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

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

Opening the playlist switcher fired one XTREAM_REQUEST IPC + HTTPS
round-trip per Xtream playlist and only updated the UI after ALL of
them resolved. A single slow or hung portal pinned every status dot
in the menu to the misleading red 'unavailable' state for the full
tail latency (often several seconds, sometimes longer).
Four changes land together:
1. Stream results — each portal's dot updates via signal.update() the
moment ITS request resolves, independent of the slowest one. The
previous Promise.all wrote a single Map at the end; now the Map
grows incrementally.
2. New 'checking' status — extends PortalStatus with a pulsing-dot
visual so users see "we're working on it" instead of red dots
that look like failures. Respects prefers-reduced-motion.
3. 30-second TTL cache — opening, closing, and reopening the menu
within 30s reuses prior status results and skips the IPC entirely.
Cache survives across menu opens but is per-component instance
(a global cache is a possible follow-up).
4. AbortController cancellation — closing the menu (or destroying the
component) cancels in-flight checks so a slow portal can't write
stale results into the next round. Solves the 'rapidly open/close
the menu and watch dots flicker' problem.
The actual IPC layer wasn't changed — the wins come purely from
streaming, caching, and not lying to the user about portal state.

The three channel-list views (all-channels, groups, favorites) each had
an enrichedXxx computed signal that, on every progressTick (~30 s),
spread-cloned every channel in scope to attach { epgProgram, logo,
progressPercentage }. On a 90 K-channel M3U playlist, all-channels-view
allocated ~90 K objects per tick — persistent young-gen pressure and
visible GC stutter on large lists.
Replace the pattern with a side-car ChannelEpgMetadata map keyed by EPG
lookup key, holding only entries for channels that actually have EPG
data (typically a small fraction of the playlist). Templates iterate
the raw channel array and look up { epgProgram, progressPercentage }
inline. Logo resolution moves to a per-row method call — under OnPush
+ virtual scroll only ~50 visible rows check at a time.
groups-view's selectedGroupChannels also lost its progressTick
dependency: sorting + filtering only reruns when the selected group or
sort mode changes, no longer every 30 s.
The EnrichedChannel interface is replaced with a smaller
ChannelEpgMetadata. Specs that asserted on the cloned `.logo` field now
call `getLogoForChannel(channel)`.
Inspired by matracey/iptvnator@8d78cc0, @b9e6e82, @296d61e — ported as

Channel-list rendering called EpgService.getCurrentProgramsForChannels(),
which forkJoined N getChannelPrograms() Observables — each firing its own
IPC round-trip and its own SQL query. For a 500-channel visible window on
first scroll, that was 500 IPC calls and 500 SELECTs hammering the EPG
table.
Add GET_CURRENT_PROGRAMS_BATCH IPC handler that takes the channel-id
array and runs a single SELECT with WHERE channel_id IN (...) AND
start <= now AND stop >= now. The renderer-side cache and TTL behavior
are preserved; only the network of IPC calls collapses to one. A
fallback path keeps the old per-channel behavior if the preload lacks
the new endpoint.
Per-channel display-name fallback (NOCASE id, then NOCASE display name)
is preserved from handleGetChannelPrograms so behavior matches the
existing single-channel handler.

Three placeholders were rendering at once when a search filter cleared
both the groups rail and the channel list, and they each used a
different visual treatment:
1. Groups rail (.groups-nav-empty) was bare 0.82rem muted text with no
icon and no hint, and routed through CHANNELS.NO_SEARCH_RESULTS
("No channels found") which is wrong copy for the *groups* column.
2. Channel list (.groups-content-empty-state) was the canonical L4
icon + title + hint pattern (correct).
3. Player area (<app-portal-empty-state>) was a 72px icon at 0.2
opacity, which read as ghosted on dark theme.
Bring the groups rail into the L4 family scaled down for the narrow
column: 28px search_off / folder_off icon at 0.5 opacity, 0.85rem
title, 0.78rem hint at 0.65 opacity, centered. Add a CHANNELS.NO_GROUPS_FOUND
i18n key so the copy reflects the column ("No groups found").

