# Request: threshold-cross timestamps in live_paths (analyst1, 17 Oct)
What: /opt/ppcopy/live_paths.db table pools: column `crossed` lists thresholds only. Add table `cross_t(pool text, thr int, t real)` = first unix time the pool cap crossed each of 100k,300k,1M,3M,5M,10M,20M (same 14.1k pools, 3 wk, back to 5 Oct).
Why: every regime/concurrency/hot-meta lens is unusable as-of without it (using eventual max_cap = look-ahead). With it: (1) "runners live right now" count at each birth -> P(1M) by concurrency, size pause rule; (2) time-to-1M curve -> entry-delay value; (3) runner hand-off (a runner dies, next one is born within X min).
Format: sqlite table in the same file (or sidecar live_paths_cross.db), refreshed with the radar save.
Test: concurrency-at-birth quintiles vs P(1M) on small-born v3/native/usdg pools, halves split; pass if lift >=1.5x in both halves.
