This paper introduces the P-MATRIX Runtime State Representation: an externalized coordinate system that captures the operational posture of an autonomous agent at a single point in time. The representation consists of four evaluation functions, two composite scores, a discrete operating mode, and a risk classification level, all encoded in a single JSON record with twelve formally defined invariants. The format is non-executive by design: it specifies state, not action or control. Grounded in Korean Patent Application No. 10-2025-0216047.
