d61fd5db19 feat: add strip country prefix setting (#1162)
* feat: add strip country prefix setting

* feat: scope country-prefix stripping to live content and cover missing surfaces

- narrow the heuristic: pipes always strip, dash/colon separators only
  when the prefix is a short uppercase tag ("UK - BBC One" strips,
  "Sky - Sports F1" and "Mission: Impossible - Fallout" stay intact)
- fall back to the original name when stripping would leave nothing
- scope stripping to live content only: grid type (live/itv/radio),
  playback isLive, external sessions without contentInfo, dashboard
  cards with contentType 'live'
- cover previously missed surfaces: M3U player EPG timeline header,
  M3U inline player title, radio player, dashboard live rails
- replace hardcoded settings strings with translate keys and add
  SETTINGS.STRIP_COUNTRY_PREFIX(_DESCRIPTION) to all 18 locales
- add unit specs for the utility plus regression specs for
  channel-list-item and external-playback-dock

* test: cover strip-country-prefix call sites for codecov

- dashboard-rail: new spec for cardTitle live/movie/series scoping
- grid-list: strip enabled/disabled, VOD passthrough, 'No name' fallback
- portal-inline-player: live strip vs VOD passthrough
- unified-live-tab: timeline channel name strip + M3U name precedence
- video-player: timeline/radio/inline titles with the setting on and off
- settings-store: default false + persisted true round-trip
- settings-form.utils: new spec for form default and ?? false fallback

4grayandClaude Fable 5 1c710d69ef chore(cleanup): delete nine dead components, orphaned i18n keys and unused deps (#1116)
* chore(cleanup): delete nine dead components, orphaned i18n keys and unused deps

Removes verified-dead components (0 class/selector references outside
their own files): EpgListComponent (+ epg-list-item), EpgViewComponent,
LiveEpgPanelComponent, StalkerCollectionChannelsListComponent,
NavigationComponent, FilterSortMenuComponent, video-player
ToolbarComponent, PortalCollectionShellComponent and
LoadingOverlayComponent, together with their barrel exports.

Alive code extracted from the deleted trees:
- LiveEpgPanelSummary -> libs/ui/shared-portals/src/lib/live-epg-panel-summary.ts
- EpgProgramActivationEvent -> libs/ui/epg/src/lib/epg-program-activation-event.ts
- epg-list.utils.ts trimmed to the three timeline-used helpers and moved
  to libs/ui/epg/src/lib/epg-program.utils.ts
- epg-item-description/ moved up out of the deleted epg-list/ folder

Also removes 18 i18n keys now unused (from all 18 locales), dead CSS
selectors targeting the deleted elements, and unused dependencies:
lodash (+ @types/lodash), semver, @ngrx/component-store and
@videojs/http-streaming (videojs-quality-selector-hls declares no peer
dependency on it; video.js 8 bundles VHS).

* chore(coverage): move shared-portals to Tier C, fix stale doc references

The Tier A gate failed in CI because deleting the dead epg-view and
live-epg-panel components removed the only specs in libs/ui/shared-portals.
The lib now contains a single type-only interface (LiveEpgPanelSummary),
so there is no runtime code to unit test; reclassify it to Tier C with a
documented reason, matching the gate's own guidance.

Also update remaining doc references to the deleted components in
docs/architecture/stalker-epg.md, iptvnator-ui-guidelines.md and
CLAUDE.md.

4grayandClaude Opus 4.8 0b526b119a feat(epg): add vertical list view for the live EPG panel (#1115)
* feat(epg): add vertical list view for the live EPG panel

Add an EPG list view — a vertical, single-day programme list — as an
alternative rendering of the live EPG panel, selectable via a new
Settings → EPG → "Guide view" toggle (epgViewMode: 'timeline' | 'list',
default 'timeline' so existing users see no change).

- New EpgListViewComponent (app-epg-list-view) mirrors
  EpgTimelineComponent's input/output contract 1:1, so all four live
  hosts (M3U player, unified live tab, Xtream, Stalker) swap the panel
  with a plain @if and identical bindings.
- Reuses the shared view-agnostic EPG modules (classifyTimelineWhen,
  hasProgramsForDateKey, epg-archive.util catch-up gating,
  epg-summary.util collapsed-summary maths, epg-date helpers,
  EpgProgrammeDialogService, app-epg-timeline-empty-state) — no
  duplicated logic.
- Rows show time range, title, optional description, live progress on
  the on-air row, catch-up "Watch" on past rows when archive playback
  is available, and a details dialog; keyboard activation guards
  nested buttons (target === currentTarget).
- Auto-focuses the on-air row on channel select, restores it across
  collapse/expand remounts, and shows a sticky in-flow "On now" strip
  (never overlaying rows) when the current programme is scrolled away;
  all scroll maths is rect-based relative to the scroller.
- List mode raises only the inline panel height via an epg--list
  modifier (--epg-inline-height clamp); timeline and collapsed heights
  are unchanged.
- Setting flows end-to-end (Settings interface → DEFAULT_SETTINGS →
  SettingsStore/StorageMap → segmented control in the EPG section);
  Electron-only UI, PWA stays on the timeline default. i18n keys added
  to all 18 locales.
- Tests: new component/row/utils/scroll-controller specs, settings
  persistence spec, swap tests in all four host specs, and Electron
  E2E for the settings round-trip and the rendered list view. Docs
  updated (m3u-playlist-module.md).

