deepseek-harness/packages/client/runtime

@deepseek-ai/dsh-client-runtime

Client cordis boot + core services: SlotsService (Service wrapper over SlotCore + 'slots/changed' bridge), SessionsService (list store projection, scope tree, bindings, ancestry), the Session object layer (exported as a type; instances are owned and handed out by SessionsService — the manager/paging internals stay package-internal, tests reach them via src), ClientLoader (./loader subpath, statically held by the shell). Contract: api-contracts v3 §4.

Model Experience

None, as the client runtime hosts browser-side services and the session object layer; nothing here reaches a model request.

KV Cache effect

None; this package neither assembles nor sends a provider request.

Known Limitations and Deferred Work

• loader.unload is a stub (throws not-implemented) — the full chain (fiber dispose → registration cascade → style removal) lands with the HMR project.
• Scope teardown is watch-approximated — the most recently resolved binding stands in for "who is watching"; a removed-while-watched session's scope survives until the watch moves away, not until true observer count reaches zero.
• Value imports of this package from plugin bundles must use the /client subpath — the bare package name is not in the loader externals table and inlines a second module instance, whose private scope-tag Symbol never matches (the empty-state P0 postmortem).
• SessionSummary.title is a display projection — the wire summary carries no title yet; the cwd basename stands in, then the raw id.
