The group's convention is package suffix == provider default
(subagent-acp/'acp', subagent-spawn/'spawn', subagent-fork/'fork'), and the
provider default became dsh-sdk in the last review round — so the package
follows: @deepseek-ai/dsh-subagent-dsh-sdk at
packages/subagent/subagent-dsh-sdk, plugin name subagent-dsh-sdk,
diagnostics prefixed subagent-dsh-sdk:. The dsh echo has precedent
(dsh-llm-deepseek). Directory, fixture path, knip/tsconfig/examples
registrations, catalogs, READMEs (en+zh), and the Agent Note follow; the
sdk-client dispose ladder moves to its own module (src/dispose.ts) with the
deterministic FakeChild tier tests restored alongside it.
- api: resolve a relative workspace cwd to absolute before the handshake —
the child spawns relative to the parent cwd, but the wire cwd is resolved
again inside the child, so a relative value double-resolved
(worker -> worker/worker).
- api: make the documented handshake retry real — HarnessClient.close() is
permanent, so a failed initialize now reaps the runtime and swaps in a
fresh client; DeepSeekHarness.close() is terminal and stops the respawns.
- api: validate session.event envelopes, assistant/message content, and
session.finished reasons at the wire boundary — a malformed runtime
surfaces as SdkProtocolError instead of type-invalid TurnResult data or a
TypeError out of finalResponse.
- client: a throwing subscribe() filter fails and detaches only its own
subscription (normalized to Error); sibling fan-out and the transport read
loop are undisturbed.
- client: NotificationSubscription.close() drops its queued notifications,
matching its documented contract; runtime-death fail() still leaves
already-delivered items drainable.
- client: subscribe() after close()/runtime death returns a born-failed
subscription so next() rejects instead of parking forever.
- client/transport: bounded requests abandon via AbortSignal — the transport
drops the pending entry at timeout, so repeated bounded calls against a
hung method retain no per-call state.
One test per finding; per-file coverage stays 100% on both packages.
- examples/jsonrpc-agent gains its first snapshot suite (sdk.snapshot.ts):
the real dsh-jsonrpc-agent runtime driven through the real dsh-sdk-client,
keyless llm-replay behind a new cordis.snapshot.yml overlay; three recorded
scenarios (text turn, bash tool, spawn subagent) pin the notification
stream, the SDK turn result, and the persisted parent+child session logs.
- Bilingual READMEs for dsh-sdk-protocol / dsh-sdk-client / dsh-subagent-sdk;
sdk/ and subagent/ group tables extended; dsh-jsonrpc README points at the
extracted protocol package; Agent Note (en+zh) owns the decision.
- The proposed make-jsonrpc-directional note is updated for the transport's
new home and its second (client) consumer.
- Model Experience sentence allowlist entries for the two client-side
packages; module graph + config catalog regenerated; i18n pairings
recorded. doc-sync passes 24/24.
