A/B VARIANT // EVIDENCE TERMINAL

PROVENANCE-FIRST HERO.

This static variant keeps the same brand system while testing denser proof above the fold: official upstream, current candidate CI, calibrated CI, runtime path, and source links before the archive.

RINHA 2026 // .NET 10 NATIVEAOT

FRAUD SIGNAL
UNDER LOAD.

A public proof dossier for a raw HTTP/1 fraud scorer: official upstream history, current CI candidate evidence, and the runtime path that keeps the hot loop small.

RUNTIME TRACE

THE HOT PATH IS A SHORT PATH.

  1. 01 ingressk6 / judge reaches :9999

    The public boundary is the yolo load balancer, not ASP.NET Core.

  2. 02 transportfd-pass fanout to two APIs

    The LB sends accepted client fds over Unix control sockets; APIs serve the client socket directly.

  3. 03 parseminimal field extraction

    The app scans enough JSON to build the 14-dimensional fraud vector.

  4. 04 scoreIVF first pass, bounded repair

    The default clean lane uses rounded int16 IVF plus repair; bucket/hybrid modes stay available for experiments.

  5. 05 respondprebuilt bytes out

    The decision returns a small HTTP response without framework ceremony.
