This service is the central coordinator for Cosmos Evaluator evaluations. It takes a single HTTP request, discovers every available checker (e.g. objects, attribute verification, and hallucination), dispatches them in parallel — including per-camera fan-out and cross-camera dependencies — and aggregates their results into a single HTTP response. It handles retries with backoff when checkers are saturated, records a full audit trail of every request and checker job, and exposes a simple submit-and-poll API so callers never need to know which checkers exist or how they run.
