Pull request overview
Updates the deep-review GitHub Actions workflow to support a “VERIFY” relabel mode that reviews only the delta since the most recent marker review, instead of re-reviewing the entire PR, while allowing maintainers to force a fresh review via a deep-review: fresh steer.
Changes:
- Capture the newest marker review’s
commit_idaslast_shaand use it to drive VERIFY-vs-FRESH behavior on relabels. - Add a
freshsteer flag extracted fromdeep-review:comments to opt out of VERIFY mode. - Include
HEAD SHA,MODE, andLAST REVIEWED SHAin the prompt, and lower--max-turnsin VERIFY mode.

- The JSON compare response is not a complete delta: GitHub caps its
filesarray at 300 entries and can omitpatchfor oversized or binary files. Because the prompt says to review onlyfiles[].patch, executable changes outside that representation are silently skipped. Fetch the raw diff media type or allow a pinned localgit diff, and define how missing patches are handled.

`gh api repos/${{ github.repository }}/compare/<LAST REVIEWED SHA>...<HEAD SHA>`
(the `files[].patch` entries). Raise a new finding only for an
.github/workflows/claude-review.yml:421
- VERIFY conflicts with every ordinary persistent focus steer: the emitted block at line 335 says to “still review the entire diff,” while the new VERIFY instructions say to review only the delta. A relabel with a non-
freshsteer therefore gives the model contradictory scope and can trigger the full re-review this mode is intended to avoid. Make the focus wording mode-neutral (for example, the mode’s permitted review scope) or emit a mode-specific block.

awkexits after its first input line even when that line is blank, andsed '1s'only edits that same line. Thus a valid multiline steer such asdeep-review:\nfresh authdoes not select FRESH even thoughfreshis the comment’s first word. Match and removefreshafter all leading whitespace, including newlines.
if [ "$(printf '%s' "$TEXT" | awk '{print tolower($1); exit}')" = "fresh" ]; then

HEAD SHAis pinned to the label event, but the checkout still uses the mutable branch ref at line 344 and step 8 posts the review without an explicitcommit_idat lines 598-599. If a push lands after the event, VERIFY can compare only through commit A while the resulting marker defaults to the newer commit B; the next relabel then starts at B and never reviews A→B. Pin the checkout and submitted review to the same SHA used here solast_shaalways identifies the snapshot actually reviewed.
HEAD SHA: ${{ github.event.pull_request.head.sha }}
MODE: ${{ steps.dedupe.outputs.last_sha != '' && steps.focus.outputs.fresh != 'true' && 'VERIFY' || 'FRESH' }}

Re-applying the deep-review label ran a fresh, memoryless full review each time, so a PR relabeled after every fix push was re-reviewed from scratch and the reviewer could reverse its own earlier suggestion. On #643 that happened six times across 13 rounds. When a marker review already exists, a relabel now runs in VERIFY mode: the reviewer re-examines its own open threads (verified fixed, still wrong, or concede versus one rebuttal) and reviews only the compare range from the last reviewed commit to the head, raising new findings only for executable changes there. It posts the marker summary so the next relabel diffs from this head, and it runs under a smaller turn budget. A steer comment whose first word is fresh opts back into a full review. The last reviewed commit comes from the reviews API commit_id the dedupe step already fetched; the delta is read through the compare endpoint since the session has gh api but no git.
…ial compare The summary review is posted with commit_id set to the head SHA the run started for, so a push that races the session cannot advance the verify boundary past unreviewed code. The compare endpoint caps its file list and omits very large patches, so verify mode reads any file the response cannot show in full from the checkout instead of trusting the list.

- This new object/ancestry/merge decision is non-trivial workflow logic whose output selects VERIFY versus FRESH, but it has no automated coverage.
.github/CLAUDE.md:283-300requires such workflow parsing to live inscripts/*.mjswith anode --testsibling, specifically directing edited inline sentinel logic to be extracted rather than grown. Extract this boundary calculation and cover missing commits, diverged history, linear history, and merges so a shell regression cannot silently narrow the review.

