Return the complete intro request state machine transition graph. Each row is a directed edge: source_state → target_state, plus the event that triggers the move, which actor may fire it (ADMIN, REQUESTER, SYSTEM, REFERRER), action metadata, and event_label (human-readable). No input — returns the full graph in one call. To find valid next moves for a specific request: call intro_request_get_current_state first, then filter transitions where source_state equals that current_state and allowed_actor matches the caller's role.

Use when: Use to understand the intro request lifecycle — which states exist and which events move from one state to another (e.g. DRAFT → INTRO_REQUESTED via INTRO_REQUESTED_EVENT, DRAFT → DISCARD_DRAFT via DISCARD_DRAFT_EVENT). Call before intro_request_send_state_change_event whenever you are unsure what transitions are legal from the request's current state. Pair with intro_request_get_current_state: current_state tells you where the request is; this tool tells you where it can go next.

Behavior: read_only

workspace_id / user_id are injected from request headers.

Next steps (after this tool succeeds): [optional] [SUGGESTION] → call intro_request_send_state_change_event: After filtering edges from the request's current_state, fire the chosen event via intro_request_send_state_change_event.

Returns transitions[] with fields: source_state: From-state — the intro request must be in this state for the transition to be valid. Match against current_state from intro_request_get_current_state. target_state: To-state — where the intro request lands after the event succeeds. event: Event enum to pass to intro_request_send_state_change_event to trigger this edge. action: Internal action identifier for this transition (informational). allowed_actor: Role allowed to fire this event. Only suggest transitions the current user's role can trigger. event_label: Human-readable label for this transition — use when presenting next-step options to the user.

IMPORTANT: If the response contains more than one record, always present the options to the user and ask them to choose before taking any follow-up action. Do not act on all results automatically.
