gRPC protocol

This directory is the canonical source for vLLM's gRPC schema.

The schema is published to buf.build/vllm-project/vllm:

• A daily workflow publishes the latest Git main schema to the nightly label.
• The workflow can be run manually to retry nightly publication.
• Tags matching v* update the Buf main label and publish the corresponding release label.
• Buf commits and generated SDK versions are immutable and can be pinned by consumers.

Repository setup requires a BUF_TOKEN GitHub Actions secret with permission to create and push the public Buf module. Register the Prost and Tonic generated SDKs for the main and nightly labels once so subsequent pushes generate them automatically.
