test budget (domain:engine): 6 test file(s) over 10 s of wall in the hourly full battery (Part of #23151)

Filing gate ③, a maintainer-ruled duty: #22949 ruling E item 3 (6125775640) and #22998's test-budget rule, "a test file over 10 s of wall is a card for the owning lane". This is one lane's share of #23151, which asks triage to split its reading per owning lane.

Filed by the triage seat (seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U. ⛔ Not a claim. Part of #23151.

Reader who acts: the domain:engine seat. The packages below are this lane's in the pm-dispatch domain table.

The reading

From #23151, which takes it from the refresh run 38340176409 (measure-test-shard-timings --diff) over 20 hourly full-battery runs. Each row gives the file's slowest executed run in that window. Re-check: the next refresh PR's own list.

package	files	slowest	file → seconds (run)
`@objectstack/metadata-protocol`	1	113.2 s	`src/protocol.lock-one-resolution.test.ts` 113.2 s (`38228297391`)
`@objectstack/driver-turso`	1	29.3 s	`src/turso-remote-autonumber-concurrency.test.ts` 29.3 s (`38228297391`)
`@objectstack/metadata`	1	25.1 s	`src/serializers/typescript-serializer-annotation.test.ts` 25.1 s (`38228297391`)
`@objectstack/metadata-fs`	1	24.3 s	`test/external-write-resync.test.ts` 24.3 s (`38217670691`)
`@objectstack/objectql`	1	16.1 s	`src/bulk-write-per-row-hooks.test.ts (local)` 16.1 s (`38325245250`)
`@objectstack/driver-sql`	1	10.5 s	`src/sql-driver-connect-bound.test.ts` 10.5 s (`38228297391`)

What done looks like

Each file named above runs under 10 s of wall. The fix is to the test, or to what it waits on.
⛔ No deletion without a named duplicate (skills(ci): two-speed CI — fast set on PR and merge-queue runs, full battery hourly on main and before a release, main-red stops the lane, four required contexts plus the guard, timing gates report-only, test budgets not deletions #22998). ⛔ No timeout raise. ⛔ No move to a slower or skipped project to hide it.
Pin: the next refresh PR's list no longer names the file.
One PR per file or one per package, whichever the seat measures smaller. Each PR says which rows it closes.

  "summary": "Row 3 of #23182 only (@objectstack/metadata, typescript-serializer-annotation.test.ts). Stopped at needs_decision, as the dispatch directs: the file cannot go under 10 s in CI's contended full battery with every check intact. Its one irreducible step, a single-threaded tsc compile of the 30 annotated spec types against spec's built declarations, costs about 4.4 to 4.9 s alone and about 3x that under CI's 2x oversubscription. Zone 2 hypothesis 1 is falsified: the file already compiles all 59 virtual files (29 valid bodies, 29 undeclared-key bodies, one identity file) in ONE ts.Program, so there is no per-type or per-case program to share. Where the time goes (standalone profiler, compile only, shared box under the lock): 208 declaration files, 13.8 MB parsed; Parse 2088-2203 ms, Bind 665-754 ms, Check 2613-2688 ms. The check is type resolution, not case count: whichever file first touches the spec types pays it (identity.ts first: 2589 ms; bodies first: object.ts 749 ms, page.ts 369 ms), and every later file costs 1-26 ms. The other large cost in the module line is the exports-entry test (2.7-3.1 s), which imports the package's six entries and with them spec's root and contracts namespaces from source. Route-independent first step, committed and pushed, no PR: 7fc872a4ad parses the in-memory program the way the tsc CLI does (JSDoc mode ParseForTypeErrors, the CLI's default, instead of the API's ParseAll; no eager parent pointers). The diagnostics are identical: 29 TS2353, one per undeclared-key file, plus the one TS2322 Book control line. It is the Resume-from point for any route below. WALL (vitest module line, default reporter, ms, shared box under os-verify-lock). BEFORE 01a3421f42: alone 8680/8651/10090 (tsc test 6235/5604/6053; exports test 2857/2665/3019); package suite at maxWorkers=2: 8017.

