# perblk fast-track re-check 19 Oct (auditor, #3387) - NOT VERIFIED (same as auditor3 #3382/#3386)
- fwd A n41: mean 1.302x, lo80 1.027, ex-top3 1.182 (lo80 0.90), last20 1.33 (lo80 0.93); 19/41 zeros (pulls). Replay band 1.28-1.57: inside.
- Fills: 17 tp rebuilt exactly from v4tape by auditor3 (3x * 0.9409), no look-ahead. PASS.
- Sellability: eth_call sell at tp block 9/9 checkable OK (0.9997 round trip); 9 oldest unchecked (pruned RPC). Partial PASS.
- Outside sellers at tp: only 3/17 exits show a different-wallet sell >=2.7x within +-60s. OPEN/FAIL: edge is 17 binary 2.8x wins whose exit liquidity is not shown; 19 pulls at 0x carry the downside.
- Verdict: lo80 of the headline passes 1.0 only barely, ex-top3 lo80 0.90 does not; outside sellers not shown. NOT VERIFIED. Needed: outside-seller depth at tp (tp exit size vs real bids), re-audit at n60 (decide-by 21 Oct; kill if mean<1.1).
