From 375ff497525f1c65287222a9090b78d3551250ce Mon Sep 17 00:00:00 2001 From: Shaojin Wen Date: Thu, 20 Aug 2026 23:50:42 +0000 Subject: [PATCH 1/4] feat(review): tell the author why a review loop is not settling (#9461) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat(review): tell the author why a review loop is not settling The convergence advisory design's diagnosis half (#9278), reading the telemetry #9413 started recording. A push-triggered review plus an agent addressing its findings is a feedback loop whose gain can exceed 1, and measured on this repository the loop has carried PRs to hundreds of open threads — one closed unmerged at ~500. The posting floor damps the volume; nothing told anyone WHY a particular loop was not settling. Two signals fire the observation, both comparisons between this pull request's own rounds. Recurrence: a file that carried a finding in an earlier round and carries more now, joined by FILE and deterministically, with the prior rounds read off the carried ledger ids so the rendered sentence is checkable against the PR's own history (title similarity was considered and dropped — model-written, 80-char-capped titles are noise at exactly the length where a match would matter). And volume that is not shrinking, from round 3, because two rounds give one step and a step is not a trend. There is no threshold anywhere in it. A volume bar is somebody's policy, and a policy the tool owns is one it would have to defend on repositories it knows nothing about: a PR diverging at 40 comments deserves the reading a threshold of 100 would have delayed, and a large review whose findings are shrinking deserves no interruption at all. It decides nothing. No finding is withheld, no verdict capped, no cap state added — the paragraph says so in its own last sentence. The recommendations stay at the process level (triage the cause, split an independent cluster, batch the fixes, drop the floor) and never prescribe how code should be restructured, because this module cannot verify such a claim and an unverifiable claim is what the rest of this pipeline refuses to post. A round that looks healthy produces no diagnosis at all rather than an empty section. * fix(review): a loop that posted nothing is settled, not stalled (triage round 1) Both triage nits, and the second was a real inversion. `0 >= 0` is arithmetically "not shrinking" and semantically its opposite: a round that posted nothing is precisely where a settling loop lands, so the volume signal narrated "the volume is not falling" at the moment it had finished falling — flagging the settled state as the unsettled one. The signal is about a loop still producing comments at an undiminished rate, so it now requires this round to have produced some. Both zero shapes are pinned: flat at zero, and the fall to zero from above. The Approve branch's separator condition now counts the convergence block. That combination is unreachable — an APPROVE is composed from zero findings, so neither signal can fire there — and it is listed anyway, with the reason recorded: a condition that is right only because another rule makes its input impossible is a trap for whoever changes that other rule. (A test asserting it was written and then deleted rather than shipped: it could only have passed vacuously.) * fix(review): harden the convergence diagnosis against round 1 review Round 1 on #9461 found two blockers and fifteen suggestions. The two blockers: - The diagnosis received an unclamped `prevRound + 1` while every other public round surface in the composer clamps to `LEDGER_MAX_ROUND`, so at the cap the prose named round 10001 beside a marker stamping 10000. - Cluster paths are PR-controlled and were spliced into the posted body inside hand-spelled backticks. A filename carrying a backtick or a newline broke out of the code span and rendered as live Markdown — a working @mention, a forged body line — in a body this bot posts under its own identity. `mdField` moves to `lib/md-field.ts` and both templates go through it. Signal correctness: - Carried re-posts of still-standing findings no longer count as fresh activity. Step 6 re-posts every unfixed ledger Critical under its original id, so one unfixed blocker fired both signals every round at exactly the steady state they exist to distinguish from divergence. - The volume trend needs a non-zero predecessor: `N >= 0` is true for every N, so restarting from a settled round fired on the healthiest shape there is. - Drafted paths are canonicalised to `LEDGER_MAX_FILE`, the cap the other side of the join already applies, so the signal is no longer blind to paths past 200 characters. - The previous work list is gated on its own round, like the volume already was; a side file with no usable round no longer seeds citations. Evidence and advice are now qualified rather than presented bare: a truncated work list (`dropped > 0`) and one recovered from another account's marker are both disclosed in the rendered sentence, and the floor recommendation is dropped when the round already resolves to `--severity-floor critical`. `pr-context` persists that provenance. Also: the block carries `trim: 1` so an advisory paragraph yields before the disclosures that qualify the verdict; the path tie-break compares code units instead of consulting the runtime locale; the English closing claim is scoped to the observation the way its Chinese twin already was; the `(body)`/`(unknown)` pseudo-paths and the carried-id readback each get one shared statement instead of two; and the diagnosis is composed beside `postedInline` so its count and the marker's cannot drift. Seventeen mutations, one per load-bearing decision, each verified to turn a named test red. * fix(review): close the round 2 findings on the convergence diagnosis Three blockers: - The overflow ladder's notice surfaces all key on the trim RANK, not on what actually dropped, so sharing rank 1 with the deferral list made a round that shed only the convergence paragraph announce a "deferred-findings list" that never existed and point the author at artifact entries that do not exist. The block gets its own rank, shed before every other, named for itself and carrying no artifact pointer. - `parseLedger`'s squat filter is anchored and untrimmed while every reader downstream trims, so an id like ` R9999-1` passed the filter that exists to stop it and then took full effect — pre-claiming the next round's id prefix and citing a round no account ever ran. Admission is now the whole grammar, at the single entry point; `LEDGER_ID_SHAPE` moves to ledger.ts and presubmit imports it rather than restating it. - The foreign-provenance caveat was gated on the recurrence reading, but the previous round's VOLUME comes from the same marker and the volume-only branch cites it as this loop's baseline. A foreign