Complete documentation suite for Digital Key Framework: commercial framework, patent filing, academic whitepaper, and Brain-LACF v2 architecture. Model-agnostic behavioral control system with invariant validation, progressive regeneration, and guaranteed fallback. Built on LACF/AOED methodology. Four-pillar architecture: (1) Pre-optimization via few-shot learning and reward tokens (2) Progressive regeneration cycle (3 attempts, increasing strictness) (3) Real-time ontological filtering (Cockpit de Drift v1.3) (4) Guaranteed fallback with full audit trail v2.0 adds Brain LACF: deterministic pre-classification (sklearn TF-IDF + LinearSVC, 100% accuracy on 5810 samples, <1ms inference) before LLM generation. Results: 80% pristine rate, 100% success rate, 0.6% fallback rate on 50 critical ethical questions.
