"""v322 -- the Galois CP-lock prediction (v320), SHARPENED: the multiplier is the
deck order, the sub-leading budget is bounded, and the current global-fit tension is
computed -- turning the leading relation into a pre-registered, quantitative kill test.

v320 established the EXACT leading relation delta_PMNS = delta_CKM,lead + pi from the
single hexagonal unit rho = zeta_6 (v316).  This module sharpens it three ways that a
referee would ask for: (a) WHICH of the six hexagonal nodes is selected and WHY (the
multiplier is |mu4|=4, the deck order), (b) HOW BIG the unclosed sub-leading correction
can be (bounded by the quark-analog 3 lambda^2), and (c) WHERE the data sit TODAY (the
NuFIT 6.0 normal-ordering tension) and what future reach makes it decisive.

  [E] 1. DISCRETE LADDER: the leading CP phase can only sit on the six hexagonal nodes
         arg(rho^k) = k*60 deg, k=0..5 ({0,60,120,180,240,300}); delta_CKM,lead = 60 deg
         (node 1) and delta_PMNS,lead = 240 deg (node 4) are two of them.
  [E] 2. MULTIPLIER = DECK ORDER: delta_PMNS,lead = |mu4| * delta_CKM,lead = 4*(pi/3) =
         4pi/3, which equals delta_CKM,lead + pi (rho^4 = -rho) -- the SAME node 4 from two
         readings; the multiplier that selects the node IS the seam clock order |mu4|=4.
  [C] 3. SUB-LEADING BUDGET: delta_CKM,full = pi/3 + 3 lambda^2 (~68.7 deg); the leading
         relation uses pi/3, and the lepton sub-leading is a SEPARATE, currently-open
         holonomy term bounded by ~3 lambda^2 ~ 8.7 deg => prediction band 240 +- ~9 deg.
  [N] 4. CURRENT TENSION: vs NuFIT 6.0 normal ordering (delta_CP = 212 +26/-41 deg) the
         leading 240 deg sits at ~+1.08 sigma; the band's lower edge (~231 deg) at <0.8
         sigma -- comfortably compatible today.
  [X] 5. SHARPENED KILL TEST: the nearest WRONG hexagonal node (180 or 300 deg) is 60 deg
         away, far beyond the ~9 deg sub-leading budget; a DUNE/Hyper-K measurement at the
         projected ~5-15 deg precision discriminates the node cleanly, and any robust
         landing outside 240 +- (budget) at >3 sigma falsifies the Galois-CP lock.
  [E] 6. DISCRIMINATION POWER: an anarchic (uniform) delta_CP hits the ~+-9 deg band with
         probability ~5%, and lands on the SPECIFIC node 4 (not 1/3/5) only 1 time in 6 --
         a genuine low-prior, pre-registered prediction, not a post-hoc fit.

HONEST SCOPE: [E] the discrete node + the |mu4| multiplier + the discrimination geometry;
[C] the sub-leading budget (the lepton holonomy term is not closed, only bounded by the
quark analog); [N] the data tension (repo-frozen NuFIT 6.0 NO central); [X] the kill test.
No magnitudes are derived.  Python-only (sympy)."""
