Pure stdlib. Implements the spec's core: enrollment (single-use tokens), profile (SPKI pin, only real capabilities advertised), sessions with the §2.4 HKDF-SHA256 key schedule; UDP data plane with the 32-byte ELT1 header, 4-byte HMAC gate, 1024-wide anti-replay window, ECHO_RESP with observation block, TIMESYNC, and the §3.4 anti-amplification cap. Wire format has tests (roundtrip + silent-drop cases); enroll→profile→session smoke-tested live. Modes: container (autodetect /.dockerenv|/run/.containerenv|cgroup, or --docker/ECHOLOT_DOCKER=1; config via ECHOLOT_* env; distroless image; network_mode host required — Docker NAT would falsify observed sources) and native (--install-systemd/--uninstall-systemd with a hardened unit, opt-in --self-update from Gitea releases; refused in containers). CI: tests on any server/ push; server-v* tags build+push the image to the Gitea registry and attach linux amd64/arm64 binaries + SHA256SUMS to a release — the artifact self-update consumes.
