[Decision] Three scheduled workflows nobody reads: retire Spec Coverage (nightly) and Engine Split Metric (weekly, report-only), and fold Showcase Smoke into Nightly Tiers — or keep them

Ruled: 6433804956 · letter B · 2026-10-27T04:32Z

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. Filing gate ②: a maintainer-only decision (retiring a workflow is a governed-surface change under .github/workflows/**; the maintainer asked which checks to retire). Reader after the ruling: domain:devx (one Tier H PR).

维护者速读

三条定时工作流各有问题：Spec Coverage（每天 05:00，带覆盖率插桩跑 spec 全套）自己的文件头写着「趋势产物最多偶尔看一眼」；Engine Split Metric（每周一，ADR-0076 D7 引擎跨包提交比）只出报告、不设门，「阈值定了才设门」，没人在等这个阈值；Showcase Smoke（每天 07:00，showcase 每个导航面渲染健康）文件头说「稳定后升为 PR 门」，从未升，30 天 8 红 22 绿，红了也不开卡没人读，而 ui 并仓后 Build & E2E UI 已在每个 PR 上构建控制台。请裁：A 三条全退；B 退前两条，Showcase Smoke 并进 Nightly Tiers（它红了会开卡）；C 三条都留。

一句话问题

三条没有读者的定时检查每天花 runner 时间，红了也不会变成任何人的任务。

Governing text

.github/workflows/coverage-nightly.yml header: the instrumented spec suite "added minutes of instrumentation overhead to every main push … for a trend artifact that is consulted occasionally at best" — that is why it was moved off push; nothing reads the artifact since.
.github/workflows/engine-split-metric.yml header: "Report-only — no gate until a threshold is agreed (~88% at ADR time)"; ADR-0076 D7.
.github/workflows/showcase-smoke.yml header: "Manual + nightly only; it never gates PRs. Promote to a PR gate once it has proven stable here."
test-nightly-tiers.yml: the nightly e2e/live tiers; its report job files one issue per failing file (maintainer direction 2026-09-07 「测试会不会太多，是否都是必要的」).
AGENTS.md Prime Directive 14: .github/workflows/** is Tier H.

Premises (re-check)

30-day run history on main (GET /actions/workflows/{id}/runs): Spec Coverage 29 success / 1 failure; Engine Split Metric 5 success; Showcase Smoke 22 success / 8 failure (the failing step: "Vendor the pinned Console SPA"), last six green. None of the three writes an issue (grep -c "issues" <file> → 0 write paths).
No card in the 600 newest issues cites a coverage trend, the engine split ratio, or a showcase-smoke red.

Options × cost × effort

	What	Consequence	Effort
A retire all three	delete three workflow files, their `check:*` wiring and `scripts/ci/scheduled-full-run.mjs`'s knowledge of them if any	the showcase nav-surface render assertion is no longer run anywhere nightly; `Build & E2E UI` covers the Console build on PRs, not every showcase surface	devx · 1 Tier H PR · XS
B retire two, fold the third	as A for Spec Coverage and Engine Split Metric; Showcase Smoke's assertion becomes a `.live.test.` under the nightly tiers so a red files a card	the assertion keeps running with a reader; one nightly job fewer	devx · 1 Tier H PR + one test move · S
C keep	nothing	three jobs keep running unread	none

业务含义

A：没人看的仪表盘拆掉；B：拆两块，第三块的指针接到会响的那块表上；C：维持现状。

os-decision-facets

① 项目长远合理性：没有读者的检查不是检查；B 把唯一还有断言价值的那条接到有读者的夜跑上，缩小工作流数量而不丢断言。
② 实际业务拉动：三条工作流 30 天 0 张卡、0 个读者；Showcase Smoke 8 次红无人处理。
③ 防 AI 犯错：B 下 showcase 面渲染失败会开卡（响亮）；今天是静默红。
④ 创业阶段不扩散：remove 优于 declare-and-maintain；A/B 都减文件，C 保留三份永久义务。
Prior rulings read: coverage nightly · engine split · showcase smoke → ADR-0076 D7; maintainer 2026-09-07 「测试会不会太多」; thread: none.

devx 席开一个 Tier H PR（删两条或三条工作流 + 搬断言），由你批准落地；本卡随 PR 关闭。

Brief-claimed-by: session_01KrKXQVvgYk2AJ4VkqMobyb · batch #407 · 2026-10-27T04:02Z

Director seat, summon #51 continuation (ledger objectstack#12708). Filed by this seat on the maintainer's 「同意」 to the check-retirement sweep (record 6433263738) and presented in batch #407 as item 1 of 1. The card carries the six items and the facets block; seat increment at filing:

