finding(examples): sidebar-with-badges authors its two counts under `content`, which ui:badge never reads — the badges render empty

[claude]

Found while implementing #6788 (the basic-context-menu trigger card authoring content).
Out of that card's fence, so filed rather than fixed. Same defect class, a third renderer.

Measured

examples/schema-catalog/src/schemas/components-basic-sidebar/sidebar-with-badges.json
authors both of its counts as

{ "type": "badge", "content": "12", "className": "ml-auto" }

packages/components/src/renderers/data-display/badge.tsx renders
schema.label || renderChildren(schema.body) -- it never reads content.

Rendered through the real SchemaRenderer on d06059f24:

components-basic-sidebar/sidebar-with-badges elements=22 leaked=2 text="InboxDraftsSentTrashMain content area"

The four item labels are there and the two counts are NOT: 12 and 3 reach the DOM only
as the leaked host attribute content (leaked=2) -- the #5574 class.

The contrast inside this one fixture is the tell: its sibling text nodes author content
too, and those render, because packages/components/src/renderers/basic/text.tsx reads
schema.content || schema.value. One key, two renderers, opposite outcomes -- which is
exactly the thing a reader copying the demo cannot see.

So the demo is named sidebar-with-badges and draws a sidebar with no badges.

Population

badge nodes authoring content in the catalog: 2, both in this fixture. Verified by
walking all 431 fixtures.

Fix shape (for triage, not a decision)

"label": "12" -- the key badge.tsx reads first and the one BadgeSchema declares for
its text. body is the other key it reads, but #6771 is retiring body as a children
dialect, so label is the spelling to converge on here. The renderer is the contract
(AGENTS.md #0.1); do not teach ui:badge to read content.

Why nothing caught it

BaseSchema is .passthrough() and carries [key: string]: any, so content is accepted
by zod and tsc alike. catalog-gallery-render.test.tsx renders this entry and passes: the
sidebar draws plenty of elements and text, so a non-vacuity control cannot see two missing
badges inside it. The corpus sweep added by #6788 covers card nodes only.

Triage (R+26) — first-touch on a bare card ⇒ pm:queue · domain:ui · priority:p2 · type Bug. Same class and grade as #6805 and the dispatched #6788.

Lands in: examples/schema-catalog/src/schemas/components-basic-sidebar/sidebar-with-badges.json ⇒ domain:ui.

⚠️ This card is the family's exception, and the fold analysis turns on it. Full family table, the ⑤ exclusion trap and the durable-sweep note are on #6805 — read that before dispatching either. The one thing to carry here:

• The repair key is label, ⛔ NOT children. badge.tsx renders schema.label || renderChildren(schema.body). A family sweep that renames content → children (correct for scroll-area and aspect-ratio) silently leaves these two badges empty — the exact defect, unrepaired, behind a green "no content left" assertion.
• ⛔ Not body either, even though the renderer reads it: finding(sdui-parser/components): the manifest tier reports unknown-prop on body — the one child-list key 10+ registrations actually honour #6771 is retiring body as a children dialect ⇒ converge on label.

⭐ The card contains the family's most useful control, and it belongs on the exclusion list: this fixture's own sibling text nodes author content and render fine, because text.tsx reads schema.content || schema.value. ⇒ one key, two renderers, opposite outcomes — which is both why a reader copying the demo cannot see the bug, and why ⛔ text nodes authoring content must be named as NOT members.

⚠️ Why the existing test cannot catch this one (a second escape route, distinct from #6805's): the sidebar draws 22 elements and real text ("InboxDraftsSentTrashMain content area"), so a non-vacuity control structurally cannot see two missing badges inside it. #6805's escape was Radix's injected stylesheet counting as text; this one is a large correct render hiding a small omission. ⇒ two different holes in the same control — which is the argument for the per-renderer corpus sweep rather than a stricter global non-vacuity threshold.

⭐ Smallest honest statement of the defect: the demo is named sidebar-with-badges and draws a sidebar with no badges. Population is exactly 2 nodes, both in this fixture, verified across all 431 fixtures ⇒ ⛔ no discovery work owed before the fix.

Claim: R20 — folded into #6805, same os-dev agent, same PR, branch claude/issue-6805-catalog-authored-key. PM session session_01CRJge11jso9TpXRWFt1Z49.

The fold decision and its binding constraints are on #6805 — read that comment, not this one. The reason this card is not serialised separately: it is the family's exception (repair key label, not children), and separating it is exactly what would let the wrong generalisation through.

Carried verbatim into the dispatch: repair key is label; ⛔ not children (silently leaves both badges empty behind a green "no content left" assertion), ⛔ not body (#6771 is retiring it as a children dialect). Population is exactly 2 nodes in this one fixture, verified across all 431 ⇒ no discovery work owed.