opacity from 0.5 -> 0.6 so the player-area placeholder feels present

Drop the .empty-icon-wrapper tile, switch to the canonical sizes, and

excluded everything.
grid-list now takes a searchTerm input and branches the @empty fallback:
when a search is active it renders the NO_SEARCH_RESULTS view with the
parameterised "No results found for {term}" title, otherwise it falls
back to EMPTY_CATEGORY as before. category-content-view derives the
searchTerm signal from the ?q= query param and passes it through.
Also: bump the NO_SEARCH_RESULTS icon from a 64px mat-icon to a clamp()
sized icon (120-180px) at 0.5 opacity so it visually balances with the
SVG illustrations used by the other viewTypes, swap the icon to
search_off (struck-through magnifier) so it reads as "no results"
rather than "search now", and fix the EN i18n typo
("change you search request" -> "change your search request").

iptv-playlist-parser statically imports the entire validator library
(~130KB across 113 files). Because PlaylistsService is eager (re-exported
through the 'services' barrel that AppComponent imports), validator was
landing in the cold-start preloaded chunk even though parse() only runs
on user-triggered playlist imports (FILE/URL/TEXT add).
Switch handlePlaylistParsing() to dynamic-import the parser. The two
callers (playlist-backup.service and the parsePlaylist$ NgRx effect)
needed minor adjustments — the effect now uses mergeMap(from(...)) to
flatten the Promise back into the action stream.
Cold-start preloaded chunk: 1511KB -> 1374KB (-9%).
Validator now sits in a separate ~129KB chunk that loads only when
the user adds a playlist.

Clearing all recents of a given content type fired N concurrent IPC calls,
each opening its own implicit transaction in the recently_viewed table.
For users with hundreds of recently-watched VOD/series rows this added
real overhead even though the UI updates optimistically.
Add a new DB_REMOVE_RECENT_ITEMS_BATCH path end-to-end:
- removeRecentItemsBatch() Drizzle op: one transaction, one prepared
statement reused per row
- Wire through worker → IPC handler → preload → window.electron typings
→ DatabaseService
- UnifiedRecentDataService.removeRecentItemsBatch() groups items by
source. Xtream items go through the new batch IPC. M3U/Stalker items
still go per-playlist because they update a JSON column on the
playlist row, not the recently_viewed table — but they now run in
parallel with the Xtream batch via a single Promise.all.
- Single call site updated: unified-collection-page "Clear all of type"
confirmation handler.

Replace the dashed-bordered "Ooops" placeholder in the EPG side panel
(rendered when the selected date has no programmes) with the icon +
title + hint pattern already used by groups view, season container,
and portal empty states.
The dashed border was a visual outlier — every other empty state in
the codebase is borderless, and a dashed stroke conventionally signals
a drop-zone or "add new" affordance, neither of which applies to a
passive informational state. The new layout uses a 48px event_busy
icon at 0.5 opacity, a 1.05rem title, and a 0.85rem hint at 0.65
opacity, centered in the panel via flex.
Soften the EN microcopy ("Ooops, EPG is not available for the selected
date" -> "No program guide", which also fixes the "Ooops" typo) and
add a NO_GUIDE_HINT key with localized strings across all 18 locales,
nudging the user toward the date arrows or playlist refresh.

PortalChannelsListComponent renders a virtual-scrolled channel list (Xtream
live/VOD/series, can be 1000+ items). It was using default change detection,
so every CD cycle in the parent tree (EPG ticks, progress updates) re-checked
every binding. Switch to OnPush — the existing cdr.detectChanges() calls
already cover the async update paths, and signal-based state marks for check
automatically.
Replace track $index with track program.start in two EPG @for loops
(epg-list, multi-epg-container search results). $index causes Angular to
re-create DOM nodes whenever the list reorders (e.g. on EPG refresh or
timezone correction). program.start is the ISO datetime — unique per
program within a channel and stable.

