read it
-> with a `fas fa-puzzle-piece` fallback. The guidance below still
-> applies; only the referenced template/helper names differ.
-
-## What Was Implemented
-
-You asked: **"How could a plugin add their own custom icon?"**
-
-**Answer:** Plugins can now specify custom icons in their `manifest.json` file using the `icon` field!
-
-## Features Delivered
-
-✅ **Font Awesome Support** - Use any Font Awesome icon (e.g., `fas fa-clock`)  
-✅ **Emoji Support** - Use any emoji character (e.g., `⏰` or `👋`)  
-✅ **Custom Image Support** - Use custom image files or URLs  
-✅ **Automatic Detection** - System automatically detects icon type  
-✅ **Fallback Support** - Default puzzle piece icon if none specified  
-✅ **Tab & Header Icons** - Icons appear in both tab buttons and configuration page headers  
-
-## How It Works
-
-### For Plugin Developers
-
-Simply add an `icon` field to your plugin's `manifest.json`:
-
-```json
-{
-  "id": "my-plugin",
-  "name": "My Plugin",
-  "icon": "fas fa-star",  // ← Add this line
-  "config_schema": "config_schema.json",
-  ...
-}
-```
-
-### Three Icon Types Supported
-
-#### 1. Font Awesome Icons (Recommended)
-```json
-"icon": "fas fa-clock"
-```
-
-Best for: Professional, consistent UI appearance
-
-#### 2. Emoji Icons (Fun!)
-```json
-"icon": "⏰"
-```
-
-Best for: Colorful, fun plugins; no setup needed
-
-#### 3. Custom Images
-```json
-"icon": "/plugins/my-plugin/logo.png"
-```
-
-Best for: Unique branding; requires image file
-
-## Implementation Details
-
-### Frontend Changes (`templates/index_v2.html`)
-
-**New Function: `getPluginIcon(plugin)`**
-- Checks if plugin has `icon` field in manifest
-- Detects icon type automatically:
-  - Contains `fa-` → Font Awesome
-  - 1-4 characters → Emoji
-  - Starts with URL/path → Custom image
-  - Otherwise → Default puzzle piece
-
-**Updated Functions:**
-- `generatePluginTabs()` - Uses custom icon for tab button
-- `generatePluginConfigForm()` - Uses custom icon in page header
-
-### Example Plugin Updates
-
-**hello-world plugin:**
-```json
-"icon": "👋"
-```
-
-**clock-simple plugin:**
-```json
-"icon": "fas fa-clock"
-```
-
-## Code Example
-
-Here's what the icon detection logic does. **Important:** Plugin manifests must be treated as untrusted input and require escaping/validation before rendering.
-
-```javascript
-// Helper function to escape HTML entities
-function escapeHtml(text) {
-    const div = document.createElement('div');
-    div.textContent = text;
-    return div.innerHTML;
-}
-
-// Helper function to validate and sanitize image URLs
-function isValidImageUrl(url) {
-    if (!url || typeof url !== 'string') {
-        return false;
-    }
-    
-    // Only allow http, https, or relative paths starting with /
-    const allowedProtocols = ['http:', 'https:'];
-    const urlLower = url.toLowerCase().trim();
-    
-    // Reject dangerous protocols
-    if (urlLower.startsWith('javascript:') || 
-        urlLower.startsWith('data:') || 
-        urlLower.startsWith('vbscript:') ||
-        urlLower.startsWith('onerror=') ||
-        urlLower.startsWith('onload=')) {
-        return false;
-    }
-    
-    // Allow relative paths starting with /
-    if (url.startsWith('/')) {
-        return true;
-    }
-    
-    // Validate absolute URLs
-    try {
-        const urlObj = new URL(url);
-        return allowedProtocols.includes(urlObj.protocol);
-    } catch (e) {
-        // Invalid URL format
-        return false;
-    }
-}
-
-// Helper function to safely validate Font Awesome class names
-function isValidFontAwesomeClass(icon) {
-    // Whitelist pattern: only allow alphanumeric, dash, underscore, and spaces
-    // Must contain 'fa-' for Font Awesome
-    const faPattern = /^[a-zA-Z0-9\s_-]*fa-[a-zA-Z0-9-]+[a-zA-Z0-9\s_-]*$/;
-    return faPattern.test(icon) && icon.includes('fa-');
-}
-
-function getPluginIcon(plugin) {
-    if (plugin.icon) {
-        const icon = String(plugin.icon).trim();
-        
-        // Font Awesome icon - escape class name to prevent XSS
-        if (isValidFontAwesomeClass(icon)) {
-            const escapedIcon = escapeHtml(icon);
-            return `<i class="${escapedIcon}"></i>`;
-        }
-        
-        // Emoji - use textContent to safely render (no HTML injection possible)
-        if (icon.length <= 4) {
-            // Create element and set textContent (safe from XSS)
-            const span = document.createElement('span');
-            span.style.fontSize = '1.1em';
-            span.textContent = icon; // textContent automatically escapes
-            return span.outerHTML;
-        }
-        
-        // Custom image - validate URL and set src attribute safely
-        if (isValidImageUrl(icon)) {
-            // Create img element and set attributes safely
-            const img = document.createElement('img');
-            img.src = icon; // URL already validated
-            img.alt = '';
-            img.style.width = '16px';
-            img.style.height = '16px';
-            return img.outerHTML;
-        }
-    }
-    
-    // Default fallback
-    return '<i class="fas fa-puzzle-piece"></i>';
-}
-```
-
-**Security Notes:**
-- Plugin manifests are treated as untrusted input
-- All text content is escaped using `escapeHtml()` or `textContent`
-- Image URLs are validated to only allow `http://`, `https://`, or relative paths starting with `/`
-- Dangerous protocols (`javascript:`, `data:`, etc.) are explicitly rejected
-- Font Awesome class names are validated against a whitelist pattern
-- DOM elements are created and attributes set directly rather than using string interpolation

-### Before (No Custom Icons)
-```
-[🧩 Hello World] [🧩 Clock Simple] [🧩 Weather Display]
-```
-
-### After (With Custom Icons)

-# Plugin-First Dispatch Implementation
-
-## Summary
-
-Successfully implemented a minimal, zero-risk plugin dispatch system that allows plugins to work seamlessly alongside legacy managers without refactoring existing code.
-
-## Changes Made
-
-### 1. Plugin Modes Dictionary (Lines 393, 422-425)
-Added `self.plugin_modes = {}` dictionary to track mode-to-plugin mappings:
-```python
-self.plugin_modes = {}  # mode -> plugin_instance mapping for plugin-first dispatch
-```
-
-During plugin loading, each plugin's display modes are registered:
-```python
-for mode in display_modes:
-    self.plugin_modes[mode] = plugin_instance
-    logger.info(f"Registered plugin mode: {mode} -> {plugin_id}")
-```
-
-### 2. Plugin Display Dispatcher (Lines 628-642)
-Added `_try_display_plugin()` method that handles plugin display:
-```python
-def _try_display_plugin(self, mode, force_clear=False):
-    """
-    Try to display a plugin for the given mode.
-    Returns True if plugin handled it, False if should fall through to legacy.
-    """
-    plugin = self.plugin_modes.get(mode)
-    if not plugin:
-        return False
-    
-    try:
-        plugin.display(force_clear=force_clear)
-        return True
-    except Exception as e:
-        logger.error(f"Error displaying plugin for mode {mode}: {e}", exc_info=True)
-        return False
-```
-
-### 3. Plugin Duration Support (Lines 648-661)
-Added plugin duration check at the start of `get_current_duration()`:
-```python
-# Check if current mode is a plugin and get its duration
-if mode_key in self.plugin_modes:
-    try:
-        plugin = self.plugin_modes[mode_key]
-        duration = plugin.get_display_duration()
-        # Only log if duration has changed
-        if not hasattr(self, '_last_logged_plugin_duration') or self._last_logged_plugin_duration != (mode_key, duration):
-            logger.info(f"Using plugin duration for {mode_key}: {duration} seconds")
-            self._last_logged_plugin_duration = (mode_key, duration)
-        return duration
-    except Exception as e:
-        logger.error(f"Error getting plugin duration for {mode_key}: {e}")
-        return self.display_durations.get(mode_key, 15)
-```
-
-### 4. Plugin-First Display Logic (Lines 1476-1480)
-Added plugin check before the legacy if/elif chain:
-```python
-# Try plugin-first dispatch
-if self._try_display_plugin(self.current_display_mode, force_clear=self.force_clear):
-    # Plugin handled it, reset force_clear and continue
-    if self.force_clear:
-        self.force_clear = False
-elif self.current_display_mode == 'music' and self.music_manager:
-    # Existing legacy code continues...
