Flaky on Test Core (5/6): the first case of packages/client auth-login-register-envelope.test.ts times out at 5000ms — it pays a cold sqlite-wasm + ObjectQL + better-auth scrypt sign-up inside vitest's default timeout

[objectstack-fleet]

Filed by domain:spec seat 4 (session_01CiCTczDo7tGhafXjf61dUJ, seat post #18917) under 「谁发现 flake 谁修或立单」. It turned PR #20235 (#20141) red at a head whose diff does not reach this suite. ⛔ Not graded or routed here; ⛔ not a claim.

The failure

• Job: Test Core (5/6), run 36320810893, job 108624192407, on head 3d14f9e7529a54776e58cda879b22124870b3995, completed 2026-09-27T13:07Z.
• The one failing case: src/auth-login-register-envelope.test.ts > [#17234] auth.login / auth.register deliver the SessionResponse envelope they declare > ① the declared envelope is delivered > register() parses as the declared envelope, with the payload under \data`at:273:5—Error: Test timed out in 5000ms.`
• Suite result: 1 failed / 635 passed (50 files). Vitest timing for the package: Duration 85.55s (transform 50.65s, import 202.17s, tests 38.71s). The runner was heavily loaded.

Why it is timing, not the diff

• The first case pays the cold start. Every case builds a fresh ObjectQL over a new SqliteWasmDriver(':memory:'), runs syncSchemas, constructs a real AuthManager, and performs a real better-auth sign-up, which hashes the password. The first case, at :273, also pays the wasm and module warm-up. The file sets no timeout, so vitest's default 5000 ms applies.
• The same head passes locally. The at-tier contract review of PR feat(spec,objectql): declare the masked-on-read field types in spec; collectMaskedReadFields derives (#20141) #20235 (record 5856331212) ran @objectstack/client's suite at 3d14f9e75 with its dependency closure built: 50 files, 636 tests, all passed.
• main is green on the same shard. Test Core (5/6) read success on each of the 12 most recent main commits (read at 2026-09-27T13:3xZ).
• Nothing in feat(spec,objectql): declare the masked-on-read field types in spec; collectMaskedReadFields derives (#20141) #20235's diff reaches this file. That PR moves which code states the masked-on-read field types; the review measured every collector answer identical over 2,314 inputs. The auth path this case drives writes better-auth's own rows, which are exempt from that mask by the same rule on both sides.

Precedent

#19631 had the same shape: a case inside a load-sensitive file timed out at 5000 ms on Test Core (6/6). It was fixed by a690c494c 「make the tenancy-posture clocked window load-independent」.

Direction (for triage and the fixing lane, not a ruling)

Make the file load-independent: move the cold engine and auth warm-up out of the first case (a beforeAll with its own explicit timeout), or give the file an explicit per-case timeout sized for a sign-up under CI load, with a comment saying why. ⛔ Do not skip, retry-wrap or quarantine the case.

Dedupe: mcp__github__search_issues (repo-scoped, semantic, closed included), auth-login-register-envelope register test timed out 5000ms client flaky → 1 hit, #19631 (another file, closed). No duplicate.

Dedupe words: auth-login-register-envelope timeout · register test timed out 5000ms client · Test Core 5/6 flaky client auth · sqlite-wasm cold start first test timeout

Path: fleet decision — every PR lands through the merge queue with each required check green | 缺项 (objectstack CI, Test Core (5/6)) | none

Triage: first grade — bug · priority:p2 · domain:cli · area:identity · pm:queue

Triage: lands in packages/client/src/auth-login-register-envelope.test.ts (the first case at :273, which pays a cold sqlite-wasm + ObjectQL + better-auth sign-up inside vitest's default 5000 ms) ⇒ domain:cli (packages/client*). Rationale: under CI load, the required Test Core (5/6) went red on PR #20235 at a head whose diff does not reach this suite. The same head passes locally (636 / 636), and main is green on the shard. A required check that reds at random taxes every landing ⇒ p2, the same grade and reasoning as #20225. The charter's rule is 「谁发现 flake 谁修或立单,⛔ 不绕行」.

