ChuckandClaude Opus 5.5 a231d4dbc7 chore: delete unreferenced scripts and archived docs; fix stale doc claims (#607) 
* chore(scripts): delete unreferenced helper scripts

None of these is referenced by an installer, systemd unit, CI workflow,
test, the web UI or src/:

- utils/cleanup_venv.sh removes venv_web_v2, which nothing creates
- utils/clear_python_cache.sh hardcodes ~/LEDMatrix and a .webassets-cache
  nothing uses
- install/migrate_config.sh only copies the template, which the installer
  and ConfigManager already do
- install/debug_install.sh, debug/debug_web_manual.py
- diagnose_web_ui.sh and verify_web_ui.sh overlap diagnose_web_interface.sh,
  which the docs point to
- fix_internet_connectivity.sh is iptables-only (stale on nftables)
- diagnose_plugin_permissions.sh, dev/validate_python.py
- download_nba_logos.py + README_NBA_LOGOS.md: logo_downloader fetches
  logos on demand
- setup_plugin_repos.py linked into the production plugin-repos/ dir; the
  dev workflow is scripts/dev/dev_plugin_setup.sh, and
  MULTI_ROOT_WORKSPACE_SETUP.md now uses it

* chore(config): drop unused plugin_system flags and a dead unit comment

- config.template.json: remove plugin_system.auto_discover,
  auto_load_enabled and development_mode. Nothing reads them; the web UI
  only stores them when a client sends them. ConfigManager's migration
  only adds template keys, so existing configs keep theirs unchanged.
- config.template.json: re-indent vegas_scroll's live_* keys.
- systemd/ledmatrix.service: remove the comment documenting
  LEDMATRIX_ON_DEMAND_PLUGIN / on_demand_env.conf; nothing reads either.
- CONFIG_REFERENCE.md: say the legacy keys are no longer in the template.

* docs: delete docs/archive and PLUGIN_IMPLEMENTATION_SUMMARY.md

- docs/archive/: superseded guides; the repository history keeps them
  and no live doc links into the directory. The one open document in it,
  WEB_UI_AUDIT_2026-09.md, moves to docs/audits/ and is linked from the
  docs index.
- PLUGIN_IMPLEMENTATION_SUMMARY.md invented usage statistics, called
  v2.0.0 current, listed shipped auto-updates as future work and
  documented a BasePlugin.get_config() that does not exist.
- docs/README.md: drop both, and stop telling contributors to archive
  obsolete pages instead of deleting them.

* docs(plugin-api): fix extra_small_font size, cache metric key and scroll pacing example

- PLUGIN_API_REFERENCE: extra_small_font loads at 7, not 6 (crisp_size
  snaps it, src/display_manager.py); get_cache_metrics() returns
  cache_hit_rate, not hit_rate (src/cache/cache_metrics.py).
- ADVANCED_PLUGIN_DEVELOPMENT: the basic scrolling example slept in a loop
  and never passed frame_hold; use ScrollHelper + scroll_config.configure()
  and set_scrolling_state(True, frame_hold=...) as PLUGIN_API_REFERENCE does.

* docs(plugin-config): match the config tab, icon and web-action docs to the code

- PLUGIN_CONFIG_QUICK_START / PLUGIN_CONFIGURATION_TABS /
  PLUGIN_CONFIGURATION_GUIDE: there is no "Reset to Defaults" button (the
  tab has Refresh, Update, Uninstall, Save Configuration); plugin config
  hot-reloads (ConfigService + on_config_change), so no restart; the
  schema is found by the fixed name config_schema.json, not a manifest
  config_schema field; the tab row is "Plugin Manager", not "Plugins";
  forms are server-rendered from /v3/partials/plugin-config/<id>; the
  duration hook is get_display_duration()/display_duration; a class_name
  mismatch raises PluginError; the store requires id, name, class_name and
  display_modes (not version); plugin_system.debug/log_level do not exist
  (use run.py -d / LEDMATRIX_DEBUG). Drop "future" features that shipped.
- PLUGIN_CONFIG_CORE_PROPERTIES: list all of CORE_PLUGIN_PROPERTIES,
  including skin, skin_options and the vegas_* tuning keys.
- PLUGIN_CUSTOM_ICONS: icon is only a Font Awesome class (fallback
  fa-puzzle-piece); emoji/URL icons and getPluginIcon() never existed in
  v3. Note that /api/v3/plugins/installed currently omits icon.
- PLUGIN_WEB_UI_ACTIONS (+ example JSON): success_message, error_message
  and step1_message are never read.

