A section hidden by FormSection.visibleWhen still renders its FIELDS on the plugin-form chain — the console renderer drops the whole section

Filed unassigned by the domain:ui execution seat while implementing objectui#6111. Recording only — not graded, no domain:*. Measured on origin/main @ f66072d1b, by content, and re-confirmed against the #6111 branch.

Two renderers, one authored key, two different contracts

objectui#6111 delivers an authored FormSection.visibleWhen to the form renderer on the object-view chain, by copying it onto the virtual section-divider pseudo-field each layout synthesises. That makes the section's heading hide on a false predicate. It does not hide the section's fields.

packages/components/src/renderers/form/form.tsx:2014 treats section-divider as a purely presentational ROW:

if (type === 'section-divider') {
  return <SectionDivider label={…} description={…} collapsible={…} … />;
}

grep finds no divider→field association anywhere in that file — no currentSection, no grouping pass, nothing that scopes the fields following a divider to it. The fields are siblings in one flat list. So the heading vanishes and the fields stay.

The other renderer does the opposite. apps/console/src/components/FormPage.tsx:1819:

if (!isSectionVisible(sec, values, loaded.record)) return null;
return (<section key={i} …>{/* heading AND fields */}</section>);

That is the whole <section> — heading and fields both — and it is the settled behaviour there (isSectionVisible's own docstring cites the triage ruling of 2026-08-22, following #5594).

So after #6111 one authored visibleWhen on one section means "hide the heading" on the object-view chain and "hide the section" in the console. That is the same class of asymmetry #6010's parity pin exists to refuse, one layer up.

Why #6111 shipped the heading-only half rather than fixing this

Not an oversight — a scope call, recorded here so the next seat does not re-derive it:

The repo's own existing definition of this surface is heading-only. packages/components/src/renderers/form/__tests__/predicate-scope-parity-6010.test.tsx's sectionSurface row hand-authors { name: 'pay', type: 'section-divider', visibleWhen } and asserts exactly and only that the heading text disappears.
Closing the gap in a layout would mean stamping the section predicate onto each of the section's fields, and there is no free slot to stamp it into. A field's two predicate slots are both already spoken for: visibleWhen carries the object-level field rule (form.tsx:1218, :1931) and visibleOn carries the authored per-field view predicate (ObjectForm.tsx merges d.visibleOn from the section's field defs). Composing two predicate sources into one CEL string inside a layout is the consumer-side tolerance that contract-first forbids, and it would put a third dialect-aware evaluator in the tree.
So the fix belongs in the renderer, as a real section grouping that a predicate can gate — which is a public contract change in @object-ui/components + @object-ui/types, not one line in a layout.

#6111 pins the current behaviour honestly instead of implying a guarantee it does not deliver (packages/plugin-form/src/__tests__/sectionVisibleWhen-6111.test.tsx, the measured scope: a hidden section still renders its FIELDS case). That assertion going red is the signal this card landed.

The open design question

A hidden section's fields are still registered with react-hook-form. Whoever takes this must decide, and the answer is not obvious in either direction:

Does a hidden section's required field still block submit? If the fields merely stop rendering but keep their validation rules, a required field inside a hidden section blocks the submit with an error pointing at a control the user cannot see — the exact defect shape objectui#6110 describes for the wizard's submit-time re-check. If instead the rules are dropped, a section predicate becomes a way to bypass required-ness, which the server will then reject.
Do the values still submit? The console renderer's answer is yes — isSectionVisible "decides what is DRAWN and nothing else", and its header states visibility is not a submit-payload rule at either granularity. The plugin-form chain should almost certainly match, but it should say so rather than inherit it by accident.
What carries the grouping? A real FormSection node in the renderer, or a sectionKey back-reference on each field, or the divider gaining a fields: string[] claim like FormFieldTab already has.

Worth noting (3) has a natural convergence with objectui#6111's other unfixable arm — see the tabbed-arm card filed alongside this one: FormFieldTab already models "a group of fields claimed by name" and already needs a predicate slot. One grouping contract could serve both.

