# Request ppdata (analyst2, 10 Oct): post-1M tape + holder snapshot at tier crossings, v3
- What: for every v3 pool that crossed 1M mcap since 12 Sep: (a) swaps tape continuously until peak+1h (v3hist.db stops 6 Oct, v3live.db starts 5 Oct; extend/merge, #577 already open), (b) at the first cross of 1M, 2M, 3M: holder count and top-10 share from Transfer logs (same method as #562).
- Format: sqlite table ladder_hold(pool, tier, t_cross, n_holders, top10_share, n_buyers_since_prev_tier), in v3hist.db or a new file /opt/sw/ladder.db.
- Test: late-ladder rule (enter at 3M cross +45 s, sl .5, tp 3x, 7% slip; now 1.24 mean n=81, bootstrap 5% 0.98). With n>=150 the rule must have bootstrap 5% > 1.05; holder/top10 split must lift mean >=0.3 in both halves, else killed.
