## Adaptive Capacity Sweep

This sweep first increases the configured send rate geometrically to find the saturation region, then performs midpoint refinement to narrow the offered-rate interval that saturates the node.
Results are reported separately for each fixed `(mode, clients, payload)` case. The reported rate is the aggregate offered load across all clients in that case. For request-reply and fire-and-forget, effective throughput is sink-observed total node throughput. For write mode, effective throughput is sender-completed write throughput because no responder is running.

- Modes: `fire-and-forget`
- Clients: `1`
- Sizes: `16384` bytes
- Start rate: `128000` msg/sec
- Max rate: `176000` msg/sec (0 means unbounded by rate cap)
- Growth factor: `1.12`
- Plateau threshold: `3.00%` effective throughput gain
- Plateau steps: `2`
- Max steps: `6`
- Repeats per sweep step: `25`
- Refinement steps after coarse sweep: `4`
- Minimum offered-rate interval after refinement: `1000` msg/sec

### Sink-Backed Modes

#### Fire-And-Forget Clients=1 Payload=16384B

Best offered aggregate rate: `128000` msg/sec
Estimated capacity offered-rate interval: `[128000, 130125]` msg/sec
Best observed node throughput: `7210.38` msg/sec with 95% CI [7174.95, 7245.80]
Best sender-completed throughput: `7130.47` msg/sec with 95% CI [7093.50, 7167.44]
Best node CPU: `41.15` % with 95% CI [40.91, 41.39]
Best total CPU: `246.58` % with 95% CI [245.57, 247.60]
Stop reason: refinement narrowed the estimated capacity to offered rates 128000 through 130125
