dns_lookupResolve a DNS record via `dig` (A/AAAA/MX/TXT/NS/CNAME/SOA/PTR/CAA), optionally against a specific resolver and over plain DNS/DoT/DoHdnssec_checkQuery a known-validating resolver and report whether the AD bit is set (plain/DoT/DoH) — the only reliable way to confirm DNSSEC validation, since an RRSIG being present in a plain `dig` reply does not by itself prove anything validated itping_hostICMP ping (count clamped to 1-10)traceroute_pathHop-by-hop path/loss report via `mtr --report` (fixed cycles, not a live/continuous run)tcp_port_checkIs a TCP port open — a plain socket connect, not a port scanhttp_checkHEAD/GET a URL and report status, redirect chain, and latencyhttp_getGET a URL and return the body. Textual types only (`text/*`, JSON, XML, JavaScript, YAML, `+json`/`+xml`), capped at 1 MiB. Refuses loopback, link-local and cloud-metadata destinations, including via redirecttls_cert_checkFetch the certificate a host presents and report subject/issuer/validity/SANswhois_lookupWHOIS lookup for a domainasn_lookupASN + country-code lookup for an IP, or org info for an AS number, via Team Cymru's whois service — no API key or GeoIP database neededcurrent_timeCurrent date, time and weekday in an IANA timezone — the weekday is returned as data because deriving it from a date is arithmetic that fails silently. Also reports UTC and epoch, so it doubles as a clock checkhealth_checkVersion and which wrapped binaries (`dig`/`ping`/`mtr`/`whois`) are present on PATH
