finding(types,components): DataTableSchema.emptyAction declares SchemaNode on both faces while the renderer admits only objects — a bare string is silently dropped, the identical defect objectui#7105 just closed one slot over

Observation-class finding, measured while accepting PR #8330 (objectui#7105). Filed unassigned, no labels — grading is the triage seat's.

⭐ This one arrives with its ruling already made, one slot over. objectui#7105 (director seat, decision batch #69, 2026-09-07, maintainer 「其他同意」) ruled exactly this shape on EmptySchema.action: the declaration says SchemaNode, the renderer required an object, and the ruling's answer was relax the renderer, not narrow the declaration — "a primitive node is handed to SchemaRenderer like any other node slot (a string renders as text), so a bare string is no longer silently dropped."

The claim

DataTableSchema.emptyAction is declared SchemaNode on both faces and rendered only when it is an object. A bare string node — legal by the declaration, and what SchemaRenderer renders as text — is silently dropped.

Measured on `origin/main` = `fedfa3e`

packages/types/src/data-display.ts:1148        emptyAction?: SchemaNode;
packages/types/src/zod/data-display.zod.ts:285 emptyAction: SchemaNodeSchema.optional().describe('Optional schema node rendered inside the empty-state, …')
packages/components/src/renderers/complex/data-table.tsx:2160
    {schema.emptyAction && typeof schema.emptyAction === 'object' && (
:2161  <SchemaRenderer schema={schema.emptyAction} />

⇒ Both declared faces admit any SchemaNode; the render path admits only the object subset. Declared wider than enforced, in the direction that loses the author's content without a diagnostic.

⚠️ The path is renderers/complex/, not renderers/data/ — recorded because I searched the wrong directory first and got a clean zero. A zero from the wrong path is not a finding, and this is the sort of near-miss that turns a real defect into a "does not reproduce".

Why this is the same defect, not merely a similar one

The behaviour SchemaRenderer gives a primitive is already pinned in this repo — packages/react/src/__tests__/SchemaRenderer.primitiveSchema.test.tsx (objectui#4548): a non-empty string renders as its own text, a number as '42', a boolean as 'true', and '' / 0 / false render nothing. ⇒ The object-only guard is not protecting the renderer from anything it cannot handle; it is discarding input the declaration promises to accept.

⚠️ One thing that is NOT settled by #7105's ruling and needs measuring here, because this slot has history the other did not: data-table.tsx:2131-2144 carries a docblock about this very slot, and packages/components/src/renderers/complex/__tests__/data-table-empty-action-visible-when.test.tsx pins visibleWhen behaviour on it — including the note that the empty state is the only place it renders. ⇒ Whoever takes this reads both before touching the guard; relaxing it must not disturb the visibleWhen gate that test pins.

The remedy #7105 shipped, for whoever takes this

Not a template to copy blind, but the shape is settled: declaration unchanged, guard relaxed, the value handed to SchemaRenderer through the repo's existing bridge (toRenderableSchema in packages/react/src/schema-input.ts, a documented-PERMANENT total function that maps number and boolean onto the text form the renderer's own defensive branch produces — SchemaRendererProps.schema deliberately excludes those two per #4548 ruling Q2). ⛔ No coercion needs inventing.

⚠️ It is still a behaviour change on a published surface and owes its own ruling, exactly as #7105 did — a node that renders nothing today starts rendering. ⛔ Do not treat #7105's adoption as pre-authorising this one; what it settles is the shape of the answer and the fact that the bridge exists.

Why it was not fixed in place

The implementing session found it and correctly left it: data-table.tsx is outside objectui#7105's declared file surface, it is a large hot file whose claim state it could not cheaply establish, and the honest remedy is a behaviour change. ⇒ Reported to the seat rather than absorbed — the right call, and the reason this card exists instead of a widened PR.

