 ## Unreleased
 
+## 3.9.0
+
+Per-plugin schedules (#799), the end of the cache-key mailboxes (#773,
+**breaking**: see "Removed" below; restart the display and the web interface
+together after updating), a Vegas pause fix (#798), and a fix for Update Code
+failing with `.git/index.lock: File exists` on a slow Pi (#801, #802).
+
+### Fixed: Update Code left `.git/index.lock` behind
+
+A git that Python's timeout killed could not remove `.git/index.lock`, so
+every later update failed with "Unable to create '.../.git/index.lock': File
+exists", and removing the file by hand only lasted until the next timeout.
+Update Code now runs git in its own process group, stops it with SIGTERM
+before SIGKILL and clears the lock it left; pulls get 600 s instead of 60 s;
+the read-only version and status checks set `GIT_OPTIONAL_LOCKS=0` so a
+timed-out poll cannot take the lock. A rebase in progress (detached HEAD) now
+stops Update Code with a message instead of failing inside git; an abandoned
+one is quit first. If a device is already stuck on an older release, stop
+the services, kill any running git, remove `.git/index.lock` and pull by hand
+once. (#801, #802)
+
+### Added: plugin schedules
+
+Schedule → Plugin Schedules sets when each plugin may show, per day or with
+one time range, and can hide a plugin whenever any game is live ("no news or
+stocks on gameday"). A hidden plugin is skipped in the rotation, the live
+takeover and Vegas mode, but stays loaded. New core config key
+`plugin_schedules`, new `GET/POST /api/v3/config/plugin-schedules`, new
+module `src/plugin_schedule.py` (the display schedule's window rule now
+lives there too).
+
+### Removed: the cache-key mailboxes (control socket stage 5) -- breaking
+
+The control socket (`docs/IPC_CONTROL_SOCKET.md`) is now the only way the
+web interface sends the display a command. The file mailboxes it fell back
+to for one release are gone.
+
+- **`display_on_demand_request` and `plugin_error_clear_request` are no
+  longer written or read.** The display stops polling the on-demand mailbox
+  (`MailboxWatch`, `MAILBOX_POLL_INTERVAL_WITH_SOCKET`,
+  `_consume_on_demand_request` and the persisted
+  `display_on_demand_processed_id` guard are removed), and the error
+  publisher stops reading the clear request. `CacheManager.file_signature`,
+  `src.cache_manager.MailboxWatch`, `src.ipc.client.should_fall_back` and
+  `src.error_aggregator.ERROR_CLEAR_REQUEST_KEY` are removed.
+- **A write to either key is dropped, with one warning per writer.**
+  `CacheManager.save_cache` (and so `set`) refuses `RETIRED_MAILBOX_KEYS`
+  and logs `Ignored a write to the retired '<key>' cache key by plugin
+  '<id>'`, naming the plugin from the call stack or the request. Plugins
+  must use `BasePlugin.request_on_demand()` / `end_on_demand()` (3.8.1).
+  In the official monorepo, birdnet-go, mqtt-notifications, on-air and
+  pomodoro-timer still write the mailbox, but only as their fallback when
+  those methods are missing or answer `None`.
+- **On-demand routes without a listening display.** `POST
+  /api/v3/display/on-demand/start` with no display listening starts the
+  service (when `start_service`, the default) and answers **`202`** with
+  `status: "starting"` at once; a single background worker in the web
+  process (`web_interface/on_demand_dispatch.py`) sends the request until
+  the display acknowledges it, for up to 45 s (10 s for a service that is
+  running but has no socket yet). `GET /display/on-demand/status` reports it
+  (`starting`; still `starting` with `delivered: true` after the display
+  acknowledges it, until the display publishes the state for that
+  `request_id`, now part of its on-demand state, for at most 30 s; then the
+  display's state, or `error` / `start-timeout`), and
+  `/display/current-status` adds `on_demand_pending`. A newer start replaces
+  a pending one and a stop cancels it (`cancelled_request_id`). The web UI
+  and the MQTT bridge treat `202` as taken. With the service stopped and
+  `start_service` false it answers `400`. Every other socket failure (`unknown_command`
+  from an older display, `disabled`/`unsupported`, `busy`, a timeout) is a
+  `503`. `/stop` answers `503` when no display is listening, unless
+  `stop_service` stops the service. `transport` is always `"socket"`; the
+  `"mailbox"` value is gone.
+- **`POST /api/v3/errors/clear` without the socket answers `503`** (with
+  `context.socket_error` and a message saying why) instead of recording a
+  request. `clear_pending` in the error routes is now always `false`;
+  `src.error_aggregator.read_error_report()` returns only the snapshot, and
+  `error_summary_from_report()` / `plugin_health_from_report()` /
+  `request_error_clear()` lose their clear-request arguments.
+- **Kept:** the display still writes `display_current_state`,
+  `display_on_demand_state`, `plugin_runtime_snapshot` and the heartbeat
+  file, because the web interface reads them whenever the socket cannot
+  answer (a stopped or starting display, a web user not yet in the socket's
+  group, Windows), and `display_on_demand_config`, its own record for
+  resuming a session after a restart.
+- **Windows and `LEDMATRIX_CONTROL_SOCKET=off`:** with no socket, the web
+  interface can no longer start or stop on-demand sessions or clear errors
+  on a running display (the mailbox used to carry them).
+
+### Fixes
+
+- Vegas: a `pause` (STATIC) turn redraws its plugin for the whole pause,
+  once a second, or at the high-FPS rate for a plugin that declares
+  `needs_high_fps` (or scrolls) -- the rate the rotation uses. The pause used
+  to call `display()` once and sleep out the duration, so a plugin that
+  rotates its screens or animates was frozen on its first frame. The first
+  draw still passes `force_clear=True`; later ones pass nothing. A redraw
+  that finds the plugin's `update()` holding its lock is skipped; the pause
+  carries on.
+- Update Code no longer fails forever with `fatal: Unable to create
+  '.../.git/index.lock': File exists`. A git killed mid-command (a pull or
+  checkout that hit its timeout is SIGKILLed; a power cut does the same)
+  leaves that lock behind. Update Code and the automatic update's rollback
+  now remove it when no git process is running in the checkout and the
+  file is more than a few seconds old (new `web_interface/git_index_lock.py`);
+  while another git is running, Update Code says so instead of failing.
+
+## 3.8.7
+
+Sports consolidation family 10: `src.common.sports_view_model`, the game
+dict every scoreboard screen draws, which the scoreboards adopt by flooring
+on 3.8.7 (#796).
+
+### New modules
+
+- `src/common/sports_view_model.py` -- sports consolidation family 10, once
+  the plugins made `_extract_game_details_common` (nine bodies) one:
+  `SportsViewModelMixin` (`SportsCore`), the game dict every scoreboard screen
+  draws from one ESPN event, with `_status_is_final`, `_score_text`,
+  `_team_logo_url`, `_extract_team_record` and the `_logo_filename` seam
+  beside it. One rule for a final (state "post", not `completed: false`, not
+  postponed, canceled, suspended, abandoned, delayed or pending; a forfeit is
+  final); a called-off game is never live; scores are integer text; a time
+  without an offset is UTC. Keys are additive only; the module docstring
+  lists every key, its type and default. A plugin may inherit the mixin once
+  it floors on 3.8.7, and deletes its copies then. (#796)
+
+## 3.8.6
+
+A **Start Display on Boot** toggle on the General tab (#792), two fixes to
+the shared rankings code (#791), `get_espn_scoreboard()` no longer caching a
+null-events answer, and sports consolidation family 9:
+`src.common.sports_live_fetch`, which the scoreboards adopt by flooring on
+3.8.6 (#793).
+
+### Features
+
+- General tab: a **Start Display on Boot** toggle turns
+  `ledmatrix.service`'s autostart on or off right away (no Save needed),
+  through the existing `enable_autostart` / `disable_autostart` system
+  actions. It shows systemd's own state, so nothing is stored in
+  `config.json`; the default stays on (the installer enables the unit). The
+  web interface still starts on boot either way. Hidden when the unit's state
+  cannot be read (not installed, or no systemd).
+
+### New modules
+
+- `src/common/sports_live_fetch.py` -- sports consolidation family 9, once the
+  plugins made `_fetch_todays_games` (seven bodies) and `_fetch_odds` (three)
+  one each: `SportsLiveFetchMixin` (`SportsCore`), with the odds worker
+  `_drain_odds_queue` beside them. The live poll asks ESPN on every poll
+  (a copy another reader fetched within the last second is reused) and
+  leaves the answer under the shared `espn_scoreboard_cache_key` for its
+  dates; college basketball is asked by date like every other league; an
+  answer whose `events` is not a list counts as no games. Odds never block
+  `update()`: one daemon worker per manager answers a queue and attaches each
+  line in place under `_games_lock`, one batch in flight at a time. A plugin
+  may inherit the mixin once it floors on 3.8.6, and deletes its copies then.
+  (#793)
+
+### Fixes
+
+- `get_espn_scoreboard()` no longer caches an answer whose `events` is not a
+  list (ESPN has sent `"events": null`): every reader of the shared scoreboard
+  key -- odds-ticker, the other scoreboards -- inherited it until it aged out.
+  The answer is still returned to the caller as it came.
+
+- `SportsRankingsMixin` (#789's deferred review points, now that it is the
+  only copy): a poll entry whose `current` cannot be converted to an
+  integer (`None`, a non-numeric string) is skipped instead of throwing
+  away the whole poll -- which left
+  every team unranked and re-fetched the standings on every update -- and
+  `_ranked_positions()` decides id-or-abbreviation per side, so one side
+  without an id no longer drops the other side's id and lets a shared
+  abbreviation rank the wrong school. Well-formed ESPN data ranks as before.
+
+## 3.8.5
+
+Fewer ESPN requests on the hourly schedule refresh (#754), and sports
+consolidation family 8: `src.common.sports_rankings`, which the scoreboards
+adopt by flooring on 3.8.5 (#789).
+
+### ESPN: settled days are not fetched again
+
+- A scoreboard's hourly Recent/Upcoming refresh asks ESPN for its window one
+  day at a time, and most of those days can no longer change. A chunk whose
+  last day is three or more days back is now kept in memory for 24 hours
+  (compressed, at most 512 entries / 8 MB) and answered from there, for
+  `fetch_espn_scoreboard` and the background service alike. Failed and
+  capped chunks are never kept, and each hit is parsed afresh. Against live
+  ESPN, a second refresh of five scoreboard windows went from 111 requests
+  and 10.2 MB to 50 requests and 3.2 MB with identical events. (#754)
+
+### New modules
+
+- `src/common/sports_rankings.py` -- sports consolidation family 8, once the