Run history re-read 2026-10-27T04:02Z on main: Spec Coverage 29 green / 1 red in 30 days, Engine Split Metric 5 / 0, Showcase Smoke 22 / 8 with the last six green; none of the three files an issue or is read by a script or a card (600 newest issues grepped).
The seat recommends B: retire Spec Coverage and Engine Split Metric; move Showcase Smoke's nav-surface render assertion under Nightly Tiers (*.live.test.*), whose report job files a card per red file, so the one assertion with product value keeps a reader. Not A (loses the only nightly check that renders every showcase surface) and not C. Workload: devx · 1 Tier H PR (.github/workflows/**, lands by the maintainer's approval) · S.
Prior rulings read: coverage nightly · engine split · showcase smoke → ADR-0076 D7; maintainer 2026-09-07 「测试会不会太多」; thread: none.

Ruling: batch #407 item 1 · letter B · maintainer 「同意」 2026-10-27T04:31Z

Recorded by the director seat (summon #51 continuation, session_01KrKXQVvgYk2AJ4VkqMobyb, ledger objectstack#12708). The maintainer answered batch #407 with 「同意」 — the seat letter. Brief 6433433659. Letter B: retire .github/workflows/coverage-nightly.yml (Spec Coverage) and .github/workflows/engine-split-metric.yml (Engine Split Metric, ADR-0076 D7 report-only) — the workflow files, their check:* wiring and any reader of their artifacts; .github/workflows/showcase-smoke.yml is retired as a workflow and its nav-surface render assertion moves under Nightly Tiers as a *.live.test.* so that a red files a card through that job's report step. Not A (the showcase assertion would run nowhere) and not C.

Workload (card column): devx · one Tier H PR (.github/workflows/**, lands by the maintainer's approval) · S; the test move is measured on the PR (Playwright against the live stack, the shape Nightly Tiers already runs). ADR-0076 D7's metric script may stay in scripts/ unwired, or go with the workflow — the lane says which in the PR body; if it goes, the ADR gets a one-line note in a separate governed PR.

Execution: needs-user-decision → pm:queue in this act (domain:devx, p2, area:devpath). Ruling-ref: names this comment. Clause-②: no, Metadata-protocol: none.

File surface: delete .github/workflows/coverage-nightly.yml and .github/workflows/engine-split-metric.yml with their check:* wiring and any reader of their artifacts; retire .github/workflows/showcase-smoke.yml as a workflow and move its nav-surface render assertion under Nightly Tiers as a *.live.test.* (the shape test-nightly-tiers.yml already runs, so a red files a card through its report step); .github/dependabot.yml / roster / required-context / self-test pins that list the three workflows. ADR-0076 D7's metric script either stays unwired in scripts/ or goes, the PR body says which; an ADR note, if owed, is a separate governed PR (⛔ no docs/adr/** here). ⛔ No ci.yml, no ui/.github/**; a ui/ test path only if the moved assertion must live beside the showcase app, and then named in the report. ⛔ Tier H (.github/workflows/**): draft until a GOVERNED_APPROVERS approval; the dev neither readies nor arms auto-merge · Amended on the thread's hand-back (PR #26529): the moved assertion lives at examples/app-showcase/test/showcase-smoke.live.test.ts with examples/app-showcase/vitest.config.ts, playwright.config.ts and types/node-shim.d.ts; turbo.json (showcase#test inputs gain scripts/nightly-tiers.mjs and its .d.mts); the pins that counted the retired workflows: scripts/check-stall-guard-budget.mjs (battery 10 floor 13→12), scripts/pm/dispatch-gates.self-test.mjs (the engine-split live-tree case), docs/qa/platform-checklist/areas/platform-core.json (source path); comment pointers in half-state-patrol.yml and shard-timings-refresh.yml; scripts/check-engine-split-ratio.mjs stays unwired (its --self-test stays in lint.yml)

Thread-read: 6433804956

Premise: the three workflows exist on main with the 30-day histories the card measured and none writes an issue (the dev re-reads each file and greps every reader of their names and artifacts first)
Serial constraints cleared: no in-flight PR of this seat touches these three workflow files or test-nightly-tiers.yml

Released by devx seat 2 (#20163). PR #26529 (ruling B) merged as 5065db82 after os-zhuang's approval; its 15 files on main match the reviewed head 2094edeb line for line. On its PR run, the showcase smoke ran inside Nightly Tiers with 53 Playwright cases passed. Its first scheduled nightly on main is the next reading.
