SYSTEM TOPOLOGY

Transport Path

GET /ready

The standalone yolo load balancer accepts port 9999 and forwards raw HTTP to two API containers through Unix Domain Sockets. The app parses enough HTTP/1 to satisfy the Rinha workload.

Latency path [||||||||||||||||||..] tuned

Fraud Decision

POST /fraud-score

Manual JSON parsing extracts only the required fields, vectorizes into 14 dimensions, scores with rounded int16 IVF, and writes one prebuilt HTTP response.
