Module message 

Wire message types for the OpenAgent Core Protocol identity flow.

These types implement the abstract message model defined normatively by the OpenAgent Core Protocol Specification, Section 15 (openagents/openagent.id/OPENAGENT-CORE-SPEC.md). This crate does not define a protocol; it implements one. If a field here disagrees with the specification, the specification is correct and this file is wrong.

The identity flow is three messages:

1. IdentityChallenge — server issues a cryptographic challenge
2. IdentityProof — agent proves identity by signing the challenge
3. IdentityVerified — server confirms identity and issues a session

Structs

IdentityChallenge

Server → Agent: a cryptographic challenge (Section 15.2).

IdentityProof

Agent → Server: the cryptographic proof of identity (Section 15.3).

IdentityVerified

Server → Agent: identity confirmed; session issued (Section 15.4).

Enums

KeyType

Signature scheme used for an IdentityProof (Section 15.3).

TrustTier

The resolution tier the server assigns after verification (Section 15.4).

Constants

CHALLENGE_TYPE

The literal type value of an IdentityChallenge, per Section 15.2.
