nit: the "oldest review in the round" invariant only holds for rounds with ≥2 reviews (not blocking).

The comment above states it unconditionally — "its oldest review is the tree that round actually started from" — but when a round's only review is its terminal one, the oldest review is the terminal review, so .[0].commit_id is the head-at-submit-time again and the straddle hole reopens:

COMMENTED  @aaa
DISMISSED  @aaa     <- round 1 terminal
APPROVED   @ccc     <- round 2: read bbb, approved after a push to ccc

$done = [1,2], start = $done[-2]+1 = 2, slice = [APPROVED@ccc], base = ccc. bbb...ccc is reviewed by nobody.

Both halves of that conjunction are already in your own captured data. reviews-straddled-round.json has the straddle (comments on a89f19e8, approve 5s later on 951c8afa), and the same fixture has a single-terminal-review round at index 6 (DISMISSED@951c8afa at 19:07:06, a separate id from the APPROVED@951c8afa at 19:00:35 — a round that approved with no inline comments). So the shape needing both is rarer than what you fixed, not hypothetical — a clean approve is the common outcome per the Decision Framework, and the straddle window is the same seconds-wide one.

The fallback direction you chose makes this cheap to close: treat a last-finished round of length 1 as untrustworthy and step back to the previous round's window (or return "" and take the full diff). Either way it'd be worth a fixture, and worth softening the comment so the invariant reads as conditional on the round having a non-terminal review.

nit: still open from the last round — the "oldest review in the round" invariant only holds when the round has a non-terminal review (not blocking).

Verified against your own fixture. Truncating reviews-straddled-round.json to the first seven reviews (round 1 = 5 × COMMENTED@a89f19e8 + APPROVED@951c8afa, round 2 = the single DISMISSED@951c8afa, a distinct review id) gives:

done   = [5, 6]
window = ["DISMISSED@951c8afa"]
base   = 951c8afa

When a round's only review is its terminal one, .[0] is the terminal review, so the base is head-at-submit-time again and the straddle hole this line closes reopens for that shape: a round that read bbb, approved with no inline comments after a push to ccc, and now hands ccc back as the base — so bbb...ccc is reviewed by no cycle. A clean approve with no comments is the common outcome per the cycle 3+ Decision Framework, so single-review rounds are not rare; only the straddle on top of one is.

Your own fallback direction closes it cheaply: treat a last-finished round of length 1 as untrustworthy and step back to the previous round's window, or return "" and take the full diff. Worth a fixture either way, and worth softening lines 83–85 so the invariant reads as conditional rather than unconditional.

nit: PATCH_JQ is the one jq program here without test coverage (not blocking).

CYCLE_JQ, DRIFT_JQ and now LAST_SHA_JQ are all extracted from this file by extract_jq and asserted against fixtures — deliberately, per the comment on line 70. PATCH_JQ breaks that pattern, so the .files[]? guard and the .patch // "[no textual patch available]" fallback for binary/omitted patches are untested. It's the piece that decides what the model actually reviews on cycle 2+; a captured compare-API response as a fixture would put it on the same footing as the rest.

Fixed. PATCH_JQ now has fixture coverage on the same footing as the rest, via tests/fixtures/compare-incremental.json (a modified file with a patch, a binary file the API returns with no patch, and a removed file).

Note for anyone extending extract_jq: it could not be reused here. PATCH_JQ contains a literal \\n, and BSD sed expands that when writing a backreference, so the extracted program would carry a real newline instead of the two characters the workflow ships. It is pulled with awk instead, and there is an assertion on the output line count that fails if that escape ever degrades.

# hitting the cap exactly is the only truncation signal available without paginating.

nit: LAST_SHA == HEAD_SHA falls through to the full-diff message, not to "nothing new" (not blocking).

The trigger list includes ready_for_review and reopened (lines 4–5), neither of which changes the head SHA. So converting a reviewed PR to draft and back, or closing and reopening it, runs at cycle N+1 with LAST_SHA == HEAD_SHA, the if is skipped, and INCREMENTAL keeps its default — "Incremental diff unavailable - review the full diff with gh pr diff." The cycle 2+ prompt honours that literally ("Fall back to gh pr diff only if that block reports the incremental diff is unavailable"), so the model re-reads the entire PR on a tree it already reviewed. That is the full-diff re-review this change exists to stop, arriving through the one path where the incremental diff is genuinely empty rather than unavailable.

The two cases want opposite messages: unavailable → read everything; empty → there is nothing new, approve. Splitting the equal-SHA case out (INCREMENTAL='No changes have been pushed since your last review.') costs one branch and removes the only path that still re-exposes old code at a late cycle.

nit: the render-failure fallback ships a prompt that contradicts itself (not blocking).

cat-ing the unrendered file sends the model every cycle block at once, which means both ## Decision Framework sections — the cycle≤2 one ("Only nits/super nits → approve") and the cycle≥3 one ("No blocking issues → approve. No inline comments.") — plus prompt line 12 asserting "This prompt has already been narrowed to the current review cycle by the workflow", which is false on this path. tests/render-prompt-test.sh guards "exactly one Decision Framework" precisely because two leaves the model choosing between contradictory approve rules; the fallback is the one path that violates the invariant.

Reachable cases are narrow (script missing from the sparse checkout, malformed markers in a prompt edit) but they're exactly the cases where a warning gets buried in the log. Failing the step instead would route to the existing Notify on review failure step, which is a clearer signal than a review conducted under conflicting instructions.

Agreed, fixed. The context step now exits 1 rather than falling back to the unrendered prompt.

