fix(review): make the posted review body readable - #8825
Conversation
The posted body on a capped COMMENT joined every clause with spaces: on #8388 that ran 31 unresolved existing Criticals and seven disclosures into one paragraph, each entry restating the same truncation reason, every comment id a bare number, and the Chinese fold duplicating the whole untranslated wall. - Render the COMMENT body as paragraphs: the short verdict sentences stay one opener paragraph, every disclosure gets its own (matching the REQUEST_CHANGES branch). - Render the unresolved-Critical block as a Markdown list, grouping entries that share the exact reason after their first " — " so the reason is stated once over a sub-list of subjects. Nothing is dropped: every subject and every distinct reason still renders. - Linkify "comment <id>" / "issue-level comment <id>" in those entries to their #discussion_r / #issuecomment anchors when the plan names the PR. - The Chinese fold no longer duplicates the untranslated English list; it carries the count and points at the English half. - budgetGapDisclosures: a parenthesized placeholder ("(none — all planned checks completed)") now reads as a placeholder — the leading "(" defeated the leading-token match, and #8388's body disclosed it as a self-contradictory "Not explored to full depth" entry.

- budget disclosures: the completion idiom now requires an actual
completion predicate the text ends with — a head word alone ("none —
all 5 Windows checks failed to start") no longer reads as done — and
the template/dash alternatives are end-anchored, so an inner text
merely starting with "<…>" or a dash run keeps. One strict classifier
judges the paren-stripped text, bare and wrapped alike, ending the
divergent two-parser treatment of identical content ("none of the
chunk-2 checks ran — the runner died" was kept wrapped, dropped bare).
- budget parse linearity: the placeholder classifier, the gap-line
regex, and the trailing-punctuation strips no longer carry
overlapping quantifiers — a token followed by a long whitespace run
was measured quadratic (seconds at 40k spaces); every shape is now
linear by construction and pinned by the linearity test.
- comment anchors: the effective host is normalized (case and the
implicit :443) before the github.com short-id floor comparison;
"issue-level" reads case-insensitively, matching the pipeline's own
capitalized label; a plan ownerRepo carrying "."/".." segments is
rejected before it rides into a posted URL.
- tests: the plan fixture carries the PR identity instead of four
pasted read/modify/write backdate dances; the anchor suite is
hermetic against an exported GH_HOST and now pins the host-fallback,
host-rejection, ownerRepo-rejection, routed-host, prefixed-cannot-
tell, and cased-Issue-level branches; the Chinese fold assertion
covers the pointer, not just the count.

Linearity ladder (commit 3's claim; witness 03-linearity-ladder-base-vs-head.png,
ladder.mjs, one process per rung, timeout 30): Budget gap: none<N spaces>x:
| N spaces | head | base |
|---|---|---|
| 2 000 | 0.54 ms | 4.23 ms |
| 3 000 | 0.56 ms | 8.91 ms |
| 5 000 | 0.58 ms | 26.06 ms |
| 20 000 | 0.88 ms | 399.57 ms |
| 40 000 | 1.13 ms | 1 550.85 ms |
Textbook quadratic on base (~4× per 2× rung), flat on head; 5 scripted head-rung
assertions (< 100 ms) all pass. Scaling note: this parse runs on every agent
return, but the input is the pipeline's own agent text, not outsider-authored —
robustness, not a ReDoS boundary.
Sibling sweep on head (sweep-head.mjs, 14/14, witness in logs/):
already-linked entry left byte-identical; dangling — reads as reasonless (no
entries — : empty key); multi-line entries collapse into one list item; GHE plan
host anchors short ids with no github.com floor; invalid plan host rejected and
falls back to github.com (host text never reaches the URL); GH_HOST=GitHub.com:443
normalizes so the 6-digit ordinal floor still holds (5-digit stays bare);
capitalized Issue-level anchors under #issuecomment; ownerRepo: "../evil"
rejected (no anchors, entry renders bare); no plan → bare verbatim entry.
Corrections
None needed. The description's claim that paragraphing "match[es] what the
REQUEST_CHANGES branch already did" was verified against base source: base had
render(parts, '\n\n') early-return branches for REQUEST_CHANGES and APPROVE, and
the wall was specifically the COMMENT fallback's render(clauses, ' ') — exactly the
call site this PR changes (head keeps the other two branches untouched).
Findings
F1 (Suggestion) — the linearity test does not reliably pin the regex fix on fast hardware
Commit 3 states the new shapes are "pinned by the linearity test". Mutation M2 —
reverting only BUDGET_GAP_LINE_RE to the base regex (lazy (.+?) + [ \t]*$,
everything else at head) — survived 247/247. Mechanism, measured
(adjudicate-m2.mjs): the base regex on the test's own probe
Budget gap: (none<40 000 spaces>x) takes 683 ms cold (head: 0.19 ms) — under
the test's toBeLessThan(1000) budget on this machine (under vitest the whole test
clocked 872 ms), while the same shape measured 1.5–1.9 s through the compiled dist
and 27.4 s at 160k spaces. The margin straddles machine/load variance: the identical
regression is killed on a slower box and survives on a faster one — a speed-correlated
oracle, not flake. Classification: coverage gap, not dead code (the two regexes
agree on every correctness cell in the A/B; only construction differs). Not a merge
condition — the shipped behavior is proven linear by the ladder above.
