QVTM / Continuity patterns
Start with the change — then see where it matters.
QVTM is horizontal infrastructure. Six recurring patterns cover the fundamental ways an established trust relationship has to survive change; industry examples show where each pattern creates distinct operational value.
01
Replacement & succession
Prove that a new device, identity, key holder or service is a coherent successor — not an unexplained new trust origin.
Explore →02
Recovery without trust reset
Recover access or authority while preserving evidence that explains why the recovered state belongs to the earlier trusted history.
Explore →03
Cryptographic migration
Change keys, algorithms and deployment profiles without discarding the evidence that connects earlier and later trust states.
Explore →04
System & service migration
Move a trusted role across clusters, clouds, CI systems or service endpoints without assuming infrastructure identity equals relationship identity.
Explore →05
Offline & delayed synchronization
Preserve continuity evidence across disconnected periods and reconcile it when authorized systems can communicate again.
Explore →06
Authority & delegation change
Track how human, organizational or delegated authority evolves while leaving the actual authorization semantics to the integrating system.
Explore →Why six? Each pattern represents a different axis of change: actor, recovery path, cryptography, infrastructure, connectivity, or authority. We add another only when it describes a materially different continuity problem—not to inflate the catalog.
Why patterns, not verticals
One protocol problem can create different business value in different industries.
A device replacement in OT is about preserving a maintenance relationship across long asset lifetimes. In finance, the same class of transition can affect confidence in an approver before a high-value action. In software supply chain, succession may explain why a new release signer legitimately follows the old one.
The protocol primitive is horizontal; the evidence, complementary controls and operational benefit are domain-specific. The tags show breadth; the examples inside each pattern prove the differences.
