Lines 455 to 468 in 19ff926

	def _restore_context(self, session_id: str, context_data: Dict[str, Any]) -> bool:
	"""Restore session context"""
	try:
	session_file = self.checkpoint_dir.parent / f"{session_id}.json"
	if session_file.exists():
	with open(session_file, "r", encoding="utf-8") as f:
	session_data = json.load(f)
	session_data["scope_data"]["SESSION"] = context_data
	session_data["last_checkpoint"] = datetime.now(timezone.utc).isoformat()
	with open(session_file, "w", encoding="utf-8") as f:
	json.dump(session_data, f, indent=2, ensure_ascii=True)

Restore session context from wrong directory

The recovery path looks for the persisted session state in self.checkpoint_dir.parent / f"{session_id}.json", i.e. RUNS/<session>.json. Session files are actually written by SessionManager under RUNS/sessions/<session>.json (see SessionManager.__init__). As a result _restore_context never finds the session file and always returns False, causing recover_session to report FAILED/PARTIAL even when valid checkpoints exist. Use the same RUNS/sessions path here to restore the context.
