Some checks are pending
offline / test (push) Waiting to run
Central fleet.json sets min/max copies. Tree-node keepFloor respawns until three healthy unpaused replicas remain. CLI and loopback UI pause, resume, stop, and restart instances that fail health checks.

# Fleet: replica floors, monitor, pause, restart
|
|
|
|
Runtime copies of middleware workers, WORM archives, and **tree nodes** are declared in `packages/verae-fleet/fleet.json` (how many) and `packages/verae-fleet/services/*.json` (how each one runs).

operator --HTTP 127.0.0.1:3850--> fleet control

unhealthy → restart v
|
|
replicas on loopback health ports
|
|
```
|
|
|
|
- **list** — `node src/cli.js list`
|
|
- **monitor** — `serve` probes `/health` and reconciles
|
|
- **restart** — crash or 503 → same instance id respawned
|
|
- **pause / off** — pause does not count toward `min`; keepFloor starts another tree-node. `stop` on a service disables it.
|
|
- **tree-node floor** — `fleet.json` `tree-node.min` (default 3). Do not drop this without changing the spec; bulk-summary leaf queries need several bloom-filtered nodes.
