fix(web): queued messages send while their thread is not open - #13764
Conversation
Only the mounted ChatView drained the queue, and only one ChatView is mounted at a time. A message queued on thread A sat idle after switching to thread B, and went out only on return. A root-level QueuedMessageSender now watches every thread that has a queue and sends through one shared sendQueuedMessage, used by both the watcher and Send now. Queued messages carry the model and modes from queue time, so the send no longer reads the live composer. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This change adds a root-level watcher that can dispatch queued agent turns for threads that are not open, along with a substantial new upload, settings, dispatch, retry, and queue-lifecycle path. Because it changes production send behavior across all queued threads rather than making a small isolated correction, human review is warranted. You can add or adjust custom eligibility rules.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick winCheck cancellation before persisting queued settings.
Attachment preparation can yield while the message is
"preparing". Stop can drain it during that time, but the settings commands still run beforemarkDispatchingreturnsfalse. The canceled message can therefore persist model or mode updates without starting a turn.Add a live queue-state check after attachment preparation and before the first settings command. This fixes the Stop-during-attachment trigger. It does not undo a settings command already submitted; a complete fix for that window requires cross-boundary cancellation or transactional server changes.

Merges origin/main (95030dc), the 18 commits after a21b42c. Conflict resolutions that change V2 code: - AgentAwarenessRelay: keep V2's publish worker and drain, add main's unlinked backoff and requestCatchUp (cloud/http now wakes it). Main's catch-up tests are rewritten against V2's relay harness. - server.ts: keep V2's MCP route wiring, add main's untracedRequestsLayer last. - Sidebar: V2's sortSettledThreadsForSidebar is dropped for main's shared sortSettledThreads (client-runtime, same resolver); its tests moved there and use V2's latestRun. - #13767 cache encode shortcut: not taken. It relies on V1 shells being in encoded form; V2 shells hold DateTime values and V2 already encodes cooperatively (mobile shell-cache-encoding, #12117). Main's IndexedDB "abort" listener fix is kept. - #13764 queued sends: main's client-side QueuedMessageSender and queuedMessageStore stay deleted; V2 queues runs on the server (Orchestrator startNextQueuedRun), which already drains unopened threads. - #13765 / #13756: V1 ProjectionSnapshotQuery and ProjectionPipeline keep V2's versions except main's skip of empty attachment-cleanup spans. - Docs: composer.md keeps V2's queue text; keybindings.md adds usagePageOpen to V2's list. - Deleted-in-V2 V1 files that main modified stay deleted.

A message queued while the agent works only went out if its thread stayed open. Switch to another thread and it sat there until you came back, so all the time away was lost.
Root cause: the queue store is global, but only the mounted
ChatViewsent from it, and only oneChatViewis mounted at a time. The send path also read the model and modes from the live composer, which does not exist for a thread you are not viewing.Fix
QueuedMessageSender, mounted once at the root, watches each thread that has a queue. Reading the thread keeps its detail subscribed, so it sees tool boundaries and the end of the turn on web and desktop. It waits on the same gates as before: connection, live detail, rewind, approvals and questions.sendQueuedMessageis the one send path for queued messages. The watcher and Send now both use it.ChatView.onSendno longer has a queued-message mode (about 100 lines removed).drainGenerationcounter.hasServerAcknowledgedLocalDispatch, so two messages do not leave on one boundary.This supersedes #13122, which fixes the same bug with a second send path next to
ChatView's. Here there is only one path.Closes #13676. Closes #13319.