winner now loses `posted`/`prevPosted`/`floor` at the recovery seam the way it already loses the anchor, and the caveat attaches to any reading that cites previous-round evidence. The volume trend also stops reading a POSTURE change as loop divergence: the round's resolved floor is stamped beside the volume it qualifies and sheds with it, and a previous round under a different floor makes the trend unevaluable rather than true. A floor never recorded is not a floor that differs, so pre-field markers evaluate as before. Also: the advice names an auto-resolved floor the way the enforcement note in the same body does, instead of claiming a `--severity-floor critical` flag nobody passed; the pseudo-paths become a structural flag on the finding, so a real file named `(body)` clusters like the file it is; the re-post exclusion fails toward "carried" where the id space collides at the round cap; and `mdField` no longer emits a bare backtick run for a value that strips to empty, which two planted filenames could pair into a span around the bot's own prose. Fourteen mutations, one per load-bearing decision, each verified to turn a named test red. * fix(review): close the maintainer review of the convergence diagnosis Nineteen findings on the diagnosis and the ledger it reads. The ones that changed a judgement rather than a line: **The trend was measuring the wrong number.** Step 6 re-posts every unfixed ledger Critical under its original id, so the re-post floor only ever rises: a loop whose NEW findings collapsed from five to one still posts more comments than the round before, and a trend on the totals called that convergence "not falling" — permanently. The marker now records `fresh` beside `posted`, the trend runs on it, and a predecessor that recorded no fresh count leaves the trend unevaluable rather than measured on the wrong number. A carried id must also NAME a standing entry: models emit stray ids at the head of a claim line, and trusted on the token alone a genuinely new finding vanished from both signals. **The sort key inverted the premise of the advice it ranked.** The previous round's ledger is a POSTING set, so `priorRounds` deepens only where nothing is being fixed — and the paragraph then explained the top-ranked file as "a cluster that keeps producing siblings", about a file where no fix happened. It is also the key a stranger could set: one marker holding fifty legal ids on one file put a fabricated cluster in the top slot and evicted a genuine one. This round's new-finding count leads now. **Two readings, one branch.** The renderer discriminated on the clusters alone, so on the shape this feature exists for — recurrence and a flat trend together — the volume sentence and the entire floor recommendation were unreachable. Both are reported when both fire. **Trust seams.** `parseLedger`'s admission test is now shared with compose-review's side-file read, which restated two of its checks and skipped the rest; `dropped` counts what the filter rejected, so a shortened list no longer reads as complete and still certifies its anchor; the serializer re-validates an id after the length cap, which could cut a token mid-grammar; an unrecognised `k` is normalised rather than dropping the finding that carries it; an unknown identity is no longer read as "another account", which was stripping this account's own telemetry on a `gh` blip; foreign provenance is sticky while the work list can still carry foreign-minted ids, and records whether the list was MERGED over own entries, so the caveat stops over-claiming; and the union that protects own findings from a foreign winner now protects the own volume beside them. **Records that were false.** The convergence paragraph is returned on the result and printed as `CONVERGENCE:`, because the ladder sheds it first and the trim notice promised a terminal copy that did not exist; the floor is stamped only when the state named one, since `Ledger.floor` reserves absence for "not recorded"; and an absent floor folds to `auto` for what the round REPORTS while enforcement keeps its strict reading, so a posture the module had to guess at can still not move a finding out of the posting set. Also: the recurrence signal is held to round 3 like its sibling; the join matches a truncated ledger entry by prefix instead of truncating the drafted path, which was creating the prefix collisions it meant to avoid and posting a 200-character prefix as a real path; unmarked drafts are not counted as findings; `draftedFindingsOf` guards a non-array like its siblings; one shared projection replaces the hand-kept volume-group field lists at both persist seams; and the paragraph's REQUEST_CHANGES path — the verdict a diverging loop actually produces — is pinned. Twenty-two mutations, one per load-bearing decision, each verified to turn a named test red. * fix(review): close the bot's round 3 on the convergence diagnosis Four blockers, three of them introduced by the previous round's own fixes: - The marker's `fresh` count called `isFreshDraft` without the carried-id set while the paragraph ten lines away used the real one, so one body stated two volumes for one round — and the marker's undercount persisted as the next round's `prev.fresh`, where the trend's own guard reads it. The `EVERY_ID` default's premise was simply wrong: `convergence` is in scope at that call site. - The anonymous counter-advance branch hard-wrote `foreign: false` while keeping the work list verbatim, destroying a flag vouched under a known identity and making the sticky clause unable to ever re-fire. Both provenance flags now ride with `...kept`, like the list they describe. - The sticky `merged` term overrode a recovery that did not merge, so a pure-foreign winner inherited a claim that own-certified entries exist when every entry was a stranger's — the shape the union guard one function up refuses for the same reason. - `isLedgerFinding` bounded the id round only from above, so `R0-1` was admitted while `birthRound` rejects round 0 and `isFreshDraft` reads that rejection as "fresh": a re-posted `R0-*` counted as first-time work every round and narrated divergence at a settled steady state forever. Of the thirty-three suggestions, the ones that changed behaviour: - The side-file read counted only the marker's `dropped`, so entries its own admission test rejected shrank the work list while it still read as complete — the invariant this branch wrote into `parseLedger` two rounds ago, violated on the second read path. - Truncation qualifies BOTH readings, not just recurrence: the work list IS the carried-id set that defines freshness, so re-posts of shed entries read as first-time work and can manufacture the very trend that went undisclosed beside them. - The depth tiebreak was still a number a stranger sets, and ties are the ordinary