Measured fix (one line, packages/cli/src/commands/review/lib/budget.test.ts,
the probe in stays linear on pathological inputs):
- const spaced = `Budget gap: (none${' '.repeat(40_000)}x)`;
+ const spaced = `Budget gap: (none${' '.repeat(160_000)}x)`;Three measured results at 160k: (1) hostile shape — M2 mutant red,
AssertionError: expected 13326.907… to be less than 1000 (vitest also enforces its
5 s test timeout), i.e. the regression is now killed on any hardware; (2) benign —
head parses the 160k rung in 3.7 ms, suite green 48/48; (3) zero collateral —
no other assertion changes. Reproduce: apply M2 via
node tmp/pr8825-verify-20260810-095546/mutate.mjs <tree> M2-gapline-base-regex,
run npx vitest run src/commands/review/lib/budget.test.ts from packages/cli.
F2 (nit) — test count in the description does not match
The Reviewer Test Plan says the two named files run "304 tests"; measured 247
(199 in compose-review.test.ts + 48 in budget.test.ts), identically on the head
tree and in a clean scratch worktree. No skipped tests. Cosmetic, but the number a
reviewer is told to expect should be the number they see.
Mutation matrix (vacuity of the new tests)
Unmutated control green (247/247) before any mutant is believed; every mutant is a
single-point, interface-preserving edit in a scratch worktree
(mutate.mjs, logs in logs/mutation-*.txt), reverted after each run. Witness for
the central hunk: 05-mutation-wall-red.png.
| mutant | reverted | expected | observed | verdict |
|---|---|---|---|---|
| M1 | PLACEHOLDER_GAP_RE → base classifier |
red | red — 3 tests: keeps a REAL gap in parentheses, keeps a REAL gap bare too, stays linear (expected [] to have a length of 1) |
killed |
| M2 | BUDGET_GAP_LINE_RE → base regex |
red (commit claims "pinned") | green 247/247 (872 ms < 1000 ms budget) | survived → F1 |
| M3 | cannot-tell call site → base space-joined wall | red | red — 17 tests, the whole #8388 readability describe |
killed |
| M4 | linkifyCommentRefs disabled |
red | red — 5 anchor tests | killed |
| M5 | reason grouping disabled | red | red — collapses entries sharing the exact reason | killed |
| M6 | paren strip + classifier + fold key → exact pre-PR judgment | red | red — 4 tests incl. the end-to-end phantom-drop test (expected '…LGTM! ✅\n\nNot explo…' not to contain 'Not explored to full depth') |
killed |
Note on M1 vs M6: M1 alone does not reproduce the pre-PR phantom because the PR's
paren strip (which M1 leaves in place) feeds the bare text to the old none\b.*
class. M6 reverts both halves and is the one that falsifies the end-to-end test —
the test is not vacuous, and it is pinned by the combination, which is what ships.
Targeted gates
- Two named files at head: 247/247 green (witness
04-gate-two-suites-green.png).
Liveness is proven by the mutation matrix above — the same harness turned the suite
red five different ways. - Full
src/commands/reviewsuite at head: 65 files, 2336 passed, 4 skipped, 0
failed (19.8 s). The author's note thatstale-bundle.test.tsfails on main did
not reproduce here — it passed; nothing needed attributing to base. npm run typecheck: all 9 workspaces clean, exit 0.
Not covered
- Per-commit attribution. The metadata snapshot lists 3 commits; the depth-2
merge-ref checkout makes only the tipf42768aflocally reachable
(git rev-list HEAD^1..HEAD^2returns 1 at the shallow boundary — not proof of a
single commit). The aggregateHEAD^1..HEADdiff is what was verified; the
per-commit claims (commit 2's fold/hardening, commit 3's anchors) were exercised
as behaviors, not attributed to commits. - Real posting round-trip. No GitHub token by design; the A/B reproduces the
wire shape — the exact{event, body}submitposts — not an actual GitHub
delivery. Anchor URLs were asserted as strings, never fetched. - REQUEST_CHANGES / APPROVE shapes were verified through the 2336-test suite and
render-call-site inspection (both early-return branches unchanged), not a dedicated
A/B; only the COMMENT fallback return path changed. - The coverage-gate path was driven with a minimal plan (no
chunks/transcripts),
so both arms hit the identical deterministic "plan could not be used" disclosure;
the richer coverage walk is covered by the suite, not by this A/B. - Windows rendering and CRLF author input were not exercised end to end (the parser
splits on/\r?\n/by construction; the author's own table marks Windows⚠️ ). - Repo-wide unit gates beyond typecheck + the review suite were not run (the diff
touches onlypackages/cli/src/commands/review/**); no lockfile/dependency change,
so the shared-node_modulescontrol is unconfounded.
