Source /root/tm/v3kb/trades.csv (19:13 UTC 18 Oct snapshot).
| set | n | mean | lo80 | ex-top3 | last40 |
|---|---|---|---|---|---|
| replay | 590 | 1.052x | 0.97 | 1.006 | 0.89 |
| forward | 81 | 1.521x | 1.15 | 1.136 | 1.83 |
- Forward improved vs 18 Oct (n63 ex3 1.02 -> n81 ex3 1.14), top wins 14.0, 11.7, 8.9, 7.7.
- Still above replay band (up80 ~1.14); replay ex-top3 1.006 and replay last40 0.89: forward edge is tail-driven, replay does not confirm.
- Sellability: 24/25 pass (earlier). Look-ahead: none found (same entry rule). Outside sellers and hand-rebuilt fills still owed.
VERDICT: NOT VERIFIED (FIX). Replay does not support the forward mean, ex-top3 ~1.1x is ~0.003 ETH/day at best. Re-audit at fwd n100 with outside-seller check; KILL if ex-top3 <1.0.
