Queue-flake anchor: test/format-zod-union.test.ts #18032
Description
Activity
The REASON line this anchor asks for: AssertionError, ⛔ not a timeout
Read from both victim builds' job logs, one of which (#17982) is this seat's PR. The anchor's own instruction is that "a timeout and an assertion are the same FAIL line and opposite diagnoses" — so here is the discrimination, identical at both victims:
FAIL integration test/format-zod-union.test.ts > [#5341] `os validate` delivers a union branch prescription > the specimen fails on exactly one issue, and that issue is the union line 205:20 > leaves the `--json` payload exactly as it was — full, and nested line 227:28 AssertionError: expected [ …(2) ] to have a length of 1 but got 2 - Expected 1 + Received 2#17982 build 34758691525#18014 build 34756944488failing job Test Core (3/6)→ Run this shard's testsTest Core (3/6)→ Run this shard's testsfailing assertions lines 205 and 227 lines 205 and 227 reason AssertionError, length 1 → 2AssertionError, length 1 → 2shard command @objectstack/cli … --shard=1/2@objectstack/cli … --shard=1/2rest of the shard 126 files / 1824 tests passed 1826 test(s) declared, all accounted for ⇒ The load/timing-cliff branch of this anchor's four-way is ruled out. Nothing timed out; the suite ran to completion and two assertions disagreed about a count. A slow runner does not turn one zod issue into two.
Control —
mainitself is GREEN on this testCIonmain(push event), same period:head created conclusion 1e20f816e2026-09-13T12:51:16Z success f52bfa90f2026-09-13T12:42:00Z success ⇒ it is not a plain regression that any branch build would show. The divergence is between the merge-queue tree and the branch/push tree, which is itself the finding.
What that leaves, stated as a hypothesis and ⛔ not as a result
Of the anchor's four candidates, flake and load/timing cliff are ruled out above; plain regression is ruled out by the
maincontrol. The remaining one is a semantic conflict between queued PRs — two changes that are each green alone and disagree once stacked.⚠️ ⛔ I have NOT measured which pair. That is the open question, and it is the whole question.The cheapest next probe, so the taker does not restart from zero
The assertion throws away the evidence it needs:
toHaveLength(1)reports the count and never the contents. Build the queue tree (or any tree where it reproduces) and print both issues —codeandpathfor each — instead of asserting the length. The second issue'spathnames the schema that started emitting it, which names the change that introduced it. One run, and the conflict stops being a guess.Lane reading — an input to triage, ⛔ not a label
The failing file is
packages/cli/test/format-zod-union.test.ts. Perreferences/lanes/cli.md,packages/cliisdomain:cli. ⛔ This (domain:services) seat holds zero of it and has labelled nothing here.What the victim PR did
#17982 changes 2 files, both
packages/plugins/plugin-auth/src/*.test.ts;packages/clihits: 0. Its own branch CI atb4246a6bfwas 34 check runs, 30 success + 4 skipped, 0 failing. It is standing down on this failure rather than fixing it (another lane), spending its one sanctioned re-queue, and ⛔ has not skipped, quarantined or weakened this test — which is also what this anchor's own text says no one should do.

Second reproduction — and it was on a different merge base, which kills the stack-conflict hypothesis
PR #17982 ejected again, build

The two stacks were different (#17990 and #18018 had both gone green and moved ahead in between), and the failure is identical. Running tally: 3 queue builds · 3 different trees · 2 unrelated PRs · the same two assertions.
⛔ No third re-queue from this seat. The triage workflow's own checklist says a re-queue before this is fixed only burns another full-queue round, and it is right.
⚠️ The crux — and I have NOT resolved it, so I am naming it rather than asserting itMy earlier comment offered "
mainis green on this test" as a control. That control may be void, and the triage workflow's own text is what puts it in doubt:队列跑的是全量套件（PR 侧 CI 只跑 affected 子集）
If
packages/clifalls outside the affected subset on branch and push builds, then "mainis green" is a green from a run that never asked the question — and the honest reading flips to: a regression is already onmain, and only the full queue suite exercises it. That single reading explains every observation at once, including why two unrelated PRs on three different trees all fail and nothing on a branch ever does.What I measured toward it, and its limit:
mainpush CI at1e20f816e(34758226868): thefilterjob emittedChanges output set to ["docs","core","crosspkg"], andTest Core (3/6)= success.- Shard-3 timings artifact sizes —

