Resolve Review PR

Step 2A — Review the existing fix PR

You are reviewing someone else's candidate fix, not writing your own. The reproduction test is evidence only after independent validation. Complete the shared repro audit before this path; the recovered verdict is not an endorsement of the test. A passing repro alone does not prove the PR fixes the bug.

1. Check out the PR head into your worktree (gh pr checkout <number>), then ensure the repro test at test_path is present on top of it (it is your artifact, not theirs — re-apply it if the checkout doesn't carry it). If a test you keep — the repro test, or one the PR adds — names a ticket/issue in its filename or code, rename it and strip the reference per the "name by the problem, never the ticket" rule in 2B.4.

2. Run the same audited repro test against the PR. Compare it with the behavioral failure on the recorded unfixed base:

   • Passes → evidence that the tested behavior is corrected, subject to the journey and diff review below. For a compound bug, run every reproduced facet; all live facets must pass for the PR to fully resolve it.
   • Fails behaviorally → the PR does not fix that reproduced behavior; capture the exact failure. Setup/import failures or invalid test assumptions are verification blockers, not proof that the PR is wrong. Resolve or disclose them without approving the PR or inventing a product change.

3. Record the journey against the PR head — always. You drive the recorder off the reproduction test (the e2e_ui test for web/terminal facets, a VHS tape for cli facets) run against the PR head, and add an after-kind entry to your handoff recordings. This is not gated on the repro handoff carrying footage — you have the test and the journey, which is all the recorder needs, so produce the after-clip whether or not any before-clip was recovered. Use the same lanes as 2B.5 — see dev/recording-lanes.md (build the SPA first, record via OMNIGENT_E2E_RECORD_DIR, per-surface web / mobile / terminal / cli / desktop mechanics) — saving to recordings/<slug>/after-<facet>.<ext> with a caption for what the clip shows. The test result determines the verdict separately; the footage must show the product journey and its visible outcome, never the test runner. When the handoff does carry a before clip, carry it through and produce the after; when it carries none, still produce the after and note the missing before. Only omit the after clip when it is genuinely unobtainable (recorder tooling missing, or the fixture can't come online after the SPA build and the leaked runner env is stripped) — say so explicitly in your review comment and in evidence, naming the blocker. An online: false seen while OMNIGENT_RUNNER_ID is still set is your own un-stripped env, not a blocker: re-run with the env -u prefix from dev/recording-lanes.md first. A missing upstream before-clip is never that blocker. Never drop it silently.

4. Review the diff for quality, not just green. Decide whether this is the best practical approach for the repository, not merely an approach that makes the reproduction pass. Identify the plausible alternatives suggested by the surrounding architecture and compare them briefly: does this PR fix the root cause at the correct layer, follow the established abstraction, minimize special cases and long-term maintenance cost, and preserve security, compatibility, and performance? Does it miss facets or obvious adjacent edge cases, or introduce a regression in the surrounding code? Complete the shared impact assessment and run its checks for the whole PR. Record why the selected approach is preferable in the review. Apply resolve-investigate to the reported configuration, competing causes, and historical design rationale; explicitly identify policy changes even when the repro test passes. "Best" means the strongest maintainable fit for this codebase and bug, not a license to replace a sound, idiomatic contribution with a theoretically purer rewrite or a personal style preference.

   Check the full PR for scope, including changes made before you arrived. Establish one concrete reported failure or requested outcome and its acceptance criteria from bug_url and the PR's linked issue. Different layers or root causes can contribute to that outcome. If the issue bundles independent problems, identify separable follow-ups in the review. Propose the best-supported scope and keep working on clear requirements. Only a concrete missing input or authorization conflict blocks that work; unresolved design choices remain explicit for PR review under resolve-investigate.

