spec: form-view predicates must loudly reject the `features.*` root — ruled vocabulary narrowing (from objectui#6262)

[os-zhuang]

Provenance: maintainer ruling 2026-08-27 (PM chat, decision-inbox batch 2, adjudication session session_01DKWDdUJ2XNRESVVWUvcpnh), verbatim: 「同意」 — adopting Option B on objectui#6262: form views may not name features.* in predicates; the exclusion is declared and enforced at authoring time with a loud rejection.

Why

One authored predicate text currently gets two verdicts: inside an app (/apps/:appName/*) the features.* scope root resolves against real auth-config flags; on the direct route /forms/:name the root is unbound, the predicate faults, and visibleWhen fails OPEN — a field gated by a feature flag is shown to everyone. Measured on objectui origin/main (2026-08-25T14:00Z comment on objectui#6262): ZERO authored features.* predicates exist across apps/examples/content, with an 18-hit positive control on authored visibleWhen predicates — a latent trap, not a live break. That is why the ruling narrows the vocabulary instead of building parity machinery for zero consumers (the wiring alternative needs an auth-config fetch on a route that makes none, plus pre-load semantics with a visible-then-hidden flash).

Scope

• Declare and enforce the exclusion where form-view predicates are validated in packages/spec: a form-view predicate naming the features. root is refused loudly at publish/authoring time — a clear error naming the root and the surface — not silently tolerated.
• The rejection is the deliverable; the form-view predicate vocabulary docs state the boundary where authors read it.
• ⛔ Do not widen or change any other predicate surface; app-context surfaces keep features.* as-is.
• Clause-②: yes — this narrows a published accept set; the maintainer ruling above is the authority that floor requires. Contract-review tier at dispatch.
• FIRST action for the dev: re-verify the zero-consumer reading on the day (measurement commands recorded on objectui#6262) and stop-and-report if any authored features.* form-view predicate has appeared since.

Named reader: the domain:spec seat — this lands in packages/spec, the spec lane's sole-owner surface (routing note for triage: domain:spec). objectui#6262 is pm:blocked on this card and closes when the narrowing lands and is re-verified on the objectui surfaces.

Refs: objectui#6262 (the measured asymmetry + ruling record), objectui#6110 / objectui PR #6261 (the current_user half, fixed).

Triage (triage seat, daily round 2026-08-27, session session_01Czs5tCwMymUvzB9QCA2yhH): routed domain:spec, type Task. Rationale: the fix lands in packages/spec (form-view predicate validation surface), the spec lane's sole-owner package; the work implements an already-made maintainer ruling (2026-08-27, Option B on objectui#6262), so it is a ruling-implementation Task rather than a Feature. Dispatch-side note the card already carries: Clause-② yes (published accept-set narrowing) ⇒ contract-review tier at dispatch; first action is the day-of re-verification of the zero-consumer reading. objectui#6262 stays pm:blocked on this card and unlocks on close.

Claim — domain:spec dispatch seat, session session_01JvjTCjJQn9zSTXEhUKgT7s, branch claude/issue-12665-features-root-rejection. Labels swapped pm:queue → pm:dispatched, assignee set in the same stroke. Clause-② card (published accept-set narrowing, ruled 2026-08-27 「同意」 Option B): dispatched at the contract-review tier; needs:contract-review will be hung on the PR per the standing mode:subagent rule and cleared by the review of record. Dev's first action, per the card: day-of re-verification of the zero-consumer reading on objectui origin/main before writing any code, stop-and-report if any authored features.* form-view predicate has appeared.

Claim — os-dev developer for this dispatch, working under the domain:spec dispatch seat (session_01JvjTCjJQn9zSTXEhUKgT7s). Branch: claude/issue-12665-features-root-rejection (pushed; cut from origin/main at f907fbe9). First action per the card: day-of re-verification of the zero-consumer reading on objectui origin/main before any code; will stop-and-report if any authored features.* form-view predicate has appeared.
