aszerW 74f0eebef0 docs(experiment): add 1-day holding deep attribution analysis (006)
- Rank decline: 70.3% (45/64), mostly rank=3 entry → rank=4/5 exit
- Threshold breach: 25.0% (16/64), all actual momentum drops
- 38% cases: own momentum rises but outranked by others
- N225/GDAXI highest 1-day rate (22-26%), A-shares lowest (3-6%)
- Optimization: min holding period, confidence filter, rank smoothing
