Local Codex Review (pre-push)

Runs the exact same review Codex performs in CI (.github/workflows/codex-pr-review.yml), but locally and scoped to work you have not pushed yet — so you catch what CI would flag before the PR exists. Use this before git push on a non-trivial change.

Correspondence with CI — identical:

• Policy: REVIEW.md (severity triage, public-surface checklist, AGENTS.md compliance, test coverage).
• Model: gpt-5.6-sol, model_reasoning_effort="xhigh".
• Output: markdown starting with ## Codex Review, findings tagged P0 / P1 / P2 with file:line.

Differences from CI — local-only:

• Scope is the current branch vs main at the merge-base, including uncommitted changes (CI reviews a pushed PR diff).
• Sandbox is read-only (CI uses danger-full-access on an ephemeral runner). Codex reads the diff and files but cannot modify your working tree.
• Fresh context is inherent: codex exec is a separate cold process, so it does not anchor on the current chat session — the same reason local-review insists on a subagent.