+  plugins made `_fetch_team_rankings`, `_choose_poll` (three bodies each),
+  `_load_division_team_ids`, `_passes_other_filters`, `_best_rank` and
+  `_is_ranked_game` (two each) one each: `SportsRankingsMixin` (`SportsCore`),
+  with `_ranked_positions` and `_poll_season_ended` beside them, and
+  `choose_top_division_poll()` for the dynamic team resolvers. Ranks are kept
+  by ESPN team id as well as abbreviation and a game with ids is ranked by id;
+  a poll from a season that has ended (its `endDate` has passed) loads
+  nothing, so no rank badge shows between seasons; the college football
+  division rosters are asked for the season year. A plugin may inherit the
+  mixin once it floors on 3.8.5, and deletes its copies then. (#789)
+
+## 3.8.4
+
+A panel that cannot reach its refresh cap is reported with a cap it can hold
+(#759); a failed on-demand request ends its own session (#779); exception
+messages stay out of API responses (#778); and sports consolidation family 7,
+`src.common.sports_rotation`, which the scoreboards adopt by flooring on
+3.8.4 (#786).
+
+### Scroll speed: a panel slower than its refresh cap is reported
+
+- Scroll speeds are solved against `limit_refresh_rate_hz`, so a panel that
+  cannot reach its cap ran every scroll slow by the shortfall, with no sign
+  why (one Pi 4 on a 120 Hz cap refreshed at ~110 Hz: 60 px/s ran at 55).
+  Once the display has measured the real rate over three windows of
+  scrolling, a panel more than 3% short of the cap is logged once, as a
+  warning from `src.common.frame_timing` that names a cap it can hold (a
+  multiple of 10, 5% under the measurement). The Display tab shows the same
+  under Limit Refresh Rate, with a button that fills it in, from the new
+  `GET /api/v3/config/refresh-rate`. Not checked in the emulator or on the
+  fallback canvas.
+- The frame-stats file records `planned_refresh_hz` (additive), and the
+  scroll-speed advice behind the Vegas slider ignores a measurement written
+  under a different cap. Until now, after the cap changed, the slider kept
+  advising from the old rate until the display restarted.
+- New in `src.common.scroll_config`: `refresh_shortfall()`, `holdable_cap()`
+  and `describe_refresh_shortfall()`.
+
+### Fixes
+
+- Web API error responses no longer carry an exception's message (CodeQL
+  `py/stack-trace-exposure`). `describe_exception()` now returns a reason
+  code -- the exception type, plus the errno for an `OSError`
+  (`OSError:EIO`, `PermissionError:EACCES`) -- and logs the message
+  instead, so `details` still names the fault without quoting paths, URLs
+  or library internals. The display service status and the on-demand
+  start/stop `service` results keep `active`, `returncode` and `started`
+  but drop systemctl's `stdout`/`stderr`; WiFi, unit-refresh and
+  config-save failures say what failed and point at the log.
+
+### New modules
+
+- `src/common/sports_rotation.py` -- sports consolidation family 7, once the
+  plugins made `_by_importance`, `_other_games_window`,
+  `_advance_other_games_if_due` (two bodies each), `_rotate_other_games_on_display`
+  (two) and `_attach_odds_to_rotated_games` (three; ufc had none) one each:
+  `SportsRotationMixin` (`SportsCore`), the other-games rotation. The window
+  advances under `_games_lock`, so `update()` and `display()` advancing it at
+  once no longer skip a window; the display path's due-check reads the pool
+  `_compose_selection` will cut, unfiltered fallback included; rotated-in
+  games get odds when `show_odds` is on. `_rankings_loaded()` is the seam
+  `_by_importance` asks (default: the abbreviation table is non-empty;
+  football also counts its by-id table). A plugin may inherit the mixin once
+  it floors on 3.8.4, and deletes its copies then. (#786)
+
+## 3.8.3
+
+Fresh installs on Raspberry Pi OS Lite work again: 3.8.2's installer reported
+a desktop on Lite and stopped (#780, #781). Also lighter cached ESPN
+scoreboard windows (#749), a Vegas static-pause fix and a store reinstall
+restart prompt (#753), and display modes a plugin computes from its config in
+the web UI (#769).
+
+### Install
+
+- The installer no longer stops Raspberry Pi OS Lite with "Desktop environment
+  detected". Its package check searched whole `dpkg -l` lines, and `.*kde`
+  matched inside `libblockdev` ("bloc**kde**v"), which Lite ships; it now
+  matches installed package names from their start (#780). Desktop
+  metapackages and session managers are matched as whole names, so
+  `gnome-keyring` and similar standalone parts no longer count, and the list
+  now includes Raspberry Pi OS Trixie's `rpd-wayland-core` / `rpd-x-core`
+  (which replaced `raspberrypi-ui-mods`), Debian's `task-*-desktop` and
+  multi-arch names (#781).
+- Only a **running** desktop stops the install: a display manager that
+  `systemctl is-active` reports (`display-manager`, lightdm, gdm, sddm,
+  lxdm), with directions to boot to the console instead. Desktop packages or
+  session files on a Pi that boots to the console print a warning and the
+  install continues (#781).
+
+### Fixed
+
+- A Vegas static pause no longer ends at once for a plugin whose
+  `display_duration` is not a number (a string such as `"20"` or `null` from
+  config.json, as clock-simple, calendar and countdown return it). The pause
+  reads the duration the way the rotation does, with the same fallbacks: 30 s
+  for anything that is not a number, 15 s for zero or less. The helper moved
+  from `display_controller._finite_seconds` to `base_plugin.finite_seconds`,
+  unchanged (#753).
+- Reinstalling an enabled plugin from the store now asks for a restart for
+  plugins that install under their manifest id (Weather as
+  `ledmatrix-weather`, Music, Stocks, Leaderboard): the route checked the
+  enabled flag under the registry id (#753).
+- `/display/modes`, the on-demand dialog and `on-demand/start` by mode see the
+  modes a plugin computes from its config (soccer-scoreboard's custom
+  leagues), which no manifest can list. The display records the modes it
+  registered in the runtime snapshot, and the web catalog prefers them while
+  the plugin is loaded, falling back to the manifest otherwise. No manifest or
+  plugin change needed (#769, fixes #668).
+
+### Performance
+
+- `BackgroundDataService` drops the parts of an ESPN `/scoreboard` response no
+  scoreboard reads (stat leaders, athlete cards, links, headlines, highlights,
+  geo broadcasts) before caching it (`src/common/espn_payload.py`,
+  core-internal). Measured on one Pi (hdpi), the five scoreboard windows went
+  from 10.6 MB to 3.0 MB of JSON and ~40 MB to ~12 MB of parsed objects.
+  `submit_fetch_request(slim_payload=False)` caches a response whole (#749).
+
+### Tooling
+
+- `test/test_sports_helpers.py`'s parity tests pass again with
+  `LEDMATRIX_PLUGINS` set. The scoreboards deleted their copies of the
+  `sports_helpers` bodies and constants when they adopted `SportsHelpersMixin`
+  (ledmatrix-plugins #563/#564), and the 19 tests still expected them. A copy
+  that is gone now counts as adopted when the plugin imports
+  `src.common.sports_helpers`, as the stage 3/4 and game-over parity tests
+  already do; a copy that remains must still match. (#777)
+- `src/common/README.md` lists `espn_payload`, which
+  `test_common_readme_lists_every_module` requires (#782).
+
+### Dead code removed, unused plugin APIs deprecated
+
+An over-engineering audit of the whole tree. Every symbol below was checked
+against core, the plugin monorepo and all eight third-party plugins in
+`plugins.json` before it went. Nothing a plugin imports was removed;
+plugin-facing methods only get `@deprecated` (see below).
+
+- **Deprecated for removal in 3.10.0** (warn once per process, in
+  `journalctl -u ledmatrix`). No plugin in core, the monorepo or the registry
+  calls them. `docs/DEPRECATIONS_3.8.md` is the regenerated scan, which
+  `scripts/plugin_api_usage.py` now runs for these owners too:
+  - `LogoDownloader`: the bulk-download and RGBA-conversion methods
+    (`fetch_teams_data`, `extract_teams_from_data`,
+    `download_missing_logos_for_league`, `download_all_ncaa_football_logos`,
+    `download_all_missing_logos`, `convert_image_to_rgba`,
+    `convert_all_logos_to_rgba`). `download_missing_logo()` stays.
+  - `ConfigManager`: `rollback_config`, `list_backups`,
+    `validate_config_file`, `get_secret`, `cleanup_orphaned_plugin_configs`,
+    `validate_all_plugin_configs`.
+  - `APIHelper`: `fetch_espn_scoreboard`/`_standings`/`_rankings`,
+    `set_cache`, `get_cache`, `set_rate_limit`, `get_request_stats`. `get()`
+    stays.
+  - `BackgroundDataService`: `get_result`, `is_request_complete`,
+    `get_request_status` (pass `callback=` to `submit_fetch_request()`).
+  - `PluginManager`: `get_all_plugins`, `get_plugin_info`,
+    `get_all_plugin_info`, `get_plugin_display_modes`, `find_plugin_for_mode`.
+    `PluginStateManager`: `is_loaded`, `is_running`, `is_error`,
+    `get_last_update`, `get_error_info`, `get_state_info`.
+  - `CacheManager.load_cache`, `CacheManager.generate_sport_cache_key`,
+    `FontManager.measure_text`, `FontManager.get_native_bdf_size`,
+    `BaseOddsManager.get_odds_for_games`, `BaseOddsManager.format_odds_summary`,
+    `DynamicTeamResolver.get_available_dynamic_teams`,
+    `DynamicTeamResolver.is_dynamic_team`, `PluginTestCase`.
+- **Removed (core-internal, no caller):**
+  - `src/cache/cache_metrics.py`
+  - Vegas status/stats plumbing that nothing read (`get_status`,
+    `get_current_scroll_info`, `get_buffer_status`, `VegasModeConfig.to_dict`)
+  - the sync "new cycle" message, which no follower ever handled (followers
+    now ignore any message type they don't know)
+  - unused `OperationType` members, `PluginOperation.from_dict`,
+    `cancel_operation`
+  - the test-only `PluginCatalog` readers
+  - `IPC *Args.to_dict` and `client.ping()`
+  - `_parse_form_value`
+  - `CacheStrategyProtocol`
+  - `ErrorAggregator.on_pattern_detected` and `clear_old_records`
+  - the duplicate `create_error_response`/`create_success_response`
+- **Web UI:**
+  - `json-file-manager.js` was never mounted: the schema widget renders the
+    plugin's own file manager in an iframe.
+  - `example-color-picker.js` was a docs example; `utils/error_handler.js` had
+    one fallback caller.
+  - The 29 one-line `escapeHtml` shims now call `window.LEDEscape` directly.
+  - Four uncalled `PluginAPI` methods are gone.
+  - `window.escapeHtml`, `BaseWidget` and every widget name are unchanged.
+- **Scripts and dependencies:**
+  - One-off scripts removed: `add_defaults_to_schemas.py`,
+    `analyze_plugin_schemas.py`, `test_captive_portal.sh`,
+    `verify_wifi_before_testing.sh`, `dev/run_emulator.sh` (use
+    `python3 run.py -e`), `update_plugin_repos.py` (use
+    `git -C ../ledmatrix-plugins pull`).
+  - Unused pins dropped: `markupsafe` (Flask still installs it) and
+    `pytest-mock`.
+

