Building CrewAI Flows on crewai 1.15.x: structured (Pydantic) vs dict state and state.id, @start/@listen/@router wiring, or_/and_ semantics, router labels vs method names, @persist (correct import, where it stores state, restore_from_state_id), checkpointing with CheckpointConfig, @human_feedback and HumanFeedbackResult.feedback, plot(), calling crews and agents from flow methods, kickoff inputs, and the `crewai create flow` scaffold. Use when writing or debugging a Flow subclass or main.py with `from crewai.flow import ...`, when a listener never fires or fires twice, or when you see errors like "listen condition 'x' references the handler name 'x'", "cannot import name 'persist'", "'StateWithId' object is not subscriptable", "Flow state model must have an 'id' field", "--inputs requires a declarative flow definition", "invoked synchronously from within a running event loop", or HumanFeedbackCollapseError.
