With Bitcoin Core's wallet deleted, LND's PSBT round trip is the only external-signer path Archipelago has, and D-09's key-origin protection moves from Core descriptors (of which none remain) to the PSBT itself. Adds `psbt_key_origin_report(&str) -> Result<PsbtKeyOriginReport>` to lnd/wallet.rs, reporting `input_count`, `inputs_with_key_origin` and `all_inputs_have_key_origin`. An input counts as carrying key origin when either its `bip32_derivation` or `tap_key_origins` map is non-empty. A PSBT with zero inputs reports false rather than vacuous truth. Parsed with the already-present `bitcoin` and `base64` crates; no dependency added. `lnd.create-psbt` gains an additive `key_origin` object on its response and a `tracing::warn!` with the counts when key origin is missing, because that is the exact condition under which a hardware signer refuses the PSBT. Computed best-effort: a decode failure degrades to `null`, never to an error, so a user's send cannot fail because an inspection helper could not parse something. `handle_lnd_finalize_psbt` and `handle_lnd_create_raw_tx` (which deliberately auto-signs with LND's hot keys) are untouched. Three tests, with fixtures built programmatically from the `bitcoin` crate rather than pasted as opaque base64: with-derivations, without-derivations, and malformed-is-an-error-not-a-panic. KEY-03-SIGNING-POSTURE.md gains an honest per-step coverage map of the fund -> export -> sign offline -> import -> finalize -> broadcast round trip. Of six steps, only the new inspection has automated coverage; steps 1, 4, 5 and 6 have none, and there is no air-gap transport (no animated QR, no .psbt file exchange) — export/import is copy-paste of base64. Untested paths are named as untested. Records the verdict that decides whether any of this is an air gap: on a default node an external signer CANNOT meaningfully sign a PSBT from `lnd.create-psbt`, because LND holds the keys for every input it selects. Evidence: the PSBT is funded from LND's own wallet; `ensure_wallet_initialized` creates a full key-holding wallet via /v1/initwallet; the generated lnd.conf carries no `remotesigner.*` block; and a search of apps/, scripts/, core/archipelago/src and image-recipe/ for remotesigner/createwatchonly/ nochainbackend returns zero matches. No fleet node is provisioned watch-only. What ships is PSBT transport, not air-gapped custody — the gap is provisioning, not plumbing. Adds the standing honesty statement in its own subsection: Lightning channel, revocation and HTLC keys are NOT air-gappable at all. They must sign in real time to answer counterparty commitments; remote signing relocates them to a hardened host, it does not cool them. Also adds a status banner to PSBT-SIGNING-ARCHITECTURE.md recording that its Phase 1 was superseded by deletion rather than delivered, so §0's "single highest-value change" and §2.1's invariant now read against a code path that no longer exists. Banner only; §5.4's honesty table is byte-identical. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
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.
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.rsis 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:
- Architecture
- Developer Guide
- App Developer Guide
- App Manifest Spec
- Nostr Git Source Hosting Plan
- Operations Runbook
- Troubleshooting
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.
