Why

#35 made an incomplete review keep its progress, but on pixtuoid/pixtuoid#2213 the backlog never shrank. The unread counts by run were 27, 21, 22, then 31 and 29 after folds, so the check never cleared.

• The reading rule didn't say whose hunks. It said "each item its hunks touch", and Wiring said "a hunk changes", so the reviewers re-derived both from the whole diff, which ci(claude-review): an incomplete review keeps its progress, and the next one reads only what it left unread #35 made context. At 1d34dddcf, with no push between, a rerun listed 22 unread paths, 11 of them new.
• The model wrote the work list. Bounding the list by scope alone would converge, but it would drop coverage silently. Those 11 new paths show the anchoring run's own list under-enumerated by about half.

What

The workflow lists the work, and a review can only report what it judged.

• A unit is one hunk of the PR's three-dot diff.
  • Its id is a hash of the path and the hunk with its -U3 context. A push, or a main merge, that leaves the hunk and its surroundings alone keeps the id. An edit next to it changes the id, so the hunk is re-read.
  • Identical hunks are one unit, whose id ends in the number of them (.n). Adding or removing a twin changes the id, so the whole group is re-read.
  • A mode, rename or copy change is hashed into the file's first hunk, so a chmod on a file the PR edits re-reads it.
  • A file with no hunk (binary, or a pure mode change or rename) is one unit, <path>:file, keyed on its header.
• The Read: list. An incomplete review ends with a Read: list of the units both reviewers judged whole. A unit counts as judged once its hunks, the items they touch, read whole, and those items' Wiring reach have been read.
• The scope is replayed. The diff step goes through every verdict on a commit still in the PR, oldest first:
  • Each review's scope is the units new or changed since the review before, plus those still pending.
  • A complete review clears the pending set.
  • An incomplete review leaves its scope, minus the ids it listed.
  • So a unit left off the list, a garbled line, or an id no review was given keeps the unit in scope. An incomplete verdict always anchors, since it can only keep work.
• The PR's title and body, and the whole diff as context, stay in every run. The whole diff is the same diff the units are cut from, written once, so a unit's range is a hunk the reviewers read.
• The PR's commits come from the checkout (git rev-list <head> ^origin/<base>). The REST list stops at 250 (github/rest-api-description, pulls/{pull_number}/commits: "Lists a maximum of 250 commits"), and past that, verdicts on later commits would be skipped.
• since goes. The replay is the only anchor. The prompt no longer names a newest judged commit, which a list-less incomplete review would have made untrue.
• The recheck window moves on every incomplete verdict too. after is the second-newest verdict's time, and every incomplete verdict now counts, so replies an incomplete run already saw aren't rechecked again.

Measured on #2213 at 00b91c6c0 against main:

Key	Hunks	Distinct	In twin groups
-U0 (path + changed lines)	494	468	45
-U3 (with context)	337	332	10, in 5 pairs

A twin in another item has different context, so it gets its own unit.

Tested

claude-review-test.sh runs the real scope and diff steps over git repos.

The scope:

• With no verdict, every unit is in scope, and the PR's own .gitattributes turns no hunk into a file unit.
• A unit the merge of main left alone keeps its id, so a complete review judged it.
• An incomplete review takes a unit out only when it lists that unit. A unit left off, or an invented id, keeps it in scope.
• Reruns at one head shrink the scope by what each one lists, and a verdict on a commit a force-push dropped is skipped.
• The handoff. The scope step's real verdicts.jsonl reaches the diff step unchanged, and the diff step takes the PR's commits from the checkout. An incomplete review that listed p1 takes it out, and one that listed nothing keeps it. That pins the incomplete flag, the record's keys and the file name.

Unit ids:

• A hunk that a push shifts, with its context intact, stays out. A new hunk at the top of the file comes in.
• Two twins form one .2 unit, and a third makes it .3. The same change in two different items is two units.
• A chmod re-keys the file. A path with b/ in it keeps its name. Git ends a ---/+++ path that contains a space with a tab (measured).

