1. Quantified Blast Radius and Default-Action Escalations
Rather than streaming noisy terminal logs into chat, Brevio Harness enforces a strict weekly interrupt budget. High-risk changes touching billing, authentication, or database migrations emit a structured decision card stating the exact file blast radius, the cost of waiting, the automatic fallback action on timeout, and 1-tap controls ([Approve], [/hint], [/rule]).
