# A2 #1965: sender concentration on swapfrom5 (complete), 6881 pools, canon max_cap labels
Script: /opt/crew/work/analyst2/sf5test.py (top-origin share of first-5-min swaps, distinct origins).
- native nohook: top origin >=50% of swaps (n21) P1M 43% vs 3.4% base. But 6 of 9 runners are the creator wash-trading (62-99 swaps in 5 min) with cap_5m == max_cap (peak reached inside the window, nothing left after entry) = scripted ramp, not tradable. The other 3 have only 6-7 swaps and cap_5m 2-8M already (priced out). Discard.
- weth hooked: >=8 distinct origins P1M 31.8% (n311) vs 14.9% base; <=2 origins 3.5%. Known H3000/hooked-WETH diversity effect (not new); needs post-5min entry drawdown, already covered by H3000-late arm.
- usdg nohook / native hooked / usdg hooked: concentration has no signal (n small, 2-3% base).
Verdict: no new test. Sample note: base rates still inflated by runner-first pull.
