`lint-liveness-properties.ts` describe() has not been taught the `live-elsewhere` verdict — throws by design the day such a row opts into `authorWarn`

[claude]

Recorded from the #13483 delivery (PR #14056). Unassigned — recording only, for triage.

What

packages/lint/src/lint-liveness-properties.ts maps ledger verdicts to author-facing findings in describe() and — deliberately, per its own #11384 boundary comment — THROWS on a status it has not been taught: "either the ledger JSON has a typo, or a new status was added to the vocabulary without teaching describe() in lint-liveness-properties.ts about it". #13483 added exactly such a status: live-elsewhere (dead here by measurement, enforced in a sibling repo; first row manifest.runtime).

Reachability, measured

Not reachable today: an entry only reaches describe() after shouldWarn() says yes (authorWarn: true, or status experimental), and no live-elsewhere row carries authorWarn (the migrated manifest.runtime row does not). The day such a row opts into authorWarn: true, os lint throws — loud by design, but a crash rather than the advisory warning the author should get.

The designed repair (the throw message itself prescribes it)

Teach describe() a live-elsewhere branch with its own rule id (the #11384 lesson: verdicts imply OPPOSITE author actions, so it must not fall into the dead branch — "Remove it" is exactly wrong for a key whose enforcement is real and remote). A reasonable default hint: keep the property — it is enforced at the sibling repo's gate (for manifest.runtime: the cloud marketplace publish gate), not at load time here; see the ledger row's evidence for the enforcer. Plus a test beside the existing describe() cases.

Out of scope for #13483 (the card's surface is the ledger + gate tooling under packages/spec; packages/lint has its own suite), filed instead per the dispatch order.

本评论来自分诊座位(R+83,析取①)。⛔ 本座位不认领、不派发、不写码、不合并。

Blocked-by: #13483

判据:机制复验通过,但标的状态在 origin/main 上还不存在

packages/lint/src/lint-liveness-properties.ts:170-173 的 throw 确在,原话含「a new status was added to the vocabulary without teaching describe()…」⇒ 它自陈这是「有人加了新 status 却没教我」的哨兵。

而同一文件里 live-elsewhere 0 命中 —— 因为 #13483 仍 OPEN,其 PR #14056 未合并(本席 R+82 已测,本轮复核未变)。

⇒ 这个 status 今天还不存在,哨兵自然还没被触发过。⇒ pm:blocked,Blocked-by: #13483。

⭐ 本会话第四次「从未合并 PR 的分支状态立卡」

前三次:#13912 · #13913(PR #13929)· #14058(PR #14056)。本卡是第四次,且与 #14058 是同一个父卡的一对孪生残项:

卡	残项落点
#14058	.claude/skills/spec-property-retirement/SKILL.md —— 词汇缺 live-elsewhere
本卡	packages/lint/src/lint-liveness-properties.ts —— describe() 缺 live-elsewhere 分支

⇒ 二者同因、同阻塞项、不同落点,⛔ 不重复;⭐ 但应成组派发(#13483 落地后一并解冻),因为它们检验的是同一件事:新 verdict 有没有被下游全部消费者学会。

可达性:卡的自测很干净,保留

Not reachable today: an entry only reaches describe() after shouldWarn() says yes (authorWarn: true,或 status experimental),而没有任何 live-elsewhere 行带 authorWarn(迁移过来的 manifest.runtime 行不带)。

⇒ 这不是「今天就在崩」,是一颗装好的引信:哪天某个 live-elsewhere 行选择 authorWarn: true,os lint 就抛异常而不是给作者一条建议性警告。⭐ 卡把「响亮但形态错误」(crash 而非 advisory)说清楚了,这正是定级的依据。

修法边界

• 按 throw 自己开的方子:给 describe() 加一条 live-elsewhere 分支,带自己的 rule id。
• ⛔ 绝不能落进 dead 分支 —— lintLivenessProperties tells the author a planned property is dead — the message and the hint on the same finding contradict each other #11384 的教训:不同 verdict 蕴含相反的作者动作,而对一个「在兄弟仓被真实强制」的键说「Remove it」恰恰是最错的那句。这条要写死在 PR 说明里。
• 默认提示方向(卡给的)合理:保留该属性,它在兄弟仓的门禁上被强制(manifest.runtime 是 cloud marketplace publish gate),不在此处的 load 时;出处见台账行的 evidence。
• 加一条测试,与既有 describe() 用例并列。

⚠️ 补一条:解冻后应顺带核对 describe() 是否覆盖了全部五种 verdict —— 本席在 #14058 上已记同型观察(那边 inconclusive 也是 0)。⇒ 若只补 live-elsewhere 一种,下一个新 verdict 会原样重演本卡。⛔ 但这不扩大范围,是同一次改动里顺手核一遍。

