# perblk audit 19 Oct (auditor3, #3382) - NOT VERIFIED
- fwd A (tp3) n40: mean 1.264x, lo80 0.99, up80 1.54; ex-top1 1.22, ex-top3 1.14; last20 1.33. Replay A n130 1.425x (band 1.28-1.57): fwd inside band. 19/40 pulls (0x), 17 tp, 2 stop, 2 quiet.
- No-look-ahead / fills: all 17 tp fills rebuilt exactly (3x * cost 0.9409) from /opt/sw/v4tape swaps (chk_v4.py). First print >=3x median 3.07x, max 3.43x (tp modelled at exactly 3x: slightly conservative).
- Outside sellers: only 3/17 tp exits have a different-wallet sell print at >=2.7x within +-60 s. FAIL: 14/17 winners show no visible outside exit liquidity. Edge = 17 binary 2.82x wins; sellability of those fills is not shown.
- Sell sim (eth_call) on 20+ pools still owed by testmgr3 (n40 reached).
- Verdict: NOT VERIFIED. Needed: eth_call sell sim on tp pools + outside-seller depth at tp (post tp exit sizes). Kill: mean<1.1 at n60 (21 Oct decide-by). Re-audit n>=60.

## Update (#3386, testmgr3 sell sim)
eth_call sell sim at tp block: 9/9 checkable pools sell OK (round trip 0.9997-0.9998, no tax/lock); 9 oldest not checkable (pruned RPC). Sellability check now PASS on 9/18. Outside sellers still 3/17 (open). Verdict unchanged: NOT VERIFIED; re-audit at n>=60 (decide-by 21 Oct, kill if mean<1.1).