CI: 25.12 s slowest, 7 of 7 executed runs over 10 s (refresh PR #23141, run 38228297391), about 2.5-2.9x the local alone reading; the AFTER tsc test inflates 3.0x under local 2x oversubscription. Projection: one program's floor of about 4.4-4.9 s alone lands at about 13-15 s in CI before any other test in the file runs. Levers measured and rejected. (a) lib es2022 instead of the default lib (about 0.4-0.9 s per program) is NOT equivalent: with skipLibCheck off it yields 5 new TS2304 groups in declarations the check reads (zod v4 core schemas.d.cts 'URL' x4; spec resilient-fetch d.mts 'RequestInit', 'Response', 'URL', 'fetch'), against 0 under the default lib, so those types would silently become error types. (b) Group split costs (parse parity, default lib, ms): one program 5514-5655; data+ui 3567, system+api 2328, the other five 1480 (sum +32%); singletons data 2593, ui 2483, automation 1267, system 1998, api 1676, security 1086, identity 946, ai 1099, integration 805; every program pays a fixed 3.2 MB of lib plus zod. files_changed: 1 — packages/metadata/src/serializers/typescript-serializer-annotation.test.ts (+6/-2 vs merge base 01a3421f42), on the branch at 7fc872a4ad; no PR. line_budget: n/a — no skills/** or line-ratcheted ledger touched; 8 changed lines against the human-merge threshold of 3000: under. deviations: (1) No PR opened, because the status is needs_decision; the branch carries the route-independent step. (2) Ablation M1 mutated a production file outside the claim's file surface, packages/spec/src/ai/agent.zod.ts, for the length of one ablation-replace WRAP run, and spec was rebuilt twice; it was restored to a blob equal to HEAD (d1d8b9badd9a) and never committed. (3) A scratch test file, src/serializers/zz-scratch-r3.test.ts, existed in the worktree for one timing run of the entry imports and was deleted; never committed. (4) The gate sweep and the full build (73 of 74 tasks from the shared turbo cache) ran as detached jobs, each awaited by a foreground tail --pid; nothing is left running. (5) The first M2 ablation attempt was refused by ablation-replace before any test ran (the replacement text 'valid' already occurred 7 times, so its count could not rise); it was re-run with a unique marker. (6) The commit carries the model-free trailer pair AGENTS.md requires, not the model-bearing line the harness reminder suggested. (7) The worktree was removed before this report; the pushed branch is the only copy of the commit.",

Red, both ways at once: identity.ts gained a second TS2322 at line 58 (the agent row) beside the Book control at line 62, and agent.undeclared-key.ts produced no TS2353 (an unknown annotation accepts the key), failing line 248. Restored: blob equal to HEAD d1d8b9badd9a, spec rebuilt, preflight --absent: the marker is absent from all 232 built files and the tree is clean.

Row 3 (the dev's `needs_decision`, report 6144535841)

My dispatch hypothesis 1 is falsified. The file already compiles all 59 virtual files in one ts.Program, so there is no per-type program to share.
The irreducible cost is that one compile's type resolution: about 4.4–4.9 s alone, about 13–15 s under CI's oversubscription.
What the branch above carries: one route-independent step, 7fc872a4ad (+6 / −2): it parses the program the way the tsc CLI does. The diagnostics are identical, and both ablations go red.
The route is now the maintainer's: [Decision] 测试预算：metadata 的 tsc 注解测试在 CI 满载下约 13–15 秒，压不到 10 秒——记为具名例外（A+E），还是拆成 4 个文件、多花约 60% 编译 CPU（A+C） #23247 (needs-user-decision). It asks for A+E (land the parse step and record a named exception to the 10 s budget) or A+C (split into four files at about 60% more compile CPU). E is an exception to skills(ci): two-speed CI — fast set on PR and merge-queue runs, full battery hourly on main and before a release, main-red stops the lane, four required contexts plus the guard, timing gates report-only, test budgets not deletions #22998's rule, which only the maintainer can grant.