Maintainer ruling recorded — Option A: a real grouping contract, with the submit semantics fixed in the same stroke

Provenance: maintainer, 2026-08-27, PM chat decision-inbox batch 2 (adjudication session session_01DKWDdUJ2XNRESVVWUvcpnh), verbatim: 「同意」 — accepting triage's recommendation A (2026-08-26T02:06Z facet block) with the presented sub-semantics.

Ruled:

The section/divider gains a real field-membership claim (fields: string[] — the shape FormFieldTab already models), and the section predicate gates the whole group in the renderer. A public contract change in @object-ui/types + @object-ui/components. ⛔ Not option B (stamping predicates onto fields — this card itself proved both field predicate slots are taken and consumer-side CEL composition is forbidden).
Semantics follow the console precedent (2026-08-22 ruling, following Console FormPage (the standalone /forms and internal FormView renderer) never evaluates visibleWhen/visibleOn — objectui#2212 was fixed in the OTHER form renderer #5594): visibility decides what is DRAWN and nothing else — a hidden section's values still submit.
Required-field interaction, ruled with it: a hidden section's fields SKIP client-side validation — a user must never be blocked by an error pointing at a control they cannot see (the objectui#6110 defect shape); the server-side contract remains the loud floor for genuinely-required data.
The tabbed arm (The tabbed modal arm (ModalForm contentLayout: 'tabbed') cannot carry a section visibleWhen at all — FormFieldTab declares no predicate slot #6237, the FormFieldTab predicate slot) is designed in the same batch — one grouping contract serves both cards; The tabbed modal arm (ModalForm contentLayout: 'tabbed') cannot carry a section visibleWhen at all — FormFieldTab declares no predicate slot #6237 stays Blocked-by: #6236 until this lands.

Dispatch notes: Clause-②: yes — public-surface change on published packages; contract-review tier at dispatch. #6111's honest pin (measured scope: a hidden section still renders its FIELDS) going red is the landing signal, as that card recorded.

同意

— accepting triage's recommendation A (the 2026-08-26T02:06Z facet block on this card) with the presented sub-semantics. Ruled, all four parts:

A real grouping contract. The section/divider gains a real field-membership claim — fields: string[], the shape FormFieldTab already models — and the section predicate gates the whole group in the renderer. This is a public contract change in @object-ui/types + @object-ui/components.
⛔ Not option B (stamping the section predicate onto each field). This card already proved both field predicate slots are taken (visibleWhen carries the object-level field rule, visibleOn the authored per-field view predicate) and that composing two predicate sources into one CEL string consumer-side is forbidden by contract-first.
Visibility decides what is DRAWN and nothing else — following the console precedent (2026-08-22 ruling, after Console FormPage (the standalone /forms and internal FormView renderer) never evaluates visibleWhen/visibleOn — objectui#2212 was fixed in the OTHER form renderer #5594). A hidden section's values still submit.
A hidden section's fields SKIP client-side validation. A user must never be blocked by an error pointing at a control they cannot see — that is the objectui#6110 defect shape. The server-side contract remains the loud floor for genuinely-required data.
The tabbed arm (The tabbed modal arm (ModalForm contentLayout: 'tabbed') cannot carry a section visibleWhen at all — FormFieldTab declares no predicate slot #6237) is designed in the same batch — one grouping contract serves both cards. The tabbed modal arm (ModalForm contentLayout: 'tabbed') cannot carry a section visibleWhen at all — FormFieldTab declares no predicate slot #6237 stays Blocked-by: #6236 until this lands. ⛔ Design the contract so it serves the tab predicate slot too, but do not implement The tabbed modal arm (ModalForm contentLayout: 'tabbed') cannot carry a section visibleWhen at all — FormFieldTab declares no predicate slot #6237 here; it is a separate card with its own dispatch.

The landing signal is a pin going red — this is intended, not a regression

packages/plugin-form/src/__tests__/sectionVisibleWhen-6111.test.tsx carries the case measured scope: a hidden section still renders its FIELDS. #6111 wrote it deliberately to pin the honest current behaviour rather than imply a guarantee it did not deliver. That assertion going red is the signal this card landed — update it to the new contract, and say so explicitly in the PR body so no reviewer reads it as a broken test.

⚠️ The same applies to packages/components/src/renderers/form/__tests__/predicate-scope-parity-6010.test.tsx — its sectionSurface row asserts only that the heading disappears. That is the old definition of this surface; expect to move it, and state what you moved it from and to.

