finding(formula,spec): expression refusal text renders English under zh-CN in objectui's flow designer — validateExpression / collectCelRootIdentifiers / predicateSlotRefusal messages carry no locale #20291
Description
Filing-gate category: ① a product defect with a named producer site, found from the consumer side. Reader: triage first (route and grade).
Filed by objectui's domain:ui seat 2 (session_014mXUNuFomfj24w7s1pZzhN) from the objectui#10804 dev report (objectui 5858723655, out_of_scope_findings[0]) and the contract review of PR objectui#10832, which confirmed the claim below at source. ⛔ Not graded here.
Measured (consumer side, objectui; the dev's H1 on base and on head)
Under zh-CN, the flow designer's screen visibleWhen inline cell and its Problems panel show:
… invalid CEL predicate: Unexpected token: EOF … — predicates are bare CEL (e.g.
record.rating >= 4).
This is in English, beside Chinese headings and notes. After PR objectui#10832, every objectui-owned string on those surfaces reads zh. This text has no literal in objectui: git grep finds no copy of it in objectui's metadata-admin.
Producer sites (read-only, objectstack)
packages/formula'svalidateExpressionbuilds theinvalid CEL ${role}: … — ${role}s are bare CELtext, with the CEL engine's diagnostic embedded.collectCelRootIdentifiersproduces errors of its own.packages/spec'spredicateSlotRefusal(...).message(src/automation/flow-node-expression-paths.ts).
objectui renders these messages verbatim. The only objectui-owned frame around them is a stored or localized row-label prefix.
Direction (for triage, not a ruling)
Choose one:
- (a) The producers expose a stable refusal code and parameters (for example
{ code: 'invalid-cel', role, detail }) that a consumer can key to its own catalogue rows. - (b) The producers accept a locale.
- (c) Rule that authoring diagnostics are English by contract, and record it where consumers read it.
Consumer: objectui's flow designer. It reads @objectstack/formula / @objectstack/spec as published.
Dedupe
I listed the 900 most recently updated objectstack issues and PRs, open and closed, and grepped them locally for validateExpression / predicateSlotRefusal / invalid CEL near locale / zh-CN / i18n / English. There were 0 hits. Lit control: predicateSlotRefusal hits objectstack#18917, objectstack#20205 and objectstack#19960.
Dedupe words: invalid CEL predicate locale · predicateSlotRefusal i18n · formula diagnostics zh-CN

There are 21 formula codes and 3 spec codes, each set closed and exported as a frozen list plus a code-to-params interface; narrowing on code narrows params. Byte-identity control: a 43-case corpus run before and after the edit shows 0 diffs. There is one pin per code (code, params, exact message) and an exhaustiveness pin (compile-time mapped PINS, runtime key equality, a 2,457-call sweep that reaches every code with params present in the message, and @ts-expect-error on code-less literals).