shape — fifty planted ids on one file still evicted a genuine cluster. Depth is dropped entirely when the work list is foreign. - Carried ids are deduped the way `idFor` dedupes them, so a duplicated re-post is not read as carried here while the ledger mints it fresh. - `isLedgerFinding` gained the `LEDGER_MAX_ID` bound (admitted then sliced, an entry changes identity between rounds); `dropped` is clamped through the shared reader (it renders into the model-facing PARTIAL line and cannot be re-ruled); the anonymous seam drops `model` beside `sha`; the artifact validator carries `convergence` and `postedFresh`; and `pickVolume` makes the union's restore derive from the same list `withoutVolume` strips by. The rest were test gaps and comment drift from the previous round — a vacuous round-3 guard, a same-round comparison no test reached, a "terminal copy" test that never triggered the ladder, the `k` flag with no round-trip, and several comments still describing the design they replaced. All corrected. Fourteen mutations on the load-bearing changes, each verified to turn a named test red. * fix(review): close round 4 on the convergence diagnosis Three blockers, all on the write side of the ledger: - `serializeLedger` validated ids AFTER the length slice, and a cut can still match the grammar — `R3-` plus twenty-two nines slices to a well-formed twenty-four — so the marker carried a DIFFERENT id under the same entry. The next round's readback of the posted claim returns the full id, matches no ledger entry, and the finding retires with no ruling while the list reads as complete and the anchor still scopes past it. Admission now runs before anything is sliced, as it does on the parse side. - The `rejected` term added last round re-opened the unbounded-count hole the `declared` clamp beside it closes: `raw.findings.length` is attacker-chosen, and the sum is interpolated verbatim into the model-facing PARTIAL line. The SUM is clamped now, not one of its terms. - `idFor` kept a claimed carried id without checking it names a standing entry, so a model-emitted stray id was recorded under a fabricated mint round that the next round then CITED in a posted paragraph. Last round's fix corrected the counting side and left the recording side asymmetric. A claimed id absent from a COMPLETE work list is re-minted; over a shortened list, or with no recovered predecessor at all, it is kept — a non-member there may be an entry the byte budget shed, and continuity wins where the two cannot be told apart. Also: the own-volume restore no longer inherits the union's non-empty-list gate, so a clean own round's true-zero baseline survives a stranger's marker; the depth-key drop's `foreign`-only keying, the sticky `merged` clause's clear-on-empty, the volume group's survival through the ordinary recovered write, and the unknown-identity guard are each pinned; and the nine unasserted Chinese halves of the convergence paragraph now have assertions. One correction to a reply I posted last round: the round-3 volume-gate test was NOT fixed — the edit aborted on a failed pattern match and I reported it as landed. It is fixed here, and the mutation removing `input.round >= 3` now turns it red. Nine mutations, each verified to turn a named test red. * fix(review): close round 5 on the convergence diagnosis Four blockers, three of them asymmetries between two sides of a rule this branch already states: - The freshness determinations never received the work-list COMPLETENESS signal that `buildLedger` receives, so over a shortened list the marker kept a re-post's id (continuity wins) while the fresh count called the same comment first-time work. One marker said two things about one comment, and a loop doing no new work posted "the rate of new findings is not falling" every round. `isFreshDraft` now takes the flag and applies the same rule. A `findings` field that is not a list at all also stops reading as a COMPLETE empty list — it is a read that knows nothing, not a round that held nothing. - The floor-change guard was blind under the DEFAULT configuration: the marker recorded a posture only when the state NAMED one, while every consumer folds an absent floor to `auto` and resolves it determinately from the round and the context state. A real transition — round 6, or one transient context failure — left the guard nothing to compare and read as loop divergence, the misreading the field exists to prevent. The resolved posture is recorded now, from the same fold the advice and the enforcement backstop already use. (This reverses half of the round-3 fix, which took both alternatives that finding offered; only the fold was needed.) - The truncation caveat named the round undercount but dropped the overcount clause when no previous volume was cited — while the facts clause cites this round's fresh count unconditionally, and a shortened carried list inflates exactly that number. The overcount clause is unconditional now. - `buildLedger` stamped `line` under a looser guard than the admission test it feeds, so a model-written `12.5` made the serializer refuse the WHOLE entry: a posted finding retired unruled, the round was mislabelled budget-truncated, and the anchor was withheld. The line alone is dropped. Also closes the two bilingual parity gaps still standing from round 4 — the Chinese advice had no negative-direction assertion, and the already-at-floor branch's Chinese batching clause was pinned by no test on that branch. Seven mutations, each verified to turn a named test red. * fix(review): close round 6 — five blockers, all on rules this branch states - `isCarry`'s continuity keep admitted ids the serializer's own admission test refuses (over the length cap, round 0, a round ahead of this one). Kept, the entry is then refused WHOLE: a posted finding exits the work list owing no Step-6 ruling, the round is mislabelled budget-truncated, and the anchor is withheld. Continuity covers ids a shortened list may have shed; it cannot cover ids no list this pipeline wrote could hold. Re-minting costs the entry its cross-round id and nothing else — the same trade the integer-line guard makes. - The truncation caveat named the direction truncation mechanically DISABLES. The stray-id rescue is gated on the list being whole, so over a shortened one a genuinely new finding written under an earlier round's id cannot be rescued and reads as a re-post: the count is UNDERstated, not overstated. Both languages and the two comment blocks corrected. - An unrecognised (present, non-empty) `severityFloor` folded to `auto` in the reporting reading only, so the body claimed the round "already resolves to a critical posting floor" while its own deferral-licence clause said the floor carried no recognisable value and the enforcement backstop moved nothing. Only genuine absence folds