Node >= 21 exposes a global `navigator` reporting the machine's own language,
so gating detection on `navigator` let a non-browser boot of the client tree
resolve to `en` instead of the documented fallback; `window` is the browser
test. `navigator.languages` is spec-required but absent on some embedders and
older WebViews, where spreading it would throw at boot, so the walk tolerates
its absence and `navigator.language` covers that host.
The per-spec pin boilerplate collapses into one suite-level
`usePinnedBrowserLanguages('zh-CN')`, which owns the rationale in
dsh-client-test-runtime, and the English-browser e2e scenario now clears the
console warnings channel too — its page has no closing inventory spec.
A first visit resolved to Chinese regardless of the browser: LocaleService
read `dsh.locale` and fell straight back to `zh` when nothing was stored,
ignoring the languages the browser already states it reads.
The initial locale now resolves through three ordered sources — the persisted
preference, then `navigator` (first entry of the ordered language list whose
primary subtag names a shipped locale, so `zh-Hans-CN` -> zh and `en-GB` ->
en), then `FALLBACK_LOCALE`. An explicit choice still wins and nothing writes
the detected locale back to storage, so "has the user chosen?" stays a
question only the stored value answers.
Specs asserting the shipped Chinese copy now state the browser they assume:
the web e2e scenarios open their page with `locale: ZH_BROWSER_LOCALE`, and
package specs pin it through the new `pinBrowserLanguages` test helper.
`settings-chrome.e2e.ts` gains an English-browser scenario as the
assembled-app proof.
Sink the behavior previously held only by the apps/web jsdom snapshots
into the owning packages, each bench mounting the real apply on the
production slot machinery with fixture-fed data:
- ui-conversation/assembly-surfaces: the todo_write turn reaches both
product surfaces (keyed toolview row + dock plan strip via the todos
projection) and the strip follows projection retirement; the keyed
bash row carries its resident terminal card while the fallback row
reaches one through expand; the locked no-session view state; the
composer textarea surviving the blank→active conversion as the same
DOM node; the promptError alert strip with the machine-restored
draft; one summary update re-labeling the breadcrumb.
- ui-workspace/rename-assembly: the session-rename chain (row menu →
dialog → the injected renameSession hop → ISession.rename with the
edge-trimmed draft → dialog close and row re-label from the list),
plus the rejected arm keeping the dialog open with the error.
- runtime/workspaces-service: startInitialSelection — connects the
recent Workspace once both baselines are ready and opens the session,
stays idle with a current session or no recent target (double start
fails loud), and a failed connect returns to waiting and retries on
the next list change.
Component-level arms stay in the existing package suites; these files
prove only the assembled wiring.
