This is H33-74 — the portable 74-byte post-quantum evidence primitive that produces and anchors operational proof — applied to DORA. The primitive is unchanged; only the application context differs, and the evidence it produces supports (does not by itself satisfy) the regulation. Digital Operational Resilience Act requires verifiable evidence of operational controls. H33-74 produces that evidence as a chain-portable post-quantum receipt that survives the systems and chains it was anchored to.
Digital Operational Resilience Act (European Union, financial entities) places obligations on organizations to demonstrate that operational controls were in place, that AI and automated decisions were governed, and that an audit trail exists for regulatory inquiry. Most existing audit-log architectures meet the letter of the requirement but produce evidence that is tied to the operator's current systems. If those systems change or fail, the evidence weakens.
DORA requires financial entities to demonstrate that ICT risk is managed, ICT-related incidents are reported, resilience testing is performed, and ICT third-party risk is monitored. The competent authority can request evidence of controls operating effectively across the full reporting period. DORA's reporting horizon (incidents, major changes, third-party arrangements) requires evidence that survives technology refresh cycles, vendor changes, and chain migrations.
DORA evidence must be reproducible to the competent authority on demand, often years after the events occurred. H33-74 receipts are cryptographically verifiable by the authority directly, without requiring the financial entity's original systems to be operational. The PQ signatures address long-horizon cryptographic survival; the chain-portable anchors address the long-horizon viability of any specific notarization chain. DORA's evidence requirements get longer-horizon protection without changing the entity's underlying ICT stack.
H33-74 is the same primitive across every regulation — only the crosswalk differs. Compare the sibling mappings for SOX and NIS2. Where ICT controls must be shown to stay true continuously, HATS records that ongoing control evidence on this same H33-74 substrate.
