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).

Known limitations

• {"limitation": "In-process trust layer over the E25 fabric. No third-party agent, MCP server or A2A peer has consumed a CAIN trust object.", "status": "SCOPE"}
• {"limitation": "Hardware attestation adapters have no registered verifier here; every hardware result is UNKNOWN, never ATTESTED.", "status": "UNKNOWN"}
• {"limitation": "Zero-knowledge authorization proofs are not implemented.", "status": "NOT IMPLEMENTED"}
• {"limitation": "AuthZEN/COAZ/SPIFFE-SVID/continuous-remote-attestation are mapped; no external conformance run.", "status": "MAPPED"}
• {"limitation": "Evidence is signed with an ephemeral build key.", "status": "EPHEMERAL"}
• {"limitation": "No third-party review; behavioral anomaly recall unmeasured.", "status": "NOT REVIEWED"}
• {"limitation": "The scale run is a deterministic single-process model, not a fleet.", "status": "MODEL"}

CAIN-42 Evolution 26 -- Universal Machine Agency Trust Fabric#

Evidence measured from the real E26 objects. Start with CAIN42_E26_EVIDENCE_BUNDLE.json; one trust run is published in TRUST_RUN_MANIFEST.json; verify with verify_e26.py.txt (see REPRODUCTION.md). Status: TESTED library, pre-production; hardware attestation and ZK proofs are NOT implemented.
