- example_iot_load_test: simulates N devices (default 100 across 10
groups: 55 + 9×5) pushing DeploymentState every tick to NATS, no
real podman. Applies one Deployment CR per group, runs for a
bounded duration, verifies each CR's .status.aggregate counters
sum to the target device count.
- iot/scripts/load-test.sh: minimum harness — k3d cluster + NATS via
NatsBasicScore + CRD + operator + load-test binary. No VM, no
agent build.
- operator: connect_with_retry() on startup. The NATS TCP probe that
the smoke scripts do isn't enough to guarantee the protocol
handshake is ready (k3d loadbalancer can accept SYNs before the
pod is serving); the load harness hit this racing against a
freshly-rebuilt operator binary.
- drop unused rand dep from iot-agent-v0 Cargo.toml.
100-device run: 6002 state writes in 60s at a clean 100 writes/s,
all 10 CR aggregates converge to target_devices.len() (e.g.
group-00 → 55 = 45 Running + 9 Failed + 1 Pending).