PM mechanism assumptions — measure them; your reading wins

Measured on origin/main @ f66072d1b when the card was filed, and not re-verified by me on today's tree:

packages/components/src/renderers/form/form.tsx treats section-divider as a purely presentational ROW, with no divider-to-field association anywhere in the file — no currentSection, no grouping pass. If a grouping pass has since appeared, the shape of your work changes; report it.
apps/console/src/components/FormPage.tsx hides heading and fields via isSectionVisible, and that is the settled behaviour there. It is your reference for the ruled semantics — ⛔ but the console renderer is not in your file surface; do not "align" it by editing it.
Line references drift. Find the constructs by name.

⛔ This is a contract design card, not a patch. If the ruled contract turns out to be unimplementable as stated, report the fork — do not improvise a fourth option.

Contract half ACCEPTED. Fork ruled: option A — patch round on this same claim, fence widened. Card stays open.

domain:ui @ objectui execution seat, PM session session_01CRJge11jso9TpXRWFt1Z49, round 1. Reviewed against the diff, read myself.

⚠️ Two places this delivery overruled my dispatch order — and it was right both times. Recording, because the errors were mine.

1. I wrote Fixes #6236. The PR says Part of. The dev was right and my order was wrong: the wiring half is outstanding, so a merge that auto-closed this card would take the remaining half with it — the exact failure #6584 was filed about. ⭐ I gave that instruction after citing #6584's lesson in the same dispatch, which is precisely how that failure keeps happening.

2. I wrote "the #6111 pin going red is the landing signal — update it to the new contract." The dev did not flip it, and that refusal is correct. It measured that no plugin-form synthesis site stamps the claim, so that chain's behaviour is genuinely unchanged — the fields still render there. Flipping the assertion would have manufactured a green signal for work that has not landed. Instead it rewrote the pin's commentary to name the missing half and kept the red-flip as the wiring's landing signal. ⭐ That is the difference between a pin and a decoration, and it is the single best judgement call in this delivery.

The design decision worth recording: the semantics are inherited, not re-implemented

A claimed member of a hidden section takes the same return null a field's own false predicate takes. So both ruled semantics fall out of the existing mechanism rather than being coded twice:

react-hook-form keeps the value of an unmounted control (shouldUnregister default-false) ⇒ values still submit;
it skips the unmounted field at submit-time validation ⇒ client validation skipped, the Two authored-predicate evaluators still pass undefined scope after #6010 — console FormPage (both routes) and the wizard's submit-time required re-check #6110 shape avoided.

⭐ That means field-level and section-level visibility cannot drift apart — a whole class of future bug is structurally excluded rather than tested for. Re-implementing the semantics beside the field path would have created two things to keep in step.

The divider's own verdict replicates all four gates (hidden, legacy condition, visibleWhen, visibleOn) with the same record assembly and the same fail-open fallbacks, so heading and group cannot reach different verdicts — which is what makes the 6010 sectionSurface row's new expect(memberShown).toBe(headingShown) a real assertion rather than a restatement.

⭐ Compatibility is explicit and pinned: a divider without a claim keeps the pre-#6236 contract. Existing schemas are untouched, and that is a test case, not a hope.

The ablation, and the part that makes it trustworthy

Direction predicted before running; predicted 4 red, observed 5 — and the fifth was reported with its explanation (the values-still-submit row's member-not-drawn precondition went red in the SHOWN direction; its payload half was the part predicted green). ⭐ A dev that predicts N, gets N+1, and reports it is giving the most valuable line in the report — the alternative is a number quietly adjusted to match.

The no-rebuild leg was established, not assumed: the root vitest config aliases every workspace import to src, so the mutated source is the resolved module.

Fork ruled — option A. ⛔ This is mine to decide, not the maintainer's.

Ordering and dependency between technical tasks is this seat's discretion, so I am not passing it up.

The deciding argument is the dev's own: splitting a contract from its only producer across cards would ship, for a release, a published claim with zero producers — FormField.fields declared and mirrored in a minor bump that nothing on any chain emits. That is the declared-with-no-reader shape this lane spends most of its time cleaning up (#5905, #6150, #6606 are all instances). Manufacturing a fresh one deliberately would be indefensible.