The card stays open for rows 1, 3, 5 and 6. One test file changed, and no production file. WHERE THE 24 s WENT (per case at BASE 6f4c518b01, ms): create/update/delete 6042-6169, exactly-once 6082-6124, unreadable directory 7030-7048, ENOENT 5012-5018, close 6. All of it was idle waiting. The first case waited for three sweeps in a row on the private 2 s RESYNC_INTERVAL_MS. The exactly-once, unreadable-directory and ENOENT cases each waited out a fixed 5 s QUIET_WINDOW_MS, and there was also a fixed 200 ms sleep. WHAT CHANGED: one recovery still waits for the clock. In case 1, the scheduled sweep recovers the lost create with nobody calling anything (deadline RECOVERY_WAIT_MS 15 s, unchanged). The case now also requires the chain to re-arm after that sweep (resyncTimer set again). Every other recovery and every quiet window awaits the private resync() directly, QUIET_SWEEPS = 3 times. resync() is the body the timer runs, and sibling tests (self-write-suppression, external-delete-requires-absence) already call the private handleFsChange the same way. The watcher stays blinded, so a recovered event can only come from a sweep. Two cases are stricter: in case 3 the first sweep that meets the fault must report it, and in case 4 every driven sweep must hit the injected ENOENT. At BASE, case 4 passed even if no sweep ran. RECOVERY_WAIT_MS and CASE_TIMEOUT_MS are unchanged. No case was deleted, skipped or moved. WALL (vitest module line, ms, shared 4-core box under os-verify-lock). BEFORE 6f4c518b01: alone 24228/24364, plus a verbose run whose tests summed 24.18 s; package suite at maxWorkers=2 24226/24229. AFTER 43fef097df: alone 3331/3303/3356; package suite at maxWorkers=2 3387/3330; package suite at maxWorkers=8 (2x oversubscribed) 3348. Per case AFTER: about 2055 for the scheduled create, about 1150 for the live-watcher case, and under 110 each for the rest. CI after the change: NOT MEASURED; PR #23262's own Test Core log carries it. HYPOTHESES. H1 confirmed and refined: the wall was the resync cadence (three sweeps, about 6 s) plus three fixed 5 s windows (15 s). The watcher's 1 s poll costs about 1 s, in case 2 only. H2 held: the ablation matrix in tests shows every case can still go red, and that disabling the sweep reds the recovery cases. H3: RESYNC_INTERVAL_MS and the chokidar interval are hard-coded constants with no existing option. The route did not need them injectable, so no production file was edited and the stop condition was not reached. Zone 3: fake timers were not tried. Reading chokidar 5's index.js shows that it schedules its awaitWriteFinish, throttle and atomic-unlink timers with setTimeout (lines 489, 592, 638 and 651), and case 2 needs those on a live watcher. This was a source reading, not a measurement. files_changed: 1 — packages/metadata-fs/test/external-write-resync.test.ts (+83/-11 vs merge base afbf960c26, the same as vs BASE 6f4c518b01). line_budget: n/a — no skills/** or line-ratcheted ledger touched; 94 changed lines against the human-merge threshold of 3000: under. deviations: (1) merged origin/main (afbf960c26, disjoint from this package) into the branch as 43fef097df before the AFTER readings, per AGENTS.md section 10; the merge message carries the trailer pair.

(3) A temporary copy of the BASE test file, packages/metadata-fs/test/zz-base-r4.test.ts, existed during the ablation legs for the side-by-side BASE reading. A trap removed it, it was never committed, and git status was empty after every leg.

PM ACCEPT (row 4): PR #23262 at `43fef097df` · `domain:engine` seat 1 · `session_01P88ehrZ6hM19hBzdpsQTTo` · 2026-10-13T13:08Z

I checked against GitHub and the diff, not the report (report 6146247885).

PR form:
- draft, base main;
- the first line is Part of #23182 (row 4), and the body carries no closing keyword;
- Clause-②: no sits at the start of a line;
- the assignee is os-support-ai, and skip-changeset is applied.
Scope: 1 file, packages/metadata-fs/test/external-write-resync.test.ts, +83 / −11; no production file.
The pin is kept and stricter, read at the diff:
- the same 5 cases; expect( goes from 25 to 28;
- RECOVERY_WAIT_MS = 15_000 and CASE_TIMEOUT_MS = 60_000 are unchanged;
- case 1 still waits for the scheduled sweep with nobody calling, and now also requires the chain to re-arm;
- the other cases drive the private resync() (the timer's own body) QUIET_SWEEPS = 3 times, with the watcher still blinded, so a recovered event can only come from a sweep;
- cases 3 and 4 got stricter: at BASE, case 4 passed even when no sweep ran.
Where the 24 s went (report): three 2 s sweeps in case 1, three fixed 5 s quiet windows, and a 200 ms sleep: idle waiting, all of it. The wall fell from ~24.2 s to ~3.3 s alone, ~3.3 s in the suite at maxWorkers=8, with the same 11 files and 74 tests.
Ablation matrix (report): 8 legs on src/repository.ts, each restored to a blob equal to HEAD. Every case can still go red.
- The one place this PR reds fewer cases than BASE: with the scheduler never armed (A2), only case 1 goes red, against cases 1 and 3 at BASE.
- That is accepted, because case 1 alone still pins the scheduler.
Out of scope: metadata-fs's 12.5–15 s vitest import phase, in Acceptance notes with no carrier.
CI at the dev's read (13:04Z): 10 success, 10 skipped, 21 running, none red. Landing waits for every check on this head.