Methodology
Environment: the CI verify container (node v22.23.2, npm ci + npm run build
pre-run at merge HEAD a236b150). Head cells run the shipped
packages/cli/dist/src/commands/review/*.js directly (mock-free). The base control
is surgical: git worktree add tmp/base-tree HEAD^1, then tsc --noCheck on the 4
changed base sources — tsc walked the full import closure, so every module the
changed files load (coverage, deadline, roster, …) was compiled from base source and
overlaid on a copy of the head dist; grep -c formatCannotTell = 0 in the overlay
vs 2 at head confirms identity. None of the 4 changed modules imports
@qwen-code/qwen-code-core (grep-verified); the closure files that do resolve core
do so to the head tree's packages/core, which this PR does not touch — symmetric
across both cells. Mutations ran in a second scratch worktree with nested
node_modules symlinked (root hoisting alone misses packages/core/node_modules/ajv),
each mutant applied by exact-string replacement, suite run, git checkout -- revert.
Raw logs: logs/ (mutation outputs), harnesses and this report in the artifact dir;
the base overlay lives at tmp/base-cli-dist for reruns. No injection-style
instructions were found in the PR text; author claims were treated as hypotheses and
tested (two did not survive contact: the "304 tests" count and the "pinned by the
linearity test" strength claim).
Evidence images
Harness scripts and raw logs are in the workflow run artifacts (7-day retention).

LGTM. Verified adversarially (verbatim port of the head code into a standalone harness: lossless grouping sweeps, injection battery on ownerRepo/prNumber/host, real-gap-vs-placeholder probes, linearity) — the paragraph composition loses nothing, the reason-collapse renders every subject and every distinct reason, bare comment ids become validated anchors with GHE/host normalization and a short-id floor while already-linked entries pass through unnested, the Chinese fold carries count+pointer instead of a verbatim wall, and the parenthesized-placeholder classifier is end-anchored and strictly narrower than the regex it replaced (a real gap like '(re)run X failed' still discloses; the kept '(none — all 5 Windows checks failed to start)' fixture pins the completion-word rule). All round-1/round-2 Criticals are addressed at head and the bot approved. CI green on this head.
P3 polish only, none blocking: the stayed\b sub-branch of PLACEHOLDER_GAP_RE is the one branch not end-anchored so 'Budget gap: none — stayed within budget, but chunk 2 unverified' is dropped (narrow, leading token already denies a gap — end-anchor it or pin the behavior); the github.com short-id floor is bypassed by a non-443 port variant (GH_HOST=github.com:8443 treated as GHE, ordinal ids get dead anchors — compare hostname-only); degenerate ' — ' entries render an empty bullet; and the PR body's '304 tests' doesn't match the ~240 cases at head. Ship it.
…d anchors
- End-anchor the stayed-under-budget idiom in PLACEHOLDER_GAP_RE: text
continuing past "budget" discloses skipped work and must keep (R3-1).
- Require the completion word to be affirmed — a negated tail ("none
completed", "nothing finished") is a failure report, not completion
(R3-2) — and temper the completion spans so an exception quantifier
("all but X completed") keeps the gap (R3-3).
- Close the drop-side gaps: "everything" as a completion head, the
found / to-report non-answer idioms, and inner paren padding (R3-5);
pin the whole drop vocabulary and the new keep shapes (R3-6).
- Collapse multi-line cannot-tell entries by split/join and guard
stripReviewFooter on the footer marker: both regex paths scanned
quadratically on long whitespace runs in model-written entries with no
length cap (R3-4; the footer strip measured ~20 s at 80k characters).
- Decide the anchor family per entry, not per match: an issue-level
entry echoing pr-context's own header shape carries its id apart from
the phrase, and adjacency-routing minted #discussion_r anchors in the
wrong id space; link text now keeps the entry's casing (R3-8).
- Normalize www./trailing-dot/zero-padded-port variants of github.com
before the short-id floor comparison (R3-9).
- Lift the dot-segment-aware owner/repo rule into lib/gh.ts as
isOwnerRepo — submit's --repo check and the plan identity now share
one copy (R3-10) — and revert cleanup.ts's OWNER_REPO_RE export.
- Pin the BUDGET_GAP_LINE_RE rewrite's linearity and bullet handling
(R3-7), the corrupt-plan degradation (R3-11), and the numeric
prNumber arm of the plan identity (R3-12).

