fix(server): pause schedules when their destination is archived - #24561
Archiving a thread left its bound schedules enabled. On current main, a 60-second timer failed twice with ThreadManagementThreadArchivedError and scheduled another attempt each time.
Change
Pause bound schedules through the archive effect and stop delivery when the destination is archived or deleted. Preserve the task and its archive reason, leave restored threads paused, and guard completion against tasks rebound while a dispatch is in flight. Timer tasks pause after five consecutive failed dispatches; success or explicit re-enable resets the private persisted counter. Existing schedule spacing applies, and webhook tasks remain exempt from transient-failure exhaustion. Thread deletion keeps its existing cleanup behavior.
Triaged bug via the automated issue flow. GitCafe: #24519.
Verification
The archived/missing-destination regression failed before the fix: four dispatches where one was expected. The rebind regression also failed before its correction. Final focused run: vp test run apps/server/src/scheduledTasks/ScheduledTaskService.test.ts apps/server/src/scheduledTasks/ScheduledTaskService.webhook.test.ts apps/server/src/orchestration-v2/runtimeLayer.test.ts — 148 passed. Implementation validation also passed server typechecking, touched-file lint, and scoped persistence/deletion tests. Both independent second-round reviews returned MERGE.
Server-only change; visual fixture matrix is empty. Real dev-server evidence uses isolated state on Linux, with browser RPC calls through the actual app:

A schedule bound to a thread kept firing after the thread was archived or
deleted, failing every occurrence while staying enabled. Dispatch now pauses a
bound task when the thread is gone, archiving the thread pauses its schedules
through the effect worker, and timer tasks pause after five failed runs in a
row. Restoring the thread leaves resuming to the user.

…d-run
The pause for an archived or deleted destination now applies only while the
task still targets that project and thread, both in the reported task and in
the completion UPDATE. Adds coverage that a success resets the failure count
and that webhook tasks are exempt from the consecutive-failure pause.

A fifth failure from an in-flight dispatch can disable a task that has already been rebound to a healthy destination or converted to a webhook. failuresExhausted uses the stale active snapshot, and markCompleted applies pause without checking the current configuration; revalidate the task’s configuration before pausing it.

Macroscope's review found this PR requires human approval — The change pauses archived-destination schedules and introduces automatic pausing after five failed timer runs, changing existing retry defaults. Human review must confirm that product behavior and resolve the open concerns about rebinding and first-binding archive races.

Scheduled tasks now track consecutive failures and pause under defined failure conditions. Archiving a thread queues an effect that disables scheduled tasks bound to that thread. A database migration adds the failure-count column.

Summary
Failure tracking and retry behavior apps/server/src/scheduledTasks/ScheduledTaskService.ts, apps/server/src/scheduledTasks/ScheduledTaskService.test.ts, apps/server/src/scheduledTasks/ScheduledTaskService.webhook.test.ts, apps/server/src/persistence/Migrations..., apps/server/src/persistence/reconcileV2PreviewMigration.test.ts
Scheduled tasks persist consecutive failure counts. Successes and task changes reset the count. Non-webhook tasks pause after five consecutive failures. Missing or archived destinations disable bound tasks. Tests cover recovery, destination changes, and webhook behavior.
Thread archival queues a replay-safe pause effect. The effect worker calls the resource cleanup service, which pauses tasks bound to the thread. Runtime tests verify that those tasks remain disabled after unarchiving.
Archiving a thread pauses its bound schedules as intended. In a narrow race, where a run is still in flight when the thread is archived and then fails, the visible archive reason can be replaced by the provider error. The task stays paused, so nothing runs unexpectedly. The fix is small and can be made before or shortly after merge.

