Infrastructure Portability.
For Evidence That Has to Survive Migration.

Cloud migration to a new hyperscaler. Software replacement of a core system. Vendor migration after acquisition or contract loss. Application modernization onto a new architecture. Each of these is operationally expensive, but the deeper cost is rarely discussed: the cryptographic evidence produced by the prior system is almost always lost in the transition.

Logs are reformatted, identifiers are rewritten, certificates are reissued, signing keys are rotated, audit trails are exported into formats the new system doesn't natively verify. The institutional memory of what actually happened — who approved what, what policy applied, what controls were active — fragments at every migration boundary.

H33-74 is a 74-byte post-quantum attestation primitive that produces cryptographic evidence as a byproduct of normal operation. The primitive is portable, operator-agnostic, vendor-agnostic, and chain-agnostic. It travels with the data, the decision, or the workflow it attests.

When you migrate from AWS to Azure, the H33-74 receipts come with you. When you replace your AI orchestration stack, the receipts remain verifiable. When you switch from one blockchain anchor to another, the receipts re-anchor without losing provenance. When you change vendors entirely, the receipts are still cryptographically valid — independent of any vendor's continued cooperation.

Cloud migration: moving regulated workloads across hyperscalers, into sovereign-cloud regions, or into hybrid on-premises deployments. The audit trail that existed in the old environment must remain verifiable in the new one. H33-74 makes that automatic.

Software migration: replacing a core platform — EHR, ERP, LOS, claims-management, CRM, orchestration engine — without losing the audit history. The new system reads the H33-74 receipts and treats them as authoritative.

Blockchain migration: tokenized assets moving between chains, custody platforms moving between custodians, settlement infrastructure moving between rails. The evidence is independent of any one chain.

Vendor migration: post-acquisition consolidation, post-divestiture separation, post-contract switching. The departing vendor's records remain verifiable to the incoming vendor and to regulators.

Application modernization: monolith-to-microservices, legacy-COBOL-to-cloud-native, mainframe-to-API. Each architecture transition is a verification breakpoint that H33-74 eliminates.

CIOs running multi-year modernization roadmaps can commit to the modernization without committing to evidence loss. H33-74 lets the CIO architect the next platform without leaving the prior platform's auditability behind.

CISOs accountable for long-horizon security evidence (NIST CSF, ISO 27001, SOC 2, FedRAMP) need records that survive any infrastructure replacement. H33-74 is the cryptographic substrate for those records.

Chief Risk Officers managing model risk under SR 11-7, OSFI E-23, APRA CPS 230, FCA SS1/23 need model-governance evidence that survives model replacement and platform replacement. H33-74 binds the governance state cryptographically.

General Counsel preparing for regulatory enforcement, civil litigation, or M&A diligence needs evidence that is admissible, verifiable, and independent of any vendor's continued cooperation. H33-74 satisfies all three.

NSM-10, CNSA 2.0, NIST FIPS 203/204/205, the ENISA PQ migration roadmap, the Federal Reserve's interagency PQ guidance, ASD ISM, and UK NCSC have all mandated post-quantum migration on explicit timelines. Records signed only under classical primitives today will become evidentially weaker over the relevant compliance and legal time horizons — often 7–25 years.

H33-74 receipts are signed under three independent post-quantum signature families (ML-DSA, FALCON, SLH-DSA) by architectural construction. They survive the quantum transition that classical signatures will not.
