The native adapter's route was named deepseek, colliding with pi-ai's
catalog provider of the same name, so the two DeepSeek paths could never
be mounted side by side. The web settings page needs both configurable at
once. Compositions, fixtures, goldens, scaffolding defaults, and docs all
move together (pre-release, no shim); TUI/session-query-spill/
missing-credential goldens re-recorded through their keyless refresh
modes because provider-name length shifts box padding and spill
truncation points.
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.
Master's #660 replaced dsh-subagent-subprocess with the dsh-subprocess
capability seam (ctx.subprocess + scrubbedParentEnv, tree-scoped teardown)
and moved subagent-acp onto it. Convergence for this branch's packages:
- The shared out-of-process provider vocabulary this branch had grown in
the deleted library (NO_START_CAPABILITIES, assertPositiveFinite, cwd
resolution, settleRunResult, subprocessRunHandle) moves into the subagent
seam package as out-of-process.ts — it enforces subagent-seam contracts,
not process mechanics, and both out-of-process backends now import it
from there (subagent-acp keeps master's shape otherwise).
- subagent-sdk spawns THROUGH the SDK client (the subprocess README's
documented exception for SDK-managed transports) and now applies the
seam's scrubbedParentEnv() + explicit-env merge in place of the deleted
buildChildEnv.
- sdk-client inlines the EOF→SIGTERM→SIGKILL ladder as private helpers (it
runs outside any harness context, so it cannot ride ctx.subprocess).
- The child harness fixture gains the now-required dsh-subprocess-local
entry for bash-local; the fixture cordis.yml keeps exercising the
shipped provider default.
- 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.
The aborted-mid-stream case raced the abort against the child's chunk
delivery across two pipes and lost under full-suite load. Replace it with a
same-pipe ordering probe: the fake streams one text-delta chunk and then
answers the prompt with a malformed (non-accepted) result, so frame order
guarantees the chunk precedes the failure — the accumulated partial text
must survive into the error result. Same code path (collectOutput without a
complete assistant/message), no timing window.
- 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.
- @deepseek-ai/dsh-sdk-protocol: extract the line transport from dsh-jsonrpc
and name the request/result/notification wire types both ends share; error
responses preserve wire code/data via JsonRpcResponseError.
- @deepseek-ai/dsh-sdk-client: TypeScript twin of the Python SDK — spawns the
dsh-jsonrpc-agent runtime as a subprocess, drives stdio JSON-RPC turns
(DeepSeekHarness high-level API + HarnessClient protocol client), scopes
notifications to session trees client-side, and reaps the child through the
shared subprocess dispose ladder.
- @deepseek-ai/dsh-subagent-sdk: out-of-process subagent backend driving a
child harness runtime through the TS SDK; shares cwd resolution with
subagent-acp via new dsh-subagent-subprocess cwd helpers.
- Keyless unit suites drive real subprocesses (scripted fake runtime peer);
100% per-file coverage on all touched packages.