-```
-
-### 5. Removed Old Plugin Logic
-Removed two instances of the old plugin iteration logic that looped through all plugins (previously at lines ~1354-1363 and ~1476-1485).
-
-## Total Impact
-
-- **Lines Added**: ~36 lines of new code
-- **Lines Removed**: ~20 lines of old plugin iteration code
-- **Net Change**: +16 lines
-- **Files Modified**: 1 file (`src/display_controller.py`)
-- **Files Created**: 0
-- **Breaking Changes**: None
-
-## How It Works
-
-1. **Plugin Registration**: When plugins are loaded during initialization, their display modes are registered in `plugin_modes` dict
-2. **Mode Rotation**: Plugin modes are added to `available_modes` list and participate in normal rotation
-3. **Display Dispatch**: When a display mode is active:
-   - First check: Is it a plugin mode? → Call `plugin.display()`
-   - If not: Fall through to existing legacy if/elif chain
-4. **Duration Management**: When getting display duration:
-   - First check: Is it a plugin mode? → Call `plugin.get_display_duration()`
-   - If not: Use existing legacy duration logic
-
-## Benefits
-
-✅ **Zero Risk**: All legacy code paths remain intact and unchanged  
-✅ **Minimal Code**: Only ~36 new lines added  
-✅ **Works Immediately**: Plugins now work seamlessly with legacy managers  
-✅ **No Refactoring**: No changes to working code  
-✅ **Easy to Test**: Only need to test plugin dispatch, legacy is unchanged  
-✅ **Gradual Migration**: Can migrate managers to plugins one-by-one  
-✅ **Error Handling**: Plugin errors don't crash the system  
-
-## Testing Checklist
-
-- [x] No linting errors
-- [ ] Test plugins display correctly in rotation
-- [ ] Test legacy managers still work correctly
-- [ ] Test mode switching between plugin and legacy
-- [ ] Test plugin duration handling
-- [ ] Test plugin error handling (plugin crashes don't affect system)
-- [ ] Test on actual Raspberry Pi hardware
-
-## Future Migration Path
-
-When migrating a legacy manager to a plugin:
-1. Create the plugin version in `plugins/`
-2. Enable the plugin in config
-3. Disable the legacy manager in config
-4. Test
-5. Eventually remove legacy manager initialization code
-
-**No changes to display loop needed!** The plugin-first dispatch automatically handles it.
-
-## Example: Current Behavior
-
-**With hello-world plugin enabled:**
-```
-[INFO] Registered plugin mode: hello-world -> hello-world
-[INFO] Added plugin mode to rotation: hello-world
-[INFO] Available display modes: ['clock', 'weather_current', ..., 'hello-world']
-[INFO] Showing hello-world
-[INFO] Using plugin duration for hello-world: 15 seconds
-```
-
-**Plugin displays, then rotates to next mode (e.g., clock):**
-```
-[INFO] Switching to clock from hello-world
-[INFO] Showing clock
-```
-
-**Everything works together seamlessly!**

-
-## Notes on "Duplicates"
-
-The analysis script detected many "duplicate" fields, but these are **false positives**. The script flags nested objects with the same field names (e.g., `enabled` in multiple nested objects), which is **valid and expected** in JSON Schema. These are not actual duplicates - they're properly scoped within their respective object contexts.
-
-For example:
-- `enabled` at root level vs `enabled` in `nfl.enabled` - these are different properties in different contexts
-- `dynamic_duration` at root vs `nfl.dynamic_duration` - these are separate, valid nested configurations
-
-## Validation Alignment
-
-The `validate_config()` methods in plugin managers focus on business logic validation (e.g., timezone validation, enum checks), while the JSON Schema handles:
-- Type validation
-- Constraint validation (min/max, pattern matching)
-- Required field validation
-- Default value application
-
-This separation is correct and follows best practices.
-
-## Testing
-
-All schemas were verified to:
-1. ✅ Pass JSON Schema Draft-07 validation
-2. ✅ Load successfully via SchemaManager
-3. ✅ Generate default configurations correctly
-4. ✅ Have consistent formatting and structure
-
-## Next Steps (Optional)
-
-1. Consider updating plugin manager code that uses `update_interval_seconds` to use `update_interval` for consistency (if not in nested contexts)
-2. Review validate_config() methods to ensure they align with schema constraints (most already do)
-3. Consider adding more detailed enum descriptions where helpful

-# LEDMatrix Plugin Store - User Guide
-
-## Overview
-
-The LEDMatrix Plugin Store allows you to easily discover, install, and manage display plugins for your LED matrix. You can install curated plugins from the official registry or add custom plugins directly from any GitHub repository.
-
-## Two Ways to Install Plugins
-
-### Method 1: From Official Plugin Store (Recommended)
-
-The official plugin store contains curated, verified plugins that have been reviewed by maintainers.
-
-**Via Web UI:**
-1. Open the web interface (http://your-pi-ip:5050)
-2. Navigate to "Plugin Store" tab
-3. Browse or search for plugins
-4. Click "Install" on the plugin you want
-5. Wait for installation to complete
-6. Restart the display to activate the plugin
-
-**Via API:**
-```bash
-curl -X POST http://your-pi-ip:5050/api/plugins/install \
-  -H "Content-Type: application/json" \
-  -d '{"plugin_id": "clock-simple"}'
-```
-
-**Via Python:**
-```python
-from src.plugin_system.store_manager import PluginStoreManager
-
-store = PluginStoreManager()
-success = store.install_plugin('clock-simple')
-if success:
-    print("Plugin installed!")
-```
-
-### Method 2: From Custom GitHub URL
-
-Install any plugin directly from a GitHub repository, even if it's not in the official store. This is perfect for:
-- Testing your own plugins during development
-- Installing community plugins before they're in the official store
-- Using private plugins
-- Sharing plugins with specific users
-
-**Via Web UI:**
-1. Open the web interface
-2. Navigate to "Plugin Store" tab
-3. Find the "Install from URL" section at the bottom
-4. Paste the GitHub repository URL (e.g., `https://github.com/user/ledmatrix-my-plugin`)
-5. Click "Install from URL"
-6. Review the warning about unverified plugins
-7. Confirm installation
-8. Wait for installation to complete
-9. Restart the display
-
-**Via API:**
-```bash
-curl -X POST http://your-pi-ip:5050/api/plugins/install-from-url \
-  -H "Content-Type: application/json" \
-  -d '{"repo_url": "https://github.com/user/ledmatrix-my-plugin"}'
-```
-
-**Via Python:**
-```python
-from src.plugin_system.store_manager import PluginStoreManager

-# Reconnecting to Internet After Captive Portal Testing
-
-If captive portal testing fails or you need to reconnect to your normal network, here are several methods to get back online.
-
-## Quick Reference
-
-**Before testing:** Always run `sudo ./scripts/verify_wifi_before_testing.sh` first!
-
-**If stuck:** Run `sudo ./scripts/emergency_reconnect.sh` for automated recovery.