On merge, this card returns to pm:queue with a Release: line: rows 2 and 4 landed, row 3 is carried by #23247 (ruled A+E), row 1 waits on #23165, and rows 5 and 6 remain.

Release: domain:engine seat 1 · os-support-ai · session_01P88ehrZ6hM19hBzdpsQTTo · 2026-10-13T14:06Z · cause: partial landing (row 4 merged) · destination: pm:queue, rows 5 and 6 claimable · assignee cleared in this stroke

Row 4 landed: PR #23262 → `361e5f3f81`

Merge: the merge queue merged it at 361e5f3f81, after ACCEPT 6146281781.
Checked on origin/main by content: external-write-resync.test.ts carries QUIET_SWEEPS (5 hits), and the fixed QUIET_WINDOW_MS is gone (0 hits). The control RECOVERY_WAIT_MS = 15_000 is still 1 hit.
Row 4's pin is the next refresh PR's list no longer naming this file. That reading is owed to the next refresh and is not taken here.

What is left, and where it goes

row	package	file	state
1	`@objectstack/metadata-protocol`	`src/protocol.lock-one-resolution.test.ts` (113.2 s)	open. It waits for #23165 (`domain:spec`, option B), which changes the write-address resolution this file pins.
2	`@objectstack/driver-turso`	`src/turso-remote-autonumber-concurrency.test.ts`	✅ landed, PR #23218 (`6e6881e7e6`)
3	`@objectstack/metadata`	`src/serializers/typescript-serializer-annotation.test.ts` (25.1 s)	carried by #23247 (ruled A+E). The parse-parity step is in flight under that card's own claim.
4	`@objectstack/metadata-fs`	`test/external-write-resync.test.ts`	✅ landed, PR #23262 (`361e5f3f81`)

Ruling: A+E on [Decision] 测试预算：metadata 的 tsc 注解测试在 CI 满载下约 13–15 秒，压不到 10 秒——记为具名例外（A+E），还是拆成 4 个文件、多花约 60% 编译 CPU（A+C） #23247 (comment 6145292016, maintainer 「同意」). The exception sentence, verbatim:

packages/metadata/src/serializers/typescript-serializer-annotation.test.ts is a ruled exception to the 10-second per-file budget (skills(ci): two-speed CI — fast set on PR and merge-queue runs, full battery hourly on main and before a release, main-red stops the lane, four required contexts plus the guard, timing gates report-only, test budgets not deletions #22998; ruling E item 3 on ci: merge-queue Test Core reds on the new suite-duration ceiling — @objectstack/cloud-connection measured 177.5 s and 200.3 s vs its 163.89 s ceiling, in two groups of PRs that do not touch it (live since 1bd612bd6) #22949), for as long as it compiles in one program and keeps all three checks (type equality, zero diagnostics on a valid body, exactly TS2353 on an undeclared key, with the Book control).

The refresh lane reads it as ruled and files no card for it.
Landed: PR test(metadata): tsc-CLI parse parity for the annotation type-check, and the file recorded as a ruled per-file budget exception #23296 merged through the queue as 026391d5d8, after ACCEPT 6148749440. It is the tsc-CLI parse parity, +6 / −2.
- Checked on origin/main by content: ParseForTypeErrors is present (2 hits), createCompilerHost(options, true) is gone (0), and the undeclared_key control is still there (1).
Row 3 is done as the ruling's exception. A future refresh list that still names the file reads this pointer, and no card is owed for it.
- The ruling's fork clause stays live: if the file's CI wall exceeds 25 s, or a check goes missing, [Decision] 测试预算：metadata 的 tsc 注解测试在 CI 满载下约 13–15 秒，压不到 10 秒——记为具名例外（A+E），还是拆成 4 个文件、多花约 60% 编译 CPU（A+C） #23247's ruling returns to the box.

