ci(self-tests): the shard sizes /3, /8, /16 are copied into five self-tests and fixtures — read them from the workflow's matrix blocks

Filing gate: ③ maintainer-directed. Maintainer, 2026-10-27, in the director summon chat, to the seat's check-retirement sweep and its offer of three cards, verbatim: 「同意」 (the sweep was ordered by 「排查一下还有哪些检查应该退役」). Filed by the director seat (session_01KrKXQVvgYk2AJ4VkqMobyb, ledger objectstack#12708, sweep record 6433263738). ⛔ Not a claim. Batch-of: 11 (director seat, 2026-10-27). Dedupe: 600 newest open + closed issues grepped for the check's file name → 0 unless stated. Part of #26431. Reader: domain:devx (ci scripts) and domain:ui for the two ui fixtures.

Measured: shard-count literals live in scripts/partition-test-shards.mjs:160, scripts/check-required-contexts.mjs:2068–2083 (self-test asserts ci.yml contains Test Core (${{ matrix.shard }}/8)), scripts/check-shard-attestation.mjs:2257, 2821, scripts/pm/check-expected-skips.mjs:316, 330, 359 (the roster child handles these), ui/scripts/__tests__/select-affected-tests-wiring.test.ts:54 and select-affected-tests.test.ts:450 (/16). Changing a matrix size means editing every one; none of them is the authority (ci.yml's matrix: blocks are).

Wanted: one small reader of ci.yml's matrix sizes (or the existing parser in check-required-contexts) that the self-tests and fixtures call, so the literal appears once — in the workflow. Acceptance: git grep -nE "/(3|8|16)\b" scripts/*.mjs scripts/pm/*.mjs ui/scripts/__tests__/*.ts shows no shard-size literal outside the reader; all self-tests green. Size: S. Clause-②: no. Metadata-protocol: none.

Claim: PM loop round 10 · 2026-10-27T04:23Z
Session: session_01Q4MDXRbEJCNdPAP4SiXwp9 (devx seat 2) · card thread cmsg_01FdL1XeUyvVNxLreh3F4Qi9MKqYfea9FwGdabNwe4CdFw
Account: os-steve
Branch: claude/project-thread-6wlskb (the harness-pinned branch of the card thread; it names no issue, so this claim is the identity record; amended on spawn)
Worktree: objectstack-issue-26443
Domain: domain:devx
Seat: domain:devx#2 (seat post #20163)
File surface: the devx half only — one reader of .github/workflows/ci.yml's matrix: shard sizes (a new scripts/lib/ helper or the existing parser in scripts/check-required-contexts.mjs), called by scripts/partition-test-shards.mjs, scripts/check-required-contexts.mjs self-test, scripts/check-shard-attestation.mjs (L2257, L2821) so the literals /3, /8, /16 sit only in the workflow. ⛔ ci.yml read, never edited; ⛔ scripts/pm/check-expected-skips.mjs left to the roster child of #26431; ⛔ the two ui/scripts/__tests__/** fixtures are domain:ui (reported for a ui card, not touched)
Container & model: S, mode:thread, model: default tier (TIER_DEFAULT, from dispatch-gates --tier: no path-derived mandate), effort: medium
Clause-②: no
Metadata-protocol: none
Responsibility: n/a — maintainer-directed filing (sweep 6433263738), Part of #26431
Thread-read: none
Premise: the shard-size literals are at the card's measured lines on origin/main (the dev re-greps first)
Serial constraints cleared: #26091 (this seat, in flight) edits check-aggregator-roster, check-ci-filter-parity, check-doc-frontmatter self-tests and lint.yml; disjoint files

devx seat 2 · devx half released: PR #26488 (Part of #26443, Part of #26431) merged as e5131cfb. Its +/- lines on main match the reviewed head 35440f1d in all 5 files. scripts/ci-shard-matrix.mjs is now the one reader of ci.yml's shard sizes. partition-test-shards, check-required-contexts and check-shard-attestation read it, and their /3, /8, /16 literals are gone.

Left on this card (domain:ui): ui/scripts/__tests__/select-affected-tests-wiring.test.ts:54 and select-affected-tests.test.ts:450–453 still spell /16. They can call shardTotal(text, 'test-ui') from scripts/ci-shard-matrix.mjs. pm:retriage: please route this remainder to domain:ui (a lane change on an undispatched card is triage's act). The devx seat drops its assignee and pm:dispatched, and the card goes back to pm:queue.

devx seat 2 · pm:retriage withdrawn: ui seat 1 has taken the ui/scripts/__tests__/** remainder (the two /16 spellings) in its own card thread, so no lane change is needed. The card stays pm:queue for that seat's claim.

Both halves of this card have landed, so devx seat 2 (#20163) closes it.

devx half: PR ci(scripts): read the shard sizes from ci.yml's matrix blocks instead of copying them #26488, merged as e5131cfb (scripts/ci-shard-matrix.mjs and its self-test).
ui half: PR test(ui): read the Test UI shard width from ci.yml instead of spelling /16 #26516 (ui seat 1), merged as add806c5. On main, both ui/scripts/__tests__/select-affected-tests*.test.ts files now import shardTotal from scripts/ci-shard-matrix.mjs instead of spelling the shard count.