The Read: parse:

• It handles unit lines, a twin id, a whitespace-only line, a sub-bullet, an old-style item line and prose.
• A line the diff step wrote parses back to its id.
• The prompt's step-3 wording is pinned to that format.

These mutants each turn the script red:

• the pending set ignoring the list;
• no mode key;
• -U0 keys;
• no twin count;
• no --attr-source;
• no tab strip;
• a 16-hex id;
• incomplete: false;
• a renamed verdicts file;
• no whole diff from the unit lister.

Every command ci.yml runs exits 0 locally.

Failure modes

• A same-count swap. In one push, one twin is removed and an identical twin is added elsewhere, with an identical change and identical ±3 lines of context. It keeps the group's id. That needs the change and its 7-line window to be identical, and the count to be unchanged.
• Re-reads after nearby edits. A fold that edits near a hunk re-reads it. That fails toward reading.
• A review that lists a unit it didn't judge. That unit drops out. The list is the reviewers' own claim, the same trust every verdict already rests on.
• A unit too big for one run. A unit too large to judge in one run stays in scope across runs. There is no chunking: a size limit would be a magic number with no measurement behind it. If this happens, that run is the measurement.
• A run killed by the 30-minute timeout posts no verdict, so it keeps no progress, as before.
• Verdicts from before this change. An incomplete one carries no Read: list, so its whole scope stays pending. A complete one clears its units, as before.

Walkthrough

The workflow replaces commit-anchor and unread-item scoping with stable diff-unit IDs. It replays eligible verdicts, writes the whole PR diff and remaining units, and updates reviewer prompts and tests to use Read: lists of judged units.

Changes: Verdict-based diff-unit review scope

Layer / File(s)	Summary
Verdict parsing and scope replay .github/workflows/claude-review.yml, .github/scripts/claude-review-test.sh	The workflow extracts valid unit IDs from incomplete verdicts and replays verdicts for commits still in the PR. Complete verdicts clear prior scope; incomplete verdicts leave unlisted units pending. Tests cover verdict parsing and review-context setup.
Diff-unit generation and filtering .github/workflows/claude-review.yml, .github/scripts/claude-review-test.sh	The diff step derives unit IDs from hunk paths and context, groups identical hunks, and represents files without hunks. It writes the whole head diff and remaining unit list. Tests cover filtering, reruns, force-pushed commits, and unit identity cases.
Review contract and test coverage .github/workflows/claude-review.yml, .github/scripts/claude-review-test.sh	The prompts define scope using units and touched items. Incomplete reviews report judged units in Read: lines. Tests check the required format.

Estimated code review effort: 3 (Moderate) | ~30 minutes

Merge Risk: Low · up to efffe

The review workflow rebuilds its scope from the GitHub commit API, which stops at 250 commits. Only very large PRs are affected, and they would see repeated whole-diff reviews rather than wrong results. The change is mergeable, and computing the commit list from local git would be a small follow-up.

Nitpick comments: 1

.github/scripts/claude-review-test.sh: 1

313-314: Trivial · Maintainability & Code Quality · Low value

Remove the vacuous "twins split" assertion.

The grep -Eq '^- [0-9a-f]{12} w:\+1,6$' pattern cannot match any scope line that the fixture produces. The w fixture has four blank lines, then fn a() { on line 5 and x on line 6. With -U3, the first twin hunk is therefore +3,7. The second twin hunk starts later. No hunk is +1,6, so && fail never runs, whether or not the twins are split.

The next assertion (Line 316) already fails when the twins are split, because the id would then lack the .2 suffix. Delete these lines, or change the pattern to the real range, for example w:\+3,7.

♻️ Proposed fix

-grep -Eq '^- [0-9a-f]{12} w:\+1,6$' "$(scope_of one)" &&
-    fail "diff one: twins split into units"
 twins="$(id_of one w)"

Blocking: 0

Verdict: No blocking defects. The design works: the workflow builds each scope from its own unit list, so an id a review invents can't add work. Both reviewers judged that the mechanism earns its upkeep against #2213's backlog that never shrank.