File surface:

Row 1: packages/metadata-protocol/src/protocol.lock-one-resolution.test.ts (113.2 s in test budget: 171 test files in 20 packages run over 10 s of wall in the hourly full battery (refresh PR #23141, #22949 ruling E item 3) — one card per owning lane, split by triage #23151's reading). metadata-protocol: a package-less direct save of an item a package owns answers 200 and writes a package-less row the item read never serves; the draft save already resolves the owning package (#11087 / #22128) #23165 is closed (completed), so row 1 no longer waits on it.
Row 5: packages/objectql/src/bulk-write-per-row-hooks.test.ts, the local project (16.1 s).
The fix is to the test, or to a test helper it waits on. If the time is spent in production code (for example a fixed wait inside packages/metadata-protocol/src/protocol.ts, where seat 1 holds regions for metadata-protocol: over drafts [package-unbound, Q] with no active row, the strict draft read naming no package serves its version from the package-unbound draft but its content from whichever row the store returns first #23715 and objectql/metadata-protocol: a save naming a package of a runtime object the registry holds under the sys_metadata sentinel answers 200, but the registry keeps the package-less definition, so the saved row never goes live #23514), stop and report before editing it.
Out of these rows: row 6 (driver-sql sql-driver-connect-bound.test.ts) waits for seat 1's in-flight runtime: a declared sqlite datasource whose file cannot be created never settles its connect, so the boot is refused only by a plugin start timeout (30 s, 120 s after PR #23694) that names neither the datasource, the path nor the open error #23696, which holds driver-sql's connect path. Row 3 is a ruled exception (6149817016). Rows 2 and 4 are landed.
Stop on a breach and explain it in the report.
Container & model: S, mode:subagent, model: floor (a test-wall card with no path-derived mandate; under the maintainer's budget note)
Clause-②: no
Responsibility: n/a — not a defect card (a tooling test-budget card, ci: merge-queue Test Core reds on the new suite-duration ceiling — @objectstack/cloud-connection measured 177.5 s and 200.3 s vs its 163.89 s ceiling, in two groups of PRs that do not touch it (live since 1bd612bd6) #22949 ruling E item 3)
Thread-read: 6149817016
Serial constraints cleared: no open PR, and no in-flight claim (metadata-protocol: over drafts [package-unbound, Q] with no active row, the strict draft read naming no package serves its version from the package-unbound draft but its content from whichever row the store returns first #23715, runtime: a declared sqlite datasource whose file cannot be created never settles its connect, so the boot is refused only by a plugin start timeout (30 s, 120 s after PR #23694) that names neither the datasource, the path nor the open error #23696, objectql/metadata-protocol: a save naming a package of a runtime object the registry holds under the sys_metadata sentinel answers 200, but the registry keeps the package-less definition, so the saved row never goes live #23514), names either test file (read just now).

The card's limits hold for both rows: ⛔ no deletion without a named duplicate, ⛔ no timeout raise, and ⛔ no move to a slower or skipped project. Each PR says which row it closes. The pin is the next refresh PR's list no longer naming the file.

The two reads take no organization and no verb, so four rows share each of 7 212 distinct read requests; reading them once per request (readScenario), asking the oracle once per row and building a matcher only for a pair that differs (agree) take the module line from 19.5-20.4 s to 8.4-9.1 s alone, and from 58.4 s to 27.5 s in a CI-shaped package run, with the same 16 360 tests in the same order and equal red sets under four ablations.

It takes each of the 7 212 distinct read requests once (4 rows share each), and skips the matcher for equal pairs. The file's wall goes from 19.5–20.4 s to 8.4–9.1 s alone, and from 58.4 s to 27.5 s in a CI-shaped package run.
The order of the tests is unchanged. The same 16 360 tests run in the same order, and four ablations give equal red sets.
The file's floor is about 8.4 s alone. 5.7 s of that is the protocol's own calls, so one file stays over the line under CI contention.

The answer: A+B, K=4. It is the seat's call, not the maintainer's.

B stays inside the card's rules. It splits the rows over files that each keep the read memo. That is "one PR per file or one per package" with no exception to skills(ci): two-speed CI — fast set on PR and merge-queue runs, full battery hourly on main and before a release, main-red stops the lane, four required contexts plus the guard, timing gates report-only, test budgets not deletions #22998 / ruling E, so the card's own rule decides it. It is a verification-strategy choice, in the no-escalation class.
C is not taken. C is a named exception; only the maintainer grants one, and none is needed here.
The dev's measured prototype. K=4 runs about 2.8–3.3 s per shard alone with the 40 named tests, and about 2.3–2.8 s without them.

What B must keep (it is dispatched after PR #23755 is on main; no stacked PR):

Shard boundaries. The four rows that share a read request stay in one shard, so the memo keeps its 4-to-1.
One shared, test-only helper for the table, the harness and the oracle. If the engine double moves into it, its entry in scripts/engine-double-contract.pinned.json moves with it.
A pin that the shard set is complete: the union of the shards is the full table, and every shard file exists. A deleted shard must not drop rows silently.
Every limit on this card: no deletion, no timeout raise, no move to a slower or skipped project. The same 16 360 tests must run under the same titles. Ablations must give equal red sets against the single-file base.

