  This meeting first reviewed the proposal to support multiple DID
methods—including did:wba, native did:web, and did:webvh—through a
DID-method-agnostic Agent Identity
  layer. Participants were invited to review the related GitHub pull
request, including the method-specific resolution and validation
requirements and the did:webvh
  verifiable-history checks.

  Multi-method DID pull request:
  https://github.com/w3c-cg/ai-agent-protocol/pull/43

  The meeting then discussed Sean's provisional open verifiable agent
interoperability model. The proposal explores how DID-based agents could
interoperate with agents
  or workloads using OAuth client metadata, workload identity, PKI, and
related cryptographically verifiable identity mechanisms. It separates
identity, authentication,
  authorization, trust evaluation, messaging, and service invocation, and
considers RFC 9728 protected-resource metadata as part of a common
authorization flow.

  Participants supported the interoperability objective while emphasizing
the need for a focused scope, concrete adapter prototypes, end-to-end
demonstrations,
  performance and complexity analysis, security evaluation, and clear
development milestones. The group also discussed whether the eventual
output should be a normative
  standard, community best practice, architectural blueprint, reusable
implementation framework, or a staged combination of these.

  We welcome any comments on the minutes, the multi-method DID pull
request, or the broader interoperability architecture discussed during the
meeting.

  Best regards,