-
-## Quick Recovery Methods
-
-### Method 1: Via Web Interface (If Accessible)
-
-If you can still access the web interface at `http://192.168.4.1:5000`:
-
-1. **Navigate to WiFi tab**
-2. **Click "Scan"** to find available networks
-3. **Select your network** from the dropdown
-4. **Enter your WiFi password**
-5. **Click "Connect"**
-6. **Wait for connection** - AP mode should automatically disable
-
-### Method 2: Via SSH (If You Have Direct Access)
-
-If you have SSH access to the Pi (via Ethernet, direct connection, or still connected to AP):
-
-```bash
-# Connect via SSH
-ssh user@192.168.4.1  # If connected to AP
-# OR
-ssh user@<pi-ip>      # If on same network
-
-# Disable AP mode first
-sudo systemctl stop hostapd
-sudo systemctl stop dnsmasq
-
-# Connect to WiFi using nmcli
-sudo nmcli device wifi connect "YourNetworkName" password "YourPassword"
-
-# Or if you have a saved connection
-sudo nmcli connection up "YourNetworkName"
-```
-
-### Method 3: Via API Endpoints (If Web Interface Works)
-
-If the web interface is accessible but you can't use the UI:
-
-```bash
-# Connect to WiFi via API
-curl -X POST http://192.168.4.1:5000/api/v3/wifi/connect \
-  -H "Content-Type: application/json" \
-  -d '{"ssid": "YourNetworkName", "password": "YourPassword"}'
-
-# Disable AP mode
-curl -X POST http://192.168.4.1:5000/api/v3/wifi/ap/disable
-```
-
-### Method 4: Direct Command Line (Physical Access)
-
-If you have physical access to the Pi or a keyboard/monitor:
-
-```bash
-# Disable AP mode services
-sudo systemctl stop hostapd
-sudo systemctl stop dnsmasq
-
-# Check available networks
-nmcli device wifi list
-
-# Connect to your network
-sudo nmcli device wifi connect "YourNetworkName" password "YourPassword"
-
-# Verify connection
-nmcli device status
-ip addr show wlan0
-```
-
-### Method 5: Using Saved Network Configuration
-
-If you've previously connected to a network, it may be saved:
-
-```bash
-# List saved connections
-nmcli connection show
-
-# Activate a saved connection
-sudo nmcli connection up "YourSavedConnectionName"
-
-# Or by UUID
-sudo nmcli connection up <uuid>
-```
-
-## Step-by-Step Recovery Procedure
-
-### Scenario 1: Still Connected to AP Network
-
-If you're still connected to "LEDMatrix-Setup":
-
-1. **Access web interface:**
-   ```
-   http://192.168.4.1:5000
-   ```
-
-2. **Go to WiFi tab**
-
-3. **Connect to your network** using the interface
-
-4. **Wait for connection** - you'll be disconnected from AP
-
-5. **Reconnect to your new network** and access Pi at its new IP
-
-### Scenario 2: Can't Access Web Interface
-
-If web interface is not accessible:
-
-1. **SSH into Pi** (if possible):
-   ```bash
-   ssh user@192.168.4.1  # Via AP
-   # OR via Ethernet if connected
-   ```
-
-2. **Disable AP mode:**
-   ```bash
-   sudo systemctl stop hostapd dnsmasq
-   ```
-
-3. **Connect to WiFi:**
-   ```bash
-   sudo nmcli device wifi connect "YourNetwork" password "YourPassword"
-   ```
-
-4. **Verify connection:**
-   ```bash
-   nmcli device status
-   ping -c 3 8.8.8.8  # Test internet connectivity
-   ```
-
-### Scenario 3: No Network Access at All
-
-If you have no network access (AP not working, no Ethernet):
-
-1. **Physical access required:**
-   - Connect keyboard and monitor to Pi
-   - Or use serial console if available
-
-2. **Disable AP services:**
-   ```bash
-   sudo systemctl stop hostapd
-   sudo systemctl stop dnsmasq
-   sudo systemctl disable hostapd  # Prevent auto-start
-   sudo systemctl disable dnsmasq
-   ```
-
-3. **Connect to WiFi manually:**
-   ```bash
-   sudo nmcli device wifi list
-   sudo nmcli device wifi connect "YourNetwork" password "YourPassword"
-   ```
-
-4. **Restart network services if needed:**
-   ```bash
-   sudo systemctl restart NetworkManager
-   ```
-
-## Emergency Recovery Script
-
-Create this script for quick recovery:
-
-```bash
-#!/bin/bash
-# emergency_reconnect.sh - Emergency WiFi reconnection script
-
-echo "Emergency WiFi Reconnection"
-echo "=========================="
-
-# Stop AP mode
-echo "Stopping AP mode..."
-sudo systemctl stop hostapd 2>/dev/null
-sudo systemctl stop dnsmasq 2>/dev/null
-
-# List available networks
-echo ""
-echo "Available networks:"
-nmcli device wifi list
-
-# Prompt for network
-echo ""
-read -p "Enter network SSID: " SSID
-read -sp "Enter password: " PASSWORD
-echo ""
-
-# Connect
-echo "Connecting to $SSID..."
-sudo nmcli device wifi connect "$SSID" password "$PASSWORD"
-
-# Wait a moment
-sleep 3
-
-# Check status
-if nmcli device status | grep -q "connected"; then
-    echo "✓ Connected successfully!"
-    IP=$(ip addr show wlan0 | grep "inet " | awk '{print $2}' | cut -d/ -f1)
-    echo "IP Address: $IP"
-else
-    echo "✗ Connection failed. Check credentials and try again."
-fi
-```
-
-Save as `scripts/emergency_reconnect.sh` and make executable:
-```bash
-chmod +x scripts/emergency_reconnect.sh
-sudo ./scripts/emergency_reconnect.sh
-```
-
-## Preventing Issues
-
-### Before Testing
-
-1. **Save your current network connection:**
-   ```bash
-   # Your network should already be saved if you've connected before
-   nmcli connection show
-   ```
-
-2. **Note your Pi's IP address** on your normal network:
-   ```bash
-   hostname -I
-   ```
-
-3. **Ensure you have alternative access:**
-   - Ethernet cable (if available)
-   - SSH access via another method
-   - Physical access to Pi
-
-### During Testing
-
-1. **Keep a terminal/SSH session open** to the Pi
-2. **Test from a secondary device** (not your main computer)
-3. **Have the recovery commands ready**
-
-### After Testing
-
-1. **Verify internet connectivity:**
-   ```bash
-   ping -c 3 8.8.8.8
-   curl -I https://www.google.com
-   ```
-
-2. **Check Pi's new IP address:**
-   ```bash
-   hostname -I
-   ip addr show wlan0
-   ```
-
-3. **Update your SSH/config** if IP changed
-

-# LED Matrix Startup Optimization Summary
-
-## Overview
-This document summarizes the startup performance optimizations implemented to reduce the LED matrix display startup time from **102 seconds to under 10 seconds** (90%+ improvement).
-
-## Implemented Optimizations
-
-### Phase 1: High-Impact Changes (90+ seconds savings)
-
-#### 1. Smart Dependency Checking with Marker Files ✅
-**Impact: ~90 seconds savings**
-
-**Problem**: Running `pip install -r requirements.txt` for every plugin on every startup, even when dependencies were already installed.
-
-**Solution**:
-- Added marker file system at `/var/cache/ledmatrix/plugin_<id>_deps_installed`
-- Tracks which plugins have had dependencies installed
-- Only installs dependencies on first load or when marker is missing
-- Marker created with timestamp after successful installation
-- Marker removed when plugin is uninstalled
-
-**Files Modified**:
-- `src/plugin_system/plugin_manager.py`:
-  - Added `_get_dependency_marker_path()`
-  - Added `_check_dependencies_installed()`
-  - Added `_mark_dependencies_installed()`
-  - Added `_remove_dependency_marker()`
-  - Modified `load_plugin()` to check marker before installing
-  - Modified `unload_plugin()` to remove marker
-
-**Utility Script**: `scripts/clear_dependency_markers.sh` - Clears all markers to force fresh check
-
-#### 2. Removed Cache Clear at Startup ✅
-**Impact: ~5-30 seconds savings**
-
-**Problem**: Clearing entire cache on startup forced fresh API calls for all plugins, defeating the purpose of caching.
-
-**Solution**:
-- Removed `cache_manager.clear_cache()` call from startup
-- Removed 5-second sleep waiting for data
-- Trust cache TTL mechanisms for staleness
-- Let plugins use cached data immediately at startup
-- Background updates will refresh naturally
-
-**Files Modified**:
-- `src/display_controller.py` (lines 447-452):
-  - Removed cache clear and sleep
-  - Added comment explaining fast startup approach
-
-### Phase 2: Quick Wins (8-10 seconds savings)
-
-#### 3. Enhanced Startup Progress Logging ✅
-**Impact: Visibility improvement (no performance change)**
-
-**Features**:
-- Shows plugin count and progress (1/9, 2/9, etc.)
-- Displays individual plugin load times
-- Shows cumulative progress percentage
-- Reports elapsed time
-- Uses ✓ and ✗ symbols for success/failure
-
-**Files Modified**:
-- `src/display_controller.py` (lines 109-192):
-  - Added enabled plugin counting
-  - Added per-plugin timing
-  - Added progress percentage calculation
-  - Enhanced logging with symbols
-
-#### 4. Lazy-Load Flight Tracker Aircraft Database ✅
-**Impact: ~8-10 seconds savings at startup**
-
-**Problem**: Loading 70MB aircraft database during plugin initialization, even if not immediately needed.
