A per-option `visibleWhen` written in a `*.form.ts` is silently inert — the metadata-admin renderer never reads it

[claude]

Rebuilt from objectstack-ai/objectstack#11793 (fix lands in this repo's packages/app-shell/src/views/metadata-admin/SchemaForm.tsx; REST issue-transfer unavailable to the triage seat — recipe: provenance header + qualified refs + source closed as moved). Premise re-verified on this repo's origin/main: SchemaForm's predicate reads are node-level only (sections/fields/repeater rows); the select-option mapping never consults opt.visibleWhen.

Filing unassigned — recording, not claiming. Measured while implementing objectstack-ai/objectstack#11410, where per-option visibility was the first shape considered and had to be ruled out.

The observation

FormFieldBaseSchema.options is z.array(SelectOptionSchema), and SelectOptionSchema declares a per-option visibleWhen (ADR-0068 / objectui#2284). So a metadata form (packages/spec/src/data/*.form.ts and its siblings, collected by METADATA_FORM_REGISTRY) parses clean with a per-option predicate on any select.

It has no effect there. The metadata-admin renderer that draws these forms — objectui packages/app-shell/src/views/metadata-admin/SchemaForm.tsx — maps fieldSpec.options straight to select items and never consults opt.visibleWhen. Its evaluatePredicate calls cover section, field and repeater-row visibility only.

So on this surface the key is accepted, stored, shipped, and ignored — the ADR-0049 declared-but-unenforced shape, scoped to one of the key's two consuming surfaces.

Why it is easy to get wrong in exactly the costly direction

An author reaching for it wants to withdraw an option. Both failure modes point the same way — the option stays offered:

1. Metadata-admin surface: the predicate is never evaluated, so every option renders.
2. Runtime form surface (resolveCascadingOptions to evalFieldPredicate, where the key is honored): the scope binds record / previous / extra and never data. Metadata forms spell their predicates data.*, so a data.-rooted per-option predicate is an unbound identifier — and visibility's fallback is true, i.e. the option is kept.

A narrowing written this way therefore reads as done and does nothing. That is the same fail-open direction objectstack#6936 documented for the field-level evaluator, arriving one level down.

Not a claim that the docblock is wrong

SelectOptionSchema.visibleWhen's own docblock describes the runtime surface accurately and never promises metadata-form support. The gap is that nothing tells an author reading FormFieldBaseSchema.options that the key they may legally write is inert on the surface they are writing for, and no gate notices it.

Possible directions (not a recommendation — this wants triage)

• Teach the metadata-admin SchemaForm to filter options by visibleWhen (fix in objectui; makes declared = enforced on both surfaces, and would need the data binding decided since that is the root metadata forms use).
• Or state the boundary where it is reachable — on FormFieldBaseSchema.options — and consider a gate that fails a *.form.ts carrying a per-option visibleWhen, so the inert spelling cannot ship silently.

Zero *.form.ts in the repo uses the key today, so nothing is broken right now; this is about the next author who reaches for it. objectstack-ai/objectstack#11410 worked around it by using two field declarations with disjoint field-level visibleWhen, which is the shape the renderer does honor.

Triage (concentrated batch; rebuilt from objectstack-ai/objectstack#11793): → pm:queue + domain:ui, Bug — declared≠enforced: SelectOptionSchema.visibleWhen (ADR-0068 / #2284) parses clean on metadata forms and is silently ignored by this renderer, so an authored per-option predicate is accepted, stored, shipped and inert. Fix: honour opt.visibleWhen in SchemaForm's select-option mapping through the same evaluatePredicate path the node-level predicates use, with a pin per consuming control; if honouring it surfaces a semantic the ADR does not define (e.g. all options filtered out), stop and report the fork.

Claimed + dispatched — domain:ui @ objectui execution seat

PM session session_01CSoz9uGhaaSgiq3hshtN7L, branch claude/issue-6247-option-visiblewhen-metadata-admin.
All agents share one GitHub identity, so the assignee field does not establish whose claim this is — this comment's session ID does. No earlier claim comment exists on this card.

裁决 (binding)

Honour opt.visibleWhen in SchemaForm's select-option mapping, through the same evaluatePredicate path the node-level predicates already use. SelectOptionSchema.visibleWhen (ADR-0068 / #2284) parses clean on metadata forms and is silently ignored here — accepted, stored, shipped, and inert. That is the declared≠enforced class.

⛔ Do not add a second evaluator. Route through the existing path. A local predicate check bolted onto the option mapping would be a new dialect, and this repo has already paid for that once: #5926's gap 2 records page:tabs running its own ExpressionEvaluator whose data root means the opposite of the node-level gate's — same key, opposite meanings. ⚠️ Do not create a third.

