When use_quadlet_backends flips from off → on, existing fleet boxes have backend containers parented under archipelago.service's cgroup (the bad shape that triggers FM3 cascade SIGKILL on every archipelago restart). ensure_running now notices and corrects this: * If there's already a `<name>.container` unit on disk → no-op (subsequent reconcile ticks take this fast path). * Else if a podman container with that name exists → it's a pre-3.3 artifact. Stop+remove it (volumes survive — bind mounts are not touched by `podman rm`), then write the Quadlet unit, daemon-reload, and start the new managed service. * Else → fall through to install_fresh, which already routes through install_via_quadlet when the flag is on. The migration is idempotent and self-healing: if a fleet box is half-migrated (unit on disk but no service active, or service active but stale unit), the next reconcile tick converges. Bitcoin chain data, lnd wallet state, and electrumx index all live on host bind mounts and are unaffected by the container-record swap. Volume safety audited per backend in `uses_orchestrator_install_flow` allowlist — every entry mounts its data dir as a host bind mount. Default still off. To migrate a node: /etc/archipelago/config.toml: use_quadlet_backends = true followed by `systemctl restart archipelago` — the next reconcile tick walks every managed app and migrates each in turn. Tests: 624 passing, 0 cargo warnings. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Container subsystem testing — scorecard and roadmap
The bar (verbatim from the v1.7.52 owner):
"best performant, minimal code, tested containers possible in the world. No bloated code, no problems installing a single one, no problems uninstalling, every one needs to be tested 20+ times in every state before we make another update, not a single container failure outside of hardware or internet failure is allowed."
This document is the live tracker for whether we're meeting that bar. Every PR that touches the container subsystem updates the scoreboard below. If you can't honestly tick the box, the change isn't ready.
Test layers
| Layer | What it asserts | Toolchain | Latency / iteration |
|---|---|---|---|
| L0 — Rust unit | Pure-function behaviour (manifest parsing, secret resolution, structural invariants) | cargo test --workspace --bins |
~5s |
| L1 — RPC API | The JSON-RPC API responds correctly per app (container-list, package.{install,start,stop,restart,uninstall}, bitcoin.getinfo, etc.) |
bats + lib/rpc.bash | ~30s per suite |
| L2 — UI surface | The URLs a user actually clicks (dashboard, /app/<id>/, direct-port iframes) return 200 with non-empty bodies |
bats + lib/ui-probes.bash | ~10s per suite |
| L3 — Lifecycle survival | Containers survive operational events (archipelago restart, host reboot, kill -9 mid-install, OOM) | bats (gated) | ~60s per scenario |
| L4 — Browser journey | Real DOM-level user flow (login → install → wait → click → use) | playwright (TBD) | ~30-120s per journey |
| L5 — Chaos / failure-path | Failure modes recover gracefully (corrupt config, deleted bolt DB, network partition) | bats (chaos-gated) | ~120s per scenario |
| L6 — Performance | Cold install latency, reconcile-tick cost, podman call count per lifecycle event | timed bats + Prometheus (TBD) | ~60s per benchmark |
Release gate: L0+L1+L2+L3 green × 20 iterations on .228 AND .198. L4+L5+L6 are quality gates we add as they mature; not blocking the v1.7.52 tag.

Today: -270 LoC committed. Outstanding deletes possible: ~1,616 LoC (if Phase 3 ships fully + dev_mode resolved).
Net target for v1.7.52: container subsystem ≈ half of today's LoC.
Performance KPIs (TBD — measure first, then target)
We don't have a performance harness yet. Add as L6 lands:
| KPI | Today | Target | Notes |
|---|---|---|---|
cold install: bitcoin-knots manifest → running healthcheck |
unknown | < 30s once image is local | excludes the ~1GB image pull |
| cold install: lnd | unknown | < 60s once image is local | wallet unlock dominates |
| reconcile-tick wall time (no-op pass over all installed apps) | unknown | < 250ms | the current orchestrator does many podman inspect calls |
| podman shell-outs per package.install (orchestrator path) | 7-10 | 1-2 (Quadlet) | post-Phase-3 |
| daemon startup (boot → port 5678 listening) | unknown | < 5s | reconcile is async after this |
Release gates
v1.7.52 ships only when ALL of:
- ☐ Bitcoin-stops fix verified live on a fresh node (tests/lifecycle/bats/bitcoin-knots.bats fully ● after a cold install)
- ☐
tests/lifecycle/run-20x.shreturns 0 against .228 (full suite, ARCHY_ALLOW_DESTRUCTIVE=1) - ☐
tests/lifecycle/run-20x.shreturns 0 against .198 (same) - ☐ The L3
backend-survives-archipelago-restartsuite passes (= Phase 3 Quadlet shipped for backends) - ☐ Cargo: 0 warnings, 0 unused, all tests green (sustained ✓ since
1c0df95f) - ☐ LoC: at least one of {Phase 3 Quadlet, dev_mode resolution} merged
- ☐ Layman-readable changelog (per
feedback_changelog_layman.md) - ☐ Tag pushed to origin + gitea-local + gitea-vps2 (per
feedback_ship_ritual.md)
How to update this document
When you land a change that materially moves any cell of the matrix or any LoC row, update this file in the same commit. Reviewers checking the PR can read the diff to TESTING.md as the answer to "what did this commit improve?". Without the update, the change is half-shipped.