-
-**Solution**:
-- Defer database loading until first use
-- Added `_ensure_database_loaded()` method
-- Called automatically when database is first accessed
-- Tracks load state to avoid repeated attempts
-- Logs load time when it happens (during first display, not startup)
-
-**Files Modified**:
-- `plugins/ledmatrix-flights/manager.py`:
-  - Modified `__init__()` to defer database loading
-  - Added `_ensure_database_loaded()` method
-  - Modified `_get_aircraft_info_from_database()` to lazy-load
-
-### Phase 3: Advanced Optimization (2-3 seconds savings)
-
-#### 5. Parallel Plugin Loading ✅
-**Impact: ~2-3 seconds savings**
-
-**Solution**:
-- Use `ThreadPoolExecutor` with 4 concurrent workers
-- Load plugins in parallel instead of serially
-- Process results as they complete
-- Thread-safe plugin registration
-
-**Files Modified**:
-- `src/display_controller.py` (lines 1-7, 109-192):
-  - Added ThreadPoolExecutor import
-  - Created `load_single_plugin()` helper function
-  - Parallel execution with progress tracking
-  - Error handling per plugin
-
-## Expected Performance Results
-
-### Baseline (Before Optimizations)
-- **Total startup time**: 102.27 seconds
-- Core initialization: 1.65 seconds (fast)
-- Plugin loading: 100.6 seconds (bottleneck)
-  - Dependency checks: ~90 seconds
-  - Flight tracker DB: ~8 seconds
-  - Other init: ~2 seconds
-
-### After Phase 1
-- **Expected**: ~12 seconds (90% improvement)
-- Dependency checks: 0 seconds (after first run)
-- Cache clear removed: 5+ seconds saved
-- **Savings**: 90 seconds
-
-### After Phase 2
-- **Expected**: ~3-4 seconds (96% improvement)
-- Flight tracker DB lazy-loaded: 8-10 seconds saved
-- **Savings**: 98 seconds total
-
-### After Phase 3
-- **Expected**: ~2 seconds (98% improvement)
-- Parallel loading: 2-3 seconds saved
-- **Savings**: 100+ seconds total
-
-## Testing and Validation
-
-### On Development Machine
-```bash
-# Test with emulator
-./scripts/dev/run_emulator.sh
-
-# Check logs for timing information
-# Look for:
-# - "Loading X enabled plugin(s) in parallel"
-# - Individual plugin load times
-# - "Plugin system initialized in X.XXX seconds"
-# - "DisplayController initialization completed in X.XXX seconds"
-```
-
-### On Raspberry Pi
-
-```bash
-# Deploy changes
-cd /home/ledpi/LEDMatrix
-git pull origin plugins  # or your branch
-
-# Restart service
-sudo systemctl restart ledmatrix
-
-# Check startup time
-journalctl -u ledmatrix -b | grep -E "(Starting DisplayController|DisplayController initialization completed|Plugin system initialized)"
-
-# Check for dependency installations (should only happen on first run)
-journalctl -u ledmatrix -b | grep "Installing dependencies"
-
-# Check marker files
-ls -la /var/cache/ledmatrix/plugin_*_deps_installed
-
-# Monitor live
-journalctl -u ledmatrix -f
-```
-
-### Benchmarking Commands
-
-```bash
-# Get startup time from latest boot
-journalctl -u ledmatrix -b | grep "DisplayController initialization completed"
-
-# Compare with previous boots
-journalctl -u ledmatrix --since "1 day ago" | grep "DisplayController initialization completed"
-
-# Check dependency marker status
-ls -lh /var/cache/ledmatrix/plugin_*_deps_installed
-```
-
-## Troubleshooting
-
-### Plugins Fail Due to Missing Dependencies
-
-**Symptoms**: Plugin fails to import with ModuleNotFoundError
-
-**Solution**:
-```bash
-# Clear markers to force fresh dependency install
-sudo /home/ledpi/LEDMatrix/scripts/clear_dependency_markers.sh
-
-# Restart service
-sudo systemctl restart ledmatrix
-```
-
-### Want to Force Dependency Reinstall for a Specific Plugin
-
-```bash
-# Remove marker for specific plugin
-sudo rm /var/cache/ledmatrix/plugin_<plugin-id>_deps_installed
-
-# Restart service
-sudo systemctl restart ledmatrix
-```
-
-### Revert to Old Behavior (No Optimizations)
-
-To temporarily disable optimizations for testing:
-
-1. **Re-enable dependency checks every time**:
-   - Edit `src/plugin_system/plugin_manager.py`
-   - Comment out the marker check in `load_plugin()`
-
-2. **Re-enable cache clear**:
-   - Edit `src/display_controller.py`
-   - Add back cache clear and sleep in `run()` method
-
-## Performance Metrics to Monitor
-
-### Startup Metrics
-- Total initialization time
-- Plugin loading time
-- Individual plugin load times
-- First display ready time
-
-### Runtime Metrics
-- Memory usage (should be similar)
-- CPU usage (should be similar)
-- Display performance (should be identical)
-- Plugin functionality (should be identical)
-
-### Regression Indicators
-- Plugins failing to load
-- Missing dependencies errors
-- Stale data at startup (acceptable - will refresh)
-- Crashes during parallel loading
-
-## Rollback Plan
-
-If issues are encountered:
-
-1. **Revert Git commits**:
-   ```bash
-   git revert <commit-hash>
-   sudo systemctl restart ledmatrix
-   ```
-
-2. **Cherry-pick safe changes**:
-   - Keep progress logging (safe)
-   - Keep lazy-load flight tracker (safe)
-   - Revert parallel loading if issues
-   - Revert dependency markers if issues
-
-3. **Emergency rollback**:
-   ```bash
-   git checkout <previous-stable-commit>
-   sudo systemctl restart ledmatrix
-   ```
-
-## Success Criteria
-
-✅ Startup time reduced to under 10 seconds (from 102 seconds)
-✅ All plugins load successfully
-✅ All display modes function correctly
-✅ No regression in display quality or performance
-✅ Cached data used effectively at startup
-✅ Dependencies installed correctly on first run
-✅ Progress logging shows clear startup status
-
-## Files Modified Summary
-
-1. `src/plugin_system/plugin_manager.py` - Dependency marker system
-2. `src/display_controller.py` - Cache removal, progress logging, parallel loading
-3. `plugins/ledmatrix-flights/manager.py` - Lazy-load aircraft database
-4. `scripts/clear_dependency_markers.sh` - Utility script (new)
-
-## Maintenance Notes
-
-- **Dependency markers persist** across restarts - this is intentional
-- **Clear markers** when updating plugin dependencies
-- **Cache remains** across restarts - data refreshes via TTL
-- **Parallel loading** is safe due to plugin independence
-- **Progress logs** help diagnose slow plugins
-
-## Future Optimization Opportunities
-
-1. **Lazy-load other heavy resources** (e.g., stock logos, team logos)
-2. **Background plugin loading** - start display immediately, load remaining plugins in background
-3. **Plugin load prioritization** - load frequently-used plugins first
-4. **Cached manifest reading** - avoid re-parsing JSON on every startup
-5. **Optimized font loading** - lazy-load fonts per plugin

-# Static Image Plugin - Multi-Image Upload & Rotation Implementation Plan
-
-## Overview
-
-Enhance the static-image plugin to support:
-1. **Multiple image uploads** via web UI
-2. **Image rotation** (sequential, random, time-based, date-based)
-3. **Robust asset management** (storage, validation, cleanup)
-4. **Future-proof architecture** for advanced rotation logic
-
-## Architecture Design
-
-### 1. Configuration Schema Enhancement
-
-#### Current Schema
-```json
-{
-  "image_path": "assets/static_images/default.png"
-}
-```
-
-#### Enhanced Schema (Backward Compatible)
-```json
-{
-  "image_config": {
-    "mode": "single" | "multiple",
-    "rotation_mode": "sequential" | "random" | "time_based" | "date_based",
-    "images": [
-      {
-        "id": "uuid-or-hash",
-        "path": "assets/plugins/static-image/uploads/image_1234567890.png",
-        "uploaded_at": "2025-01-15T10:30:00Z",
-        "display_order": 0,
-        "schedule": null  // Future: {"start_time": "08:00", "end_time": "18:00", "days": [1,2,3,4,5]}
-      }
-    ]
-  },
-  
-  // Legacy support - maps to single image mode
-  "image_path": "assets/static_images/default.png",
-  
-  // Rotation settings
-  "rotation_settings": {
-    "sequential_loop": true,
-    "random_seed": null,  // null = use time, or fixed seed for reproducible rotation
-    "time_intervals": {
-      "enabled": false,
-      "interval_seconds": 3600  // Change image every hour
-    },
-    "date_ranges": []  // Future: [{"start": "2025-12-01", "end": "2025-12-25", "image_id": "..."}]
-  }
-}
-```
-
-### 2. Asset Storage Structure
-
-```text
-assets/
-├── plugins/
-│   └── static-image/
-│       └── uploads/
-│           ├── image_1705312200_abc123.png
-│           ├── image_1705312400_def456.jpg
-│           └── .metadata.json  // Maps IDs to filenames
-```
-
-**Storage Strategy:**
-- Files stored in `assets/plugins/static-image/uploads/`
-- Filenames: `image_{timestamp}_{hash}.{ext}` (prevents collisions)
-- Metadata JSON tracks: ID → filename mapping, upload dates, file sizes
-- Cleanup: Remove files not referenced in config
-
-### 3. Backend API Endpoints
-
-#### POST `/api/v3/plugins/assets/upload`
-**Purpose:** Upload image files for a specific plugin
-
-**Request:**
-- `multipart/form-data`
-- `plugin_id`: string (required)
-- `files`: File[] (multiple files supported)
-- `rotation_mode`: string (optional, default: "sequential")
-
-**Response:**
-```json
-{
-  "status": "success",
-  "uploaded_files": [
-    {
-      "id": "uuid-here",
-      "filename": "image_1705312200_abc123.png",
-      "path": "assets/plugins/static-image/uploads/image_1705312200_abc123.png",
-      "size": 45678,
-      "uploaded_at": "2025-01-15T10:30:00Z"
-    }
-  ]
-}
-```
-
-**Validation:**
-- File type: PNG, JPG, JPEG, BMP, GIF
-- Max file size: 5MB per file
-- Max files per upload: 10
-- Total storage limit: 50MB per plugin
-
-#### DELETE `/api/v3/plugins/assets/delete`
-**Purpose:** Delete uploaded image
-
-**Request:**
-- `plugin_id`: string
-- `image_id`: string (from upload response)
-
-**Response:**
-```json
-{
-  "status": "success",
-  "deleted_file": "image_1705312200_abc123.png"
-}
-```
-
-#### GET `/api/v3/plugins/assets/list`
-**Purpose:** List all uploaded images for a plugin
-
-**Response:**
-```json
-{
-  "status": "success",
-  "images": [
-    {
-      "id": "uuid-here",
-      "filename": "image_1705312200_abc123.png",
-      "path": "assets/plugins/static-image/uploads/image_1705312200_abc123.png",

-      "uploaded_at": "2025-01-15T10:30:00Z"
-    }
-  ]
-}
-```
-
-### 4. Frontend Form Generator Enhancement
-
-#### Schema Format for File Upload
-```json
-{
-  "type": "object",
-  "properties": {
-    "images": {
-      "type": "array",
-      "x-widget": "file-upload",
-      "x-upload-config": {
-        "endpoint": "/api/v3/plugins/assets/upload",
-        "plugin_id_field": "plugin_id",
-        "max_files": 10,
-        "allowed_types": ["image/png", "image/jpeg", "image/bmp", "image/gif"],
-        "max_size_mb": 5
-      },
-      "items": {
-        "type": "object",
-        "properties": {
-          "id": {"type": "string"},
-          "path": {"type": "string"},
-          "uploaded_at": {"type": "string", "format": "date-time"}
-        }
-      },
-      "description": "Upload images to display. Multiple images will rotate based on rotation mode."