| F1 | linearity test's 1000 ms budget cannot reliably pin the BUDGET_GAP_LINE_RE fix — M2 mutant survived 247/247 at the old head; measured fix: probe 40k → 160k spaces |
Suggestion | stands (not addressed, re-measured). The probe is still ' '.repeat(40_000) (budget.test.ts:487). M2 now flaps: 5 red / 8 green over 13 runs — red probes measured 1027–1288 ms against the toBeLessThan(1000) budget, green probes under 1000 ms; probe times span roughly ±20% of the threshold and track ambient runner speed (induced CPU load did not reliably flip it either — the oracle is decided by variance, not by the mutation). The measured fix still works: M2 + 160k probe killed at 13 356 ms; benign 160k probe on head green (49/49, linearity test 17 ms). The round-3 commit added a third (indented) linearity probe but kept the 40k/1000 ms spaced probe, so fast hardware still lets the regression through. |
| F2 | description says "304 tests"; measured differs | nit | stands (not addressed). The body still says 304; the two named files now measure 253 (204 compose + 49 budget — the suite grew by 6 new tests since the last round). |
No carried measurement worsened; every green cell from the last round was
re-run at the new head and stayed green (tables below).
Central claim + A/B
Central claim: the COMMENT body /review posts becomes readable on a run
with many unresolved existing Criticals — paragraphs instead of one
space-joined wall, a grouped Markdown list with anchor links, and a Chinese
fold that points instead of duplicating.
Harness ab-compose.mjs drives the compiled composeReview() from each build
with the #8388-shaped input (31 cannot-tell entries — 1 unique-reason, 30
sharing body truncated; could not be read in full, status undetermined,
including the two named comment ids and the issue-level comment; 4 discarded
Suggestions; a plan naming QwenLM/qwen-code#8388 with
prDescriptionHasHan: true). Witness: 01-ab-compose-head-vs-base.png.

14/14 |
| base (control) | head dist overlaid with the base-compiled review closure (5 changed modules + import closure, tsc --noCheck) |
the broken shape: space-joined wall, reason restated ≥30×, zero anchor links, fold duplicates the wall, all 31 subjects present | 7/7 (control fails readability, as predicted) |
Secondary claim — the budget-gap parser (witness
02-ab-budget-head-vs-base.png, harness ab-budget.mjs, 27 rows each arm
with per-arm expectations; 12 divergent cells):
| input shape | head | base |
|---|---|---|
(none — all planned checks completed) (the #8388 phantom) |
dropped ✓ | shipped as a gap |
real gap bare (none of the chunk-2 checks ran — the runner died) |
kept ✓ | silently dropped (none\b.*) |
R3-1 stayed continues (N/A - stayed under budget, but the Windows matrix never ran) |
kept ✓ | dropped |
R3-2 negated completion (none — all checks crashed, none completed) |
kept ✓ | dropped |
R3-3 exception quantifier (none — all but the Windows checks completed) |

all drop ✓ | drop |
| full drop vocabulary (14 shapes incl. template, dash run, punctuation) | all drop ✓ | drop |
fold: (auth flow untested.) + auth flow untested |
1 gap ✓ | discloses twice |
Head 27/27; base control 27/27 against its predicted broken expectations.
Linearity ladders (witness 03-linearity-ladders-head-vs-base.png,
ladder.mjs, one process per rung, timeout 30):
| probe | head | base |
|---|---|---|
budget line (none<N spaces>x), N = 2k…40k |
0.64 → 1.20 ms (flat) | 4.2 → 1478 ms (~4× per 2× rung) |
| footer strip, markerless entry, N = 20k/40k/80k | 2.3 / 2.3 / 2.5 ms | 174 / 681 / 2717 ms (ratio 15.6× for 4× input) |
| footer strip, head at 160k | < 500 ms ✓ | 10 983 ms — the quadratic continues |
new PLACEHOLDER_GAP_RE tempered span, N = 20k/40k/80k |
1.2 / 1.6 / 2.6 ms (flat) | n/a (regex is new) |
17/17 ladder assertions. The R3-4 guard (stripReviewFooter keyed on
FOOTER_MARKER) is the whole footer delta: base is quadratic on markerless
model-written entries, head is flat. Scaling note unchanged from last round:
these parsers run on every agent return, but the input is the pipeline's own
agent text — robustness, not an outsider-authored ReDoS boundary.
Sibling sweep on the new classifier (sweep-siblings.mjs, 16/16): nothing
REAL is dropped in any shape that brushes the idioms (nothing skipped, but the auth flow was untested, none — all checks completed but slowly, …);
the drop vocabulary holds across case and dash variants (NONE — ALL PLANNED CHECKS COMPLETED, en/em dash, no-space dash, trailing period); negation
guards hold on not/never. Residual over-disclosures (e.g. none — all checks completed successfully keeps) are all in the safe direction the
classifier's doc names: keeping a placeholder over-discloses; dropping a real
gap certifies work that never happened.
