Only one task dev server ran at a time. Main was stopped before PR startup.

Repo Playwright + /usr/bin/google-chrome, actual app UI, real Codex gpt-6.1-sol.
Created project pointing to /home/user/t3code through Add project > Local folder.
Created conversation through composer. No mocks, Replay, fixtures, or synthetic DB rows.
main online response: ONLINE-READY
main disconnected: Environment disconnected (disabled). Enter retained prompt and showed
Not connected: message not sent / Reconnecting to the environment. Try again once it is connected.
PR disconnected: 1 queued offline / Sends automatically when connected.
Reconnect produced actual Codex response OFFLINE-DELIVERED and emptied local queue.
Online follow-up produced ONLINE-FOLLOWUP.
Queued PERSISTED-FOLLOWUP, navigated to about:blank to unload app while offline,
restored network and opened same thread: actual Codex response PERSISTED-FOLLOWUP.
Sole canceled draft: reproduced missing replacement sidebar row before fix.
After fix: replacement sidebar row appears, reopens, and Codex replies REPLACEMENT-READY.
Both Cancel handlers activated for first+follower in one task: queue emptied;
replacement draft reopens and Codex replies CONCURRENT-CANCEL-RECOVERED.
Final source: queued plan then build through actual composer. Server persisted
598 thread.interaction-mode-updated plan; 600 run.created starting;
608 thread.interaction-mode-updated default; 609 run.created queued.
Actual Codex replies: RECEIPT-PLAN-READY and RECEIPT-BUILD-READY.
Retained the actual UI-created plan queue record and replayed it through the
client outbox after the later build command, simulating a lost acknowledgement.
Historical-mode wait (89dd214b36): Thread settings have not synchronized.
Receipt-sequence wait (final): deliverOfflineMessages resolved, outbox empty.
Read-only server count of run.created for original messageId: 1 (no duplicate).
Final online follow-up: FINAL-ONLINE-VERIFIED.
Observed actual outbox writes for DURABLE-SKIP-READY: initial delivery persisted
modeChanges {runtime:false, interaction:false} before sending.
After a newer online plan selection, replayed this accepted record:
old d3a738f5d7 overwrote plan with default (event 905).
Final source after another real online plan selection (event 908): replay clears
outbox, leaves plan selected, and produces no new mode event.

blacksmith-check: vp run check:changed verification/baseline
pass format, lint, knip, GraphQL, typecheck (36 packages),
206 tests across 13 files, React Compiler checks (14 files).

Running server, actual client command via serverEnvironment.captureHostScreen:
Failure > HostScreenError { reason: unsupported } (expected on Linux).
