The queue/scheduler lived only in renderer memory, so saved/scheduled and other pending downloads were silently lost on quit (audit M4). Persist them: - main: queue.ts store (proven cached-atomic createJsonStore, queue.json) + queue:list / queue:save IPC; QUEUE_MAX cap. - shared: PersistedQueueItem = the durable subset of DownloadItem (runtime-only progress/speed/eta/sizeLabel/finishing dropped). - renderer: mirror the persistable items on every queue change (a signature over the subset means progress ticks don't re-save; main's jsonStore coalesces the writes) and rehydrate on launch via an App useEffect. Pure mappers extracted to store/queuePersist.ts and unit-tested. Restore semantics: downloading -> queued (yt-dlp continues the .part), saved + scheduledFor survives so the promoter fires when due, paused/error return actionable; completed/canceled are never persisted. A queueHydrated gate stops a launch-time store change from wiping queue.json before it's read. Reconciles ROADMAP.md. typecheck + 268 tests + eslint + prettier green. (OS-level quit/relaunch cycle is worth a manual smoke test.) Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
