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).

mDNS-style LAN discovery (iroh MdnsDiscovery, discovery flag, default
on) feeds a presence tracker; trusted peers that appear trigger fetches
of every incomplete pin, and Pin itself now fetches from present
trusted peers. Serving is our own ProtocolHandler: trusted NodeIds get
the full store, everyone else a filtered view limited to open_lan pins
and ticket-exported hashes (plus hashseq children) that answers "not
found" for the rest. Ticket export records standing serve-consent for
that hash; trust changes take effect on new connections. ShapedStore
implements the full iroh-blobs Store trait to charge provider reads to
an upload token bucket and downloader writes to a download bucket;
upload cap 0 closes incoming connections at accept. Subscribe now
streams transfer_progress both ways, peer_joined, and pin_complete.
Tests: forged-ticket trust gating (denied untrusted, served after
trust), 256 KiB/s upload cap enforced by wall clock, event stream
during a transfer, and real-mdns auto-sync between two daemons
(skips where multicast is unavailable).
Dependencies: n0-future, async-channel, futures-lite, bytes — all
already in the tree via iroh; needed directly to name types in
iroh-blobs trait signatures and channels. iroh feature
discovery-local-network for MdnsDiscovery.

The daemon binds an iroh endpoint (ed25519 identity at secret.key,
0600), serves its store via Blobs/Router on the standard ALPN, and
fetches with the iroh-blobs Downloader rather than the rpc client to
keep quic-rpc out of the tree. Relay is disabled unless wan_upload is
set: LAN-only, zero WAN upload by default. TicketImport pins first
(the pin is the GC root protecting in-flight data), registers the
ticket's NodeAddr with the endpoint (the downloader dials by NodeId
alone), then fetches in the background; completion emits pin_complete.
Tests: two-daemon localhost transfers (blob + directory collection,
byte-identical), and kill -9 mid-transfer followed by restart on the
same store resuming to completion.
Dependencies: iroh 0.35 (endpoint/router, pairs with iroh-blobs 0.35),
rand 0.8 (secret key generation, same version iroh uses).

iroh-blobs 0.35 fs store under <store_dir>/blobs. Add imports files or
whole directory trees (as Collections, deterministic order), Materialize
exports them with a real FICLONE reflink attempt and streaming-copy
fallback, Gc is an explicit mark-and-sweep rooted at the pins. Pins,
trusted peers and hash formats persist in meta.json (atomic writes).
Store reads run on a LocalPool because iroh-blobs entry readers are not
Send. Integration tests drive the real daemon binary: directory round
trip byte-identical, gc keeps pinned/drops unpinned, reflink verified on
the repo's own filesystem (XFS), plus a 32-case proptest round trip.
Dependencies: iroh-blobs =0.35.0 (the store itself; pinned per spec),
iroh-io (AsyncSliceReader traits to read store entries), reflink-copy
(FICLONE with copy fallback, per spec), proptest (dev-only, round-trip
property test).

Three-crate workspace per SPECS.md. varde-proto defines the full JSON
Lines protocol (requests, envelopes, structured errors, events) with
string-typed hashes so the crate carries no iroh dependency. The daemon
binds its unix socket, loads config with flags > env > file > defaults
precedence, and answers status/list; everything else returns a
structured "unimplemented" error. varde-ctl maps subcommands 1:1 onto
requests and round-trips status against a real daemon in the tests.
Dependencies: serde/serde_json (wire format), tokio (async runtime and
unix sockets), tracing/tracing-subscriber (structured logging), toml
(config file), anyhow (binary-edge errors), thiserror (reserved for
library errors), clap (ctl flag parsing, per spec), tempfile (dev-only,
ephemeral test dirs).
