"""v35 -- the two gates are the discrete<->continuous BOUNDARY, not missing formulas.

The user's intuition: TFPT is built on extremely simple foundations, so the two
remaining gates should not be super-complex special cases.  The honest, simple
resolution: they are not interior compiler problems at all -- they are exactly
where the discrete compiler HANDS OFF to continuous physics.

QUARK GATE (U_wall) -- evidence: the "cleanness" of the quark cross-ratios tracks
the GENERATION / QCD-sensitivity:
  * t/b (gen 3, heaviest, least scheme-sensitive): clean, 3/26 = N_fam/(2 Delta_Q),
    error ~3e-5 -- no competing simple rational that close.
  * c/s (gen 2): ambiguous -- 21/29 AND 34/47 both fit to ~5e-4.
  * u/d (gen 1, lightest, most scheme-sensitive): ambiguous -- 8/17 AND 55/117
    both fit to ~5e-4.  So the "11" in 55/117 is NOT forced; 8/17 fits equally.
This is exactly the FLAG caveat: light-quark masses are scheme/QCD-sensitive, so
their c's are NOT clean compiler rationals -- they are QCD-dressed.  The compiler
delivers the CLEAN skeleton (integer ladder K, word-lengths, the algebraic
splitting type, and the cleanest ratio t/b); the continuous light-quark amplitudes
are standard QCD, not a missing compiler datum.

GRAVITY GATE (G_metric) -- same shape: the compiler delivers the clean discrete
skeleton (R+R^2, scalaron M=c3^{7/2}Mbar, n_s,r,A_s); the full metric measure is
the continuous (GR/QFT) completion, not a compiler special case.

So: not "two complex special cases we are missing", but the EXPECTED boundary of
a discrete compiler.  No formula is being overlooked; the gates are the handoff.
