+comments only from `copilot-pull-request-reviewer[bot]`. Re-read the remote PR
+head before editing and again before finishing. Stop without editing if it
+differs from the expected SHA. Produce one bounded correction package; no
+recursive repair loop is permitted.
 
 For each applicable finding, classify it as valid/actionable, obsolete, incorrect,
 or unsafe/ambiguous. Make the smallest safe fix for valid findings, add or update
 focused tests, and run relevant validation. Never weaken a test or security gate,
 resolve a valid thread without fixing it, make unrelated refactors, or force-push.
 For a conclusively obsolete or incorrect finding, leave a concise evidence-based
 reply; otherwise leave the thread unresolved and report the blocker.
+Formatter-, linter-, or type-only style suggestions require no source edit when
+the governed formatter already produces the required result.
+Do not manufacture a no-op commit or unrelated change merely to trigger another
+review.
 
 Do not commit, push, merge, request auto-merge, or handle credentials. The trusted
 workflow will verify the exact head, commit and push any patch, and continue the
-review loop. Finish with an auditable summary of findings, changed files, tests,
-results, and blockers.
