A Traditional Chinese console reads and writes the Simplified entry of an inline label map

Filing gate: ① product defect, named location. Out-of-scope finding S1 of the contract review of PR #30902 (6682790803, card #30511), which makes zh-Hant a console language. ⛔ Not a claim. Triage sets the grade and the lane.
class: a · reach: every inline locale map an author writes with both a Simplified and a Traditional key, read or edited in a zh-Hant console session; NOT MEASURED live (read in code on origin/main 98f640d581 and on the PR branch, where pickLocalized.ts is unchanged).

Business reason

After #30902 a Traditional Chinese user (Taiwan, Hong Kong) gets Traditional chrome, but an object or field label written as { en, 'zh-CN': '客户', 'zh-TW': '客戶' } still shows the Simplified zh-CN entry to them, and an edit they make in Studio lands on the zh-CN key, overwriting the Simplified authors' text while the zh-TW entry stays stale. The tenant sees mixed scripts on one screen and loses text on save.

Where

ui/packages/i18n/src/pickLocalized.ts pickLocalized: for language = 'zh-Hant', read('zh-Hant') and read('zh') miss, then the region limb takes the FIRST own key sharing the base zh (zh-CN in authoring order), never a key of the same script.
Same file, localeWriteKey (the write-side twin): the same first-sibling limb picks the key an edit is written to.

Wanted

Measure first on the feat(i18n)!: the Console's language packs follow the platform locale table, keyed by its tags, and Traditional Chinese (zh-Hant) ships #30902 head (or main after it lands): a zh-Hant session over a map holding zh-CN and zh-TW (and zh-Hant / zh-Hans spellings); record which entry is read and which key an edit writes.
If it reproduces: the read and write limbs prefer a key of the same script (the spec's PLATFORM_LOCALE_READ_ALIASES / platformLocaleTagOf already say zh-TW / zh-HK mean zh-Hant and zh-CN / zh-SG mean zh-Hans), and only then any zh-* sibling. One reading for both limbs, never two copies.
Pin both limbs with a test per spelling plus an ablation.

Level: client behaviour only, expected Clause-②: no, Metadata-protocol: none.

Reader: domain:ui (ui/packages/i18n/src/pickLocalized.ts).
Serial: after PR #30902 (#30511), which adds the zh-Hant language.

⛔ Not a claim.

A Traditional Chinese console reads and writes the Simplified entry of an inline label map. That is a client behaviour defect from the i18n phase 2 (Console UI): ui/packages/i18n reads PLATFORM_LOCALES, adds zh-Hant, and moves pack keys to table tags #30511 contract review (S1), where zh-Hant becomes a console language. p2, the i18n phase 2 (Console UI): ui/packages/i18n reads PLATFORM_LOCALES, adds zh-Hant, and moves pack keys to table tags #30511 family grade. finding is removed.

Clause-②: no
Metadata-protocol: none
Responsibility: ui/packages/i18n (objectstack) pickLocalized / localeWriteKey take the first zh-* sibling key regardless of script · the platform path is the spec's locale table (PLATFORM_LOCALE_READ_ALIASES / platformLocaleTagOf), which says which tags mean zh-Hant · reached by any Traditional Chinese session reading or editing an inline label map; NOT MEASURED, the dev measures first
Thread-read: 6683176666
Premise: holds (pickLocalized.ts on origin/main 7d9682ff: the region limb is Object.keys(o).find((k) => k.split('-')[0] === base …), script-blind) · measured first by the dev
Serial constraints cleared: PR #30902 (#30511, this seat) touches ui/packages/i18n/** but not pickLocalized.ts; this claim edits no file in #30902's list.

Claim amendment 1 · 2026-11-06T12:05Z · to claim 6684338116
File surface (widened): ui/packages/i18n/src/pickLocalized.ts and its tests; packages/spec/src/ui/i18n-label-resolver.ts and its tests (the spec twin resolveI18nLabel, which has the same script-blind first-sibling limb, measured by the dev); the plugin-list i18nLabel-resolver-parity test (both-script rows); root .changeset/ (@object-ui/i18n + @objectstack/spec patch). ui/packages/i18n/package.json and pnpm-lock.yaml ⛔ (PR #30902 adds the @objectstack/spec dependency; this branch merges main after #30902 lands and does not touch them).
Why: fixing the client twin alone would split one console session (nav and app-shell Simplified, plugin text Traditional); the parity test pins both to one rule.
Review owed: the diff will touch a published spec source (packages/spec/src/**), so a CONTRACT_REVIEW_TIER contract review is owed on its head before ACCEPT.
Serial: lands after PR #30902.

Claim amendment (#30910) · 2026-11-07T01:18Z · the file surface widens to fix contract review FAIL 6700222070 on PR #31068:

M1: ui/packages/app-shell/src/views/metadata-admin/previews/navItemLabel.ts (ownEntryKey → the shared limb) and its tests.
S1: packages/cli/src/utils/i18n-coverage.ts (inlineLocaleText) and packages/cli/test/i18n-inline-locale-map-coverage.test.ts (a two-script fixture).

Everything else in the claim and in amendment 6684414838 stands. A delta review by the same reviewer follows on the new head.
