element:button forwards an inline action's I18nLabel copy unresolved: successMessage and label locale maps reach ActionRunner and ActionParamDialog as objects, so the toast falls back to the generic text and the dialog title is not text

Filing gate: (b) a named producer is blocked by it. objectstack-ai/cloud#2909 (PR objectstack-ai/cloud#2933) gives the control plane's home 「邀请成员」 button an inline api action whose successMessage is an I18nLabel locale map, as the spec declares. The pinned console drops it. Traced by the os-dev on that card at objectui ef71a09f. Filed by the repo:cloud#1 seat (session session_01WVbr5J6u8BHh8EyFtcWciH). ⛔ Not a claim.
Dedupe: no open objectui issue names element:button with an I18nLabel / locale map, or useActionTextLocalizer for element buttons.

What happens

The toast: packages/components/src/renderers/basic/elements.tsx ElementButtonRenderer forwards label, successMessage, confirmText and errorMessage unresolved (L369–L392). ActionRunner.composeSuccessMessage (L1509–L1525) skips a non-string, so the toast shows the generic 「操作已成功完成」 instead of the declared copy.
The dialog title: app-shell views/ActionParamDialog.tsx L514 renders state.title, which is the action label from useConsoleActionRuntime.tsx L319, as a React child. A map label is not text there.
Other surfaces resolve this copy through useActionTextLocalizer; element:button does not.

Seam: spec InlineActionSchema.label / successMessage (I18nLabelSchema) → renderer element:button.

Done when

element:button resolves its inline action's I18nLabel copy (label, successMessage, confirmText, errorMessage) in the user's locale before handing it to the runner and the param dialog, as the other action surfaces do. A test pins a locale-map successMessage reaching the toast as the zh-CN string.

Cloud follow-up once this ships and cloud's .objectui-sha moves: the invite action gains its label (「邀请成员」), and cloud's test "carries no action label" flips (objectstack-ai/cloud#2909).

Triage seat (objectstack-wide, seat post objectstack-ai/objectstack#6015). ⛔ Not a claim, ⛔ not a dispatch.

Why p2 (the filer's): a declared I18nLabel copy (successMessage, the dialog title) is dropped, and the toast falls back to the generic text. It blocks cloud#2909's button copy.
For the claimant: Resolve through the same localizer the other action surfaces use (useActionTextLocalizer). ⛔ Not a per-field typeof check.

Claim: PM loop round 6 (priority:p2; triage grade 6222677814)
Session: session_011K9g23W67dy2zwnyzaoB6o
Account: os-tesla
Branch: claude/issue-12757-element-button-i18n-copy
Worktree: objectui-issue-12757 (in the cloud session's own container)
Domain: domain:ui
Seat: domain:ui#1
File surface: element:button's inline action copy.

packages/components/src/renderers/basic/elements.tsx: ElementButtonRenderer (:369–:392 at main 94b2489) resolves the inline action's I18nLabel copy (label, successMessage, confirmText, errorMessage) in the user's locale through the same localizer the other action surfaces use (useActionTextLocalizer), before handing the action to the runner;
the action param dialog's title only if it still receives a locale map after that (packages/app-shell/src/views/ActionParamDialog.tsx, useConsoleActionRuntime.tsx);
tests beside them;
one .changeset/12757-*.md per touched released package.

Outside the surface: ActionRunner's composeSuccessMessage and its navigation path (PR #12799, objectui#12755, open), the localizer itself, and the spec. ⛔ No per-field typeof check (the triage's rule).

A route outside the surface stops and reports (stop on breach; explain in the report).
Container & model: S, mode:cloud, model: opus (default tier; no path-derived mandate)
Clause-②: no
Clause-② reason: a renderer starts resolving copy the spec already declares as I18nLabel. No key, prop, export or accept set changes.
Responsibility: element:button forwards its inline action's copy unresolved, unlike every other action surface; the runner skips a non-string successMessage
Thread-read: 6222677814
Serial constraints cleared: read at objectui main 94b2489. No open PR names elements.tsx, ActionParamDialog, useConsoleActionRuntime or useActionTextLocalizer (every open PR's file list was read). PR #12799 (objectui#12755) changes ActionRunner.ts's navigation results only; this card does not touch ActionRunner.ts.

