Groundwork for the .126 LoRa settings panel (operator top priority):
- --airtime-limit-short/--airtime-limit-long (percent duty-cycle locks,
e.g. EU868 25/10) written into the RNode interface config when set;
default None writes nothing — identical to older daemons.
- New socket RPC {"cmd":"radio_state"} returns the live RNodeInterface
state: requested config values AND the radio-confirmed r_* values
(r_frequency/r_bandwidth/r_txpower/r_sf/r_cr/r_st_alock/r_lt_alock,
online, port, airtime utilisation). The r_* values are what the RADIO
reported after detect/configure — the settings panel's proof that the
device is actually using what was applied.

reticulum-daemon
Host-supervised Reticulum (RNS) + LXMF bridge for Archipelago's Mesh tab. This is the Python side of the Reticulum transport plan: archipelago spawns one of these per active Reticulum (RNode) radio, it owns the serial port, and the Rust mesh subsystem drives it over a Unix-socket JSON-RPC.
Why a daemon (not the Rust reticulum-rs crate): the canonical Python rns/lxmf
guarantees interop with Sideband / NomadNet / MeshChat, and lets us derive the RNS
identity from the existing Archy key (proven in spike_identity.py).
Layout
archy_rns_identity.py— derive a deterministic RNSIdentityfrom the 32-byte Archy Ed25519 seed (identity_dir/node_key) via domain-separated HKDF. The node's LXMF destination hash is a stable function of the Archy identity.spike_identity.py— Phase-0 gate #1 (no radio): proves that determinism.reticulum_daemon.py— the daemon: RNS bring-up, LXMF router, announce handler, and the Unix-socket RPC. See its module docstring for the wire protocol.requirements.txt— pinnedrns==1.3.5,lxmf==1.0.1(validated on Python 3.13).
Dev setup
python3 -m venv .venv
.venv/bin/pip install -r requirements.txt
Run the spike / smoke tests (no hardware)
.venv/bin/python spike_identity.py # gate #1: identity determinism
.venv/bin/python reticulum_daemon.py --check \
--identity-key /path/to/node_key # print this node's dest hash
.venv/bin/python reticulum_daemon.py --selftest \
--identity-key /path/to/node_key # bring up RNS+LXMF, no radio
Run against a real RNode (Phase-0 hardware gate, on .116 / .228)
.venv/bin/python reticulum_daemon.py \
--identity-key /var/lib/archipelago/identity/node_key \
--serial-port /dev/reticulum-radio \
--socket /run/archy/reticulum.sock \
--display-name "archy-228"
Then verify a two-node LXMF DM over LoRa and interop with a stock Sideband/MeshChat client (Phase-0 gates #2 and #3).
Packaging (Phase 1)
Ship as a PyInstaller single binary in the OTA next to /usr/local/bin/archipelago
(no provision-time pip install). archipelago supervises it: start on RNode detect,
kill on unplug/disable. The RPC socket and RNS config dir are archipelago-owned, 0600.
./build.sh # → dist/archy-reticulum-daemon (~16M, fully standalone)
-d noarchive is required, not optional — see the comment in build.sh: RNS computes
RNS.Interfaces.__all__ via a glob() against its own __file__ directory at import
time, which only works when PyInstaller keeps modules as loose files instead of zipping
them into the binary.
Status
Phase-0 gate #1 (identity determinism) passes, verified in both the dev venv and the
packaged binary (same dest hash). The signed-identity announce (ARCHY:2:{ed}:{x25519} in
_announce_app_data, via --archy-ed-pubkey-hex/--archy-x25519-pubkey-hex) is wired and
the Rust side (reticulum.rs) already passes the node's real keys through. Packaging is
done and verified standalone. What's left is entirely hardware-dependent: the live LoRa
message path (Phase-0 gates #2/#3) needs a real RNode-flashed board.
