Eliminate sidebar re-render cascades by fixing both sides of the
subscription contract:
- Session-store writes preserve identity: setWorkspaces, mergeWorkspaces,
removeWorkspace, and patchWorkspaceScripts return the previous Map/entry
reference when content is unchanged.
- HostRuntimeController.updateSnapshot only notifies when a patched field
actually changed; idle probe ticks no longer replace the snapshot.
- New canonical hook surface in stores/session-store-hooks.ts
(useWorkspace, useWorkspaceFields, useWorkspaceStructure,
useWorkspaceKeys, useResolveWorkspaceIdByCwd,
useWorkspaceStatusesForBadges, useWorkspaceExecutionAuthority,
useRecommendedProjectPaths, useHasWorkspaces). These are the only
place to subscribe to workspaces.
- 15 greedy subscribers migrated to the hook surface. The sidebar is now
driven by useWorkspaceStructure for identity/ordering; each row
hydrates its own descriptor via useWorkspaceFields, so a workspace
update re-renders only its row. Archive-redirect callbacks switched to
event-time useSessionStore.getState().
- Deleted dead code: use-session-directory.ts, workspace-fetch-debug.ts,
and the unused SidebarProjectEntry aggregates (activeCount,
totalWorkspaces, aggregated statusBucket).
No user-visible behavior change. Targeted tests green (79 tests across
host-runtime, session-store, session-store-hooks, sidebar list, sidebar
row model, sidebar shortcuts, workspace source of truth).
invalidate() flagged the query stale and kicked off a refetch unconditionally,
causing a loading flash every time the model selector opened. Expose
refetchIfStale() instead so callers only refetch when data is actually stale.
* feat: add server-side TTL for provider snapshots and model list UI
Provider snapshots cached forever, causing newly available models
(e.g. OpenCode Go minimax, glm) to never appear in the picker.
Server: ProviderSnapshotManager now returns stale data immediately
and kicks off a background re-warm when the snapshot is older than
5 minutes. Injectable TTL/clock for testing.
App: Provider settings rows show model count and are tappable to
open a diagnostic sheet with a read-only model list (label + ID).
* feat: add per-provider refresh for models and diagnostic
* refactor: await refresh completion and clean up diagnostic sheet state
- ProviderSnapshotManager.refresh is now async; session.ts awaits it so
the RPC ACK reflects real completion instead of just queuing work.
- Preserve models/modes/fetchedAt on entries during targeted refresh so
the list no longer flashes empty mid-refresh.
- Show "Updated Xs ago" next to the Models count, plus loading and
error states for the list body.
- Split resetSnapshotToLoading into full vs targeted branches.
- Flatten nested ternary in model list rendering into renderModelsBody.
- Drop redundant local refreshing state and cargo useMemo wrappers.
* fix(app): widen isImeComposingKeyboardEvent type to accept optional fields
TextInputKeyPressEventData has isComposing and keyCode as optional, so
Pick<KeyboardEvent, ...> was too narrow and broke typecheck on main.
On fresh startup the initial provider snapshot request can return
before providers finish loading, leaving the model picker empty.
The server broadcasts updates once providers are ready, but if the
user opens the picker in the interim they see "No models match".
Invalidate the React Query cache (background refetch, no loading
flash) every time the model selector popup opens so stale data is
silently refreshed.
- Model selector is no longer disabled while providers load; opens
immediately and streams available providers as they arrive
- Selecting a non-default provider on mobile now works correctly
- Provider icon added to model trigger in mobile preferences sheet
- Thinking icon (brain) added to thinking trigger in mobile preferences
- Model descriptions for OpenCode/Pi shown inline next to model name
instead of in a tooltip
- Running agents and draft screen share a single provider/model cache,
eliminating duplicate network requests
- Provider data is prefetched when entering a workspace so the model
selector is instant on first open