+longer than a client waits (the MQTT bridge gives up after 15 s). So the
+start route never waits: it answers `202` with `status: "starting"`, and
+hands the request to the web process's one dispatcher
+([`web_interface/on_demand_dispatch.py`](../web_interface/on_demand_dispatch.py)).
+Its worker thread sends the request every 0.5 s while nothing is listening,
+until the display acknowledges it or the wait runs out (45 s after a cold
+start, `START_WAIT_SECONDS`; 10 s for a service that was already running,
+`ON_DEMAND_SOCKET_WAIT_RUNNING_SECONDS`). Any other failure ends it at once.
+One start is pending at a time: a newer start replaces it, and a stop
+cancels it (the stop then succeeds even with no display listening, and
+reports `cancelled_request_id`).
+
+The outcome is reported where clients already look:
+`GET /display/on-demand/status` answers the pending start's state
+(`source: "web"`, `status: "starting"`, or `status: "error"` with `error:
+"start-timeout"` or the socket's reason) until the display publishes
+something newer, and `GET /display/current-status` adds it as
+`on_demand_pending`.
+
+A delivered start keeps reading as `status: "starting"`, now with
+`delivered: true`, until the display publishes the state that answers it.
+The display acknowledges a start as soon as its socket opens, but its run
+loop acts on it only after the first screen is built (about 5 s on ledpi,
+while Vegas renders its first strip), and meanwhile it publishes its own
+idle state. The display's on-demand state names the request it answers
+(`request_id`), so "answers it" means the id matches. A display older than
+that field answers with any state published after the delivery. Either
+way the delivered start is reported for at most 30 s
+(`DELIVERED_SHOWN_SECONDS`).
 
