"""Settling the context score with nine instruments instead of four.

On the honest engine the Wyckoff context slope landed at +0.0239 R/trace, t +1.37, sign held
in 6 of 8 cells - too weak to trade, too consistent to dismiss. `sqxbars.py` has since made
five more instruments readable, sharing no data path with the original four: FTSE100, UK100,
WTI (two independent feeds) and USDCAD.

The test is unchanged and was fixed before any of this ran: the ORIGINAL LPS configuration
(market entry at the next bar's open, stop at the retest extreme, 2R target), scored by the
five traces of book 2 2.3 / 7.1, with the single pre-specified prediction that expR rises
monotonically with the number of agreeing traces. Nothing is tuned per instrument.

WHAT WOULD SETTLE IT EITHER WAY
-------------------------------
  real    the pooled slope holds near +0.024 with t comfortably past 2, and the new
          instruments - which had no hand in choosing anything - carry their share of it
  nothing the slope drifts toward zero as power rises, and the new instruments split evenly

The second is what a small sample of noisy cells looks like when it is finally given enough
data to speak. The five new instruments are the honest out-of-sample here: every parameter in
this test was set on the original four.

Bases on the breadth instruments use a SYNTHESISED spread and are approximate; the slope is
not, because cost is nearly uncorrelated with the context score (measured: +0.0008 R/trace).
