FR.KOIDE.07
OPERATOR ORIGIN OF THE KOIDE SOURCE->POLE FACTOR 53/54 (external-review proposal 2026-06-14, validated; upgrades the FR.KOIDE.03 conjecture from a bare arithmetic guess 1-1/(2 N_fam^3) to an exact operator identity on the carrier): u_pole/u_source = a^T (R+Q) 1 / (2 * 1^T R a) = 53/(2*27) = 53/54. (1) THE CUBIC FAMILY BLOCK [I]: 1^T R a = 27, the E6xA2 flavor-shadow split 248 = dim E6 + det R + 2(1^T R a)N_fam = 78 + 8 + 2*27*3, so 2*27 = 54 is the sheet-doubled denominator. (2) THE MISSING CORNER [I]: the Sheet Diamond has present corners R=M(0,0), K=M(1,-1), L=M(2,0) and the ABSENT corner F=R+Q=M(1,1) with anchor-block determinant det B_F = 52 = dim F4 (FLAV.PENCIL.02/v80); its anchor response a^T(R+Q)1 = 53 = 52+1 (F4 shadow + singlet). (3) THE RATIO [I]: a^T(R+Q)1/(2*1^T R a) = 53/54 = 1-1/(2 N_fam^3) exactly (54 = 2 N_fam^3 = 2*27), so the two readings coincide but this one is structural, not fitted. (4) NEGATIVE CONTROL [I]: only the missing corner F gives 53 -- a^T M 1 for M in {R,Q,K,L} = {32,21,35,56}, none = 53 (specific, not generic). PHYSICAL STATUS [C]: the FACTOR is now sourced exactly; the MECHANISM (the leptonic pole-mass transfer evaluates the F corner) stays a conjecture, an F_transfer special case (F_pole: source->pole). Koide thus moves from 'near miss + conjecture' to 'operator-sourced source->pole transfer'; the prediction itself stays [C]. Cross-ref HOR.TRISECT.01 (the same Sheet-Diamond double-cover grammar carries the gravity clock, exponent ratio |Z2|)
Recorded status: Identity [I] (exact operator factor + negative control) + Physical [C] (the transfer mechanism)

Canonical status: Identity [I]: 53/54 = a^T(R+Q)1/(2*1^T R a) sourced from the missing Sheet-Diamond corner F (det B_F=52); mechanism stays [C]
