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.
