matrix_service: remove done_callback that modified _tasks without the lock. Move _tasks.pop into _run_pipeline's finally block under _lock, consistent with how _run_revalidation handles its own cleanup. export_service: remove redundant path-traversal guards from _sanitize_filename. The preceding [^\w\s-] regex already strips '.', '/', '\' and all other non-word, non-whitespace, non-hyphen characters, making the explicit replace calls unnecessary. https://claude.ai/code/session_01REMaPSNwgoeDLBBAiG2EBw

Code Review
This pull request addresses review comments from a previous PR. In matrix_service, it correctly moves the cleanup of _tasks into a finally block under a lock, fixing a race condition and improving consistency. In export_service, it removes redundant path-traversal guards, simplifying the code. The changes are solid improvements. I have one minor suggestion to improve a comment's accuracy in matrix_service.py for better long-term maintainability.

There was a problem hiding this comment.
This comment is slightly misleading. While both _tasks.pop and _queues.pop are individually protected by the lock, they are not performed atomically together due to the asyncio.sleep(2) between them. During this 2-second window, the state is inconsistent (is_generating() would be false, but queues would still exist).
A more accurate comment would clarify the two-step cleanup process and why the delay is necessary.
| # Remove the task entry and clean up subscriber queues. | |
| # Both happen under the lock so readers see a consistent state. | |
| # The delay allows clients to receive the final SSE event before the | |
| # queue is torn down. | |
| # The task is removed first, marking generation as complete. | |
| # Then, after a delay to allow final SSE events to be sent, | |
| # the subscriber queues are cleaned up. Each operation is | |
| # performed under the lock for thread-safety. |
