fix(web): keep queued threads subscribed - #15293
ANSHSINGH050404 wants to merge 2 commits into
Conversation
The keep-alive check only treated preparing, starting, and running as active, so queued and waiting threads closed their detail stream while the composer still showed working. Include queued and waiting to match run status and phase mapping.

ApprovabilityVerdict: Approved at Macroscope's review found this PR approvable — This is a narrowly scoped web bug fix that keeps queued and waiting thread detail streams mounted, matching the app’s existing active-status handling. The production change is isolated to one predicate and includes regression coverage for both statuses, with no API, schema, deployment, or configuration impact. You can add or adjust custom eligibility rules. Learn more. |

Narrowed per triage: keep-alive is desktop-Electron only and waiting is a short post-success state. Queued shell status still needs to stay mounted so a desktop connecting while a follow-up is queued behind an active run pre-mounts instead of snapshot-loading.

Keep waiting threads subscribed.
RunningThreadKeepAlive runs in Electron, but isRunning excludes waiting. A live detail with a waiting run is therefore treated as done, so its stream can close before later waiting-state updates arrive. The server classifies waiting as active, and the web UI presents it as working. Include waiting in this predicate.

A desktop connecting while a follow-up turn is queued behind an active run does not pre-mount that thread, so the first open snapshot-loads instead of reusing a live stream. Keep-alive keys off the shell latest-run status, which reads queued in that state.
Includes queued in the keep-alive active check. Waiting left out per triage: it is a short post-success state until checkpoint capture commits, not a live session.
Verification: apps/web src/state/threads.test.ts keeps a queued shell thread open. Web unit run in this checkout: 7 files passed, 67 tests passed.
