# Embedded FIPS mesh node for the Archipelago companion app.
#
# Built for Android via cargo-ndk (see Android/app/build.gradle.kts, task
# buildRustArm64) into app/src/main/jniLibs/arm64-v8a/libarchy_fips_core.so.
# Also builds on the host so `cargo test` covers the non-JNI logic.
#
# `fips` is pinned to the fips-native fork rev that this integration was
# developed against — the fork carries Android support upstream lacks
# (Tun::from_fd for a VpnService-owned fd, cfg(target_os = "android") paths).
# Override with a local checkout when hacking on fips itself:
#   CARGO_NET_OFFLINE=false cargo ndk ... --config 'patch."https://github.com/9qeklajc/fips-native".fips.path="/path/to/fips-native/fips"'
