+ * Pipeline shape (see utils/audio-pcm-cache.ts for the rationale):
+ * an ffmpeg process decodes the episode at full speed into a
+ * position-indexed PCM cache; the render loop reads the window ending at
+ * the player's current position from that cache. Because reads are
+ * indexed by playback time, PAUSE/RESUME/SEEK/SPEED need no pipeline
+ * choreography at all — and cannot desync:
+ *
+ * - Pause: stop the render loop and the decode pass; the PCM cache stays
+ *   resident. Bars freeze on the last rendered frame.
+ * - Resume: re-arm the render loop — bars render instantly from the cache
+ *   — and continue the tail decode in the background. No cold start, no
+ *   coverage guessing, no clamped-buffer freeze (the old bug: resume
+ *   re-armed the loop over a DEAD ffmpeg and the bars exhausted the ring
+ *   buffer, then froze on a repeated stale window forever).
+ * - Seek into decoded audio: nothing to do. Seek into a hole: kick off a
+ *   decode segment there; the last frame holds until data arrives.
+ * - Speed changes: nothing. The cache is position-indexed raw PCM.
+ *
+ * Focus lifecycle: Shell unmounts a tab's page when it loses focus, but the
+ * pipeline outlives the page so playback keeps visualizing; UNLOAD_DELAY_MS
+ * after the Player tab stops being focused it tears down. Reads outside
+ * decoded coverage return empty — the renderer simply holds the last frame
+ * until the decode frontier arrives.
+ *
+ * Loading semantics: `isLoading` is true from any pipeline start (cold
+ * start, resume into undecoded audio) until the first complete FFT frame,
+ * and `isStalled` while playback claims to be live but the position clock
+ * is frozen (player re-buffering). The component renders the spinner for
+ * either; bars replace it the moment fresh frames arrive.

+ * for the app's lifetime instead of spawning a fresh player per episode:
+ *
+ * - Play/pause/seek are IPC commands on a persistent Unix-socket
+ *   connection — no process spawn, no socket connect/disconnect churn per

+ * - State (time-pos, pause, duration) is OBSERVED (`observe_property`):
+ *   mpv pushes time-pos at ~20Hz while playing, so `getPosition()` /
+ *   `getPauseState()` read a cache instead of round-tripping the socket on
+ *   every 150ms UI tick. External pauses (AirPod removal, system sleep,
+ *   Now Playing center) arrive as pause property events with zero polling.
+ * - A restored session can PRELOAD: the episode is loaded paused so mpv
+ *   fills its demuxer cache ahead of time; the first real play just flips
+ *   `pause` to false — the ~2s network open is paid at boot, not on the
+ *   user's first Play.
+ * - Crash/kill recovery: a dead daemon (process exit or broken IPC socket)
+ *   is detected on the next command; play() respawns a fresh daemon and
+ *   reloads. resume() cannot unpause a freshly-idle daemon — it throws

+  depends_on: []
+  tags: [implementation, tests-required]
+
+objective:
+
+- Bound what the app writes to `config.json`: each persisted feed keeps only episodes published within the last 30 days, plus any episode whose download is completed — everything older lives in volatile memory only (wired up in task 02). Loading an over-window legacy config must prune it automatically (cleanup on first launch).
+
+background (read this before touching code):
+
+- Feeds persist through `src/utils/feeds-persistence.ts`. `saveFeedsToFile(feeds)` is a fire-and-forget wrapper around `updateConfig({ feeds })` in `src/utils/config.ts`, which read-modify-writes the whole `config.json` behind a serialized promise chain (`writeChain`).
+- Today `saveFeedsToFile` writes every loaded episode, so `config.json` grows forever (the Feed page's "Fetch More" keeps expanding `feed.episodes` and saving).
+- Downloads persist separately in `downloads.json` (same config dir, see `src/utils/config-dir.ts` `getConfigFilePath("downloads.json")`). Each record has `episodeId`, `status`, `feedId`, etc. The `DownloadStatus` enum lives in `src/types/episode.ts` — read it there for the completed member's string value; do NOT hardcode a guessed string.
+- `src/stores/feed.ts` calls `saveFeedsToFile` from a module-scope `saveFeeds()` helper. Callers must not change in this task.
+- Style: match the file you edit. `feeds-persistence.ts` and `config.ts` are tab-indented WITH semicolons (some other repo files aren't — don't "fix" that anywhere).
+
+deliverables:
+
+- `src/utils/feeds-persistence.ts`:
+  - New exported constant `EPISODE_WINDOW_DAYS = 30` — the lifecycle window: bounds BOTH persistence (here) and the volatile episode list/cache (task 02).
+  - New exported pure function `episodeInWindow(ep: Episode, now: Date): boolean` — returns `true` when `ep.pubDate` is missing/not a valid `Date` (fail-safe: never drop an undatable episode) OR `ep.pubDate.getTime() >= now.getTime() - EPISODE_WINDOW_DAYS * 24 * 3600 * 1000`.
+  - New exported pure function `episodeIsPersistable(ep: Episode, downloadedIds: Set<string>, now: Date): boolean` — returns `true` when `downloadedIds.has(ep.id)` OR `episodeInWindow(ep, now)`.
+  - New (module-private) async helper `readDownloadedEpisodeIds(): Promise<Set<string>>` — reads `getConfigFilePath("downloads.json")` with `Bun.file`, returns the `episodeId`s of records whose `status` equals `DownloadStatus.COMPLETED`; returns an empty set on any error or missing file. Note: an episode whose download is merely in-flight is NOT exempted; it will be re-included by the next save after completion, since the in-memory `feed.episodes` still holds it — document this in the function comment.