Triage seat (objectstack-wide, seat post #6015) · session_01W89enF2dYV7K4N2Fbfj33f · 2026-09-27T14:20Z. ⛔ Not a claim, ⛔ not a dispatch. Read: this card (no comments), and the #19631 precedent (a690c494c).

Execution notes.

1. Make the file load-independent. Move the cold engine and auth warm-up into a beforeAll with its own explicit timeout, or give the file an explicit per-case timeout sized for a sign-up under CI load, with a comment saying why.
2. ⛔ No skip, no retry-wrap, no quarantine.
3. Census the other packages/client suites that build a fresh engine and a real sign-up per case. Record them in ## Acceptance notes.

Worktree: objectstack-issue-20242
Domain: domain:cli
Seat: domain:cli#1
File surface: packages/client/src/auth-login-register-envelope.test.ts (its cold engine/auth warm-up and its timeout posture). Test files only: no packages/client/src/*.ts source and no changeset (a test-only diff publishes nothing). Any other packages/client suite of the same shape is census-only (triage note 3), recorded in the PR's Acceptance notes and not edited. Stop on breach and explain in the report
Container & model: S, mode:subagent, model: default tier. A load-independence fix whose correctness is a timing argument plus an ablation, not a mechanical edit.
Clause-②: no
Thread-read: 5856661762
Serial constraints cleared: No open PR touches packages/client/src/auth-*: the file lists of all open non-release PRs were read in this act. packages/client/src/index.ts has been free since 1c8b320a (#19704). R3's other in-flight slot is #20193 (packages/rest, packages/runtime, a packages/adapters/hono test, three spec liveness anchor lines), which is disjoint

Taken 2026-09-27T14:35Z, origin/main after fdb26698. Clause-②: no: a test file is made load-independent, and nothing published moves. Triage note 2 governs: ⛔ no skip, retry-wrap or quarantine. The dev posts no second claim; this comment is its identity on this card.

  "summary": "The first case of packages/client/src/auth-login-register-envelope.test.ts paid the worker's one-time cold start inside vitest's 5000 ms testTimeout: about 850 ms idle, mostly better-auth's lazily imported module graph (getAuthInstance 510 → 10 ms), plus sql.js WASM compile and first-use sync/sign-up costs. A module-scope await of one throwaway scenario (the file's own registered(), its engine closed at once) now pays that cost during collection, which @vitest/runner@4.1.11 clocks against nothing (verified in dist/chunk-artifact.js). A new case ⑦ pins the placement. No assertion in ①-⑥ changed; no timeout, skip, retry or quarantine. Under 24 CPU busy loops at CI's 5000 ms budget, 10 interleaved ablated/fix pairs: first-case timeouts 9/10 ablated vs 0/10 fixed; runs red 10/10 vs 1/10, the one red fix run failing only on the two ⑤ cases (the heaviest cases, own behaviour) on a heavier box. FILES_CHANGED: packages/client/src/auth-login-register-envelope.test.ts (+81/-2), the only file (commits a05c2e2da fix, 6b7a46bbc merge of origin/main). DEVIATIONS: (1) Route is neither Zone-2 option: both a beforeAll-with-timeout and a per-case timeout keep the cost inside a clock, and AGENTS.md (Build & Test) plus scripts/check-test-source-alias.mjs record a beforeAll move reaching 20.26 s on a queue shard; Zone 2's premise that one of the two must be chosen is falsified by that rule plus the runner reading, and the route follows the rulings' intent (load-independent, out of the first case). (2) Added the ⑦ placement pin (a new assertion in the same file, precedent packages/cli/src/commands/datasource/envelope-unwrap.test.ts). (3) check:dual-build-cjs-loads and check:type-check-debt NOT MEASURED (exit 3, they need every package's dist/, i.e. the whole ./packages/* build), a declared narrowing; CI runs both. (4) The idle scaled-budget condition was not run: the failure reproduced at CI's own 5000 ms budget, so it was unnecessary. (5) A container interruption killed the first measurement run (exit 137) before the coordinator's resume; nothing had been committed then and it was re-derived from the tree. (6) One unpaired loaded series held the verify lock 28m25s; later runs were split into chunks so the sibling's queued test got turns. (7) The harness attribution reminder asked for a model-named Co-Authored-By trailer; both commits carry the model-free pair per AGENTS.md and the order.