One thing your suggestion depends on that was not true yet: a failed context step skips the review step, so steps.review.outcome is skipped and the existing notify condition would not have matched — failing closed would have produced silence. The notify step now carries always() and also checks steps.context.outcome == 'failure'. Verified both trigger paths (missing script, malformed marker) exit 1 with an ::error::.

nit: always() makes the cancelled branch live, so every push that lands mid-review now comments (not blocking).

Before this PR the condition had no status check function, so success() was applied automatically and the step was skipped whenever the job was cancelled — which made steps.review.outcome == 'cancelled' unreachable. always() returns true on cancellation too, so that branch now fires.

With cancel-in-progress: true (line 9) that is the common case, not an edge one: a push while the model is reviewing cancels the run, steps.review.outcome becomes cancelled, and the PR gets "Automated review unavailable (Claude step failed). Please review manually." even though the superseding run is already computing a real review. This repo's own data says pushes land mid-review often enough to have shaped LAST_SHA_JQ.

Dropping the branch gets the new behaviour you want without the noise:

Suggested change
&& (steps.review.outcome == 'failure' || steps.review.outcome == 'cancelled'
&& (steps.review.outcome == 'failure' || steps.context.outcome == 'failure')

That keeps the context-failure path this PR added, keeps genuine review failures, and returns cancellation to being silent — same as before, so nothing regresses. (!cancelled() would also work but suppresses the timeout-minutes: 15 case, which also surfaces as cancellation and is worth notifying about; dropping the branch and leaving always() treats the timeout the same way the old code did.)

nit: still open from the last round — always() makes the cancelled branch live (not blocking).

Before this PR the condition had no status function, so success() was implied and the step was skipped whenever the job was cancelled, which made steps.review.outcome == 'cancelled' dead code. always() returns true on cancellation, so that branch now fires: with cancel-in-progress: true (line 9), every push that lands while the model is reviewing cancels the run and posts "Automated review unavailable (Claude step failed). Please review manually." even though the superseding run is already computing a real review. reviews-straddled-round.json and reviews-cancelled-round.json are this repo's own evidence that mid-review pushes are routine.

Dropping the branch keeps everything this PR added and returns cancellation to being silent, as it was before:

Suggested change
&& (steps.review.outcome == 'failure' || steps.review.outcome == 'cancelled'
&& (steps.review.outcome == 'failure' || steps.context.outcome == 'failure')

(timeout-minutes: 15 also surfaces as cancellation, so this does lose the timeout notification — but that was already the pre-PR behaviour, so nothing regresses.)

Automated code review on every pull request using [claude-code-action](https://github.com/anthropics/claude-code-action). Reviews are severity-based:

- **P0/P1 issues** — requests changes with inline comments
- **P2/P3 issues** — approves with non-blocking suggestions
- **Blocking issues** — requests changes with inline comments plus a summary comment
- **Nits / super nits** — approves with non-blocking inline comments
- **No issues** — silent approve

The review prompt lives in [`docs/claude-pr-review-prompt.md`](docs/claude-pr-review-prompt.md).

#### Review cycles

Re-reviews narrow as a PR iterates, so a long-running PR converges instead of accumulating new suggestions every round. The workflow counts prior review rounds and enforces the narrowing itself — [`scripts/render-prompt.sh`](scripts/render-prompt.sh) strips the sections a cycle does not qualify for before the prompt is sent, rather than asking the model to restrain itself.

| Cycle | Scope | Reports | Model |
| --- | --- | --- | --- |
| 1 | full diff | blocking + nits + docs | `claude-opus-5[1m]` |
| 2 | changes since last review | blocking + nits | `claude-opus-5[1m]` |
| 3+ | changes since last review | blocking only | `claude-sonnet-5` |

The model is pinned per cycle. Leaving it unpinned is what silently moved these reviews from `claude-opus-4-8[1m]` to `claude-opus-5[1m]`, which tripled cost per PR — change the pins deliberately, in a commit.

2. **Read prior review threads** — if cycle 2+, read the prior review comments included above to understand what feedback was already given and how the author responded
3. **Inspect the diff** — use `gh pr diff` to see what changed

5. **Post feedback** — use inline comments for specific issues, and a summary comment only when requesting changes

## Handling Prior Feedback

- **Blocking issues stay blocking.** If a prior review flagged a blocking issue, it remains blocking until it is fixed in the code. An author reply alone does not resolve a blocking issue — the code must change. If the author's reply reveals that your original assessment was wrong (e.g., you misread the code), you may drop it.

An author reply alone does not resolve a blocking issue — the code must change. If the author's reply reveals that your original assessment was wrong (e.g. you misread the code), you may drop it.
- **Do not re-raise resolved issues.** If prior blocking feedback was addressed in new commits, move on.
- **Do not re-raise nits the author declined.** If the author pushed back on a non-blocking suggestion with a reasonable explanation, respect their judgment and do not repeat it.
- If all prior blocking issues are resolved, update your review status accordingly (approve or request changes based on new findings only).

## Review Cycle Awareness

- **Cycle 1–2**: Full review. Flag blocking issues and nits.
- **Cycle 3–4**: Focus on blocking issues. Only leave nits if they are genuinely important.
- **Cycle 5+**: Blocking issues only. Do not leave any nits.

The goal is to converge toward merge, not to find new things to complain about in each round.
- **Do not charge the author for churn you caused.** Code comments and docstrings that drifted out of date because the author was addressing your earlier feedback are not new findings. Leave them alone.
- If all prior blocking issues are resolved, update your review status based on new findings only.

Report **blocking issues only**: security vulnerabilities, data loss, broken builds, correctness bugs, logic errors, missing error handling on critical paths, race conditions.

- **Do not nitpick.** Skip style issues that a linter should catch.
<!-- cycle<=2 -->
