### Resilience suite (`just e2e-resilience`)
| Scenario | Disruption | What it verifies |
| ----------------- | ----------------------------------- | -------------------------------------------------------- |
| server stop/start | `systemctl stop/start` in VM | EIO on uncached reads, cached reads survive, watcher resubscribes within 10s |
| network partition | `incus pause/start` (silent drop) | EIO within 10s (tonic 3s timeout × kernel readahead), watcher detects via HTTP/2 keepalive within 30s |
| cache resilience | server stop, all files pre-cached | All reads/writes from cache, no server contact needed |
| long outage | `incus pause` for 15s+ | Watcher detects via keepalive PING, resubscribes within 10s of recovery |
## Fixtures