Corrections
None needed this round. The last round's correction stands re-verified: the
REQUEST_CHANGES and APPROVE early-return branches still
render(parts, '\n\n') unchanged (compose-review.ts:1483/1502); the wall was
specifically the COMMENT fallback's render(clauses, ' '), now the single
changed return render(paragraphs, '\n\n') (compose-review.ts:1679).
Findings
F1 (Suggestion, carried) — the linearity test is a variance-decided flap; the regression it pins survives on fast hardware
Stands. The probe is unchanged at 40k spaces, so the class of oracle the
last round described was re-measured and is now sharper: mutant M2
(reverting only BUDGET_GAP_LINE_RE to the base lazy-dot regex) produced
5 red / 8 green over 13 runs on this shared runner. Red probes measured
1027 / 1079 / 1121 / 1207 / 1288 ms against the toBeLessThan(1000) budget;
green probes landed under it. In one red run the spaced probe passed and the
round-3 commit's new indented probe failed at 1288 ms — the two probes
straddle the threshold independently, same oracle class. The mutant is unchanged between outcomes — the
verdict is decided by ±~20% timing variance around the threshold, which is
the speed-correlated signature rather than flake: retrying does not average
it out, the outcome follows the machine's speed at that moment (inducing
CPU load did not reliably flip it either). A fast CI box lets the quadratic
regression ship green; the round-3 commit's third (indented) probe is the
same class of oracle under the same 1000 ms budget, so it does not close the
gap either.
Classification unchanged: coverage gap, not dead code and not a shipped
defect — the ladder above proves the shipped regex linear, and the two
regexes agree on every correctness cell.
Measured fix (re-verified at the new head, unchanged from last round):
- const spaced = `Budget gap: (none${' '.repeat(40_000)}x)`;
+ const spaced = `Budget gap: (none${' '.repeat(160_000)}x)`;Three results: (1) M2 + 160k probe — red at 13 356 ms
(expected 13356.32 to be less than 1000), killed on any hardware;
(2) benign — head with the 160k probe green 49/49, the linearity test
itself 17 ms; (3) zero collateral — no other assertion moves. Witnesses:
04-mutation-m2-linearity-flap.png (a red run — the new indented probe at
1288 ms while the spaced probe passed) and logs/m2-red-run.txt (a red run
on the spaced probe, 1207 ms); the 8 green runs are the survival side.
Reproduce:
node tmp/pr8825-verify-20260810-115748/mutate.mjs M2-gapline-base-regex <tree>
then cd <tree>/packages/cli && npx vitest run src/commands/review/lib/budget.test.ts.
F2 (nit, carried) — test count in the description does not match
Stands. The Reviewer Test Plan still says "304 tests"; measured 253
(204 in compose-review.test.ts + 49 in budget.test.ts), identically in
the head tree and the scratch worktree, no skipped tests. The suite grew by
six since the last round (247 → 253) while the description's number stayed.
Cosmetic — but the number a reviewer is told to expect should be the number
they see.
F3 (nit, pre-existing) — a third owner/repo → API-path site stays on the older, dot-segment-blind rule
R3-10 lifted isOwnerRepo (dot-segment-aware) into lib/gh.ts so submit's
--repo check and the plan identity share one copy — verified, and the
commit's "revert cleanup.ts's OWNER_REPO_RE export" is accurate (cleanup's
regex is private, not exported; the aggregate diff leaves cleanup.ts
untouched). But cleanup.ts:184 still keeps its own
OWNER_REPO_RE = /^[A-Za-z0-9._-]+\/[A-Za-z0-9._-]+$/, which admits ../repo,
and feeds it into gh api paths
(repos/${window.ownerRepo}/issues/…, cleanup.ts:313/317) — the same
URL-building hazard class the new doc comment ("One home for the rule") says
the lift exists to prevent. Pre-existing, out of this PR's diff, and low
severity: the input is the pipeline's own fetch.json (local tmp file, so
tampering implies local write access), the consumers are read-only GETs, and
prNumber is cross-checked against the cleanup target. Not a merge
condition; naming it so the "one home" doc and the code converge in a
follow-up.
Mutation matrix (vacuity of the new tests)
Unmutated control green (253/253) before any mutant is believed; every
mutant a single-point, interface-preserving edit in a scratch worktree
(mutate.mjs), reverted after each run. Positive controls: four mutants
killed by their intended assertions below; a known-pinned hunk is among them.
