Release PR Gates

Verify required CI checks are green on the trunk, then cut a release (semver tag + GitHub release) or open a release PR targeting the default branch. Staging and production are deployment environments driven by CI/CD and tags — not long-lived branches.

Delivery Readiness

For every implementation PR, resolve the installed executing-plans skill and read its references/delivery-gate.md before declaring merge-ready, merging, or reporting Done. This is the canonical delivery contract; local menus and playbook shortcuts do not weaken it.