+  - `saveFeedsToFile(feeds: Feed[])` — before calling `updateConfig`, map each feed to `{ ...feed, episodes: feed.episodes.filter(ep => episodeIsPersistable(ep, downloadedIds, new Date())) }`. The downloaded-ids lookup is async, so wrap the whole body in a fire-and-forget async IIFE (`.catch(() => {})`) that preserves the existing sync/fire-and-forget signature; on any lookup failure, save the feeds unpruned (never lose data on an error path).
+  - `loadFeedsFromFile()` — after `reviveDates`, apply the same prune to the loaded feeds; if the prune removed at least one episode, call `saveFeedsToFile(pruned)` to rewrite `config.json` (this is the startup cleanup for legacy configs). `await` the prune path deterministically (the function is already async).
+- `src/utils/config.ts`:
+  - New exported `whenConfigIdle(): Promise<void>` returning the module-internal `writeChain` promise. Tests need a way to await pending serialized writes; today `updateConfig` hides the chain and tests cannot observe when a write lands.
+- `tests/feed-retention.test.ts` (new) — see tests section.
+
+steps:
+
+1. Read `src/types/episode.ts` to confirm `DownloadStatus.COMPLETED`'s runtime value and the `Episode` shape (`id`, `pubDate`).
+2. Read `src/utils/feeds-persistence.ts` and `src/utils/config.ts` fully (they are short).
+3. Add `whenConfigIdle()` to `config.ts` next to `updateConfig`.
+4. In `feeds-persistence.ts`: add imports (`getConfigFilePath` from `./config-dir`, `DownloadStatus` and `type Episode` from `../types/episode`), the constant, `episodeIsPersistable`, `readDownloadedEpisodeIds`, then rework `saveFeedsToFile` and `loadFeedsFromFile` per deliverables. Keep `reviveDates` untouched.
+5. Ensure `saveFeeds` in `src/stores/feed.ts` still compiles unchanged (signature-compatible).
+6. Write `tests/feed-retention.test.ts`, run it, then run the full suite and lint.
+
+tests:
+
+- Conventions (copy them): `tests/feed-refresh.test.ts` shows the harness — `mkdtempSync` into `process.env.XDG_CONFIG_HOME` **before** importing anything under test (module-level init reads the config dir), `rmSync` in `afterAll`, tabs/no-semicolon style not required but match repo.
+- New `tests/feed-retention.test.ts`:
+  - Unit (Arrange–Act–Assert) for `episodeIsPersistable`:
+    - episode 40 days old, not downloaded → `false`.
+    - episode 40 days old, id in `downloadedIds` → `true`.
+    - episode 5 days old → `true`.
+    - episode with `pubDate: new Date(NaN)` → `true` (fail-safe).
+  - Save-path integration:
+    - Arrange: write a `downloads.json` in the temp config dir containing one `completed` record for `old-downloaded-id` (include all fields the loader reads in `src/stores/download.ts`'s `DownloadRecord`: at minimum `episodeId`, `feedId`, `status`, `filePath: null`, `downloadedAt: null`, `fileSize: 0`, `error: null`, `audioUrl: ""`, `episodeTitle: ""`).
+    - Act: call `saveFeedsToFile([feed])` where the feed has three episodes — recent, old-not-downloaded (`id: "old-plain-id"`), old-downloaded (`id: "old-downloaded-id"`). Await `whenConfigIdle()` (plus one more microtask/`await Promise.resolve()` round if the async IIFE resolves after the chain call — flush both).
+    - Assert: parse `config.json` raw; the feed's persisted `episodes` contain the recent and `old-downloaded-id` episodes and NOT `old-plain-id`.
+  - Load-path cleanup:
+    - Arrange: seed `config.json` (write it directly with `Bun.write`) with one feed holding only over-window episodes; no `downloads.json`.
+    - Act: `await loadFeedsFromFile()`, then `await whenConfigIdle()`.
+    - Assert: returned feed has zero episodes AND re-reading `config.json` shows the episodes pruned (cleanup rewrite happened).
+
+acceptance_criteria:
+
+- `saveFeedsToFile` never writes an episode older than 30 days unless its id is a completed download in `downloads.json`.
+- `loadFeedsFromFile` prunes over-window episodes from legacy configs and rewrites `config.json` when it pruned anything.
+- Undatable episodes (`pubDate` missing/invalid) are always persisted.
+- No call site of `saveFeedsToFile`/`loadFeedsFromFile` needed to change (compatible signatures).
+- `bun test tests/feed-retention.test.ts` passes; the existing `bun test` suite passes; `bun run lint` is clean.
+
+validation:
+
+- `bun test tests/feed-retention.test.ts`
+- `bun test` (full suite — watch `feed-refresh`/`feed-pagination` for regressions)
+- `bun run lint`
+- Manual smoke (optional): `bun start`, subscribe to any feed, quit, then `cat ~/.config/podtui/config.json | python3 -c "import sys,json; print(max(e['pubDate'] for f in json.load(sys.stdin)['feeds'] for e in f['episodes']))"` and confirm no persisted episode is older than 30 days.
+
+notes:
+
+- `updateConfig` captures the patched data eagerly at call time (`JSON.parse(JSON.stringify(patch))`), so pruning in `saveFeedsToFile` before the `updateConfig` call is exactly where the filter must live — filtering later would be silently ineffective for already-queued writes.
+- This task intentionally does NOT change in-memory behavior, refresh merging, or cache bounds — that is task 02. If both are worked on in parallel, 02 imports nothing from 01 except the documented window semantics; the module-level contract above is the seam.
+- `downloads.json` is written by `src/stores/download.ts` (`saveDownloads`); reading it directly here avoids a store→module import cycle (download.ts already imports the feed store).

