ci: run Windows tests in fourteen shards with refreshed weights - #8605
The dev batch run 43257334898 (9fec48a1f8) passed 41 jobs, but windows 8/11 hit the 30-minute job timeout and was cancelled in batch 44/52. Nothing hung; the Windows lane has outgrown eleven shards. In the same run the other ten Windows shards took 19.4–29.9 minutes, and 2/11 finished at 29:55.
Two problems combined:
Too much work for eleven shards. Measured Windows test work is 16,496 s, against the table's 14,874 s for the same files. Balanced over eleven shards that is ~25.0 minutes of tests per shard. With the 25% variance and 2.4-minute setup the ci.yml history uses for this sizing, that projects ~33.6 minutes against the 30-minute bound.
Stale weights. New and grown files carried default or old weights (for example codex-eager-tool-catalog measured 86.9 s against a 0.4 s default, and server-combo-failover-e2e grew by 70 s). That's why 8/11 drew ~1,650 s in 44 batches while 5/11 finished at 1,065 s, although every shard was predicted at 1,369 s.
This PR does what the last expansion (nine to eleven, run 40756291846) did: refresh the weights and add shards, keeping the 30-minute job bound and every test.
scripts/ci/test-durations.windows.tsv: regenerated with scripts/ci/test-durations.ts refresh from all eleven Windows shard logs of run 43257334898 (3,067 files measured; files after 8/11's last batch keep their earlier rows).
.github/workflows/ci.yml:platform-windows goes from 11 to 14 shards: the matrix, TEST_SHARD, the job name, and the aggregate gate's shards= leg count, with the sizing rationale appended to the existing history comment. timeout-minutes stays 30.
.github/scripts/release-evidence.cjs: release evidence holds each run to the Windows leg count of the policy entry its revision matched. A ci entry now records windowsShards. Entries without it pinned the eleven-shard workflow and mean eleven, so a historical revision stays verifiable against its own entry, and a fourteen-shard revision still can't pass with eleven legs. An invalid count fails closed. The current job set (windows 1/14 … windows 14/14) follows the newest entry.
.github/scripts/release-evidence-policy.json: appends one ci entry with windowsShards: 14, identical to the latest except that field and the new blobs for ci.yml, release-evidence.cjs, release-evidence.test.cjs and the Windows duration table. Earlier entries stay unchanged.
Docs and tests:AGENTS.md's job count for a lane=all run, and the expected matrix in tests/ci-workflows/ci-workflows.test.ts.
Simulating the batch runner's own greedy assignment on the refreshed table:

25.0 min
33.6 min
13
21.1 min
28.8 min
14
19.6 min
26.9 min
Fourteen matches the ~27.3-minute margin chosen for eleven. The cost is three more Windows setups per batch (about 7 runner-minutes); macOS slots are not affected.
Why the slow tests themselves aren't shortened here. The heaviest Windows-only files (codex-cli-update-windows-recovery, -apply-install, -apply-outcomes, -apply-shared, ~950 s together) spend their time in fixture setup the tests treat as the proof. Each test copies the full npm module tree, runs required ACL hardening, then does a full native npm-tree ACL renewal with real children. Even cases with an injected installer take ~20 s. Those tests only run on Windows x64, so a speedup can't be measured or verified without a Windows host, and cutting the fixture blind would weaken what they prove. That work belongs in a follow-up measured on Windows.
Release transition. Release evidence reads the candidate's own lane=all run and checks it against the policy entry that revision matches, so older eleven-shard revisions keep their eleven-leg requirement and new revisions need fourteen.
Verification
node .github/scripts/release-evidence.cjs policy-check: "Evidence policy fingerprints match the working tree."
node --test .github/scripts/release-evidence.test.cjs: 26 pass, 0 fail. The new case covers four things: a legacy entry accepting an eleven-leg run, a fourteen-shard entry rejecting eleven legs, a legacy entry rejecting fourteen legs, and an invalid count failing closed. It fails when the job check goes back to the newest entry's set.
bun test tests/ci-workflows/: 1,934 tests across 97 files on the first head, 0 fail. On the final head, two timing-based tests in package-tree-fenced-restart.test.ts failed under load; that file passes alone (3/3) and isn't touched here.
bun run structure:check and bun run privacy:scan: pass.
Shard simulation above uses the same greedy rule as run-bun-test-batches.sh (heaviest first to the least-loaded shard, median for a file without a row).
NOT RUN: a Windows lane=all run with fourteen shards (the coordinator runs the dev batch after merge; no per-PR lane=all dispatch), full bun run test.
Checklist
Scope stays focused and avoids unrelated cleanup.
Docs or release notes were updated when needed. (AGENTS.md job count; rationale in ci.yml.)
Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults. (Workflow and release-evidence changes; separate security review requested.)
Summary by CodeRabbit
Chores
Windows CI testing is now divided into 14 shards, up from 11; the 30-minute job timeout is unchanged.
Updated CI documentation to reflect revised run-size estimates: 46 jobs for a full manual run, requiring more than five runner-hours.
Release evidence now uses the approved Windows shard count for each run and checks that the reported job count matches the applicable policy.
Tests
Updated CI workflow checks for 14 Windows shards and added coverage for release-evidence policy validation.
Run 43257334898 cancelled windows 8/11 at the 30-minute bound in batch
44/52 while the other ten took 19.4-29.9 minutes. Measured Windows test work
is 16,496 s; balanced over eleven shards that projects ~33.6 minutes with
the variance and setup the ci.yml history uses, and stale weights put far
more on 8/11 than on 5/11.
Refresh test-durations.windows.tsv from that run and move platform-windows
to fourteen shards (matrix, TEST_SHARD, job name, aggregate leg count), which
projects ~26.9 minutes. The 30-minute job bound and every test stay. Release
evidence requires the fourteen legs, and the release evidence policy gains a
ci entry with the new blobs; earlier entries are kept.

