- pruneEphemeralMaps now uses getCached() so TTL-expired entries also
drop their XMLTV preview / channel-id mapping, instead of clinging
to them until the next explicit cache read.
- portal-channels-list attaches a .catch() to the now-async enqueue so
any future internal rejection surfaces in the console rather than
bubbling silently as an unhandled promise rejection.
- XtreamXmltvFallbackService binds the bridge receiver when calling
the extracted function reference, in case a preload wrapper relies
on `this`.
Adds a regression test for the TTL-aware prune.
Live TV channels in Xtream playlists go blank whenever the provider's
get_short_epg returns nothing, even when the user has working XMLTV
URLs in Settings. The XMLTV pipeline already populates epg_programs
but only the M3U module was reading it.
Wire those uploads up as a fallback for Xtream too: when the provider
returns nothing for a channel with an epg_channel_id, look it up in
the local table. A settings toggle flips the priority for users whose
curated XMLTV is better than the provider's auto guide.
EpgQueueService.enqueue() became async to batch the XMLTV lookup once
per viewport change. To keep the queue consistent under fast scroll,
all shared-state mutations now happen behind a generation counter so
only the latest call commits. Per-method bridge gating in the new
XtreamXmltvFallbackService keeps each path working when the preload
exposes only one of the two endpoints.
Audit followup to the support-loop and volume-restart fixes. Two more
effects pulled in transitive signal deps that would have caused the same
class of regression the next time the surrounding helpers grew.
1. Component session-fan-out effect: the body called
scheduleControlsHide(), which reads isPlaying/menus.anyOpen/statusLabel/
controlsVisible. Those became tracked deps of the effect, so opening a
popover, pausing, or hovering re-ran the whole body — re-emitting
timeUpdate. If a parent ever wires timeUpdate back into
playback.startTime as a "resume where I left off" feature, this would
have been the next stream-restart bug. Wrap the side-effect block in
untracked() so the effect only listens to session changes.
2. Controller stalled-tracker effect: tracked the full session signal
even though only status was needed. The session payload updates ~2 Hz
during playback (positionSeconds advances), making the effect re-run
constantly to call a no-op. Add a sessionStatus computed and track
that instead — fires only on real status transitions.
No behavior change for current users; both fixes are preventative.

Same root cause as the loading-loop fix: the session-creation effect
read this.volume() while building startSession's initialVolume argument,
which made volume a tracked dependency of the effect. Each volume tick
re-ran the effect, the cleanup disposed the active session, and a fresh
one was created — which for VOD/series meant restarting playback from
the beginning.
Read volume via untracked() inside the effect. The value is only needed
once at session creation; subsequent volume changes flow through
controller.applyVolume() and never go near the effect.

Regression introduced in the bundle 3 refactor. After calling
prepareEmbeddedMpv, the controller wrote the response back into
this.support — but the component's session-creation effect tracks
this.support(), so updating it cleaned up the just-created session and
ran startSession again, which prepared again, set support again, and so
on. Net effect: endless "Loading stream…" spinner because every session
was disposed before MPV could finish loading the file.
The initial loadSupport() in the constructor already populates support
(including capabilities). Drop the redundant set in startSession; leave
a comment explaining why so it does not get re-added.

The timeline and volume sliders were rendering invisibly because:
- --embedded-mpv-accent resolved to var(--mat-sys-primary) with no
fallback. If the Material 3 theme tokens did not cascade into the
component scope, the variable was empty and both the thumb and the
Firefox progress fill rendered with no color.
- The track contrast was 22% of var(--mat-sys-on-surface) which has the
same scoping fragility on top of being subtle even when it does
resolve.
- The thumb had no border, so even when accent was present it could
blend into similarly-toned popover backgrounds.
- The played portion of the timeline had no fill in Chromium because
::-webkit-slider-runnable-track does not support a native progress
state.
Fixes:
- Add hard fallbacks on every theme-token reference (accent falls back to
#7dd3fc, surface to #0f1620, outline-variant to a translucent white).
- Add --embedded-mpv-track and --embedded-mpv-thumb-ring as theme-
independent CSS variables so the slider stays legible regardless of
the parent theme provider.
- Give the thumb a 2 px white ring border + a stronger drop shadow so it
reads on any background (panel glass, dark backdrop, accent-coloured
area).
- Implement played-progress fill via a linear-gradient on
::-webkit-slider-runnable-track keyed off a CSS variable
--slider-progress, set per-slider from the template based on the
current playback position / volume. Firefox uses native
::-moz-range-progress.
- Tidy disabled state styling so live-stream timelines (no duration)
are dim but still visible.

