1-to-1 Architecture Match with GG Loop (anti-cheat-sdk): Every downlink frame is cryptographically signed in browser memory via Web Crypto HMAC-SHA256, evaluated against sliding-window Z-score & deterministic threshold bounds, and buffered into single-roundtrip PostgreSQL unnest() batch arrays.
Why unnest() over standard ORM inserts? Instead of executing 50 separate network roundtrips per second (N+1 bottleneck), packing typed columnar arrays ($1::timestamptz[], $2::text[], $3::float8[], $4::text[]) into a single parameterized PostgreSQL unnest() transaction cuts write latency by >85% while maintaining strict ACID auditability.