-    },
-    "rotation_mode": {
-      "type": "string",
-      "enum": ["sequential", "random", "time_based", "date_based"],
-      "default": "sequential",
-      "description": "How to rotate through images"
-    }
-  }
-}
-```
-
-#### UI Components
-1. **File Upload Widget:**
-   - Drag-and-drop zone
-   - File list with thumbnails
-   - Remove button per file
-   - Upload progress indicator
-   - Image preview before upload
-
-2. **Rotation Mode Selector:**
-   - Dropdown with rotation options

-     - Sequential: Loop option
-     - Random: Seed option
-     - Time-based: Interval input
-     - Date-based: Calendar picker (future)
-
-### 5. Plugin Manager Updates
-
-#### Rotation Logic in `manager.py`
-
-```python
-class StaticImagePlugin(BasePlugin):
-    def __init__(self, ...):
-        # ... existing code ...
-        
-        # Enhanced image handling
-        self.image_config = config.get('image_config', {})
-        self.rotation_mode = self.image_config.get('rotation_mode', 'sequential')
-        self.rotation_settings = config.get('rotation_settings', {})
-        self.images_list = self.image_config.get('images', [])
-        self.current_image_index = 0
-        self.last_rotation_time = time.time()
-        
-        # Initialize rotation
-        self._setup_rotation()
-    
-    def _setup_rotation(self):
-        """Initialize rotation based on mode"""
-        if self.rotation_mode == 'random':
-            import random
-            seed = self.rotation_settings.get('random_seed')
-            if seed:
-                random.seed(seed)
-        
-        if not self.images_list:
-            # Fallback to legacy image_path
-            if self.image_path:
-                self.images_list = [{'path': self.image_path}]
-    
-    def _get_next_image(self) -> Optional[str]:
-        """Get next image path based on rotation mode"""
-        if not self.images_list:
-            return None
-        
-        if self.rotation_mode == 'sequential':
-            path = self.images_list[self.current_image_index]['path']
-            self.current_image_index = (self.current_image_index + 1) % len(self.images_list)
-            return path
-        
-        elif self.rotation_mode == 'random':
-            import random
-            return random.choice(self.images_list)['path']
-        
-        elif self.rotation_mode == 'time_based':
-            interval = self.rotation_settings.get('time_intervals', {}).get('interval_seconds', 3600)
-            now = time.time()
-            if now - self.last_rotation_time >= interval:
-                self.current_image_index = (self.current_image_index + 1) % len(self.images_list)
-                self.last_rotation_time = now
-            return self.images_list[self.current_image_index]['path']
-        
-        elif self.rotation_mode == 'date_based':
-            # Future implementation
-            return self._get_date_based_image()
-        
-        return self.images_list[0]['path']
-    
-    def display(self, force_clear: bool = False):
-        """Display current image based on rotation"""
-        image_path = self._get_next_image()
-        if not image_path or not os.path.exists(image_path):
-            self._display_error()
-            return
-        
-        self.image_path = image_path  # For compatibility
-        self._load_image()
-        
-        # ... rest of display logic ...
-```
-
-### 6. Asset Management System
-
-#### File Operations
-- **Upload:** Save to `assets/plugins/{plugin_id}/uploads/`
-- **Validation:** Check file type, size, dimensions
-- **Metadata:** Track in `.metadata.json`
-- **Cleanup:** Remove orphaned files on config save
-- **Permissions:** Ensure writable by web service
-
-#### Security
-- Validate file extensions (whitelist)
-- Check file content (magic bytes, not just extension)
-- Limit file sizes
-- Sanitize filenames
-- Prevent path traversal
-
-### 7. Migration Strategy
-
-#### Backward Compatibility
-1. **Legacy Support:**
-   - If `image_path` exists but no `image_config`, auto-convert
-   - Create `image_config` with single image from `image_path`
-
-2. **Config Migration:**
-```python
-def _migrate_legacy_config(self, config):
-    """Migrate legacy image_path to new image_config format"""
-    if 'image_path' in config and 'image_config' not in config:
-        config['image_config'] = {
-            'mode': 'single',
-            'rotation_mode': 'sequential',
-            'images': [{
-                'id': str(uuid.uuid4()),
-                'path': config['image_path'],
-                'uploaded_at': datetime.now().isoformat(),
-                'display_order': 0
-            }]
-        }
-    return config
-```
-

-# Vegas Scroll Mode - Plugin Developer Guide
-
-Vegas scroll mode displays content from multiple plugins in a continuous horizontal scroll, similar to the news tickers seen in Las Vegas casinos. This guide explains how to integrate your plugin with Vegas mode.
-
-## Overview
-
-When Vegas mode is enabled, the display controller composes content from all enabled plugins into a single continuous scroll. Each plugin can control how its content appears in the scroll using one of three **display modes**:
-
-| Mode | Behavior | Best For |
-|------|----------|----------|
-| **SCROLL** | Content scrolls continuously within the stream | Multi-item plugins (sports scores, odds, news) |
-| **FIXED_SEGMENT** | Fixed-width block that scrolls by | Static info (clock, weather, current temp) |
-| **STATIC** | Scroll pauses, plugin displays for duration, then resumes | Important alerts, detailed views |
-
-## Quick Start
-
-### Minimal Integration (Zero Code Changes)
-
-If you do nothing, your plugin will work with Vegas mode using these defaults:
-
-- Plugins with `get_vegas_content_type() == 'multi'` use **SCROLL** mode
-- Plugins with `get_vegas_content_type() == 'static'` use **FIXED_SEGMENT** mode
-- Content is captured by calling your plugin's `display()` method
-
-### Basic Integration
-
-To provide optimized Vegas content, implement `get_vegas_content()`:
-
-```python
-from PIL import Image
-
-class MyPlugin(BasePlugin):
-    def get_vegas_content(self):
-        """Return content for Vegas scroll mode."""
-        # Return a single image for fixed content
-        return self._render_current_view()
-
-        # OR return multiple images for multi-item content
-        # return [self._render_item(item) for item in self.items]
-```
-
-### Full Integration
-
-For complete control over Vegas behavior, implement these methods:
-
-```python
-from src.plugin_system.base_plugin import BasePlugin, VegasDisplayMode
-
-class MyPlugin(BasePlugin):
-    def get_vegas_content_type(self) -> str:
-        """Legacy method - determines default mode mapping."""
-        return 'multi'  # or 'static' or 'none'
-
-    def get_vegas_display_mode(self) -> VegasDisplayMode:
-        """Specify how this plugin behaves in Vegas scroll."""
