CounselOS Contract Assurance
Public verification service

Verify the receipt, not the vendor.

Check whether a contract assurance receipt is cryptographically intact, bound to one manifest, signed for the correct purpose, and active in the current global status list.

  1. 1
    Signature purpose

    Attestation, selective presentation, and lifecycle status use separate public keys.

  2. 2
    Manifest binding

    The signed layers must commit to the same content-addressed assurance record and opaque slot.

  3. 3
    Current lifecycle

    The verifier refreshes the signed status list without looking up a person, company, or contract.

Receipt verifier

Paste a receipt bundle or choose a JSON file. Contract files are not accepted.

No account required

Accepted shapes: a receipt bundle, a hosted verify request, or a published CounselOS test vector. Maximum verification request: 64 KiB.

Ready for a receipt.

A precise trust boundary

A successful result proves integrity, provenance, declared policy execution, and current lifecycle for the disclosed claims. It does not prove that a contract is legally correct, commercially wise, or semantically complete.

Private reasoning
Remains sealed in each party’s tenant.
Public object
Contains signed commitments and selective disclosures.
Verification path
Open keys, published vectors, and an SDK-first protocol.
