fix(ci): add pr-review.yml to .prettierignore and use GH_PAT_WORKFLOWS for autofix pushes - #627
The org-standard pr-review.yml caller stub synced from combsmith/.github must not be reformatted by Prettier, which would collapse the two-space gap before # NOSONAR markers and reflow comments, re-introducing byte-identity drift.
In .github/workflows/ci.yml, running npm ci, npm run format, and npm run lint -- --fix alongside a persisted push credential exposes the token to PR-controlled tooling/hooks, while pushing auto-fixes with GITHUB_TOKEN does not trigger follow-up CI checks on the autofix commit.
Solution
Document and preserve .github/workflows/pr-review.yml in .prettierignore alongside the other standards-owned verbatim workflow stubs.
Split CI auto-fixing in .github/workflows/ci.yml into two isolated jobs:
autofix (contents: read, persist-credentials: false): runs npm ci, npm run format, and npm run lint -- --fix, stages only tracked non-workflow files (git add -u -- . ':(exclude).github/workflows'), exports the binary patch, reverts unstaged edits (git checkout -- .), verifies npm run check against the staged tree, and uploads the patch artifact along with head_sha.
autofix-push (contents: write, persist-credentials: false): performs a clean checkout with no npm scripts or PR hooks, verifies GH_PAT_DON_PETRY || GH_PAT_WORKFLOWS is configured and the PR branch head still matches head_sha, validates via NUL-delimited pre-apply (git apply --numstat -z) and post-apply (git diff --cached --name-only -z) guards that no .github/workflows/ paths are touched, and commits/pushes to HEAD:refs/heads/${HEAD_REF}.
Verification
npm run check passed
npm test -- --coverage and node scripts/check-coverage.js passed

Chores
Automated formatting and lint fixes are now applied through a separate, permission-limited process. Fixes are pushed only if the pull request has not changed during processing, and changes to workflow files are not pushed.
Updated the formatting configuration’s note about a protected workflow file to clarify why it must remain unchanged by formatting. This does not change the behavior of the application.

Code Review
This pull request updates the .prettierignore file to exclude the .github/workflows/pr-review.yml workflow file from Prettier formatting. This ensures that the exact byte-identity of this standards-owned caller stub is preserved, preventing any formatting drift. There are no review comments, and I have no feedback to provide on these changes.
@don-petry I received your request but all AI engines are currently rate-limited. I'll retry automatically once the rate limit clears.

It is labeled needs-human-review (flagged for human review — this label is applied by automation as well as by people, so an item can become held without anyone noticing), so dev-lead will not pick it up while that label is present. This notice is posted once so the withhold is visible rather than looking like a stalled run.
To re-enable automated pickup: remove the needs-human-review label.

Block workflow-path renames before the patch export.
git add -u -- . ':(exclude).github/workflows' does not remove workflow entries that are already staged. PR-controlled tooling runs before this step and can stage git mv .github/workflows/a.yml src/a.txt. The export then emits a rename whose source is a workflow file. Both consumer guards check only the destination path, so they do not reject it. The autofix-push job applies the patch and pushes it with the PAT, which removes a workflow file.
Fail the export when the index contains any workflow path:

The pathspec limits rename pairing to .github/workflows. A staged rename therefore appears as a deletion of the workflow source, and the check fails. The check runs before git add, so it also covers a workflow change staged by an earlier tool step.
Whether the removed workflow reaches the branch depends on the PAT's scopes and the branch protection rules. This review did not check either one. The guard exists to block this path, so the bypass is still a defect.
