fix(tui): cannot navigate into grandchild sessions from subagent view #23782
Description
Description
In the TUI session tree, when a sub-agent spawns its own child (grandchild session), pressing down or clicking to navigate into the grandchild session does nothing. Navigation into child sessions only works from the root session level.
Steps to reproduce
- Start a session that spawns a sub-agent
- Navigate into the sub-agent session (this works)
- The sub-agent spawns its own child session (grandchild)
- Press down / try to navigate into the grandchild → nothing happens
What's happening
moveFirstChild() and moveChild() in session/index.tsx use children() to look up sessions, but children() only returns the root session's direct children. From a sub-agent context, the grandchild sessions are not in that list, so navigation fails silently.
