CP violation (CPV) in $D^0-\overline{D^0}$ mixing is described terms of the dispersive and absorptive `weak phases' $\phi_f^M$ $\phi_f^\Gamma$. They parametrize CPV originating from interference $D^0$ decays with without mixing, respectively, for conjugate hadronic final states $f$, $\bar f$. These are distinct separately measurable effects. For eigenstate states, indirect only depends on (dispersive CPV), whereas $\phi_f^\Gamma$ (absorptive CPV) can be probed non-CP states. Measurements state dependent phases $\phi_f^M$, determine intrinsic $\phi_2^M$ $\phi_2^\Gamma$. The latter arguments amplitudes $M_{12}$ $\Gamma_{12}$, relative to their dominant ($\Delta U=2$) $U$-spin components. experimentally accessible due approximate universality: SM, extensions negligible new Cabibbo favored/doubly suppressed (CF/DCS) decays, deviation $\phi_f^{M,\Gamma}$ $\phi_2^{M,\Gamma}$ CF/DCS $D^0 \to K^\pm X$, below $10\% $ K_{S,L} X$ (up precisely known $O(\epsilon_K)$ corrections). In Singly Suppressed (SCS) QCD pollution enters at $O(\epsilon)$ breaking significant, but $O(\epsilon^2)$ average over $f=K^+K^-$, $\pi^+\pi^-$. SM estimates yield $\phi_2^M, \phi_2^\Gamma = O(0.2\%)$. A fit current data allows $O(10)$ larger $2\sigma$, physics. based naively extrapolated experimental precision suggests that sensitivity $\phi_2^{M}$ $\phi_2^{\Gamma}$ may achieved LHCb Phase II upgrade.
