Add full Responses API endpoint alongside existing Chat Completions, with identical logging/tracking/cost pipeline. New: - internal/models/responses.go — request/response/stream types + ToUsage() bridge - internal/providers/openai_responses.go — OpenAI Responses/ResponsesStream Modified: - provider.go — Responses()+ResponsesStream() added to Provider interface - helpers.go — BuildOpenAIResponsesBody, parsers, SSE stream reader - circuit_breaker.go — CB wraps Responses, passthrough for stream - server.go — POST /v1/responses route + handleResponses handler - all non-OpenAI providers — stub methods with clear error messages Logging: ResponsesUsage.ToUsage() bridges to models.Usage, feeding same logRequest() -> DB insert -> dashboard WS -> client stats -> cost calc pipeline. No schema or logger changes needed.
