About
The default brainstorming ceremony. Four rounds — initial positions, build and challenge, inversion (how would this fail?), and synthesis with commitments. The magic happens in rounds 3-4 after obvious ideas are exhausted.
Capabilities
- 4-round structure: initial → build → inversion → synthesis
- Blind initial ideation (no groupthink)
- Mandatory cross-referencing in later rounds
- Inversion thinking to surface blind spots
- Commitment extraction in synthesis round
