CalDAV and CardDAV checkers sharing a single Go module. Discovery follows RFC 6764 (/.well-known + SRV/TXT), authenticated probes cover principal, home-set, collections and a minimal REPORT query on top of go-webdav. Common shape in internal/dav/; CalDAV adds a scheduling rule. Surfaces its context URL (and each secure-SRV target) as TLS endpoints via the EndpointDiscoverer interface, so the dedicated TLS checker can pick them up without re-parsing observations. HTML report foregrounds common misconfigs (well-known returning 200, missing SRV, plaintext-only SRV, missing DAV capability, skipped auth phase) as action-item callouts before the full phase breakdown.