The existing single-column indexes force a sort step for the most common
list queries. These three composite indexes let SQLite scan in index
order and skip the sort entirely:
- recently_viewed(playlist_id, viewed_at DESC):
getRecentItems(): WHERE playlist_id = ? ORDER BY viewed_at DESC LIMIT 100
- favorites(playlist_id, position, added_at DESC):
getFavorites/getGlobalFavorites/getAllGlobalFavorites():
WHERE playlist_id = ? ORDER BY position ASC, added_at DESC
- playback_positions(playlist_id, updated_at DESC):
getRecentPlaybackPositions(): WHERE playlist_id = ? ORDER BY updated_at DESC LIMIT 20
CREATE INDEX IF NOT EXISTS so existing DBs pick up the new indexes on
next startup with no migration required. Mirrored in the Drizzle schema
using sql\`col DESC\` so the ORM stays the source of truth.

SQLite's recommended approach for keeping query plans current: cheap when
nothing needs analyzing, runs incremental ANALYZE on tables/indexes that
have grown significantly since the last run. Wrapped in try/catch since
optimize is advisory and must never block connection close.
Applied to both the main connection and the EPG worker connection.

Pair the existing journal_mode=WAL with the companion pragmas it needs to
actually pay off, and reduce read latency on hot query paths.
- synchronous=NORMAL: ~2-10x faster writes when paired with WAL. Safe — only
risks losing the last committed txn on power loss; DB stays consistent.
- cache_size=-64000: 64MB page cache (default is 2MB).
- temp_store=MEMORY: keep sort/group temp tables in RAM.
- mmap_size=268435456: 256MB memory-mapped I/O for reads.
Applied to both connection sites: the main read-write/read-only connection
in libs/shared/database and the EPG worker connection in electron-backend.
The per-connection pragmas (cache_size, temp_store, mmap_size) apply to the
read-only agent-backend connection too.
Inspired by matracey/iptvnator@4ad8f88; ported manually since the file has
diverged significantly and the worker connection didn't exist in that fork.

The two component specs in this lib had been carrying 7 long-standing
failures rooted in three stale-mock issues, all unrelated to public
behaviour but enough to make the suite red on every run.
Header spec (5 failures, NG0303 on app-playlist-switcher):
- MockPlaylistSwitcherComponent was missing canRefreshActivePlaylist /
isRefreshingActivePlaylist inputs and refreshPlaylistRequested
output. The real PlaylistSwitcherComponent grew them when refresh
was added to the header; the mock never caught up. Re-aligned.
Workspace-shell component spec (2 failures):
- NG0301 on #dropZone="playlistDropZone" because overrideComponent's
set.imports list dropped PlaylistDropZoneDirective and the drop
overlay component. Added MockPlaylistDropZoneDirective and
MockPlaylistDropOverlayComponent.
- After the recent option-D refactor that lifted the import overlay
into its own child component, the spec also needed
MockWorkspaceShellImportOverlayComponent so the parent template
could resolve <app-workspace-shell-import-overlay />.
- MockWorkspaceShellHeaderComponent gained hasNoPlaylists input and
MockWorkspaceShellContextSidebarComponent gained hasPlaylists input
to match the real components.
- The "renders type-aware xtream import progress copy" test asserted
on inline overlay markup that no longer lives in the parent
template. Replaced with a structural test that the overlay child
renders/unmounts based on facade.showXtreamImportOverlay().
New focused spec for WorkspaceShellImportOverlayComponent (6 tests)
covers the moved progress-copy assertion at the right level by mocking
the WorkspaceShellXtreamImportService directly: title, progress copy,
determinate vs indeterminate progress bar, badge tone, and cancel
forwarding.
Final state: full feature lib suite is 66/66 (was 53/60 with 7
chronic failures). pnpm nx test web, pnpm nx lint
workspace-shell-feature, pnpm nx build web --configuration=production,
and the basic + settings web-e2e suites all pass.

