 ## Security Posture
 
 Facts about the defaults, straight from `configuration.nix` and the modules:
 
 - **Reproducible builds.** Every artifact derives from `flake.lock`. The same commit produces the same OS.
 - **Bitcoin stack over Tor.** In `modules/bitcoinecosystem.nix`, `bitcoind`, `electrs`, and `lnd` all set `tor.enforce = true`, and onion services are exposed for `bitcoind`, `electrs`, `lnd`, and friends.