now. - Restoring the own marker's volume onto a foreign winner re-paired own round-M counts with the winner's round N, so the paragraph attributed own numbers to a round this account never ran — "the previous round posted 0 (0 new)" beside a cluster citing a round that plainly did post. The restore applies only when the two markers describe the same round; absence already reads as "not recorded", which beats a wrong pairing. - The sticky `foreign` clause keyed on the NEW list's length, so one stranger's empty LGTM marker adopted before this account's first finding stamped a provably all-own work list foreign forever — and dropped the cluster sort's depth key over a list with zero fabrication risk. Both ends are required now: a list that could carry an id, and one that can still cite it. Six mutations, each verified to turn a named test red. * fix(review): close round 7 — two blockers on values this pipeline re-reads - `mdField` neutralised the code-span grammar and left the ledger marker's. The span makes Markdown and HTML inert to a RENDERER; this pipeline's own readers scan the raw body, and `stripLedgerMarker` takes the FIRST ``, deleting that round's prose AND its marker from the model-facing rendering. A complete forged pair additionally parses as the recovered ledger on any round the real marker is missing, which this account then trusts as its own. The delimiters are broken in the strip now. - The anonymous whole-write branch persisted the winner's volume verbatim under `foreign: false`. Without a `me` every marker walks as foreign, so the upstream strip never fires and `ownMax` is 0 — any marker inside the headroom wins. Kept, a stranger's counts became this loop's baseline: the trend evaluated against them, the paragraph cited them as own history, and they were stamped into this account's own next marker as `prevPosted`, which later recovery trusts. It takes the same "not recorded" degradation the counter-advance branch already accepts, through the same projection. Two mutations, each verified to turn a named test red. --- .../commands/review/compose-review.test.ts | 876 +++++++++++++++- .../cli/src/commands/review/compose-review.ts | 638 ++++++++++-- .../commands/review/lib/convergence.test.ts | 933 ++++++++++++++++++ .../src/commands/review/lib/convergence.ts | 640 ++++++++++++ .../src/commands/review/lib/ledger.test.ts | 249 +++++ .../cli/src/commands/review/lib/ledger.ts | 294 +++++- .../src/commands/review/lib/md-field.test.ts | 61 ++ .../cli/src/commands/review/lib/md-field.ts | 43 + .../review/pr-context-persist.test.ts | 368 ++++++- .../src/commands/review/pr-context.test.ts | 152 ++- .../cli/src/commands/review/pr-context.ts | 201 +++- packages/cli/src/commands/review/presubmit.ts | 8 +- .../src/commands/review/save-artifact.test.ts | 34 + .../cli/src/commands/review/save-artifact.ts | 37 +- 14 files changed, 4389 insertions(+), 145 deletions(-) create mode 100644 packages/cli/src/commands/review/lib/convergence.test.ts create mode 100644 packages/cli/src/commands/review/lib/convergence.ts create mode 100644 packages/cli/src/commands/review/lib/md-field.test.ts create mode 100644 packages/cli/src/commands/review/lib/md-field.ts diff --git a/packages/cli/src/commands/review/compose-review.test.ts b/packages/cli/src/commands/review/compose-review.test.ts index 2bd86ec8f1..6fcb3384eb 100644 --- a/packages/cli/src/commands/review/compose-review.test.ts +++ b/packages/cli/src/commands/review/compose-review.test.ts @@ -29,9 +29,11 @@ import { import { getGhHost, setGhHost } from './lib/gh.js'; import { BRIEFS } from './lib/agent-briefs.js'; import { + LEDGER_MAX_FILE, LEDGER_MAX_ROUND, LEDGER_MAX_VOLUME, parseLedger, + serializeLedger, } from './lib/ledger.js'; import { countInlineFindings } from './lib/inline-counts.js'; import { @@ -2665,6 +2667,55 @@ describe('composeReviewCommand handler (the CLI glue)', () => { expect(stderrHasOverride).toBe(false); }); + it('prints the convergence paragraph the trim notice points at', async () => { + // `noteTrimmedRanks` tells the author the shed sections "still hold — + // read them in the terminal report", and rank 0 is the first thing the + // ladder sheds.

Measured on PR #9342: the review posted at 11:56:34Z, review-pr failed at 12:00:53Z ("Qwen review completed but produced no output"), and the comment landed at 12:01:00Z saying the pipeline "failed before a review could be posted. … retry with @qwen-code /review" — a fresh ~3-hour review, asked for beside the review that had just landed. The autofix takeover loop reads the same feed a human does. Both sites now check, before composing a body, whether a review this run posted is already on the PR. The check is scoped three ways so a stale review can never buy silence on a genuinely dead pipeline: the bot's own account, the head this run reviewed, and a submission at or after this run started. Where the proof is unavailable — no start time, no head, a failed listing — the guard declines to fire and the comment posts, the same call the head-moved guard already makes. The job-level step now reads state and headRefOid in one `gh pr view` (the in-job step already did), which is where its head value comes from. Tests run the steps' real bash over review fixtures, because the guard IS a filter: silence when this run posted the review, and posting for each near-miss on its own — an earlier run's review at the same head, another account's, one of a different head, a PENDING one, none at all, an unavailable start time, and a failed reviews listing. One existing assertion tightened: "no `gh run view`" was the proxy for "no head comparison on comment runs", and the new guard asks that same command for startedAt on every event, so it now pins the head lookups themselves. The stub's state,headRefOid branch learned the pr_closed scenario its state-only sibling already knew. * fix(ci): anchor the already-posted guard on the run's creation, and say when it cannot run Round 1's two blockers, both re-verified against this repo's own run data. The time anchor reset on job re-runs. `gh run view --json startedAt` returns the LATEST attempt's start while the run id stays the same — the dedup above relies on that stability — so a re-run pushed attempt 1's review outside "this run": runs 32219268680 (created 05:23:57Z, startedAt 05:51:26Z) and 32218596441 (05:13:04Z → 05:22:05Z) both show the ~9-28 minute shift. Attempt 1 posts its review, the job fails after the post, someone re-runs it, attempt 2 fails before posting — and the guard, anchored on attempt 2's start, lets the contradictory comment through. Exactly the shape this PR exists to stop, on the path most likely to reach it. Both sites now anchor on `createdAt`, which is attempt-stable; a review submitted after the run was created still cannot belong to an earlier run, so the