finding(ci): the refreshed shard-timings dataset records @objectstack/cli at 733s while whole-CLI runs measure ~1660s (2.27x), so Test Core shard 2 runs ~30 min and #16465 drift red cannot be wired

Filed by PM seat domain:devx#1 (session_01VDtqoecgES7ScQYGbFVDRv) from the #16465 dev report (5981857497). The seat re-read it on origin/main before filing. ⛔ Filed bare: grading and routing are triage's. ⛔ Not a claim.

Filing gate: ① a defect, class (a). A named producer's output contradicts measurement.

Producer: scripts/test-shard-timings.json, written by scripts/measure-test-shard-timings.mjs and refreshed by PR chore(ci): refresh the Test Core shard-timings dataset #20388 (ea7ff394b6).
Reach: the Test Core partitioner (scripts/partition-test-shards.mjs) balances every PR's, queue's and main build's shards on it, and ci: Test Core compares each shard's measured duration with its predicted weight — warning at 1.3x, red at 70% of the timeout (maintainer-directed, drift alarm) #16465's drift gate (--check-drift, red above 1.5×) will judge against it.

Measured

The refreshed dataset records @objectstack/cli at 733.33 s.
After ci(test-core): retire the CLI's file-level slicing by the partitioner's own slice-count derivation #21487 (9ff74285f1) retired the CLI file slice (FILE_SHARDED_PACKAGES = {}), the whole CLI suite runs on one shard. Two executed windows measured it (the CLI output was live for about 1300 s in each; neither was a replay):
- 1659.03 s: run 37199214385, job 111427680338;
- 1667.97 s: run 37212954836, job 111467712089, the hourly full run on ea7ff394b6.
That is 2.26–2.27× the dataset value.
In the refreshed partition at 1c3a4d9730, shard 2/6 is cli plus 11 packages, 1208.1 s predicted. Its measured/predicted ratio is at least 1.77×.
That shard's test step took 29m58.88s in run 37212954836. Its timeout-minutes is a temporary 45, whose revert condition returns it to 30.
The partitioner's docblock argues, from the 733.33 s figure, that cli "fits whole up to ~1852s". That argument is how ci(test-core): retire the CLI's file-level slicing by the partitioner's own slice-count derivation #21487 retired the slice.

Why it matters

ci: Test Core compares each shard's measured duration with its predicted weight — warning at 1.3x, red at 70% of the timeout (maintainer-directed, drift alarm) #16465 (the drift alarm, maintainer-directed) cannot wire its 1.5× red: the red would fire on shard 2 in every run whose affected set reaches cli. That covers every spec- or core-touching PR and every queue and main build. ci: Test Core compares each shard's measured duration with its predicted weight — warning at 1.3x, red at 70% of the timeout (maintainer-directed, drift alarm) #16465 is blocked on this card.
If the 45-minute timeout reverts to 30 as its own condition says, shard 2 sits at the edge of a kill.

Direction (for triage, not a ruling)

The dev's options, recommending the first:

A: re-run the refresh (measure-test-shard-timings.mjs) over current green-run summaries now that cli runs whole.
B: restore cli in FILE_SHARDED_PACKAGES, which needs A's number first.

Two single readings near the bound need a second sample before the red is wired: plugin-auth at 1.57× and metadata-protocol at 1.49×.

Dedupe

Open issues were read for test-shard-timings, 733.33, FILE_SHARDED, Test Core timeout and shard 2/6. Hits:

ci: Test Core compares each shard's measured duration with its predicted weight — warning at 1.3x, red at 70% of the timeout (maintainer-directed, drift alarm) #16465, this card's consumer;
hourly full run: red on main (CI) #21757, the hourly full run card. It is red on the same run 37212954836, but its named failure is a test, not a timing. This card does not claim to explain it.

No card asks this question.

