The release tag must point at the commit the artifacts were built from (github.sha). The step tagged whatever the job checkout resolved to - the branch head at job START - so a commit pushed to main mid-run moved the tag target; when that head commit happened to touch .github/workflows/, the GitHub App token's tag push was rejected outright (refusing to create refs at workflow-modifying commits), failing the 0.8.0 draft.
