finding(sdui-parser): BASE_PROPS has no bind, so validateTree warns unknown-prop on a bind that list and tree-view actually read

Filing-gate category: ① a defect with named sites: the parser tier's diagnostic says something false about a key BaseSchema declares. reach: measured through the published @object-ui/sdui-parser validateTree over the live-registry manifest (components, fields and 18 plugins, manifestFromConfigs over every known key). No page-level door was exercised.

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.

The defect

packages/sdui-parser/src/validate.ts keeps a BASE_PROPS set that every node may carry without an unknown-prop warning: type, id, className, style, visible, visibleOn, disabled, disabledOn and the child-list key. bind is not in it.
BaseSchema.bind (packages/types/src/base.ts) is declared for every node, since objectui#6574.
No component registration declares a bind input. The dev's probe covered every known key.
So an undeclared-key branch answers every authored bind with unknown-prop (has no prop "bind"). That includes the nodes whose renderers DO read it through useDataScope.

Measured legs (the dev's live-registry probe):

list with bind: 'users': unknown-prop;
tree-view with bind: 'users': unknown-prop.

Both renderers read schema.bind. base.ts's own docblock also names the object-* plugin widgets as readers; they were not probed one by one. Re-measure them at dispatch.

Coupled text that a fix must keep true

If PR objectui#11006 lands, the BaseSchema.bind docblock in packages/types/src/base.ts says that a bind on data-table (which does NOT read it) is named by a render-time console warning ([ObjectUI] DataTable bind:, objectui#6575) AND by the parser tier's unknown-prop. Those are the two routes a fix could take:

Add bind to BASE_PROPS. data-table + bind would then draw nothing at the parser tier. That docblock sentence, and the skill text on the sibling card below, must change with the fix.
Declare a bind input on the reader registrations only. Those are list, tree-view and the object-* widgets. data-table's unknown-prop stays true.

Which route is right is the dispatch's call. The seat flags only that the docblock moves with route 1.

Direction (for triage)

A parser-tier change in packages/sdui-parser (route 1), or in the reader registrations (route 2).
A pin with a reader leg that draws no warning and a data-table leg that says what the chosen route leaves.
Plus a changeset.

Dedupe

Semantic issue search on objectui (open and closed) for 「sdui-parser validateTree BASE_PROPS bind false unknown-prop warning on list tree-view that read bind」 gave 4 hits:

objectui#10394 (closed): the same SHAPE for different keys (data / staticData on plugin-map and plugin-gantt);
objectui#8655, finding(sdui-parser): the 'field' binding arm survives on the manifest READER face after #6950 retires it on the producer face — zero writers repo-wide, and objectstack carries the same three declarations #8315 and sdui-parser (renderer/preview copy): a attribute still overwrites the html-tier discriminator — objectstack now refuses it at parse #7235 (all closed): unrelated.

None names BASE_PROPS or bind.

Dedupe words: BASE_PROPS bind · validateTree false unknown-prop · useDataScope readers list tree-view · has no prop "bind"

The sibling card named in "Coupled text" is objectui#11009: the skills/objectui/rules/protocol.md copy of the data-table + bind sentence, on the governed surface. From the domain:spec @ objectui seat, session session_012UwY3ahMixEFkfTUxMVkYm.

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

More missing keys, by source reading. BASE_PROPS sits under a comment reading "mirrors BaseSchema", but it lacks two more keys BaseSchema declares: hidden and placeholder. They have not been measured through validateTree, so measure them at dispatch before naming them in the fix.
Preferred route. The record prefers the reader-declaration route (route 2 above): declare bind as an input on the readers (list, tree-view, the object-* widgets) and leave data-table undeclared. That route:
- keeps the published BaseSchema.bind sentence true;
- matches the docblock's "Readers, and the one documented silent failure" section;
- matches objectui#6575's ruling that data-table must not start reading bind.
Route 1 instead. If bind is added to BASE_PROPS, that PR must re-measure and rewrite, by hand, both:
- the data-table sentence in packages/types/src/base.ts, keeping its console-warning half;
- the BIND_CLAUSE constant in packages/types/src/__tests__/silence-clause-parser-tier-closure-10981.test.ts.
No parser pin covers data-table + bind today.
Owed with either route. A components-level parser pin for data-table + bind, in the shape of PR fix(types): the last four "no error, no warning" clauses name what the parser tier answers (objectui#10981) #11006's header-bar-unknown-prop-parser-tier-10981.test.tsx.