stale-review protection is unchanged. The guard also swallowed its own lookup failures. A transient failure in either call emptied the value, the guard declined, and the false comment posted with nothing in the log separating "the guard ran, nothing matched" from "the lookup died" — while every sibling lookup in these steps announces its failures. Both unavailable paths now emit a `::warning::` and a step-summary line before posting. No behavior change: posting was, and remains, the fail-open direction. Tests: a re-run fixture per site, where the stub answers `createdAt` and `startedAt` with DIFFERENT values and attempt 1's review sits between them — reverting either site to `startedAt` fails exactly these two; and a per-site assertion that both unavailable paths announce themselves. Also from round 1, both verified before taking: the stub's standalone `*state*)` branch is dead (no `--json state` call remains in either extracted step) and is removed, so its scenarios cannot be edited into a no-op; and the harness now substitutes `${{ vars.* }}` before running the in-job script, which bash rejected as a bad substitution — the assignment was skipped, `MAX_TIMEOUT_MINUTES` stayed unset, and eight error lines rode every suite run, so "the step's real bash" was not quite true for that line. * fix(ci): read the head this run reviewed, and claim only what the guard proved Round 2's six, all taken. The fallback JOB compared review commit ids against the PR's head at fallback time, not the head the run reviewed. On every trigger but pull_request_target the head-moved guard above deliberately does not run, so a push landing between the post and this step leaves that value pointing at bytes no review ever covered: the match fails and the contradictory comment posts anyway — the #9342 shape, re-opened for the trigger + post + push + fail-after-post interleaving. `review-pr` now publishes the head its review step recorded as a job output, and the guard reads it, falling back to the fresh head only when the job died before that step (a run that posted nothing either). The in-job twin needs none of this — its unconditional head-moved check exits first — and that asymmetry is now pinned per site rather than left to be rediscovered. Both skip messages claimed "this run already posted a review". Reviews carry no run id, so the window (bot account + head + submitted at or after this run was created) also matches an overlapping sibling run's review, which this workflow's own concurrency note says can happen. The suppression is right either way — a review IS sitting above the comment — but the oncall reading the summary was told something the guard never proved; both now say what it did. The guard's opening paragraphs still described the round-1 `startedAt` anchor while the code (and the paragraph below it, and the runtime warning) said creation. A maintainer reading top-down got the anchor that re-runs break — the defect round 1 removed. Test stub: `gh run view` now answers by running the caller's own --jq over an object carrying both timestamps, instead of a `case` on "$*" that matched substrings in order. A combined `--json createdAt,startedAt --jq '.startedAt'` was answered from the createdAt branch, leaving the re-run pin green for a guard reading the attempt-scoped field — the exact regression it exists to catch. * fix(ci): attribute the guard by time alone — the head is not a stable run attribute Round 3's blocker, and the second time the head clause re-opened the contradiction this PR exists to close. Two entrances this round, both after a "Re-run failed jobs": attempt 2 dies before the review step writes its head, so the guard falls back to a head attempt 1 never reviewed; or a push lands and attempt 2 records the NEW head — in both, attempt 1's own review no longer matches `.commit_id`, and the fallback posts "failed before a review could be posted … retry" beneath the review the same run had posted. Rather than patch the head lookup a third time, the head clause is gone. What the guard proves is now narrower and stable: a bot review of this PR was submitted while this run was alive — bot account plus the attempt-stable `createdAt` window. That closes both entrances at once and takes the round-2 cross-job wiring with it (review-pr's `expected_head_sha` output and the env line that read it), so there is no untested chain left whose silent breakage would restore the fresh-head comparison. The job-level step no longer needs the PR head either and reverts to its state-only query; the test stub's state-only branch, removed in round 1 as dead, has a caller again. The comment blocks now state the guarantee the concurrency model actually supports. They claimed a review inside the window "cannot belong to an earlier run", but per-run concurrency groups deliberately allow overlapping runs on the same head, so an earlier-created run's review can match and this run's failure then goes unannounced. That is accepted, and said plainly: the silence coincides with a bot review a reader can see — the very state that makes the comment's claim false — while the bot-author and creation-time clauses still rule out silence with no review at all. Tests: the moved-head case flips from "posts" to "silences" and is pinned per site (a review on ANY head inside the window silences); re-introducing a head clause fails exactly that test; and a structural pin asserts the wiring is absent rather than merely unused. * test(ci): skip the guard's jq-driven cases where jq is absent, instead of failing them The stub answers the guard's reviews and run-view lookups by running the caller's own `--jq` filter — that filter IS the thing under test — so those cases need jq on PATH. A reviewer running the suite on Windows without jq saw them as failures of the guard rather than as untested, which is the wrong signal in the wrong direction. Probed once per run and skipped honestly. Measured with a jq that exits 127: the file goes from 31 failures to 26 failures plus 13 skips — the 26 are the retry-loop cases, which have parsed the review log with jq since long before this change and are equally untestable without it. GitHub's windows-latest image ships jq, so CI coverage is unchanged either way; what changes is what a jq-less machine reports. * docs(ci): remove the head-keyed leftovers the guard no longer has Round 5's four, all leftovers of the round-3 design change rather than new behavior. The job-level block still explained why it compared against the head this run reviewed — naming `pr_head`, "the reviewed head's review" and a `review-pr` job output, none of which survive: the shipped filter is author scope plus the creation-time window, and the wiring was deleted with the head clause. A maintainer reading it would look for a comparison that is not there. The in-job block stated