CCC

Added

• Added a duplicate-repo instance guard: on startup the dashboard now checks the peer registry for another live CCC server whose git common-dir matches its own (identical across worktrees of one repo) and refuses to start, printing the offending pid/install path/port. This catches the "forgotten python3 server.py from a worktree" case — observed as a day-old instance leaking app-server children and writing into the shared activity log — while leaving legitimate multi-repo peers untouched. Override with CCC_ALLOW_DUPLICATE_REPO=1 or CCC_EPHEMERAL=1 for intentional second instances. Registry entries now record repo_common_dir, and stale entries held by recycled pids are verified by argv before being treated as duplicates.
• Add an Annotate control to the queue-first view so UI feedback can be captured without returning to sessions.
• Worker upgrades now actually take effect: run.sh compares the persistent worker's loaded server.py version (new server_version field in the worker health response) against the repo on every launch and kickstarts the worker when they differ. Previously the "never restart a healthy worker" policy meant code fixes in worker-owned paths (like the Codex app-server liveness probe) never reached upgrading users until a crash or reboot. Queued work from the restarted worker shows as "needs reconciliation" and is reclaimed with one click in Settings → Maintenance.

Fixed

• Keep Coding, Workers, and Messages selectable while filtering All sessions by Claude, Codex, or Kimi.
• Fixed the Codex app-server WEDGED-and-respawn churn (up to every ~45s). Root cause, confirmed by full-lifecycle tracing: the liveness probe treated any reply without a "jsonrpc" envelope key as fake — but this app-server omits that key from responses, so every probe "failed" in ~0.5s on a perfectly healthy server, and each WEDGED replacement needlessly killed the app-server (and any live turn on it). The probe now accepts any genuine reply (result, or a protocol-level error without the synthetic fallback marker). Supporting hardening from the same investigation: any recent channel traffic now counts as proof of life (probe skipped entirely), a failed probe defers replacement while a tracked turn shows fresh activity, _log_activity's per-call mkdir is cached, liveness logging no longer runs under _CODEX_APP_SERVER_LOCK, and a permanent JSONL firehose (logs/app-server-trace.log) traces every probe stage, request, reader event, and liveness decision.
• Throughput page: the Codex weekly burn chart no longer collapses to the raw 14-day view when a refresh lands while the Codex usage snapshot is stale; the chart now shows 7 days of history and at most 2 days of forecast; the selected engine tab survives reloads; and the 48h zoom (+) switches to 1-hour columns.
• Add a separate configurable reasoning-effort default for WatchTower workers.
