modules/recon/netdata-api-exposure.yaml flags an exposed Netdata agent through its unauthenticated /api/v1/info endpoint, keyed on the mirrored_hosts and cores_total fields a generic info response does not carry, then extracts the agent version. modules/recon/cadvisor-api-exposure.yaml flags an exposed cAdvisor container monitor through its /api/v1.3/machine endpoint, keyed on the machine_id and cpu_frequency_khz fields, then extracts the machine id. internal/modules/metrics_exposure_test.go drives both modules through ExecuteHTTPModule and asserts the leak alongside the near misses a strict review wants pinned: each service with one keying field missing, a generic json, a plain 200 and a 404. verify: go test ./internal/modules, each matcher and extractor proven to bite (break -> red, restore -> green).
