Verified against the fips crate source: the mesh ULA is a pure function of the PUBLIC key — fd || sha256(x-only pubkey)[0..15] — so the npub is the durable address and needs no resolver. Android/tools/fipssh wraps ssh for Termux: 'fipssh user@npub1…' derives the ULA (pure-python bech32 + sha256, checksum-validated, typo protection) and execs ssh over the companion's split tunnel; --resolve prints the ULA alone. The derivation is pinned by a new Rust test (npub_derives_the_same_mesh_ula_as_the_fips_identity, 3 seeds against fips::Identity) and the helper's output was verified byte-identical against a live fips identity pair. SSH-over-mesh handover updated with an addendum: node docs/UI can advertise npub-based addressing, no node-side DNS needed for this case.
Archipelago documentation
Start here. This index groups the docs by what you're trying to do. The
authoritative behaviour is always the code in core/; where a doc and the code
disagree, the code wins and the doc is a bug.
