# { "Depends": "py-genlayer:1jb45aa8ynh2a9c9xn3b7qqh8sm5q93hwfp7jqmwsfhh8jpz09h6" } """ DracoProof: Autonomous AI Covenant & Milestone Adjudication Protocol ===================================================================== DracoProof is an on-chain verification engine for service-level covenants, qualitative milestone deliverables, and automated protocol escrow release. Core Architectural Invariants: 1. Frozen Covenants: Covenants start as editable drafts and become permanently immutable once frozen by the creator. 2. Evidence Decoupling: Deliverables are registered as external HTTP/HTTPS references with provenance hashes and category classifications. Registration does not imply satisfaction. 3. Storage Isolation: Non-deterministic closures capture strictly copied plain memory values, preventing GenVM storage mutation bugs. 4. Decisive-Field Equivalence: Multi-validator consensus in run_nondet_unsafe matches structured decisive verdict keys, tolerating natural prose variations in explanatory summaries. 5. Fail-Closed Outcomes: Any unavailable source or unverified criterion fails closed to INSUFFICIENT_PROOF or MILESTONE_BREACHED. 6. Composable Interoperability: Exposes is_covenant_satisfied() for downstream smart contracts to safely gate automated token escrows and payouts.