…e-aware Checkout resolved the mutable head ref while the delta and the marker used the event's head SHA, so a push landing mid-run had the session review a newer tree than it recorded. It checks out the SHA now. The boundary also compares the merge base of the PR base with each end: a retarget exposes code neither commit introduced, and the two bases then differ, so the run falls back to a fresh review. An empty range does the same, since there is nothing for a delta to cover. The verify prompt reads the delta before it runs anything, because the commands it may run afterwards come from the branch.

- This new boundary state machine is non-trivial workflow logic but has no automated coverage. It controls whether review scope narrows and needs cases for retarget-plus-new-commit, missing/rewritten commits, merge ranges, unchanged heads, and valid linear deltas. Repository rule
.github/CLAUDE.md:283-300requires logic of this complexity to move toscripts/*.mjswith anode --testsibling.

- This does not actually detect every retarget. It only compares both commits against the current base, so a stacked PR retargeted from its feature base to
mainwhile also receiving a new commit can produce the same merge base forLAST_SHAandHEAD_SHA; VERIFY then reviews only the new commit and skips the older stacked commits newly exposed in the PR. The previous base identity must be recorded with the review marker and compared here (or the old/current PR diffs must be interdiffed); otherwise fall back to FRESH whenever that identity cannot be proven unchanged.

- This does not actually detect every retarget. It compares both heads only against the current base: if the PR was originally based on commit
Mand is retargeted to an ancestor or divergent branch atA, both merge bases can equalA, soSAME_BASE=yeseven though commits betweenAandMhave just become part of the PR diff. TheLAST_SHA..HEAD_SHApatch then omits that newly exposed code and the verify marker advances past it. Persist the reviewed base SHA/ref in the marker and require it to match before using VERIFY, or compute an interdiff of the old and current PR diffs.

- The claim that no PR-controlled script runs “in the job at all” is false: the Claude step below permits
pnpm run/test/execand explicitly asks the session to run tests. Only the pre-session portion has this property; narrowing the comment avoids overstating the job's security boundary.
# let the hook replace the file. With no PR-controlled script running
# in the job at all, neither holds: nothing between checkout and the
# session executes code from this branch.

… the deep review .github/CLAUDE.md was detailed about rules and silent about the threat model they serve, so a reviewer with no stated boundary invented one and kept narrowing it: on #647 a single step drew round after round of correct findings with every rule holding. A section before the invariants now states what the jobs are exposed to, names the accepted defences by rule number, and says where hardening stops: a step-to-step hand-off inside one job is not a trust boundary, and only a widening of who can trigger a job, what a credentialed job can reach, or what leaves the job is blocking. The deep-review prompt gains rule 4a, which restates that boundary and points at the section by heading, the way 6a carries the writing rules. Closes #654

Refs #643. Stacked on #646, which adds the prose rules this mode cites; the base retargets to
mainwhen that merges.What changed
One workflow,
claude-review.yml: two shell steps and one prompt block. No allowlist, permission, SHA, or job change.commit_idaslast_shabefore deciding. A relabel with a marker present logsverify since <sha>; with none it logsfresh. The non-label path is unchanged in effect.fresh=truewhen a steer comment's first word isfresh, and strips the word from the focus text. Steers persist across relabels, so deleting the comment returns to verify mode. No new label.HEAD SHA,MODE(VERIFY when a marker exists and nofreshsteer, else FRESH) andLAST REVIEWED SHA. All three are workflow-computed values.gh api …/compare/…since the session has nogit, raise new findings only for executable changes there, then post the marker summary with a(verify)heading so the next relabel diffs from this head.--max-turnsis 40 in VERIFY mode, 120 otherwise.Before and after, the trigger-facing part
Trigger impact: none. The workflow still fires on
openedandlabeledonly; who may fire it is unchanged; the one-review-per-PR invariant on theopenedpath is unchanged.What to check
pnpm format:check,pnpm check:conformance, andbash -non both edited steps pass locally.claude-review.yml, so the deep review skips it silently; CodeRabbit and Copilot are the reviewers.Verification of the mode itself needs a fixture PR opened from a branch carrying this file after merge; the steps are in the plan and I will run them then.
