+### Fixed
+- Prevented automatic mail-to-job matching from selecting archived jobs:
+  - Updated `app/job_matching.py` so `find_matching_job()` excludes `jobs.archived = true`.
+  - Applied the same archived filter in the VSPC normalized fallback match path.
+  - This prevents new imports/re-parse auto-approval from attaching messages/runs to archived jobs.
