Agent Runtime v0.3.1

Agent Runtime v0.3.1 strengthens the boundary with Agent2Agent Protocol. This patch release treats A2A as the peer-agent interoperability reference while keeping Agent Runtime responsible for internal execution facts, task attempts, local permissions, evidence, and recovery.

Highlights

• Adds official A2A sources from the protocol specification, Google Developers Blog, Linux Foundation announcement, and project repository.
• Clarifies that A2A peer tasks map to local task wrappers or remote task refs, not replacements for local task_id and attempt history.
• Expands remote channels with native_protocol, peer-agent roles, native peer ids, A2A task/context ids, and peer task lifecycle events.
• Maps A2A Agent Cards, messages, artifacts, streaming, push notifications, and in-task authorization into runtime facts.
• Adds anti-patterns for losing peer boundaries, treating messages as durable outputs, and marking disconnected peer work as completed.

Compatibility

v0.3.1 is compatible with v0.3.0. It does not add a required transport or turn Agent Runtime into an A2A implementation. Implementations can expose an A2A adapter, but the adapter should preserve both local runtime ids and remote A2A ids.
