Architecture record

The system architecture, the truth mechanisms and the truth RWA architecture, published as plain files, hashed into one manifest, and anchored so the design itself is on the record.

Merkle root

Verification recomputes SHA-256 of every listed file from what this site serves and compares it to the manifest. The Merkle root uses keccak256 over sorted pairs and is recomputed with the open build script.

How to recompute the root

Download the files, hash each with SHA-256, take keccak256 of each hash, sort, pair-hash with keccak256 (smaller value first) until one remains. The build script is public: tools/build-manifest.mjs. Compare with the root stored on Base by anchorHistory at the contract listed in the manifest.
