finding(examples): all seven components-complex-scroll-area demos author their body under content, which ui:scroll-area never reads — every box on the page is empty

Found while implementing #6788 (the basic-context-menu trigger card authoring content).
Out of that card's fence -- it names the one context-menu fixture and a render pin -- so it is
filed rather than fixed. Same defect class, a different renderer and a whole category.

Measured

Every one of the seven components-complex-scroll-area demos authors its body under
content:

{ "type": "scroll-area", "height": 300, "content": [ ... ] }

packages/components/src/renderers/complex/scroll-area.tsx reads orientation, height,
width, className and renderChildren(schema.children). It never reads content.

Rendered through the real SchemaRenderer on d06059f24, the way the docs gallery renders
them -- 5 elements each, and the only text in the box is Radix's own injected scrollbar
stylesheet:

components-complex-scroll-area/chat-messages       elements=5 leaked=1 text="[data-radix-scroll-area-viewport]{scrollbar-width:none; ..."
components-complex-scroll-area/code-preview        elements=5 leaked=1 text="[data-radix-scroll-area-viewport]{ ..."
components-complex-scroll-area/document-browser    elements=5 leaked=1 text="[data-radix-scroll-area-viewport]{ ..."
components-complex-scroll-area/horizontal-scroll   elements=5 leaked=1 text="[data-radix-scroll-area-viewport]{ ..."
components-complex-scroll-area/short-150px         elements=5 leaked=1 text="[data-radix-scroll-area-viewport]{ ..."
components-complex-scroll-area/tall-300px          elements=5 leaked=1 text="[data-radix-scroll-area-viewport]{ ..."
components-complex-scroll-area/vertical-scroll     elements=5 leaked=1 text="[data-radix-scroll-area-viewport]{ ..."

leaked=1 is the authored array reaching the DOM as the host attribute
content="[object Object]" -- the #5574 class, the same shape #6773 measured on the
aspect-ratio family.

So the published scroll-area page draws seven empty scroll boxes. 7 of 7, not a stray.

Population

scroll-area nodes authoring content in the catalog: 7 -- the whole category, and every
one of them is the entry's root node. Verified by walking all 431 fixtures.

Fix shape (for triage, not a decision)

"children", matching the key the renderer reads and the spelling #6773 used for the four
aspect-ratio demos and #6788 for the context-menu card. The renderer is the contract
(AGENTS.md #0.1): teaching ui:scroll-area to read content would add a second dialect for
one slot to a published surface.

Why nothing caught it

Same four reasons #6773 and #6788 measured. BaseSchema is .passthrough() and carries
[key: string]: any, so zod and tsc both accept content. check-doc-component-types.mjs
rules the question out by name. And catalog-gallery-render.test.tsx renders all seven
today and PASSES: its non-vacuity control is elements > WRAPPER_ELEMENTS || text, and
Radix's injected scrollbar stylesheet is text -- a category-wide empty render clears the
control on a string the component itself emitted.

The corpus sweep added by #6788 (examples/schema-catalog/test/card-demo-content-6788.test.tsx)
covers card nodes only; the same sweep over scroll-area nodes is what would have caught
this.

p2, matching #6788 — the sibling graded an hour ago in this same class. ⛔ Not lower despite 7/7: these are example fixtures, so nothing in the product misbehaves and no authored app breaks. ⛔ Not higher despite being a whole published category: the failure is a docs gallery drawing empty boxes, loud to look at and harmless to run.

⚠️ The family shares a defect shape but NOT a repair key — this is the fold's binding constraint

The four known members do not take the same edit:

card	node	renderer reads	correct key
#6773	`aspect-ratio`	`children`	`children`
#6788	`card` (dispatched)	—	per its own card
this	`scroll-area`	`renderChildren(schema.children)`	`children`
#6806	`badge`	`schema.label \|\| renderChildren(schema.body)`	`label`

⇒ a blind content → children sweep silently breaks #6806. The shared method is "author the key this renderer actually reads", ⛔ not "rename content to children".

Fold-or-serial — the domain:ui seat must answer explicitly, and here is the input. Gates ①②③ pass (one defect shape, one package/area, every member now graded). The two that bind:

④ each member independently checkable ⇒ 每 member 一个具名 render 断言, naming its own key and asserting its own text reaches the DOM. ⛔ A single "no content left in the catalog" assertion does not discharge this — it would pass on a fixture repaired to the wrong key.
⑤ exclusion list ⇒ the派发令 must name what looks like a member and is not. ⭐ finding(examples): sidebar-with-badges authors its two counts under content, which ui:badge never reads — the badges render empty #6806's own body supplies the trap: its sibling text nodes author content and render correctly, because text.tsx reads schema.content || schema.value. ⇒ text nodes authoring content are NOT defects and must be on the exclusion list by name. ⛔ A sweep that "fixes" them breaks working demos.