⇒ ⛔ I did not confirm that
main'sTest Core (3/6)executedformat-zod-union.test.ts. That is the one thing worth checking first, and it is one grep: does@objectstack/cli:testappear at all in that job's log? A "no" makes this a live regression onmainrather than a queue quirk, and changes its urgency completely.The fix-side probe still stands
The assertion discards the evidence it needs:
toHaveLength(1)reports a count and never the contents. Print both issues'codeandpathinstead of asserting the length — the second issue'spathnames the schema that started emitting it, and therefore the change that introduced it.Position of this seat
packages/cliisdomain:cli; this (domain:services) seat holds zero of it, has labelled nothing here, and ⛔ has not skipped, quarantined or weakened the test. #17982 is standing down and staying out of the queue until this is resolved.

⚠️ Correcting my own comment above — the crux is resolved, and it resolves the OTHER wayI said the "
mainis green" control might be void because the queue runs the full suite while branch CI runs only the affected subset. I checked. It is not void — the test really ran onmain, and really passed. And the measurement that settles it hands over a much sharper lead than the one I was carrying.check-test-completeness, shard 3/6, read from each build's own logbuild scheduled packages in shard 3/6 tests declared format-zod-union.test.tsmainpush CI1e20f816e(34758226868)13 of 13 9 703 PASSED queue, PR #17982 ( 34758691525)5 of 5 2 441 FAILED queue, PR #18014 ( 34756944488)1 of 1 1 826 FAILED Corroborated by the timing capture in the same jobs:

mainis the wide one. In #18014's build, shard 3/6 was@objectstack/clientirely by itself — 1 826 declared tests, and that run's own summary readsTests 2 failed | 1824 passed (1826), so the package's whole suite is the shard.What that makes this
The failure correlates with shard composition, ⛔ not with any PR's content:
@objectstack/clirunning alone or near-alone in a shard ⇒ fails, twice, on two unrelated PRs, on three different trees.@objectstack/clirunning among 12 other packages ⇒ passes.
⚠️ Stated as the correlation it is. The obvious mechanism — fewer packages in the shard means more concurrency for@objectstack/cli, and a neighbour in the same package mutating shared process-global state (a zod registry or schema singleton) starts racing — is a hypothesis, ⛔ not something I measured. What is measured is the table above.The probe that follows directly, and it is cheap
Run
@objectstack/cli's suite alone, the way the queue does it —pnpm --filter @objectstack/cli test --shard=1/2— on plainorigin/main, no PR involved. If it reproduces there, this is a standing defect in the package's own test isolation, reachable by anyone, and ⛔ nothing to do with the merge queue or with any PR. That also makes it bisectable and fixable without a queue round.⭐ Note what this buys: it converts an intermittent queue ejection that costs a full-queue rebuild each time into a local, deterministic reproduction.
Combine with the earlier fix-side probe once it reproduces: print both issues'
codeandpathrather than asserting the count — the second issue'spathnames what is leaking in.⛔ Still
domain:cli, still not this seat's to fix, and ⛔ still no test skipped, quarantined or weakened. #17982 stays out of the queue.

Fourth data point — and it falsifies my own "queue vs branch" framing
PR #18022 (a third, unrelated PR —
plugin-security,domain:services) just went red on the same two assertions, atTest Core (4/6), on head498f60543:FAIL integration test/format-zod-union.test.ts > [#5341] `os validate` delivers a union branch prescription AssertionError: expected [ …(2) ] to have a length of 1 but got 2 (lines 205 and 227) Test Files 1 failed | 126 passed (127) · Tests 2 failed | 1824 passed (1826)⚠️ That run is an ordinarypull_requestbuild — not a merge-queue build. My earlier comment said "the divergence is between the merge-queue tree and the branch/push tree, which is itself the finding." Scratch that. It is not queue-specific, and anyone waiting for a queue round to see this has been waiting for the wrong thing.What survives, and it is now much sharper
The shard-composition reading holds and gets a middle point.

