TESTED

The claim

1269 of 1269 adversarial and conformance scenarios held; 252 of 252 invariants; mutation 12 of 12

Level TESTED is how far the evidence goes: TESTED means a test suite exercised it, LIVE means it was observed on the hosted system. Nothing is claimed beyond its level.

Verify it in your browser

Your browser downloads the bundle's SHA256SUMS manifest and the file(s) behind this page, hashes them with SHA-256 locally (WebCrypto), and compares. A match shows the record you are reading is the published one; it does not by itself prove who published it (see the signed claims registry and the bundle verifier for that).

Limitations of this bundle

• An in-process TESTED library; not hosted; not wired into the gateway, MCPGate or the clusters.
• Witnesses and the dispute engine run in the same process as CAIN: diverse code and separate keys, not separate organizations. No third party has verified any proof.
• CAIN-GIP carriers are in-process reference adapters; no protocol has a network wire implementation. Agent runtimes, model runtimes and workflow engines have no carrier (NOT IMPLEMENTED).
• Trust anchors are published in the same bundle as the proofs: a verifier checks internal consistency against them, not that they belong to a real operator.
• Postconditions are observations by a registered observer key; they say nothing about physical truth.
• World-state version and trajectory are recorded as UNKNOWN: E31 does not bind a world model.
• No trusted time source: validity windows use the issuer's clock; partition behaviour is not addressed.
• Hardware attestation UNKNOWN; zero-knowledge proofs NOT IMPLEMENTED; no external review.
• Scale rows are synthetic and in-process; the 100,000-proof row uses real crypto over synthetic content and the 1,000,000 row is hashing only.
• cain-json-v1 canonicalization is not RFC 8785 JCS.