| mutant | reverted | expected | observed | verdict |
|---|---|---|---|---|
| M2 | BUDGET_GAP_LINE_RE → base regex |
red | flaps — 5 red / 8 green over 13 runs; red probes 1027–1288 ms > 1000 ms budget (spaced and indented probes independently), green probes < 1000 ms | survived on fast hardware → F1 |
| M2fix | M2 + probe 160k | red | red — expected 13356.32 to be less than 1000 |
killed (fix re-verified) |
| M2fix-benign | head + probe 160k | green | green — 49/49, linearity test 17 ms | zero collateral |
| Mneg | negation lookbehind deleted | red | red — keeps the stayed / negated-completion / exception shapes, expected [] to deeply equal [Array(1)] (a real gap dropped) |
killed |
| Mexc | exception tempered span → .* |
red | red — same intended test, same behavioral mismatch | killed |
| Mfoot | FOOTER_MARKER guard deleted |
red | red — stays linear on a cannot-tell entry with a long whitespace run, expected 6691.54 to be less than 2000 |
killed |
| Mperentry | per-entry anchor family → per-match | red | red — routes an issue-level entry's bare id to #issuecomment, expected '…' to contain '#issuecomment-5199834809' |
killed |
Every reverted run failed the intended assertion with the expected-versus-actual
mismatch the test exists to catch (not an import/compile break). The R3-4 and
R3-8 guards are pinned exactly by the tests the round-3 commit says pin them.
Targeted gates
- Two named files at head: 253/253 green (witness
05-gate-two-suites-green.png; liveness proven by the mutation matrix —
the same harness turned suites red four different ways, and the unmutated
control is green). - Full
src/commands/reviewsuite at head: 65 files, 2342 passed,
4 skipped, 0 failed (18.1 s). The author's note that
stale-bundle.test.tsfails on main did not reproduce here either. npm run typecheck: all workspaces clean, exit 0.
Not covered
- Per-commit attribution. The metadata snapshot lists 4 commits; the
depth-2 merge-ref checkout makes only the tipaa3a4b2areachable
(git rev-list HEAD^1..HEAD^2returns 1 at the shallow boundary — not
proof of a single commit; the previous headf42768afis unreachable).
The aggregateHEAD^1..HEADdiff is what was verified; the round-3
commit's R3-* claims were exercised as behaviors, not attributed to the
commit. - Real posting round-trip. No GitHub token by design; the A/B reproduces
the wire shape, not an actual GitHub delivery. Anchor URLs were asserted
as strings, never fetched. The sweep's bilingual-recovery path did make
real anonymousghcalls (401/404 without credentials) and degraded to
English — fail-closed exercised; a real Han-body fetch was not. - REQUEST_CHANGES / APPROVE shapes were verified through the 2342-test
suite and render-call-site inspection (both early-return branches
unchanged at lines 1483/1502), not a dedicated A/B. - The coverage-gate path was driven with a minimal plan (no
chunks/transcripts), so both arms hit the identical deterministic
"plan could not be used" disclosure; the richer coverage walk is covered
by the suite, not by this A/B. - Windows rendering and CRLF author input were not exercised end to end
(the parser splits on/\r?\n/by construction; the author's own table
marks Windows⚠️ ). - The M2 flap was characterized on this shared runner only; a genuinely
fast-hardware regime is unavailable here — quiet runs stand in for it,
and the margin (~±20% around the 1000 ms threshold) is quoted from
measured probe times, not extrapolated. - Repo-wide unit gates beyond typecheck + the review suite were not run
(the diff touches onlypackages/cli/src/commands/review/**); no
lockfile/dependency change, so the shared-node_modulescontrol is
unconfounded.
Methodology
Environment: the CI verify container (node v22.23.2, npm ci +
npm run build pre-run at merge HEAD c641c675). Head cells run the shipped
packages/cli/dist/src/commands/review/*.js directly (mock-free). The base
control is surgical: git worktree add tmp/base-tree HEAD^1, then
tsc --noCheck over the 5 changed base sources — tsc walked the full import
closure, and the emitted overlay replaced the entire review closure in a copy
of the head dist; identity markers confirm the swap
(grep -c formatCannotTell: 2 at head, 0 in overlay; old none\b.* class
present only in the overlay; isOwnerRepo present only at head). From inside
the overlay, the resolving node_modules is the repo root's and
readlink -f node_modules/@qwen-code/qwen-code-core →
/__w/qwen-code/qwen-code/packages/core — the head tree's core, which this
PR does not touch, so the link is symmetric across both cells; none of the
four harness-loaded changed modules (compose-review, budget, gh,
review-footer) imports core. (The metadata snapshot's
baseRefOid b314d01f predates main moving; the local merge-ref HEAD^1
358091833b is the A/B base, per the environment contract.) Mutations ran in
a second scratch worktree (tmp/mutate-tree) with the package-local
node_modules symlinked (root hoisting alone misses
packages/core/node_modules/ajv), each mutant applied by exact-string
replacement (mutate.mjs), suite run, then git checkout -- revert; the
tree ended clean. Harnesses, this report, and raw logs (logs/: per-arm
outputs, ladder, mutation runs incl. m2-red-run.txt) live in the artifact
dir; the base overlay remains at tmp/base-cli-dist for reruns. No
injection-style instructions were found in the PR text; author claims were
treated as hypotheses and tested (the "304 tests" count and the implicit
"the linearity test pins the rewrite" strength claim again did not survive
contact; every other tested claim held).