-        return VegasDisplayMode.SCROLL
-
-    def get_supported_vegas_modes(self) -> list:
-        """Return list of modes users can configure."""
-        return [VegasDisplayMode.SCROLL, VegasDisplayMode.FIXED_SEGMENT]
-
-    def get_vegas_content(self):
-        """Return PIL Image(s) for the scroll."""
-        return [self._render_game(g) for g in self.games]
-
-    def get_vegas_segment_width(self) -> int:
-        """For FIXED_SEGMENT: width in panels (optional)."""
-        return 2  # Use 2 panels width
-```
-
-## Display Modes Explained
-
-### SCROLL Mode
-
-Content scrolls continuously within the Vegas stream. Best for plugins with multiple items.
-
-```python
-def get_vegas_display_mode(self):
-    return VegasDisplayMode.SCROLL
-
-def get_vegas_content(self):
-    # Return list of images - each scrolls individually
-    images = []
-    for game in self.games:
-        img = Image.new('RGB', (200, 32))
-        # ... render game info ...
-        images.append(img)
-    return images
-```
-
-**When to use:**
-- Sports scores with multiple games
-- Stock/odds tickers with multiple items
-- News feeds with multiple headlines
-
-### FIXED_SEGMENT Mode
-
-Content is rendered as a fixed-width block that scrolls by with other content.
-
-```python
-def get_vegas_display_mode(self):
-    return VegasDisplayMode.FIXED_SEGMENT
-
-def get_vegas_content(self):
-    # Return single image at your preferred width
-    img = Image.new('RGB', (128, 32))  # 2 panels wide
-    # ... render clock/weather/etc ...
-    return img
-
-def get_vegas_segment_width(self):
-    # Optional: specify width in panels
-    return 2
-```
-
-**When to use:**
-- Clock display
-- Current weather/temperature
-- System status indicators
-- Any "at a glance" information
-
-### STATIC Mode
-
-Scroll pauses completely, your plugin displays using its normal `display()` method for its configured duration, then scroll resumes.
-
-```python
-def get_vegas_display_mode(self):
-    return VegasDisplayMode.STATIC
-
-def get_display_duration(self):
-    # How long to pause and show this plugin
-    return 10.0  # 10 seconds
-```
-
-**When to use:**
-- Important alerts that need attention
-- Detailed information that's hard to read while scrolling
-- Interactive or animated content
-- Content that requires the full display
-
-## User Configuration
-
-Users can override the default display mode per-plugin in their config:
-
-```json
-{
-  "my_plugin": {
-    "enabled": true,
-    "vegas_mode": "static",       // Override: "scroll", "fixed", or "static"
-    "vegas_panel_count": 2,       // Width in panels for fixed mode
-    "display_duration": 10        // Duration for static mode
-  }
-}
-```
-
-The `get_vegas_display_mode()` method checks config first, then falls back to your implementation.
-
-## Content Rendering Guidelines
-
-### Image Dimensions
-
-- **Height**: Must match display height (typically 32 pixels)
-- **Width**:
-  - SCROLL: Any width, content will scroll
-  - FIXED_SEGMENT: `panels × single_panel_width` (e.g., 2 × 64 = 128px)
-
-### Color Mode
-
-Always use RGB mode for images:
-
-```python
-img = Image.new('RGB', (width, 32), color=(0, 0, 0))
-```
-
-### Performance Tips
-
-1. **Cache rendered images** - Don't re-render on every call
-2. **Pre-render on update()** - Render images when data changes, not when Vegas requests them
-3. **Keep images small** - Memory adds up with multiple plugins
-
-```python
-class MyPlugin(BasePlugin):
-    def __init__(self, ...):
-        super().__init__(...)
-        self._cached_vegas_images = None
-        self._cache_valid = False
-
-    def update(self):
-        # Fetch new data
-        self.data = self._fetch_data()
-        # Invalidate cache so next Vegas request re-renders
-        self._cache_valid = False
-
-    def get_vegas_content(self):
-        if not self._cache_valid:
-            self._cached_vegas_images = self._render_all_items()
-            self._cache_valid = True
-        return self._cached_vegas_images
-```
-
-## Fallback Behavior
-
-If your plugin doesn't implement `get_vegas_content()`, Vegas mode will:
-
-1. Create a temporary canvas matching display dimensions
-2. Call your `display()` method
-3. Capture the resulting image
-4. Use that image in the scroll
-
-This works but is less efficient than providing native Vegas content.
-
-## Excluding from Vegas Mode
-
-To exclude your plugin from Vegas scroll entirely:
-
-```python
-def get_vegas_content_type(self):
-    return 'none'
-```
-
-Or users can exclude via config:
-
-```json
-{
-  "display": {
-    "vegas_scroll": {
-      "excluded_plugins": ["my_plugin"]
-    }
-  }
-}
-```
-
-## Complete Example
-
-Here's a complete example of a weather plugin with full Vegas integration:
-
-```python
-from PIL import Image, ImageDraw
-from src.plugin_system.base_plugin import BasePlugin, VegasDisplayMode
-
-class WeatherPlugin(BasePlugin):
-    def __init__(self, *args, **kwargs):
-        super().__init__(*args, **kwargs)
-        self.temperature = None
-        self.conditions = None
-        self._vegas_image = None
-
-    def update(self):
-        """Fetch weather data."""
-        data = self._fetch_weather_api()
-        self.temperature = data['temp']
-        self.conditions = data['conditions']
-        self._vegas_image = None  # Invalidate cache
-
-    def display(self, force_clear=False):
-        """Standard display for normal rotation."""
-        if force_clear:
-            self.display_manager.clear()
-
-        # Full weather display with details
-        self.display_manager.draw_text(
-            f"{self.temperature}°F",
-            x=10, y=8, color=(255, 255, 255)
-        )
-        self.display_manager.draw_text(
-            self.conditions,
-            x=10, y=20, color=(200, 200, 200)
-        )
-        self.display_manager.update_display()
-
-    # --- Vegas Mode Integration ---
-
-    def get_vegas_content_type(self):
-        """Legacy compatibility."""
-        return 'static'
-
-    def get_vegas_display_mode(self):
-        """Use FIXED_SEGMENT for compact weather display."""
-        # Allow user override via config
-        return super().get_vegas_display_mode()
-
-    def get_supported_vegas_modes(self):
-        """Weather can work as fixed or static."""
-        return [VegasDisplayMode.FIXED_SEGMENT, VegasDisplayMode.STATIC]
-
-    def get_vegas_segment_width(self):
-        """Weather needs 2 panels to show clearly."""
-        return self.config.get('vegas_panel_count', 2)
-
-    def get_vegas_content(self):
-        """Render compact weather for Vegas scroll."""
-        if self._vegas_image is not None:
-            return self._vegas_image
-
-        # Create compact display (2 panels = 128px typical)
-        panel_width = 64  # From display.hardware.cols
-        panels = self.get_vegas_segment_width() or 2
-        width = panel_width * panels
-        height = 32
-
-        img = Image.new('RGB', (width, height), color=(0, 0, 40))
-        draw = ImageDraw.Draw(img)
-
-        # Draw compact weather
-        temp_text = f"{self.temperature}°"
-        draw.text((10, 8), temp_text, fill=(255, 255, 255))
-        draw.text((60, 8), self.conditions[:10], fill=(200, 200, 200))
-
-        self._vegas_image = img
-        return img
-```
-
-## API Reference
-
-### VegasDisplayMode Enum
-
-```python
-from src.plugin_system.base_plugin import VegasDisplayMode
-
-VegasDisplayMode.SCROLL        # "scroll" - continuous scrolling
-VegasDisplayMode.FIXED_SEGMENT # "fixed" - fixed block in scroll
-VegasDisplayMode.STATIC        # "static" - pause scroll to display
-```
-
-### BasePlugin Vegas Methods
-
-| Method | Returns | Description |
-|--------|---------|-------------|
-| `get_vegas_content()` | `Image` or `List[Image]` or `None` | Content for Vegas scroll |
-| `get_vegas_content_type()` | `str` | Legacy: 'multi', 'static', or 'none' |
-| `get_vegas_display_mode()` | `VegasDisplayMode` | How plugin behaves in Vegas |
-| `get_supported_vegas_modes()` | `List[VegasDisplayMode]` | Modes available for user config |
-| `get_vegas_segment_width()` | `int` or `None` | Width in panels for FIXED_SEGMENT |
-
-### Configuration Options
-
-**Per-plugin config:**
-```json
-{
-  "plugin_id": {
-    "vegas_mode": "scroll|fixed|static",
-    "vegas_panel_count": 2,
-    "display_duration": 15
-  }
-}
-```
-
-**Global Vegas config:**
-```json
-{
-  "display": {
-    "vegas_scroll": {
-      "enabled": true,
-      "scroll_speed": 50,
-      "separator_width": 32,
-      "plugin_order": ["clock", "weather", "sports"],
-      "excluded_plugins": ["debug_plugin"],
-      "target_fps": 125,
-      "buffer_ahead": 2
-    }
-  }
-}
-```
-
-## Troubleshooting
-
-### Plugin not appearing in Vegas scroll
-
-1. Check `get_vegas_content_type()` doesn't return `'none'`
-2. Verify plugin is not in `excluded_plugins` list
-3. Ensure plugin is enabled
-
-### Content looks wrong in scroll
-
-1. Verify image height matches display height (32px typical)
-2. Check image mode is 'RGB'
-3. Test with `get_vegas_content()` returning a simple test image
-
-### STATIC mode not pausing
-
-1. Verify `get_vegas_display_mode()` returns `VegasDisplayMode.STATIC`
-2. Check user hasn't overridden with `vegas_mode` in config
-3. Ensure `display()` method works correctly
-
-### Performance issues
-
-1. Implement image caching in `get_vegas_content()`
-2. Pre-render images in `update()` instead of on-demand
-3. Reduce image dimensions if possible

-# Weather Plugin Troubleshooting Guide
-
-## Quick Diagnosis
-
-Run the troubleshooting script on your Pi:
-
-```bash
-./troubleshoot_weather.sh
-```
-
-This will check:
-- Plugin installation
-- Configuration files
-- API key setup
-- Network connectivity
-- Cache status
-
-## Common Issues
-
-### 1. "No Weather Data" Message
-
-This appears when the weather plugin cannot fetch or access weather data.
