Adds a paused state to the Electron download manager with a full partial-file lifecycle:
- Pause keeps the .part and byte progress; cancel discards them; every lifecycle stage (queued, active, mid-transfer) is pausable.
- Resume continues via HTTP Range with If-Range entity validation (strong ETag / Last-Modified persisted in the new resume_validator column, idempotent migration incl. legacy-table rebuild). Non-206 answers restart from zero over the same .part; the 206 Content-Range offset is verified; responses that end before the advertised size are retained for a Range retry instead of being committed as completed.
- Crash recovery converts interrupted transfers to paused, keeps queued-with-partial rows resumable, and commits finalizations that crashed before the DB update.
- Destination collisions are non-destructive (retained partials finalize to the next numbered name); locked .part files never lose their DB owner across cancel/remove/restart; resume claims rows atomically and the queue dedupes ids.
- Stored request headers are re-filtered through the User-Agent/Origin/Referer allowlist on read, URL-derived extensions are sanitized, resume appends never follow symlinks, and transfer errors are logged by message only.
- UI: pause/resume/cancel/retry/remove surface failures in a snackbar; paused items show an active Resume button in VOD/episode detail views; translations for all 18 locales.
- Runtime split into download-runtime/transfer/finalize/broadcast modules; +30 unit tests and an Electron E2E covering pause -> retained .part -> Range/If-Range resume -> byte-exact assembly.

* fix(security): harden Electron IPC against MITM, SSRF, path and injection risks
S1 TLS: validate certs by default on playlist/EPG fetches (opt-out via IPTVNATOR_ALLOW_INSECURE_TLS); new util/secure-https.ts.
S2: write-file IPC restricted to save-dialog-authorized paths.
S3: XTREAM_PROBE_URL guarded by assertRemoteUrlAllowed + maxRedirects:0; new events/url-safety.ts (+19 tests).
S4: EPG titles rendered via interpolation, not [innerHTML].
S5: downloads reveal/play limited to recorded download paths.
S6: Stalker cmd encoded (slash-preserving) to block query injection.
EPG-worker and Stalker fetches reject file://-style/credentialed URLs; LAN/self-hosted targets remain allowed.
* perf(player): lazy-load web video players via @defer
Wrap Video.js/HTML5/ArtPlayer in @defer (on immediate) so video.js, hls.js,
artplayer and mpegts.js split into a deferred chunk loaded on first playback
instead of eagerly on the player route. Embedded MPV (native) stays eager.
Spec uses DeferBlockBehavior.Playthrough.
* fix(player): remove leaked HTML video listeners on destroy
volumechange used a mismatched removeEventListener reference, while
loadedmetadata and timeupdate were never removed at all. Bind all three to
stable handler fields used for both add and remove, and add a teardown
regression test asserting each listener is detached on destroy.
* refactor(dashboard): extract pure navigation helpers from DashboardDataService
Move the 8 stateless link/navigation-state/type-kind helpers into a new
dashboard-navigation.util.ts so the routing logic is independently testable and
the 1260-line god-service shrinks. DashboardDataService keeps the public methods
as thin delegators (facade) so the public API and the single consumer
(workspace-dashboard-rails) are unchanged. First slice of the DashboardDataService
decomposition; verified by the existing service spec (33/33) and the app typecheck.
* fix(review): address PR feedback (IPv6 link-local, write-path cap, @defer placeholder)
- url-safety: broaden IPv6 link-local detection to the full fe80::/10 range
(fe80:: through febf::), not just the fe80:: prefix (+ regression tests).
- playlist.events: cap authorizedWritePaths (evict oldest past 32) so a save
dialog opened without a following write cannot accumulate entries until restart.
- web-player-view: add a @placeholder to each @defer (on immediate) player block
to avoid the one-frame blank/layout-shift before the chunk resolves.
* fix(security): close Electron network and download gaps
* test(downloads): cover cancellation and restart cleanup
* fix(downloads): address Greptile review gaps
* test(security): reproduce remaining Greptile findings
* fix(security): close remaining Greptile findings
* test(downloads): reproduce early database queue stall
* fix(downloads): release queue after setup failures
* test(downloads): reproduce completion queue stall
* fix(downloads): release queue after completion failures
- Moved Stalker-related components and services from apps/web to libs/portal for better modularity.
- Introduced SQLite DB Worker to handle non-EPG database operations, improving UI responsiveness.
- Updated documentation for the Workspace Dashboard and Shell, detailing current implementation and routing structure.
