| DR-261 | Subtitles are drawn **over the picture, not on a black bar across it**. `SubtitleView.setUserDefaultStyle()` reads Android's captioning preferences and falls back to media3's `DEFAULT` when the viewer has set none — and that default is white on opaque black, so every line arrived in a box as wide as the text. The viewer's own style is kept and only the two colours that paint a box, background and window, are cleared: someone who has configured captions in accessibility settings has said something specific about colour, typeface and edges, and replacing all of it to remove a background would answer a question they did not ask. A style specifying no edge gets a black outline, because without a box the text must supply its own contrast or it is unreadable over a bright scene; a style that already names an edge keeps it | Player | UR-020 | Done (pending device verification) |
| DR-262 | The A-Z jump strip is bounded by the **scroller it lives in**, not by the viewport minus a guess at the bottom bars. `AlphabetScrollBar` sized itself as `window.innerHeight` minus a hardcoded `bottomGap` — 5rem, 7rem or 11rem, picked by platform and whether the mini player was showing — which dates from when the mini player and bottom nav were `position: fixed` overlays. They have been in-flow flex siblings below the scroller since BottomUi (DR-009), so the scroller's own bottom edge *is* the top of the mini player and can simply be measured. The guess was short on every device with a navigation or gesture bar, because `--safe-bottom` is padded *inside* BottomUi (DR-112) and no guess knew about it: the strip overran the scrollport by ~45px with the nav alone, ~18px with the mini player and ~50px in remote mode, burying one to three letters where they could not be tapped. The ancestor is resolved by computed `overflow-y` rather than `closest("main")`, since the root shell scrolls in a plain `
` and a miss silently fell back to the viewport — reinstating the bug on any route outside `/library`. Observing the scroller for resize is also what makes the mini player appearing re-measure, so the component no longer subscribes to player or platform stores at all | UI | UR-007 | Done |
| DR-263 | Autoplay crosses the **season boundary**. `fetch_next_episode_for_item` listed the episodes of the current season and stopped dead at the last one, so the end of a season produced `AutoplayDecision::Stop`. On the Android background-audio handoff (UR-040) that is felt as playback simply pausing mid-binge with the screen locked and no UI to un-pause it — the same end that mid-season advances through in the backend. The lookup now walks the series' seasons, sorted client-side by index number because the offline repository ignores `sort_by`, and takes the first episode of the next season that has any, skipping empty ones. Specials are never rolled *into*: Jellyfin numbers them 0 so they sort ahead of season 1, but a server that leaves the index unset sorts them last, exactly where the walk would land. The lookup sits below the sleep-timer gate in `on_playback_ended`, so a timer set to end-of-episode or a remaining-episode count still stops at the boundary rather than being carried past it | Player | UR-023, UR-040 | Done |
+| DR-264 | The episode a viewer *just finished* is no longer offered as the one they are up to. Nothing records completion locally: the stop report writes a position through `storage_update_playback_progress` (which never sets `is_played`), and the cache mirror carried the server's flag not at all — so on a cache hit every episode read back as unwatched. Leaving the player with Back reloads the series page within a second of the stop report, inside the window where Jellyfin's Next Up still names the episode that just ended, and `pick_current_episode` handed it straight back: the season view kept the yellow ring and the "Up next" badge on the episode the viewer had just watched, and scrolled to it. Two halves. (a) `is_finished` — the played flag **or** a position at or past `MAX_PROGRESS_FRACTION` of the runtime, the same 95% threshold that already disqualifies an episode from counting as in-progress — replaces the bare `is_played` in the furthest-watched scan and the first-unwatched fallback, and screens the Next Up candidate: the server is one stop-report behind for a moment, the local position is not. (b) `OfflineRepository::mirror_user_data` carries `is_played` alongside the favourite flag and the position, under the same `pending_sync = 0` conflict rule, so watched state survives a cache write instead of being dropped — that flag was previously written by nothing but an explicit local toggle | Repository | UR-062 | Done |
| DR-198 | The webview runs under a real Content-Security-Policy, and the asset protocol is scoped to the one directory it still serves. `csp` was `null`, which disables CSP entirely: any script that reached the web layer — through a future `{@html}`, a dependency, or a devtools paste — would have inherited the whole IPC surface, and with it the user's session. `script-src 'self'` (Tauri injects a nonce for SvelteKit's inline bootstrap script at build time, so no `'unsafe-inline'` is needed) plus `object-src`/`frame-src 'none'` and `base-uri 'self'` is the part that is genuinely restrictive. `img-src`/`media-src`/`connect-src` cannot be: the Jellyfin origin is typed in by the user at run time and is commonly plain `http` on a LAN, so they allow `http:`/`https:` — a wide grant for *data*, but one that still bars `file:`, `filesystem:` and scripting schemes, and leaves `script-src` untouched. `style-src` keeps `'unsafe-inline'` because Svelte compiles `style="…"` attributes (including `app.html`'s `display: contents` wrapper) into markup; this is safe only while no `