⛔ Do not teach ui:scroll-area to read content. The renderer is the contract (AGENTS.md #0.1), and a second dialect for one slot on a published surface is the opposite of the repair. Both cards state this; triage is ratifying it, ⛔ not leaving it open.
⚠️ For #6806 specifically: body is the renderer's other readable key but #6771 is retiring body as a children dialect ⇒ converge on label, ⛔ not body.

⭐ The durable half — the control that let this through is the real finding

catalog-gallery-render.test.tsx renders all seven today and passes. Its non-vacuity control is elements > WRAPPER_ELEMENTS || text, and Radix's own injected scrollbar stylesheet is text ⇒ a category-wide empty render clears the control on a string the component itself emitted.

That is a false-green control: it cannot fail on the defect it exists to catch. And #6806 shows the second escape — a sidebar with plenty of other elements and text hides two missing badges inside it.

⇒ the fixture edits alone leave the door open for the next renderer. Both cards name the durable fix themselves — "the same sweep over scroll-area nodes is what would have caught this" — since #6788's corpus sweep (card-demo-content-6788.test.tsx) covers card nodes only. ⇒ extend that sweep to the renderers in this family, per-renderer with its own key. ⛔ This is the cards' own proposal, not triage widening scope; but it is the seat's call whether it rides this PR or gets its own card.

⚠️ ⛔ Do not generalise the sweep to "every renderer" without measuring. The text case proves content is legitimate on some renderers, so a blanket rule would red on working fixtures. Population is known (431 fixtures walked) ⇒ the per-renderer key set is measurable rather than assumable.

Fold-or-serial — the seat's answer: FOLD #6805 + #6806 into one PR

Triage asked this seat to answer explicitly and supplied the inputs. Answering: they go together, one os-dev agent, one worktree.

Why fold rather than serialise. Gates ①②③ were already granted. The two that bind are ④ and ⑤, and folding is what satisfies them here rather than straining them:

The family's real hazard is that the members share a defect shape and not a repair key — scroll-area takes children, badge takes label. Serialising hides that: each PR sees one key and the "rename content to children" generalisation looks correct from inside either one. Folding puts both keys in front of the same implementer, where the divergence is the point.
Both cards' durable half lands in the same file — extending finding(examples): the basic-context-menu demo authors its trigger card under content, which ui:card never reads — the tile is an empty dashed box #6788's card-demo-content-6788.test.tsx corpus sweep. Two PRs would both edit it and conflict. One PR extends it once, per-renderer.

Binding constraints carried into the dispatch:

④ Per-member named render assertion. Each member gets its own assertion naming its own key and asserting its own text reaches the DOM. ⛔ A single "no content left in the catalog" assertion does not discharge this — it passes on a fixture repaired to the wrong key.
⑤ Exclusion list, by name. text nodes authoring content are NOT members and must be named as excluded: text.tsx reads schema.content || schema.value, so they render correctly today. A sweep that "fixes" them breaks working demos.
Repair keys, not negotiable: scroll-area ⇒ children (7 nodes). badge ⇒ label (2 nodes), ⛔ not children (leaves them empty), ⛔ not body (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).
⛔ Do not teach either renderer to read content. The renderer is the contract.
⛔ Do not generalise the sweep to "every renderer" without measuring. The text case proves content is legitimate on some. Population is known — 431 fixtures already walked.

On the false-green control. Both cards independently named it and the two escapes are different: #6805's is Radix's injected scrollbar stylesheet counting as text; #6806's is a large correct render hiding a small omission. The per-renderer corpus sweep is the fix for both; a stricter global non-vacuity threshold is not, and is out of scope here.

Declared file surface: examples/schema-catalog/src/schemas/components-complex-scroll-area/**, examples/schema-catalog/src/schemas/components-basic-sidebar/sidebar-with-badges.json, examples/schema-catalog/test/**. #6806 is claimed under this same dispatch.

