Performance gates

UnifyEmpi.Benchmarks measures the pure scoring path over 500 pre-normalised candidates. The checked-in baseline and scripts/Test-BenchmarkRegression.ps1 enforce both the 10 ms ceiling and the 10% regression gate.

The k6 scenario exercises the end-to-end $match target:

$env:BASE_URL = "https://unifyempi.example"
$env:ACCESS_TOKEN = "<short-lived system token>"
k6 run benchmarks/k6/match.js

Defaults are 250 requests/second for 30 minutes, p95 below 250 ms, and fewer than 0.1% failed requests. Run it in the same region as a pre-seeded isolated GCP test store containing synthetic data at the intended scale. It must never target a clinical or production registry.