The renderer was reading session.id and forwarding it to the addon, but
during the loading window that id is the placeholder
"embedded-mpv-starting" set by createLoadingSession. If the user adjusted
volume, seeked, or toggled audio/subtitle/speed/aspect before the addon's
createSession returned the real id, that placeholder id reached the
addon — and the addon's getSessionOrThrow threw a raw std::runtime_error
which libc++abi terminated the process on.
Two fixes, defense in depth:
1. Renderer (session controller): use the canonical sessionId() signal,
which is null until the addon hands back a real id, as the gate for all
IPC calls. Wrap every IPC call in a guardIpc helper that swallows
addon-side throws so a torn-down session or race won't surface as an
uncaught promise rejection.
2. Native (embedded_mpv.mm): change getSessionOrThrow to take a
Napi::Env and throw Napi::Error::New(env, ...) instead of
std::runtime_error. node-addon-api converts Napi::Error to a JS
exception cleanly; the previous std::runtime_error escaped the C++
frame and aborted the process when the addon was built without
NAPI_CPP_EXCEPTIONS translation. Refactor splits findSession (returns
nullptr) from getSessionOrThrow (env-aware) so call paths that just
probe a session's existence don't pay the throw cost.
The native fix needs an addon rebuild to take effect; the renderer fix
prevents the crash trigger immediately.

Same root cause as the modal-dialog occlusion: control popovers (volume,
audio, subtitle, speed, aspect) extend upward from the controls strip into
the area covered by the MPV NSView. They render in DOM but the native view
paints over them.
Replace the simple boolean overlayActiveProvider with a richer
boundsProvider closure on the session controller. The component drives it
from both the modal overlay state and the popover menu state:
- Modal dialog open (command palette, MatDialog) -> HIDDEN_BOUNDS, MPV
fully off-screen so the dialog has the whole window.
- Popover menu open -> shrink MPV from the bottom by 300 px so the popover
region lives in DOM-receiving space; video keeps playing in the upper
region instead of disappearing entirely.
- Otherwise -> full host bounds.
Bounds-resync effect now tracks menus.anyOpen() in addition to
overlayActive() so opening or closing a popover triggers an immediate
re-sync.

The component had grown to ~1000 lines with session lifecycle, IPC plumbing,
keyboard shortcuts, popover state, formatters, and view orchestration all
living in one file. Per CLAUDE.md's 350–400 line hard cap, split into:
- embedded-mpv-format.utils.ts (~100): pure helpers (formatTime, track
labels, volume icon/label, persisted-volume access, measureBounds) and
preset constants (SPEED_PRESETS, ASPECT_PRESETS, HIDDEN_BOUNDS).
- embedded-mpv-shortcuts.ts (~90): EmbeddedMpvShortcuts class that owns the
document keydown listener and routes through a handler interface; the
component just provides callbacks.
- embedded-mpv-ui-state.ts (~110): EmbeddedMpvMenuState (single-open
popover state machine with toggle/open/close/closeAll + anyOpen signal)
and EmbeddedMpvFeedback (transient overlay with auto-clearing flash).
- embedded-mpv-session-controller.ts (~395): component-scoped Injectable
that owns support/session/sessionId/stalled/retryToken signals, the
session-update IPC subscription, bounds-sync (resize, scroll, overlay
state), the stalled timer, and all per-session IPC operations
(togglePaused, seekBy, seekTo, applyVolume, setAudioTrack,
setSubtitleTrack, setSpeed, setAspect, retry).
- embedded-mpv-player.component.ts (now ~540, was ~1000): view-only
orchestration — view children, derived computed signals, DOM event
listeners (pointerdown/pointermove/fullscreenchange/dblclick), and three
effects (session start/teardown, overlay-active bounds sync, session
payload → volume/timeUpdate fan-out).
No behavior changes. Build clean, electron-backend tests still pass.
Component is still over the 400-line cap but the bulk of its size is now
the necessarily-coupled-to-view computed signals and constructor effects;
the remaining over-cap delta is structural to a player root.

