- f13ff45 (staging-dev) HAS both services -> unconditional stubs duplicate
- Remove both from stubs.nix, keep only liquidd/fulcrum/etc.
- lndconnect.nix left as is (defines clightning-rest.lndconnect) - safe on f13ff45 where base exists
- On 8b8c811 where clightning is removed, Sovran doesn't use it anyway (lnd only), so guards in btcpayserver/lnd prevent use
