Specifications

ECZ-ID specifications define the structure, resolution behaviour, and validation logic for all identifiers, passports, and resolver outputs. These specifications are deterministic and resolver-enforced.

Resolver behavior is governed solely by these specifications. User interfaces, consoles, directories, or downstream systems are non-authoritative.

Temporal Resolution Requirements

For ECZ-ID to support deterministic enforcement across time, the system MUST satisfy the following requirements.

1. Historical State Reconstruction

The system MUST support deterministic reconstruction of authoritative identity, authority, and passport state as it existed at a specific point in time.

This requires that:

• Legally relevant state transitions are recorded in an append-only, non-overwriting manner
• Historical state can be re-resolved independently of mutable storage systems
• Reconstruction does not depend on narrative interpretation

These requirements are met through ledger-bound canonical recording (LedgerCore™).

2. Current Validity Determination

The system MUST enable deterministic determination of whether an identifier or passport is active and valid at the moment of reference.

This requires that:

• Current validity is distinguishable from historical correctness
• Validity is resolver-derived at time of query
• No inference of continuous observation is implied

These requirements are met through present-tense resolver evaluation (PulseGuard™).