Verifiers kept 11 non-blocking findings, all posted inline:

• The claim "a unit can't be dropped without being judged" doesn't hold (PR body and title). Under-listing Unread: still drops units silently.
• A test can't fail:
  • claude-review-test.sh:277 doesn't catch units() losing --attr-source.
  • claude-review-test.sh:313-314 can never match.
• Behavior:
  • A mode-only change to a file that has hunks never enters the scope (claude-review.yml:119-127).
  • A path containing b/, or a quoted path, gets the wrong unit path (:132).
• One source: the 12-hex id format in UNITS and VERDICTS crosses a boundary and no test pins the pair (:62).
• Words:
  • The run_diff and id_of comments are untrue (claude-review-test.sh:256-257, :271).
  • The scope output collides with step id scope (claude-review.yml:168).
  • The step name says "hunks" (:101).
  • "unread items" at claude-review-test.sh:98.
  • The prompt's unit definition omits <path>:file units (:201).

Verifiers dropped three candidates:

• the duplicated git diff invocation (no reachable divergence);
• OrderedDict versus dict (taste);
• the comment at claude-review.yml:40 (still true enough).

Changes the reviewers listed:

• VERDICTS: now accepts only - <id> … unit lines.
• Scope step: its unread output now feeds the diff step's UNREAD and no longer goes to the prompt.
• Diff step:
  • Renamed.
  • New UNITS Python, which hashes path and hunk with -U3 context and groups twins as .n.
  • New units() run at the head and at the anchor.
  • New awk join that writes scope.md.
  • The diff output is replaced by scope, and whole stays.
  • The git log -p per-commit scope is removed.
• Prompt: the reading-rule bullet, Wiring's "scope hunk", the scope sentence and step 3's Unread: format.
• Tests:
  • The incomplete-* parse cases are moved to unit lines, including the empty-list and old-format cases.
  • The diff-step tests are rewritten: whole, since, since-bogus, since-unread, shifted hunk and twins.
  • The prompt pin is updated.

Claims checked:

• Hold at the head:
  • The four mutants are each caught: by :317, by :316 and :326, by :293, and by :282.
  • "An id the model invents can't add work" holds (:288).
• Unverified:
  • The #2213 measurements, which are in another repository and were not fetched.
  • "Every command ci.yml runs exits 0 locally", which was not run.

AGENTS.md and REVIEW.md do not exist at the base commit, so there are no must-run items.

Pre-existing: claude-review.yml:155 writes whole.diff without --no-color, so a runner whose git config sets color.diff=always would put ANSI codes in it. The default runner doesn't reach this.
Pre-existing: the diff-step test pipes paths through locale-dependent sort and compares against .gitattributes a p1 p2 (files() at the base, paths() at :270). A GNU collation locale that ignores the leading dot would reorder them. This is unverified.

[github-actions]

Blocking: 0

Verdict: The inversion in 67483c7 is sound. A review now lists the units it judged under Read:. The diff step replays every verdict, and a unit stays in scope unless a review lists it, so units left off a list, garbled lines and invented ids are all kept. I'm posting 5 non-blocking findings inline:

• The UNITS comment says a unit leaves scope only once a review lists it, but a complete review also clears its scope (:109-111).
• since is now a second copy of the replay's anchor, and the prompt sentence that reads it is untrue after a list-less incomplete review (:212).
• The three-dot diff command is duplicated between Python and bash, and nothing pins the two together (:133-134).
• The body doesn't mention that incomplete verdicts now move the recheck window after (:58).
• No test fails if VERDICTS gets incomplete wrong, or if the scope→diff step handoff drifts (test :103).