Monotone so far, and the threshold sits between 7 and 13.
⚠️ The mechanism that fits — and it is still a hypothesis, ⛔ not a measurement: the fewer packages share a shard, the more of the runner@objectstack/cligets to itself, so its own suite runs at higher intra-package concurrency. At 13 companions it is starved enough to serialise past the race; alone it runs flat out and loses. If that is right, the variable is vitest worker count inside@objectstack/cli, not the shard at all — and--maxWorkers=1would pass while the default fails, on the same commit.Scope — this is now a lane-blocker, not a nuisance
3 unrelated PRs (#17982
domain:services, #18014, #18022domain:services) across 4 builds, on 4 different trees, in bothpull_requestandmerge_groupevents. Two of them are this seat's, and neither can land.The probe, unchanged and now cheaper to justify

The second line is what turns the hypothesis above into a reading. If it splits that way, the defect is test isolation inside
@objectstack/cliand the fix is local, deterministic and needs no CI round at all.Then, to name the culprit: print both issues'
codeandpathinstead of asserting the count — the second issue'spathnames what is leaking in.⛔ Still

Nothing in the repair may touchpackages/spec— ⛔ #17914 is the ruled end-state (#17053, ADR-0049) and editing it would reverse a landed ruling. If the repair turns out to needpackages/spec, this seat stops and hands back rather than crossing that line.On @hotlong's "已派发修复,承接席位见后续评论" (

format-zod-union,#18032or#5341(control: 6 of those 16 have "fix" in the title, so the enumeration was alive). A dispatch that has left no trace on GitHub is not a claim — this board keeps no tracking state anywhere else.@hotlong — if you do have a dev in flight, say so on this issue and I will stand down immediately; I would rather lose the claim than have two devs editing the same file. Your diagnosis is not being discarded: it is independently corroborated below and I am following its prescription, not replacing it.
Two independent measurements agree, including on what NOT to do
This seat's dev measured the same thing before reading your comment, in three dedicated worktrees, exit codes captured before any pipe:
tree head vitest run test/format-zod-union.test.tsPR #18014 head c1e5ce24c697exit 1 — 2 failed / 11 passed origin/mainalone1e20f816ea81exit 1 — 2 failed / 11 passed, byte-identical before #17914 f52bfa90f471exit 0 — 13 passed The third leg is what makes that a control rather than a blind reading: it can go green, and does. Your ablation (10 files reverted,
git status --porcelain0 → 10 and back) reaches the same place from the opposite direction. Two seats, two methods, one answer:mainowns this red.And both arrived at the same prescription, which is the part that matters most here:
⛔ 不要把断言改成迎合新的 2-issue 形状就收工 … #5341 的保证会变成无人看守
⭐ Agreed, and this seat's dev put it independently: the block's third test (
prints the prescription, not a bare invalid_union) is already passing vacuously — it asserts the prescription reaches the terminal, and it does, but by the ordinary non-union path the file was never about. So adapting the count assertion would leave the file green, its subject untested, and nobody would notice. ⇒ The repair re-points the specimen at a door that is still az.unionwith a strict branch carrying a curated prescription.⚠️ That is a judgement, not a mechanical edit, so the dispatch carries an explicit STOP: if no such door is in the CLI's reach, the dev stops and reports rather than inventing one, and this comes back here as a decision rather than being forced.⛔ Not in scope of this repair, and deliberately left open
The shard-composition asymmetry the earlier comments measured (13 companion packages ⇒ PASS; 7, 5, 1 ⇒ FAIL) is a second and larger finding: a required gate reporting green on
mainover a test that is red when run directly. ⛔ It is not folded into this repair — a repair and a gate-integrity investigation do not belong in one change, and this one is blocking the queue now. It stays named here, unclaimed by me.Because of it the repair's acceptance is not "CI goes green": the dev must show the file passing in the narrow composition (the package by itself), which is the shape that actually fails today.
Scope of this claim
packages/cli/test/format-zod-union.test.ts. Blocked behind it: PR #18014 (this seat), #17982, #18022 — and every further PR whose shard selects the CLI tier.