Continues the workspace-shell facade decomposition by relocating two
clusters from the parent template into the components that own them.
Xtream import overlay:
- New WorkspaceShellImportOverlayComponent injects
WorkspaceShellXtreamImportService directly. The 70-line inline
overlay block in workspace-shell.component.html collapses to a
single <app-workspace-shell-import-overlay /> element, gated by
facade.showXtreamImportOverlay().
- Overlay-specific styles move from workspace-shell.component.scss
into the child component (~125 lines relocated).
- Facade drops 14 import re-export lines plus the cancelXtreamImport
delegation. The two facade tests that exercised label generation
now resolve the service via TestBed.inject and assert against it
directly.
Header bulk action:
- WorkspaceShellHeaderComponent gains headerBulkAction input and
headerBulkActionRequested output, plus a button that renders the
action when present (next to the existing headerShortcut button).
- The parent template wires facade.headerBulkAction() →
facade.runHeaderBulkAction(). The facade keeps the cross-cutting
computed and the multi-store dispatch method since both span
multiple stores.
Verification:
- workspace-shell.facade.spec.ts: 20/20 passing (two assertions
retargeted at WorkspaceShellXtreamImportService).
- Full feature lib: 53/60 passing — same 7 pre-existing failures.
- pnpm nx build web --configuration=production: success.
- pnpm nx lint workspace-shell-feature: clean.
- pnpm nx run web-e2e:e2e-ci--src/basic.e2e.ts: 3/3 across browsers.
- pnpm nx run web-e2e:e2e-ci--src/settings.e2e.ts: 12/12 across
browsers.
Facade: 917 → 897 lines. The bulk-action button now actually renders
in the header — closing a latent gap where the computed existed on
the facade but had no template binding.

Production build (stricter than test/dev) flagged the helper signature
as requiring a mutable array while WorkspaceViewCommandService.commands
returns readonly. The body uses spread, so widening the parameter to
readonly is the correct fix and unblocks `nx build web` plus E2E.

The WorkspaceShellFacade had grown to 1666 lines, well past the 300/400
LOC target in CLAUDE.md. The component template binds to 54 facade
members directly, so the split preserves the public API by reference
re-export and keeps the template untouched.
Phase 1 — extract pure helpers (no DI, no behavior change):
- helpers/workspace-shell-constants.ts: i18n keys, RAIL_TOOLTIP_KEYS,
XtreamImportPhaseTone, WorkspaceHeaderBulkAction
- helpers/workspace-shell-route-utils.ts: toQueryString,
getRouteQueryParam, syncSearchQueryParam, bumpRefreshQueryParam,
getProviderFromPlaylist
- helpers/workspace-shell-search-labels.ts: resolveSearchPlaceholderKey,
resolveSearchScopeLabel, resolveActiveCategoryLabel, getRailTooltipKey,
translateRailLinks (each takes TranslateFn + snapshots as params)
- helpers/workspace-shell-import-labels.ts: build* helpers for the 14
Xtream import overlay labels and formatLocalizedNumber
- helpers/workspace-shell-command-builders.ts: buildCommandPaletteItems
plus the three command-definition builders, navigation command
factory, resolveCommand, comparePaletteCommands, getCommandGroupOrder
Phase 2 — extract the two component-scoped sub-services with the
cleanest boundaries:
- WorkspaceShellXtreamImportService: read-only labels, cancel action,
isImportRunning. Reads only XtreamStore + TranslateService.
- WorkspaceShellCommandPaletteService: MatDialog lifecycle, recent
commands integration, eager WorkspacePlayerCommandsContributor
bootstrap. Receives a typed CommandBuilderContext via function
argument from the parent — no circular DI.
The parent facade re-exposes every member by reference assignment so
signal identity is preserved for change detection. workspace-shell.
component.html is unchanged. workspace-shell.component.ts gains only
two provider entries for the new sub-services.
Verification:
- workspace-shell.facade.spec.ts: 20/20 passing
- pnpm nx lint workspace-shell-feature: clean
- workspace-shell-feature suite: 53/60 passing — same 7 pre-existing
failures (header & shell component specs hit unrelated NG0301
on playlistDropZone export); no regressions introduced
- CDP smoke: command palette opens with Recently Used + Global
Actions groups, settings nav disables search bar correctly
Facade reduces from 1666 to 917 lines. Each new helper/service is
under 250 lines except command-builders.ts (462) which is mostly
declarative command definitions. The parent facade is still over the
400-line hard max because cross-cutting orchestration
(searchCapability, runHeaderBulkAction, rail link computeds) reads
from multiple clusters; further reduction would require moving logic
into child components, which is deferred per the plan.
Plan: ~/.claude/plans/workspace-shell-facade-ts-is-now-1668-crispy-planet.md
(also copied locally to .plans/2026-05-01-workspace-shell-facade-split.md;
the working-tree .gitignore change excludes .plans from tracking).