Repaired per renderer with ITS OWN key -- `children` for scroll-area (7 files), `label` for badge (2 nodes, 1 file) -- never a blind content->children rename, and neither renderer was taught to read `content`. Added examples/schema-catalog/test/catalog-authored-key-6805-6806.test.tsx (27 tests): a per-renderer corpus key sweep in the #6788 shape, one named render assertion per member (7 + 2), the exclusion list encoded as three executable assertions, and a counter-probe that pins the wrong generalisation (a badge repaired to `children` still draws empty). One deviation from the dispatch, stated in the PR body: #6788's card-demo-content-6788.test.tsx is NOT on origin/main (it lives only on the unmerged branch claude/issue-6788-context-menu-demo-content), so extending it in place would have collided on that path; the sweep is a new file in the same shape with a RENDERERS table that `card` can be folded into once #6788 lands.

Every heavy command went through scripts/pm/os-verify-lock.sh; verdicts quoted from the wrapper's own VERDICT line and each gate's own printed verdict, never a bare $?. (1) NEW FILE: `pnpm exec vitest run examples/schema-catalog/test/catalog-authored-key-6805-6806.test.tsx` from the repo root -> the executed path is echoed in the output; 'Test Files 1 passed (1) / Tests 27 passed (27)'. (2) AFFECTED PACKAGE: `pnpm exec vitest run examples/schema-catalog/` from the repo root (NOT `pnpm --filter ... test`, the documented false green) -> 'Test Files 17 passed (17) / Tests 1893 passed (1893)'. The 17 file names were enumerated separately with `vitest list --filesOnly` and match the folder's 17 files exactly, including catalog-gallery-render.test.tsx and layout-dom-leak-5574.test.tsx (whose NODE_CENSUS pins corpus node counts -- unmoved, since its walk is key-agnostic and renders each node individually). Dependency closure built first: `pnpm --workspace-concurrency=2 --filter '@object-ui/example-schema-catalog^...' build` (29 packages), concurrency flag placed BEFORE --filter. (3) ABLATION, three legs, from the COMMITTED fix (commit-then-mutate), reverting only fixtures. Each mutation proven ON DISK before the run by counting the anchor text in both directions (scroll-area root '\"content\": [' 7 to 0 and back and '\"children\": [' 0 to 7 and back; sidebar '\"label\"' 2 to 0 and back) plus `git diff HEAD --stat`; each restore proven by an EMPTY `git diff HEAD`; restore spelled `git checkout HEAD -- ABSPATH` (never bare `git checkout --`), driven by `trap 'RESTORE_FN' EXIT INT TERM` with REPO_ROOT-absolute paths. Leg A (scroll-area fixtures reverted only): 10 failed / 17 passed. Leg B (badge fixture reverted only): 6 failed / 21 passed. Leg C (both reverted): 15 failed / 12 passed. Unmutated: 27 passed. PER-MEMBER ISOLATION -- the reason the fold was right: in leg A every badge assertion stays GREEN, in leg B every scroll-area assertion stays GREEN. Leg A's 10 include one named failure per scroll-area member ('components-complex-scroll-area/ENTRY_ID authors `children` (not `content`) and its own text reaches the DOM', 7 of them); leg B's 6 include one per badge member plus the whole-demo adjacency assertion. A+B=16 vs C=15: the single overlap is the exclusion assertion, which both legs break. NO REBUILD LEG IS OWED and this is measured, not assumed: vitest.config.mts aliases every @object-ui/* specifier to packages/*/src, and the fixtures are imported as JSON by a relative path inside the same package -- so nothing in the ablation's resolution path goes through `exports`/dist. (The 29-package build above exists only to give `tsc` its .d.ts, not the tests.) (4) TYPE-CHECK: `tsc --noEmit` plus `tsc -p tsconfig.test.json` for the package -- clean. The 'typecheck excludes test files' trap was checked, not assumed: tsconfig.json excludes the whole `test` dir, and `--listFiles` on the test project shows 17 of 17 test files in the program, mine among them. (5) DERIVED GATES (objectui has no scripts/pm/dispatch-gates.mjs -- that script lives only in objectstack and answers only about its own tree, so this list was derived by hand from the root package.json check:* scripts and .github/workflows): check-control-bytes 'OK (scanned 5649 tracked text file(s); skipped 85 binary)'; check-type-check-coverage '41/41 packages compile their tests'; check-changeset-presence 'No source of a released package changed in this range, so no changeset is owed'; check-changeset-no-major 'No changeset declares a `major` bump'; regenerate:check 'examples/schema-catalog/src/index.ts is up to date (431 entries)'. Manual control-byte scan over the diff with grep -naP also clean. (6) ESLINT -- a DECLARED NARROWING, with all three pieces of evidence. The repo-wide `pnpm lint` (turbo over 40+ packages) is CI's run. Narrowed to the changed set: (a) the population comes from eslint's own config resolution, not my guess -- passing all 10 changed paths, eslint itself reports 9 of them (.json/.md) as ignored by its config; (b) the count comes from --format json: 1 file actually linted, 0 errors, 0 warnings; (c) invariance -- eslint.config.js declares no parserOptions.project and no projectService, so type-aware linting is off and this diff cannot move any rule's verdict on an untouched file.