 Brightness and plugin reload never had a mailbox: without the socket, the
 config watcher applies the saved brightness and a reload becomes the
 restart banner, as before.

 ### Plugins in the display process
 
 A plugin asks for the screen with `BasePlugin.request_on_demand()` and gives
 it back with `end_on_demand()` (see "On-demand display" in
 [PLUGIN_API_REFERENCE.md](PLUGIN_API_REFERENCE.md)). Neither goes through

 marked `source: 'plugin'`, to `DisplayController.submit_plugin_on_demand`,
 which queues it in memory (at most `PLUGIN_ON_DEMAND_QUEUE_SIZE`, 32) from
 whatever thread the plugin called on, and wakes the render thread through
 the socket's queue flag (`ControlServer.wake()`). The render thread applies
 it in `_drain_control_commands`, after the socket's commands, through the
 same `_handle_on_demand_request`, so it lands within a frame like a socket

+Speeds are solved against `limit_refresh_rate_hz`, the configured cap, but a
+cap is only a ceiling: a long chain, a high `pwm_bits` or a big
+`gpio_slowdown` can leave the panel below it. One Pi 4 driving 2×128×64 on

+every scroll runs that much slower than configured (60 px/s ran at 55 px/s),
+and the smooth speeds are the cap's rather than the panel's.
+
+The display measures the real rate from its own frames. About a minute
+into scrolling, a panel more than 3% short of its cap is logged once:
+
+```
+WARNING - src.common.frame_timing - The panel refreshes at about 113 Hz, below

