atomic-agent/src/turn/session.rs:496–519

Load a session by ID. Returns `Ok(None)` if the session file doesn't exist (not an error). # Errors Returns `AgentError::SessionIdInvalid` if the ID contains path traversal characters. Returns `AgentError::SessionLoadFailed` if the file exists but can't be parsed.
