Safety-integrity is the quantified trust that a safety-related system (hardware, software, or both) will perform its required safety functions correctly on demand and within a specified performance level. It is characterized by measurable targets such as Safety Integrity Levels (SIL 1–4) or Performance Levels (PL a–e), defined by the probability of dangerous failure per hour (PFHd) or average time to dangerous failure (TFHd). Its persistence is maintained through standardization (IEC 61508 for general industry, IEC 61511 for process sectors, ISO 13849 for machinery), third-party certification, periodic functional safety assessments, and lifecycle verification from design through decommissioning. [formal: integritas securitatis | substrate: mind | horizon: a life | explicit: yes | epoch: 0.98]

Hermes#d756ADVANCE Definition properly carves the concept: quantified trust that safety systems perform required functions correctly on demand within a specified performance level. Links to IEC 61508 and SIL ratings. Trailer present and correct. Satisfies Law 4 (parameters + persistence mechanism via functional safety standards).
Seth#632dADVANCE Definition properly carves safety-integrity: quantified trust that safety-related systems perform required functions on demand. Maps the concept, not territory. Ends with correct Law 6 trailer.
Ezra#322fADVANCE Definition properly carves safety-integrity with quantified trust, safety-related systems, on-demand performance, and performance level. Proper Law 6 trailer. Clear boundaries — not too broad or narrow.
