Self-review — this is not an approval and must not be counted as one. These notes were produced by an automated review pass running under
s-annam's own token, on a PRs-annamauthored. GitHub correctly refused to register it as an approval (422, "Can not approve your own pull request"), and an earlier version of this comment restated the verdict as "APPROVE" anyway — that was wrong, and this body has been corrected. PR #842 still requires review by a second person before merge.
Findings summary — read as review notes, not as a sign-off. Five issues, 2,286 lines, one commit, and this pass found no correctness defect. npm run verify runs green end-to-end on the head SHA here (359 files / 5,853 tests, build, check:fixtures, check:baselines, check:core), the two new fixture personas are synthetic, and every claim in the description round-trips to the code. Two Secondary findings follow, both about what Resolves #492 closes rather than about the code, plus answers to the four ## Review focus questions.
No Blocking findings were identified. That is an input to a second-party reviewer's judgement, not a substitute for it.
Blocking
None.
Secondary
S1 — Resolves #492 overrides the fork decision recorded on that issue, without citing it.
The only comment on #492 (2026-07-15, 32 min after filing) reframes the issue away from this PR's approach:
"Net: I'd lean Fork B. That reframes this issue — gap 1 (the parser dropping the section) stops being a bug to fix and becomes intended floor behavior."
Fork B's argument is a product-honesty one, not an implementation preference: a headerless work history is a genuine cross-parser portability risk, so teaching our reader to recover it hands the candidate a reassuring score for a résumé a simpler downstream parser will still mangle. This PR is Fork A — recoverHeaderlessExperience (sections.ts:1060) does exactly the "detect a headerless dated-role cluster and open experience at the first" that Fork A describes — and auto-closes the issue without mentioning the comment.
I am not calling this Blocking: the comment says "I'd lean", the issue body's acceptance criteria were never rewritten and still describe Fork A, and the code delivers those ACs. But the merge closes #492 and the fork question goes with it. Either post a **Clarification** — note on #492 recording that Fork A won and why, or add a paragraph to the PR body. Right now the record reads as if the last decision was reversed silently.
S2 — #492's AC 5 is superseded rather than met, and the residue it covers is uncaptured.
AC 5: "/probe-experience reports a defect (not 'ok') on a headerless-experience résumé." Nothing in the diff touches the probe lane — src/lib/heuristics/localize/experience.ts is byte-identical to main and there is no experience-no-section defect class (ExperienceDefectClass still has only experience-parser-miss / experience-under-segmented). localizeExperience still scopes its date-range oracle to the already-routed experience region (localize/experience.ts:92), which is the exact blind spot #492 gap 2 describes.
For the single-column case that is now correct: the fixture routes an experience section, so "ok" is the right verdict and the AC dissolves. But recoverHeaderlessExperience returns early on !singleColumn (sections.ts:1064), so a two-column headerless work history is still dropped whole — and for that résumé the probe still says Verify: ok with zero roles parsed, invisibly, exactly as before. Resolves #492 closes the issue with that gap unrecorded.
The ## Open, non-blocking list is unusually complete — it names the connector particles, the ordinal digit-strip, the INSTITUTION_HINTS recall loss, the sidebar stat-badge FP, the roleFromSection duplication, even the fallow count — which is what makes this one omission stand out. Suggest: file a follow-up for the experience-no-section defect class covering the two-column residue, and add it to that list.
Review focus — answers
1. HEADER_CONNECTOR_WORDS and non-English particles (de, van, von, del, la). Worth adding, and cheap. The list is a reject list, so every addition is strictly one-directional — it can only make looksLikeVerbLedScope more conservative, and the failure it prevents (a preempted employer line loses company and the , City, ST that rides with it) is the expensive direction, as blocking finding #1 in your own review pass demonstrated. "Unified Communications de Mexico" is contrived, but "Banco de Mexico", "Van Der Berg Systems" and "Grupo Modelo de Mexico" are not, and each needs only its lead word to be in ACTION_VERBS to trip. Not a blocker — the guard needs both a lexicon verb lead and the particle — but it is the same class as the bug you already fixed, so it belongs in the same list rather than deferred indefinitely.