+# 02. Merge refreshes against the volatile in-memory episode window with a date-windowed cache
+
+meta:
+  id: bounded-feed-lifecycle-02
+  feature: bounded-feed-lifecycle
+  priority: P2
+  depends_on: [bounded-feed-lifecycle-01]
+  tags: [implementation, tests-required]
+
+objective:
+
+- Refreshing a feed must UNION the freshly fetched latest window with the episodes already in memory (instead of replacing), so episodes that task 01 pruned from disk — or deep episodes pulled in via "Fetch More" — survive refreshes within a session. Bound in-memory retention by the SAME date window persistence uses (`EPISODE_WINDOW_DAYS`, 30 days) instead of an episode count: the visible list and the pagination cache hold every episode from the last 30 days, and episodes older than that age out of the list on the next refresh (`fullEpisodeCache` currently holds every parsed episode of every feed ever fetched).
+
+background (read this before touching code):
+
+- All work lands in `src/stores/feed.ts` plus one new pure-utils module. Current behavior to change:
+  - `fetchEpisodes(feedUrl, limit, feedId?)` parses the whole feed, stores ALL episodes in the module-level `fullEpisodeCache` Map, returns the first `limit`.
+  - `refreshFeed` / `refreshAllFeeds` pass the fetched window through `applyRefreshedEpisodes`, which REPLACES `feed.episodes` when ids differ (`sameEpisodes` id-set compare; unchanged → keep object identity and skip save — this order-stability contract is pinned by `tests/feed-refresh.test.ts` and must keep passing).
+  - `loadMoreEpisodesForFeed` grows the displayed window from `fullEpisodeCache` (fetching+parsing the full feed when the cache is cold — e.g. after a restart), tracking progress in `episodeLoadCount`.
+- Task 01 made persistence prune everything over 30 days old (except completed downloads). After a restart, `feed.episodes` therefore only contains the 30-day persisted window; the full cached episode list is rebuilt lazily by the first fetch-more or refresh within the new session. This task makes the session-time behavior correct: fetched refreshes merge (never replace), and the volatile list + cache are bounded by the SAME 30-day window persistence uses — what can be browsed is exactly what can be persisted, and episodes older than the window age out on refresh.
+- Style: `feed.ts` is tab-indented WITH semicolons. New utils file: match `src/api/rss-parser.ts` style (2-space, no semicolons).
+
+deliverables:
+
+- `src/utils/feeds-persistence.ts` (the canonical window owner):
+  - Rename the retention constant to `EPISODE_WINDOW_DAYS = 30` — it now bounds the volatile cache/list as well as persistence.
+  - New exported `episodeInWindow(ep: Episode, now: Date): boolean` — `pubDate >= now - EPISODE_WINDOW_DAYS`; missing/invalid pubDates are ALWAYS kept (fail-safe mirror of the persistence rule, so cache and disk can never disagree about an undatable episode). `episodeIsPersistable` becomes `downloadedIds.has(ep.id) || episodeInWindow(ep, now)`.
+- Rework `src/utils/episode-merge.ts` (pure, store-free, unit-testable):
+  - `mergeEpisodesInWindow(existing: Episode[], fetched: Episode[], now: Date): Episode[]` — union by `ep.id`; on id collision the `fetched` copy wins (fresh metadata); result sorted by `pubDate` descending; pruned to the lifecycle window via `episodeInWindow` (out-of-window episodes dropped, undated kept). No count cap — the bound is the date.
+  - Invariants: never mutates inputs; stable output for `existing=[]`; entries with invalid `pubDate` sort as newest (use `getTime()`, treat `NaN` as `+Infinity` with a small `ts()` helper).
+- `src/stores/feed.ts`:
+  - Delete `MAX_EPISODES_IN_MEMORY` — no episode-count bound anywhere.
+  - `fetchEpisodes`: window-filter the parsed feed (`allEpisodes.filter(ep => episodeInWindow(ep, new Date()))`) BEFORE caching and returning: `fullEpisodeCache.set(feedId, windowed)` and `episodes: windowed.slice(0, limit)`. The limit is a page size; the window is the bound.
+  - `applyRefreshedEpisodes(prev, feedId, episodes)`: replace the `sameEpisodes` replace-with-fetched logic with merge semantics:
+    - Compute `merged = mergeEpisodesInWindow(f.episodes, episodes, new Date())`.
+    - Unchanged detection must compare the FETCHED window against the corresponding prefix of the existing list, i.e. keep a small `sameRefreshWindow(existing: Episode[], fetched: Episode[])` helper next to (and replacing the use of) `sameEpisodes`: `fetched.length === 0 → true`; otherwise compare id-sets of `fetched` and `existing.slice(0, fetched.length)`. Rationale: with union semantics `merged` legitimately contains episodes beyond the fetched window, so comparing full lists would bump `lastUpdated` on every refresh and resurrect the order-flapping bug `tests/feed-refresh.test.ts` guards.
+    - Return unmodified `prev` when every feed's window is unchanged (preserve the existing identity-no-save contract); on change, set `{ ...f, episodes: merged, lastUpdated: new Date() }`.
+    - Delete the now-unused `sameEpisodes` if nothing else references it (grep first: `grep sameEpisodes src tests`).
+  - `loadMoreEpisodesForFeed`: window-filter the cold-refetch cache the same way after `parseEpisodesIncremental` (it's unsorted there — wrap with `sortEpisodesReverseChronological` before filtering). Fetch-more stepping is mode-dependent: DATE mode advances the loaded window by a `FETCH_MORE_WINDOW_DAYS` (14) band past the oldest loaded episode — a daily show gains ~2 weeks of episodes per press, not a fixed count — with a +1 minimum so a sparse band can't wedge the button into a no-op; COUNT mode keeps the fixed `MAX_EPISODES_REFRESH` (50) chunk. `hasMoreEpisodes` still compares `episodeLoadCount < cached.length`.
+- `tests/feed-volatile-merge.test.ts` (reworked) — see tests section.
+
+steps:
+
+1. Read `src/stores/feed.ts` fully and `tests/feed-refresh.test.ts` + `tests/feed-pagination.test.ts` (they pin the contracts you must not break; reuse their harness).