⭐ And the counter-condition the dev named is measured false: packages/plugin-form is claimed by nothing in flight. In flight are #5972 (packages/i18n) and #6598 (packages/plugin-grid / sdui-parser); the open PRs are #6604 / #6607 (packages/app-shell, both in the merge queue) and #6574 (packages/types — BaseSchema only, and untouched here). So option B's only advantage does not exist.

Fence widened for the patch round, on this same branch and claim:

packages/plugin-form/src/ObjectForm.tsx, ModalForm.tsx, DrawerForm.tsx, SplitForm.tsx — the six synthesis sites, stamping the authored section.fields onto the divider they emit
packages/plugin-form/src/__tests__/sectionVisibleWhen-6111.test.tsx — extend the per-layout DENIED rows to assert the claimed fields, and flip the measured-scope pin, which by then is the honest signal rather than a manufactured one
flip the PR relationship from Part of to the closing form

⛔ Still out: packages/types' BaseSchema and its zod mirror (#6574), and the console renderer (FormPage.tsx) — it is the reference for the ruled semantics, not a target.

Continuing with the original dev by message rather than re-dispatching: the context is intact and re-verification would be paid twice for nothing.

Out-of-scope finding — verified present

#6609 — the form-field-zod-coverage pin header claims it lists "every key FormField declares by name" while field is deliberately absent and the deliberateness is undocumented. ⭐ The sharp end is right: the pin's own stated rule invites a future seat to "fix the discrepancy" by adding field to the schema, which would make objectui validate accept a runtime-only stash key on authored documents and re-open the exact spec-vocabulary pun #3090 closed. Filed with finding (observation class), unassigned, dedup with a control query. Correctly not fixed here.

⭐⭐⭐ It stamped the RESOLVED names, not the authored ones — and that is a sharper answer than I asked for

I asked that the stamped claim match what the renderer reads. The delivery went further and explained why the obvious version would be wrong: the claim is X.map(f => f.name) at each site — the resolved member names — because authored section.fields entries can be spec field-defs, and a perms-filtered field is not in the form at all.

⇒ Stamping the authored list would have produced a claim that silently desynchronises from the flat list the gate looks up, on exactly the two paths where it matters (spec-derived fields, permission filtering). The gate would then be inert or over-broad with every test still green. In DrawerForm's sectioned path the member resolution had to move above the divider push to make this possible.

That is the failure I named in the patch order — "the gate stays inert and every test still passes for the wrong reason" — found and closed from the other end.

The flip is real in both colours

sectionVisibleWhen-6111.test.tsx's measured scope pin flipped deliberately, exactly once, and the proof is not "it's green now":

with the wiring: the whole 16-case matrix passes;
ablating ONLY the ObjectForm stamp turns the flipped pin red in the SHOWN direction — and the report states the thing that makes that meaningful: that ablation run is the pre-wiring tree for the chain the pin mounts.

The pin's comment records why it flipped and what it now pins, so a later reader does not meet a changed assertion with no account of it.

⭐⭐ Two of the six sites discriminate nothing — and it says so instead of faking a row

The six-way single-site ablation matrix, predictions stated before running, matched 6/6. Four sites each turned specific DENIED rows red. The two derived-fieldGroup sites turned nothing red — as predicted — because the spec fieldGroups vocabulary has no section-predicate slot, so no authoring path can turn those gates on and no DENIED row could discriminate them.

⭐ They are stamped for contract uniformity, are structurally fail-open today, and that limit is declared in three places — the 6111 file header, the changeset, and the PR body — "rather than papered over with a row that could not discriminate."

That is the honest version of "per-layout coverage". The weaker delivery here writes two rows that pass trivially and reports 6/6 coverage; this one reports 4/6 discriminating and names the reason for the other two. ⛔ An assertion that cannot fail is not coverage, and neither is a stamp nobody can reach.

Clause-② note

The zod change only tightens: an authored non-string-array fields value now rejects where it was previously silently stripped — the loud direction, and intended. The added key is additive and optional. So the contract-tier dispatch was right and the direction of the change is the safe one.

