Semantic Identity Drift
Semantic Identity Drift occurs when a system continues to operate under a decision that is no longer the same decision.
Key property
Drift is independent of correctness, performance, and certification success. A system may produce valid outputs, meet KPIs, and pass audits while assumptions are false, scope has shifted, or authority has expired.
Structural cause
Drift occurs because decision identity is often not enforced during runtime. Without explicit identity models, closure checks, and review logic, systems can continue to act on stale mandates.
Detection stack
- DIP for identity definition
- DCF for continuous legitimacy
- DASR for stability and exposure measurement
