Add sync-label check: PRs need the maintainer-applied 'sync' label#1473
Merged
Conversation
This repo is a read-only mirror of the internal source of truth; the only PRs that should merge are release syncs. The check fails unless the PR carries the 'sync' label (triage+ permission to apply), so a merge always requires a deliberate maintainer act. Temporary until release automation takes over merging.

The label gate runs at PR level (required checks must pass to enter the merge queue). Without a merge_group trigger, a required sync-label check would never report on queue groups and stall every entry. Signed-off-by: Hector Castejon Diaz <hector.castejon@databricks.com>

What
A required-check candidate that fails unless the PR carries the
synclabel. The label needs triage+ permission, so external contributors can't self-apply it — and maintainers must perform one deliberate act before a PR becomes mergeable, which is exactly the accidental-merge failure mode this guards against. Replaces the old[sync]-in-title convention (titles are author-controlled, i.e. spoofable).The error message routes non-sync PRs to CONTRIBUTING.md's mirror flow.
Temporary: goes away once release automation owns merging.
Try it
This PR itself is the test: the
sync-labelcheck should be failing right now. Applying thesynclabel should turn it green (thelabeledevent re-runs it); removing the label flips it back.Follow-ups (not this PR)
