New: sharding. Add shard-count (2–40, grep/affected modes) to run tests in parallel across shards and merge into one Checksum run. See the README "Sharding" section.
New output: verdict. The exit code now gates on the server-computed verdict (pass/fail) rather than the raw status string — correct for sharded runs, empty selections, and infra failures.
- An empty test selection (grep matched nothing) now fails the step instead of passing.
wait: truenow polls the run-status endpoint by run id instead of by job name.test-run-idis now set at dispatch (previously only after a terminal status).- A
404from the status endpoint now fails fast instead of retrying.
Pin @v1 for the old behavior; move to @v2 to adopt the above.
