📝 WalkthroughWalkthroughThread deletion now removes the deleted thread’s provider-session binding after stopping its provider session. The provider session directory adds persistence-backed removal, and affected test doubles implement the expanded service interface. ChangesThread binding cleanup
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to Thread deletion now cleans up provider bindings, but the cleanup-order test does not verify that terminals close after binding removal. The implementation is otherwise ready, with a bounded test-coverage gap that could allow a future ordering regression. Sequence Diagram(s)sequenceDiagram

ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This localized fix removes persisted provider bindings during thread deletion, but the asynchronous cleanup may race with a recreated thread using the same ID and delete its replacement binding. The current test covers only the normal deletion path, so the ordering risk requires human review. You can add or adjust custom eligibility rules. Learn more. |

Retry can lose new provider binding
Medium Severity
Draft retries reuse a soft-deleted thread id. forgetProviderBinding always calls remove on the async deletion worker and does not check for a later thread.created. If the retry upserts a binding before that worker finishes, the new provider_session_runtime row is deleted and later routing cannot find a session.

Dismissing prior approval to re-evaluate f857df8
The provider runtime table keeps one row per thread that has ever run an agent, and nothing pruned it. A deleted thread kept its binding for the life of the install, so the table grew without bound and every full scan of it paid for threads the user removed long ago. The thread deletion reactor now removes the binding after it stops the provider session. The order matters: stopping a session ends in a directory upsert, so removing first would re-insert the row this cleanup exists to drop. Removal reuses the repository's existing `deleteByThreadId`, which until now had no production caller, and failures are logged like the reactor's other cleanup steps rather than failing the deletion.

Problem
Deleting a thread stopped its provider session and closed its terminals, but left the row in
provider_session_runtime. Nothing else prunes that table:ProviderSessionDirectoryhad no delete method and nothing called the repository'sdeleteByThreadId. The rows accumulated for the life of the install, including rows for threads the user had deleted.Fix
Add
removeto the session directory and call it from the thread deletion cleanup, alongside the existing session stop and terminal close. It uses the same cleanup-failure logging as its neighbours, so a persistence failure does not abort the rest of the deletion.Verification

Note
Low Risk
Localized cleanup on thread delete with existing non-fatal error handling; no change to session start or reconciliation behavior beyond pruning stale bindings.
Overview
Thread deletion previously stopped the provider session and closed terminals but left rows in
provider_session_runtime, so bindings for deleted threads could accumulate indefinitely.This PR adds
ProviderSessionDirectory.remove, implemented via the repository’sdeleteByThreadId, and wiresThreadDeletionReactorto call it after stopping the session and before closing terminals. Failures use the samelogCleanupCauseUnlessInterruptedpath as the other cleanup steps so a persistence error does not block the rest of deletion.Test doubles gain a no-op
remove, andThreadDeletionReactorgains a test that asserts the deleted thread id is passed toremove.Reviewed by Cursor Bugbot for commit 9e24e03. Bugbot is set up for automated code reviews on this repo. Configure here.