Native addon (apps/electron-backend/native/src/embedded_mpv.mm)
- Extend SessionSnapshot with subtitleTracks, selectedSubtitleTrackId,
playbackSpeed, aspectOverride.
- Refactor track parsing into a shared updateTracksFromNode helper that
filters by mpv "type" so audio and subtitle tracks share the code path.
- Observe sid, speed, video-aspect-override; clear sub state on
MPV_EVENT_START_FILE.
- Export setSubtitleTrack (handles trackId === -1 as "no" to disable),
setSpeed (clamped to 0.25–4.0), setAspect (passthrough string for
video-aspect-override).
- Snapshot output now includes the new fields.
Service (embedded-mpv-native.service.ts) + IPC + preload
- Mirror methods on EmbeddedMpvNativeService with capability detection: each
method throws a descriptive error if the loaded addon doesn't expose the
underlying native function (i.e. user is running an older build).
- New IPC channels EMBEDDED_MPV_SET_SUBTITLE_TRACK, _SET_SPEED, _SET_ASPECT
registered in events file and exposed via preload.
- Extend EmbeddedMpvSupport with a capabilities probe so the renderer can
hide controls for features the current addon build doesn't ship.
Renderer (embedded-mpv-player.component.{ts,html})
- Three new popovers anchored above their buttons (subtitle / speed /
aspect), gated by capabilities() and (for subtitles) by track count.
- Subtitle popover includes an Off entry; speed/aspect use fixed presets.
- Error state now surfaces the same overlay as the stalled state, with a
Retry button that bumps the existing retryNonce signal — covers #8 from
the audit.
- All session-payload defaults (loading stub, error stub, refresh fallback,
dispose payload, native createSession default) updated for the new
required fields.
NOTE: Existing addon binaries do not expose the new methods. Until the
addon is rebuilt (pnpm run serve:backend:embedded-mpv or the release
build script), capabilities will report subtitles/playbackSpeed/
aspectOverride as false and the new buttons will simply not appear.

- Volume button now toggles mute on click; the slider opens via hover/focus
in an absolute popover anchored above the button (with hover-bridge so the
cursor can reach it without crossing a dead zone). Wheel over the volume
area adjusts volume.
- Audio track menu likewise becomes a click-toggle popover anchored to its
button instead of a panel takeover; the back-arrow / mode-panel
scaffolding is gone.
- Slider gets explicit thumb/track styling for both WebKit and Firefox so
it reads as part of the design system instead of a raw native control;
aria-valuetext on the timeline announces formatted time.
- Stalled overlay: if status remains "loading" for 30 s, surface a centered
warning with a Retry button that disposes the session and recreates it
via a retryNonce signal the playback effect tracks.
- Keypress feedback overlay: ←/→ seek, ↑/↓ volume, M mute now flash a
centered pill with the icon + delta so the action is visible (especially
important in fullscreen where the controls are hidden).

Add the standard set of player shortcuts to match the audio/HTML video
players already in the app:
- Space, K — play/pause
- F — toggle fullscreen
- Left/Right — seek -5 s / +5 s
- Up/Down — volume +/- 5 %
- M — toggle mute (restores prior volume)
Shortcuts are ignored while focus is in an input/select/textarea or while
any MatDialog (e.g. command palette) is open, so the palette's filter and
dialog inputs keep their keys. Volume changes route through a shared
applyVolume helper so keyboard/wheel/slider all persist to localStorage
and the active session.
Also bind dblclick on the player root to toggle fullscreen, with a guard
so double-clicks on buttons/sliders don't trigger it. Note: the native
MPV NSView intercepts mouse events over the video itself, so dblclick
only fires on DOM-receiving regions (currently the controls strip).

The command palette is a MatDialog with a transparent backdrop, and the
prior MutationObserver-only detector did not reliably catch it across
overlay-container instantiation timing — the player kept rendering at full
bounds while the palette was open and continued occluding it. Subscribe
directly to MatDialog.afterOpened / afterAllClosed for the authoritative
"any modal dialog open" signal, and keep the OverlayContainer mutation
observer as a fallback for non-dialog CDK overlays. Either signal flips
overlayActive, hiding the embedded MPV view as before.

The native MPV NSView sits above the WebContents and is sized to the
viewport rect, so any DOM region it covers never receives pointer events.
Bundle 1 made the viewport fill the whole player, leaving no DOM strip to
catch pointermove — once the controls faded out there was no way to bring
them back via hover. Reapply the bottom inset on the viewport, scoped to
the slimmer 64 px panel, so the bottom strip is DOM-only and hover wakes
the controls. Swap the gradient for the glass surface treatment now that
the panel no longer needs to fade into video.

