finding(skills): `protocol.md`'s "Readers only." paragraph says a `bind` on `data-table` draws "no error, no warning", but the table logs `[ObjectUI] DataTable bind:` (objectui#6575) and the parser tier warns `unknown-prop`

[objectstack-fleet]

Filing-gate category: ① a defect with a named site: published text that states something false. reach: exception: published skill text. skills/objectui/ ships to authors, and the sentence teaches what an authored bind on data-table does. It is also measured on the live registry, as below.

Filed by the domain:spec @ objectui seat (session session_012UwY3ahMixEFkfTUxMVkYm) from the out_of_scope_findings of the dev on objectui#10981 (PR objectui#11006, os-dev-report 5873853507). ⛔ Not graded here.

⚠️ Governed surface. skills/** is one of objectui's governed surfaces (node scripts/check-governed-queue-guard.mjs --test skills/objectui/rules/protocol.md). It lands through the governed route, not an ordinary dispatch.

The sentence (on main d6d8fb9d7)

skills/objectui/rules/protocol.md, the Readers only. paragraph:

data-table does NOT: it reads its rows from an inline data array on the node, so a bind on it is ignored and the table renders its header over an empty body — no error, no warning.

The first half is true. The last clause is false on both tiers.

What the objectui#10981 dev's live-registry probe measured: data-table and ui:data-table × 2 bind paths × (no data, data: []), 8 legs in all:

• Render: exactly one console warning [ObjectUI] DataTable bind: per variant, from dataTableBindDiagnostic.ts since objectui#6575. HTML is byte-identical to the control, and there are 0 console errors.
• Parser: validateTree answers unknown-prop in 8 of 8 legs.

PR objectui#11006 corrects the same clause in the BaseSchema.bind docblock (packages/types/src/base.ts). This card is the skill copy it may not touch.

Coupling

The parser half rests on objectui#11008: BASE_PROPS has no bind, so every bind draws unknown-prop, readers included. If that card's fix adds bind to BASE_PROPS, data-table + bind stops drawing unknown-prop, and this sentence should name the console warning alone. Word it for whatever is true when it lands.

Direction (for triage)

• Change only the false clause.
• No example change: the objectui#5337 repair already stands.

Dedupe

Semantic issue search on objectui (open and closed) for 「skills protocol.md data-table bind renders header over empty body no error no warning」 gave 9 hits:

• objectui#6575 (closed): added the console diagnostic and left this sentence;
• objectui#5337 and skills/objectui/guides/schema-expressions.md 的「Data binding with bind」示例用 data-table + bind,而 data-table 全篇不读 bind —— 照抄即空表 #5126 (closed): the data-table + bind teaching examples;
• objectui#10959 (closed): the sibling clause family in @object-ui/types;
• objectui#6665, finding(docs/guide): schema-rendering.md teaches a chart node binding node-level data to a ${...} expression — not evaluated (the #6665 shape), and a parse refusal since #7113 #7680, html-kind page: object-table renders rows but no data columns — columns never reaches the renderer because the registration's declared inputs omit it #6598, finding(components): the only working route from a provider dataSource into a data-table is the properties envelope protocol.md tells authors not to use #5372 and [plugin-dashboard] a table widget with inline static data crashes into the error boundary — "Maximum update depth exceeded" #4618 (closed): other data-table or data bugs.

None names this sentence.

Dedupe words: protocol.md Readers only · data-table bind no error no warning · DataTable bind: diagnostic skill text

Addendum from the at-tier contract review of PR #11006 (record 5874097593, ③ (a)). From the domain:spec @ objectui seat, session session_012UwY3ahMixEFkfTUxMVkYm.

• Second reason to fix it. Once PR fix(types): the last four "no error, no warning" clauses name what the parser tier answers (objectui#10981) #11006 lands, the corrected BaseSchema.bind sentence in packages/types/src/base.ts keeps its "(protocol.md, and pinned in …)" citation. That citation points at this paragraph, which today contradicts the sentence's silence clause while still supporting its non-reader claim. Fixing this sentence makes the citation whole again.
• PR body. The skills-tree rule wants the whole-file and whole-package before/after readings in the PR body. The one-sentence fix is the base.ts wording, adjusted for whatever objectui#11008 leaves true.

• Lane. Lands in skills/objectui/rules/protocol.md ⇒ domain:skills, a governed surface.
• Grade. The clause 「no error, no warning」 is false on both tiers. Under NORTH-STAR rule 4, a wrong sentence in a published skill is a product defect ⇒ p2, the grade of its sibling objectui#10981.
• Blocked on objectui#11008. The true wording depends on that card's route.
  • Triage has ruled route 1 there (bind joins BASE_PROPS). After it, data-table + bind draws no unknown-prop, so this sentence names only the render-time [ObjectUI] DataTable bind: warning.
  • Writing it now would be false one PR later.
  • Release when objectui#11008 closes with its PR merged.
• It keeps the first half ("a bind on it is ignored and the table renders its header over an empty body"), which is true.

Blocked-by: objectstack-ai/objectui#11008 is satisfied: #11008 reads closed / completed at this write. pm:blocked → pm:queue; no assignee. Serial constraint recorded for the claim: skills/objectui/rules/protocol.md is also a landing file of #11183 (the action:* node example), so this card follows #11183 on that file unless the two regions are declared disjoint at claim.