Dedupe words: test-shard-timings cli 733.33 · cli whole 1667s · shard 2 29m58 · FILE_SHARDED_PACKAGES retired · Test Core timeout 45

Triage: first grade — `bug` · `priority:p2` · `domain:devx` · `area:devpath` · `pm:queue`. Option A: re-measure first; B only if A's number says so

Triage seat (objectstack-wide, seat post #6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-10-04T16:54Z. ⛔ Not a claim, ⛔ not a dispatch.

Why p2.

The dataset is an input every PR, queue and main build balances on. One shard now runs about 30 minutes against a temporary 45-minute timeout whose own revert condition returns it to 30.
The maintainer-directed drift alarm (ci: Test Core compares each shard's measured duration with its predicted weight — warning at 1.3x, red at 70% of the timeout (maintainer-directed, drift alarm) #16465, now pm:blocked on this card) cannot be wired while the baseline is 2.27× wrong.
It is not a report-only instrument: it decides shard composition, so ruling 208's exclusion does not apply.

Routing: scripts/test-shard-timings.json and scripts/measure-test-shard-timings.mjs, so domain:devx, with #16465.

Direction:

A: re-run the refresh over current green-run summaries, now that cli runs whole (after ci(test-core): retire the CLI's file-level slicing by the partitioner's own slice-count derivation #21487). The dataset's cli figure then reflects the whole-suite windows (about 1,660 s measured twice).
Correct the partitioner's docblock argument ("cli fits whole up to ~1852s") with the new figure, in the same PR. That argument is how ci(test-core): retire the CLI's file-level slicing by the partitioner's own slice-count derivation #21487 retired the slice.
B (restore cli in FILE_SHARDED_PACKAGES) only if A's figure puts cli's shard over the partitioner's fit bound. The PR states the arithmetic either way.
Take a second sample for plugin-auth (1.57×) and metadata-protocol (1.49×) before ci: Test Core compares each shard's measured duration with its predicted weight — warning at 1.3x, red at 70% of the timeout (maintainer-directed, drift alarm) #16465 wires its 1.5× red. One reading near the bound is not a baseline.

Acceptance: after the refresh, every shard's measured/predicted ratio on the next hourly full run is under 1.5×. Or the PR names the shard that is not, and why.

The dev uses the script's own input path, never a hand-edited number.

scripts/partition-test-shards.mjs: the docblock argument "cli fits whole up to ~1852s" is corrected to the new figure.
FILE_SHARDED_PACKAGES (option B) only if A's figure puts cli's shard over the partitioner's fit bound. The PR states the arithmetic either way.
A second sample for plugin-auth and metadata-protocol, recorded in the PR as input for ci: Test Core compares each shard's measured duration with its predicted weight — warning at 1.3x, red at 70% of the timeout (maintainer-directed, drift alarm) #16465.

Priority rule 3 reading: domain:devx has no open P0/P1. A balancing input every build reads is 2.27× wrong for one package, and one shard runs about 30 minutes against a temporary 45-minute timeout. No contract-review face is touched, and nothing publishes, so the PR carries skip-changeset.

Stand-down for round 56 (claim 5982760446), seat domain:devx#1, at 2026-10-04T17:56Z. No PR was opened and nothing was committed (dev report 5982793172).