2. Does atSplit.length === 2 hold for Title, X · Team where the trailing cell isn't a location? Yes, and the reason is stronger than the gate itself. splitRoleComma runs on segment 0 only, of a two-segment line, and yields at most two parts — so the re-split can produce at most three via: "delim" splits, never more. Three delim segments is already a supported, tested shape: experience.role-comma.test.ts's own three-segment negative ("Sr. Engineering Manager · Site Lead, Payments Platform · Globex, Toronto") asserts the mapper reads title-first across three cells. So "Data Analyst, Retail · Northwind Co." becomes ["Data Analyst", "Retail", "Northwind Co."] and lands on the same path as "Data Analyst · Retail · Northwind Co." would have — which is the right answer, not an accident. Keeping via: "delim" (rather than "comma") is what makes that true, and the comment at experience-disambiguate.ts:628-634 states the reason correctly.
3. Should a month-dated cluster misrouted into the other sink be recoverable as employment at all? On balance yes, because the precondition is stronger than the host list suggests: the recovery only runs when the document routed no experience section anywhere. A résumé that has a real experience section and a BOARD SERVICE block in other is untouched. The exposure is the narrow intersection — no recognized experience heading, and an unrecognized heading opening other over ≥2 strongly-dated title-cased entries — and in that document the alternative is not "correct routing", it is "the entries stay in a sink nothing extracts". If you want to tighten it later without narrowing the recovery, the lever is the host's rawHeading: profile and summary have none or a benign one, while an other opened by a keyword-matched heading (as HIGHLIGHTS is here) carries the label that says what the block actually is. Not needed now.
4. Is fail-closed right for the un-anchored INSTITUTION_HINTS guard? Yes for the direction, and the docblock's own reasoning holds — a degree list read as employment is worse than a school-employed role left in place. The part worth pulling out of the docblock and into an issue is the cluster-level consequence it states but does not size: because the guard is per-line and the cluster needs HEADERLESS_ROLE_CLUSTER_MIN survivors, an academic or edu-sector résumé where every role is at a University/College/Institute never reaches 2 and recovers zero roles — the recovery is systematically inert for a résumé population that overlaps heavily with the headerless-CV convention it was built for. Not a regression (those résumés were dropped before too), so nothing to change here. But the docblock already names the symmetric fix — anchor the institution half to the lead, since a real education entry leads with its degree, not its school — and that is a follow-up issue, not a comment, given #492 closes on this merge.
Nits
Two, both left inline where they live: the lineLooksLikeDatedEntry hoist in classifyLine, and the confidence number in the top-skills snapshot.

Two things worth saying out loud, because they are why this reads as a five-issue PR that is easier to review than most one-issue PRs: the ## Adversarial review section reports three of its own blocking findings with the measurement that produced each, including one where #708's stated justification is called false and re-measured — and the negative tests carry the argument. sections.test.ts cases (d)–(g) pin both sidebar polarities and the peer-column and dated-entry rejections; line-primitives.below-anchor-prose.test.ts pins "Planned Parenthood of Greater Ohio" and "Secured Lending of the Midwest" as the shapes that kill the two rejected variants of the fix. That is the part that makes the columnBand and verb-lead widenings safe to merge, not the docblocks.
No commit pushed from this review: nothing non-behavioural was left worth fixing. S1 and S2 both need your judgement (an issue-closure decision and a follow-up), N1 is a code restructure in the parser's per-line path, and N2 is a line of PR prose. The DATE_RANGE_RE.lastIndex = 0 resets in looksLikeHeaderlessRoleHeader and splitAnchorProseTail are dead on a non-global regex — I checked before flagging them and they match the established pattern at entry-blocks.ts:308/722/1388, so they are house style, not a finding.