the createdAt-not-startedAt rationale twice, once with the measured run ids and once without; the measured one stays. Same in the tests: the stub's comment listed a head clause the filter deliberately does not have (`attributes by TIME, not by head` is the test that pins its absence), and the harness still declared and injected `reviewedHead`/`REVIEWED_HEAD_SHA`, which nothing reads since the wiring went — a knob that looks live and cannot be. * docs(ci): drop the duplicated anchor rationale and the last stale-head leftovers Co-authored-by: Qwen-Coder * fix(ci): exclude foreign same-account approvals from the already-posted guard * fix(ci): attribute the already-posted guard by composed-review markers The foreign-approval exclusion list shipped incomplete: the triage skill's commit-pinned APPROVE body also posts under the same account, matches the guard's author and window clauses, and silenced the fallback for a genuinely dead run — the failure shape this guard exists to stop. The producer set is open, so no exclusion list can be finished; every miss fails in the dangerous direction. Match positively instead: a review silences the fallback only if its body carries what only this pipeline's composed reviews carry — the "via Qwen Code /review" attribution footer or the invisible qwen-review-ledger marker. Every composed body carries at least one (a zero-findings APPROVE included); no foreign approval carries either. A marker that ever changes shape stops the guard firing and the comment posts — the pre-guard status quo, not a masked dead run. --------- Co-authored-by: qwen-code-ci-bot Co-authored-by: Qwen-Coder --- .github/workflows/qwen-code-pr-review.yml | 120 ++++++ scripts/tests/qwen-pr-review-workflow.test.js | 353 +++++++++++++++++- 2 files changed, 467 insertions(+), 6 deletions(-) diff --git a/.github/workflows/qwen-code-pr-review.yml b/.github/workflows/qwen-code-pr-review.yml index fd6f66c8d4..6b683dd379 100644 --- a/.github/workflows/qwen-code-pr-review.yml +++ b/.github/workflows/qwen-code-pr-review.yml @@ -1756,6 +1756,65 @@ jobs: echo "Fallback comment dedup lookup failed; deferring to the fallback-comment job." >> "$GITHUB_STEP_SUMMARY" exit 0 fi + # Same guard as the fallback-comment job's, for the same reason: a + # review posted moments before this step runs makes every body + # below — each one ending in a retry instruction — contradict the + # review already on the PR.

Observed as a Chrome renderer abort after multi-GB growth, reproducible on every reload of the affected session. - Release the replay snapshot once it is injected into the transcript store (SSE resumes from lastEventId; older history via pagination) - Rebuild replays under the configured maxBlocks cap and never raise the committed cap above it; trimming keeps the most recent blocks - Cap the debug text embedded for unrecognized session_update kinds, which appended one block per frame with the full payload - Pass the web-shell block cap to the subagent detail provider and lower the provider default window from 200k to 50k blocks * fix(review): address round-1 findings for transcript retention (#9303) Co-authored-by: Qwen-Coder * fix(review): cap debug payloads at the producer for transcript retention (#9303) * fix(web-shell): slim consumeReplaySnapshot to fit the SDK browser bundle budget The consume-and-drop API landed as a getter plus a private backing field, which pushed the minified browser daemon bundle 51 bytes past the assertBrowserSafeBundle budget. Collapse it to a single mutable replaySnapshot field swapped by consumeReplaySnapshot(), preserving the external behavior while fitting the budget without raising it. * fix(web-shell): bound transcript retention in bytes, not just blocks (#9303) Round-3 review fixes for the renderer OOM: - The capped diagnostic strings no longer retain their oversized parents: capped slices are detached via a UTF-8 round-trip before being kept on transcript blocks (capDetails and the 100KB text-block truncation), so a 4KB visible cap cannot pin a 100KB payload backing store. - Retention is now byte-aware: the transcript state keeps a running estimate of what blocks retain and trimming evicts oldest blocks until the estimate is back under a byte budget (128 MiB default), so the block-count window is no longer mistaken for a memory ceiling while tool blocks carry uncapped raw payloads. - The replay snapshot is released only after the injection dispatch succeeds, keeping the window consistent if normalization throws mid-injection. - The provider DEFAULT_MAX_BLOCKS is exported and guarded by a web-shell drift test instead of a duplicated literal. * fix(review): close round-4 byte-budget accounting gaps in transcript retention (#9303) * fix(webui): reject history pages that overflow the transcript byte budget (#9303) Pagination admission only checked the block cap, so a page could merge over the retention byte budget: idle sessions stayed over budget, and on live sessions the next trim evicted the freshly prepended oldest records, which the exclusive pagination anchor can never re-fetch — a permanent silent gap. Admit pages only when the merged estimate fits the budget, mirroring the atomic block-cap rejection. * fix(review): reconcile transcript eviction with the pagination anchor (#9303) * fix(webui): gate pagination re-open and drop stale in-flight pages (#9303) Round-7 review fixes for the eviction/pagination reconciliation: - The eviction re-open of the load-older affordance now applies the same gates as the sibling paths: it requires the session_transcript_pagination capability and an existing positional anchor (beforeRecordId or cursor). On non-pagination daemons or anchor-less sessions the capacity latch stays closed instead of exposing an affordance that would call a route the daemon does not serve and latch a pagination error. - A retention trim firing while a load-older page is in flight re-anchors the exclusive beforeRecordId; the stale page fetched against the old anchor is now dropped instead of merged, so it can never advance the anchor below the evicted band. Load-older fetches capture a monotonic pagination generation bumped on every block trim and drop the page when it moved mid-fetch (lossless: every record in the dropped page is older than the new anchor and is re-served by the next fetch). Adds regression tests for both: latch stays closed on live trims without pagination support, and an in-flight page is dropped across a mid-fetch re-anchor with the retry fetching against the re-anchored anchor. * fix(webui): gate pagination re-open on admission headroom (#9303) Round-8 review fix for the eviction-triggered capacity-latch re-open: - The re-open now checks whether the rejected page would actually be admitted against the post-trim window occupancy (carried on the truncation detail). A