Metered detection polls NetworkManager's Metered property over D-Bus (feature "metered", default on; builds without D-Bus via no-default-features). While metered the daemon closes incoming blob connections and defers every fetch; VARDE_FORCE_METERED=true forces the state as a kill switch and test hook. Endpoint UDP sockets get DSCP CS1 best-effort by matching bound ports to /proc/net/udp inodes (iroh hides its fds). systemd socket activation adopts LISTEN_FDS fd 3, readiness is a hand-rolled sd_notify READY=1 (abstract + path sockets), and standalone binding still works unchanged. dist/ ships hardened system and user units (DynamicUser, ProtectSystem=strict, StateDirectory, RestrictAddressFamilies), a commented config example, scdoc man pages validated with scdoc, and an untested PKGBUILD skeleton. Tests: activation-socket round trip via a real fd-3 handoff, READY=1 received on a NOTIFY_SOCKET, metered daemons neither serve nor fetch. Dependencies: zbus (optional, feature-gated D-Bus client for the NetworkManager metered flag). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