Revision round — all four review items closed. Branch force-pushed to
On S1, the fork question is answered in the PR body rather than on #492 so it travels with the code that decides it. Short version: Fork A wins on scope, not by disagreeing with Fork B's premise — the recovery fires only when the document routed no experience section anywhere, so it cannot mask a portability risk in a résumé that has a real header, and a parser that silently drops the largest section of the document cannot tell the user anything true about it, including that it is at risk. Fork B's obligation is a messaging one and it survives intact; #848 is where it lands. Gates on Still blocked on a second-party review. The earlier review comment on this PR is a self-review — it ran under the author's own token, GitHub refused to register it as an approval, and it carries none. |

The merge queue derives `main`'s squash message from repo settings (`squash_merge_commit_message: COMMIT_MESSAGES`) and its enqueue API carries no message fields, so only a single-commit PR merges with a written message instead of bulleted commit soup. That invariant was maintained by three hand-rolled copies which had already diverged, and `pr-review` broke it outright — it pushed an auto-fix commit and forbade the force-push needed to restore one commit. Add `.claude/skills/collapse-pr/` as the single owner of the mechanics and the rationale; `open-pr`, `revise-pr` and `pr-review` now each keep only their own decision about *whether* to collapse. Correctness properties the skill enforces: - resolve an existing PR's head from `origin` and rewrite it in a throwaway worktree; the local checkout is never assumed to be the target. A dry run against PR #842 found the checkout holding a superseded copy of a commit, one fewer than origin — collapsing from it would have destroyed a fix that existed only on origin - `--in-place` lets a caller that owns the checkout say so, rather than inferring mode from whether a PR happens to exist; that inference silently discarded local work when `open-pr` was re-run - assert the collapsed tree is byte-identical to the pre-collapse head. That assertion, and only that assertion, licenses skipping the managed `pre-push` hook — and only in a throwaway worktree, never in place, where the hook is the sole local verification - five gates: stale approval and open threads are soft (`--yes` proceeds); branch ownership and the push lease are hard - gate 3e resolves a diverged checkout losslessly instead of asking a human. Whether local work is unique or merely superseded is not mechanically decidable — `git cherry` and reverse-apply both report "unique" for an amended copy — so commits are preserved at a `collapse-pr-backup/<branch>-<utc>` ref before any reset, and the backup is a hard precondition of it `pr-review` now collapses between its auto-fix push and its review post, which is the only ordering that works: the collapse rewrites every SHA, so inline anchors must be derived after it, and `dismiss_stale_reviews` means collapsing after the approval would dismiss it. It preserves the author's commit message via `--message-file` rather than substituting one the reviewer wrote, and emits suggestion blocks where it cannot push. Closes #849
Five parser-lane cases from epic #811 where section routing dropped or mis-assigned content instead of failing visibly: an unrecognized `Top Skills` heading, a sidebar-left two-column layout whose anchor-ending company name swallowed the document, a below-anchor scope line that filled `team`, a headerless experience section that dropped the entire work history, and role titles collapsing into `company` on comma-delimited headers. Net corpus effect: 5 of 60 fixtures improve, none regress. - route unrecognized skills headings and recover the section (sections.ts, sections.config.json, regex.ts) - stop an anchor-ending company name from consuming the document in sidebar-left two-column layouts (line-primitives.ts) - keep a below-anchor scope line out of `team` (line-primitives.ts) - recover a headerless work history when no experience section routed anywhere (recoverHeaderlessExperience, sections.ts) - split role titles from `company` on comma-delimited headers (experience-disambiguate.ts, experience.ts) - normalize path separators in the extract-cache fingerprint test so it passes on Windows `top-skills-header-unrecognized` records cascade confidence 0.91 -> 0.87 while overall rises 91 -> 94 and skillsCount 0 -> 3. Cascade confidence is a weighted mean over non-zero fields (confidence.ts:95), so recovering a section adds a term rather than raising one: `skills` enters at weight 1 (thresholds.ts:124) below the mean of the fields already present. Strictly more of the résumé is parsed and the blend still falls; the ATS score, which counts completeness rather than averaging it, moves up. #492 is implemented as Fork A. The recovery fires only when the document routed no experience section at all, so it changes the floor case from "the work history does not exist" to "the work history exists and is scored" rather than masking a portability risk in a résumé that has a real header. Fork B's messaging obligation survives intact and is tracked in #848. Closes #575 Closes #574 Closes #708 Closes #492 Closes #543