Rechecks: I rechecked all 10 findings from the previous review that were replied to as FIXED, and the verifier dropped every one. Each fix holds at the head:

• Read-list inversion and title/body wording
• p1:+1,1 attr-source pin
• grep -c ' w:' twin check
• mode key in the first hunk, with the x.sh case
• path_of/unquote with the d b/c case
• run_diff/ids_of comments
• read-back id-format pin
• units output rename
• step name
• assert_since comment

Changes the reviewers listed:

• Removed: the unread output, the SINCE/UNREAD env, units.now/units.anchor/scope.md, and the awk join. No consumers remain.
• Renamed: the diff step's output scope → units (units.md), consumed by the prompt at :212.
• New file: $dir/commits, read by the since awk (:80) and by UNITS as in_pr.
• VERDICTS record: unread is replaced by incomplete + read. Both are consumed by the replay at :165. Only read is pinned by tests.
• VERDICTS selection: it now admits every Blocking: incomplete, which shifts since and after. The fail step reads only line 1 and is unaffected.
• Transition: old Unread: bodies never match the exact Read: line. They replay as incomplete with read = [], so their whole scope stays pending.
• Prompt: step 3's Read: wording matches VERDICTS and is pinned by the prompt test.

Pre-existing: the test runs system jq, while production's gh api --jq uses gh's embedded gojq. Any difference between them goes uncaught, including support for the (?<id>…) named group (unverified; gh source not fetched).
Pre-existing: since relies on the reviews endpoint returning reviews oldest first, and the replay now relies on the same order (unverified; API docs not fetched).
Pre-existing: the PR-commits API list may be capped (reported as 250 commits; unverified, docs not fetched). At the base, a judged commit past the cap already left since empty.

[github-actions]

Blocking: 0

Verdict: No blocking findings in ff5b8d4. Three non-blocking findings are posted inline:

• A run-block comment that still describes the diff command this commit moved into units() (claude-review.yml:171-175).
• handoff-incomplete passes even when no verdict is kept, and its fixtures copy commit() and review() (claude-review-test.sh:281-286).
• run_diff_in's comment says its directory is always the scope step's (claude-review-test.sh:219).

There is no AGENTS.md or REVIEW.md at the base, so the review contract was the only rule set and there were no must-run items.

Rechecks: I rechecked all 11 earlier findings the author marked fixed in 67483c7. Each fix is present at the head, and none was kept.

Changes the reviewers listed (ff5b8d4):

• Workflow, since: removes the since awk, its comment, the since= output and the prompt sentence that named the newest judged commit. The replay in UNITS is now the only anchor.
• Workflow, whole diff: UNITS takes a fifth argument, whole, and units() writes the head's raw diff there. The separate bash git diff is gone, so the units and the reviewers read one diff.
• Workflow, comment: rewrites the UNITS comment. A complete review takes its whole scope out, and an incomplete one takes out only the units it lists, on commits still in the PR.
• Test script, assertions: run_step now sets $dir. assert_since is replaced by assert_verdicts, which pins each kept verdict's commit, complete or incomplete flag, and read ids.
• Test script, cases: drops the force-pushed, rebased, incomplete-force-pushed and human cases (the dropped-commit skip is still covered by reruns) and folds a human review into no-verdict.
• Test script, helpers: splits run_diff into run_diff and run_diff_in, moving the output to $work/diff-$1.out.
• Test script, new cases: adds the end-to-end handoff and handoff-incomplete cases.

The correctness reviewer checked every claim in the PR body against the head and found it holds. "Every command ci.yml runs exits 0 locally" is unverified, because nothing was run.

Pre-existing: the recheck window after and the replay order depend on the pulls/$PR/reviews endpoint returning reviews oldest first, and no GitHub source is cited for that order (unverified).

[github-actions]

Blocking: 0

Verdict: c8c6dd4 is sound. It has no blocking findings and one non-blocking finding, posted inline: the size-cap clause in the comment moved onto units() (.github/workflows/claude-review.yml:132) cites no source.

Correction to that inline comment's suggestion block: the block repeats line 131's wording and should not be applied as written. Apply this fix instead:

• Line 131 ends "here pinned to a commit;".
• Line 132 becomes # it reads the base's .gitattributes, so.
• Alternatively, keep both lines and mark the size-cap clause "(unverified)".