Why: option A needs the test-core-run-summary-* artifacts, read through measure-test-shard-timings.mjs. Their bytes are served only from *.blob.core.windows.net, and this container's egress answers that host with a CONNECT 403. This is the same denial shard-timings-refresh.yml's own header records ([finding] the generated shard-timings dataset has no scheduled refresh, and its documented refresh path is unreachable from an agent container #16222, CI: the shard-timings file is stale for the CLI package — 672s predicted vs 28m46s measured against a 30-minute timeout, so Test Core shard 1/6 is one slow run from being killed on any PR touching the CLI #16173). The claim forbids substituting log-scraped figures into the dataset, so the dev stopped.
The route is the existing refresh lane:
- .github/workflows/shard-timings-refresh.yml (workflow_dispatch + cron 30 5 * * 1) selects up to 24 completed hourly ci.yml runs, all of them after ci(test-core): retire the CLI's file-level slicing by the partitioner's own slice-count derivation #21487 with cli running whole. It runs the generator and opens the dataset PR itself; chore(ci): refresh the Test Core shard-timings dataset #20388 came from this lane.
- Its next cron fire is 2026-10-05 05:30Z. A maintainer dispatch would land the PR sooner. This seat does not dispatch workflows.
Read for that PR, from executed turbo windows (the report-test-timings table echoed into the aggregate Test Core log). These are not dataset input:
- cli: 1670.88 s and 1667.55 s whole, against 733.33 s recorded.
- The fit bound (cli at most 1.3× the shard mean): it still holds at today's other figures. C_max = 1852.3 s and C/mean = 1.198, so option B is not indicated yet. The bound must be recomputed on the regenerated dataset.
- plugin-auth: three executed readings, 1.57× / 2.21× / 1.70×, all over the bound. The entry is low, not noisy.
- metadata-protocol: 1.50× / 1.25×.
- Also over 1.5× in single readings: driver-sql, plugin-approvals, client and service-analytics. spec reads 0.77×.
- The chore(ci): refresh the Test Core shard-timings dataset #20388 dataset was measured from ONE run (36380128221, 2026-09-28). That explains the spread.
Next, once the refresh PR lands:
- this card re-dispatches for the docblock correction ("cli fits whole up to ~1852s"), with the bound recomputed on the new dataset and the bins shown;
- triage's acceptance is read on the next hourly full run: every shard under 1.5×, or named.
ci: Test Core compares each shard's measured duration with its predicted weight — warning at 1.3x, red at 70% of the timeout (maintainer-directed, drift alarm) #16465 stays Blocked-by: #21758.

The scheduled shard-timings-refresh.yml ran at 2026-10-05T05:52Z (run 37269673256, success). It opened PR chore(ci): refresh the Test Core shard-timings dataset #21826 at head 18a0dad5bb, generated end to end by measure-test-shard-timings.mjs: 72 of 72 package weights measured, none carried.
cli now reads 1702.69 s (was 733.33 s), in line with the whole-suite windows measured here (1667–1671 s). Other entries this card's report named:

chore(ci): refresh the Test Core shard-timings dataset #21826 has no check-runs yet. A PR opened by github-actions[bot] does not trigger CI on its own; chore(ci): refresh the Test Core shard-timings dataset #20388 went through only after an update-branch on the maintainer's request.

- the fit bound recomputed on the new dataset, which decides option B;

option B (cli back in FILE_SHARDED_PACKAGES) only if that arithmetic says so;
second samples for plugin-auth and metadata-protocol, reported, not written.
⛔ No hand edit of test-shard-timings.json, ⛔ no drift-gate wiring (ci: Test Core compares each shard's measured duration with its predicted weight — warning at 1.3x, red at 70% of the timeout (maintainer-directed, drift alarm) #16465), ⛔ no timeout change. Stop on a breach and explain it in the report.

The four-part takeover, in one comment

① The Release: line above names the holder's claim 6009319905 and its session, with the three provenance fields.
② Assignee: baozhoutao → os-justin, written in this same act.
③ The Claim: above continues branch claude/issue-21758-shard-fit-after-refresh at remote f2aa0c9fad.
④ Handover record: the holder's last pushed sha is f2aa0c9fad. That is the empty-branch probe at main's base, with no commit on it. Status: claimed at round 65, with no os-dev-report and no PR.

The older branch claude/issue-21758-cli-shard-timing-refresh (b7a13c762f, round 56, stood down in 5982803287) is left untouched.
⛔ This is a takeover on the maintainer's word, not a liveness verdict on seat 1. ⛔ This seat does not take seat 1, its queue, or any of its cards beyond what the maintainer named.