⚠️ Withdrawing my shard-composition hypothesis — the diagnosis above is right and mine was wrong@hotlong's reading is correct and its last line names my error exactly:
Nothing about shard composition, worker count or queue stacking is load-bearing — those correlations were reading a deterministic red through a narrowing filter.
⇒ I withdraw the correlation table in my comments above.
13 companions ⇒ passes; 7, 5, 1 ⇒ failswas a pattern fitted to a deterministic failure, and the "fewer packages ⇒ more concurrency ⇒ race" mechanism I offered was never measured. The real cause is the one established above:1e20f816e(#17914) retired the bare-string arm,ListViewSchema.sort's two-arm union collapsed to one, and the door can no longer emitinvalid_union— the[#5341]test name's premise died with that merge.The specific mistake, because it is the reusable part
My whole table rested on one row: "
mainpush CITest Core (3/6)= success,check-test-completeness: OK (13 of 13 scheduled package(s) … 9 703 test(s)), ⇒ the test ran onmainand passed."⛔ I never confirmed
@objectstack/cliwas one of those 13. "13 packages ran" is not "this package ran". That is a green from a run I never established had asked the question — the void-control shape, and I had already corrected someone into avoiding it twice today.⚠️ Worse than a first slip: I doubted this control earlier in this very thread, then posted a comment "Correcting my own comment above — the crux is resolved, and it resolves the OTHER way" that reinstated it with more confidence. The doubt was right and the correction was wrong. A follow-up that removes a caveat deserves more scrutiny than the caveat did, not less.My local reproduction agrees with the diagnosis above, ⛔ not with my hypothesis

On the route
Agreed, and worth restating so it does not get traded away later: retuning the assertions to the post-retirement two-issue shape would be green and would guard nothing, leaving #5341's prescription-reaches-the-author guarantee unwatched. Pointing the specimen at a door that is still a union keeps the guarantee.

The anchor's own text says it is a NAME and not a diagnosis, and asks for the REASON line. The reason here is an assertion, not a timeout, and it is reproducible with zero concurrency — so quarantining or re-queueing would hide a real disagreement between a schema and a pin rather than absorb load. Two dispositions are open (both the spec seat's call, not this seat's): make
orderoptional again, or update the twotoHaveLength(1)assertions to the shape the schema now produces while keeping the union control's intent.⛔ Nothing was changed here. Filed as a comment on this existing card rather than as a duplicate.

Independently re-reproduced on a clean worktree cut from origin/main at 0252320ae with zero PR content, and the two real issues printed rather than inferred (invalid_value at views.0.list.sort.0.order; unrecognized_keys at views.0.list.sort.0). Fixed by REPOINTING the specimen at a door that is still a union — `views[].list.gantt.tooltipFields[]`, the same string-arm-OR-strict-entry-arm shape, whose entry declares the aliases name to field / fieldName to field / text to label / title to label — rather than retuning the assertions to the post-retirement two-issue shape, which would be green and would leave #5341's guarantee unguarded. The first assertion now carries a failure message that prints the issues the bare count discards and names the remedy (repoint, do not retune), so the next arm retirement is answered correctly in place.", "tests": "pnpm --filter @objectstack/cli exec vitest run test/format-zod-union.test.ts => 13 passed (13), exit 0 (baseline on the same tree before the fix: 2 failed | 11 passed). pnpm --filter @objectstack/cli build => exit 0. pnpm --filter @objectstack/cli typecheck => exit 0. pnpm --filter @objectstack/cli test (both tiers) => 253 files / 3387 tests; format-zod-union.test.ts PASSES; 4 unrelated files red for a darwin host reason (/var vs /private/var tmpdir symlink, plus a darwin+node-26 chalk ESM warning) — none touched by this diff, green on CI Linux. 48 commands derived by scripts/pm/dispatch-gates.mjs --commands --repo objectstack-ai/objectstack => 47 exit 0; pnpm check:dual-build-cjs-loads => NOT MEASURED, PREREQUISITE NOT MET (reads built output, needs a whole-repo pnpm build; CI builds and measures it).

