Dismissed completed task lists are a user visibility choice for that completed cycle, so polling the same persisted tasks during the next chat turn should not resurrect the bar. The store now keeps the dismissed completion key while the remote reset is in flight, and the markdown renderer gives default lists enough inset so bullets stay inside message cards.
Constraint: Preserve future task cycles when new TodoWrite or task updates arrive.
Rejected: Clear only the visible task array | polling can rehydrate the same completed list before remote reset finishes

Not-tested: Live Tauri chat session task creation and dismissal
Desktop chat sessions can stream and reconnect concurrently, so shared in-process buffers must not be keyed only by process lifetime. This change scopes streaming delta buffers, task-tool refresh bookkeeping, and CLI task mutations to the session that produced the event. It also ignores stale client socket closes after a newer socket has replaced the active connection for the same session.
Constraint: Desktop users can keep multiple sessions and tabs active at the same time.
Rejected: Serialize all desktop streaming through one active session | would hide the race instead of preserving multi-session behavior.
Confidence: high
Scope-risk: moderate
Directive: Do not reintroduce process-global chat/task pending state without session keys and multi-session regression tests.

Completed desktop task bars were only being dismissed locally, which let the
persisted task list resurface on refresh or bleed into the next user turn.
This wires the existing server-side reset path into the desktop stores and
session flow so a finished task cycle is summarized once, cleared locally,
and removed remotely before the next round starts.
Constraint: Existing task persistence already lives behind the server task-list API and must stay compatible with persisted JSON task files
Rejected: Only hide the completed task bar in UI state | left stale persisted tasks behind and reintroduced them on reload
Rejected: Clear desktop state without a task summary | dropped useful completion context from the chat transcript
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep desktop task dismissal and task-list persistence behavior aligned; do not reintroduce local-only clearing without covering reload and next-turn flows

Tested: `bun test src/server/__tests__/e2e/business-flow.test.ts --test-name-pattern "Task Lists API"`
Not-tested: Full `bun test src/server/__tests__/e2e/business-flow.test.ts` suite still has unrelated pre-existing failures in Models and Sessions sections
The desktop task bar used a single global task store, but session switches
could leave it pointed at the previous conversation. Re-entering an already
connected session skipped task refresh entirely, and changing task list IDs did
not clear stale tasks before the next fetch resolved.
This change refreshes CLI tasks on every session activation, clears stale task
state immediately when the tracked session changes, and locks that behavior
with regression tests around reconnect and cross-session task isolation.
Constraint: The current desktop task bar architecture uses one shared CLI task store across sessions
Rejected: Per-session task store refactor | too broad for a targeted bug fix
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: If tasks become session-scoped later, re-evaluate the eager refresh in connectToSession before removing it
