The localized catalog spec introduced two package-local translation stubs: one manually looped over interpolation parameters and the other indexed the Chinese dictionary directly. That duplicates framework test plumbing and can drift from the shared lookup, fallback, and placeholder semantics used by the rest of the client suites.
Use makeTranslate from dsh-client-test-runtime as the single Chinese translator for both catalog and read-only composer assertions. Record the test-only workspace dependency in the ui-subagent manifest and lockfile; no production dependency or runtime bundle edge is added.
This removes twelve lines of local translation behavior while preserving the same Chinese assertions and exercising the shared interpolation path. Both ui-subagent test files pass with all 28 tests, the package TypeScript project checks cleanly, and the staged diff passes formatting, lint, and whitespace hooks.
The localized catalog exposed one count.total and one count.running string for every cardinality. The English dictionary therefore rendered both the visible trigger and its accessibility label as 1 subagents, and the assembled Web golden had begun preserving that grammar error.
Split both count families into explicit one and other keys, following the existing client locale convention. SubagentCatalogAction selects the pair from the effective descendant count; English uses subagent for one and subagents otherwise, while Chinese keeps its unchanged classifier text under the same key domain.
Add a component regression proving a single running descendant selects both singular keys. Update the real Web E2E locator and keyless assembled aria golden from 1 subagents to 1 subagent. Both ui-subagent test files pass all 28 tests and the package TypeScript project builds cleanly.
Config() applies the schemastery default at runtime, but its return type
keeps the input's optional field, so assert the resolved shape at the
seam — keeping the dead fallback branch gone.
The catalog action (diagnostics, relative times, loading/error/retry,
mode and activity labels, branch toggles, descendant counts, tree aria)
and the read-only composer were hardcoded to Simplified Chinese, so an
English-locale session rendered mixed-language UI. Register a `subagent`
locale namespace (zh source of truth + en dictionary), declare it on both
slot registrations, thread the locale `t` seat through the components, and
mount the locale service in the plugin specs.
The UI spec's zh assertions now run against the real dictionary through a
`t` stub that interpolates `{name}` params exactly like the locale
service.
The decoration scan read a mutable lexicon() aggregation during render
with no subscription, so a catalog settling or a child spawning after
prewarm left drafted tokens undecorated until an unrelated re-render.
The controller now publishes the aggregation as a snapshot store fed by
a new optional SlashSource.subscribeLexicon hook (ui-skill notifies on
settle/invalidate, ui-subagent forwards the session-list feed), the
composer keyboard face exposes it as an observable, and InputBar
subscribes through uSES. Sources registered after scope birth now warm
and join live controllers via a service broadcast.
eslint --fix autofixes plus manual repairs: max-len line splits
(fake-api handlers, notifier/slots JSDoc, spec signatures), charAt over
non-null-asserted indexing in slash detect/menu cores, Array.from for
code-point capping, typeof assertions for unbound-method in specs,
generic getByRole for the send-button cast, effect disposer void-wrap in
command register, and dropped unused type imports.