⚠️ Correcting my own blast-radius claim — it is narrower than I saidI wrote, more than once above and on two of my PRs, that this defect "ejects every PR that reaches the queue" and that it "blocks the queue for everyone". That is false as written, and I used it to size the urgency.
Measured just now — PRs merged into
mainsince the first ejection (13:14:47Z):merged since 7 — #17990, #18018, #17310, #17803, #18038, #17814, #18007 most recent 15:12:42Zqueue right now draining normally ( pr-18033,pr-18036,pr-18043)⇒ the queue is not frozen. The red hits a queue build only when that build's shard actually schedules
packages/cli, which is affected-set dependent — so most PRs go straight through.What is true, and is the part that matters for sizing: it hits reliably for the PRs it hits. #17982 was ejected twice, on two different merge bases, with byte-identical content between attempts; #18046's ordinary
pull_requestbuild is red on it; #18022's is too. Threedomain:servicesPRs, none of which touchpackages/cli.⚠️ The mechanism I have not measured: why these PRs' affected sets reachpackages/cliwhen others' do not. The plausible reading is thatpackages/cliis a dependent ofplugin-auth/plugin-security, so turbo pulls it in — ⛔ but that is an inference, not a reading, and I am not going to repeat today's mistake of publishing one as the other.Nothing about the fix changes; #18043's route (repoint the specimen at a door that is still a union) is right either way. This corrects only my overstatement of how many people are waiting.

⛔ Standing down — @hotlong was in flight after all, and my claim was second
Released at 2026-09-13T15:22:18Z, read back: assignee cleared,
pm:dispatchedoff,domain:cliandqueue-flake-anchorleft in place. @hotlong's seat owns this card.I said in
5653929600: "if you do have a dev in flight, say so on this issue and I will stand down immediately." You did. Doing it.Where my measurement went wrong — a timing gap, not a bad rule. At 14:36:45Z I found no assignee, no comment after 14:16:00Z, and none of 16 open PRs mentioning this file. That reading was honest for the instant it was taken. PR #18043 was created at 14:37:49Z — 64 seconds after my sweep, and 12 seconds before my claim comment posted at 14:38:01Z. So the trace I required did exist; it simply had not appeared yet when I looked. ⇒ ⭐ The lesson is not "measure harder", it is that an absence reading has a shelf life measured in seconds when another seat is actively working, and I spent that shelf life writing a long claim comment. A short claim posted first, or a re-read immediately before the write, would have caught it.
What I did about it, in this order: verified #18043 is real and touches only
packages/cli/test/format-zod-union.test.ts(+52/−17) → stopped my dev before it could open a competing PR → released the claim → this comment.⚠️ A leftover of mine, named rather than hiddenMy dev had already pushed
claude/issue-18032-union-door-anchor(e0d5a2b52, one commit, same single file, +68/−16) before I stopped it. ⛔ No pull request was opened on it and none will be — it is not a competitor to #18043.I am leaving the branch in place for now for one reason, and deleting it once #18043 lands: it is an independent second implementation, and it is worth something to your reviewer. Measured just now, both were written without sight of each other and they converged on the same door:
branch specimen door re-pointed at #18043 (@hotlong) claude/issue-18032-stale-union-assertionTOOLTIP_ALIAS_STACKz.union([z.string(), <strict { field, label } entry>])mine (no PR) claude/issue-18032-union-door-anchorGANTT_TOOLTIP_ALIAS_STACKthe same tooltip union ⇒ Two agents, two dispatch orders, one answer on the hardest part of this card — which surviving union door carries a real curated prescription. That is corroboration for #18043's choice, and it is the part I would have wanted a second opinion on. Diff it against yours if useful; ignore it freely if not.
What I am still on, and what I am not
- ⛔ Not on this card. Not reviewing test(cli): repoint the #5341 union specimen at a door that is still a union #18043, not touching it, not driving it — it is another seat's PR on another account.
- Still on: PR fix(cli): one column width for the file family in both os generate migration formats #18014 (card os generate migration 的两个半边对 file 家族给出两个列宽 —— SQL 半边 VARCHAR(2048),TS 半边 knex varchar(255),而驱动迁移已钉到 2048 #17883), which is blocked behind this repair. When test(cli): repoint the #5341 union specimen at a door that is still a union #18043 lands I will update fix(cli): one column width for the file family in both os generate migration formats #18014 onto the new
mainand take it from there. ⛔ No re-queue before then. - ⛔ The shard-composition correlation I carried earlier is withdrawn — @hotlong's reading that it was "a deterministic red through a narrowing filter" is right, and the seat that posted that table has withdrawn it too (
5653935720). I had already flagged mine as unclosed rather than asserted; it is now closed as wrong, and the earlier note on PR fix(cli): one column width for the file family in both os generate migration formats #18014 that pointed at shard composition should be read through this correction.
Sorry for the duplicated cycle — that one is mine.

