The CI round's leftovers in objectui: AGENTS.md section 9 still shows --shard=1/4, and three comments (changeset-release.yml ×2, check-unused-dependencies.test.ts) still say four coverage shards after objectui#12208 / #12256 moved the lane to eight

Filed by the director seat (summon #37, session_01LqNgdPZB2Jnr5HpGbaqLeB) under the maintainer's words 「立卡你决定，不需要我同意」 and 「后续能否你负责分析和立卡，具体的开发任务交给车道经理」 (2026-10-12): the seat files, the domain:devx lane manager claims, dispatches and lands. ⛔ Not a claim. Three carried items from objectui#12208's landing record (6133424464), gathered into one card because one PR carries them (AGENTS.md is governed: the PR stays a draft until a GOVERNED_APPROVERS member approves). Priority p3: comments and an example, no run changes.

The three items (as PR #12263's dev reported them, head `0e1a41c9`; re-read on today's `main`)

AGENTS.md section 9, the test recipe still gives --shard=1/4 as its example (the objectui#12208 dispatch's H5). Since PR ci(test): the coverage lane runs eight shards, then both test matrices shard by measured duration (objectui#12208, objectui#12256) #12263 (1fb1ced3) the coverage lane is 8 shards, the test lane 12, and scripts/test-shard-sequencer.mjs decides which files a leg runs (by measured duration from scripts/test-shard-timings.json, not by path hash), so the example should name a current width and say the sequencer places the files.
.github/workflows/changeset-release.yml: two comments say the push lane ran "coverage across four shards". Eight now (ci.yml test-coverage, COVERAGE_SHARDS: '8').
scripts/__tests__/check-unused-dependencies.test.ts: a comment says "on the merged 4-shard report". Eight now.

Acceptance

git grep -n 'shard=1/4\|four shards\|4-shard' -- AGENTS.md .github/workflows/changeset-release.yml scripts/__tests__/check-unused-dependencies.test.ts finds nothing; check-doc-links, check-control-bytes, check-new-cross-file-line-citations (0 new) exit 0; no behaviour changes (comments and a doc example only); the governed queue guard's verdict on AGENTS.md read and followed.

  "summary": "Draft PR objectui#12287 (head eb670ceb, base main, assignee os-justin, Tier H: GOVERNED on AGENTS.md) retires the four stale shard-width sites. (1) The AGENTS.md section 9 recipe example now says --shard=1/12. One paragraph directly under that fence says a local --shard=K/N runs through the root config's sequence.sequencer (scripts/test-shard-sequencer.mjs), which places files by the measured timings. Because the plan depends only on the file set, the timings and N, a local leg with a CI matrix width and no path filter runs the same files as that matrix's full-run leg. N is left to ci.yml's two matrices, and the text says the example 12 is not re-checked there (commandment 9). (2) The two changeset-release.yml comments and (3) the check-unused-dependencies.test.ts comment now point at the test-coverage matrix and every coverage shard instead of restating a number. H1 confirmed: 4 hits at 74964ad6, 0 at eb670ceb. H2 confirmed: test matrix 12, test-coverage 8, COVERAGE_SHARDS 8. H3 measured: the sequencer runs locally too. H4: 7 more present-tense sites of the same family exist outside the declared surface; all are listed and left untouched.",
  "tests": "At eb670ceb, through the shared verify lock: pnpm exec vitest run --maxWorkers=2 over 50 files.

Result: \"Test Files 50 passed (50)\" / \"Tests 2097 passed (2097)\" / \"os-verify-lock: VERDICT command-exit 0\". H3 probe, also locked: pnpm test --shard=1/2 over check-unused-dependencies.test.ts and coverage-shard-width.test.ts printed \"test-shard-sequencer: shard 1/2 runs 1 of 2 files, 21.8 s of 21.9 s by the per-file timings measured 2026-10-12T15:22:58Z; ...\" then \"Test Files 1 passed (1)\" and VERDICT command-exit 0. Ablation and reverse verification: n/a, because the diff is comments and one doc example and no assertion reads them. The acceptance grep is two-legged instead: 4 lines at base 74964ad6, 0 at eb670ceb, and the positive control finds 4. NOT MEASURED: type-check, because the edit is comment-only in one .ts file and changes no tsc input semantics.

Checklist (read on GitHub, not from the report):

PR shape: draft, base main, body line 1 Fixes #12278, a line-start Clause-②: no; a scan of the whole body finds no other closing keyword.
Scope: 3 files, +9/−7: AGENTS.md +3/−1, changeset-release.yml +4/−4, check-unused-dependencies.test.ts +2/−2. All are in the claimed surface. The one stretch is the AGENTS.md paragraph under the recipe fence, which the report declares; it is the card's own "say the sequencer places the files", inside the test-recipe block.
Spot-check of the new AGENTS.md paragraph against origin/main: vitest.config.mts sets sequence: { sequencer: TestShardSequencer } unconditionally, and the scripts/test-shard-partition.mjs header says "the plan is a pure function of (the file list, the dataset, M)". The paragraph's claims hold.
Changeset: none added. Changeset Declaration is success on eb670ceb, and the gate's verdict rules.
CI on eb670ceb: every check completed/success; the coverage legs are skipped by design on pull_request. mergeable_state clean.
Governed: check-governed-merges.mjs --pr objectstack-ai/objectui#12287 → GOVERNED, landing tier H (AGENTS.md), 16 changed lines.
Writes: mcp_calls 0; api_writes: 2 relay strokes (pr_create with assignee, the report comment).

Deviation accepted: the three comments carry no number instead of the card's "Eight now". They point at the test-coverage matrix, so the next width change cannot strand them. The acceptance grep is empty either way.

Out-of-scope readings (7): each is Acceptance notes, listed in the PR body. These are stale shard-width prose in CONTRIBUTING.md, scripts/select-affected-tests.mjs, two ci.yml comments, check-lockfile-dedupe.test.ts, check-hand-rolled-comment-mask.mjs and markdown-test-inputs.mjs. None is one of the four card types, and no reader can be named, so none is filed.

Next: Tier H. The PR stays a draft and carries needs-user-decision, with the final 维护者速读 on the PR. A review is requested from both GOVERNED_APPROVERS. On an authorised approval, the seat lands it (ready + auto-merge). The card stays pm:dispatched until MERGED.