Explanation
The title "fix(server): pause schedules when their destination is archived" follows the conventional commit format and names the main change. The changeset adds pause-on-archive behavior for bound scheduled tasks through a new pauseForThread operation and the scheduled-tasks.pause effect. The title also omits the consecutive-failure pause and the migration, but those are secondary parts of the same fix and do not make the title misleading.
Full details: Description check
Explanation
The description follows the repository template. It has Problem, Change, Scope, and Verification sections. The Problem and Change sections clearly describe the bug and the fix. Scope links issue #24519 and explains the triage source. Verification lists the focused test command, the observed results (148 passed, a failing regression before the fix), and runtime evidence for the archive, restore, and resume flows. The Verification section does not include a UI screenshot, but the author states that no client rendering changes were made, so none is required. The description also includes a model and harness line, as the template requests. The description has some non-critical verbosity and links to external transcripts that reviewers cannot access in the repository, but it is mostly complete.
Full details: Out of Scope Changes check
Explanation
The changed files support the archive pause and the failure policy from [#24519]. These files include the scheduled-tasks.pause effect type and its executor path, ResourceCleanupService.pauseScheduledTasks, the Orchestrator archive dispatch, the ScheduledTaskService pause and failure-count logic, migration 090 for consecutive_failures, and the tests. The migration registry and preview-migration test expectations change because of migration 090. The MCP toolkit test stub and the GuestShareService test mock add a no-op pauseScheduledTasks or pauseForThread so their test interfaces compile. The PR states it changes no client rendering. Items such as the GitCafe link and the triage note do not change code.
Full details: Linked Issues check
Explanation
[#24519] requires three behaviors that the reviewed head does not fully meet.
Archive: Met. pauseForThread disables enabled tasks bound to the archived thread. It records an archive-related error, keeps the run count, and keeps restored threads paused. The archive effect scheduled-tasks.pause runs through ResourceCleanupService.pauseScheduledTasks. Dispatch checks for archived or missing destinations stop repeated attempts.
Delete: Not met as specified. The PR description says "Thread deletion keeps its existing cleanup behavior." The issue requires disabling bound schedules on delete and preserving a visible retirement reason and delivery history. The raw summary shows no change to the deletion path. The existing deletion-based cleanup removes the task and its history.
Transient delivery retries: Not met. The issue requires backoff plus a finite retry or delivery-age policy, with a terminal failure or paused state. The PR description states "Existing schedule spacing applies," and the summary shows no backoff. The five-consecutive-failure pause applies to non-webhook timer tasks only. Webhook tasks are exempt from transient-failure exhaustion. The issue does not grant that exemption.
Race handling (rebind guard), no replacement thread, and counter reset on success or re-enable are implemented and tested.
Resolution
(a) Change thread deletion so each bound task stays in a disabled terminal state with a visible deletion reason and retained delivery history. Add a test for this path. (b) Add backoff for transient delivery failures. Keep scheduled occurrences separate from delivery retries. Add tests for the backoff and the finite retry or delivery-age limit. (c) Apply the finite transient-failure policy to webhook tasks, or get an explicit requirement change from the issue owner that documents the webhook exemption.

Reset failures on binding changes and guard completion atomically.
saveTask resets consecutive_failures only on a disabled-to-enabled transition. An enabled task can retain four failures when it is rebound, so its first failure at the new destination can pause it.
markCompleted also applies pause: failuresExhausted without checking the current binding. A rebind after findTask returns can therefore let an old run pause the new binding. Check the run binding in the atomic UPDATE before writing the failure count or applying the failure-limit pause.

Renumber the failure-count migration to 081. Main now records a run's
completion in one transaction, so the pause and failure-limit decisions
move into it and read the stored binding there instead of re-checking it
in SQL. A failure counts toward the limit only while the task still
targets the run's destination, and any saved edit restarts the count.

Reconcile archival when binding a first-run thread.
A thread can be archived after its initial message is accepted but before launch returns. The archive effect then misses the unbound task, and bindThread leaves it enabled. A webhook task can remain enabled until another request arrives; restoring the thread can also leave the task enabled.
Reconcile the archive with the first binding, including an archive followed by a restore before binding.

Preserve the archive reason when recording the provider outcome.
If an accepted run finishes after pauseForThread, completion preserves the archive note at Line 1154. The background recordRunFailure can then observe an interrupted or failed provider run and replace that note with only the provider error. The task remains disabled, but its visible archive reason disappears.
Preserve the pause note in this update, as the completion path does. Extend the mid-run pause regression to include the later provider outcome.