+that fills in the suggested cap (`GET /api/v3/config/refresh-rate`). The

+`_logo_filename` seam beside it; basketball's tournament keys moved to its own
+`_extract_game_details` (its dict keeps them), football's missing-badge
+request to its own, and ufc's MMA extractor, which builds its own dict, uses the
+shared helpers. Every changed cell is one of the decisions below or a fix.
+All 208 harness renders of the nine are pixel-identical on core main.
+`src/common/sports_view_model.py` holds the bodies in one mixin,
+`SportsViewModelMixin`, whose docstring lists every key, its type and default;
+`test/test_sports_view_model_parity.py` compares them with the plugin copies.
+
+`period_text` is deliberately not given a default: the renderers read its
+absence (baseball's) as "draw ESPN's status text", which is how an
+extra-inning final reads "Final/10"; an empty default blanked baseball's
+Recent "Final". `period` (0) and `clock` ("") are, and baseball now carries
+them. `is_within_window` and `broadcast` are never read but are kept: keys are
+additive only.
+
+Left for later: the period labels stay in each sport's
+`_extract_game_details` (quarters, periods, halves, extra time, rounds), and
+soccer still names extra time's half-time "ETH"; ufc's MMA dict keeps its own
+keys and its ordinal date (`display_manager.format_date_with_ordinal`).

   nine. ufc stays on the shared body, dormant: its favourites are fighters,
   which its MMA managers match themselves (a follow-up). Fix ported: only a
   game with an id can be a duplicate in the selection methods.
-- **7, other-games rotation.** football advances the rotation window under
-  `_games_lock` (update() and display() both advance it; interleaved, a
-  window of games is skipped) and fixes a favourites-only pool that recomposed
-  the list on every frame. Port both. ufc does not attach odds to fights
-  rotated in: decide whether rotated fights show odds.
-- **8, rankings.** (a) afl, basketball, nrl and soccer turn a *standings*
-  payload into ranks (a pro league's standings position becomes the rank
-  badge); baseball, hockey, lacrosse, ufc and football do not. Which is
-  right is visible on every pro-league card with "show ranking" on.
-  (b) football also keys ranks by team id, so two schools sharing an
-  abbreviation across divisions cannot be confused: adopt for all.
-  (c) football asks for the division roster of the *season* year (July
-  onward is this year's season), which is right for football and wrong for
-  college basketball, hockey and lacrosse, whose ESPN season is the year it
-  ends: a per-sport seam, not football's constant. (d) baseball's
-  `_choose_poll` calls `dynamic_team_resolver.choose_top_division_poll`, the
-  others inline it: one home, in core.
-- **9, live fetch and odds.** (a) afl, basketball, nrl and soccer cache the
-  live scoreboard for 30 s under `<sport_key>_scoreboard_current`; the others
-  do not (the harness fixtures seed that key, so the change shows up there).
-  (b) basketball fetches college games with no `dates` parameter, citing a
-  404 (*verify* now that `espn_dates` handles ranges). (c) odds are fetched
-  three ways: blocking (hockey, lacrosse), a thread waited on for 1.5–2 s
-  (six plugins), or fire-and-forget for upcoming games (basketball). This
-  sets how long `update()` takes and when an odds line appears. (d) nrl
-  guards on a missing odds manager; port it.

+- **7, other-games rotation. Decided 2026-10-09, done:** two fixes ported
+  from football. The window advances under `_games_lock`: `update()` and
+  `display()` both advance it, and interleaved, each added a width and a
+  window of games was never shown. The display path's due-check looks at the
+  pool `_compose_selection` actually cuts from, including the unfiltered
+  fallback when nothing else survived. The other eight never rotated that
+  fallback between fetches (it moved only when `update()` ran, then several
+  windows at once); guessing it whenever the filtered pool was empty would
+  recompose an identical list on every frame while a favourite played.
+  Rotated-in fights in ufc follow its `show_odds` like every other fight (no
+  separate toggle; the rotation is dormant in ufc today, so no board
+  changes). `_rankings_loaded` is a seam (default: the abbreviation table is
+  non-empty; football counts its by-id table too). Kept for family 13: the
+  no-favourites branch of `update()` keeps its fixed "next N" in the eight
+  plugins that have it, rather than football's rotating pools.
+- **8, rankings. Decided 2026-10-12, reconciled.** Measured first, two of
+  the questions as first written did not hold. (a) afl, basketball, nrl and
+  soccer could turn a *standings* payload into ranks, but the branch never
+  ran: rankings are fetched only where `_league_has_rankings()` (a college or
+  NCAA league), and ESPN's site-API /standings answers `{}` or a link stub,
+  never a table. Deleted. The same four data sources asked /standings first
+  for any college league outside a fixed list, so a custom NCAA soccer
+  league (`usa.ncaa.m.1`) never showed its coaches poll; every college or
+  NCAA league now asks /rankings first, as in the other five (fix, visible
+  only there). (b) Ranks are kept by ESPN team id too, in all nine, and a
+  game with ids is ranked by id: ESPN lists Ohio State and Ohio State Newark
+  both as OSU. Changes the "ranked" filter and the other-games order only
+  where abbreviations collide; the badge still reads the abbreviation table.
+  (c) Only college football has division rosters (all nine carry the same
+  one-league table; college basketball, hockey and lacrosse publish none), so
+  football's July rule is promoted as is and there is no seam. In the other
+  eight the calendar year was unreachable. (d) One poll rule, in core:
+  `_choose_poll`, with `choose_top_division_poll()` for the resolvers that
+  expand `AP_TOP_n` (baseball's helper and the others' inline copies call it
+  once they adopt). (e) A poll from a season that has ended loads nothing:
+  ESPN keeps serving the last poll between seasons (on 2026-10-12, college
+  basketball's April final and college lacrosse's May poll), and each block
+  carries its season's `endDate`, so no calendar and no per-sport seam. No
+  badge shows and the "ranked" filter fails open until the new season's
+  first poll; visible on college basketball and lacrosse boards between
+  seasons. A block without a readable `endDate` counts as current. (f)
+  baseball's MLB, MiLB and NCAA Baseball managers drop their class-level
+  shared copy of the table (none of those leagues publishes a poll).
+- **9, live fetch and odds. Decided 2026-10-12, reconciled.** (a) Live
+  scores are always fresh: every poll asks ESPN and leaves the answer under
+  the shared `espn_scoreboard_cache_key` for its dates (`max_age=1`: only a
+  copy another reader fetched within the last second, the managers of one
+  display tick, is reused). afl, basketball, nrl and soccer had held it 30 s
+  under `<sport_key>_scoreboard_current`, so with the 15 s default poll every
+  other poll repeated the last one; lacrosse and ufc now share their copy.
+  (b) College basketball is asked by date like every other league: ESPN
+  answered single dates for both college leagues on 2026-10-12 (the 404 no
+  longer happens), so the lookback now reaches last night's late games there
+  too. `groups=50` is a separate question (left above). (c) Odds never block
+  `update()`: one daemon worker per manager answers a queue and attaches each
+  line in place under `_games_lock`; one batch in flight per manager, games
+  queued meanwhile join it. A card can draw once without odds and gain them;
+  a pre-rendered scroll strip gains them when it is next rebuilt. (d) The
+  missing-odds-manager guard (nrl's, already in `_attach_odds_to_rotated_games`
+  since family 7) is in `_fetch_odds` too, logged at debug, not ERROR. Fix
+  ported: an answer with `"events": null` is no games instead of a
+  `TypeError` out of the fetch (all nine), and `get_espn_scoreboard` no longer
+  caches it under the shared key.
+- **10, view model. Decided 2026-10-13, reconciled.** Additive only: no key
+  is renamed or removed. (a) One rule for a final, in all nine: state "post",
+  not `completed: false` (a payload without the flag is judged on state and
+  name), and not a not-played status, the union of the nine lists (postponed,
+  canceled, suspended, abandoned, delayed, a pending forfeit or no-contest).
+  A forfeit is a result (basketball and soccer had it as not played). (b)
+  Scores are integer text everywhere ("21" for 21, "21.0" or {"value": 21};
+  "0" for a missing or empty one, never "None"). (c) Halftime reads "HALF",
+  with no period or clock, in every sport's `period_text` (basketball,
+  football, hockey and lacrosse showed the period while ESPN said "in"; nrl
+  and soccer appended "0:00"). (d) A time without an offset is UTC (hockey and
+  lacrosse read US Eastern, ufc the host's zone). Fixes ported: football's
+  postponed or canceled game says so, not "Final"; the team-schedule record
+  shape is read in all nine; a logo URL is `team.logo`, else `logos[0].href`;
+  a team id is the competitor's, else its team's (eight dropped the game);
+  ufc never shows a score of "None"; a called-off game ESPN still reports as
+  "in" is not live (baseball's guard). Superset: ufc's fights carry
+  `favorite_teams` ([]), baseball's games `period` and `clock`. Per-sport:
+  ufc's own dict and ordinal date, nrl's id-based logo file and favourites,
+  the period labels.