+2. Rework `src/utils/episode-merge.ts` to `mergeEpisodesInWindow`; add `episodeInWindow` (and rename `PERSISTED_WINDOW_DAYS` → `EPISODE_WINDOW_DAYS`) in `feeds-persistence.ts`.
+3. Integrate in `feed.ts`: replace `sameEpisodes` usage with `sameRefreshWindow` + `mergeEpisodesInWindow` in `applyRefreshedEpisodes`; window-filter `fullEpisodeCache` writes and the returned window in `fetchEpisodes` and `loadMoreEpisodesForFeed`; delete `MAX_EPISODES_IN_MEMORY`.
+4. Run the existing feed tests — all must pass unchanged (merge must keep order stability and pagination intact).
+5. Write the new tests, run, then full suite + lint.
+
+tests:
+
+- New `tests/feed-volatile-merge.test.ts`:
+  - Pure unit (Arrange–Act–Assert) for `mergeEpisodesInWindow(existing, fetched, now)`:
+    - dedupe on collision, fetched copy wins (mutate title in the fetched twin, assert the merged entry shows the new title).
+    - union of disjoint lists sorted by `pubDate` desc.
+    - window prune drops out-of-window episodes from BOTH inputs and keeps undated (NaN pubDate) episodes.
+    - input arrays not mutated.
+  - Store integration (harness per `tests/feed-refresh.test.ts`: temp `XDG_CONFIG_HOME` BEFORE imports, `Bun.serve` on port 0 serving generated RSS, fake timers):
+    - Refresh-keeps-volatile-window: serve 3 episodes at t0, `addFeed`; then serve the same 3 plus 2 new ones, `refreshFeed`. Assert `feed.episodes.length === 5` AND `lastUpdated` advanced AND a second identical refresh leaves `lastUpdated` untouched (window-compare, not union-compare).
+    - Boundary: a 25-day-old episode loads; a 70-day-old episode is neither visible nor cached initially, but fetch-more surfaces it (volatile).
+    - Date stepping: 30 episodes at 3-day spacing — each fetch-more press reveals the next 2-week band (24 → 28 → 30), NOT a fixed 50-chunk.
+    - Count-mode global step: two feeds with staggered dates — one Feed-page press adds the configured N most-recent UNLOADED episodes across ALL shows (N total, not N per show), via the k-way frontier merge in `loadMoreAllFeedsByCount`.
+    - Out-of-window never cached: 600 items at 2h spacing span ~50 days — only the in-window tail is loadable (fewer than the old 500 cap), `hasMoreEpisodes` flips false there.
+    - No count ceiling: 600 items at 1h spacing (all within 25 days) are ALL loadable — the bound is the date, not a number.
+  - Clock constraint: these tests run under fake timers, and a large `vi.advanceTimersByTime` (past ~5 days of fake time) makes Bun 1.3.8 hang every subsequent network fetch — the boundary is pinned with relative pubDates, never by moving the clock across it.
+- Existing suites that must keep passing: `tests/feed-refresh.test.ts`, `tests/feed-pagination.test.ts`, `tests/feed-refresh-spinner.test.tsx`.
+
+acceptance_criteria:
+
+- A refresh never removes an episode that was visible before the refresh during the same session — except episodes that aged past the window, which drop out on refresh (the date bound).
+- An unchanged refresh does not bump `lastUpdated` (object identity of the feed is preserved).
+- Per-feed cached/parsed episodes are exactly the in-window set: nothing outside the last `EPISODE_WINDOW_DAYS` days is cached or loadable, and everything inside is (no count ceiling).
+- After a simulated restart (fresh store boot from a pruned config), fetch-more re-parses the feed and applies the same window to the cache.
+- `bun test` full suite passes; `bun run lint` clean.
+
+validation:
+
+- `bun test tests/feed-volatile-merge.test.ts tests/feed-refresh.test.ts tests/feed-pagination.test.ts`
+- `bun test`
+- `bun run lint`
+- Manual smoke: `bun start`, drill a show in My Shows, fetch-more a few pages, press `r` to refresh — the in-window pages stay; quit and relaunch — the list holds only the 30-day window, and fetch-more re-parses the feed with the same window applied.
+
+notes:
+
+- Depends on task 01 only conceptually: without the persisted-window prune, this merge is still correct but harder to observe. If 01 isn't merged yet, the store tests still pass; the "restart keeps only 30 days" manual check requires 01.
+- `fullEpisodeCache`/`episodeLoadCount` are module-level Maps in `feed.ts` — the window filter belongs at the two write sites named in deliverables, not in a wrapper.
+- Do not touch persistence writes in this task; debounced save behavior is task 03. Keep calling the module-scope `saveFeeds(updated)` helper exactly as today.

+  - `parseEpisodesIncremental` already chunks XML parsing and yields to the event loop via MessageChannel — keep that mechanism untouched; the blocking/stall risk today is the fetch barrier and the save path.
+  - `loadMoreEpisodesForFeed`'s cold-cache refetch has NO timeout (copy the `AbortSignal.timeout(FETCH_TIMEOUT_MS)` pattern from `fetchEpisodes`).
+  - Persistence: `saveFeeds(updated)` → `saveFeedsToFile` → `updateConfig`, a serialized full-file read-`JSON.parse`-stringify-`Bun.write` chain in `src/utils/config.ts`. Called from `refreshFeed`, `refreshAllFeeds`, `loadMoreEpisodesForFeed`, `addFeed`, `removeFeed*`, `updateFeed`, `togglePinned`.
+  - The boot IIFE calls `refreshAllFeeds()` right after `loadFeedsFromFile()` — this is the cold-start refresh users currently feel; first paint already happens because module init is async, but nothing renders per-feed until the barrier resolves.
+  - Single feed `refreshFeed` applies its own `setFeeds` immediately — reuse exactly that shape (fetch → apply-if-changed → mark save dirty) for the incremental batch path.
