TL;DR: adds the same advisory Codex PR review that noise, gatorStats and rpc-proxy already run, so every PR here gets an independent review comment. Nothing about how this repo builds or deploys changes, and it never blocks a merge. Your call on merging.

Why

Our SOC 2 Type II auditor tests that each production code change has an independent review. This repository is one of five without the Codex reviewer, so its PRs show no recorded review (VGTR-2539).

What

  • .github/workflows/codex-review.yml: runs Codex on each non-draft PR from this repository and posts the result as a PR comment. Advisory only (no fail step). Actions pinned to the same commit SHAs as noise; fork PRs and Dependabot are skipped.
  • .github/codex-review-prompt.md: a short repo-specific rubric (bugs, security, operational risk; no style comments; No findings. when clean).
  • The OPENAI_API_KEY repository secret is already set (same key as ai-dan), so the review runs on this PR itself.

Every pull request gets an independent Codex review posted as a PR comment,
the same pattern as noise, gatorStats and rpc-proxy. Advisory: it never
fails the check. Supports the SOC 2 CC8.1 change-review control.

Heads-up: I'm merging this for the SOC 2 audit window (closes 2 Nov) so this repo's PRs carry a recorded independent review. It's the same advisory Codex review that noise and gatorStats already run: it posts a comment and never blocks a merge. Happy to revert or adjust if you'd like it different.

Commenting on a pull request with only issues: write returns 403 (Resource
not accessible by integration), so the post_feedback job needs
pull-requests: write. Reverts the previous commit's permission change.

🤖 Codex Review

Low: .github/workflows/codex-review.yml:57: issues: write already authorizes issues.createComment; remove the redundant pull-requests: write permission to limit the token’s access.

…VGTR-2539)

Records why the comment job keeps both issues: write and pull-requests: write
(issues: write alone returned 403) and why the pull_request secret exposure
is an accepted risk (write access already grants secret access; forks are
excluded; only the two principals have user write access). Addresses the
Codex review findings.

🤖 Codex Review

High: .github/workflows/codex-review.yml:54: The job passes the OpenAI key while running the PR merge commit’s editable workflow and prompt, allowing a same-repository PR to direct Codex to expose the key; run the secret-bearing job only on trusted code or use an isolated, scoped credential.

Accepted risk, documented in the workflow header. In GitHub Actions, write access already grants access to repository secrets (any branch push can run a workflow that reads them), so this trigger adds no exposure. Fork PRs are excluded by the head-repo guard, and the only user accounts with write access are the two principals. Hardening across all Codex workflows (a scoped key or a trusted-workflow design) is tracked in VGTR-2539.