+"""The live poll's scoreboard request and the odds requests (sports family 9).
+
+The scoreboards' live fetch and odds code, reconciled in ledmatrix-plugins
+(family 9) from seven and three bodies into one each, and copied here under
+the existing names. All of it lives on the plugins' ``SportsCore``, so there
+is one mixin, ``SportsLiveFetchMixin``:
+
+- ``_fetch_todays_games()``: today's scoreboard for the live poll, with
+  yesterday's while it can still hold a live game (``_needs_previous_day``),
+  as ``{"events": [...]}``; None when ESPN cannot be reached.
+- ``_fetch_odds(game)``: queue one game for an odds request; returns at once.
+- ``_drain_odds_queue()``: the odds worker that answers the queue.
+
+THE RULES (decided 2026-10-12)
+------------------------------
+Live scores are always fresh. Every poll asks ESPN (``get_espn_scoreboard``
+with ``max_age=1``: only a copy another reader fetched within the last second,
+the managers of one display tick, is reused) and leaves the answer under the
+shared ``espn_scoreboard_cache_key`` for its dates, so odds-ticker and every
+other reader of the same day share it. The plugins' old 30 s cache under
+``<sport_key>_scoreboard_current`` is gone. College basketball is asked by
+date like every other league; ESPN answered single dates for it on 2026-10-12
+(the old no-dates request cited a 404 that no longer happens). An answer whose
+``events`` is not a list counts as no games.
+
+Odds never block ``update()``. ``_fetch_odds`` puts the game on the manager's
+queue and starts one daemon worker if none is running; the worker asks the
+odds manager for each queued game in turn and attaches the line to every
+dict queued for that id, in place, under ``_games_lock`` (display() reads the
+games under it), so a card can draw once without odds and gain them when
+ESPN answers. One batch in flight per manager: a game queued while the worker
+is busy joins its batch, so a slow endpoint never stacks threads or requests.
+The odds manager bounds each request (core's ``BaseOddsManager``: 5 s, then a
+60 s hold-off). A live game's line is cached ``live_odds_update_interval``
+(60 s), any other ``odds_update_interval`` (3600 s). Without ``show_odds``, a
+game id or an odds manager nothing is asked (the last logged at debug).
+
+Before the reconcile, six plugins waited on a worker for 1.5 s (2 s for a
+live game) per game and hockey and lacrosse asked on the calling thread: with
+a 3 s endpoint, ``update()`` of four upcoming games took 6 s and 12 s, and in
+the six the line appeared only at the next ``update()`` (an hour later for an
+upcoming game).
+
+A new module rather than more methods on ``sports_fetch``, for the reason
+``sports_helpers`` gives: a missing module fails at load, where the version
+checks see it; a missing method fails mid-update.
+
+WHAT A HOST MUST PROVIDE
+------------------------
+Derived by walking every ``self.<attr>`` the mixin reads; the host-contract
+test in ``test/test_sports_live_fetch.py`` fails if a read is added without
+being listed here. Every scoreboard ``SportsCore`` supplies all of them.
+
+- ``session``, ``headers``, ``cache_manager``, ``logger``, ``sport``,
+  ``league`` -- the scoreboard request.
+- ``_needs_previous_day`` -- from ``SportsFetchMixin``.
+- ``show_odds``, ``mode_config`` (the two odds intervals), ``sport_key`` (the
+  worker's thread name), ``_games_lock`` (a lock display() also holds).
+- ``odds_manager``, read with ``getattr`` -- ``get_odds(sport=, league=,
+  event_id=, update_interval_seconds=)``.
+- ``_odds_pending`` and ``_odds_worker_busy`` -- the queue and whether a
+  worker is running; created here on first use, under ``_games_lock``.
+
+The game dict's ``id`` and ``is_live`` are read; ``odds`` is written.
+
+BASE ORDER
+----------
+No other mixin defines these names, so the position in the bases does not
+change which body runs; a method on the plugin's own class still wins. The
+mixin has no ``__init__``.

