Protocol Design

The site keeps the following versioned design documents:

1. NNRP/1-preview1
2. NNRP/1-preview2
3. NNRP/1-preview3
4. NNRP Protocol Conformance Suite Design
5. NNRP OpenAI-Compatible API Profile
6. vLLM NNRP Adapter Design
7. NNRP/1-preview4

Index notes:

1. v1-preview1 captures the minimal runnable protocol skeleton.
2. v1-preview2 captures the preview2-stage design freeze for the richer data plane, typed payloads, and multi-transport binding. The emitted code-level wire identity frozen there is NNRP/1.0.
3. v1-preview3 captures the profile-neutral public layer and the multi-session model.
4. conformance-suite defines the positioning, versioning strategy, test layering, and implementation boundary of the cross-version protocol conformance suite.
5. openai-compatible-profile defines the frozen API profile for carrying OpenAI-compatible AI API semantics over NNRP sessions, submissions, result streams, cancellation, and diagnostics.
6. vllm-nnrp-adapter defines the first adapter architecture for implementing the openai-compatible/1 profile against vLLM, with the adapter positioned as NNRP compatibility infrastructure rather than a vLLM performance accelerator.
7. v1-preview4 defines the runtime object, control-frame, and wire-level conformance direction for workloads where scheduling, partial artifacts, deadlines, and heavy object movement dominate the protocol boundary.
