1000 idle + 1000 motion synthetic-but-parameter-matched CSI
frames live under tests/fixtures/replay_*.jsonl; the cargo test
`replay_2000_packets_f1_above_threshold` replays each through
amp_presence_override and asserts F1 ≥ 0.85.
Fixtures generated by scripts/generate-replay-fixtures.py (seeded
42/43). Parameters mirror data/baseline.json: per-node baseline
mean from live recording, idle σ=1.8 % per-frame noise, motion
±40 % envelope at 0.15 Hz (long enough to swing the classifier's
4.5 s rolling CV) plus 5 % per-frame noise.
Current run: F1 = 1.000 (tp=822, fp=0, tn=822, fn=0; 178 warmup
frames per fixture excluded). 0.85 threshold leaves headroom for
classifier evolution.
Test resets per-node history + per-sub baseline between fixtures
so each run is hermetic; keeps the per-node baseline-CV so the
ADR-103 universal-threshold path stays exercised.