Summary
Derive release-evidence jobs from policy .github/scripts/release-evidence.cjs, .github/scripts/release-evidence-policy.json, .github/scripts/release-evidence.test.cjs
The release-evidence script validates policy shard counts and derives required Windows jobs from the policy that matches each run. Missing counts default to 11; counts outside 1–64 are rejected. The policy record and tests cover the 14-shard policy, legacy policies, invalid counts, and mismatched run counts.
Expand Windows matrix and update checks .github/workflows/ci.yml, tests/ci-workflows/ci-workflows.test.ts, AGENTS.md
The workflow matrix, test-step shard total, and aggregate check change to 14 Windows shards. The workflow test and lane=all estimate reflect the change. The per-job timeout remains 30 minutes.

Historical CI evidence validation uses the current fourteen-job set.
eligible validates every CI run against the current CI_JOBS at .github/scripts/release-evidence.cjs:209, after the policy match at line 207. An eleven-shard revision that matches its retained historical policy still lacks windows 12/14 through windows 14/14. validateJobs then throws missing or unsuccessful job, and qualifies skips the run at line 217. Requesting that older SHA can therefore fail with "no qualifying" run, even though the policy header says historical revisions must remain usable.
The expected job set needs to come from the matched policy or revision rather than the current constant. assertPolicy does not return the matched policy, and the policy entries store no job list, so the correction needs a design change in the policy data and its matching. Keep the fourteen-job requirement for the new policy. Add a fixture that validates an eleven-shard historical run against its own policy.
Severity: this blocks historical release-evidence verification for older revisions. It does not affect the current fourteen-shard path.

A run was validated against the newest job set, so an eleven-shard
revision that matches its own retained ci policy would fail on windows
12/14..14/14 and stop being verifiable. A ci policy entry now records
windowsShards; entries without it pinned the eleven-shard workflow and mean
eleven. assertPolicy returns the matched entry, and the jobs are checked
against that entry's count, so a fourteen-shard revision still cannot pass
with eleven legs. An invalid count fails closed. AGENTS.md's runner-hour
estimate now reads more than five.

The release evidence job set is 46 jobs: 18 on Windows (14 shards plus
the keyring, setup-action, remote-helper and npm-global legs), 9 on macOS
and 19 on Linux. The line counted only the Windows test shards.
Maintainer judgment: merge. Exact head bd7ab23c3c.
This fixes the DEV-RED from dev batch run 43257334898, where windows 8/11 was cancelled at the 30-minute job limit. The Windows lane had outgrown eleven shards: measured Windows test work is 16,496 s, and stale weights left 8/11 far heavier than 5/11. This PR:
refreshes the Windows duration weights from that run;
moves platform-windows to 14 shards, keeping the 30-minute bound and every test;
makes release evidence hold each run to the Windows leg count of the policy entry its revision matched, so older eleven-shard revisions stay verifiable.
Evidence on this head
CI: all 31 checks pass.
Final general review, split because of reviewer request-size limits:
Part A (sizing) approved on cursor/grok-4.7. Greedy packing of the refreshed table gives a slowest shard of 24.99 / 21.15 / 19.64 min for 11 / 13 / 14 shards.
Part B (release evidence and CI) approved on morph/morph-dsv41flash-1017. The new test fails if the job check reverts to the newest policy entry.
The synthesis review approved on gpt-6.1-terra. Every changed file is covered by one of the reviews.
Security review: approved on cursor/grok-4.7, as required for workflow and release-automation changes:
the ci.yml diff touches only the shard count, TEST_SHARD, the job name, the aggregate leg count and comments;
validateJobs is unchanged, and an invalid windowsShards fails closed;
all 26 new policy pins match git hash-object.
CodeRabbit: all three findings were addressed (historical-revision evidence, runner-hours wording, and the 46-job count).
Windows impact. Every dev batch now runs 14 Windows test legs instead of 11: three more runner setups, about 7 runner-minutes. The projected slowest shard is about 26.9 min against the 30-minute limit, with 25% variance included. Release evidence for revisions on this workflow now requires windows 1/14 through windows 14/14. Older revisions keep their eleven-leg requirement through their own policy entries.
Not shortened here. The slowest Windows-only update/apply tests spend their time in fixture work that is the proof itself: a full npm tree copy, ACL hardening, and a native ACL renewal with real children. Shortening them needs measurement on a Windows host, so that is a follow-up.
NOT RUN: a Windows lane=all run with 14 shards (the coordinator runs the dev batch after merge), and full bun run test.