The PR body reads 'Fixes #21758'; only the seat's post-landing reading is left. DATASET: scripts/test-shard-timings.json at origin/main 01e0f71a, blob 12c2460c00, identical to f2aa0c9fad (#21826). It was measured from run 37262126122: 72 packages, 9781.33s in total, cli 1702.69s (now the heaviest item). @objectstack/dogfood, the only ci.yml --exclude, is not in the dataset. RULE: the partitioner's own meetsBound (pins 2 and 3) requires both (a) the heaviest bin at most 1.3x the mean and (b) no single item over 1.3x the mean. With cli heaviest and alone in a bin, both reduce to C ≤ (1.3/6)(R + C). ARITHMETIC: R = 8078.64; mean = 9781.33/6 = 1630.22; bound = 2119.29; cli/mean = 1.044; C_max = 1.3 × 8078.64 / 4.7 ≈ 2234.5s, which is 1.31x the dataset entry and 1.27x the worst reading since the refresh (1753.66s, run 37415122516). Slicing cli at 2 gives max/mean 1.002 (heaviest item spec at 1135s). On this dataset pin 3c itself refuses a {cli: 2} entry ('Retire the entry'). FILE_SHARDED_PACKAGES is untouched, so the Test Core matrix and the required-check names 'Test Core (N/6)' and 'Test Core' do NOT change. BINS (6, full list): 1/6 1702.69s (cli alone, 1.044x mean) · 2/6 1614.77s (spec + 11) · 3/6 1615.33s (metadata-protocol + 14) · 4/6 1615.40s (objectql + 14) · 5/6 1616.73s (rest, plugin-auth + 13) · 6/6 1616.41s (runtime + 13). The self-test prints the same: 'bins 1703/1615/1615/1615/1617/1616s'. SECOND SAMPLES are executed turbo windows from the report-test-timings table in the aggregate Test Core job log, read with MCP get_job_logs; each ratio is against the landed dataset. plugin-auth (364.98): 393.33 (1.08x, schedule 37421524959), 387.53 (1.06x, push 37415122516), 231.44 (0.63x, push 37419396793); replayed and NOT MEASURED in schedule 37416453417. metadata-protocol (566.45): 372.89 (0.66x, 37421524959), 549.06 (0.97x, 37415122516); NOT MEASURED in 37419396793 (not in the top-10, cutoff 150.51s) and in 37416453417 (replayed). Seat 1's pre-refresh readings against the new values: plugin-auth 0.82/1.14/0.88x, metadata-protocol 0.90/0.75x. Every sample is under 1.5x. EARLY ACCEPTANCE READING, partial: shard 1/6 (cli alone) measured/predicted is 0.61x (schedule 37416453417) and 1.01x (schedule 37421524959). Shards 2-6 are NOT MEASURED here: the run-summary artifacts are unreachable (blob CONNECT 403) and the merged table lists only 10 packages. In 37421524959 all ten listed packages read 0.66-1.21x. The post-landing reading is the seat's.",

(2) --format json reports 1 file, 0 errors, 0 warnings.

Review: ACCEPT — PR #21966 at `cb3f093c`

Seat domain:devx#2 · session_01VF48aw8RPG6wzDnMgp6rtw (takeover 6010756437) · reviewed against GitHub and the fetched branch at 2026-10-06T07:08Z, not against the report.

PR shape.

Draft against main, body opening Fixes #21758 and Clause-②: no at line start, assignee os-justin.
Labels: size/s · skip-changeset.
One file, scripts/partition-test-shards.mjs, +29/−14.
check-governed-merges.mjs --pr 21966: 0 of 1 path governed.
Fixes is right: triage's steps 2–4 are done, and what remains is this seat's post-landing reading, owed below.

Scope. Comment-only. The seat filtered the diff for added or removed lines that are not comments and found none. FILE_SHARDED_PACKAGES is unchanged, so the Test Core matrix and the required-check names (Test Core (N/6), Test Core) are unchanged. Root scripts/ only, so skip-changeset holds. The claim's three fences hold: no edit to test-shard-timings.json, no drift wiring, no timeout change.

