Port upstream sgl-project/sglang #24416 (staging-free). Our transfer metrics were computed from the full prompt length, so total_mb / speed_gb_s were systematically over-reported on every prefix-cache hit and every CP shared-KV per-rank page filter. Now each sender accumulates the actually-sent KV/state indices and reports bytes = sent_pages * per-page item bytes via a new KVTransferMetric returned by get_transfer_metric(); prefill consumes that instead of estimating from len(origin_input_ids), and skips fake-bootstrap and dummy-CP-rank senders (which transfer nothing). Also route convert_to_duration() phase deltas through duration_between(), which returns 0 when a phase timestamp is uninitialized, fixing nonsensical negative durations in the time-stats log. Unit-tested (test_kv_transfer_metrics.py, 10 cases) in the CUDA-13 container. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