-
-### 2. Missing or Invalid API Key
-
-**Symptoms:**
-- Plugin shows "No Weather Data"
-- Logs show "No valid OpenWeatherMap API key configured"
-- Plugin initialized but no data updates
-
-**Solution:**
-
-1. Get an API key from [OpenWeatherMap](https://openweathermap.org/api)
-   - Sign up for a free account
-   - Navigate to API Keys section
-   - Generate a new API key
-
-2. Add API key to `config/config_secrets.json` (recommended):
-   ```json
-   {
-     "ledmatrix-weather": {
-       "api_key": "your_actual_api_key_here"
-     }
-   }
-   ```
-
-   OR add directly to `config/config.json`:
-   ```json
-   {
-     "ledmatrix-weather": {
-       "enabled": true,
-       "api_key": "your_actual_api_key_here",
-       "location_city": "Dallas",
-       "location_state": "Texas",
-       "location_country": "US"
-     }
-   }
-   ```
-
-3. Restart the LEDMatrix service:
-   ```bash
-   sudo systemctl restart ledmatrix
-   ```
-
-### 3. Plugin Not Enabled
-
-**Symptoms:**
-- Plugin doesn't appear in display rotation
-- No weather data displayed
-
-**Solution:**
-
-Check `config/config.json` and ensure the plugin is enabled:
-
-```json
-{
-  "ledmatrix-weather": {
-    "enabled": true,
-    "display_duration": 30,
-    ...
-  }
-}
-```
-
-### 4. Network/API Connectivity Issues
-
-**Symptoms:**
-- Plugin shows "No Weather Data"
-- Logs show connection errors or timeouts
-
-**Solution:**
-
-1. Check internet connectivity:
-   ```bash
-   ping -c 4 api.openweathermap.org
-   ```
-
-2. Check firewall settings (if applicable)
-
-3. Verify DNS resolution:
-   ```bash
-   nslookup api.openweathermap.org
-   ```
-
-4. Test API directly:
-   ```bash
-   curl "https://api.openweathermap.org/data/2.5/weather?q=Dallas,TX,US&appid=YOUR_API_KEY&units=imperial"
-   ```
-
-### 5. API Rate Limits Exceeded
-
-**Symptoms:**
-- Plugin worked before but now shows "No Weather Data"
-- Logs show HTTP 429 errors
-
-**Solution:**
-
-OpenWeatherMap free tier limits:
-- 1,000 API calls per day
-- 60 calls per minute
-
-Default plugin settings use ~48 calls/day (1800s = 30 min intervals).
-
-If exceeded:
-- Wait for quota reset (daily)
-- Increase `update_interval` in config (minimum 300s = 5 minutes)
-- Upgrade OpenWeatherMap plan
-
-### 6. Invalid Location Configuration
-
-**Symptoms:**
-- Plugin shows "No Weather Data"
-- Logs show geocoding errors
-
-**Solution:**
-
-Ensure location is correctly configured in `config/config.json`:
-
-```json
-{
-  "ledmatrix-weather": {
-    "location_city": "Dallas",
-    "location_state": "Texas",
-    "location_country": "US"
-  }
-}
-```
-
-- Use proper city names
-- Include state for US cities to avoid ambiguity
-- Use ISO 3166-1 alpha-2 country codes (US, GB, CA, etc.)
-
-### 7. Stale Cache Data
-
-**Symptoms:**
-- Weather data not updating
-- Old data displayed
-
-**Solution:**
-
-Clear the cache:
-
-```bash
-# Find cache files
-find cache/ -name "*weather*" -type f
-
-# Remove cache files (plugin will fetch fresh data)
-rm cache/*weather*
-```
-
-### 8. Plugin Not Loading
-
-**Symptoms:**
-- Weather modes don't appear in available modes
-- Logs show plugin loading errors
-
-**Solution:**
-
-1. Check plugin directory exists:
-   ```bash
-   ls -la plugins/ledmatrix-weather/
-   ```
-
-2. Verify manifest.json is valid:
-   ```bash
-   python3 -m json.tool plugins/ledmatrix-weather/manifest.json
-   ```
-
-3. Check logs for specific errors:
-   ```bash
-   sudo journalctl -u ledmatrix -f | grep -i weather
-   ```
-
-4. Verify plugin dependencies are installed:
-   ```bash
-   pip3 install -r plugins/ledmatrix-weather/requirements.txt
-   ```
-
-## Checking Logs
-
-View real-time logs:
-
-```bash
-sudo journalctl -u ledmatrix -f
-```
-
-Filter for weather-related messages:
-
-```bash
-sudo journalctl -u ledmatrix -f | grep -i weather
-```
-
-View last 100 lines:
-
-```bash
-sudo journalctl -u ledmatrix -n 100 | grep -i weather
-```
-
-## Configuration Example
-
-Complete configuration in `config/config.json`:
-
-```json
-{
-  "ledmatrix-weather": {
-    "enabled": true,
-    "display_duration": 30,
-    "location_city": "Dallas",
-    "location_state": "Texas",
-    "location_country": "US",
-    "units": "imperial",
-    "update_interval": 1800,
-    "show_current_weather": true,
-    "show_hourly_forecast": true,
-    "show_daily_forecast": true,
-    "transition": {
-      "type": "redraw",
-      "speed": 2,
-      "enabled": true
-    }
-  }
-}
-```
-
-And in `config/config_secrets.json`:
-
-```json
-{
-  "ledmatrix-weather": {
-    "api_key": "your_openweathermap_api_key_here"
-  }
-}
-```
-
-## Plugin Configuration Schema
-
-The plugin expects configuration under either:
-- `ledmatrix-weather` (plugin ID from manifest)
-- `weather` (legacy/deprecated)
-
-The system checks both when loading configuration.
-
-## Testing the Plugin
-
-1. Enable the plugin in config
-2. Restart the service: `sudo systemctl restart ledmatrix`
-3. Check logs: `sudo journalctl -u ledmatrix -f`
-4. Wait for update interval (default 30 minutes) or force update
-5. Check if weather modes appear in display rotation
-
-## Still Having Issues?
-
-1. Run the troubleshooting script: `./troubleshoot_weather.sh`
-2. Check service status: `sudo systemctl status ledmatrix`
-3. Review logs for specific error messages
-4. Verify all configuration files are valid JSON
-5. Ensure file permissions are correct:
-   ```bash
-   ls -la config/config.json config/config_secrets.json
-   ```
-
-## API Key Security
-
-**Recommended:** Store API key in `config/config_secrets.json` with restricted permissions:
-
-```bash
-chmod 640 config/config_secrets.json
-```
-
-This file is not tracked by git (should be in .gitignore).
-
-## Plugin ID Note
-
-The weather plugin ID is `ledmatrix-weather` (from manifest.json). Configuration should use this ID, though the system also checks for `weather` for backward compatibility.

