Calculation record

Exact finite-harmonic compatibility checks for one response per depth.

The source vectors are algebraic controls, not physical measurements. The
calculation asks whether one depth-wide bias can make every maintained mode
orthogonal to its eliminated positive response on an explicit finite harmonic
control space. The infinite completion is checked by the companion script.

Research context

  • Finite biased support and the mode-selection boundary

    One positive response bias can satisfy the field-orthogonality equations for a finite selected set at each depth, but the same bias fails the next unselected mode and therefore requires a derived mode-selection law.