Changes the reviewers judged (7, scope c8c6dd4):

1. claude-review-test.sh:52-53: sha() now passes a real 40-hex commit through, and has a new comment.
2. claude-review-test.sh:220-221: the run_diff_in comment now names both kinds of caller.
3. claude-review-test.sh:275-276: the handoff case uses commit() and review() in place of inline JSON.
4. claude-review-test.sh:281-282: the handoff-incomplete case does the same.
5. claude-review-test.sh:284-285: a new assertion checks that VERDICTS keeps the list-less incomplete verdict as <p1> true.
6. claude-review.yml:130-133: the three-dot-diff rationale and its docs citation moved onto units().
7. claude-review.yml:175-176: the run-block comment is shortened to say that UNITS writes the whole diff.

Rechecks: all 8 earlier findings marked FIXED were rechecked against the head (comments 4525887678, 4525888866, 4525889569, 4525890315, 4525891551, 4526020552, 4526022165, 4526022940). None was kept: each defect is gone at the head, or the PR body now states the change.

Rules: AGENTS.md and REVIEW.md do not exist at the base, so no repository rules or must-run items apply beyond the review contract.

[github-actions]

Blocking: 0

Verdict: I found nothing in this scope. The only commit after c8c6dd4 is efffe13, which changes comment text and no code. The base has no AGENTS.md or REVIEW.md, so only the review contract applies and there are no must-run items.

What changed in scope

• .github/workflows/claude-review.yml:130-133: the comment above units() loses the clause "and free of the API's size cap", and the remaining lines are rewrapped.
• What the comment still says holds at the head:
  • "pinned to a commit" is true: every caller passes a commit SHA to units(rev) (v["commit_id"] at :167, head at :170).
  • "reads the base's .gitattributes" is true: the command passes --attr-source=origin/{base} at :135.
• No other text in the repo mentions a size cap.

Rechecks. Each of the four earlier findings the author marked fixed was re-verified at the head, and none of them still holds:

• The run-block comment describing a diff that wasn't in the block (4526020552): the run block at :175-176 now describes what UNITS writes, and the three-dot reasoning sits above units().
• handoff-incomplete passing with no verdict kept (4526022165):
  • claude-review-test.sh:283-285 now asserts the list-less incomplete verdict is kept before it checks the scope.
  • sha() passes a 40-hex SHA through, and both handoff cases use commit() and review().
• The run_diff_in comment (4526022940): claude-review-test.sh:220-221 now names both directories its callers pass.
• The unsourced size-cap clause (4526123789): deleted in efffe13.

Pre-existing defects noticed: none.

Blocking: 0

Verdict: no blocking findings in d7198fc, the only commit after the last judged one (efffe13). The PR's commit list now comes from the full-history checkout, via git rev-list <head> ^origin/<base>, in one place. Nothing still reads or writes the removed $dir/commits file or the commits argument, and the test stub now refuses the pulls/{n}/commits path. The verifiers kept one non-blocking finding: the PR body's "Tested → The handoff" bullet still names a commits file the head no longer has. It is posted inline.

Neither AGENTS.md nor REVIEW.md exists at the base commit, so there were no repository rules and no must-run items to check.

Changes the reviewers listed (d7198fc):

• claude-review.yml:
  • The scope step drops its pulls/$PR/commits fetch and no longer writes $dir/commits (:75).
  • UNITS drops its commits argument (:111).
  • UNITS builds in_pr with git rev-list and a comment citing the 250-commit REST cap (:162-166).
  • The diff step's python3 call drops "$DIR/commits" (:181).
• claude-review-test.sh:
  • The stub's commits path is removed (:37-41).
  • commit() and every page commits fixture are removed.
  • new_case pages only reviews and comments.
  • run_diff no longer writes commits.
  • run_diff_in's comment is rewritten (:211-212).

Rechecks: dropped, because the head no longer has either defect.

• 4526123789: the "size cap" clause is gone from the units() comment.
• 4526233896: no pulls/{n}/commits call remains, and in_pr comes from local git on a fetch-depth: 0 checkout.

Unverified: this run did not fetch github/rest-api-description or actions/checkout. It could not confirm the 250-commit cap the new comment cites, or that the checkout creates origin/<base>.
