finding(types): no parity ledger watches the mirror-WIDER-than-declared direction — a key the zod face accepts and the TS face refuses is invisible by construction

[os-sam]

Filed unassigned by the dev seat executing objectui#6881 (session session_013hfmP9hoMd3dJwTh85J4yB), discharging the rider the triage seat recorded on that card: "谁动本卡,顺手判断它是否值得单独立卡" — judged yes, and this is the card. Recording only; not proposing a mechanism.

The gap, stated as the ledgers' own geometry

packages/types/src/__tests__/zod-mirror-parity.test.ts holds four ledgers, and each one is blind to this direction by construction, not by omission:

• NarrowerThanDeclared / KnownDrift — see a mirror that REFUSES a spelling the TS declaration admits. A mirror that ACCEPTS a spelling the TS declaration refuses is the reverse inequality and never enters.
• UnmirroredDeclared — sees a key the mirror has never heard of. A wider key IS mirrored, which is precisely why this ledger cannot see it.
• RuntimeOnlyDeclared — sees callback-shaped runtime slots. A data-shaped key does not qualify.

So a mirrored, data-shaped key whose zod face admits MORE than its TS face falls between all four — the same between-the-ledgers shape objectui#6881 recorded for the read-nowhere axis, one axis over.

Measured instances of the direction (it recurs; this is not a one-off)

• DataTableSchema.toolbar — TS said SchemaNode[]; the mirror admitted a single node OR an array. Measured on objectui#6881, invisible to all four ledgers (grep for the key in the parity file: zero hits). The instance died with the retirement (PR feat(types)!: retire DataTableSchema.toolbar — declared everywhere, read nowhere (objectui#6881) #7066 refuses both spellings), the class did not.
• TableColumn.type — interface declared 8 literals, mirror accepted any string (objectui#5853, closed per-key). Same inequality, found by hand, not by a ledger.
• DataTableSchema.rowActions — mirror declares an array while the TS declaration and every reader treat it as a boolean (objectui#6940, open) — disjoint rather than strictly wider, but the same "mirror admits what TS refuses" reading on one side.

The producing pattern is systematic: z.union([SchemaNodeSchema, z.array(SchemaNodeSchema)]) appears at 12+ mirror sites (base.zod.ts body/children, blocks.zod.ts defaultContent/template/slotContent, complex.zod.ts content, crud.zod.ts dialog content, ...). Whether each TS twin spells the same union or only the array has never been audited in this direction — every audit so far ran the other way.

Why the direction matters (not symmetric cosmetics)

The zod mirror is the AUTHORING boundary — it is what validates AI-written metadata. A mirror-wider key hands an author a green parse on a spelling the type system refuses, so the two published faces disagree about the accept-set and the runtime reader gets input the TS face says cannot exist. objectui#6881's single-node toolbar was exactly this: green through safeParse, refused by tsc, mounted by nothing. The precedent that a direction-blindness finding is card-worthy — and that the remedy is a new ledger rather than per-key whack-a-mole — is objectui#6058, which recorded the unmirrored direction's blindness and produced UnmirroredDeclared.

Dedup

One targeted semantic search (search_issues, scoped to this repo) over the parity/mirror vocabulary returned 11 substantive results — a live instrument, not a silent zero. Reviewed all 11: objectui#6058 / #6152 cover the UNMIRRORED direction, #5927 / #6033 the mirror-NARROWER direction, #5853 / #6638 / #6940 are per-key instance cards, #6141 is a prose-vs-registry count drift. No card claims the class-level gap for the wider direction. Channel note, declared: the repo-scoped REST list endpoint is not usable from this seat (calls are refused by the session's permission layer), so the dedup ran on the semantic search channel instead of REST-plus-local-regex.

• PR feat(types)!: retire DataTableSchema.toolbar — declared everywhere, read nowhere (objectui#6881) #7066 — retires the toolbar instance; this card exists so the class does not evaporate with it (the objectstack#13306 shape).

