`[scheduler] task_instance_heartbeat_sec` has no effect in Airflow 3. Every task runs under the task supervisor, which takes its heartbeat interval from `[workers] min_heartbeat_interval`. Nothing reads `task_instance_heartbeat_sec`. The configuration reference still describes it as "The frequency (in seconds) at which the LocalTaskJob should send heartbeat signals to the scheduler". The "Reproducing task instance heartbeat timeouts locally" how-to sets it to slow heartbeats down. The option is removed from `config.yml`. The how-to now sets `AIRFLOW__WORKERS__MIN_HEARTBEAT_INTERVAL` instead. `airflow config lint` and `airflowctl config lint` report the option as removed and point at `min_heartbeat_interval`. Both commands reported the Airflow 2 name `local_task_job_heartbeat_sec` as renamed to `task_instance_heartbeat_sec`. They now report it as removed too. `airflow config update --fix --all-recommendations` rewrote the Airflow 2 name as `task_instance_heartbeat_sec`. It now removes both names. The template default has to go with the lint rule. While `config.yml` defines the option, `conf.has_option` is true on every install. The removal rule would then flag every install. The new parametrized lint tests in `airflow-core` and `airflow-ctl` cover both names. Their assertions fail without the source change and pass with it. related: #58307 --- ##### Was generative AI tooling used to co-author this PR? - [X] Yes (Claude Code, Opus 5.5) Generated-by: Claude Code (Opus 5.5) following [the guidelines](https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#gen-ai-assisted-contributions) --- * Read the **[Pull Request Guidelines](https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#pull-request-guidelines)** for more information.