- Switch palette and surfaces to Material 3 tokens (--mat-sys-*) so the
player respects the app theme instead of a hardcoded cyan/sky scheme.
- Stop reserving 96 px below the viewport for the control panel; the panel
now floats over the bottom with a gradient fade so the video fills the
frame (especially in fullscreen).
- Drop control panel height from 96 to 64 px (88 px on narrow widths).
- Replace the corner "Loading stream in MPV..." pill with a centered
spinner + concise label during load; move the transient status toast
to the top-right and add role="status" aria-live.
- Add a red badge with pulsing dot for live streams in place of the plain
"LIVE" text label.
- Apply font-variant-numeric: tabular-nums to time/volume readouts so
digits stop jittering as playback advances.
- Slightly loosen transport/actions gaps for a less cramped rhythm and
use ease-out easing on control fade.

The embedded MPV player is a native NSView that sits above the WebContents
layer, so DOM dialogs (command palette, MatDialog, etc.) always paint behind
it regardless of z-index. Track CDK overlay backdrops via OverlayContainer +
MutationObserver and send off-screen bounds to the native view while any
backdrop is present, restoring real bounds on close. Playback continues
uninterrupted.

VLC was unconditionally spawned per click — VLC's own single-instance

Two small focused changes from an Angular perf audit.
content-card lazy loading
ContentCard is the building block for catalog grids and rails — Xtream
recently-added (3 rails × 20 = 60 cards on first paint), Xtream/Stalker
search results, unified favorites/recent grids. The poster <img> had
no loading attribute, so every off-screen card eagerly fetched its
poster from the Xtream/Stalker server on initial render. Same fix
already in place on the dashboard rail's separate <img>; mirror it on
the shared ContentCard so every consumer benefits.
Add loading="lazy" decoding="async" to both <img> tags (real poster
and the default-poster fallback). Browser defers off-screen requests;
no JS changes.
OnPush on workspace-sources-filters-panel
The sources filters panel renders one row per filter option and
displays {{ getTypeCount(option.id) }} per row — that method is a
plain Map lookup but fires every CD cycle under default change
detection. The component is signal-only (computed + selectSignal, no
subscribes) so the OnPush conversion is purely additive.

Three queries filter on categories.hidden = false:
- getGlobalRecentlyAdded — every dashboard load (now sorts by added DESC
on the indexed content side after the prior CAST removal)
- searchContent — Xtream search with excludeHidden
- globalSearch — global Xtream search with excludeHidden
All three start from content and join into categories on the
category_id PK. The hidden filter is then applied per-row, requiring a
row lookup for every result candidate — even before LIMIT.
Add a partial covering index on categories: idx_categories_visible(id,
playlist_id, type) WHERE hidden = 0. Two wins:
- Covering: SQLite serves the join (id) plus filters (playlist_id,
type) and the hidden = 0 predicate directly from the index without
ever touching the categories row.
- Partial: hidden categories are absent from the index, so they're
pruned before any work happens — no row lookup, no comparison.
Schema mirrored in Drizzle so the ORM stays the single source of
truth. CREATE INDEX IF NOT EXISTS so existing DBs pick it up on next
startup with no migration needed.

Two compounding wins for the dashboard's M3U favorites path.
#3 — Memoize loadM3uPlaylistFavorites
The function calls getPlaylistById() which deserializes the entire
M3U playlist payload (potentially 90K channels) just to read the
favorites field and the matching items. On every dashboard mount, it
re-paid that cost for every M3U playlist with favorites — even though
nothing relevant had changed.
Add a per-playlist cache keyed by playlist ID with a fingerprint of
{updateDate, favorites JSON}. A cache hit skips the heavyweight
playlist read entirely; a refresh (updateDate change) or favorites
add/remove naturally invalidates without explicit busting. First
mount still pays the parse; subsequent dashboard visits and
re-renders are effectively free.
#4 — Stream per-playlist favorites into the rail
reloadM3uGlobalFavorites used Promise.all over loadM3uPlaylistFavorites
and wrote one flat array at the end, so a single slow M3U playlist
pinned the entire M3U favorites contribution behind it.
Replace the writable m3uGlobalFavorites signal-of-array with a
WritableSignal<Map<playlistId, items[]>> + computed flatten. Each
playlist's contribution lands in the map as soon as ITS load resolves
(usually instant via the new cache), so the favorites rail re-renders
incrementally — Xtream favorites first, then each M3U playlist's
favorites appear as it streams in.
Cache + map entries for playlists that no longer have favorites are
pruned at the start of each reload, so removed playlists don't leave
stale state.

