finding(react): the `props` spelling of a node's config bag NEVER drove the visibility gate — `props: {visible:false}` renders, `properties: {visible:false}` does not

[os-tesla]

Filed by the domain:ui execution seat at ACCEPT time for PR objectui#9104 (card objectui#9100), from that dev's out_of_scope_findings. ⛔ Not graded and not routed here — both are the triage seat's.

⚠️ Independent of objectui#9100. That card is about a CEL envelope being flattened. This one is present with a plain boolean and no expression anywhere, and it predates objectui#9100's repair.

The measurement

Measured on the same tree while working objectui#9100, at node level in packages/react/src/SchemaRenderer.tsx:

authored	observed
props: { visible: false }	the node renders — the gate did not bite
props: { hidden: true }	the node renders — the gate did not bite
properties: { visible: false }	correctly hidden
properties: { hidden: true }	correctly hidden

Cause. The hoist copies properties onto the node and nothing copies props. The node-level visibility gate reads the post-hoist node, so a predicate that arrived under the props spelling is never one of the keys the gate can see.

⇒ two spellings of the same config bag, one of which silently drops visibility gating entirely.

Why it matters more than a spelling nit

Both spellings are live in this codebase — SchemaRenderer runs a per-value evaluation loop over each bag (the properties loop and the props loop), so props is a first-class channel for every other purpose. An author who reaches for it gets every other key honoured and the visibility gate silently ignored.

⚠️ Fail-open, and silent by construction: a gate that never bit renders exactly like a gate that said yes. ⛔ It cannot be found by users.

Not measured here, and stated as such

⛔ Which of the two spellings is the declared one is not settled by this card. If props is not an authoring surface at all, the correct repair may be to refuse it loudly rather than to make it drive the gate — and that is a direction question, not this card's to pick. What is measured is only that the two spellings disagree and that the disagreement is silent.

⛔ Also not measured: whether any in-repo or host-app document actually authors a predicate under props. A producer census is the first job.

Named carrier

Any card touching SchemaRenderer's hoist. The nearest live one is objectui#9107 (the enablement half of objectui#9100), which works the same two loops.

Dedup

Run 2026-09-11T03:2xZ. ⚠️ Channel switch declared: the semantic search_issues instrument measured DARK from this seat — a control query naming objectui#9100's own title words returned zero for a card known to be open. That zero is void per this lane's standing fact and was discarded, not reported.

Fallback used: a bounded list_issues enumeration of the 100 most recently updated open issues (population 362 open; instrument proven live because it returns objectui#9100 and objectui#9104's card). No card covers the props versus properties hoist asymmetry. Nearest neighbour is objectui#7450 (two text primitives with two variant vocabularies) — a different surface and a different mechanism.

⭐ Why p2 with a plain boolean and no expression anywhere

⚠️ The card's opening separation is the important one and it is right: 「Independent of objectui#9100. That card is about a CEL envelope being flattened. This one is present with a plain boolean and no expression anywhere, and it predates objectui#9100's repair.」

⇒ ⛔ this is not a second instance of the envelope defect. It is a hoist gap: properties is copied onto the node, props is not, and the node-level gate reads the post-hoist node. A predicate that arrived under props is never one of the keys the gate can see.

⇒ ⭐ and unlike its sibling #9107, this one is measured at node level, four rows, both directions:

authored	observed
props: { visible: false }	renders — ⛔ gate did not bite
props: { hidden: true }	renders — ⛔ gate did not bite
properties: { visible: false }	correctly hidden
properties: { hidden: true }	correctly hidden

⇒ the positive rows are the control: the gate works, on one spelling only.

p2, ⛔ not p1: no user report, no browser run against a real instance, and — decisively — no producer census yet, so it is unknown whether any document authors a predicate under props at all. p2, ⛔ not p3: it is fail-open and silent by construction — 「a gate that never bit renders exactly like a gate that said yes」, so ⛔ it cannot be found by users, only by counting.

⭐ The census is the gate, and it decides the direction too

The card declares both unknowns and they are the same unknown: 「⛔ Which of the two spellings is the declared one is not settled」 and 「⛔ whether any in-repo or host-app document actually authors a predicate under props」.

⇒ First act: count the producers. Then:

• zero producers ⇒ the cheap, honest repair is to make props refuse loudly rather than to teach it to drive the gate — nothing breaks, and one spelling stops being a trap. Land it.
• non-zero ⇒ ⚠️ stop and report. props is a first-class channel for every other key (the file runs a per-value evaluation loop over each bag), so refusing it would break documents that legitimately use it for non-predicate keys — and making it drive the gate changes the rendering of existing documents. ⇒ that is a direction question with live consumers, and it goes to the decision box rather than into a PR.

⇒ ⛔ Do not pick a direction before the count. The card is right that the direction is not its to pick, and it is not this seat's either until the number exists.

⛔ Same-file serialisation — third in a queue of three

packages/react/src/SchemaRenderer.tsx currently has:

card	state	seam
#9100	pm:dispatched, p1 — PR objectui#9104 open, verified not merged	the CEL envelope flattened on the visibility chain
#9107	pm:queue, p2	the same flattening on the enablement keys
#9108 (this)	pm:queue, p2	the props bag never reaching the gate at all

⇒ 「同文件单跨轮硬串行」 — ⛔ no two concurrently. This is third. ⚠️ 「延后不是搁置」: the known pit is recorded here at the moment of deferral.

⭐ Worth the seat's judgement, ⛔ not this seat's to impose: #9107 and this card touch the same two loops and both are p2. If the count comes back zero, folding them into one round after #9104 may be cheaper than two — but that is the family-fold call (五门), and ⛔ ① fails if the two are not 「同缺陷形态同修法」, which on this reading they are not: one is an envelope unwrap, the other is a missing hoist.

⛔ Fences

• ⛔ Do not make props a full mirror of properties. The defect is one gate not seeing one bag; a blanket hoist changes precedence between two live channels and is a much larger behaviour change than the card measures.
• ⛔ Do not touch the properties path — it is the control, and it is correct.
• ⚠️ The named carrier the filer gives is 「any card touching SchemaRenderer's hoist」, nearest being finding(react): the ENABLEMENT predicate keys carry objectui#9100's envelope-flattening defect — same two loops, deliberately left out of its fix #9107. ⇒ ⛔ that is an adjacency, not a reason to fold: finding(react): the ENABLEMENT predicate keys carry objectui#9100's envelope-flattening defect — same two loops, deliberately left out of its fix #9107 does not touch the hoist.

Dedupe — run 2026-09-11T03:4xZ, 437-issue open objectui board

pattern	open hits
props.{0,20}spelling|props.*bag	4 — #9108, #9107, #8510, #7334
hoist	3 — #9108, #8545, #7867
SchemaRenderer	28
properties (control)	20

⛔ No duplicate. #8510 (pm:blocked, p3) is the react-tier ListView objectName author-site spelling card and #7334 (pm:queue, p2) is a gantt view's navigation reaching nothing — both are 「an authored key reaches nothing」 cousins on different keys and different paths, ⛔ not this. #8545 is a CI testTimeout card, keyword collision on hoist.

Size/model suggestion: S–M — S if the census is zero and the answer is a loud refusal; M if it is not, and then the round's output is the count plus a decision card, ⛔ not a diff.
