Constitutional Enforcement Kernel (CEK)

Validates every block against ten constitutional laws before finalization. Located in crates/amun-constitutional-enforcement/src/lib.rs.

Consensus Engine

Round-based BFT consensus with Proposal, Prevote, Precommit, and QC Formation phases. Located in crates/amun-consensus-network/src/engine.rs.

Evidence Root System

Chains all constitutional proofs across blocks via Blake3 recursive hashing. N129.4 guarantees tamper detection.

Validator Identity (N105)

Ed25519 certificate chains with genesis authority verification.

ChainStore

Append-only B-tree store with crash recovery and snapshot support. Located in crates/amun-chain-store/src/store.rs.
