Runnable demos

Four patterns you can poke.

Checkpoints and interrupts, the depth where a crew starts to win, a Grok Build-style session list, and a Grok research desk. The three simulations run locally; live Grok research is unavailable in this edition.

Graph + HITL

A LangGraph-style state machine. The critic node interrupts. Approve to resume from the checkpoint, or reject to roll back to plan — intake is not replayed.
