"""Confluence, not lone patterns.

The user's framing, and the EA's own design: weight-10 models are CONFIRMING states that
must never be acted on alone; a trade needs an event model plus agreement. So this tests
the aggregate, three ways:

  vote>=T   CExpertSignalCustom::Direction() - each module casts its highest-numbered
            matching pattern's weight, signed; the non-zero module votes are AVERAGED;
            trade when |average| >= T. This is literally what the shipped EA does.
  quorum>=K at least K of the 4 modules agree on a direction (any strength).
  event+cfm an ACTIONABLE model (weight > 10) fires, AND at least K confirming models
            (weight == 10) agree with it - the doctrine the weights encode.

Same discipline as test_classic.py: sequential non-overlapping trades, break-even ==
chance by the gambler's-ruin identity, family-wise 5% bar from a sign-flip null.