+- Tasks 01+02 must be merged first: this task debounces the pruned save path (01) and applies per-feed results through `applyRefreshedEpisodes`/`mergeEpisodes` (02).
+- Style: tab-indented WITH semicolons, JSDoc comments on non-obvious functions, section dividers `// ── Name ──…` per repo convention.
+- Tests here use `vi.useFakeTimers()` — `setTimeout`-based debounce must therefore be advanced with `vi.advanceTimersByTime` in tests; don't use `queueMicrotask`-style scheduling for the debounce.
+
+deliverables:
+
+- `src/stores/feed.ts`:
+  - New constant `FETCH_CONCURRENCY = 4` (comment: bounds simultaneous RSS requests; a hung feed burns at most one slot for `FETCH_TIMEOUT_MS`).
+  - New module-level async helper `mapWithConcurrency<T, R>(items: T[], limit: number, fn: (item: T) => Promise<R>): Promise<R[]>` — classic worker-pool: `limit` workers pulling indexes from a shared counter, results in input order. Pure and generic enough to unit-test.
+  - Rewritten `refreshAllFeeds()`:
+    - `setIsLoadingFeeds(true)` … `finally setIsLoadingFeeds(false)` as today.
+    - Process feeds through `mapWithConcurrency(feeds(), FETCH_CONCURRENCY, async (feed) => ...)`.
+    - Inside the per-feed callback: `fetchEpisodes(feed.podcast.feedUrl, MAX_EPISODES_REFRESH, feed.id)`; if non-null, immediately `setFeeds(prev => { const updated = applyRefreshedEpisodes(prev, feed.id, episodes); if (updated !== prev) scheduleSaveFeeds(); return updated; })`. Failed feeds (null) stay untouched, as today.
+    - After all workers settle: ONE `runAutoDownload()` (as today), and `flushPendingSave()` (below) so a refresh batch always ends with a persisted write when anything changed.
+  - Debounced save plumbing (module scope, replacing direct calls):
+    - `let pendingSaveTimer: ReturnType<typeof setTimeout> | null = null; const SAVE_DEBOUNCE_MS = 250;`
+    - `scheduleSaveFeeds()` — after a state-changing update, mark dirty: set a `savePending = true` flag and (re)arm the trailing timer to fire `flushPendingSave()`.
+    - `flushPendingSave()` — if `savePending`, snapshot `feeds()`, call `saveFeeds(snapshot)`, clear flag/timer. Export it on the store's returned object (tests need it; also lets task 04/a future quit hook force a write).
+    - Convert ALL direct `saveFeeds(updated)` / `saveFeeds(newList)` call sites inside `setFeeds` callbacks to `scheduleSaveFeeds()` EXCEPT `removeFeed`/`removeFeedByUrl`, which must call both `scheduleSaveFeeds()` AND `flushPendingSave()` (an unsubscribe intent should not sit unsaved through the debounce window if the process exits). Keep the change mechanical: same call sites, new indirection.
+  - `loadMoreEpisodesForFeed`: add `signal: AbortSignal.timeout(FETCH_TIMEOUT_MS)` to the cold refetch and return early on non-OK/throw (wrap in try/catch mirroring `fetchEpisodes`).
+- `tests/feed-nonblocking.test.ts` (new) — see tests section.
+
+steps:
+
+1. Read `src/stores/feed.ts` and confirm tasks 01/02 are merged (`episodeIsPersistable` in `src/utils/feeds-persistence.ts`, `mergeEpisodes` in `src/utils/episode-merge.ts`).
+2. Add `FETCH_CONCURRENCY`, `mapWithConcurrency`, and the debounce plumbing.
+3. Rewrite `refreshAllFeeds` per deliverables; convert the save call sites.
+4. Add the fetch timeout to `loadMoreEpisodesForFeed`'s cold refetch.
+5. Export `flushPendingSave` from the store's return object (Actions section).
+6. Write `tests/feed-nonblocking.test.ts`; run new + existing feed tests; full suite; lint.
+
+tests:
+
+- Harness conventions: copy `tests/feed-refresh.test.ts` (temp `XDG_CONFIG_HOME` BEFORE store imports; `Bun.serve` port 0; `vi.useFakeTimers()` in `beforeEach`). Note `vi.advanceTimersByTime(...)` also drives the debounce timer and the MessageChannel yields used by the parser are real task-queue turns (safe under fake timers per the comment on `yieldToUI`).
+- New `tests/feed-nonblocking.test.ts`:
+  - Concurrency bound: server records concurrent in-flight requests (increment on entry, `await new Promise(r => setTimeout(r, 50_000))` under fake-timer awareness: use a gate promise the test controls instead of real sleeps — release gates with `vi.advanceTimersByTime` after asserting). Register 10 feeds; start `refreshAllFeeds()` (don't await); assert the server's max-concurrent counter never exceeded 4; release all gates and await completion.
+  - Incremental apply: 2 feeds — one served instantly, one gated. Start refresh; resolve the fast gate only; assert the fast feed's `lastUpdated`/episodes already updated in `feeds()` BEFORE the slow feed resolves (this is the acceptance proof the `Promise.all` barrier is gone). Then release the slow gate and assert both applied.
+  - Debounce: mock-observe writes by seeding the temp config dir and spawning two rapid refreshes whose content changed; `await` both, then `vi.advanceTimersByTime(SAVE_DEBOUNCE_MS)`; read raw `config.json` ONCE — assert both new episodes are present in a single coherent write. (Counting writes precisely is brittle against `updateConfig`'s chain; asserting final content + that the pre-debounce file lacks the episodes is the binary check: before advancing the debounce, `config.json` must NOT yet contain the new episodes; after, it must.)
+  - `flushPendingSave`: refresh with changed content, call `store.flushPendingSave()` without advancing timers, assert `config.json` already contains the new episode.
