CI captured `- text: Loading history…` where the golden holds the grandchild's
first message. The only wait before that capture is the offline banner, which
renders from the descriptor and says nothing about the transcript below it,
and `captureStableAria` calls two identical polls stable — two of which can
both be the loading placeholder on a loaded machine.
Waiting for the message the golden asserts makes the precondition match the
assertion. The race is not observable here (the history is already loaded when
the banner appears, so the wait returns in ~1ms), so this is reasoned from the
CI log and the helper's semantics rather than from a local reproduction; if
the history instead never arrives on CI, the lane now times out on the missing
message rather than committing a loading placeholder to the diff.
The subagent conversation scenario asserts English role names and compares English accessibility goldens, but it opened a raw Playwright page while the rest of the English Web scenarios use the shared bootstrap that writes dsh.locale before client initialization. Once the subagent surface became localized, the raw page left those assertions dependent on ambient browser or persisted locale selection.
Create the page through newEnglishPage so the product sees an explicit English preference before boot, while preserving the standard 1680 by 1000 viewport. Chinese-surface scenarios continue to bypass this helper and advertise their own locale explicitly.
A fresh library build and production Vite build completed successfully. The focused assembled subagent-conversation Web suite then passed all 8 keyless replay tests against the updated singular-copy golden, 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.
The ui-subagent catalog and read-only composer copy moved from hardcoded
Chinese to the locale-aware `subagent` namespace, so an en-US headless
browser now renders English. The e2e's selectors and goldens still
asserted the old hardcoded Chinese strings, leaving the scenario unable
to find the catalog trigger.
Convert the selectors to the default (en-US) render and re-record the
catalog goldens (ui, tree, nested) in English. The locale-aware parts of
the remaining goldens were already English (recorded under the en-US
default), so sidebar and fork are untouched.
