Exact 2-adic lifting theorem

FPRD-IC-T20

The full 2-adic gate reduces ten lift rows to Hensel graphs

Exact statement

Let F(v,y)=3aP(v)(2x+3y)+1F(v,y)=3^aP(v)(2^x+3^y)+1. Eleven rows of FPRD-IC-T17 have fixed valuation v2(F)=N0v_2(F)=N_0. In each of the other ten rows, the solutions of F(v,y)≡0(mod2e)F(v,y)\equiv0\pmod{2^e} form a one-dimensional Hensel graph: modulo Le=3⋅2e−2L_e=3\cdot2^{e-2}, there are exactly 2e−112^{e-11} states and projection to the vv-coordinate is bijective.

StatusProved by LTE and complete finite base checks; independently reconstructed
External reviewNo documented external or specialist review of these FPRD results is recorded.

Context

The earlier quotient enforced the valuation selecting x, but equality also forces N to equal the 2-adic valuation of the entire left side. That second gate removes a false two-dimensional freedom.

Proof or evidence

For the ten nonrigid rows, shifting y by the current exponent period changes the next 2-adic digit because v2(3^L-1) is exact. Each v-bit therefore has a unique y-bit lift.

Verification notes

Independent C++ and Python implementations reconstruct every lift through e=22 and verify 2,048 states per row with bijective v-projection.

Limitations

  • The theorem concerns the 21 rows inherited from one normalized positive-type-II quotient.
  • A 2-adic graph alone does not exclude its states; the aligned odd-prime certificate is FPRD-IC-T21.
  • No external review or novelty determination is recorded.

Open work

Reuse the full-side valuation gate before applying odd-prime quotients in the remaining fork orientations.
