The on-disk format was detected by sniffing the first byte for `[` or `{`.
Encrypted blobs begin with a random 12-byte nonce, so roughly 1 in 128
saves produced a valid encrypted file whose first byte was 0x5B or 0x7B;
those were misread as plaintext JSON, failed `String::from_utf8`, and the
store became permanently unreadable. This was surfacing as a flaky
`test_list_credentials_no_filter`, but it is a real data-loss bug: a node
whose ciphertext happened to start with one of those bytes could not load
its credentials.
Writes now carry a fixed `ARCHYCRED1` marker, which cannot collide with a
random nonce, so detection of the current format is exact.
Legacy unmarked files are detected by SUCCESSFUL AEAD DECRYPTION rather
than by another byte sniff. A verifying Poly1305 tag under the node key is
a cryptographic discriminator (~2^-128 false-positive rate), strictly
stronger than any structural guess — which is why the deferred item's
suggested "keep the first-byte sniff as the legacy fallback" was not the
shape adopted. Plaintext JSON remains the last resort, and is still
reachable on a node that has no node key at all.
An undecodable file now errors instead of returning an empty store, so a
transiently unreadable file is never silently replaced by an empty one
that the next save would commit to disk (CLAUDE.md: migrations never
destroy data). Legacy files upgrade on write, never on read.
Tests drive the collision deterministically via an explicit nonce rather
than waiting on the 1-in-128 draw, and cover all three on-disk
populations, the read-path-does-not-rewrite guarantee, and tamper
rejection. 28 passed, 0 failed.
Closes the 10-01 deferred item.

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.