+- Existing suites must pass unchanged: `feed-refresh.test.ts`, `feed-pagination.test.ts`, `feed-volatile-merge.test.ts`, `feed-refresh-spinner.test.tsx`, `restore-session.test.ts`.
+
+acceptance_criteria:
+
+- During a refresh batch, no more than `FETCH_CONCURRENCY` HTTP requests are ever in flight.
+- Each feed's refreshed episodes are visible in `feeds()` as soon as its own fetch resolves — no waiting for the slowest feed.
+- Writes to `config.json` are trailing-edge debounced: rapid successive updates produce one final write after the settle window, and `flushPendingSave()` persists immediately.
+- `loadMoreEpisodesForFeed`'s refetch aborts at `FETCH_TIMEOUT_MS` instead of hanging forever.
+- `bun test` full suite passes; `bun run lint` clean.
+
+validation:
+
+- `bun test tests/feed-nonblocking.test.ts tests/feed-refresh.test.ts tests/feed-pagination.test.ts tests/feed-volatile-merge.test.ts`
+- `bun test`
+- `bun run lint`
+- Manual smoke: `bun start` with several subscriptions; hold `j` during the startup refresh — selection moves smoothly and per-feed results appear as they land; quit/relaunch and confirm the last refresh's episodes persisted.
+
+notes:
+
+- The background refresh timer (`scheduleNextRefresh`) already skips ticks while `isLoadingFeeds()` is true — unchanged.
+- Do not introduce a real "sleep" anywhere in tests; gates + fake timers only, matching existing suites.
+- `mapWithConcurrency` is generic; keep it module-private in `feed.ts` (no premature new util file).
+- `updateConfig` snapshots its patch at call time (`JSON.parse(JSON.stringify(patch))`), so debouncing by delaying the `saveFeeds` CALL is correct — a pending write always serializes the latest feeds it was handed.

+# 04. Add a shared activity store and global top-right loading indicator
+
+meta:
+  id: bounded-feed-lifecycle-04
+  feature: bounded-feed-lifecycle
+  priority: P2
+  depends_on: [bounded-feed-lifecycle-03]
+  tags: [implementation, tests-required]
+
+objective:
+
+- One global indicator, always in the top-right corner of the app, visible whenever ANYTHING is being loaded or downloaded: feed refreshes (all-feeds and single-feed), fetch-more, subscribe fetches, searches, and episode downloads. Per-page spinners stay as-is; this adds the global signal that activity is happening anywhere.
+
+background (read this before touching code):
+
+- `src/components/Shell.tsx` renders the whole chrome: one full-width content row (`LayerGraph[nav.activeTab()]()` / `PaneRow`) plus a bottom status/command bar. There is no header row — the top-right corner belongs to whatever page is active, so the indicator must be an ABSOLUTE-POSITIONED overlay drawn after the content so it paints on top (opentui `box` supports `position="absolute"`, `top`, `right`).
+- Existing activity signals (read them, don't recreate per-store bookkeeping): `useFeedStore().isLoadingFeeds()` / `.isLoadingMore()`; `useSearchStore().isSearching()` (`src/stores/search.ts`); `useDownloadStore().getActiveCount()` and `.getQueue().length` (`src/stores/download.ts`). Gaps these don't cover: single `refreshFeed`, `addFeed`'s subscribe fetch, iTunes feed resolution inside `addFeed` — hence the activity store.
+- `src/components/LoadingIndicator.tsx` is the braille spinner (prop `label?: string`); reuse it inside the overlay.
+- Activity tracking must be leak-proof: every `begin` paired with an `end` via a token, PLUS a `track(promise, label)` helper that auto-ends on settle so callers can't strand the counter.
+- Task 03 added the incremental per-feed apply inside `refreshAllFeeds`; wire activity around the whole batch ( `isLoadingFeeds` already brackets it — prefer reusing the signal, adding explicit `begin/end` ONLY where no signal exists).
+- Style: Solid + `@opentui/solid` JSX (no `className`; props like `fg`, `paddingRight`, `position`); store files tab-indented with semicolons; components match `LoadingIndicator.tsx` conventions. Style imports use `@/` alias in components, relative paths in stores.
+
+deliverables:
+
+- New `src/stores/activity.ts`:
+  - Signals: `count` (number), `labels` (string[]).
+  - Actions: `beginActivity(label: string): () => void` (returns the matching end function; each call adds the label, ending removes that exact instance — duplicates allowed), `track<T>(p: Promise<T>, label: string): Promise<T>` (begins, ends in `finally`, re-throws).
+  - Computed: `isActive(): boolean` (`count() > 0`).
+  - Singleton + `useActivityStore()` accessor, mirroring `src/stores/download.ts`'s module pattern.
+- Wire the gaps in `src/stores/feed.ts` (only where no existing signal covers the operation):
+  - `refreshFeed`: `await activity.track(...)` around the fetch+apply, label `"Refreshing"`.
+  - `addFeed`: wrap the directory-resolve + `fetchEpisodes` stretch, label `"Subscribing"`.
+  - Do NOT wrap `refreshAllFeeds`/`loadMoreEpisodes*` — `isLoadingFeeds`/`isLoadingMore` already cover them (double-counting just lengthens the spinner's on-time cosmetically; the point is no visual gap).
+- New `src/components/GlobalActivityIndicator.tsx`:
+  - Computes active state from: `feedStore.isLoadingFeeds() || feedStore.isLoadingMore() || searchStore.isSearching() || downloadStore.getActiveCount() + downloadStore.getQueue().length > 0 || activity.isActive()`.
+  - Label selection: downloads in flight → `Downloading N` (+`M queued` when queue non-empty); else the activity store's latest label + `…` (e.g. `Refreshing…`); else `Loading…`.
+  - Renders `<LoadingIndicator label={…} />` inside `<box position="absolute" top={0} right={0} paddingRight={1}>`; renders nothing (returns `null`) when inactive so it never eats layout when idle.