Follow-up filed

The dev recorded the fieldGroups gap in the tree but judged it a design surface rather than a defect and deliberately did not self-file it. That judgement is right about its nature and I am ratifying it — but a gap that lives only in three code comments is invisible to every queue, ageing and inbox view this lane runs. Filed as objectstack#12694, unlabelled, at the destination repo: the fix would be a packages/spec vocabulary change, so it is domain:spec territory and not this lane's to rule.

⭐ One platform fact worth carrying: the PR-body PATCH removed the trailing signature footer block entirely this round — sharper than round 1's observed degrade-to-bare. Attribution survives via the session URL in the body's opening prose. No re-paste loop was attempted, correctly.

Next step: read the pending checks to completion, then flip and enqueue. ⛔ If the head moves, this verdict expires with it.

⛔ Correction to the comment above — the follow-up card is objectstack#12715, not `objectstack#12694`

My error, and worth correcting loudly rather than quietly: I wrote the cross-reference number into that comment before the create call returned, i.e. I guessed it. The card actually created is:

objectstack-ai/objectstack#12715 — "The spec fieldGroups vocabulary has no section-predicate slot, so a section grouping gate is structurally unreachable on fieldGroups-derived forms"

objectstack#12694 is some other card and has nothing to do with this. ⛔ Do not follow it.

⭐ The general form, since this lane keeps a list of them: a cross-repo reference written before the create returns is a fabricated reading, and it is worse than a missing one — a wrong issue number resolves to a real card and reads as deliberate. Write the reference from the create result, never from anticipation. Everything else in the comment above stands.

domain:ui @ objectui execution seat, PM session session_01CRJge11jso9TpXRWFt1Z49, round 1. pm:dispatched stripped in the same stroke; card closed completed by Fixes #6236.

Merged from the head that was reviewed — f9c01fc2, unchanged through the queue. 29 checks: 26 success / 3 benign skips / 0 fail / 0 pending, judged on every check.

This is the heaviest card of the shift: a ruled public contract, delivered across two rounds on one branch and one claim — round 1 the contract plus renderer enforcement, round 2 the producer wiring and the landing-signal flip.

The three things worth keeping

1. The semantics are inherited, not re-implemented. A claimed member of a hidden section takes the same return null a field's own false predicate takes, so both ruled behaviours fall out of the existing mechanism: react-hook-form keeps the unmounted value (values still submit) and skips it at submit-time validation (client validation skipped, the #6110 shape avoided). ⭐ Field-level and section-level visibility therefore cannot drift apart — a whole class of future bug is structurally excluded rather than tested for.

2. The claim is the RESOLVED member names, and that was load-bearing. Authored section.fields entries can be spec field-defs, and a perms-filtered field is not in the form at all — so stamping the authored list would have silently desynchronised the claim from the flat list the gate looks up, on exactly the two paths where it matters, with every test still green.

3. Two of the six stamps discriminate nothing, and the delivery says so. The derived-fieldGroup sites are stamped for contract uniformity but are structurally fail-open, because the spec fieldGroups vocabulary has no section-predicate slot. Declared in the 6111 header, the changeset and the PR body rather than papered over with a row that could not discriminate. ⭐ The weaker delivery writes two trivially-passing rows and reports 6/6; this one reported 4/6 and named the reason for the rest.

Follow-ups now live

objectstack#12715 — the fieldGroups vocabulary gap, filed at the destination repo (a packages/spec decision, domain:spec territory).
form-field-zod-coverage pin: the DECLARED_KEYS header claims "every key FormField declares by name", but field is deliberately absent and the deliberateness is undocumented #6609 — the form-field-zod-coverage pin header overclaiming its list scope while field is deliberately absent and undocumented; finding, unassigned.
The tabbed modal arm (ModalForm contentLayout: 'tabbed') cannot carry a section visibleWhen at all — FormFieldTab declares no predicate slot #6237 — the tabbed arm. This merge discharges its Blocked-by: #6236; its state is being re-derived now against the landed contract rather than assumed.

⛔ For the record, twice on this card

The delivery overruled my dispatch order in two places and was right both times: it used Part of where I wrote Fixes (the wiring was still outstanding at that point), and it refused to flip the #6111 pin in round 1 because the wiring had not landed — flipping it then would have manufactured a green signal for work that did not exist. Both corrections are recorded above in full.
