role_info_succeeds_with_role	Role present → exports prompt
agent_info_errors_when_no_agent	No agent → error
rag_info_errors_when_no_rag	No RAG → error
use_role_obj_errors_when_agent_active	Agent blocks role assignment
exit_rag_clears_rag	exit_rag() sets rag to None
discontinuous_last_message_sets_continuous_false	Marks last message non-continuous
discontinuous_last_message_noop_when_none	No last message → no-op
before_chat_completion_sets_last_message	Creates LastMessage with empty output
role_like_mut_returns_none_when_empty	No active scope → None
role_like_mut_returns_role_when_only_role	Role only → returns role
role_like_mut_prefers_session_over_role	Session takes priority
working_mode_cmd	CMD mode flags correct
working_mode_repl	REPL mode flags correct
session_file_returns_yaml_path	Correct .yaml suffix

Observations for future iterations

1. Rag struct has no Default: Rag requires an AppConfig, name, embedding model, and HNSW index. Can't create test instances without heavy setup. RAG-related state tests (state with RAG, exit_rag with actual RAG) deferred.

2. role_like_mut priority is session > agent > role > None: The session-over-role priority is verified. Agent priority can't be easily tested without agent init (filesystem).

3. StateFlags is a bitflags type: Tested empty, individual flags (ROLE, SESSION_EMPTY), and combinations. The SESSION flag (non-empty session) requires adding messages to a session which needs more setup — deferred.

4. info() and sysinfo() require model provider config: These format system info strings that include model details. Testing requires a valid model provider configuration.

5. The RequestContext test file now has 51 tests spanning iterations 1, 4, 5, 7, and 8. It's the most heavily tested module, which matches its role as the central state container.
