Control vs Data Plane Split
The database is an operational index, never the source of cryptographic truth. All provenance stems from agent-signed hash chains and on-chain Merkle roots.
Transactional Outbox Engine
Asynchronous worker claiming, lease expirations, idempotent retries, and reconciliation ensure Solana and Irys commits survive network outages.
Self-Contained Portable Receipts
Any independent verifier can validate a receipt offline using TweetNaCl and SHA-256 without ever communicating with the PROVN backend.
