Address the three open review threads on the dictionary parity gate.
Regex/TEXT: localeOf now requires an uppercase ASCII [A-Z] flat-letter at
the third position of a name-prefix shape, so zh2Foo/zh_probe are no longer
treated as dictionaries in localeOf while the admission pre-filter skips
them. The two now agree exactly.
register detection now also admits a bare register identifier callee in
addition to a property access, covering a future destructured
register(NS, 'zh'|'en', dict) call instead of silently dropping it.
A 3-arg register whose dictionary argument is a local variable is resolved
through module-scope const initializers; one that cannot be resolved to an
object literal makes the gate refuse with a named error rather than skipping
the registration and narrowing the sweep.
Also restate the FALLBACK_LOCALE rationale: the residual case points at
English because a browser naming neither shipped language is the reader
least likely to read Chinese, not because English is the copy's source
language (Chinese is; packages/client/AGENTS.md). Sync the identical claim
in the bilingual Agent Note and re-record its .i18n.yaml pairing.
The parity gate recognized only a `[['zh',{...}],['en',{...}]]` array, so the
two separate ctx.locale.register(NS, 'zh'|'en', {...}) calls in
ui-permission-presets were unchecked: deleting a key from one side left the
gate green. Pair those calls by their namespace argument. Widen the pre-filter
to admit zhSettings/accessZh spellings, which a bare \b(zh|en)\b misses and
would have skipped before parsing.
Assert document.documentElement.lang in the assembled app. The served markup
already ships lang="en", so the fr-FR scenario passes whether or not the sync
runs; the zh scenario is the discriminating half and now asserts zh-CN before
the switch and en after it.
Drop the dead vi.unstubAllGlobals() from the document-language spec, which
manages navigator with defineProperty and never calls vi.stubGlobal.
Restore @deepseek-ai/dsh-client-test-runtime in ui-settings-general: the
package still imports bindSnapshotSelector from it in
tests/components.client.spec.tsx, so removing it was manifest drift. The
earlier knip report predated that file arriving on this branch.
Swallow only ENOENT when reading a directory in the parity gate. A broad catch
treated EACCES or an I/O failure as "absent", which would narrow the sweep and
let the gate pass while checking less.
