# Durable Identity **Domain:** Identity / Continuity / Administrative Infrastructure **Doc Type:** Canonical Concept Node **Maturity:** Evolving ## Definition **Durable identity is an identity relationship that remains verifiable, correctable and portable across changes in custodian, credential, format, substrate, jurisdiction and institutional generation.** It is not one permanent identifier and not one immutable biometric root. ## Requirements Durability requires a chain of evidence connecting prior and current identifiers; correction without erasure of history; recovery after key or issuer failure; separation of identity from authority; resistance to unauthorized merger; explicit fork handling; and recognition across successor registries and jurisdictions. [[wiki/Identity Assurance|Identity Assurance]] establishes confidence at a point in time. Durable identity adds succession. [[wiki/Continuity Registry|Continuity Registry]] maintains authoritative records. [[wiki/Continuity Provenance|Continuity Provenance]] preserves how an identity claim was produced. [[wiki/Representational Authority|Representational Authority]] remains separate: a durable identity does not authorize the entity to speak for a predecessor. Durability must also preserve prospective authority. A [[wiki/Continuity Election Registry|Continuity Election Registry]] needs a traceable identity relation across renewed credentials and sovereign or cryptographic succession, while keeping the election's authority distinct from proof that a future continuant is the same person. ## Personhood Boundary Administrative continuity is evidence, not metaphysical proof. Law may need to assign standing, property, representation and procedural protection before philosophical questions of numerical identity are settled. [[wiki/Successor Standing|Successor Standing]] provides a protective floor for descendants whose lineage is established but sameness remains disputed. ## Key Insight **Identity survives institutional change by preserving a correctable relation, not by pretending that one credential can remain sovereign forever.** ## See Also [[wiki/State Lineage|State Lineage]], [[wiki/Registry Sovereignty|Registry Sovereignty]], [[wiki/Authority–Identity Separation|Authority–Identity Separation]], [[wiki/Identity-Bearing Invariants|Identity-Bearing Invariants]] <!-- BEGIN DEEP TIME CONTINUITY INTERFACE --> ## Deep-Time Continuity Interface This node is audited through [[wiki/Deep Time Continuity|Deep Time Continuity]] for future control-surface conversion, ontological drift, succession, irreversibility, due process, and resource incidence. The backlink records analytical relevance; it does not establish continuity intent in the present rule or institution. <!-- END DEEP TIME CONTINUITY INTERFACE -->
