 - [Phase 12]: Shodan/Censys/ZoomEye use bare keyword queries; Censys POST+BasicAuth, Shodan key param, ZoomEye API-KEY header
 - [Phase 12]: RegisterAll extended to 28 sources (18 Phase 10-11 + 10 Phase 12); cloud scanners credentialless, IoT scanners credential-gated
 - [Phase 13]: GoProxy regex requires domain dot to filter non-module paths; NuGet projectUrl fallback to nuget.org canonical
+- [Phase 13]: KubernetesSource uses Artifact Hub rather than Censys/Shodan dorking to avoid duplicating Phase 12 sources
+- [Phase 13]: RegisterAll extended to 32 sources (28 Phase 10-12 + 4 Phase 13 container/IaC)