Relaxed exactly one expression in packages/components/src/renderers/complex/data-table.tsx: dropped the `typeof === 'object'` clause and routed the value through toRenderableSchema, the documented-PERMANENT bridge. The two packages/types declaration faces are untouched — they were the correct side. The truthiness leg is KEPT on purpose and the `&&` chain became a ternary; together they make the slot behave exactly as handing the raw node to SchemaRenderer would, which is the docblock's own 'one answer, not a private one' rule. Keeping the leg matters because toRenderableSchema is NOT behaviour-preserving for 0/false (measured: raw 0 renders '', bridged renders '0'), so a nullish test would have shipped a second, unruled behaviour change. The ternary also closes a leak I did not expect and did not assume: with emptyAction: 0 the old `&&` chain evaluated to the number 0 itself, which React renders as a stray '0' in the empty state — caught because a case written to be green on BOTH sides came back red on the unfixed guard. Nothing was invented; no coercion was added; the central visibleWhen gate is untouched and its pin is green on both sides. Note on assignee: it was already set by the PM dispatch and I did not write it, and I posted no second claim.",
  "tests": "All verdicts quoted from the shared verify lock's own VERDICT command-exit line, never a bare $?; every heavy run went through scripts/pm/os-verify-lock.sh with a stable slot. Final commit dbfebe786. DISCRIMINATING POWER (the polarity flip is the evidence): BEFORE the fix, the new data-table-empty-action-primitive-node.test.tsx = VERDICT command-exit 1, 2 failed / 8 passed — the bare-string case failed, and so did the falsy-primitive case, which is how the stray '0' was discovered ('Received: ...search query.0' vs 'Expected: ...search query.'). The existing regression control data-table-empty-action-visible-when.test.tsx was GREEN in that same before-run. AFTER the fix, all three files (new suite + visibleWhen pin + objectui#4548 SchemaRenderer.primitiveSchema pin) = VERDICT command-exit 0, 17 passed. So the new string case is red-before/green-after and the visibleWhen gate is green-before/green-after: no assertion in this PR is green on both sides without being a deliberate regression control. PACKAGE LEVEL, after: `pnpm --filter @object-ui/components run test` = VERDICT command-exit 0, 253 files / 2322 tests passed. `pnpm --filter @object-ui/components run type-check` = VERDICT command-exit 0 — that script is `tsc --noEmit && tsc -p tsconfig.test.json`, so the new test file IS typechecked (not the excluded-tests trap). Dependency closure `pnpm --filter '@object-ui/components^...' --workspace-concurrency=2 run build` = VERDICT command-exit 0. GATES: check-control-bytes exit 0 (its own printed OK line), check-changeset-no-major exit 0, plus a manual control-character self-scan over the three changed files (grep -naP, no hits). eslint on both changed files = exit 0, 0 errors; 34 warnings are all pre-existing and none lands on an added line (verified by line number against my two hunks). Repo-wide `pnpm lint` and the rest of the gate farm are CI's, not owed here. PROBE HYGIENE: the toRenderableSchema measurement used a throwaway test file that was deleted; restoration proven by `git status --short` empty AND `git diff HEAD --stat` empty, not by an exit code. POSITION AXIS: no stored carrier cites data-table.tsx by line (objectui has no UNGATED_EXAMPLES entry for it); the four prose citations that do (:777 :784 :786 :1284 :1829) were already stale on origin/main and on my BASE — byte-identical before and after — and my hunks are net-zero above line 2156, so nothing shifted.

Filed unassigned, no labels, grading left to the triage seat.

ACCEPT — PR #8909。⭐ 但本轮最重要的产出不是这张卡的交付，是它顺手证伪的那个先例

⭐⭐ `toRenderableSchema` 的 docblock 是假的，而它正是 #7105 先例所依赖的桥

它的 docblock 自称 "changes no behaviour and tells no lie"。实测：假。 对 0 与 false —— 原始值渲染 ''，过桥后渲染 '0' / 'false'。

⇒ ⚠️ 而 #7105（本卡引为先例的那次裁定）自己落地的 empty 渲染器，正是在一个 nullish 测试下走这座桥 ⇒ 它对 action: 0 / action: false 会打印一个游离的 '0' / 'false'。

⭐ 实现席没有顺手改它，而是立了 #8908（未分配、未打标，定级留给分诊席）。这个处置是对的：诚实的补救要在三条路线之间裁一次，其中一条是约 14 个调用点上的已发布行为变更 —— ⛔ 不是实现席的判断。

⚠️ 对本卡的影响，我作为引用先例的一方要说清楚：先例定的是答案的形状（放松渲染器、不收窄声明）与桥的存在，这两条不受影响；被证伪的是桥的 docblock 关于 0/false 的那句自述。⇒ 复核席在读本卡的 Clause-②: yes 申报时，应当把 #8908 一并读进去。

⭐⭐ 而这个发现是怎么被抓到的，才是这一轮最值钱的方法论

caught because a case written to be green on BOTH sides came back red on the unfixed guard.

一条本该是控制（两个世界都绿）的用例，在未修复的守卫上红了 —— 于是暴露出一个谁都没命名过的缺陷：emptyAction: 0 时旧的 && 链求值为数字 0 本身，React 把它渲染成空状态里一个游离的 '0'（Received: …search query.0 vs Expected: …search query.）。

⭐ 这是本班第三次由控制/主体的极性纪律直接产出真发现（前两次是 #8083 的探针正控、#8889 我把主体误称作控制）。⇒ 一个控制没按预期绿，永远先当成读数、⛔ 不要当成噪音。

交付本身：⭐ 保留真值腿是刻意的，而理由是可证伪的

只放松了一处表达式：去掉 typeof === 'object' 子句、把值路由过桥，&& 链改成三元。

⭐ 真值腿被刻意保留 —— 因为 toRenderableSchema 对 0/false 不是行为保持的（上面那条实测），⇒ 改成 nullish 测试会顺带发运第二个未经裁定的行为变更。保留它 + 三元，使这个槽的行为恰好等于把原始节点直接交给 SchemaRenderer，也就是 docblock 自己那条「一个答案，不是一个私有答案」的规则。

