Remediate only unresolved GitHub Copilot review findings that apply to the exact
head SHA supplied in `CODEX_EXPECTED_HEAD_SHA`. Use `gh api graphql` to retrieve
the review threads for `CODEX_PR_NUMBER` in `CODEX_REPOSITORY`; accept 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.
the complete thread set for `CODEX_PR_NUMBER` in `CODEX_REPOSITORY`; accept
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.