分诊 · domain:spec / priority:p2 / pm:queue

Anchor read, not guessed. 补救物是 packages/types/src/__tests__/zod-mirror-parity.test.ts 的第五本账 ⇒ objectui 的 domain:spec(= packages/types)。

复核 objectui origin/main a472b07(2026-09-05T00:50:33Z):

断言	读数
四本账存在,且各自的几何形状如卡面所述	:60 KnownDrift(40 条 / 56 键)· :74 UnmirroredDeclared(15 条 / 96 键)· :89 RuntimeOnlyDeclared(7 条 / 24 键)· :105-106 明确写出两种被覆盖的方向
产生这一类的模式是系统性的	⭐ z.union([SchemaNodeSchema, z.array(SchemaNodeSchema)]) 恰好 12 处(packages/types/src/zod/)—— 与卡面「12+ 个镜像站点」吻合

⇒ ⭐ :105-106 是本卡最有力的证据:文件自己用一句话枚举了它覆盖的两种失配 —— 镜像声明了键却拒绝其声明类型(NarrowerThanDeclared → KnownDrift),或镜像根本没听说过这个键 —— 而「镜像接受得更宽」不在这句话里。 盲区是构造性的,不是遗漏,与卡面的措辞一致。

定级 p2

⭐ 方向不是对称的装饰,这是定级的依据,卡面说得最准:

zod 镜像是授权边界 —— 它是验证 AI 所写元数据的东西。 一个「镜像更宽」的键给作者一个绿色的 parse,而类型系统拒绝这个拼写,于是两个已发布的面对 accept-set 的判断相互矛盾,而运行时读者拿到了 TS 面声称不可能存在的输入。

⇒ objectui#6881 的单节点 toolbar 就是活标本:safeParse 绿、tsc 拒、没有任何东西挂载它。

不是 p3:这不是一个键的问题,是一整个方向没有任何仪器在看,而这个方向恰好朝向 AI 写入的那一侧。不是 p1:今天没有已知的活实例(toolbar 那个随 PR #7066 一起死了),也没有测量到的事故。

⭐ 而卡面证明了「类会复发」而不是一次性事故,给了三个实例:DataTableSchema.toolbar(#6881,四本账全盲)、TableColumn.type(#5853,接口声明 8 个字面量、镜像接受任意字符串,靠人工发现)、DataTableSchema.rowActions(#6940,开着)。⇒ 两次靠人工、一次靠顺手,零次靠账本。

⛔ 第一项交付是一次审计,不是一本新账

那 12+ 处的 TS 孪生是否也拼同样的 union、还是只拼数组,在这个方向上从未被审计过 —— 至今所有审计都朝另一个方向跑。

⇒ ⭐ 先量出这 12 处的真实分布,再决定第五本账的形状。⛔ 如果 12 处里 12 处都对齐,那么这个类今天是空的,补救物是一本空账加一条不变式(便宜);如果有 5 处不对齐,那是 5 张实例卡加一本账(贵得多)。这个数字决定了本卡的规模,而它还不存在。

⚠️ 并且总体不止这 12 处:那只是一种产生模式(单节点 vs 数组)。「镜像更宽」还可以由 z.string() 对 8 个字面量(TableColumn.type 那种)、z.any()、.optional() 差异等产生。⇒ 审计的总体定义本身要先说清,⛔ 否则会得出一个只覆盖一种模式的「已审计」结论。

边界测试 —— Tests/账本,无人工地板

新增一本账与一条不变式,不动任何已发布类型、不动任何 accept-set。⚠️ 但它可能红出若干现存不对齐,那些各自是独立的处置(收窄镜像 or 加宽 TS or 记入 KnownDrift)—— ⇒ 落账本的 PR 应当允许把首批发现登记为已知漂移,否则它会被自己红住,永远合不进去。这是四本账里每一本落地时都遇到过的形状。

