Use the verbatim prompts at .flywheel/prompts/deep-review.md,
alternating Round A (random exploration) and Round B (cross-agent
review).
Run this on 1–2 agents who just finished a bead, not the whole swarm. Continue until two consecutive rounds from different agents come back clean.
If agents keep finding bugs after 4+ rounds, the real issue is a pattern — go back to bead space and create fix-beads for the bug class.
