The client indexes tool/code-dispatch events into ConversationSnapshot.codeDispatches (parent callId -> ToolResultNode-shaped sub-calls; live mux and history replay build the identical index). ChatView renders each run_code parent as the new code variant (description summary, program as the expanded monospace body) with its sub-dispatches as always-visible indented rows — every sub-row dispatches through the SAME keyed conversation.chat.toolview hole with the same GenericToolCard fallback, so custom registrations (bash sample) take over sub-rows exactly as top-level rows. The details panel resolves sub-callIds to full logged args and complete output through the native path. Evidence: fixture turn 64 + built-bundle jsdom snapshot, real-machinery jsdom suites (nesting, error state, details, running parent, reference stability), and a recorded code-mode browser e2e round (keyless replay + aria golden). Scaffold gains a toolsMode patch knob.
@deepseek-ai/dsh-client-connection
Wire consumer layer: the client plugin's apply mounts ctx.connection (shared api client + single-consumer stream-loop starter); the export face carries the wire contract types, the AbstractApiClient seam, and the loop's sink/config types. The platform subclasses (WebApiClient/FixtureApiClient), the ConnectionController loop, and the fixture data source are package-internal — apply selects and drives them; tests reach them via src. Contract: api-contracts v3 §3.
Keyless fixture
Any fixture query parameter selects the in-memory carrier. fixture=empty starts with no Workspace or Session; fixturePrompt=reject rejects prompts before acceptance; fixtureAttach=fail publishes a Session but rejects its Workspace attachment; fixtureSessionCreate=drop-response publishes and frames a Session before dropping the create response; and fixtureFrames=workspace-first reverses the default session-first create-frame order. Workspace creation by name/path and caller-preallocated SessionIds remain deterministic enough for assembled Web tests to reconcile list and frame arrival.
Model Experience
None, as the wire consumer layer moves already-composed messages between browser and host; nothing here reaches a model request.
KV Cache effect
None; this package neither assembles nor sends a provider request.
Known Limitations and Deferred Work
- history's implicit resume is arguable — opening history on an unattached session pulls an agent up host-side; the pure-persistence-read alternative is recorded in the rt-core reconciliation ledger, unchanged in P-I. This package's consumers see it as latency on first open.
ToolEventView/ToolCallView/ToolResultViewre-exports are scheduled for removal — they fall when the toolview migration deletes the hostviewForline (presentation belongs to the client); the fixture keeps a localviewFormirror until then.