rejected page's footprint is remembered at rejection time; the latch re-opens only once enough count AND byte headroom has been freed for that page, stopping the streaming fetch/reject/re-render churn when count trims restore the window to exactly maxBlocks (zero headroom). - A footprint-less latch (replay saturation) re-opens only on real count headroom: while the count window is saturated, count admission rejects every page regardless of freed bytes. - A page that alone exceeds the whole retention window (block count or byte budget) can never be admitted in any occupancy state; it is now a terminal pagination failure (hasMore=false + paginationError) instead of a re-openable capacity state, so everything older than it is no longer silently unreachable. - Adds a maxRetainedBytes provider prop (mirrors maxBlocks) so the byte budget is configurable and testable; the replay rebuild store uses the same budget as the live store. Adds regression tests: churn suppression under count saturation, latch suppression while the freed hole is smaller than the rejected page, footprint-based re-open once eviction frees room (with re-anchored fetch), and terminal failure for a single oversized page. * fix(webui): reconcile pagination with eviction across rebuild and rewind (#9303) Round-9/10 review fixes for the retention/pagination reconciliation: - impossible is now evaluated across both admission dimensions with >= at the equality boundary: a page that alone fills the whole block window, or whose estimate alone reaches the byte budget, can never be admitted (an anchored window always retains at least one block / some bytes), so it routes to the terminal pagination failure regardless of which branch rejects first. - applyTranscriptHistory merges sentinel-aware: a pagination-resurrected real tool block mapping wins over the current window's TRIMMED sentinel for the same callId (the resurrected block is no longer orphaned), and the resurrected tool's trimmed-notification flag is cleared. - rewind (truncateTranscriptBeforeBlock) now fires the same 'blocks' truncation signal when it drops blocks, so freed capacity can re-open the pagination latch. The detail carries evictedOldest so consumers only re-anchor on oldest-first eviction (a rewind drops the newest blocks and leaves the oldest anchor intact). - The live-trim re-anchor clears a stale cursor atomically, and fails closed (clears the anchor, closes the affordance) when no retained block carries a recordId and the pre-trim replay had several distinct recordIds (a real evicted band) — with zero/one recordId the pre-trim anchor stays valid. - Replay-rebuild reconciliation runs for live-journal repair rebuilds too (both the ordinary and the marker-visible checkpoint-seeded branches observe trimming), and fails closed when the re-anchor is uncomputable with a real evicted band. - The rebuild affordance only opens with real admission headroom: a positional anchor and byte-budget room. Without byte-budget headroom (e.g. a single oversized block whose estimate alone exceeds the budget) no page can ever be admitted, so the affordance closes instead of burning on the first click. - projectChatRecordsToDaemonTranscript (offline/export projection) passes maxRetainedBytes: Infinity — its only documented truncation knob is maxBlocks; the live-window byte budget must not silently evict rendered or exported transcripts. Updates the affected pagination tests to non-boundary footprints and adds coverage for the eviction-direction signal. * fix(webui): harden eviction/pagination reconciliation corners (#9303) Round-11 review fixes: - Mirror the sentinel-aware merge for permissionBlockByRequestId: a page-resurrected real mapping wins over the current window's TRIMMED_PERMISSION sentinel, so a resurrected pending permission can flip to resolved (export isTrimmedPermissionBlockId next to the tool helper). - Snap retention eviction to record boundaries: one persisted record fans out into several blocks sharing a sourceRecordIds entry, and block-granular trimming could land mid-record, orphaning the evicted sibling blocks from exclusive-before pagination (the anchor re-sets to the shared record while the dedup filter drops any page still advertising it). Advance the cut until it no longer lands inside a record, keeping the at-least-one-block floor. - Content-aware dedup for recordId-less blocks: the locally echoed user prompt carries no recordId, so recordId dedup is blind to it; once a trim leaves it as the oldest retained block, a load-older page returning that prompt's persisted record would render it twice and double-count bytes. Drop page user blocks matching a displayed recordId-less prompt by text. - Fail closed when the rebuild trimmed and no retained block carries a recordId: with any pre-trim recordId, that record's blocks were all evicted and exclusive-before pagination never returns the anchor record itself, so anchoring there leaves it silently unreachable. Drop the anchor (affordance closes) instead of paging from a stale anchor. Updates the bounded full-snapshot fallback test to the fail-closed outcome. * fix(webui): close round-12 retention/pagination reconciliation criticals (#9303) Round-12 review fixes: - Scope the local-echo text dedup to the boundary pair (R12-1): the recordId-less echo can only collide with the page's newest user block, the one adjacent to the window's oldest block. Keying on text window-wide instead dropped distinct older prompts sent twice ("yes", a retry), permanently orphaning their assistant replies. Compare only the window's oldest recordId-less echo against the page's newest user block. - Gate observeReplayTrim on evictedOldest !== false (R12-2): a rewind also fires the 'blocks' truncation signal but drops the newest blocks and leaves the oldest pagination anchor valid, so it must not latch the capacity/re-anchor path during a capped rebuild (same gate the live store's onTruncation handler already uses). - Add the pagination generation guard to the loadMore catch block (R12-10): the success path already drops a page when a trim re-anchored mid-fetch, but the catch restored hasMore unconditionally, reviving the load-older affordance in the anchor-less state the fail-closed branch just closed. Leave the fail-closed state intact when the generation changed. - Back the record-boundary snap off the floor (R12-21): when byte pressure evicts to the last block, the forward snap's at-least-one-block floor stopped it from escaping a mid-record cut between the final two sibling blocks. Re-retain the penultimate block when the floor-pinned pair shares a record, trading at most one extra retained block against the budget to keep the record whole. Adds a reducer regression test. * fix(webui): close round-13 retention/pagination reconciliation criticals (#9303) Round-13 review