+- `src/components/Shell.tsx`: mount `<GlobalActivityIndicator />` as the LAST child of the root `<box flexDirection="column" …>` (after the content row, bottom bar, and help overlay so it paints on top).
+- `tests/global-activity-indicator.test.tsx` (new) — see tests section.
+
+steps:
+
+1. Read `src/stores/download.ts`, `src/stores/search.ts`, `src/components/LoadingIndicator.tsx`, and the render JSX of `src/components/Shell.tsx`.
+2. Write `src/stores/activity.ts` (small; ~60 lines).
+3. Wire `refreshFeed`/`addFeed` in `src/stores/feed.ts` via `useActivityStore().track(...)`. Import cycle note: `activity.ts` must import NOTHING from other stores (pure counter) so `feed.ts` importing it is safe.
+4. Write `src/components/GlobalActivityIndicator.tsx`; mount it in `Shell.tsx` last (paints on top).
+5. Write tests; run new tests, full suite, lint; manual smoke per validation.
+
+tests:
+
+- New `tests/global-activity-indicator.test.tsx` (component-test conventions: copy the render harness from `tests/feed-refresh-spinner.test.tsx` — temp `XDG_CONFIG_HOME` before imports; if a jsdom-like setup is used there, reuse it as-is):
+  - Activity store unit asserts: two `begin`s → `isActive()` true; ending one → still true; ending both → false. `track(failingPromise)` still decrements (rejects propagate, counter returns to baseline).
+  - Component asserts: render `<GlobalActivityIndicator />` in isolation —
+    - idle → no text rendered;
+    - `useActivityStore().beginActivity("Refreshing")` → spinner/label present in rendered output; matching end → gone;
+    - with the download store: enqueue via `downloadStore.startDownload`-equivalent the way `tests/download-unsubscribed.test.ts` does (assert indicator renders while `getActiveCount() + queue > 0`); skip actual network by following that test's existing mocking pattern.
+- Existing suites must pass: `feed-refresh-spinner.test.tsx` (per-page spinners unchanged), full `bun test`.
+
+acceptance_criteria:
+
+- Indicator visible in the top-right overlay while any of: all-feeds refresh, single-feed refresh, fetch-more, subscribe fetch, search, active/queued download — and hidden when none are active.
+- Counter never strands: every completed/failed tracked operation returns `isActive()` to its prior value (proven by the `track` rejection test).
+- Idle UI unchanged: when inactive the overlay renders nothing and occupies zero layout.
+- `bun test` full suite passes; `bun run lint` clean.
+
+validation:
+
+- `bun test tests/global-activity-indicator.test.tsx tests/feed-refresh-spinner.test.tsx`
+- `bun test`
+- `bun run lint`
+- Manual smoke: `bun start`; (a) on cold boot with subscriptions, the top-right spinner appears during startup refresh and disappears when done; (b) press `r` on Feed — spinner appears; (c) download an episode from Search — `Downloading` label shows while the transfer runs; (d) leave idle — top-right is empty.
+
+notes:
+
+- Depends on 03 only for ordering cleanliness — the activity wiring hooks onto the restructured refresh paths; nothing in 03's API is required beyond the store exporting the same signals.
+- The overlay intentionally does NOT replace per-pane spinners (`Refreshing…` in Feed/MyShows/Discover/Search stay) — removing those is out of scope.
+- If `position="absolute"` proves unavailable for text-draw ordering in `@opentui/solid`, the fallback is a dedicated 1-row header (`height={1}`) above the content row with the indicator right-aligned — only take this path with evidence (broken render), and note the tradeoff (loses one row of content height) in the commit message.

+# Bounded Feed Lifecycle
+
+Objective: Bound feed episode storage to a rolling 30-day persisted window (older episodes volatile-only unless downloaded), keep feed loading nonblocking, and surface all load/download activity in a global top-right indicator.
+
+Status legend: [ ] todo, [~] in-progress, [x] done
+
+Tasks
+
+- [x] 01 — persisted-retention-window → `01-persisted-retention-window.md`
+- [x] 02 — volatile-episode-merge → `02-volatile-episode-merge.md`
+- [x] 03 — nonblocking-feed-refresh → `03-nonblocking-feed-refresh.md`
+- [x] 04 — global-activity-indicator → `04-global-activity-indicator.md`
+
+Dependencies
+
+- 02 depends on 01 (the volatile merge preserves exactly what 01 drops from disk)
+- 03 depends on 01 (debounced persistence layers onto the pruning save path)
+- 03 depends on 02 (incremental per-feed apply consumes the merge helper from 02)
+- 04 depends on 03 (the indicator subscribes to the activity wiring added across refresh/load-more paths in 03)
+
+Exit criteria
+
+- After any refresh + save, `config.json` `feeds[*].episodes` contains only episodes with `pubDate` within the last 30 days or episodes marked `completed` in `downloads.json`; loading a legacy config prunes stale episodes on first launch.
+- The volatile episode list and pagination cache are bounded by the same 30-day window as persistence: only in-window episodes are cached/loadable, and everything in-window is (no episode-count ceiling).
+- A refresh batch never exceeds a fixed fetch concurrency, applies each feed's result as it lands (no `Promise.all` barrier), and persistence writes are debounced; keyboard input stays responsive throughout.
+- The top-right indicator is visible iff at least one feed refresh, fetch-more, subscribe fetch, search, or episode download is in flight, hidden otherwise.
+- `bun test` and `bun run lint` pass.

+ * fragile paced-ring design kept breaking:
+ *
+ * 1. readWindow(out, at) serves the EXACT window ending at playback time
+ *    `at` — position mapping is sample-precise, independent of how fast or
+ *    far the decode has run.
+ * 2. Reads outside decoded coverage return 0 — the renderer HOLDS the last
+ *    frame. (The old reader CLAMPED to a stale buffer; re-rendering the
+ *    same window decayed cava into a frozen junk pattern after pause.)