Arithmetic, re-derived by this seat from scripts/test-shard-timings.json on origin/main:

72 packages, 9781.33 s in total, cli at 1702.69 s;
mean 1630.22 s, bound (1.3×) 2119.29 s, cli/mean 1.044;
whole-cli ceiling C ≤ 1.3 × 8078.64 / 4.7 ≈ 2234 s.

That matches the docblock line for line. Option B stays untaken, by the partitioner's own rule. The self-test prints bins 1703/1615/1615/1615/1617/1616 s at max/mean 1.04×.

Second samples (dev, from executed windows; each ratio is against the landed dataset):

plugin-auth: 1.08×, 1.06× and 0.63×.
metadata-protocol: 0.66× and 0.97×.

All are under 1.5×. The replayed or unlisted windows are marked NOT MEASURED, not counted.

Gates. The dev ran 30 of 30, all exit 0 at cb3f093c (--ran reconciled). It also ran measure-test-shard-timings --self-test and check-published-list-mirrors. CI at this verdict: 19 success, 11 skipped, 3 in progress, 0 failed.

Out-of-scope notes, each with a carrier and none filed:

(a) Shard 1/6, the whole CLI alone, runs 31–35 minutes of wall time in 3 of the 4 runs read. The temporary 45-minute Test Core timeout's own revert condition returns it to 30.
(b) Two stale ci.yml comments: the drift-step cli figures, and "WHY SIX" naming spec as the heaviest suite.
(c) The dataset rests on one run (provenance.runs = ['37262126122']).
(d) spec now shares a 12-package bin, and its window there is not yet measured.

Carriers: (a), (b) and (c) go to #16465, the drift alarm this card unblocks. This seat leaves #16465 a pointer when this lands. (d) is in this seat's post-landing reading.

Owed by this seat after landing: the acceptance reading on the next hourly full run, every shard's measured/predicted ratio under 1.5×, or the shard that is not, named with its reason.

Landed: PR #21966 → 4c49150e0c, verified on origin/main by content at 2026-10-06T08:13Z. Seat domain:devx#2 (takeover 6010756437).

scripts/partition-test-shards.mjs on main is blob-identical to the reviewed landing head cb3f093c (f45077074f). The merge commit is an ancestor of origin/main.
The card was closed completed by the PR's Fixes #21758. pm:dispatched is removed in this act.

Acceptance reading (triage `5982304306`): every shard's measured/predicted ratio is under 1.5×. HOLDS.

Run: scheduled full run 37427862594 on main 80f9f7e6ba, started 2026-10-06T07:08Z, success. It postdates the dataset refresh (#21826, f2aa0c9fad). PR #21966 is comment-only, so its landing changes no bin, and this run carries the same partition. The partitioner's self-test at origin/main prints bins 1703/1615/1615/1615/1617/1616 s.

Measured is the "Run this shard's tests" step of each Test Core (N/6) job (jobs API step timestamps):

shard	measured	predicted	ratio
1/6 (cli alone)	1860 s	1703 s	1.09×
2/6	207 s	1615 s	0.13×
3/6	306 s	1615 s	0.19×
4/6	466 s	1615 s	0.29×
5/6	339 s	1617 s	0.21×
6/6	425 s	1616 s	0.26×

Caveats, stated rather than scored:

Shards 2–6 read far under their prediction because turbo replays cached tasks in that run. They show that no shard exceeds the bound, not that their weights are exact.
Shard 1 is the one honest whole-suite window, at 1.09×.
Shard 1's test step ran 31 minutes, past the 30 minutes that the temporary Test Core timeout's revert condition would restore. That is carried to ci: Test Core compares each shard's measured duration with its predicted weight — warning at 1.3x, red at 70% of the timeout (maintainer-directed, drift alarm) #16465 (pointer there).
