Dorian 22f8129b52 feat(companion): backup & restore + NIP-46 remote signer — 0.5.28 (#128, #139)
Companion 0.5.28 (versionCode 48), the companion-agent queue items:

#128 Backup & Restore — the phone side of losing your phone or wiping it
to cross a border. Hub card → SAF export/import of an encrypted .json:
everything the app holds (servers+passwords, FIPS identity/peers, signer
key) sealed in the node's ADR-005 envelope (Argon2id + ChaCha20-Poly1305,
native backup.rs — same blob layout as the node's, node-shaped envelopes
decrypt too). Restore is merge-only: servers upsert npub-first, identity
and signer key adopt only when absent, peers union by npub. No cloud, no
telemetry — the file goes wherever the user saves it.

#139 Remote Signer — the phone IS the NIP-46 bunker. Generate/import a
nostr key, scan a nostrconnect:// QR (in-app scanner or deep link), and
approve/deny each sign_event request from a legible card (kind label,
content, tags, time) — nothing signs without a human. Wire-faithful to
rust-nostr's reference bunker (connect-carrying-secret handshake, NIP-44
v2 transport with NIP-04 receive fallback, kind-24133 responses);
get_public_key/describe/ping handled, everything else 'not authorized'.
Session state in BunkerManager, UI in SignerScreen, hub card wired.

Plus NativeCore (JNI object for the new native surface), FipsPreferences
peers-merge for restore, nostrconnect:// intent filter, and the release
docs (companion-backup-restore.md, companion-nip46-remote-signer.md).

Also Android/tools/nip46-test-client.py: a pure-Python NIP-46 client that
plays the node's login role (QR, handshake, get_public_key, sign_event)
and verifies the phone's signature with an independent BIP-340 — the
end-to-end test for the feature until node-side lands. Its crypto matches
the official NIP-44 + BIP-340 vectors byte-for-byte, the same vectors the
Rust core passes, so the two interop by construction.

Built + smoke: assembleDebug v0.5.28/vc48, same signing cert as the
served 0.5.27 (d622e07e…644d) so it updates in place.

Archipelago

Self-sovereign Bitcoin node OS and manifest-driven app platform.

Archipelago is a bootable personal server OS for Bitcoin infrastructure, self-hosted apps, mesh communication, decentralized identity, and federation. Apps are packaged as declarative manifest.yml files and run as rootless Podman containers managed by the Rust backend.

Debian 13 License Rust Vue.js Version

What is here

  • core/ - Rust workspace: backend API, container runtime, security, OpenWrt helpers, and performance/resource management.
  • neode-ui/ - Vue 3 + TypeScript frontend.
  • apps/ - app manifests and custom app container sources.
  • docker/ - supporting container build contexts for UI companion surfaces.
  • image-recipe/ - bootable image/ISO build inputs.
  • Android/ - Android companion app.
  • scripts/ - development, release, deployment, and validation tooling.
  • docs/ - architecture, app packaging, operations, API, and roadmap docs.

Platform model

Archipelago is built as a developer-ready app platform, not a fixed appliance:

  • Apps are declared in apps/<app-id>/manifest.yml.
  • The Rust parser in core/container/src/manifest.rs is the canonical schema.
  • The orchestrator compiles manifests to rootless Podman/Quadlet runtime state.
  • App data lives under /var/lib/archipelago/<app-id>/.
  • Secrets are generated or read from /var/lib/archipelago/secrets/ and injected through Podman secrets rather than static environment values.
  • Release and app catalogs are signed and verified against a pinned trust anchor.

Start with:

Quick start

Frontend

cd neode-ui
npm install
npm start

The dev UI runs at http://localhost:8100 with a mock backend on :5959.

Backend

cd core
cargo build
cargo test --all-features

Linux is the supported backend runtime and release-build target. macOS is fine for frontend work and many Rust compile/test loops, but host integration tests that touch Podman, systemd, networking, or image build paths require Linux.

App manifests

./scripts/validate-app-manifest.sh apps/filebrowser/manifest.yml
python3 scripts/generate-app-catalog.py
python3 scripts/check-app-catalog-drift.py --release --strict

scripts/generate-app-catalog.py requires Python with PyYAML installed.