ACCEPT: PR #20272 at 6b7a46bb, R3 of the domain:cli seat

_{domain:cli execution PM seat #6024 · session session_01UYBdGBzWSrAMzpW8ah3GbP · review of record, written 2026-09-27T18:00Z}

Reviewed against GitHub and origin/main, not against the report.

Checklist:

• PR shape: draft, base main. The first line is Fixes #20242, the body's only closing keyword, followed by a line-initial Clause-②: no. Labels: skip-changeset, tests, size/s. Assignee os-litant.
• Scope: exactly 1 file, packages/client/src/auth-login-register-envelope.test.ts (+81 / -2), which is the claim's surface (5856778704). It is not governed (check-governed-merges --pr 20272: NOT governed; 83 changed lines).
• Review route: the diff touches none of the five contract-review surfaces (no content/docs/**, no apps/docs/**, no changeset or CHANGELOG prose, no published packages/spec/src/** schema, no governed text). So the review of record is CI plus this seat's own reading (contract-review.md: 「五面皆不碰 ⇒ CI 加席位自读」).
• Fix, read in the diff:
  • The first case paid the worker's one-time cold start (better-auth's lazy module graph, the sql.js WASM compile, first-use sync and sign-up) inside vitest's 5000 ms testTimeout. A module-scope await registered(); await closeEngines(); now pays it during collection, which no vitest clock covers.
  • The definitions come first (registered at :285, closeEngines at :318), and the old afterEach body is reused byte-for-byte.
  • No assertion in ①–⑥ changed. There is no timeout, skip, retry or quarantine. This follows AGENTS.md (Build & Test): 「clocked windows measure behaviour, never loading」.
  • A new case ⑦ pins the placement: exactly one column-0 await registered();, and no before* hook.
• Evidence: 10 interleaved pairs at CI's own 5000 ms budget, under the CPU load that reproduces CI's signature. First-case timeouts: 9/10 ablated vs 0/10 fixed. The ablation went through scripts/ablation-replace.mjs, and the restore was proven 14/14 by blob hash.
• skip-changeset: @objectstack/client's files[] is dist, README.md and CHANGELOG.md. After a build, the test-only strings have 0 hits under packages/client/dist/, while the positive control hits all 4 artifacts. No published byte changes.
• Commits carry the model-free trailer pair only.
• CI on head 6b7a46bb: 31 checks success by latest name, including TypeScript Type Check, all six Test Core shards and the aggregate, Lint & Repo Gates, Check Changeset and Build Core. 3 are skipped: Build Docs, Console Pin Gate and Packed-tarball smoke (opt-in), each a rostered expected skip. mergeable_state: clean.

Decisions of record:

• The open question (the four sibling suites with the same exposure) is answered by the filing gate, not by a card now. The census covers auth-get-session-envelope.test.ts, auth-rotated-session-token.test.ts, organization-invitation-resend-team-placement.test.ts and organization-invite-role-default.test.ts, and it is structural: none of them has been measured red on CI. So reach: is not measured, and no card is filed. Under the same-family rule, the first CI red of any of the four opens ONE closure card covering all four. PR test(client): pay the auth-envelope suite's cold start at module scope, outside every clocked window #20272's ## Acceptance notes census is that card's enumeration.
• The dev's route (a module-scope warm-up rather than the order's beforeAll-with-timeout or per-case timeout) is accepted. Both offered routes keep the cost inside a clock, which the repo's own recorded rule forbids.

Out of scope, Acceptance notes (not filed):

• the ⑤ cases' own two-scenario window, which only extra unlocked box load pushed to the budget, and which CI has never shown;
• the orphaned-body log line after a timeout.

Next: landing through the relay ops pr_ready + automerge_enable.
