HAP 0.2.0

Changelog

0.2.0-rc.2

• Run interface conformance against the agent command or endpoint declared in
  hap.yaml.
• Add runtime endpoint and scenario overrides for local conformance testing.
• Require HAP 0.2 handshake acknowledgement and terminal-result correlation.
• Support both descriptor-relative and PATH-resolved process commands.

0.2.0-rc.1

• Replace the 0.1 proof-of-concept manifest with a strict HAP agent descriptor.
• Add process/JSONL, HTTP, WebSocket, and HAP-declared A2A 1.0 interfaces.
• Define canonical handshake, Task, Event, Result, and cancellation messages.
• Add measured-or-unavailable usage, actual cost, and W3C trace context.
• Add strict extension, credential, capability, and lifecycle semantics.
• Add descriptor, message, and cross-interface conformance fixtures.

This release intentionally provides no 0.1 compatibility layer.

HAP Agent Protocol v0.2.0-rc.2

Corrects the conformance CLI so interface checks invoke the command or endpoint declared by the agent instead of an internal simulated transport.

Also validates HAP 0.2 WebSocket handshakes, terminal-result correlation, descriptor-relative and PATH-resolved Process commands, and adds endpoint/scenario overrides for local testing.
