evaluation

Paired native/WASM UDP probe

This fixed, bounded probe is used by the controlled latency experiment. It echoes a 32-hex-character nonce and sequence in 1 KiB UDP datagrams and emits one JSON report. latency sends twelve probes with 400 ms read deadlines; both also sends a 32 KiB burst with a ten-second collection deadline. Timeouts remain missing observations. Invalid echo identities and non-timeout transport errors fail the command.

Build from the repository root:

go build -o latency-native ./examples/debuglets/go/latency/evaluation
make wasm SAMPLE_DIR=examples/debuglets/go/latency/evaluation

Arguments are TARGET NONCE latency|both. The controlled experiment owns the echo target and network conditions; use its lane for reproducible baseline comparisons. The existing parent TCP latency example keeps its own interface.
