07akioni aeb8b1f486 feat: implement new session behavior to clear selection and show empty state
- Added bilingual notes for the new session feature, detailing the transition to an empty state upon session creation.
- Updated `SessionsService` to include a `clear()` method that resets the current selection and persists the empty state.
- Enhanced the `EmptyState` component to reflect the new design, including workspace selection and input handling.
- Modified CSS styles for improved layout and visual consistency in the empty state.
- Updated tests to cover the new session clearing functionality and its effects on the UI.

@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.

Session title projection

SessionManager retains the latest validated session/title control snapshot independently of list and session-instance arrival. Newer event seqs replace older snapshots, title timestamps contribute to list recency, and a subscription baseline discards any retained title beyond its lastSeq before the optional folded title arrives. Explicit session removal also clears the retained title. The client-facing SessionSummary.title is therefore only the actual durable title; displayTitle is always present and falls back through the cwd basename and session id. A cold persisted session keeps that fallback until opening or resuming it causes the host to fold and project its log-backed title.

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 stage-driven, single-occupant today — the staged session follows list.current exactly (staging is the open signal: the event window opens ⟺ the session is on stage); a removed-while-staged session's scope survives frozen until the stage moves on, not until true observer count reaches zero. Resolution (cell()/binding()/scope()) is pure addressing, render-safe. The staged state can widen to a multi-pane list when concurrent panes land.
  • 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).
