Latticra is an evidence-bound systems substrate for Linux-era and AI-era computing. Its purpose is to make system actions, automation, tool execution, and agentic workflows safer through deny-by-default authority, contract-first validation, cryptographic verification, no-effect reporting, runtime gating, and auditable evidence.

Experimental C cryptographic sealing core for Latticra using libsodium: XChaCha20-Poly1305, BLAKE2b, and Ed25519 for authenticated encryption, transcript hashing, signatures, and verifiable seal identifiers.

Evidence-bound systems architecture for local authority, receipts, reports, and future runtime boundaries.
