/**
 * OpenAI Responses HTTP wire-format ↔ omp Context bridge for the auth-gateway.
 *
 * Inbound: parses `POST /v1/responses` request bodies into a {@link ParsedRequest}.
 * Outbound: encodes omp's {@link AssistantMessage} (and event stream) back into
 * the documented `response.*` SSE taxonomy or the non-streaming JSON shape.
 *
 * Spec: https://platform.openai.com/docs/api-reference/responses
 * Inverse direction (source-of-truth for item shapes): ../../providers/openai-responses.ts