* fix(epg): address list-view review findings from Codex and Greptile

- Reset the list view to today when a new channel's programme set
  arrives while the user is parked on another day (timeline parity):
  the scroll controller now keys by the full programme-set identity
  (programsFocusKey) and commits today before focusing, instead of
  silently stranding the new channel on the stale day. (Codex P2)
- Centralise the 'timeline' fallback as a resolvedEpgViewMode computed
  on SettingsStore; the four live hosts consume the derived signal
  instead of duplicating the `?? 'timeline'` expression. (Greptile P2)
- Extract the component's reactive plumbing into
  registerEpgListViewEffects(), bringing the component back under the
  300-line guideline (290). (Greptile P2)
- Controller spec rewritten around programme-set fixtures with new
  coverage: return-to-today on channel switch, day navigation left
  alone, no-takeover when today has no data, empty-set no-op.

* fix(epg): drop malformed programmes from the list-view day filter

Reject programmes whose stop is not after their start in
buildEpgListRows — same as the timeline's buildTimelineBlocks. Bad
provider data would otherwise render impossible time ranges and could
even be offered as catch-up playable. (Codex P2 on e6fd0d08)

4gray 401012eac4 feat(epg): rework live EPG panel into a horizontal timeline (#1102)
Replaces the vertical EPG list with a shared horizontal `app-epg-timeline`
ribbon across all live surfaces (M3U player, unified live tab, Xtream, Stalker):
zoom, day navigation, short-programme grouping, catch-up/timeshift, and
per-state empty views. Backend gains timezone-aware `datetime()` comparisons,
unscoped source fallback, non-ASCII candidate matching, and chunked candidate
queries.

Timeline split into reusable, view-agnostic modules (archive/summary/dialog
service/render util/scroll controller) for the future EPG list view.

Fixes landed during review:
- honor the controlled `selectedDate` input (seed via linkedSignal)
- restore ribbon position across collapse/expand
- keep the ribbon mounted when scrolling across a gap day
- don't trigger block playback on Enter from nested watch/info buttons
- don't reset timeshift playback on the 30s now-tick during EPG gaps

Greptile 5/5 (safe to merge); Codex clean; CI green.

fix(m3u): highlight active archive epg program

* Store the active archive EPG program with the resolved playback URL so the clicked M3U catch-up row stays highlighted during archive playback.
* Show archive playback state and return-to-live controls in the inline player panel.

4grayandClaude Opus 4.7 d59fa74650 fix(add-playlist): align dialog head with content padding
The custom .apd-head was getting visually orphaned from the rest of the
dialog body: zero horizontal padding so the title sat flush against the
dialog edge (cards inside mat-dialog-content are inset by 24px), plus a
~44px vertical gap above the title even though the head reported
padding: 0.

The gap was Material's .mdc-dialog__title::before — a 40px-tall
invisible inline element used to baseline-align dialog titles to a
grid. Useful for single-line titles, hostile to a two-line head with
explicit subtitle.

Set .apd-head padding to 20px 24px 4px so it shares the dialog
content's 24px horizontal rhythm, then suppress the ::before ghost.
Title now sits 20px from the dialog top edge with the same left inset
as the method cards and the form fields below.

4grayandClaude Opus 4.7 810d9170f0 fix(add-playlist): widen dialog and use card-friendly labels
The 5-card method picker was rendering at the old 560px dialog width
which left each card too narrow — titles wrapped to 2-3 lines and the
subtitles to 6, all visible in the user-reported screenshot.

Three fixes:

1. Bump the dialog width from 560px → 780px to match the v0.22 mockup.
   maxWidth: 92vw keeps the responsive collapse path intact.

2. Replace the inherited "Add via URL" / "Add via file upload" /
   "Add Xtreme Code" / "Add Stalker Portal" / "Import from text" tab
   labels with short noun-only card titles: "M3U URL", "M3U file",
   "Xtream credentials", "Stalker portal", "Raw m3u text". The dialog
   itself is titled "Add playlist" so the "Add" prefix on every card
   was redundant. The "Xtreme" misspelling on the old key disappears
   as a side effect.

