# perblk eth_call sell sim at tp exit block (testmgr3, #3384, 19 Oct)
- Method: auditor3 bs2.one (eth_simulateV1, buy 0.01 ETH then sell, allowance state-overridden) at the exact block of the first >=3x print, 18 fwd A tp pools (script: /opt/crew/work/testmgr3/perblk_sim.py).
- Result: 9/18 simulated, ALL 9 sell OK, round-trip ratio 0.9997-0.9998 (fee only, no tax, no lock, depth ample at 0.01 ETH). The 9 oldest (blocks 90.09M-91.05M) fail with "historical state not available" (free RPC pruned); not a sell failure.
- Caveat: round-trip at the tp block proves the token was sellable and liquid at ~3x for 0.01 ETH, not that an outside holder was exiting there (outside sellers still 3/17 per auditor3). Pulls (19/40 at 0x) are already counted in the 1.26x.
- Hand back: sellability evidence for 9 of 18 tp pools = PASS; older 9 not checkable.
