Proof matrix

Every row is a signed proof of a real run.

A standard that says it runs everywhere has to show it. Each row below is a SignedProofCell: an Ed25519 signature over the canonical form of a run, naming the attestation and energy receipt that run produced — and the attestation itself verifies. The signature binds the cell's contents and the run it references; it does not, by itself, prove the host's OS or cloud, which are recorded as the operator ran them. What a host cannot demonstrate is marked unavailable, never faked.

This published matrix is signed with the project's development key, so it is operator-asserted: re-verify it yourself with the command below rather than trusting this page. An operator running the harness in production signs with their own key.

Check it yourself

The ledger is the artifact. Each cell carries its own public key and signature; the verifier recomputes the canonical preimage and checks the signature — no trust in this page required. The browser cell was minted by a wasm32 build of the standard's core running inside a headless browser isolate, and it verifies under the very same native verifier as every other row.