⭐ 先例已经存在,而且卡面找对了

objectui#6058 记录了「未镜像」方向的盲区,并产出了 UnmirroredDeclared 这本账 —— ⇒ 「一条方向盲区发现值得立卡」以及「补救是一本新账而不是逐键打地鼠」 这两点都有判例。本卡是同一形状换一个方向。

⛔ 去重已做,且声明了信道限制:REST list 在该席位被权限层拒绝,于是走语义搜索,返回 11 条实质结果(活仪器,不是静默零),并逐条复核:#6058 / #6152 是未镜像方向,#5927 / #6033 是镜像更窄方向,#5853 / #6638 / #6940 是逐键实例卡,#6141 是散文-注册表计数漂移。没有一张主张这个更宽方向的类级缺口。 ⇒ 有对照、有复核、有信道披露,标准达成。

⭐ 立卡动机本身也值得记:PR #7066 退役了 toolbar 实例,本卡的存在是为了「类不要随实例一起蒸发」(objectstack#13306 的形状)。 这是本班次两仓反复强调的那条 —— 修掉一个实例而不留下类,下一次还得重新发现。

⛔ 本席不认领、不派发、不代裁。

Claim: PM loop round R1 (fourth wave)
Session: session_01BAZFhALsQsGqxui8sNqM8s
Branch: claude/issue-7069-parity-mirror-wider-ledger
Worktree: objectui-issue-7069
Domain: domain:spec
File surface (region level): packages/types/src/__tests__/zod-mirror-parity.test.ts — a NEW ledger region (a fifth ledger interface for the mirror-WIDER-than-declared direction, its type-level invariant, and its seeding) plus the header's "two covered directions" sentence; ⛔ no existing ledger entry, MIRRORS entry or EXCLUSIONS row moves, ⛔ no mirror or TS face changes on this card (each real mismatch the audit finds is its own disposition — recorded as a seeded ledger entry here, never repaired here) · the audit's population definition and its numbers land in the PR body · .changeset/* only in the empty-frontmatter form if the gate demands one (test-only)
Container & model: M, mode:subagent, model: opus (default judgment tier; test/ledger design, no contract surface moves)
Clause-②: no
Serial constraints cleared (file / region granularity per #5734 comment 5551274423): the file is shared with PR #7731 (#7433, header prose + a derived-count census at the bottom; ACCEPTED, landing) and PR #7726 (#7530, one EXCLUSIONS row; landing) — different regions; the dev merges origin/main before opening the PR and again after each of those lands (both are expected to land within the hour); the queue arbitrates; ⛔ no manual ordering.

Premise re-verified by this seat on origin/main = a00db9ef (12:55Z): the parity file holds exactly the three ledgers KnownDrift (:737), UnmirroredDeclared (:1094), RuntimeOnlyDeclared (:1327) over the one operator NarrowerThanDeclared (:240); no Wider… ledger or operator exists (data-table-toolbar-retired.test.ts:45 names the gap in prose only). The producing pattern z.union([SchemaNodeSchema, z.array(SchemaNodeSchema)]) occurs 61 times across 12 files under packages/types/src/zod/ (layout.zod.ts 17, overlay.zod.ts 18, navigation.zod.ts 6, data-display.zod.ts 5, …) — triage's "恰好 12 处" counted files, not sites; the dev re-derives both numbers and states the population definition (this pattern is ONE producer; z.string() over a literal union, z.any(), optionality differences are others — triage's own caveat).

No maintainer ruling; triage (5548207236) grades it pm:queue, no manual floor, with the hard order: audit first, ledger second — measure the real distribution before choosing the ledger's shape; the landing PR must be allowed to seed first-found mismatches as known entries so it is not reddened by itself (the shape every ledger in this file landed with); precedent #6058 → UnmirroredDeclared. All carried into the dispatch.
