Live conditions are analysed at their current run length; the number and its history update as the streak extends. Dormant conditions (the ones still short of their minimum length) show what happened the last times they did reach it. Rarity, for a live streak, is the share of this condition's past qualifying runs that never got this long, near 0% for a fresh streak, climbing as it extends. Forward-return columns summarise the analog set: prior runs that reached the same length, de-duplicated so one long streak counts once, tracked over the next year (samples shrink at the longer horizons as recent analogs run out of runway). Regenerate with node scripts/oddstats-detect.js --dump. Food for thought, not a signal.
