# 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.**

## 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.