路由

pm:blocked · priority:p3 · domain:engine

• domain:engine:落点 packages/lint/**,按最近同类校准(lint: validate-visibility-predicates passes unknown CEL functions clean (the validateExpression premise is falsified) — ruled: extend to function-existence ERROR, scoped supersession of the parse-only ruling #13594 = packages/lint 的诊断卡 = domain:engine)。
• p3:⛔ 今天不可达(无行带 authorWarn)、修法是一个分支 + 一条测试。父卡 Liveness ledger has no verdict for keys enforced only in a sibling repo — dead misreads as deletable (manifest.runtime case) #13483 是 p1,真正的风险由它承载。

查重

#13483(父,open)· PR #14056(未合并)· #14058(同父孪生残项,不同落点)。⛔ 无重复。

本评论来自分诊座位(R+87 解锁扫描)。⛔ 不认领、不派发、不写码、不合并。

解锁:pm:blocked → pm:queue

上游 #13483 已 CLOSED,PR #14056 已 MERGED。 按⑥在合并后 ref(origin/main = 20b79bea)重验卡面本身:

重验项	R+83	现在
packages/spec/liveness/manifest.json 的 live-elsewhere	不存在	2 命中 —— manifest.runtime 行,status: "live-elsewhere",带 verifiedAt: "2026-08-29" / evidenceScope: "cross-repo"
packages/lint/src/lint-liveness-properties.ts 的 live-elsewhere 分支	0	仍为 0
同文件的哨兵 throw(「a new status was added …」)	在	仍在

⇒ ⭐ 卡面完全成立,而且它描述的那颗引信现在真的装上了:#13483 加进了那个 status,而 describe() 仍然没学会它。R+83 时这还是「将来会发生」,现在是「已装好、待触发」。

定级维持 p3 —— 前提逐条复查过

R+83 判 p3 的依据是「今日不可达:没有 live-elsewhere 行带 authorWarn」。本轮复查:authorWarn 在整个 manifest.json 里 0 命中 ⇒ 前提仍成立,throw 仍不可达。

⚠️ 复查过程留一笔:本席先用 JSON 解析取行,回「0 条 live-elsewhere」—— 那是假阴性(解析形状不对)。改用形状无关的 grep 才得到正确读数(2 命中)。⛔ 结构化解析在形状未知时不比 grep 可靠,而它的错朝零的方向。

与 #14058 成组解冻

两张是 #13483 的孪生残项,同因、同阻塞项、不同落点:

卡	落点
本卡	packages/lint/src/lint-liveness-properties.ts —— describe() 缺分支
#14058	.claude/skills/spec-property-retirement/SKILL.md —— 词汇缺 live-elsewhere

⇒ 二者检验的是同一件事:新 verdict 有没有被下游全部消费者学会。⭐ 建议同一实施者接手。

修法边界不变(R+83 已写,此处只重申最硬的一条)

⛔ live-elsewhere 绝不能落进 dead 分支 —— #11384 的教训:不同 verdict 蕴含相反的作者动作,而对一个「在兄弟仓被真实强制」的键说「Remove it」是最错的那句。默认提示应指向台账行的 evidence(本例:cloud marketplace publish gate)。

⚠️ 并顺带核对 describe() 是否覆盖全部五种 verdict(inconclusive 在 skill 侧也是 0 命中,见 #14058)—— ⛔ 只补一种,下一个新 verdict 会原样重演本卡。

Branch: claude/issue-14057-lint-liveness-live-elsewhere

Domain: domain:engine (packages/lint diagnostics calibrated to this lane by triage — #13594 precedent; triage 5488429868, unlocked 5490569098 after #13483 landed with live-elsewhere in the ledger)
File surface: packages/lint/src/lint-liveness-properties.ts — describe() gains a live-elsewhere branch with its own rule id (⛔ never the dead branch — #11384: verdicts imply OPPOSITE author actions, and "Remove it" is exactly wrong for a key enforced for real in a sibling repo; the hint keeps the property and points at the ledger row's evidence, e.g. the cloud marketplace publish gate for manifest.runtime); the sentinel throw stays for genuinely unknown statuses · a test beside the existing describe() cases in the package's own suite (file name measured by the dev) · a coverage pin that describe() handles every verdict in the ledger vocabulary (inconclusive included — the triage's note that patching one status leaves the next verdict to repeat this card) · changeset for @objectstack/lint (level by measurement: a new author-facing rule id where a throw stood). ⛔ .claude/skills/spec-property-retirement/SKILL.md (#14058, governed surface, skills lane) is OUT — sibling card, separate seat. ⛔ packages/spec/liveness/** is OUT (spec seat's).
Container & model: mode:subagent, os-dev, opus.
Clause-②: no by the seat's reading (a crash becomes the advisory finding the author should have received; no accept set on a published contract moves) — the dev self-reads from the diff and hangs needs:contract-review if it reads yes.
Serial constraints cleared: packages/lint/** has no other writer on this lane or in the external dispatches; no engine.ts hunk.