Two independent fixes that compound: the dashboard now renders progressively
as each rail's data resolves, and the slowest of those rails (Xtream
recently-added) no longer scans the entire content table.
Per-rail skeletons (template restructure):
The old @if (!ready()) gate hid the whole dashboard until ALL FOUR loading
flags resolved (playlistsLoaded, globalRecentLoaded, globalFavoritesLoaded,
xtreamRecentlyAddedLoaded). The slowest one pinned the entire skeleton up
for the full tail latency — visibly seconds of "loading" even when 3 of 4
rails could have rendered immediately.
Replace with per-rail conditionals:
- Hero: renders the moment globalRecentItems[0] is available; skeleton
shows only while data.globalRecentLoading() is true and no item exists.
- Each rail: shows real content if its cards are non-empty, its own
skeleton if its dedicated loading flag is true, nothing otherwise.
- The Xtream recently-added rail's skeleton is gated on having Xtream
playlists at all, so M3U-only users never see a skeleton for it.
The loading signals were already exposed on DashboardDataService
(globalRecentLoading, globalFavoritesLoading, xtreamRecentlyAddedLoading)
but went unused because of the monolithic gate. Same skeleton markup is
reused per rail; no styling changes.
Drop CAST(added AS INTEGER) in getGlobalRecentlyAdded:
The query ordered by sql<number>\`CAST(content.added AS INTEGER)\`. SQLite
cannot use an index on a column wrapped in a function, so the existing
idx_content_type_added index was bypassed and the planner did a full table
scan + sort on content (10k–100k+ rows for a typical Xtream catalog) on
every dashboard load.
Sort by schema.content.added directly. Xtream stores Unix-epoch timestamps
as 10-digit numeric strings (anything since 2001-09-09), so lexicographic
and numeric sort are equivalent. The (type, added) index now drives the
ORDER BY too — full table scan becomes an index range scan + LIMIT 20.

PortalStatusService previously did one IPC + HTTPS round-trip per call,
forcing every consumer to roll its own cache (or, more often, not).
The result: opening the homepage rendered N playlist-item components
that each fired their own check, then opening the playlist switcher
fired N more for the same portals.
Move the cache and dedup into the service:
- 30 s TTL cache keyed by `${serverUrl}|${username}|${password}`. Same
credentials = same cache entry, regardless of which playlist row
triggered it.
- In-flight dedup via Map<key, Promise<PortalStatus>>. Two callers
hitting the same portal in the same tick share one network request
instead of racing.
- New `getCachedStatus()` for sync read (used by playlist-switcher to
hydrate the UI on menu open without awaiting).
- New `clearStatusCache()` for log-out / debug flows.
Add `{ skipCache: true }` opt-out for the Xtream import dialog's
"Test Connection" button — that's a user-initiated check that must
return fresh truth, not a 30 s old cached result.
Net result: in the common flow (homepage → switcher), the switcher
opens with cached status indicators instantly. The single in-flight
dedup prevents the playlist-item ngOnInit + switcher onMenuOpened from
racing for the same portal.
Removed the component-local cache from playlist-switcher; service is
now the single source of truth.

The loading placeholders for live channel rows were inconsistent and
visibly heavier than the real channel-list-item: each module rendered
its own skeleton with a colored card surface, larger padding/radius,
mismatched logo border-radius, and only a single tiny right-side dot
instead of the real 34×34 action buttons. Stalker had no initial-load
skeleton at all.
Extract a shared app-channel-list-item-skeleton that mirrors
channel-list-item 1:1 (transparent surface, 8/10/8/12 padding, 12px
radius, 44×44 logo with 10px radius, optional EPG progress placeholder,
0–3 button placeholders) plus a thin app-channel-list-skeleton wrapper
that renders N rows with deterministic width variance, and route every
live-tv loading state through it (m3u channel-list-loading-state,
xtream portal-channels-list, stalker live-stream-layout via a derived
isInitialChannelsLoading signal, and the unified favorites/recent
collection page). Drops the bespoke channel-skeleton-shimmer keyframes
