The client's todos projection derived only from the paged display window, so reopening a session whose last todo/write preceded the tail page showed an empty plan until the user paged back — session-level state cannot be reconstructed from an arbitrary window. The host owns the full log, so the tail history response now attaches todos (latest todo/write backscan, the same posture as the view pairing); installWindow seeds it, window rebuilds preserve it, and any in-window or live write keeps overwriting it. The fixture mirrors the host; docs and both Agent Notes record the mechanism.

# @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. `ConversationSnapshot` carries `todos` — the session-level todo projection: seeded from the tail history page's full-log projection (`history` response `todos`), overwritten by every in-window or live `todo/write` (last write wins), and preserved across window rebuilds.

## 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).
|
|
- **`SessionSummary.title` is a display projection** — the wire summary carries no title yet; the cwd basename stands in, then the raw id.