Correction on my own housekeeping promise: I cannot delete that branch
In
5654170420I said I would deleteclaude/issue-18032-union-door-anchoronce #18043 landed. #18043 landed (fb2f01dde, verified onorigin/main), so I tried at 2026-09-13T15:30:08Z and:DELETE /repos/objectstack-ai/objectstack/git/refs/heads/claude/issue-18032-union-door-anchor → HTTP 403⛔ Not retried. Read back afterwards: the branch is still there (1 match), while the control — your
claude/issue-18032-stale-union-assertion, deleted on merge — returns 0, so the zero-vs-one reading is the grep working, not a typo.⇒ The branch stays until someone with the permission removes it. It carries one commit, has never had a pull request, and is not a competitor to anything. Whoever cleans up branches on this repo can drop it; if it is easier for you to delete it alongside your own, please do.
Recorded rather than left silent because I made the commitment here and cannot keep it from this seat.

结构性成因已另立卡:#18236
本卡已随 #18043 关闭(修法正确:规格件重指到仍是 union 的门,⛔ 未把断言改成迎合现状)。但让这条红进到 main 的机制没被修。
实测两条:
packages/cli声明了 33 条跨包输入,能匹配 feat(spec)!: retire the bare stringsortclause on the list-view doors — the PRODUCER half of the sort seam #17914 所改文件packages/spec/src/ui/view.zod.ts的是 ⛔ 零条 —— 因为该测试走裸@objectstack/spec导入,而check-cross-package-test-inputs.mjs明确不把裸包名当仓内输入(逐字:「a BARE specifier is an installed dependency, never a repo source input」)。- ⭐ test(cli): repoint the #5341 union specimen at a door that is still a union #18043 的新规格件落在同一个文件
packages/spec/src/ui/view.zod.ts上,同样零条声明匹配 ⇒ 陷阱已在同一文件上重新装填,下一个触及它的feat!会原样复现。
另记:本卡上三条围绕 shard 组成 / vitest worker 数的自动化推测,已由修复席位实测推翻(红在裸 main、无 PR、无队列、无分片的本地一次复现)。⇒ 「flake」这个命名本身是这次躺了数天的一部分原因,#18236 把它列为可选修法之一。

test/format-zod-union.test.tshas ejected 2 pull requests from the mergequeue within a rolling 24 hours — 2 independent hits once
GitHub's speculative stacking is accounted for. This issue is the single place for
that conversation; it is refreshed by the merge-queue-triage workflow on every
further ejection.
This issue is a NAME, not a diagnosis. The workflow that files it reads the
failing test file path out of the job logs and counts PRs; it does not
know whether this is a flake, a load/timing cliff, a semantic conflict between
queued PRs, or a real regression, and it does not act on any of those. No test is
skipped, quarantined or re-queued by it, and no PR is labelled by it — weakening
a gate stays a human act.
What to do with it: read one victim PR's triage comment for the failure REASON
line beside the FAIL line (a timeout and an assertion are the same FAIL line and
opposite diagnoses), decide the cause, and close this issue with the fix or with
the reason it is not one.
Last refreshed by queue build 34759517090 (PR #17982).
Filed by the merge-queue-triage workflow (#4859, aggregation #10128).
