v2.5.3

Adapter Lab II — workflow / enterprise adapters as docs + examples (no wire-format
change). Scope: prd-v2.5.3-adapter-lab-ii.md.
npm @asap-protocol/* packages remain at 2.4.1.

Added

• Workflow connectors: OpenAPI → ASAP skills for n8n-/Activepieces-shaped workflow
  HTTP APIs — guide +
  examples/workflow_asap_connector/ (Compliance Harness v2 score 1.0).
• Automation connector security: production baseline for OpenAPI-backed connectors
  (guide).
• Microsoft Agent Framework: research / experimental interop guide
  (guide); no .NET SDK / NuGet sample.
• NeMo Agent Toolkit: experimental Path A stdio demo
  (guide,
  examples/nemo_agent_toolkit_asap/); Path C third-party plugin remains deferred.
• Docs / web surface: MkDocs Adapters + Lab II nav; marketplace WhatsNew ribbon and
  developer-experience CTAs for Lab II guides.

Fixed

• Invalid envelope JSON-RPC errors: URN / structure validation failures return
  JSON-safe -32602 with validation_errors (no longer escalate to -32603 when
  Pydantic embeds ValueError in ctx).
• MCP Auth Bridge example client: self-contained path captures the demo Agent JWT
  from the spawned child stderr (cross-process paste no longer required).
• ASAPClient.health_check: base_url defaults to the client's HTTP base URL.

Security (deps)

• Override setuptools>=83.0.0 for PYSEC-2026-3447 (transitive build/tooling path).
  See SECURITY.md.

Migration

• v2.5.2 → v2.5.3: See migration guide.
  No breaking wire-protocol changes; adopt new guides/examples as needed.
