This paper introduces the Cognitive Operations Protocol (COP), a five-protocol diagnostic pipeline (Input Sampling/State Encoding/Diagnostic Judgment/Referral/Feedback Calibration) that outputs five triage states (RESOLVE/MIXED/FREEZE/UNKNOWN/REFER). Key innovation: FREEZE as a legitimate, structured output rather than system failure. Framework only — no implementation parameters disclosed. English preprint.