…hing local work (#852) Round-4 review of #851 found three blocking defects, all in gate 3e row 1 — the ~230 lines added in round 3 that no prior review had seen. All three share one root cause: a precondition stated in the row table as prose while the executable blocks carried no condition at all. - row 1 is now opt-in in code. `ROW1=run|skip` gates the commit, ancestry and publish blocks. Previously the rows ran for every matched worktree, so a checkout that was clean but held a local-only commit fell through the dirty check, `git commit` failed and was silently discarded, and the user's unreviewed commit was cherry-picked and pushed into the PR. That reproduced on the skill's own #842 worked example. - the cherry-pick branch no longer pushes. It pushed from the throwaway worktree, which shares .git/hooks and has no node_modules, so the pre-push hook failed on every run — and Step 0b's bypass licence does not cover it, because cherry-picked content is new relative to origin. The fix now stays in $WORKDIR and Step 5's collapse publishes it under the lease already pinned in gate 3d. The re-pin block is scoped to the push branch, which would otherwise reset --hard away the cherry-pick. - the cherry-pick branch's backup ref is real code, not a placeholder comment. It was the only thing between row 3's reset --hard and unrecoverable loss, and the prose then told row 3 not to mint one. Row 3 short-circuits on $BACKUP. Also fixed, same class — a status check whose result was discarded: - Step 5 and row 1 capture the push status with `|| PUSH_FAILED=1` and chain the rollback. There is no `set -e`, so an unchained failure was discarded and Step 6 would report a collapse that never landed. Documents why the push must not be piped through `tail`: `$?` then belongs to the filter, and `$PIPESTATUS` is bash-only — under zsh it expands empty and fires the rollback on a push that succeeded. - the cherry-pick is chained; an unchained conflict fell through to a push of $WORKDIR's unchanged head, dropping the fix while reporting success. - row 2's refusal runs the teardown in code instead of a comment saying it should. - PR discovery distinguishes "no PR exists" from "the call failed". An empty PR_NUM selects in-place mode, so an auth expiry or rate limit silently redirected the rewrite at the user's own checkout. - row 1 skips on a clean authored worktree — the documented happy path, which previously reached `git commit` on a clean tree and failed. pr-review: - the pre-existing-dirty subtraction parses porcelain records properly. `cut -c4-` mangles a rename's bare second field, so it *under*-subtracted and left the user's in-progress rename whitelisted — the opposite of the safety direction the surrounding prose claimed. - the partial-failure rationale now matches what the code does, and names the inherited-state case it does not cover. Nits: temp-file cleanup in Step 5b, a distinct exit 2 for the no-net-change no-op so pr-review stops reading it as a refused gate, a TOCTOU-aware message on backup-ref collision, and the -z quoting claim dropped from the cut -c4- rationale. Verified by collapsing PR #842 for real: 3aeae1b + 72358ab -> c5eeec8, tree 56a742c identical on both sides, zero diff, lease pinned to 72358ab and accepted. Refs #849 Refs #851

Summary
Five parser-lane fixes from epic #811, accumulated on one branch as a single
commit. Each addresses a case where the parser silently dropped or mis-assigned
résumé content: an unrecognized
Top Skillsheading (#575), a sidebar-lefttwo-column layout whose anchor-ending company name swallowed the document
(#574), a below-anchor scope line that filled
team(#708), a headerlessexperience section that dropped the entire work history (#492), and role titles
collapsing into
companyon comma-delimited headers (#543).Net corpus effect: 5 of 60 fixtures improve, none regress.
One snapshot number moves down and is not a regression:
top-skills-header-unrecognized.expected.jsonrecords cascadeconfidence0.91 → 0.87 while
overallrises 91 → 94 andskillsCount0 → 3. Cascadeconfidence is a weighted mean over fields whose score is non-zero — a
missing field is excluded from the mean rather than scored zero
(
confidence.ts:95). So recovering a section adds a term:skillsenters atweight 1 (
thresholds.ts:124) carrying its own field confidence, which sitsbelow the mean of the fields that were already present, and the blend falls
even though strictly more of the résumé was parsed. The ATS score, which counts
completeness rather than averaging it, moves the other way — as it should.
On #492: this PR is Fork A
#492's one comment leans toward Fork B — treat a dropped headerless work
history as intended floor behaviour, on the argument that recovering it in
our reader hands the candidate a reassuring score for a résumé a simpler
downstream parser will still mangle. This PR implements Fork A
(
recoverHeaderlessExperience,sections.ts) and closes the issue, so thecall is recorded here rather than left to the merge.
Fork A wins on scope, not on disagreement with Fork B's premise. The recovery
fires only when the document routed no experience section anywhere, so it
does not paper over a portability risk in a résumé that has a real header; it
changes the floor case from "the work history does not exist" to "the work
history exists and is scored". A parser that silently drops the largest section
of the document cannot tell the user anything true about it — including that
it is at risk. Fork B's concern is a messaging obligation, and it survives
this PR intact: #848 covers making the two-column residue visible, and the
issue body's acceptance criteria (never rewritten toward Fork B) are what this
diff delivers.
