We record a single carrier hypothesis that would relate three otherwise separate facts of the fermionic sector: the exact non-observability of individual colours in the confined regime, the appearance of three massive generations, and the unit-dispersion (Koide) shape of the charged-lepton square-root masses. The proposal is one complex three-phase carrier zg = S + A\, e^i (+ 2 g/3), g = 0, 1, 2, read in two ways: its pure-phase part sums to zero over the three cube-root phases (1 + + ² = 0), a collective and exact cancellation read as a centre-neutral, triality-zero shadow of colour neutrality; its real part S + A (+ 2 g/3) is the square-root mass profile of the companion note. In this reading the singlet amplitude S is the master dial: S = 0 is the pure-phase, sum-zero regime (centre-neutral colour shadow) ; S 0 opens the real-offset regime (positive masses) ; the balanced point S = is singlet–doublet equipartition (Koide, CV = 1) ; and the phase places one generation near a node of the profile (the hierarchy). This is a speculative bridge, not a derivation. It does not derive the Standard-Model charge assignments, anomaly cancellation, or the charged-lepton masses. It identifies a candidate common origin for the colour triplet and the generation triplet, and states the explicit construction charge sheet that any realisation would have to discharge.