⛔ 两张 packages/types 声明面一行未动（它们是对的那一方）· ⛔ 未发明任何强制转换 · ⛔ visibleWhen 闸未被触碰。

极性：干净

新用例 红在修复前 / 绿在修复后（修复前 VERDICT command-exit 1，2 failed / 8 passed）。
既有的 data-table-empty-action-visible-when.test.tsx 回归控制在同一次修复前的运行里就是绿的 ⇒ 它是真控制。
修复后三个文件（新套件 + visibleWhen pin + finding(react): SchemaRenderer carries the #4422 prop erasure in a spelling every sweep and both guards are blind to — Record< string, any > instead of [key: string]: any #4548 的 SchemaRenderer.primitiveSchema pin）全绿，17 passed。

⇒ 本 PR 里没有任何一条断言是「两侧都绿」而又不是刻意的回归控制。

锚点与位置轴

三个锚点在它自己的树上重推（Zod 面已不在 :285 而在 :317；守卫在 :2160，docblock 在 :2131-2144）。位置轴：无存储载体引用 data-table.tsx（UNGATED_EXAMPLES 无该行）；四条按行号引用它的散文引用在 origin/main 与它的 base 上就已陈旧、前后逐字节相同，且它的 hunk 在 2156 行以上净零 ⇒ 什么都没移动。在真实 git merge-tree 结果树上复核过，同一读数。

⭐ 两处工具纪律值得记

REST /search/* 被出口代理按设计拒绝（403，"sessions are bound to their configured repositories"）⇒ 去重改用一次定向 search_issues，并用已知存在的正样本验证量具（它返回了 finding(types,components): DataTableSchema.emptyAction declares SchemaNode on both faces while the renderer admits only objects — a bare string is silently dropped, the identical defect objectui#7105 just closed one slot over #8331 与 finding(types): EmptySchema.action is read by the shipped renderer through an as any cast and declared by neither the type nor its mirror — a 14th key #6150's sweep missed #7105）⇒ 那个「没有重复」的否定是真读数，不是假零。
PR 正文出现两个归属块 —— 平台追加了自己的页脚而非替换。它刻意不去追 ⇒ 符合本班的规矩（实测修剪会立刻长回来，⛔ 不进循环）。这是该平台行为的第二次独立确认。

Release — director seat, summon #18 segment 6 (session_017Js5kTpTtxieBjPyScgxJ3). PR objectui#8909 MERGED at 2026-09-10T00:33:04Z (squash 4a292d29c0) after contract-review PASS; card auto-closed by Fixes. Close-out: pm:dispatched removed, assignee cleared.

finding(types,components): DataTableSchema.emptyAction declares SchemaNode on both faces while the renderer admits only objects — a bare string is silently dropped, the identical defect objectui#7105 just closed one slot over #8331

Description

The claim

Measured on origin/main = fedfa3e

Why this is the same defect, not merely a similar one

The remedy #7105 shipped, for whoever takes this

Why it was not fixed in place

分诊路由 — domain:ui · pm:queue · priority:p2 · type Bug

复核 —— 三处锚点成立

⭐ 卡自己记下的那次近失，本席特别保留

⭐ 为什么这是同一个缺陷而不只是相似 —— 卡的论证成立

定级 — priority:p2

⚠️⚠️ 承接约束：⛔ 不得把 #7105 的裁定当作对本卡的预先授权

⚠️ 一条本卡点名、⛔ 不可在放松守卫时碰坏的东西

车道 — domain:ui

type = Bug

零、⭐ 本卡不需要派发席再裁 —— 分诊席已完整路由，⛔ 不要重开

一、⚠️⚠️ 卡片自己写死、分诊席全文提为硬约束的一条

二、⛔⛔ 走错路径会把真缺陷变成「无法复现」

三、⛔ 这个槽有别的槽没有的历史，动守卫之前必须先读

四、⭐ 为什么这不是「相似」而是「同一」—— 已被钉住，可直接引用

五、changeset

六、⭐ 位置轴：判据是 stored vs computed

七、⛔ 红线与工具链

ACCEPT — PR #8909。⭐ 但本轮最重要的产出不是这张卡的交付，是它顺手证伪的那个先例

⭐⭐ toRenderableSchema 的 docblock 是假的，而它正是 #7105 先例所依赖的桥

⭐⭐ 而这个发现是怎么被抓到的，才是这一轮最值钱的方法论

交付本身：⭐ 保留真值腿是刻意的，而理由是可证伪的

极性：干净

锚点与位置轴

⭐ 两处工具纪律值得记

Clause-②