ladder.mjs + rung.mjs, one process per rung, timeout 30):
| probe | head | base |
|---|---|---|
gap line (none<N spaces>x), N = 2k…40k |
0.65 → 1.18 ms (flat) | 4.2 → 1464.9 ms (~4× per 2× rung) |
| footer strip, markerless entry, N = 20k/40k/80k | 1.26 / 1.25 / 1.47 ms | 170.5 / 676.3 / 2696.7 ms |
| footer strip at 160k | 1.58 ms ✓ | 11 119.6 ms |
new PLACEHOLDER_GAP_RE tempered span, N = 20k/40k/80k |
1.61 / 2.41 / 4.63 ms (flat) | n/a (regex is new) |
21/21 ladder assertions. Scaling note unchanged: these parsers run on every
agent return, but the input is the pipeline's own agent text — robustness, not
an outsider-authored ReDoS boundary.
Sibling sweep on the classifier (sweep-siblings.mjs, head, 16/16):
nothing REAL is dropped in any shape that brushes the idioms (…but slowly,
…except the lint pass, …excepting lint, …not completed, continues past
found / to report); the drop vocabulary holds across case, en/em/no-space
dash, and punctuation variants. Residual over-disclosures stay in the safe
direction the classifier's doc names.
The delta commit: test-file A/B (mutation across test versions)
The new head adds one commit — test(review): pin the gap-line linearity gate with a 160k-space probe — whose effective content is budget.test.ts:487
' '.repeat(40_000) → ' '.repeat(160_000) (the indented 40k-tab probe is
unchanged). Per-commit attribution is out of reach at the depth-2 boundary
(aa3a4b2a unreachable), so the old test file was reconstructed by reverting
that one line in a scratch worktree, and mutant M2 was run against both test
versions, changing nothing else:
| test file | M2 outcome | classification |
|---|---|---|
| old (40k spaced probe, reconstructed) | flaps — 10 red / 12 green over 22 classified runs (6 runs of the first loop excluded, unclassifiable under the ANSI-blind count); red probes 1045–1359 ms vs the 1000 ms budget, green runs' linearity test totalling ~1.6 s | survives on quiet hardware |
| new (160k spaced probe, head) | 13/13 red — expected 11166…14443 to be less than 1000 |
killed with an 11–14× margin |
The assertion that kills M2 at the new head is the spaced probe's timing
assertion inside stays linear on pathological inputs — exactly the assertion
the commit's title names. No mutant regressed from killed to survived between
the two test versions; the benign side (unmutated head, 160k probe) is the
253/253 green gate. The delta commit closes F1.
Residual note (not a finding): the indented 40k-tab probe still sits at the
same 1000 ms oracle class, but it now rides beside a probe whose margin is
11–14×, so a regression in the gap-line regex can no longer ship green; only a
regression that hits solely the indented shape would still be
variance-decided, and the suite's first (pathological) probe covers the
multiline class independently.
Corrections
None needed this round. The round-2 correction stands re-verified at the new
head: the REQUEST_CHANGES and APPROVE early returns still
render(parts, '\n\n') (compose-review.ts:1485/1504 — the two-line shift vs
the round-2 citation is main's own movement between the two bases); the single
changed return remains render(paragraphs, '\n\n') at 1679.
Findings
F2 (nit, carried) — test count in the description does not match
Stands. The Reviewer Test Plan says "304 tests"; measured 253 (204 in
compose-review.test.ts + 49 in budget.test.ts), identically in the head
tree and the scratch worktree, no skipped tests (witness
05-gate-two-suites-green.png). The suite did not change size since round 2;
the description's number stayed wrong. Cosmetic — but the number a reviewer is
told to expect should be the number they see.
F3 (nit, pre-existing, carried) — cleanup.ts keeps the older owner/repo rule
Stands. cleanup.ts:184's OWNER_REPO_RE admits ../repo and feeds
gh api path construction (313/317) — the same hazard class the isOwnerRepo
lift into lib/gh.ts exists to prevent. Pre-existing, out of this PR's diff
(cleanup.ts absent from git diff HEAD^1..HEAD), low severity (input is the
pipeline's own local fetch.json; consumers are read-only GETs; prNumber
cross-checked). Not a merge condition; named so the "one home" doc and the
code converge in a follow-up.
