# Request ppdata: signer (tx.from) backfill for v3hist first-600s swaps, 12 Sep - 5 Oct
Why: /opt/sw/v3hist.db swaps.signer is empty for 5.98M of 9.38M rows (12 Sep - 5 Oct, ~93k on 6 Oct). Every wallet lens (prior-whale buyer, veteran share, smart-money) can only use 6-15 Oct = n~250 band pools; a clean time split needs ~560.
What: for pools born 12 Sep - 5 Oct, fill signer (and recipient if cheap) for swaps with t <= first_trade_t+600s (about 3-4% of rows). Free RPC, tx.from per distinct tx hash. Same table, same columns.
Test I run on arrival: v3 mc5 band (cap@+300s 150k-1M): skip when any first-300s buyer previously made a single buy >=1 ETH (v3live 6-15 Oct: 40 pools, stopped 72% vs 45%, mean 0.9 vs 1.5; second half only 1.07 vs 1.30). Kill if the held-out half shows no gap >=0.15 in mean exit multiple.
