1837 — The Polar Active-Soft Section Is a Morse–Bott Focal Segment

Correction to the naive weighted picture

Entry 1836 isolated the polar section

1+u⋅n=0.1+u\cdot n=0.

This means that the loop point leaves one focus directly toward the other focus in the same region wall. Along the open focal segment,

∣ℓ−Ce∣+∣ℓ−Cb∣=∣Cb−Ce∣.\boxed{ |\ell-C_e|+|\ell-C_b|=|C_b-C_e|. }

The radial dependence does not merely begin quadratically; it vanishes identically along the segment. The correct object is Morse--Bott.

Transverse normal form

Let s∈(0,R)s\in(0,R) be distance along a focal segment of length RR, and let ρ∈R2\rho\in\mathbb R^2 be transverse. Then

∣ℓ−Ce∣+∣ℓ−Cb∣=R+R2s(R−s)∣ρ∣2+O(∣ρ∣4).|\ell-C_e|+|\ell-C_b| = R+\frac{R}{2s(R-s)}|\rho|^2+O(|\rho|^4).

Thus the owner wall has local form

q1=δ+κ(s)∣ρ∣2+O(∣ρ∣4),κ(s)>0.q_1 = \delta+\kappa(s)|\rho|^2+O(|\rho|^4), \qquad \kappa(s)>0.

If the second region wall cuts the segment transversely,

∂sq2≠0,\partial_s q_2\ne0,

then taking its residue leaves

u d2ρδ+κ∣ρ∣2+⋯,u≠0.u\, \frac{d^2\rho}{\delta+\kappa|\rho|^2+\cdots}, \qquad u\ne0.

The generic polar collision therefore produces an ordinary grade-zero logarithmic line, rather than Entry 1836's generic-direction second-Rees line.

Classification

Both ingredients are already frozen carrier data:

The focal segment and its transverse Morse coefficient arise from their physical distance geometry. No new carrier stratum is required.

Qualifications

This is a conditional local normal form. It does not prove that the dehomogenized physical discriminant reaches the polar section. If it does and ∂sq2=0\partial_s q_2=0, a deeper tangency remains and must be retained as an excess complex rather than normalized away.

Next falsifier

Solve the polar boundary equations on the focal segment. Determine whether the second wall has a real transverse zero, a tangential zero, or no zero for the source-compatible deformations. Only the first two activate the polar coefficient.
