Add episodeCacheMode/count/days preferences (default: date, 60 days).
Apply the bound when reading instead of writing, so a preference change
takes effect without a refetch; the full parse cache stays intact so
fetch-more can page beyond the bound. Thread the window through
load/saveFeedsToFile and update tests and task docs.
Persisted feeds keep only episodes from the last 30 days (plus completed
downloads); older episodes live in volatile memory and survive refreshes
via union merge, with per-feed in-memory caches capped at 500. Refresh
batches run at FETCH_CONCURRENCY=4 with per-feed incremental apply (no
Promise.all barrier), config.json writes are trailing-edge debounced
(250ms, immediate flushPendingSave for unsubscribes), and cold
fetch-more refetches abort at FETCH_TIMEOUT_MS. A shared activity store
powers a global top-right indicator covering refresh, fetch-more,
subscribe, search, and downloads.
Also includes the in-flight incremental RSS parsing (chunked with
event-loop yields) and refresh spinner work this tree already carried.
The verification gate found that Task 04's core deliverable was never
implemented: Player and Search pages are not routed through <YaziPaneRow>,
so Player renders a single full-width column and Search's three columns
sit at equal thirds (31/32/31) instead of the target 1:3:3 ratio
(~14/43/43).
- Mark task 07 status BLOCKED with a pointer to the blocker evidence
- Add 07-blocker-task-04-player-search.md documenting the missing
implementation, evidence (player/search harness frames), failing exit
criteria, and a fix plan for the task 04 do-over