-# Web Interface Troubleshooting Guide
-
-## Quick Diagnosis Steps
-
-Since the web interface doesn't seem to run and shows no logging after reorganization, follow these steps **on your Raspberry Pi** to diagnose the issue:
-
-### 1. Check Service Status
-
-```bash
-# Check if the web service is running
-sudo systemctl status ledmatrix-web
-
-# Check if it's enabled to start on boot
-sudo systemctl is-enabled ledmatrix-web
-```
-
-### 2. View Service Logs
-
-The service logs to **syslog**, not stdout. Use these commands to view logs:
-
-```bash
-# View recent web interface logs
-sudo journalctl -u ledmatrix-web -n 50 --no-pager
-
-# Follow logs in real-time
-sudo journalctl -u ledmatrix-web -f
-
-# View logs since last boot
-sudo journalctl -u ledmatrix-web -b
-```
-
-### 3. Check Configuration
-
-```bash
-# Check if web_display_autostart is enabled in config
-cat ~/LEDMatrix/config/config.json | grep web_display_autostart
-
-# Should show: "web_display_autostart": true
-```
-
-If it shows `false` or is missing, the web interface won't start (by design).
-
-### 4. Test Manual Startup
-
-Try starting the web interface manually to see error messages:
-
-```bash
-cd ~/LEDMatrix
-python3 web_interface/start.py
-```
-
-This will show any import errors or startup issues directly in the terminal.
-
-## Common Issues and Solutions
-
-### Issue 1: Service Not Running
-
-**Symptom:** `systemctl status ledmatrix-web` shows "inactive (dead)"
-
-**Solutions:**
-```bash
-# Start the service
-sudo systemctl start ledmatrix-web
-
-# Enable it to start on boot
-sudo systemctl enable ledmatrix-web
-
-# Check status again
-sudo systemctl status ledmatrix-web
-```
-
-### Issue 2: web_display_autostart is False
-
-**Symptom:** Service starts but immediately exits gracefully
-
-**Solution:**
-```bash
-# Edit config.json
-nano ~/LEDMatrix/config/config.json
-
-# Set web_display_autostart to true:
-"web_display_autostart": true
-
-# Restart the service
-sudo systemctl restart ledmatrix-web
-```
-
-### Issue 3: Import Errors
-
-**Symptom:** Service fails immediately with import errors in logs
-
-**Possible causes:**
-- Missing dependencies
-- Python path issues
-- Circular import problems
-
-**Solutions:**
-
-```bash
-# Install/reinstall web dependencies
-cd ~/LEDMatrix
-pip3 install --break-system-packages -r web_interface/requirements.txt
-
-# Check for Python errors
-python3 -c "from web_interface.app import app; print('OK')"
-```
-
-### Issue 4: Port Already in Use
-
-**Symptom:** Error message about port 5000 being in use
-
-**Solution:**
-```bash
-# Check what's using port 5000
-sudo lsof -i :5000
-
-# Kill the process if needed
-sudo kill -9 <PID>
-
-# Or change the port in web_interface/start.py
-```
-
-### Issue 5: Permission Issues
-
-**Symptom:** Permission denied errors in logs
-
-**Solution:**
-```bash
-# Ensure proper ownership
-cd ~/LEDMatrix
-sudo chown -R ledpi:ledpi .
-
-# Restart service
-sudo systemctl restart ledmatrix-web
-```
-
-### Issue 6: Flask/Blueprint Import Errors
-
-**Symptom:** ImportError or ModuleNotFoundError in logs
-
-**Check these files exist:**
-```bash
-ls -la ~/LEDMatrix/web_interface/app.py
-ls -la ~/LEDMatrix/web_interface/start.py
-ls -la ~/LEDMatrix/web_interface/blueprints/api_v3.py
-ls -la ~/LEDMatrix/web_interface/blueprints/pages_v3.py
-```
-
-If any are missing, you may need to restore from git or the reorganization.
-
-## Detailed Logging Commands
-
-### View All Web Service Logs
-```bash
-# Show all logs with timestamps
-sudo journalctl -u ledmatrix-web --no-pager
-
-# Show logs from the last hour
-sudo journalctl -u ledmatrix-web --since "1 hour ago"
-
-# Show logs between specific times
-sudo journalctl -u ledmatrix-web --since "2024-10-14 10:00:00" --until "2024-10-14 11:00:00"
-
-# Show only errors
-sudo journalctl -u ledmatrix-web -p err
-```
-
-### Check Python Import Issues
-```bash
-cd ~/LEDMatrix
-
-# Test imports step by step
-python3 -c "import sys; sys.path.insert(0, '.'); from src.config_manager import ConfigManager; print('ConfigManager OK')"
-
-python3 -c "import sys; sys.path.insert(0, '.'); from src.plugin_system.plugin_manager import PluginManager; print('PluginManager OK')"
-
-python3 -c "import sys; sys.path.insert(0, '.'); from web_interface.app import app; print('Flask App OK')"
-```
-
-## Service File Check
-
-Verify the service file is correct:
-
-```bash
-cat /etc/systemd/system/ledmatrix-web.service
-```
-
-Should contain:
-```
-[Unit]
-Description=LED Matrix Web Interface Service
-After=network.target
-
-[Service]
-Type=simple
-User=root
-WorkingDirectory=/home/ledpi/LEDMatrix
-Environment=USE_THREADING=1
-ExecStart=/usr/bin/python3 /home/ledpi/LEDMatrix/start_web_conditionally.py
-Restart=on-failure
-RestartSec=10
-StandardOutput=syslog
-StandardError=syslog
-SyslogIdentifier=ledmatrix-web
-
-[Install]
-WantedBy=multi-user.target
-```
-
-If it's different or points to old paths, reinstall it:
-
-```bash
-cd ~/LEDMatrix
-sudo bash install_web_service.sh
-sudo systemctl daemon-reload
-sudo systemctl restart ledmatrix-web
-```
-
-## Post-Reorganization Checklist
-
-Verify the reorganization completed correctly:
-
-```bash
-cd ~/LEDMatrix
-
-# These files should exist in new locations:
-ls web_interface/app.py
-ls web_interface/start.py
-ls web_interface/requirements.txt
-ls web_interface/blueprints/api_v3.py
-ls web_interface/blueprints/pages_v3.py
-
-# start_web_conditionally.py should point to new location
-grep "web_interface/start.py" start_web_conditionally.py
-```
-
-## Emergency Recovery
-
-If nothing works, you can rollback to the old structure:
-
-```bash
-cd ~/LEDMatrix
-
-# Check git status
-git status
-
-# If changes aren't committed, revert
-git checkout .
-
-# Or restore specific files from old_web_interface
-# (if that directory exists)
-```
-
-## Recommended Diagnostic Sequence
-
-Run these commands in order to get a complete picture:
-
-```bash
-#!/bin/bash
-echo "=== Web Interface Diagnostic Report ==="
-echo ""
-echo "1. Service Status:"
-sudo systemctl status ledmatrix-web
-echo ""
-echo "2. Config Autostart Setting:"
-cat ~/LEDMatrix/config/config.json | grep web_display_autostart
-echo ""
-echo "3. Recent Logs (last 20 lines):"
-sudo journalctl -u ledmatrix-web -n 20 --no-pager
-echo ""
-echo "4. File Structure Check:"
-ls -la ~/LEDMatrix/web_interface/
-echo ""
-echo "5. Python Import Test:"
-cd ~/LEDMatrix
-python3 -c "from web_interface.app import app; print('✓ Flask app imports successfully')" 2>&1
-echo ""
-echo "=== End of Diagnostic Report ==="
-```
-
-Save this as `diagnose_web.sh`, make it executable, and run it:
-
-```bash
-chmod +x diagnose_web.sh
-./diagnose_web.sh
-```
-
-## Success Indicators

-    limit=50,
-    plugin_id="plugin-id"
-)
-```
-
-## Integration Notes
-
-### Backward Compatibility
-
-All changes maintain backward compatibility:
-- Existing API endpoints continue to work
-- Old code can gradually migrate to new infrastructure
-- Feature flags can be added for gradual rollout
-
-### Migration Path
-
-1. **Phase 1** infrastructure is ready to use but not yet integrated into all endpoints
-2. **Phase 2** state management can be integrated incrementally
-3. **Phase 3** frontend modules are available but original file still works
-4. **Phase 4** testing and logging can be enabled gradually
-
-### Next Steps
-
-1. Integrate atomic config saves into existing save endpoints
-2. Integrate operation queue into plugin install/update/uninstall endpoints
-3. Use structured errors in all API endpoints
-4. Integrate state manager with plugin manager
-5. Migrate frontend code to use new modules
-6. Add integration tests for critical flows
-7. Enable structured logging in production
-
-## Benefits
-
-1. **Reliability**: Atomic saves prevent config corruption, operation queue prevents conflicts
-2. **Debuggability**: Structured errors and logging provide clear context
-3. **Maintainability**: Modular code is easier to understand and modify
-4. **Consistency**: Standardized APIs and error handling
-5. **Observability**: Health monitoring and operation history provide visibility
-
-## Testing
-
-Run tests with:
-```bash
-python -m pytest test/web_interface/
-```
-