3. Lock cards to min-height: 132px so the URL card (short subtitle)
   stops collapsing while the Xtream/Stalker cards (longer subtitle)
   stretch — selection states now look visually consistent. Slightly
   tighter padding (10/11/12 vs 12/14) to fit the new width without
   feeling cramped.

i18n: 5 new METHOD_*_LABEL keys translated across all 17 locales by
per-locale agents; placeholder integrity verified across all 920+
leaf keys.

4grayandClaude Opus 4.7 210baa2e75 refactor(add-playlist): replace 2-level type×subtype with flat 5-card picker
The Add Playlist dialog used a nested control: pick category
(M3U / Xtream / Stalker) then pick subtype (URL / file / text). That's
9 cells of which only 5 are real — Xtream-via-file and Stalker-via-text
don't exist. Users spent visible time hunting the right path through
the matrix.

Replace it with a flat 5-card method grid that matches the v0.22 mockup
exactly: each card IS a method (M3U URL, M3U file, Xtream credentials,
Stalker portal, Paste raw m3u text), shown side by side with an icon,
label, and one-line description of when to pick it.

Component state collapses from `category` + `m3uSubType` (two signals
with an entangled `playlistType()` mapping) into a single `method`
signal of type PlaylistType. `initFromType` simplifies to one line.
`playlistType()` is kept as a thin alias so the template @switch and
the action-button branches stay untouched.

The selected card is the only place that needs to change for users to
pick a different method — no more "first click type, then click
subtype, then look for the form" two-step.

i18n: 6 new HOME.ADD_PLAYLIST.* keys (subtitle + 5 method subs)
translated across all 17 locales by per-locale agents, with the
existing HOME.TABS.* keys reused for card titles. Placeholder
integrity verified.

Tests: existing clearCurrentForm scenarios still pass after the signal
refactor; added 6 new tests covering the default method (URL) and the
MAT_DIALOG_DATA.type deep-link path for each of the 5 method values.

4grayandClaude Opus 4.7 a27a29fcf2 refactor(ui): unify primary color to blue across all surfaces
Swap M3 primary palette from violet to azure so checkboxes, radio
buttons, raised CTAs, and active states read as the same blue used by
the rail selection token. Cascading template + SCSS updates align the
remaining hand-rolled surfaces (Add Playlist dialog, VOD play button,
radio player, multi-EPG, empty-state CTAs) with the unified system.

LIVE stays red (broadcast role), cyan stays on EPG "now" indicator,
green stays on completed-download — semantic colors keep their meaning;
only the indiscriminate accent uses get folded into the blue primary.

4grayandClaude Opus 4.7 880163ca7a perf(portal-status): hoist 30s TTL cache + in-flight dedup into shared service
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.

4grayandClaude Opus 4.7 888a2dd80a perf(playlist-switcher): stream Xtream portal status checks instead of blocking on Promise.all
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.

4grayandClaude Opus 4.7 2f7406054d perf(ui): enable OnPush across hot list-rendering components
Audit found 10 list-rendering components (each >150 lines, all using
signal-based state) on default change detection. Default CD re-checks
every binding on every parent CD cycle (mouse moves, EPG progress
ticks, etc.); under OnPush these only re-check when their own signals
change or when explicitly markedForCheck.

All 10 use signals exclusively for state (no manual subscribe-and-mutate
patterns), so the conversion is straightforward and safe.

Components:
- recent-playlists (740L) — homepage playlist list with drag-drop
- vod-details-route (552L) — Xtream VOD detail page
- playlist-switcher (509L) — workspace shell playlist switcher
- season-container (444L) — Stalker/Xtream series episodes (DoCheck preserved)
- stalker-search (362L) — Stalker search results
- search-results (350L) — Xtream search results
- category-management-dialog (199L) — manage Xtream categories
- recently-added (162L) — Xtream recently-added rail
- category-content-view (Catalog) — category browse page
- grid-list (shared) — generic grid renderer used across portals

Tests: 124 passed across all touched lib projects.

4gray 9f873e6bed feat(player): add embedded-mpv player for macOS as experimental feature
- Introduced tooling for building and staging the macOS `libmpv` runtime for IPTVnator's embedded MPV player.
- Added `build-macos-runtime.mjs` for building an LGPL-compatible runtime from source.

- Implemented validation for the packaged embedded MPV runtime in `electron-after-pack.cjs` and `embedded-mpv-macos.cjs`.
- Updated packaging scripts to ensure the embedded MPV runtime is correctly integrated and validated during the build process.
- Added README files to document the expected layout and usage for the embedded MPV runtime artifacts.