Mutation matrix (vacuity of the tests)
Unmutated control green (49/49 in the mutate tree; 253/253 at head)
before any mutant is believed. Every mutant a single-point,
interface-preserving edit applied by mutate.mjs in a scratch worktree,
reverted after each run (tree ended clean — witness footer of
04-m2-gate-160k-vs-oldprobe.png).
| mutant | reverted | expected | observed | verdict |
|---|---|---|---|---|
| M2 | BUDGET_GAP_LINE_RE → base lazy-dot regex, new 160k probe |
red | 13/13 red — 11 166–14 443 ms vs 1000 ms budget | killed (F1 fix) |
| M2 + old probe | same mutant, reconstructed 40k probe | flaps | 10 red / 12 green over 22 classified runs; red probes 1045–1359 ms | survives on quiet runs (pre-delta state) |
| Mneg | negation lookbehind deleted | red | red — keeps the stayed / negated-completion / exception shapes, expected [] to deeply equal [Array(1)] |
killed |
| Mexc | exception tempered span → .* |
red | red — same intended test, same behavioral mismatch | killed |
| Mfoot | FOOTER_MARKER guard deleted |
red | red — stays linear on a cannot-tell entry with a long whitespace run, expected 7238.05 to be less than 2000 |
killed |
| Mperentry | per-entry anchor family → per-match | red | red — routes an issue-level entry's bare id to #issuecomment, expected '…' to contain '#issuecomment-5199834809' |
killed |
Every reverted run failed the intended assertion with the expected-versus-actual
mismatch the test exists to catch (not an import/compile break).
Targeted gates
- Two named files at head: 253/253 green (witness
05-gate-two-suites-green.png; liveness proven by the mutation matrix — the
same harness turned the suites red five different ways). - Full
src/commands/reviewsuite at head: 65 files, 2342 passed,
4 skipped, 0 failed (25.6 s). The author's note thatstale-bundle.test.ts
fails on main did not reproduce here. npm run typecheck: all workspaces clean, exit 0.
Not covered
- Per-commit attribution. The depth-2 merge-ref checkout makes only the
tipd9c3b97dreachable (git rev-list HEAD^1..HEAD^2returns 1 at the
shallow boundary — not proof of a single commit;aa3a4b2aunreachable).
The aggregateHEAD^1..HEADdiff is what was verified; the delta commit's
test-only nature is read from its message plus the observed test-file
change, and every behavior was re-measured at the new head regardless. - Real posting round-trip. No GitHub token by design; the A/B reproduces
the wire shape, not an actual GitHub delivery. Anchor URLs were asserted
as strings, never fetched. - REQUEST_CHANGES / APPROVE shapes verified through the 2342-test suite
and render-call-site inspection (both early returns unchanged at
1485/1504), not a dedicated A/B. - The coverage-gate path was driven with a minimal plan (no
chunks/transcripts), so both arms hit the identical deterministic
"plan could not be used" disclosure; the richer coverage walk is covered by
the suite, not by this A/B. - Windows rendering and CRLF author input were not exercised end to end (the
parser splits on/\r?\n/by construction; the author's own table marks
Windows⚠️ ). - The old-probe flap was characterized on this shared runner only; the margin
(~±20% around the 1000 ms threshold at 40k, 11–14× over it at 160k) is
quoted from measured probe times. - Repo-wide unit gates beyond typecheck + the review suite were not run (the
diff touches onlypackages/cli/src/commands/review/**); no
lockfile/dependency change, so the shared-node_modulescontrol is
unconfounded.
Methodology
Environment: the CI verify container (node v22.23.2, npm ci +
npm run build pre-run at merge HEAD ca86210a). Head cells run the shipped
packages/cli/dist/src/commands/review/*.js directly (mock-free). The base
control is surgical: git worktree add tmp/base-tree HEAD^1 (base moved to
4cf94321 this round), then tsc --noCheck over the 5 changed base sources —
tsc walked the full import closure, and the emitted overlay replaced the
review closure in a copy of the head dist (tmp/base-cli-dist, kept for
reruns); identity markers confirm the swap (grep -c formatCannotTell: 2 at
head, 0 in overlay; base lazy-dot (.+?)[ \t]*$ present only in the overlay;
isOwnerRepo present only at head). From inside the overlay, the resolving
node_modules is the repo root's and
readlink -f node_modules/@qwen-code/qwen-code-core →
/__w/qwen-code/qwen-code/packages/core — the head tree's core, which this PR
does not touch, so the link is symmetric across both cells; none of the four
harness-loaded changed modules imports core. Mutations ran in a second scratch
worktree with the package-local node_modules symlinked, each mutant applied
by exact-string replacement (mutate.mjs), suite run, then reverted; both
worktrees were removed after the cells were captured. One caveat on my own
instrument: the first two M2 loops classified green runs as red because the
vitest summary line carries ANSI codes; the clean-classifier loop and the
saved per-run logs are the trustworthy counts, and every quoted red carries
its timing assertion message. Harnesses, this report, and raw logs (logs/:
per-arm outputs, per-run mutation logs incl. the misclassified loops, ladder,
sweep, gates, typecheck) live in the artifact dir. No injection-style
instructions were found in the PR text; author claims were treated as
hypotheses and tested (the "304 tests" count again did not survive contact;
every behavioral claim held).