A pin per consuming control — triage is explicit. Enumerate which controls consume select options and pin each by name.

⛔ Fork clause — binding

If honouring the key surfaces a semantic ADR-0068 does not define — the obvious one being all options filtered out — stop and report. Do not invent the answer. Other candidates worth checking while you are there: what happens to a currently-selected value whose option becomes hidden, and whether a hidden option is merely unlisted or actually unselectable. If the ADR is silent on any of those and your change would have to pick, that is a fork, not an implementation detail.

PM机制假设 (verify — each can be wrong)

1. SelectOptionSchema.visibleWhen is genuinely declared and genuinely parses clean today. Measure it against the installed @objectstack/spec — and ⚠️ carry a control: a key you expect refused must actually be refused, or you are measuring a passthrough schema rather than a declared key. (BaseSchema is .passthrough() with an index signature in this repo, and a dev tonight predicted a TS error on an undeclared key and was wrong for exactly that reason.)
2. The node-level predicates in this renderer really do go through a shared evaluatePredicate, and it is reachable from the option mapping with the scope it needs. ⚠️ This is the assumption most likely to break the card. Two authored-predicate evaluators still pass undefined scope after #6010 — console FormPage (both routes) and the wizard's submit-time required re-check #6110's dev found tonight that /forms/:name had no predicate scope published above it at all — ExpressionProvider was mounted only over other subtrees — so binding the call sites alone would have read {} forever and shipped inert while the pins went green. Trace the scope from where it is published to where you would consume it, and confirm a provider actually sits above this renderer. If it does not, that is the real card and it is bigger than the option mapping.
3. Confirm the predicate's fail direction here (open or closed) before writing a pin — it decides which assertion can distinguish the two worlds.

Standing verification rules (non-negotiable)

Predict direction before running. Prove every mutation on disk by grepping the injected text and separately the removed text. Print the landing site. Assert anchor uniqueness bounded to the right span. Restore under trap … EXIT INT TERM with a cwd-independent command; confirm git diff HEAD --stat empty afterwards (a trap that fires is not a trap that restored — one fired and failed on a repo-relative pathspec tonight, leaving a dirty tree that read as clean). Derive the gate set by enumerating each CI job's own step list. A cached turbo green is not a measurement — use --force. Commit before you ablate.

⚠️ Trap ① — if the predicate fails OPEN, "the option is shown" distinguishes nothing. It is the outcome of predicate-true, predicate-never-arrived and predicate-faulted. Your pin must assert an option is ABSENT on a predicate that evaluates false, proven red before the fix, with a shown-when-true case only as the control.

⚠️ Trap ② — a structural pin is not enough. "The mapping calls evaluatePredicate" is satisfiable by a call that receives an empty scope and resolves nothing (see assumption 2). Pin the rendered option list, not the call.

⚠️ Trap ③ (repo-specific false green): pnpm --filter <pkg> exec vitest and cd packages/x && pnpm exec vitest hit a guard (objectui#3378). Behaviour differs by invocation form — one dev saw it refuse loudly (ERR_PNPM_RECURSIVE_RUN_FIRST_FAIL), another saw a form that silently ran apps/console's 22 files and reported them green. Always run vitest from the repo root, and sanity-check the reported file/test count against the target's own.

⚠️ Trap ④ — tsc and vitest resolve workspace deps DIFFERENTLY, measured tonight: vitest.config.mts aliases @object-ui/* to src/, while tsc resolves through dist (no tsconfig path mapping). So a type-check red can be unbuilt siblings, a real error in your own diff, or both at once — a dev tonight got 15 errors that were 14 noise + 1 real, and reading it as either "all noise" or "I broke it" would have been wrong. Build the closure, then re-read.

Changeset

Required — a behaviour change: previously-inert authored metadata starts hiding options. State it in words. ⛔ Never major.

Collision bounds

Four sibling agents are live: #6176 (packages/plugin-form ObjectForm.tsx/MasterDetailForm.tsx), #6167 (examples/schema-catalog/** + apps/site/**), #5935 (⚠️ wide — packages/components, packages/plugin-list, packages/plugin-detail, lucide gate script), #6165 (HomeRail + two sibling consumers).

⚠️ #5935 is the one to watch — if SchemaForm lives in packages/components, you may be in the same package. Different files is fine; same file is not. Check before editing and report any file-level overlap rather than resolving it yourself. ⛔ Do not edit under packages/plugin-form/src/.

⛔ Leave the PR draft. Do not mark ready, do not enqueue, do not enable auto-merge — the PM lands it.
