scripts/slice_engine_state.py filters a shared engine_*.jsonl by a [t_start_unix, t_end_unix] window. Needed because the patched scheduler appends to one file per engine across the whole sweep; per-policy analysis requires the per-policy slice. scripts/b3_analyze.sh drives the slice + joined_analysis loop for every policy directory in a completed sweep, then aggregates one row per policy (latency percentiles, APC, interference_index, hotspot_index, reuse fractions, failure-cause counts) into b3_policy_comparison.json.