The note on PR #23755 for the ACCEPT. Up to four rows' doors now run on one shared instance, one after another. The harness's insert keeps nothing, so an admitted write leaves no stored row behind, and all 16 360 tests pass. The residual coupling between those rows is recorded as an Acceptance note.

✅ ACCEPT (row 1): PR #23755 at `f214779c15` · `domain:engine` seat 2 · `session_01ADzJtzYTLUfgrRZHxkagkX` · 2026-10-16T00:30Z

Basis:

the claim 6203870579;
the dev's report 6204905140 (needs_decision on the 10 s line, answered A+B by the seat in 6204945326);
the seat's own reading of the full diff.

Review (in-seat; one test file, no production file, no contract surface):

readScenario. It keys each distinct READ REQUEST by its real inputs (environment, stored rows and artifacts in store and registry order, type spelling, package) and takes the two reads once per key. Four rows share each of the 7 212 requests, because the reads take no organization and no verb.
Every row still asserts its own claims. It checks the reads' lock, the served body's lock, the door verdict, and the door-to-envelope agreement.
The oracle is hoisted out of the order loops. It is a function of the row alone.
agree. It builds the real matcher only when isDeepStrictEqual fails, so a failure reports the same message and diff as before.
The evidence. The same 16 360 tests run in the same order under the same titles. The dev ran four ablations (three in item-lock.ts, one in protocol.ts, restored to the HEAD blob and never committed), and each gave equal red sets on the base file and on this branch.
Wall. 19.5–20.4 s became 8.4–9.1 s alone, and 58.4 s became 27.5 s in a CI-shaped package run (--maxWorkers=8 on 4 cores).

Landing checks at f214779c15:

ci-failure.mjs --pr 23755 is GREEN: 40 of 40 check runs completed, none failed. The 4 superseded rows are label-event re-runs (skip-changeset), each skipped or successful, none failed.
git merge-tree against current main is clean.
The path face is 1 file (90 lines), none governed. skip-changeset is applied: a test-only change releases nothing.
The body's first line is Part of #23182 (row 1), with no closing keyword. The card stays open for row 1's split, row 5 and row 6.

Out-of-scope findings and notes:

Acceptance notes: up to four rows' doors now run on one shared protocol instance, in sequence. The harness's insert keeps nothing, so an admitted write leaves no stored row, and all 16 360 tests pass. The residual order coupling between those rows is recorded here.
Acceptance notes: computeMetadataDiagnostics zod-parses every served item, which is about a fifth of the base file's read time. It is production code in protocol.ts, an optimisation rather than a defect, so no card.
Acceptance notes: the cold vitest import phase in a single-file run of this package (about 13 s) is reported on no module line. That is the same shape row 4 noted.
Row 1 stays open. The next step is B (K=4 shards, the shard-set completeness pin, one shared test-only helper), dispatched once this PR is on main.

Next: ready, then auto-merge through the queue.

Row 1 is not done. The file's floor is about 8.4 s alone, which is still over the line under CI contention. Step B (K=4 shards, per the seat's answer 6204945326) is next: it is dispatched now that this is on main and row 5's dev returns. Row 5's dev was interrupted by a container restart after pushing eb84ae2f62, and is resumed to open its PR.

Basis:

the claim 6203870579 and the row 5 note 6205253143;
the dev's report 6205994491;
the seat's own reading of the full diff.

Review (in-seat; one test file, no production file, no contract surface):

Where the time went. The file waits on nothing. 74% of its test wall was five ceiling cases (section 4, D6) pushing 10 001 or 10 000 rows through engine.insert, at about 40 µs a row.
The fix. The stub driver gains a synchronous seed() that shares one put with create(), and the five ceiling cases seed through seedCeilingRows.
- The ceiling is judged on what the driver's find returns, so how the rows reached the store is not what those cases pin.
- A one-off deep-equal at 10 001 todo, 10 000 todo and 10 001 stale rows shows the stored rows are identical to engine.insert's. Small seeds elsewhere still go through engine.insert.
What still runs for real. The at-ceiling admit case still runs its 20 000 real hook dispatches, which is the behaviour it pins.
Ablation. The same 59 tests run under the same titles. The red sets are equal, base copy vs branch: A (never refuses) 3/59 each; B (refuses at the ceiling) 1/59 each; C (before-hooks never dispatched) 13/59 each. Leg D (the helper seeds count−1 rows) turns the five ceiling cases red.
Wall. 3.1–3.4 s became 0.84–0.96 s alone, and 8.2 s became 1.8 s in a CI-shaped package run. The CI figure (about 4 s, by the box-to-CI ratio) is a projection; the next refresh PR's list measures it.

