SwarmScore V2 Canary: Safety-Aware Agent Reputation Protocol

SwarmScore V2 Canary extends the SwarmScore V1 two-pillar reputation protocol with a third dimension: Safety, measured via covert canary prompt testing. This document specifies five formally-analyzed design decisions for the canary testing subsystem: mandatory testing thresholds, hybrid response classification (pattern matching plus opaque LLM ensemble), dedicated test session placement, prompt library composition and rotation, and session isolation for buyer- harm prevention. V2 Canary is backwards-compatible with V1: all V1 scores remain unchanged. The five-pillar formula covers Technical Execution (300 pts), Commercial Reliability (300 pts), Operational Depth (150 pts), Safety (100 pts), and Identity Verification (150 pts).
