Briarwood's diagnostic-driven iteration loop. Use when the user wants to execute a multi-cycle improvement pass with measurement at the end (e.g., "execute Cycles K''/K'''/M'/O", "ship the followup #1 stack", "run the next §3.11 cycle"). Encodes the proven workflow from the 2026-05-03 session that shipped 30 commits and dropped bug_loss_rate 79.5% → 69.9%. Trigger when the user references a NEXT_CYCLES_HANDOFF doc, asks to execute a roadmap cycle, or asks to follow up on a measurement that surfaced specific failure modes.
