What

Claude Code adds a new reason, released_false_child_silent, to the reasons it records when releasing a held session in the connection to a runner. When a result arrives and the turn is not being held open, it now also marks the model's turn as ended.

Why

This is part of how sessions handle child processes that go quiet.
