+//! Discovers subagent threads that belong to a primary thread by walking spawn-tree edges.
+//!
+//! When the TUI resumes or switches to an existing thread, it needs to populate
+//! `AgentNavigationState` and `ChatWidget` metadata for every subagent that was spawned during
+//! that thread's lifetime. The app server exposes a flat list of currently loaded threads via
+//! `thread/loaded/list`, but the TUI must figure out which of those are descendants of the
+//! primary thread.
+//!
+//! This module provides the pure, synchronous tree-walk that turns that flat list into the filtered
+//! set of descendants. It intentionally has no async, no I/O, and no side effects so it can be
+//! unit-tested in isolation.
+//!
+//! The walk starts from `primary_thread_id` and repeatedly follows
+//! `SessionSource::SubAgent(ThreadSpawn { parent_thread_id, .. })` edges until no new children are
+//! found. The primary thread itself is never included in the output.
