NUMERICAL EMERGENCE SCAN (2026-06-15; the numerical sibling of QGEO.MARKS.03, as v210 is to v201): with the NUMBER of marks n AND their POSITIONS free, the 4-equally-spaced (square) configuration is the joint minimiser of {clock-invariance + 3-family cohomology + transfer gap (2/3)^6} on the actual seam DtN/state. (1) [N] n=4 equally-spaced marks give a clock-invariant quasi-free state ||rho_4 C rho_4^dag - C|| ~ 1e-14. (2) [N] family count selects n=4: scanning n in {2..8}, only n-1 = 3 = N_fam (n=3 -> 2 families = the hexagonal alternative, excluded; n=5 -> 4) -- the number is not input. (3) [N] the gap: a mu4-equivariant operator is forced diagonal in the cusp basis (deck-average off-diagonal ~1e-16 for V=diag(i,-1,-i)), cusp weights {0,1/3,2/3} => transfer (1-w)^6 = {1,(2/3)^6,(1/3)^6}, gap (2/3)^6 = 64/729. (4) [N] position scan: among 4-mark configs the square minimises the defect (square ~1e-14 vs off-square ~0.4) -- the operator-level v200 theta=pi/2. (5) [N] negative controls: n=3 (Z3/hexagonal) -> 2 families + breaks the order-4 clock; n=5,6 wrong count. (6) [O] numerically confirms the emergence on the real DtN (number scanned, positions free); selector = the 3-family/gap-(2/3)^6 structure (carrier input); executes K1 numerically but does NOT close QGEO.REALIZE.01 (the order-4/N_fam input stays irreducible, v153/v181); complements v216. Python-only
Recorded status: Numerical [N] (emergence confirmation on the real DtN/state) + premise [O] (selector is carrier input)