* docs(store): describe the monorepo registry and the store UI as they are

- PLUGIN_STORE_GUIDE: the Plugin Store is a section of the Plugin
  Manager tab; URL installs are "Install from GitHub" -> "Install Single
  Plugin"; bulk update exists (Check & Update All) plus opt-in weekly
  auto-update; PluginStoreManager() defaults to plugins/, so the Python
  examples pass plugin-repos; registry plugins are downloaded (GitHub API,
  ZIP fallback), not cloned; updates compare version with latest_version.
- PLUGIN_REGISTRY_SETUP_GUIDE: replace the per-plugin-repo + tag
  walkthrough with a short page on the monorepo registry (plugin_path,
  latest_version, update_registry.py) that points at the monorepo's own
  SUBMISSION.md. Drops the reference to the deleted
  PLUGIN_IMPLEMENTATION_SUMMARY.md and setup_plugin_repos.py.
- plugin_registry_template.json: use the real entry shape.
- PLUGIN_QUICK_REFERENCE: automatic background updates exist (opt-in);
  registry example and publishing steps use the monorepo, not tags.
- PLUGIN_DEVELOPMENT_GUIDE: tags/releases are not read by the store.

* docs(readme): fix the Triple Bonnet mapping, install prerequisites and backup names

- README: the Adafruit Triple Bonnet uses `regular` (3 outputs), not
  `regular-pi1` (1 output) -- src/matrix_support.py MAPPING_OUTPUTS, and
  the README's own hardware_mapping section; the template default mapping
  is adafruit-hat, the PWM mod switches it to adafruit-hat-pwm; manual
  install only needs git up front (first_time_install.sh installs
  python-dev-is-python3, cmake, ninja-build etc.; cython3/scons are not
  used); the Pi Zero 2 W is a supported low-memory board, consistent with
  PRODUCT.md, LOW_MEMORY_BOARDS.md and the installer's low-memory build;
  fix the "First_time_install.sh" spelling, an orphan "2." list item and
  the hello-world starter link (it lives in the plugins monorepo).
- CONFIG_DEBUGGING: automatic backups are
  config/backups/config.json.backup.<YYYYMMDD_HHMMSS_ffffff> (five kept),
  not config_YYYYMMDD_HHMMSS.json.

* docs(dev): correct the test-running and rgbmatrix build instructions

- HOW_TO_RUN_TESTS: coverage is not collected by a plain pytest run and
  pytest.ini has no threshold; the only one is --cov-fail-under=52 in the
  core unit-test job of .github/workflows/test.yml, which runs the whole
  test/ tree (not an allowlist). Almost no tests carry markers, so
  -m integration / -m slow select nothing; drop them and -m unit as the
  quick check. Replace the hardcoded /home/chuck path.
- DEVELOPMENT: the rgbmatrix package is built with pip install . from
  the submodule root (scikit-build-core + CMake + Ninja), as
  first_time_install.sh does; there is no make build-python /
  bindings/python step, and the build deps are python-dev-is-python3,
  cmake and ninja-build, not cython3/scons.

* docs(wifi): the setup AP is open; auto-enable can be turned off without code changes

- WIFI_NETWORK_SETUP / SSH_UNAVAILABLE_AFTER_INSTALL: both AP paths in
  src/wifi_manager.py create an open network and nothing reads
  ap_password, so drop the "ledmatrix123" password and the ap_password
  key/advice.
- SSH_UNAVAILABLE_AFTER_INSTALL: disabling automatic AP mode does not
  need code changes -- auto_enable_ap_mode is a WiFi-tab toggle and
  POST /api/v3/wifi/ap/auto-enable; note the monitor daemon reads
  wifi_config.json at start, so restart it after changing the setting.
  Use the ledpi username and a relative install path like the other docs.

