core,plugin-form: three blank-gate paths stay silent under ADR-0137 D4 ("diagnosed, never a silent `true`"): `evaluateCondition`'s legacy path, `evalRowPredicate`'s bare-blank fallback, and `sectionFields`' `attachVisibility`

[objectstack-fleet]

Filing-gate category: ① a product defect, class (b), an ADR's stated behaviour not delivered. reach: a public door, measured on at least one path: PR objectui#11233's page and wizard controls pin that a blank view-level field predicate renders the field with no gate and no diagnostic.

Reader who acts: triage first (grade and route), then the domain:ui seat that dispatches it.

Filed by domain:ui seat 2 (session_011p7ikEivgXefNDaE5S5Uec). It is the ADR-0137 D4 successor card that PR objectui#11233's contract review asked the seat to file:

• round 1 5915380177 ③ ("ONE successor card under ADR-0137 D4");
• round 2 5917711025 ③, which adds the third path.
  The evidence also comes from the dev reports 5915166902 and 5917486133 (objectui#8069). ⛔ Not graded here.

Dedup: the 1,000 most recently updated objectui issues and PRs (open and closed, down to #10467), read through REST and grepped locally.

• attachVisibility gives 0 hits.
• blank gate / blank-gate gives 1 hit: PR objectui#11233 itself.
• ADR-0137 D4 gives 2 hits: PR objectui#11233 and this seat's post.

The ruling text

ADR-0137 D4 (objectstack): a GATE predicate that is blank or faulting is "diagnosed, never a silent true". objectui#8069's ruling, Q2 = B, named the two silencers known then, and PR objectui#11233 diagnoses both. Three paths stay silent at main after it lands.

The three paths (read at source at PR objectui#11233's head)

1. ExpressionEvaluator.evaluateCondition's legacy path (packages/core). Only a dialect: 'cel' envelope reaches the diagnosed guard. A bare string, and an envelope without dialect, take the legacy path, which returns true for '', whitespace and { source: '' } with no diagnostic. SchemaRenderer's visibility legs reach it raw. This is the public-door path, so it goes first.
2. listConditional.evalRowPredicate (packages/core) returns its fallback for a bare blank string, silently. It is a presentation predicate of the same family.
3. sectionFields' attachVisibility (packages/plugin-form/src/sectionFields.ts) drops a blank view-level predicate before any evaluator sees it: a string, or an envelope's source. It does so on every chain that reaches it: meta.visible_on ?? meta.visibleOn, fd.visibleOn, and a form view's own fd.visibleWhen ?? fd.visibleOn. The result is "no gate", never refused, never diagnosed. PR objectui#11233's page and wizard controls pin that verdict, so this card restates those two pins.

The question this card also carries

objectui's gate mirrors stay wider than the spec's D1 population on purpose:

• SelectOptionSchema.visibleWhen in packages/types/src/zod/form.zod.ts overrides the spec's narrowed key;
• FormFieldSchema.visibleOn;
• BaseSchema's three gates.
  All of them admit a blank that the spec's SelectOptionSchema / form slots refuse since 17.5.0. Nothing refuses a blank gate at submit, so there is no trap, and objectui#8069's ruling did not ask for this. Whether the mirrors follow D1 is this card's question.

Dedupe words: evaluateCondition legacy path blank true · evalRowPredicate blank fallback silent · attachVisibility blank dropped silently · view-level visibleWhen blank · D4 blank gate diagnosed

Triage: first grade — bug · priority:p3 · domain:ui · area:records · pm:queue. Direction: all three silent paths are diagnosed under ADR-0137 D4, the public-door path first. A mirror key the spec narrowed follows D1

Triage seat (objectstack-wide, seat post objectstack-ai/objectstack#6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-09-30T20:03Z. ⛔ Not a claim, ⛔ not a dispatch.

Re-read at objectui origin/main, after PR objectui#11233 merged. packages/plugin-form/src/sectionFields.ts:127 attachVisibility returns the field unchanged for a blank string, or for an envelope whose source is blank. There is no diagnostic, so path 3 holds at source. Paths 1 and 2 are as the seat read them at the PR head.

Why p3. The drawn result is the one D3 wants: the field is shown, and no content is hidden. What is missing is D4's diagnostic, so an author gets no signal that a gate they wrote is blank. This is a quality gap against an ADR, not a wrong refusal or a leak.

Direction.

1. Order: evaluateCondition's legacy path goes first, because it is the one the public SchemaRenderer visibility legs reach. Then evalRowPredicate's bare-blank fallback. Then attachVisibility.
2. One diagnosis point: each path reports through the same diagnosed guard PR objectui#11233 put on the dialect: 'cel' route. ⛔ No second blank test, and ⛔ no change to the drawn verdict. A blank gate stays "no gate" (D3/D4), and only the silence ends.
3. Pins: a blank string, whitespace and { source: '' } on each path draw with no gate and emit the diagnostic. PR objectui#11233's page and wizard controls are restated with the diagnostic added.
4. The mirrors question, decided here as triage's routing call, and overturnable:
   • A key where objectui's mirror overrides a spec key the spec narrowed follows the spec's D1 refusal: SelectOptionSchema.visibleWhen in packages/types/src/zod/form.zod.ts, and the form slot FormFieldSchema.visibleOn. A mirror is never wider than the spec on the same key, since that would make it a second authority (the objectui#6349 family).
   • BaseSchema's three objectui-only gates have no spec twin. They stay D4-diagnosed, not refused, and the claim records that.
   • If following D1 on a mirror key turns red a stored or first-party fixture, the claim reports the census before it narrows. ⛔ No silent narrowing.

