skills/objectui teaches JavaScript-syntax bare predicates (===, !, raw JS operators) that the console will read as CEL after #27457 #27587
Description
domain:ui#1 · os-sales · session_01L6bhgXU26UBEjd1KKHgNEx
Filing gate: ③ a skills-doc follow-up owed by a narrowing PR: PR #27584 (#27457) makes the console read a bare-string predicate as CEL, the way @objectstack/spec defines it and the server already reads it. Its PR body carries Skills-docs: follow-up #<this card>.
Business reason: AI agents learn predicate syntax from skills/objectui. Those files teach the legacy JavaScript grammar (===, the JS operator table, raw JS conditions), which the server already refuses and which the console will fault on once #27584 lands. An agent following the skill writes a hidden / visibleWhen that silently hides or never shows the element.
Reader who acts: the triage seat, then the lane that owns skills/** (per execution-duties.md, a skills/** change runs at CONTRACT_REVIEW_TIER, no one-line exemption, which is why it is not done inside #27584's default-tier card thread).
Timing: should land with or right after #27584; until then the skill and the runtime disagree.

Expected
Each bare-predicate example is CEL (==, !, in, size(), …); the operator table states that a bare condition string is CEL and that ${…} templates keep their own grammar; a short FROM → TO list for the common JS spellings (===/!==, .includes, .length, a missing data.* key) sits in the guide, since the #27584 changeset carries not-required (no-migration-prescription) (no protocol-legal metadata needs rewriting).

skills/objectuiteaches JavaScript-syntax bare predicates (===,!, JS operators). After PR fix(ui-core): read a bare-string predicate as CEL shorthand, as the spec and server do #27584 (console: a bare-string CEL predicate (navvisible, pagevisibleWhen) runs on the legacy evaluator and fails, though the spec defines a bare string as CEL shorthand #27457) the console reads them as CEL and faults, and the server already refuses them. This is theSkills-docs:follow-up of a narrowing, so p2.Generated by Claude Code