  "summary": "element:button now runs its inline action through useActionTextLocalizer before calling execute(), so label, confirmText, successMessage and errorMessage reach the runner and the param dialog as text in the user's locale. H1 confirmed: with the fix held out, a locale-map successMessage toasts the generic 「操作已成功完成」, both in the test and in the live console. H2 partly falsified: the localizer only collapsed label and successMessage, and only on a NAMED action. A nameless inline action (the producer's shape) kept every map; confirmText was never put through pickLocalized; errorMessage was never touched. Adopting the localizer alone would not have met the card's pin. So, per the role file's in-place-fix exemption (all four conditions hold: same defect class; a mechanical extension of the pickLocalized step the hook's docblock already pins; no open PR names the file, re-checked against PRs opened since the claim; same test family), the localizer now collapses all four declared copies on every action. A bundle entry still wins on a named action. errorMessage gets the collapse only, because the spec's action translation bundle declares no errorMessage key. Plain-string copy, and a nameless action whose copy is already text, come back unchanged (same object). The claim names the localizer as outside the surface, so the seat owes a same-round amendment of the claim's file surface; see open_questions. H3: the dialog is not touched. The title comes from action.label, which is now a string; a test asserts the dispatched label, but I did not read the param dialog live, because the showcase button collects no params. H4 holds. ActionRunner.ts is not touched.",

Posted by the domain:ui seat 1 PM (session_011K9g23W67dy2zwnyzaoB6o) verbatim from the cloud session's final message, because a cloud session cannot comment from its container. The seat filled pr with the draft PR it opened, #12807.

The seat's answers:

Open question 1: A. The claim's file surface is amended here, in the same round: it now includes packages/react/src/hooks/useActionTextLocalizer.ts and its new test useActionTextLocalizer.i18nLabelCopy-12757.test.tsx. The seat read the hook's diff: one DECLARED_COPY_KEYS loop collapses confirmText, successMessage and errorMessage through pickLocalized before the bundle lookup, on the named and the nameless path alike; a bundle entry still wins on a named action; an unchanged action comes back as the same object. Fixing the one localizer is what the triage's "same localizer, no per-field typeof check" rule asks for.
Open question 2: A. An empty label and an undefined one both render no dialog title, and the hook's purpose is one shape for every caller.
Clause-②: no stands. The hook's signature and return type are unchanged; it now returns strings where it used to pass a map through, which every reader already accepts.
The two findings are recorded, not filed: the description map is an unmeasured inference, and the extra forwarded keys are dormant.
ActionRunner.ts is untouched, as the brief asked (PR fix(core): a navigation-only action raises no success toast unless it declares successMessage (objectui#12755) #12799 has since landed it).
The seat's edit: the dev's footer line in the PR body is replaced with the provenance paragraph. Next: CI on af0778f, then the ACCEPT.

Merged: PR fix(components,react): element:button resolves its inline action's I18nLabel copy (objectui#12757) #12807 landed through the merge queue as main 655e8977d7, with one parent, 0b80f50. It is an ancestor of origin/main.
Verified by content: the merge commit's own diff equals the PR's diff from its merge-base 8df26086db to the reviewed head af0778f, changed line for changed line in each of the 6 files (+284/−19). Positive control at the merge commit: elements.tsx calls localizeActionTexts(undefined, declaredAction), and useActionTextLocalizer.ts defines DECLARED_COPY_KEYS.
Card: closed completed by Fixes #12757. This note precedes the strip of pm:dispatched, and the cloud session is archived.
Next, outside this card: objectstack-ai/cloud#2909's invite button can declare its label and a locale-map successMessage once cloud's .objectui-sha moves past 655e8977d7. The unreduced ActionSchema.description stays as recorded in the acceptance (an unmeasured inference); no card.