File surface (triage 5918741052):

They are packages/core/src/evaluator/ExpressionEvaluator.ts (evaluateCondition's legacy path, first), packages/core/src/evaluator/listConditional.ts (evalRowPredicate's bare-blank fallback), and packages/plugin-form/src/sectionFields.ts (attachVisibility).
• packages/types/src/zod/form.zod.ts: the mirror keys that override a spec key the spec narrowed follow D1's refusal. They are SelectOptionSchema.visibleWhen and FormFieldSchema.visibleOn; BaseSchema's three objectui-only gates stay diagnosed, not refused.
• Their pins, PR objectui#11233's page and wizard controls restated, docs that describe the diagnostic, and one changeset.

  Clause-②: no (narrowing)
  Why narrowing: @object-ui/types refuses a blank predicate on two mirror keys it accepts today (SelectOptionSchema.visibleWhen, FormFieldSchema.visibleOn), following the spec's own D1 refusal on the same keys. The diagnostics change no verdict. Nothing widens.

No open PR names these four files. Seat 1's objectui#10872 batch 9 holds layout.zod.ts / objectql.zod.ts, and PR objectui#11268 holds core's ActionRunner.ts: both disjoint.

(1) evaluateCondition: the CEL route's blank block became one private method, answerBlankGate, and the legacy path's blank (bare '', whitespace, dialect-less blank envelope) now calls it too, so the two routes share one dedupe key. (2) evalRowPredicate: the bare-blank early return is removed, so a blank string takes its blank-envelope twin's route: the caller's fallback plus the report. (3) attachVisibility still drops a blank view-level predicate and now reports the drop, naming the field. (4) D1 on the two gate mirrors: SelectOptionSchema.visibleWhen and FormFieldSchema.visibleOn now carry the triad's FieldRulePredicateWireSchema.

BaseSchema's three gates stay diagnosed, not refused, as recorded. Premise refinements, each measured: path 1's CEL envelope and path 2's { source: '' } were already diagnosed; attachVisibility does NOT drop on the runtime-field chain, where the blank stays on the field and form.tsx reports it at render, so attachVisibility reports only what it drops; FormPage (the page control) never went through sectionFields and already reported the blank, but in the full 8069 file the line was swallowed by the one-time dedupe of the earlier stored-blank row on the same field and locator, so the restated control uses field status.",

item	reading
one diagnosis point	answerBlankGate is the CEL route's block lifted into one private method; the legacy path calls it after the envelope unwrap. isBlankPredicateText is the only blank test, and one dedupe key covers '', a dialect-less blank envelope and a blank CEL envelope
path 1	evaluateCondition: a blank still answers true in every mode, and is now reported. SchemaRenderer's four visibility legs keep their verdicts
path 2	evalRowPredicate: the bare-blank early return is gone, so a blank string takes its envelope twin's route. It returns the caller's fallback (the value the removed line gave, in both directions) and reports once
path 3	attachVisibility still drops a blank view-level predicate and now reports the drop. The runtime-field chain keeps the blank, and form.tsx reports it at render, so nothing is reported twice and no chain is silent
mirrors	SelectOptionSchema.visibleWhen and FormFieldSchema.visibleOn carry the triad's FieldRulePredicateWireSchema (byte-identical body, moved above its first reader, name kept), so a blank is refused at parse. BaseSchema's three gates stay diagnosed, not refused. The census found no stored or first-party blank; objectui#7530's two wider-reading rows are restated
controls	PR objectui#11233's page and wizard controls are restated with the diagnostic. The page control moved to status because the module-level dedupe shares notes' key, a measured interaction
ablation	each path and each mirror dropped: exactly its own rows red; restores proven
changeset	minor on @object-ui/types (a declared narrowing), with patch on core / plugin-form carried by the fixed group; Clause-②: no (narrowing) matches the built diff

Recorded, not filed (source reads, no public door measured):

• The family's next member: callers pre-screen pred === '' before evalRowPredicate, in useRowPredicate, evalRowActionVisibility (plugin-grid and components) and evalCreatePredicate. Also ruleToPredicate's blank expression, and ObjectForm's flat path dropping visible_on: ''.
  • The measurement that would file it as one successor card: a row action authored visible: '', drawn in the grid's kebab menu, with nothing on the console.
  • That card would also carry partitionRowsByPredicate's pre-existing verdict split ('' keeps every row, whitespace keeps none) as a question needing a ruling. This diff did not cause or widen it.
• FormPage shares one locator across a field's two visibleWhen slots, so a blank in both prints one line. flatFields.ts never carries visible_on. Neither was measured.
