ChathuniPG/DPF-Architecture: DPF Architecture: Context-Aware Authorization Update (v1.0.1)

Official implementation of the Deterministic Privacy Firewall (DPF) architecture. What's New in v1.0.1: Context-Aware Egress Patch: Updated the Post-Generation Filter to dynamically respect Role-Based Access Control (RBAC) boundaries. The egress filter now intelligently bypasses redaction during authorized, isolated dyadic channels (Private Mode), while strictly enforcing Zero-Trust redaction in globally shared environments (Group Mode). Core Artifacts Included: This release contains the core deterministic enforcement engine, the dual-index memory orchestrator, and the complete N=500 evaluation dataset (400 adversarial RAG vectors and 100 benign utility prompts) required to reproduce the ablation study.