+"""Which teams are ranked, and in which poll (sports family 8).
+
+The scoreboards' rankings code, reconciled in ledmatrix-plugins (family 8)
+from three, three and two bodies into one each, and copied here under the
+existing names. All of it lives on the plugins' ``SportsCore``, so there is
+one mixin, ``SportsRankingsMixin``:
+
+- ``_fetch_team_rankings()``: the top-division poll from the data source,
+  hourly, as ``_team_rankings_cache`` ({abbreviation: rank}, what the rank
+  badge draws) and ``_ranked_team_ids`` ({ESPN team id: rank}). Only for a
+  league ``_league_has_rankings()`` says publishes a poll.
+- ``_choose_poll(rankings_data)``: the first block ESPN lists that is a
+  top-division poll; seedings and the polls of lower divisions are stepped
+  over, ESPN's order is otherwise kept (so the CFP rankings take over from AP
+  when ESPN fronts them). ``choose_top_division_poll`` below is the same rule
+  for code with no scoreboard to hand (the dynamic team resolvers).
+- ``_poll_season_ended(poll, now)``: whether the poll's season is over.
+- ``_load_division_team_ids()``: team ids per college football division
+  (FBS, FCS) from ESPN's group rosters, for the season year.
+- ``_ranked_positions(game)``, ``_is_ranked_game(game)``, ``_best_rank(game)``:
+  the poll positions either side holds, by team id first, abbreviation second.
+- ``_passes_other_filters(game)``: whether a non-favourite game is worth a
+  slot under ``other_games_min_quality`` and ``other_games_divisions``.
+
+THE RULES (decided 2026-10-12)
+------------------------------
+Ranks are kept by ESPN team id as well as by abbreviation, and a game with ids
+is ranked by id: abbreviations are not unique (ESPN lists Ohio State and Ohio
+State Newark both as OSU) and an id cannot rank the wrong school. The badge
+still draws from the abbreviation table.
+
+A poll whose season has ended loads nothing. ESPN keeps serving the last poll
+it published until the next one (on 2026-10-12 college basketball's /rankings
+was still April's final poll, college lacrosse's May's), and every block names
+its season with an ``endDate``. Past it the table stays empty, so no badge
+shows and the "ranked" filter fails open, until the new season's first poll
+arrives. Read from the payload, not a calendar, so no league needs its own
+season dates; a block without a readable ``endDate`` counts as current.
+
+The division rosters are asked for the season year (July onward is this
+year's season): college football's season runs into January, and the next
+season's groups do not exist then. Only college football has division
+rosters (``_DIVISION_GROUPS_BY_LEAGUE``), so this is football's rule as is,
+not an override point.
+
+Everything fails open: no poll, an empty roster or a failed request allows
+every game rather than blanking the board.
+
+The data source decides the endpoint (``data_source.fetch_standings``, still
+per plugin); every scoreboard asks /rankings first for a college or NCAA
+league. A standings table is never turned into ranks.
+
+A new module rather than more methods on ``sports_shared``, for the reason
+``sports_helpers`` gives: a missing module fails at load, where the version
+checks see it; a missing method fails mid-update.
+
+WHAT A HOST MUST PROVIDE
+------------------------
+Derived by walking every ``self.<attr>`` the mixin reads; the host-contract
+test in ``test/test_sports_rankings.py`` fails if a read is added without being
+listed here. Every scoreboard ``SportsCore`` supplies all of them.
+
+- ``logger``, ``sport``, ``league``.
+- ``data_source`` -- ``fetch_standings(sport, league)`` returns the payload
+  (``{}`` on failure).
+- ``session`` -- ``get(url, params=..., timeout=...)`` for the division
+  rosters; ``cache_manager`` (may be ``None``) -- ``get(key)`` and
+  ``set(key, value, ttl=...)`` keep them a day.
+- ``_team_rankings_cache``, ``_ranked_team_ids`` and
+  ``_rankings_cache_timestamp`` -- the tables and when they were fetched
+  (0: never). Written here. ``_rankings_cache_duration`` -- seconds between
+  fetches.
+- ``_division_team_ids`` (``None``: never loaded) and ``_division_loaded_at``
+  -- the rosters and the monotonic time they were loaded. Written here.
+- ``other_games_min_quality`` and ``other_games_divisions`` -- the filters.
+- ``_league_has_rankings`` and ``_game_divisions`` -- from
+  ``SportsCoreSharedMixin``.
+- ``_rankings_loaded`` -- from ``SportsRotationMixin`` (football-scoreboard
+  overrides it to count the id table too).
+
+The methods read the game dict's ``home_id``, ``away_id``, ``home_abbr`` and
+``away_abbr``; any may be missing.
+
+BASE ORDER
+----------
+No other mixin defines these names, so the position in the bases does not
+change which body runs; a method on the plugin's own class still wins. The
+mixin has no ``__init__``; the state it writes is the host's.

