scripts/b2_interference.py is the controlled microbench. It runs two coroutines against the open proxy bypass (direct vLLM endpoints): - decode_load: continuous short-prompt requests at fixed QPS into a designated decode instance, to keep it decode-saturated. - prefill_injections: N large one-token requests at fixed interval, pointed at either the same instance (same-worker variant) or a paired one (different-worker control). Each cell (variant × prefill_size) gets its own metrics.jsonl plus a run_window.json containing t_start_unix/t_end_unix. The shared engine_*.jsonl from the scheduler patch is sliced by that window in the aggregator. analysis/characterization/b2_sweep_analysis.py walks the cell tree, slices the per-worker step log by each cell's window, runs the A5 interference_index() against the slice, and emits a single b2_sweep_summary.json with one row per cell. This is what feeds the "interference vs uncached prefill size" figure. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
