The KXCO brand line is Proof at every crossing. This page sets out what each kind of proof shows, and where it stops. Here, proof means a record another party can check: a signature, a hash-linked entry or an anchor. Each shows something specific and limited. None shows that the underlying claim is true.
The standard
A published specification is presented as a specification, not as a product in use. Demonstrations and customer outcomes carry their own dated evidence.
A verification checks a specific record, not the claim inside it. It does not certify that a system is safe, and it is not regulatory approval.
Product by product
KXCO Round Table
Round Table records claims with their sources. Recording a claim does not make it true. Decisions stay with named people. Public maps use public data only.
KXCO Portcullis
A release signature shows which key signed the release and that the release has not changed since it was signed. It does not prove the software is secure. Portcullis Muster scores an AI agent's declared governance. It assesses declared posture, not run-time behaviour, and it enforces nothing. The free kxco-pq-scan covers JavaScript dependencies only.
KXCO Herald
A valid Herald signature shows which key signed and that the content has not changed since. Herald links keys to identities for domains and documents today; identity for people and AI agents is in development. Authority to act is a separate check.
KXCO Sovereign
KXCO is the software provider. The institution and its partners own the regulated service, permissions and availability.
KXCO Guildhall
Guildhall is software for running a deal. It is not an invitation to invest and does not replace the institution's own governance.
KXCO Hanse
Hanse is in development. Partners, jurisdictions and availability must be confirmed before any customer commitment.
KXCO Armature
An anchor shows that a record existed in a given form no later than the time it was anchored. It does not make the underlying claim true.