Landing checks at eb84ae2f62:

ci-failure.mjs --pr 23779 is GREEN: 40 of 40 check runs completed, none failed. The duplicated rows are label-event re-runs (skip-changeset), each skipped or successful.
git merge-tree against current main is clean.
The path face is 1 file (+37 / −15), not governed. skip-changeset is applied.
The body's first line is Part of #23182 (row 5), with no closing keyword.

Out-of-scope findings:

Acceptance notes: engine.insert costs about 40 µs a row on a 10 000-row batch and grows as the heap fills. That is a production insert-path optimisation, not a defect, so no card.
Acceptance notes: the cold import and transform phase of a single-file @objectstack/objectql run (about 11–13 s) sits on no module line. This is the same shape rows 1 and 4 noted.
Acceptance notes: the at-ceiling case's 60 000 ms timeout is left as it is, because the card forbids timeout changes. The case now takes 0.7 s, and lowering the timeout would be a separate decision.

Next: ready, then auto-merge through the queue.

The 16 320 generated rows now run in four shard files (shard-1 to shard-4, one registerRowShard() call each, the shard read off the file name) over one shared helper, protocol.lock-one-resolution.kit.test.ts, which holds the table, oracle, doubles, door, reads, readScenario, agree, the partition and the shard-set pin; the 40 named tests stay in the original file. Partition: a read group is a row's title with requestScope and operation blanked, groups are numbered in table order, group n goes to shard (n mod 4)+1, so the four rows that share a read stay together and step A's 4-to-1 memo holds per shard (1 020 groups, 4 080 rows each). Shards read 2.4-2.7 s alone (12 runs) against 8.0-8.4 s for the single file on main, and 3.7-4.0 s each in the CI-shaped package run (maxWorkers=8) against 21.3 s; no shard is near 4 s alone, so K stays 4. The same 16 360 full titles run (0 only in base), plus the pin's two tests; red sets under A1-A4 are equal to the single file's; the pin goes red on a deleted, renamed or emptied shard and on three partition faults. The helper is a .test.ts file because the three double gates scan *.test.ts only; the engine-double ledger row moved with the double (one row renamed). No production file changed. CI after the split is NOT MEASURED; the card's 113 s reading was 5.4x the local single file, at which ratio a shard would read about 14 s, so the next refresh's list decides whether K=6 is owed. Deviations: commits carry the model-free trailer pair from AGENTS.md, not the harness reminder's model-named trailer, and the PR uses the session-URL footer form; a container restart killed the first attempt before anything was committed, so the split was redone from the empty branch; the shard-file experiments P1-P3 first ran with wrong test paths and matched no file (zero tests, not a measurement) and were re-run with the paths fixed.

✅ ACCEPT (row 1, step B): PR #23790 at `7686410907` · `domain:engine` seat 2 · `session_01ADzJtzYTLUfgrRZHxkagkX` · 2026-10-16T03:04Z

Basis:

the claim 6203870579;
the seat's answer 6204945326 (A+B, K=4) and the step B note 6206011975;
the dev's report 6206773334;
the seat's own reading of the diff (7 files: one kit, four shard stubs, the named-tests file, one ledger row).

Review (in-seat; test files plus one gate-ledger row, no production file, no contract surface):

Partition. A read group is a row's title with requestScope and operation blanked. Groups are numbered in table order, and group n goes to shard (n mod 4)+1. So the four rows that share a read stay together, and step A's 4-to-1 memo holds per shard: 1 020 groups, 4 080 rows each.
The kit. protocol.lock-one-resolution.kit.test.ts holds the table, the oracle, the doubles, the door, the reads, readScenario, agree, the partition and the shard-set pin.
- Each shard file is one registerRowShard() call, and it reads its shard off its own file name.
- The kit registers its own pin tests only when it is the file vitest started on (expect.getState().testPath, kit.test.ts:734), so an importing shard does not run them again. A path that is neither a shard nor the kit is refused.
- It is a .test.ts file because the three double gates walk *.test.ts only. That follows an existing pattern: plugin-auth's impersonation-bearer-rotation.test is imported by fifteen siblings.
The pin. The shards' union is the full table (16 320 rows), each row lands in exactly one shard, and all four files exist. The dev's legs turn it red on a deleted shard, a renamed shard, an emptied shard, and three partition faults. It stays green under the four behaviour ablations.
Equivalence with the single file. The same 16 360 full titles run (0 only in the base), plus the pin's two. A1–A4 give equal red sets against the single file on main: 2384, 1823, 7744 and 8160.
The ledger. scripts/engine-double-contract.pinned.json renames one row, because the engine double moved into the kit. check:engine-double-contract, check:where-matcher and check:objectql-double-limit exit 0.
Wall.
- Shards run 2.4–2.7 s alone (12 runs), against 8.0–8.4 s for the single file on main.
- In the CI-shaped package run (maxWorkers=8 on 4 cores) they run 3.7–4.0 s each, against 21.3 s.
- The five extra file imports cost a few percent of the package run's wall (198 s → 211 s, one reading each).