fixes: - Count binary payloads in the retention estimate: Blob/File, ArrayBuffer, and typed-array/DataView values carry their content in non-enumerable slots, so the record walk only charged the fixed object overhead — an 8 MiB attachment counted as ~64 bytes and the byte budget never fired for media-heavy transcripts (the OOM class this PR targets). Charge Blob.size / byteLength for these shapes. Adds a budget-eviction regression test. - Loop the record-boundary floor back-off (R12-21 follow-up): the single back-off only re-retained one block, still cutting a 3+-sibling record mid-record. Loop while the boundary pair shares a record, keeping the record whole; the removeCount===0 guard retains the whole window when nothing is evictable. Grows the snap test to a 3-block record. - Offer the load-older affordance on a live trim for sessions that loaded unlatched: eviction re-anchored beforeRecordId but the re-open path only ran under capacityReached, so a session whose replay fit under the caps could never surface older persisted history after the window trimmed. Mirror the replay path's olderHistoryReachable gates in the re-anchor branch. - Key the boundary-echo dedup on echo presence and fold media into the comparison (R12-1 follow-up): an empty-text gate skipped image/file-only echoes entirely, and a naive empty-text match would collapse two distinct media-only prompts. Compare text + image/file counts for the boundary pair. * fix(webui): close round-14 retention/pagination reconciliation criticals (#9303) Round-14 review fixes: - Clamp the trim floor to keep at least one block (R14-1): a non-positive or non-finite maxBlocks made the count floor evict the whole window, and the record snap then read one past the end of the block array, throwing on every dispatch. Treat maxBlocks < 1 / non-finite as 1 so the window always keeps a block. Adds a regression test. - Drop the rebuild-trim fail-closed anchor unconditionally (R14-2): scanning only the fresh replayEvents missed recordIds trimmed from the repair checkpoint in a marker-visible live-journal repair, leaving a stale anchor with the affordance still on. Mirror the live store's fail-closed branch — when no retained block carries a recordId any pre-trim anchor is stale, and dropping an already-undefined anchor is a no-op. - Grow the latched rejectedPage footprint by a re-anchoring trim's evicted band (R14-3): the daemon re-serves the evicted band on the next exclusive-before fetch, so the page is larger than latched; a stale footprint would churn fetch/reject or misclassify a now-larger page as terminal. The re-open gate now measures the grown page. Reworks the re-open test to the faithful daemon behavior (the latch stays closed once the evicted band re-joins the page). - Refuse anchor-less forced retries (R14-4): after a fail-closed trim drops both cursor and beforeRecordId, a forced retry fetched with neither anchor, and the daemon defaults that to the journal's oldest page — prepended below the window and re-stamping a bogus anchor. Return early until a later trim re-establishes an anchor. * fix(sdk): integral-ize a fractional maxBlocks in the trim floor (#9303) Round-15 review fix (R15-1): the R14-1 degenerate-maxBlocks clamp floored non-positive and non-finite values to 1 but passed positive fractional values through unchanged, leaving removeCount fractional so the record-boundary snap indexed blocks[removeCount] one past the end and threw on later dispatches — the same crash class R14-1 was added to prevent, re-entering through a sibling input. Floor the clamped value so the window always trims by a whole block count. Math.floor is a no-op for the integer maxBlocks every in-repo caller passes. Extends the degenerate-maxBlocks regression test with a fractional case. --------- Co-authored-by: qwen-code-dev-bot Co-authored-by: Qwen-Coder Co-authored-by: qwen-code-dev-bot --- packages/sdk-typescript/scripts/build.js | 18 +- .../src/daemon/DaemonSessionClient.ts | 21 +- packages/sdk-typescript/src/daemon/index.ts | 4 + .../src/daemon/ui/chat-record-transcript.ts | 7 + .../sdk-typescript/src/daemon/ui/index.ts | 4 + .../src/daemon/ui/normalizer.ts | 29 +- .../sdk-typescript/src/daemon/ui/store.ts | 26 +- .../src/daemon/ui/toolPreview.ts | 5 +- .../src/daemon/ui/transcript.ts | 256 ++- .../sdk-typescript/src/daemon/ui/types.ts | 32 + .../sdk-typescript/src/daemon/ui/utils.ts | 22 + .../test/unit/DaemonSessionClient.test.ts | 31 + .../sdk-typescript/test/unit/daemonUi.test.ts | 577 +++++++ .../components/artifacts/SubagentDetail.tsx | 2 + .../client/constants/sessions.test.ts | 20 + .../web-shell/client/constants/sessions.ts | 15 +- packages/webui/src/daemon-react-sdk.ts | 7 + .../session/DaemonSessionProvider.test.tsx | 1429 ++++++++++++++++- .../daemon/session/DaemonSessionProvider.tsx | 579 ++++++- packages/webui/src/daemon/session/index.ts | 1 + packages/webui/src/daemon/session/types.ts | 8 + 21 files changed, 2990 insertions(+), 103 deletions(-) create mode 100644 packages/web-shell/client/constants/sessions.test.ts diff --git a/packages/sdk-typescript/scripts/build.js b/packages/sdk-typescript/scripts/build.js index 535c493205..c41d95ca80 100644 --- a/packages/sdk-typescript/scripts/build.js +++ b/packages/sdk-typescript/scripts/build.js @@ -93,13 +93,25 @@ const rootDir = join(__dirname, '..'); // Bumped from 195KB to 196KB for transient-vs-gone media hydration errors and // the reference-only replay placeholder. // Bumped from 196KB to 197KB for the workspace session live-state daemon -// surface (catalog version + live snapshot accessors) and immutable, -// identity-stable transcript block indexes used by browser renderers. +// surface (catalog version + live snapshot accessors), immutable, +// identity-stable transcript block indexes used by browser renderers, and the +// daemon transcript-retention work (replay-snapshot release + capped debug +// payloads, #9303) landing on top of the session media references bundle. // Bumped from 197KB to 198KB for the unrecognized-diagnostic sidechannel // (`unrecognizedDiagnostics` routing + selector, #8823). // Bumped from 198KB to 199KB for persistent session attachment read/remove and // binary resource hydration. -const MAX_DAEMON_BROWSER_BUNDLE_BYTES = 199 * 1024; +// Bumped from 199KB to 200KB for the retention byte budget (block byte +// estimation + budget-aware trimming) and backing-store-detached string caps +// (#9303 review round 3). +// Bumped from 200KB to 206KB for the pagination/eviction reconciliation and the +// #8823 × #9303 merge (#9303 review rounds 9-12): eviction-direction signal, +// rewind truncation callback, trimmed tool/permission sentinel helpers, +// record-boundary eviction snap, and the floor back-off — each bump budgeted +// its own delta in isolation, and the combined feature sets land here.
