4grayandClaude Opus 5.5 4e512c1fd9 perf(dashboard): stop idle dashboard ticks that have nothing to update
Three timers kept an idle dashboard busy (plan D3 audit):

- The portal live-EPG presenter ran a 30 s interval even with no portal
  card wanted, so every dashboard paid a full change-detection pass per
  tick. A component-provided DashboardLiveEpgClock now drives both live-EPG
  presenters and every progress bar. It runs only while one of them has a
  live card and only while the document is visible, and reads the clock at
  once when it starts again.
- The XMLTV presenter re-asked every scope and emitted a new Map on each
  tick. It now re-asks only after a programme on air has ended or while a
  key has no programme, and drops unchanged answers. Progress still moves
  on each tick because details read the clock signal.
- The source-expiry badges polled the clock every minute and rebuilt the
  sources rail. createSourceExpiryClock arms one timer for the next day
  boundary (nextSourceExpiryChangeMs), capped at an hour, and none when no
  badge can change.

The rail rebuilt its scroll position and IntersectionObserver targets on
every new items array; it now does so only when card ids or order change,
which also stops a user-scrolled rail from snapping back each tick.

Workspace Dashboard Feature

This library owns the workspace dashboard rails UI. The dashboard is a read-only surface over existing playlist, recent, favorites, EPG, and Xtream catalog data; it should not introduce Electron IPC, SQLite schema, or route contracts on its own.

Dashboard Surfaces

The dashboard renders a surface only when the matching setting is enabled. Data rails also require the underlying data slice to have at least one item.

  • hero shows the full-width cinematic banner that rotates between the newest unfinished title, a favourite (or recent) channel with a programme on air, and favourite / recently added titles. Contract: docs/architecture/workspace-dashboard.md#cinematic-hero.
  • continueWatching shows recent movies and series from DashboardDataService.globalRecentVodItems() using cover cards with playback progress when a saved resume position is available.
  • liveFavorites shows favorited live TV channels from DashboardDataService.globalFavoriteLiveItems() using the channel layout with EPG title, time range, and progress when XMLTV data is available.
  • recentlyWatchedLive shows recently watched live TV channels from DashboardDataService.globalRecentLiveItems() using the same channel layout.
  • favoriteMoviesAndSeries shows favorited movies and series from DashboardDataService.globalFavoriteItems(), excluding live favorites, using cover cards.
  • recentSources shows recently used playlist/source entries.
  • xtreamRecentlyAdded shows recently added Xtream catalog items.
  • tmdbRecommendations shows "Because you watched X" — TMDB recommendations seeded from recently watched movies/series, kept to titles that exist in an imported Xtream library. Needs the TMDB opt-in and the Electron DB worker (hidden in the PWA), and hides itself below five matched cards. Data: DashboardRecommendationsService in workspace/dashboard/data-access.
  • tmdbTrending shows TMDB's weekly trending titles, matched against the imported Xtream libraries. Same TMDB/Electron gating; unmatched cards open the global search prefilled. Data: DashboardTrendingService.

Settings

Per-surface visibility lives on Settings.dashboardRails as a DashboardRailsSettings object. Every surface defaults to enabled. Stored settings are deep-merged with DEFAULT_DASHBOARD_RAILS_SETTINGS by SettingsStore, so existing users and older partial settings keep newly added surfaces visible unless they explicitly turn them off.

The global showDashboard flag remains a top-level Settings property because workspace startup and route guards already depend on that contract. The Settings UI groups showDashboard and the per-surface checkboxes in the Dashboard section. When showDashboard is off, the per-surface checkboxes are disabled because the dashboard route itself is hidden.

Navigation

Rail cards use the navigation state provided by DashboardDataService for the underlying item. Rail "See all" links may also pass router state:

  • live rails open the relevant collection on Live TV.
  • cover rails for movies/series open Global Recent or Global Favorites on Movies when movie items are present, otherwise on Series.

This keeps the global collection pages from defaulting to Live TV when a dashboard rail is clearly about movies or series.