+ * 3. pauseDecode kills ffmpeg but keeps the cache: resume serves bars
+ *    instantly, ensureDecodeAround restarts the tail decode.
+ * 4. Seeking into an undecoded region starts a new segment there WITHOUT
+ *    invalidating the previously decoded coverage.
+ *
+ * Uses a self-generated WAV (440Hz sine, mono, 22050Hz s16le — the cache's

+ * external-pause-reconcile.test.ts — "audio paused outside PodTUI must not
+ * freeze the player tab" regression test.
+ *
+ * The OS can pause the player without PodTUI knowing: system sleep/lock,
+ * AirPod removal / device swap, OS media keys, the Now Playing center. mpv
+ * flips its own `pause` property and keeps it there. Before the fix,
+ * useAudio's signals stayed on "playing" — [Pause] button shown while
+ * silent, a poll that only re-read the same frozen `time-pos` (stuck
+ * waveform), and no way to catch an external RESUME either (the poll was
+ * stopped whenever the UI thought it was paused).
+ *
+ * Integration style (like restore-session.test.ts): real stores and real
+ * persistence files in a temp XDG_CONFIG_HOME — but with the REAL mpv
+ * backend driven over its actual IPC socket. The test flips mpv's pause
+ * property the same way the OS does and asserts useAudio reconciles in
+ * both directions. Skipped when mpv isn't installed.
+ *
+ * Also covers daemon crash recovery: killing mpv out from under the app
+ * must drop the UI out of "playing" (finalizeTrackEnd), and the next Play
+ * press must respawn a fresh daemon and resume audio from the saved
+ * position — the play button may never silently no-op on a dead player.
+ *
+ * Real-timer note: the reconcile path runs on useAudio's real 150ms poll
+ * interval against a real mpv process, with no injectable clock — the
+ * deliberate-exception case from the no-real-timers rule (same as
+ * visualizer-store.test.ts). `waitFor` polls with Bun.sleep.
+ *
+ * Shared-worker note (same as restore-session.test.ts): the suite reuses
+ * bun test workers, so other files' `mock.module("../src/hooks/useAudio")`
+ * leaks into this file's module registry. The REAL useAudio is therefore
+ * imported via a `?external-pause-test` query suffix — a distinct module
+ * identity bun loads from disk, bypassing the leaked mock.

+ * Non-blocking feed refresh tests — task 03 of the bounded-feed-lifecycle
+ * feature.
+ *
+ * Pins the contracts that make a refresh batch feel non-blocking:
+ *
+ *   1. refreshAllFeeds never holds more than FETCH_CONCURRENCY (4) RSS
+ *      requests in flight — a worker pool bounds the batch instead of
+ *      Promise.all firing every feed at once.
+ *   2. Each feed's refreshed episodes are applied AS ITS OWN FETCH LANDS —
+ *      the old Promise.all barrier is gone, so a slow feed no longer hides
+ *      the fast feeds' fresh episodes.
+ *   3. config.json writes are trailing-edge debounced (rapid changes
+ *      collapse into one final write) and flushPendingSave() persists
+ *      immediately, without waiting out the debounce window.
+ *
+ * Polling note (why the polls below use setImmediate, not microtasks):
+ * vi's fake timers trap setTimeout/setInterval/Date/Bun.sleep, so the
+ * debounce is driven with vi.advanceTimersByTime. But a poll loop of pure
+ * microtask turns (`await Promise.resolve()`) can NEVER observe an
+ * in-flight refresh: it keeps the microtask queue non-empty, the event
+ * loop's poll phase is never reached, and Bun.serve never even receives
+ * the fetch (verified empirically). setImmediate is a real macrotask that
+ * fake timers do NOT trap, and it lets the socket I/O progress — each
+ * `tick()` below is one bounded event-loop turn. No real sleeps anywhere.

+ * The episode list cache (what the Feed and My Shows pages show) is bounded by
+ * the user's preference: a date window (default 60 days) or a count (default
+ * 25). The full parse cache holds ALL episodes; fetch-more pages beyond the
+ * bound from that cache (volatile — never written back). These tests pin:
+ *   1. mergeEpisodesBounded unions refreshed episodes with what's in memory
+ *      (fetched copy wins on id collision) and prunes by the supplied keep
+ *      predicate (count or date). Undated episodes are always kept.
+ *   2. The store bounds the visible list by the configured mode, but the
+ *      full parse cache survives — fetch-more pages beyond the bound.
+ *   3. Refresh merge never shrinks the in-memory list except via the bound.
+ *
+ * Clock constraint: these tests run under vi.useFakeTimers, and a LARGE
+ * vi.advanceTimersByTime (past ~5 days of fake time) makes every subsequent
+ * network fetch hang in Bun 1.3.8's fake-timer implementation. The date
+ * boundary is pinned with relative pubDates, never by moving the clock.

+ *
+ * Regression: `enter` on an unsubscribed show's episode result used to
+ * subscribe instead of play — there was no direct "stream unsubscribed
+ * episode" path (subscribing first was the only way to hear it). `enter` now
+ * plays every episode result (matching Feed/My Shows), and the new `subscribe`
+ * action (`a`, sibling of `x` unsubscribe) subscribes the focused result.
+ *
+ * Mounts the real app (sandboxed, silent audio, mocked search store) and
+ * drives the Search tab with the test renderer's mock keys: enter on an
+ * unsubscribed episode plays it without subscribing; `a` subscribes (feed
+ * fetched from a local server); enter then plays the now-subscribed episode.
+ * The search store is mocked so results are deterministic (no directory
+ * network calls); the feed store is real and served from a local HTTP server.
+ *
+ * App modules are loaded dynamically (never statically) because the sandbox
+ * config/data dirs must be set BEFORE they evaluate — their module-level init
