- **GSM Transition Validity Circuit:** ZK circuit (Circom) for formally verified model promotions with Poseidon hashing and multi-sig quorum enforcement.
- **SIP v3.0 Protocol:** Formal TLA+ specification for federated supervisory intelligence with adversarial scenario walkthroughs and model-checking guides.
- **Regulatory Engagement Pack:** Comprehensive Phase 1-3 sandbox program, Verifier Node CLI Reference, Orientation Guides, FAQs, and advanced rehearsal scripts.
- **Sandbox Exit Dossier:** 20-section dossier including External Audit Report (Sec 13), Board-Level Final Assurance (Sec 14), and a 13-slide briefing deck with speaker notes and Q&A.
- **Strategic Roadmap:** Phase 2-3 Posture Pack Strategy and Compliance Mapping Matrix for EU AI Act, Basel SR 11-7, and DORA.

All artifacts have been verified against SR 26-2 and EU AI Act GPAI standards. CI fixes for Deno, Netlify, and Markdownlint are integrated.