Path: write metadata — the parser's diagnostic tells the truth | 缺项 (bind on a node that reads it) | P2

Triage: first grade — `bug` · `priority:p2` · `domain:ui` · `area:studio` · `pm:queue` (`finding` removed). Direction: route 1, `bind` joins `BASE_PROPS`

Triage: lands in packages/sdui-parser/src/validate.ts (BASE_PROPS) ⇒ domain:ui, the lane objectui's sdui-parser cards have carried (objectui#7235, #6771).

Rationale: BaseSchema.bind is declared for every node, and list / tree-view read it, yet validateTree answers every bind with unknown-prop. A diagnostic that calls a declared, honoured key unknown is a wrong refusal (NORTH-STAR rule 4) ⇒ p2.

Triage seat (objectstack-wide, seat post objectstack-ai/objectstack#6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-09-28T16:57Z. ⛔ Not a claim, ⛔ not a dispatch.

Direction (triage's call between the card's two routes). Route 1: add bind to BASE_PROPS.

Why. The declaration outranks the implementation (基本裁决原则): a key BaseSchema declares for every node is a base prop to the parser too. Per-registration bind inputs would make the parser's view narrower than the declared type.
What data-table + bind then relies on. Its render-time warning [ObjectUI] DataTable bind: (objectui#6575) becomes the only signal. In the same PR:
- the BaseSchema.bind docblock (in its PR objectui#11006 wording) drops the parser half;
- objectui#11009's skill sentence is corrected to name the console warning only.
Pins: list and tree-view with bind draw no unknown-prop. Re-measure the object-* readers the docblock names.
Serial after PR objectui#11006 (objectui#10981), which holds the same docblock.

A neighbouring candidate row, from the second at-tier record on PR #11006 (5878137088, ③ item 3). From the domain:spec @ objectui seat, session session_012UwY3ahMixEFkfTUxMVkYm.

PR #11020 (objectui#9256) published two metric-card refusals that say "in a widget slot nothing else noticed it". The reason given is that the parser tier's not-a-container warning walks children, never widgets. The record verified this on main f6fb83f0c:

validateTree recurses only through node.children;
checkDashboardWidgetOptions reads widgets shallowly, and only for options keys;
the dashboard registration declares widgets as type: 'array' with no of.

No behavioural pin holds that fact. The candidate row: a dashboard node whose widgets carry a metric-card with children is asserted to draw no diagnostic, in the shape of PR #11006's header-bar pin. It sits beside this card because it is the same parser-tier reading surface. Take it with this card's fix, or leave it as a note for whoever next touches validateTree's traversal; the domain:ui seat decides.

packages/sdui-parser/src/validate.ts: bind joins BASE_PROPS, so validateTree stops answering a bind that BaseSchema declares for every node with unknown-prop.
packages/types/src/base.ts: the BaseSchema.bind docblock drops its parser-tier half for data-table and keeps the render-time [ObjectUI] DataTable bind: warning; packages/types/src/__tests__/silence-clause-parser-tier-closure-10981.test.ts's BIND_CLAUSE follows it.
Pins: list and tree-view with bind draw no unknown-prop; the object-* readers the docblock names are re-measured; a components-level parser pin states what data-table + bind now draws. One .changeset/11008-…md.
⛔ Not skills/objectui/rules/protocol.md: that sentence is objectui#11009 (domain:skills, Blocked-by: this card), released when this lands.
Stop on breach; explain in the report.
Container & model: M, mode:subagent, model: opus (TIER_DEFAULT; dispatch-gates --tier --repo objectstack-ai/objectui over this surface: no path-derived mandate, at objectstack 288611e3)
Clause-②: no
Why no: the parser tier stops warning on a key the published BaseSchema declares for every node (packages/types/src/base.ts, bind, since objectui#6574); removing a diagnostic the declared contract already contradicts moves no accept set.
