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.
refreshSubagents previously treated every overlapping caller as proof that the in-flight response was stale. Selection, menu opening, and reconnect paths can legitimately request the same catalog concurrently without any host mutation, so those reads were coalesced and then followed by an unnecessary second RPC.
Restore ordinary in-flight coalescing at the public refresh boundary. The debounced host/session-added path now owns the membership-specific stale mark: if its timer fires during an older pull, it queues one trailing request; otherwise it starts the refresh directly. Parent removal keeps its separate explicit invalidation and trailing-refresh path.
Add a regression proving two overlapping reads share one Promise and issue one RPC. Rework the membership test to start from a restored selected parent, so only the host membership frame can request the trailing pull instead of the test priming the stale bit with an unrelated duplicate read.
Validated with both focused catalog cases, all 40 SessionManager tests, and the client runtime TypeScript project build.
The earlier removal fix invalidated parentAvailable immediately and queued a trailing subagent.list request, but it still applied the already in-flight success verbatim. That stale success reopened the composer and became the trailing request baseline. If the trailing request failed, its error snapshot preserved parentAvailable:true indefinitely.
Record a false-only parent availability override on the exact in-flight catalog request when the owner removal frame arrives. Successful and failed responses now replay that request-local invalidation before publishing a snapshot, and addressed child Sessions receive the same effective value. The trailing request therefore starts from a false baseline and a later transport or business failure cannot resurrect the removed parent.
Strengthen the regression to assert the catalog and selected child remain read-only immediately after a stale parentAvailable:true success, then fail the trailing pull and assert the error snapshot remains unavailable. The complete SessionManager test file passes all 39 tests, and the client runtime TypeScript project builds cleanly.
The client plugin now consumes `ctx.locale` (dictionary registration plus
the slot `t` seat), but the package graph did not know it: no
`dshClient.inject` entry, no peer/devDependency, no tsconfig project
reference. Mirror the ui-conversation convention so the dependency graph,
HMR/preflight metadata, and standalone packaging all recognize the
`@deepseek-ai/dsh-client-locale` seam.
The `host/session-removed` invalidation flipped the owned catalog and
addressed children to `parentAvailable:false`, but a `subagent.list` pull
already in flight was requested before the removal and its ok-response
carries the pre-removal `parentAvailable:true` — the response then
overwrote both the catalog and every addressed child, resurrecting the
writable-editor-against-a-dead-continuation-owner bug the invalidation
closes, with no refresh scheduled to converge afterwards.
Mark the owner stale when a pull is in flight at removal time, so one
trailing refresh runs after the in-flight response settles and the
post-removal host truth lands. Adds a regression test: removal mid-pull,
stale ok response, trailing pull, final state stays unavailable on the
catalog and the addressed child.
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.
A removed session can no longer be the delivery owner of its continuable
children, but the `host/session-removed` handler only reconciled the
removed row's own activity. `parentAvailable` was updated exclusively from
`refreshSubagents` success, and removal schedules no catalog refresh — so
after the parent's Activation detaches, an addressed child kept a writable
editor against a dead continuation owner until an unrelated refresh (or
forever, for a closed menu).
Flip `parentAvailable` to false on the owned catalog and push
`handleSubagentParentAvailable(false)` to every addressed child Session at
removal time, matching the refresh path's notification. New Session
instances already read `parentAvailable` from the catalog, so they inherit
the invalidated state.
Adds a regression test: removing the catalog's owning parent flips the
snapshot's `parentAvailable` and notifies the addressed child instance.
`refreshSubagents` single-flights per catalog owner: a request arriving
while a pull is in flight returns the in-flight promise and is silently
coalesced into it. The in-flight response was requested before the
triggering change, so it can never contain that change — a debounced
membership refresh (50ms after `host/session-added`) firing during a slow
pull therefore lost the new child, and the catalog stayed stale until an
unrelated trigger (reselection, menu reopen, reconnect).
Mark the owner stale on coalescing and re-arm one trailing pull in the
settlement `finally`, so every membership change observed during a pull is
carried by a follow-up refresh exactly once. Bounded: the trailing pull
only runs when a refresh request was actually coalesced, and a new
coalescing during the trailing pull re-marks the same set.
Adds a fake-timer regression test: a `host/session-added` debounce firing
mid-pull yields exactly two `subagent.list` calls and the catalog
eventually contains the new child.
The fork button on a stopped assistant message was inert. Frozen
interrupted nodes carry a flow-ordering seq of turnEnd.seq - 0.9, and
session.fork takes a non-negative integer on the wire, so every such
request was rejected as invalid-params before reaching the host — where
an aborted turn's logged turn/end has always made it forkable.
SessionsService.fork floors atSeq at the wire boundary. Flooring stays
inside the anchor's own turn (every turn opens with turn/start), so the
host's first-turn/end-at-or-after cut still closes on that turn.
