Brummel fceba077ab audit(0072): cycle close — mean-reversion candidate refuted; drop ephemera
The EWMA Bollinger-band mean-reversion fade is refuted: no cross-index
generalization (FRA40 leans positive, GER40 negative — two correlated indices
disagreeing in sign), no OOS-significant cell on either index, and its lone
IS-significant cell is consistent with multiple-testing noise (full verdict on
#137). The machinery (--strategy stage1-meanrev, the composed EWMA Bollinger
band, zero new nodes) is permanent and kept; only the per-cycle spec/plan are
dropped per the ephemeral-artifact lifecycle convention.