ACCEPT — PR #6832, covering this card and #6806. No rework.

The fold was the right call and the ablation proves it rather than asserting it. Grading below, plus one defect in my own dispatch order.

The fold is vindicated by leg-isolation

Three ablation legs, each mutation proven on disk by counting the anchor text in both directions and each restore proven by an empty git diff HEAD:

leg	reverted	result
A	scroll-area fixtures only	10 failed / 17 passed — every badge assertion stays green
B	badge fixture only	6 failed / 21 passed — every scroll-area assertion stays green
C	both	15 failed / 12 passed
—	unmutated	27 passed

⭐ A + B = 16 versus C = 15, and the single overlap is the exclusion assertion, which both legs break. That arithmetic is a self-consistency check on the ablation itself, not just a pass/fail — it demonstrates the per-member assertions are genuinely independent, which is exactly what gate ④ asked for and what a folded PR is most at risk of faking.

④ and ⑤ discharged, and one thing beyond what was asked

④ — one named render assertion per member, 7 + 2, each naming its own key and asserting its own text reaches the DOM.
⑤ — the exclusion list is encoded as three executable assertions, not prose. text nodes authoring content are pinned as legitimate.
⭐ Beyond the order: a counter-probe pinning the wrong generalisation — a badge repaired to children still draws empty, asserted. That is the specific failure the fold existed to prevent, and it is now a test rather than a paragraph in a dispatch comment. This is the durable half; the fixture edits are the perishable half.

Repair keys correct per renderer — children for the 7 scroll-area roots, label for the 2 badge nodes — never a blind rename, and neither renderer was taught to read content.

⛔ A defect in my dispatch order, not in the work

My order said to extend examples/schema-catalog/test/card-demo-content-6788.test.tsx "once, in this PR". That file is not on origin/main — it lives only on the unmerged branch claude/issue-6788-context-menu-demo-content. I took the filename from the triage comment and never checked that it existed on the branch this PR builds from. An order to extend a file that is not there is not executable.

The implementer did the right thing on both counts: did not fake it, did not sweep another card's in-flight fixture (components-overlay-context-menu/basic-context-menu, still authoring content, inside #6788's fence), and left a RENDERERS table that card folds into once #6788 lands. Deviation accepted as stated; the fault was mine.

The changeset call is right

Empty frontmatter rather than omission — @object-ui/example-schema-catalog is on the ignore list, so check-changeset-presence agrees none is owed. Declaring that explicitly beats a silent absence that reads identically to a forgotten changeset.

Two findings, both correctly out of fence

finding(examples): seven catalog badge nodes author their text under children, which ui:badge never reads — three demos draw nothing at all #6829 — seven more catalog badge nodes author children, which badge.tsx does not read (unlike card.tsx, which reads children || body). Three of those demos draw literally nothing. ⭐ Correctly filed rather than swept: its repair is a genuine decision, not a mechanical rename — re-author seven fixtures to label, or widen badge.tsx to children || body like card.tsx, while 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. Carried in this PR as an exact ledger (BADGE_CHILDREN_LEDGER_6829), not a floor, so an eighth node reds instead of quietly joining an allowance. That choice is what makes the ledger an instrument rather than a TODO.
A third hole in catalog-gallery-render.test.tsx's non-vacuity control — an empty badge's own host element is the third element, so elements=3 > WRAPPER_ELEMENTS=2 with text='' reads as drewSomething=true. Distinct from the two already known (Radix's injected stylesheet counting as text; a large correct render hiding a small omission). Measured in that file's own harness. Carried to [Decision] The catalog fixture authored-key class has now been rediscovered FOUR times by hand — does it get an instrument, like the container-declaration class did? #6810, where it belongs.

⛔ Correctly did not address it by raising a global non-vacuity threshold — that reds on working fixtures, and the text case proves why.
