+//! Materialises an autonomous task-board run as a top-level "task session"
+//! conversation thread, so background agent work shows up in the
+//! Conversations → Tasks tab exactly like a manually-launched todo.
+//!
+//! A manually-run todo (`handleWorkPersonal` in the app) creates a top-level
+//! thread labelled `tasks` and streams the agent turn into it. Autonomous card
+//! runs (`task_dispatcher`) previously ran headless with no thread, so they
+//! never appeared in chat. This module gives them the same surface:
+//!
+//!   1. [`create_session_thread`] — a **top-level** (`parent_thread_id: None`)
+//!      thread stamped `labels: ["tasks"]`, seeded with the task prompt as the
+//!      opening `user` message. The frontend `isTaskThread()` predicate then
+//!      lists it in the Tasks tab next to manual runs (no UI change needed).
+//!   2. [`append_final`] — appends the run's final response (or failure reason)
+//!      as the closing `assistant` message after the turn completes.
+//!
+//! The *live* streaming (text/tool deltas + tool timeline) is not done here:
+//! [`task_dispatcher::run_autonomous`](super::task_dispatcher) wires the agent's
+//! `on_progress` into the web-channel `spawn_progress_bridge` with the broadcast
+//! client id `"system"`, so any client viewing the thread sees the run stream in
+//! real time — the same mechanism cron/welcome agents use.
+//!
+//! All writes are best-effort: a thread-store failure is logged and the
+//! autonomous run still proceeds headless, exactly as it did before this
+//! feature. The session is a surface over the run, never a gate on it.