Landing checks at 7686410907:

ci-failure.mjs --pr 23790 is GREEN: 40 of 40 check runs completed, none failed. The duplicated rows are label-event re-runs.
git merge-tree against current main is clean.
The path face is 7 files, 1 500 changed lines, not governed and under the 3 000 threshold. skip-changeset is applied.
The body's first line is Part of #23182 (row 1).

Out-of-scope findings:

Acceptance notes: the import cost of the five new files is the cost the seat's answer named, and the PR body carries it.
Acceptance notes: the three double gates walk *.test.ts only, so a double moved into a non-test helper would leave them silent. That is a stated scope in their headers, and it is why the kit is a .test.ts file. No card.
Acceptance notes: the dev's gate derivation ran on a tree 5 commits behind main (the check:route-envelope family's inputs changed upstream; its population is non-test packages/rest sources this diff does not touch). The queue builds this PR on current main, and that is the reading that counts.
Open until the next refresh. CI wall per shard is not measured. If the next refresh PR's list still names a shard, K=6 is owed under the same answer, with no exception needed.

Next: ready, then auto-merge through the queue.

Claim amendment (row 6), under the maintainer's 「23182 你可以处理吗」:

File surface: packages/drivers/driver-sql/src/sql-driver-connect-bound.test.ts, and a test-only helper it waits on.
Production code: if the time is spent in production code (sql-driver.ts's connect path, which PR fix(driver-sql): a sqlite file that cannot be created or opened fails connect at once, naming the file and the OS error (#23696) #23730 just changed), the dev stops and reports before editing it.
The card's limits hold: no deletion without a named duplicate, no timeout raise, no move to a slower or skipped project.
Branch: claude/issue-23182-connect-bound-budget. Worktree: objectstack-issue-23182-row6.
No overlap. No open PR touches the file (read just now).
Closing. The PR says Part of #23182 (row 6). When it lands, the seat closes the card completed with the row table. Each row's pin stays with the refresh lane, which files a card for any file its list still names.

Basis:

the row 6 claim amendment 6207502480;
the dev's report 6208068623;
the seat's own reading of the full diff.

Review (in-seat; one test file, no production file, no contract surface):

Where the time went. The one slow test ("actually bounds a query against a black-holing endpoint") waited out the driver's real 10 s pg connectionTimeoutMillis: 10 014 ms of the file's 10.1 s. PR fix(driver-sql): a sqlite file that cannot be created or opened fails connect at once, naming the file and the OS error (#23696) #23730 changed only the sqlite connect path, so this wait was unchanged on main.
The fix. The test keeps the real loopback black-hole listener (real net I/O and real microtasks) and fakes only setTimeout / clearTimeout. It waits until the server has accepted the socket, then advances the clock in 500 ms steps until the query settles, never past 20 s.
- That still proves the bound: pg's connectionTimeoutMillis and tarn's createTimeoutMillis are both armed on the faked setTimeout.
- Real timers come back before teardown.
Assertions. Every assertion is kept. The message names the connection attempt, and the elapsed time is over 8 000 and under 20 000. Two guards are added: still pending after 20 s of fake time means an unbounded connect, and a resolved query fails the test.
The timeout went down, not up. The per-test timeout is 15 000 ms, from 40 000.
Production code is untouched. DEFAULT_CONNECT_TIMEOUT_MS is private with no seam, and the card forbids shortening the pinned bound.
Ablation. All three legs go red on base and on the branch with the same shape. A: bound 10 s → 5 s, 5/16 each. B: dialect timeout injection disabled, 5/16 each. C: no bound at all, 8/16 each. Unmutated, 32/32 pass.
Wall. The module line went from 10.12–10.13 s to 127–132 ms alone.
