IPPAN L1 publishes cryptographic anchors that can be independently checked against signed evidence bundles. This page records what has actually been demonstrated — and, just as explicitly, what has not been claimed.
External verification has been demonstrated in a controlled off-host dry run (2026-06-11). This means an exported evidence bundle was verified away from the producing host and matched the public anchor gateway: 121 anchors, latest sequence 120, checksum integrity, dense sequencing, no duplicates, and commitment re-derivation all passed, with gateway result MATCH.
This is not a third-party audit, legal certification, financial audit, or carbon-credit certification. The dry run was controlled and operator-executed; independent third-party verification is the next step on the roadmap.
Evidence bundle exports are operator-signed: each export carries a detached signature over its checksums, verifiable against a published operator public key delivered out of band. The latest signed export (2026-06-11) covers 121 anchors (sequence 120) with freshness FRESH_MATCH against the public gateway.
The signature proves an export is the one the operator produced — it does not by itself certify anchor authorship or any business claim.
