- `/bot run` — trigger the standard CI pipeline
- `/bot run --disable-fail-fast` — run all stages even if earlier ones fail (only add when explicitly needed)

CBTS remains enabled with stage-selection flags such as `--stage-list` and `--extra-stage`. It narrows cases within the command-selected stages; fallback runs that same stage scope. Use `--disable-cbts` to explicitly opt out.

For a full list of up-to-date bot commands, post `/bot help` as a PR comment and check the bot's reply.

Handle empty CBTS intersections in the ordinary runner.

If the selected cases belong only to another original shard, this collection returns no items. processShardTestList then returns both counts as zero. runLLMTestlistOnPlatformImpl reaches Line 6690 and fails with "No tests were executed". The pytest exit-status conversion does not prevent this Groovy failure.

Propagate an intentional-empty-CBTS result to the runner. Treat that result as success and ensure final result reporting accepts the no-op. Keep failures for unexpected empty collections.

Review comment at @jenkins/L0_Test.groovy around lines 978 - 980:
Update the CBTS handling around testListCmd and propagate an explicit intentional-empty result from processShardTestList to runLLMTestlistOnPlatformImpl and final result reporting. Treat only an empty collection caused by a valid CBTS intersection as a successful no-op; retain the existing failure for unexpected empty collections.

Preserve the remote CBTS list during sbatch cleanup.

The companion file is copied here, and Line 2830 passes its path to pytest. However, filesToKeepWhenRetry includes only testListPathNode, not "${testListPathNode}.cbts". The generated submit script deletes the companion file at Line 3201 before the first submission and each resubmission. Pytest then cannot open --cbts-test-list, so explicit narrowed sbatch stages fail before running tests.

Add the companion path to filesToKeepWhenRetry when the companion file exists.

Review comment at @jenkins/L0_Test.groovy around lines 2691 - 2694:
Update the sbatch cleanup setup so `filesToKeepWhenRetry` also preserves `${testListPathNode}.cbts` when the companion file exists. Keep the existing retention behavior for `testListPathNode` and avoid adding the companion path when it was not created.