* docs(reference): add auto_update, drop drifted line numbers, fix UI and service details

- CONFIG_REFERENCE: document the top-level auto_update.enabled key (read
  by web_interface/auto_update.py and src/auto_update_setup.py); replace
  drifted file:line references with function names; the template's
  dim_schedule mode is "global".
- ADVANCED_FEATURES: core does not read a per-plugin background_service
  block (the sports plugins read their own), and priority is "higher
  number = higher priority" on FetchRequest but not used for ordering.
- WEB_INTERFACE_GUIDE: the General tab toggle is "Web Display Autostart"
  (web interface service), brightness is 1-100, and config paths are
  relative to the LEDMatrix folder, not /config.

* docs: drop references to code removed in #608

get_installed_plugin_info, WiFiManager's saved_networks and the six
always-skipping plugin test files are deleted there. NetworkManager already
remembers joined networks; LEDMatrix no longer stores WiFi passwords.

* docs: don't link SKIN_SYSTEM.md from the core-properties page

#615 deletes SKIN_SYSTEM.md; with this link, whichever of the two merged
second would break test_doc_links. The skin/skin_options entries go when
#615 removes the keys.

Migration Guide

This guide helps you migrate from older versions of LEDMatrix to the latest version.

Breaking Changes

Script Path Reorganization

Scripts have been reorganized into subdirectories for better organization. If you have automation, cron jobs, or custom tooling that references old script paths, you must update them.

Installation Scripts

All installation scripts have been moved from the project root to scripts/install/:

Old Path New Path
install_service.sh scripts/install/install_service.sh
install_web_service.sh scripts/install/install_web_service.sh
install_wifi_monitor.sh scripts/install/install_wifi_monitor.sh
setup_cache.sh scripts/install/setup_cache.sh
configure_web_sudo.sh scripts/install/configure_web_sudo.sh

Permission Fix Scripts

All permission fix scripts have been moved to scripts/fix_perms/:

Old Path New Path
fix_assets_permissions.sh scripts/fix_perms/fix_assets_permissions.sh
fix_cache_permissions.sh scripts/fix_perms/fix_cache_permissions.sh
fix_plugin_permissions.sh scripts/fix_perms/fix_plugin_permissions.sh
fix_web_permissions.sh scripts/fix_perms/fix_web_permissions.sh

Action Required

  1. Update cron jobs: If you have any cron jobs that call these scripts, update the paths.
  2. Update automation scripts: Any custom scripts or automation that references the old paths must be updated.
  3. Update documentation: Update any internal documentation or runbooks that reference these scripts.

Example Updates

Before:

# Old cron job or script
0 2 * * * /path/to/LEDMatrix/fix_cache_permissions.sh
sudo ./install_service.sh

After:

# Updated paths
0 2 * * * /path/to/LEDMatrix/scripts/fix_perms/fix_cache_permissions.sh
sudo ./scripts/install/install_service.sh

Verification

After updating your scripts, verify they still work:

# Check the installation scripts are at their new paths
ls scripts/install/*.sh
./scripts/install/install_service.sh --help   # prints usage only
# Note: running install_service.sh for real (with sudo, no --help)
# reinstalls, enables and restarts ledmatrix.service, ledmatrix-web.service
# and the update-verify units.

# Test permission scripts
ls scripts/fix_perms/*.sh
sudo ./scripts/fix_perms/fix_cache_permissions.sh

Other Changes

Configuration File Location

No changes to configuration file locations. The configuration system remains backward compatible.

Plugin System

The plugin system has been enhanced but remains backward compatible with existing plugins.

Getting Help

If you encounter issues during migration:

  1. Check the project root README for current installation and usage instructions
  2. Review script README files:
  3. Check system logs: journalctl -u ledmatrix -f or journalctl -u ledmatrix-web -f
  4. Review the troubleshooting section in the main README
