Summary
For pull request events, Gitea reads workflow definitions from the pull request head and posts a synthetic skipped status when workflow branch or path filters exclude execution. A fork pull request author can supply a workflow matching a required status context but deliberately prevent it from running. Because skipped statuses count as success, branch protection or organization-required workflow checks can appear satisfied without the mandated workflow executing; no runner or maintainer approval is required for this path.