+"""Which non-favourite games a scoreboard shows, and when the slice moves (sports family 7).
+
+The scoreboards' other-games rotation, reconciled in ledmatrix-plugins
+(family 7) from two bodies each into one, and copied here under the existing
+names. All of it lives on the plugins' ``SportsCore``, so there is one mixin,
+``SportsRotationMixin``:
+
+- ``_by_importance(games, newest_first)``: the non-favourite pool, best
+  matchup first and one game per team, when a poll has loaded; kickoff order
+  otherwise. ``SportsCoreSharedMixin._favorites_first`` asks it for both the
+  filtered and the unfiltered pool.
+- ``_other_games_window(others, limit)``: the slice of a pool on screen now.
+  It advances by its own width every ``other_rotation_interval_seconds``
+  (catching up on intervals that passed unseen) and wraps.
+  ``SportsCoreSharedMixin._compose_selection`` cuts with it.
+- ``_advance_other_games_if_due`` and ``_rotate_other_games_on_display``:
+  the display path's re-cut between fetches. The plugins' ``display()`` calls
+  ``_rotate_other_games_on_display`` before its dwell check; the card on
+  screen keeps its place if it survived the cut.
+- ``_attach_odds_to_rotated_games``: odds for the games a rotation
+  brought in, on a daemon thread, when ``show_odds`` is on and there is an
+  odds manager.
+- ``_rankings_loaded()``: the override point (below).
+
+THE RULES
+---------
+``update()`` (through ``_favorites_first``) and ``display()`` (through
+``_rotate_other_games_on_display``) both advance the window, so the advance
+holds ``_games_lock`` (the plugins' RLock): interleaved without it, both saw
+the interval elapse and each added a width, skipping a window nobody saw.
+
+The display path's due-check looks at the pool ``_compose_selection`` will
+actually cut from: the filtered others, or, when nothing survived at all (no
+favourite to show either), the unfiltered fallback. Guessing the unfiltered
+pool whenever the others were empty recomposed an identical list on every
+frame while a favourite was playing; never looking at it left the fallback
+moving only when ``update()`` ran.
+
+Rotated-in games get odds by the same rule as the games ``update()`` picks:
+``show_odds`` on (decided 2026-10-09, which brought ufc-scoreboard in line).
+
+OVERRIDE POINT
+--------------
+``_rankings_loaded()`` -- did a poll load? ``_by_importance`` keeps kickoff
+order when not. The default is ``_team_rankings_cache`` being non-empty.
+football-scoreboard overrides it to count its rankings keyed by ESPN team id
+(``_ranked_team_ids``) as well, the table its ``_best_rank`` reads first.
+
+A new module rather than more methods on ``sports_shared``, for the reason
+``sports_helpers`` gives: a missing module fails at load, where the version
+checks see it; a missing method fails mid-update.
+
+WHAT A HOST MUST PROVIDE
+------------------------
+Derived by walking every ``self.<attr>`` the mixin reads; the host-contract
+test in ``test/test_sports_rotation.py`` fails if a read is added without being
+listed here. Every scoreboard ``SportsCore`` supplies all of them.
+
+- ``other_rotation_interval_seconds`` -- seconds per window; 0 pins it.
+- ``_other_window_start`` and ``_other_window_rotated_at`` -- the window's
+  position and the monotonic time it last moved (0: never cut). Written here.
+- ``_games_lock`` -- the re-entrant lock around ``games_list``.
+- ``_selection_pools`` -- what ``_favorites_first`` settled (``favorites``,
+  ``others``, ``unfiltered``, ``favorite_limit``, ``other_limit``); read with
+  getattr, so a manager that never built it does not rotate.
+- ``_compose_selection`` -- from ``SportsCoreSharedMixin``.
+- ``_best_rank`` -- a game's better poll position, 99 if neither side ranks
+  (family 8: ``src.common.sports_rankings``).
+- ``_team_rankings_cache`` -- read with getattr by the default
+  ``_rankings_loaded``.
+- ``games_list``, ``current_game``, ``current_game_index``,
+  ``last_game_switch`` -- the switch-mode state a rotation swaps.
+- ``logger`` -- one INFO line per rotation.
+- ``show_odds`` and ``odds_manager`` (read with getattr), ``mode_config``
+  (``odds_update_interval``), ``sport``, ``league`` and ``sport_key`` -- the
+  rotated-in odds fetch.
+
+The methods read the game dict's ``id``, ``start_time_utc``, ``home_abbr``,
+``away_abbr`` and ``odds``; any may be missing.
+
+BASE ORDER
+----------
+No other mixin defines these methods, so the position in the bases does not
+change which body runs; a method on the plugin's own class (football's
+``_rankings_loaded``) still wins. The mixin has no ``__init__``; the state it
+writes is the host's.

+The scoreboards' ``_extract_game_details_common``, reconciled in
+ledmatrix-plugins (family 10) from nine bodies into one, and copied here
+under the existing names with the helpers it calls. It lives on the plugins'
+``SportsCore``, so there is one mixin, ``SportsViewModelMixin``:
+
+- ``_extract_game_details_common(game_event)``: one ESPN scoreboard event to
+  ``(details, home competitor, away competitor, status, situation)``, or five
+  Nones when the event has no competition, status, date or home/away pair.
+  Each sport's ``_extract_game_details`` adds its extras to ``details``.
+- ``_status_is_final(status_type)``: whether ``status.type`` is a result.
+- ``_score_text(score)``: a competitor's score as integer text.
+- ``_team_logo_url(competitor)``, ``_extract_team_record(competitor)``.
+- ``_logo_filename(abbr, team_id)``: the seam below.

+THE KEYS
+--------
+Additive only: a key is never renamed or dropped, because every renderer
+(``sports.py``'s scorebug, ``game_renderer.py``'s card, ``sports_card``,
+``sports_game_renderer``, ``sports_shared``, ``sports_game_over``,
+``sports_vegas``...) reads them. A sport's extras (down and distance, innings,
+shots, tournament seeds...) belong in its own ``_extract_game_details``.

+``period_text`` is not set here: each sport's extractor sets it, and the
+renderers read its absence (baseball's) as "draw ESPN's status text", which
+is how an extra-inning final reads "Final/10".
+
+THE RULES (decided 2026-10-13)
+------------------------------
+A game is final when its state is "post", ESPN has not marked it
+``completed: false`` (a payload without the flag is judged on state and name
+alone), and its status is not one of ``_NOT_PLAYED_STATUS_NAMES``: postponed,
+canceled, suspended, abandoned (``_CALLED_OFF_STATUS_NAMES``), delayed, or a
+pending forfeit or no-contest. A forfeit is a result. A called-off game is
+never live, even while ESPN still reports it "in". Scores are integer text in
+every sport: 21, "21.0" and {"value": 21} are "21"; a missing, empty or
+non-numeric score is "0". Halftime reads "HALF" with no clock in every
+sport's ``period_text`` (each sport's own extractor, not this module).
+
+THE SEAM
+--------
+``_logo_filename(abbr, team_id)``: the file under ``logo_dir`` a team's logo
+is kept in. Default ``<ABBR>.png`` (``LogoDownloader.normalize_abbreviation``);
+NRL overrides it with ``<ABBR>_<id>.png`` because its abbreviations are not
+unique ("NEW" is two clubs).
+
+A new module rather than more methods on ``sports_fetch``, for the reason
+``sports_helpers`` gives: a missing module fails at load, where the version
+checks see it; a missing method fails mid-update.
+
+WHAT A HOST MUST PROVIDE
+------------------------
+Derived by walking every ``self.<attr>`` the mixin reads; the host-contract
+test in ``test/test_sports_view_model.py`` fails if a read is added without
+being listed here. Every scoreboard ``SportsCore`` supplies all of them.
+
+- ``logger``, ``config`` (``display.use_short_date_format``), ``logo_dir``
+  (a ``Path``), ``favorite_teams`` (a list or None), ``_get_timezone``
+  (a callable returning the zone game times are shown in).
+
+BASE ORDER
+----------
+No other mixin defines these names, so the position in the bases does not
+change which body runs; a method on the plugin's own class still wins. The
+mixin has no ``__init__``.
