System status / Regression corpus

Tariff regression corpus

Every tuple in config/tariff_regressions.yml runs against TariffResolutionService.resolve — the same code path the public API uses. Failures block /status from returning healthy and emit warnings in API responses for the affected HTS/origin pairs.
