Removing a worktree archived its sessions one SDK call at a time and then re-rendered the whole sidebar once per streamed session.updated echo. On a worktree with 121 sessions that meant 14.8s of main-thread work, 121 requests, and 328 localStorage writes. - Add POST /api/openchamber/sessions/archive: validates a batch (max 500 ids, per-request archivedAt), archives sequentially, and reports partial failures instead of dropping the batch. VS Code serves no such route and answers 501; the shared UI then falls back to the per-session path. - Plan batches from the sessions this client actually holds, live directory stores first, so worktree-only sessions still batch. - Claim (id, archivedAt) pairs before the request and consume the matching session.updated echoes, so the server's own confirmations no longer fan out into 121 store publications. Runtime-scoped, TTL 30s, released on response or fallback; non-matching updates pass. - Make the managed-chats persistence a real trailing debounce instead of a 50ms throttle, so a burst of publications coalesces into one localStorage write. Benchmark (121 sessions, production build, real Chrome): 14785ms -> ~1030ms, long tasks 100 -> 1, global store publications 236 -> 1, persistence writes 328 -> 3.