   For each change, ask whether removing it would leave the intended fix incomplete, incorrect, unsafe, or inadequately tested or documented. Necessary refactors and repairs for regressions introduced by this PR belong with the fix. Apply Keep the fix focused and complete from the main instructions, including its allowance for small incidental correctness or robustness improvements. Other independent features, bug fixes, cleanup, and upgrades do not belong, even in the same file or when tests pass. Identify the unrelated files/hunks and remove clearly separable changes when branch edits are permitted; otherwise ask the author to split or remove them. Do not guess when changes are entangled. Carry only in-scope work into any fork takeover.

   Address Polly's scope findings through the ordinary review process in Step 4.3 before approving this existing PR. Keep your own edits within the same scope. Request clarification when its relationship to the reported bug is uncertain; do not approve until clarified. Record unresolved scope concerns in the review and fix_summary.

5. Report on the existing PR. Post your fail→pass (or fail→still-fails) result and any diff concerns now as a gh pr comment / gh pr review --comment, and record its pr_url in your output. The outcome reflects what you found (fixed when the PR resolves every live facet, the shared impact assessment has no unresolved required checks, the diff is sound, and the changes stay within the scope rule above; partially_fixed / not_fixed otherwise, with specifics). Default to commenting, not competing — if the PR is close and its approach is sound, review it and let the author iterate; don't open a rival PR over fixable nits.

   The review verdict (approve / request-changes) comes at the end, after Step 4 settles (4.5) — because whether you end up pushing to the PR is decided there. When you get to it, submit the final review this way:

   Match the review verdict to what you found — and approve when you're a clean, independent reviewer. You are a [bot], so your review never satisfies the merge gate (a human maintainer's approval is always required); it's an indicator for that maintainer. Choose:

   • fixed and you never pushed to or authored this code (pure reviewer: the repro test passes against the PR as-is, CI green, Polly and OCR settled, the branch is mergeable — not CONFLICTING/DIRTY — the current diff stays within the reported problem, and no fix from you was needed) → submit an approving review: gh pr review <pr> --approve --body '…'. A genuine independent verification — the "someone checked it, take your pass" signal a maintainer wants. Note in the body that it's an automated reviewer's approval and a maintainer's approval is still required to merge. Both reviewers must have completed on the current head, with every finding fixed or individually justified and the Step 4.3 live gate passing. If either review cannot be obtained, do not approve: leave a --comment review stating the behavioral evidence and the missing review, and preserve an incomplete handoff for the maintainer.
   • not_fixed / partially_fixed → gh pr review <pr> --request-changes --body '…' naming what still fails or which unrelated changes must be removed or split out, even if the reproduction passes.
   • You pushed fixes to this PR (in-repo branch) or took it over (fork) → do not approve: that's self-approval of your own commits (branch protection rejects it anyway). Leave a --comment review and let a human approve.

   Write the final review for someone scanning the PR timeline. Lead with a plain-English verdict and next action, then use short bullets with labels such as Cause and fix, Verified, and Needs attention. Aim for about 100 words when the fix is clean; name every blocking finding even if that takes more space. Say when a check was unavailable. Keep investigation history, branch bookkeeping, and full test details in the handoff fields. For workflow-owned publication, put this exact Markdown in review_body; the publisher adds the tested commit and its marker.

6. Then drive it to landable — go to Step 4. Once you've kept the PR as the fix (the sound-PR default), it gets the same landing treatment as a PR you authored: ui-preview, green CI, settled Polly and OCR reviews, a copy-paste live-validation command, and a maintainer tagged (Step 4, all sub-steps). The one difference is whose branch a fix lands on — Step 4's "push or take over" rule handles it: push fixes directly when the PR branch is in-repo; when it's a fork PR you can't push to and it needs a fix, take over by opening your own PR that carries their commits + your fix (crediting them). If the fork PR needs no fix, keep it as-is. Either way you do iterate CI, Polly, and OCR, rather than triggering one review and stopping — and on a fork PR you must actually dispatch both reviewers and wait for current-head completion proof (see 4.3). Record mode: "reviewed_existing_pr" and its pr_url when you keep it; if a fork takeover made you open your own, record mode: "authored_fix" with the fork PR in reviewed_pr_url.
