Callback triggers could be claimed by another healthy triggerer because their assignment query omitted the live-owner filter used for task and asset triggers. Repeated claims could duplicate callback execution and use selection capacity needed by waiting triggers. Apply the same unassigned-or-unhealthy-owner filter to callbacks. Regression coverage verifies stable ownership across two healthy triggerers while unassigned callbacks and callbacks owned by stale or finished Jobs are claimed, for both default and named queues. Validation: - Both new regression cases fail before the fix. - Trigger model suite: 46 passed on PostgreSQL 14 and 46 passed on MySQL 8 through Breeze/Python 3.10. - Triggerer suite: 112 passed with SQLite through Breeze/Python 3.10. - Regular and manual prek checks passed, including Ruff and airflow-core mypy. Selective checks request the full core CI matrix, which was not run locally. An initial combined PostgreSQL model/triggerer run exited with code 137 in the 2 GB Docker environment; the separate suites above completed successfully. --- ##### Was generative AI tooling used to co-author this PR? - [X] Yes — Codex (GPT-6) Generated-by: Codex (GPT-6) following [the guidelines](https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#gen-ai-assisted-contributions) -- This is an automated message from the Apache Git Service.
