We present the deepest clustering analysis of early galaxies to date, analyzing $N_{ \rm{ g}} \simeq 6500$ photometrically-selected Lyman Break Galaxies from JWST's Advanced Deep Extragalactic Survey (JADES) to reveal how galaxies and dark matter evolved during cosmic dawn ($5 \leq z < 11$). Using halo occupation distribution (HOD) modeling of the two-point angular correlation function, we trace the galaxy-halo relationships across the first billion years of cosmic history. Our analysis reveals that galaxies at $z = 10.6$ reside in dark matter halos over an order of magnitude less massive ($M_{ \rm{ h}} \sim 10^{ 10.12} M_{ \odot}$) than their counterparts at $z = 5.5$ ($M_{ \rm{ h}} \sim 10^{ 11.45} M_{ \odot}$), while exhibiting correspondingly higher effective bias values ($b_{ \rm{ g}}^{ \rm{ eff}} = 8.13^{ +0.04}_{ -0.02}$ compared to $5.64^{ +0.10}_{ -0.13}$). Correspondingly, the satellite galaxy fraction hints at a declining trend with decreasing redshift, reaching $<1\%$ by $z \sim 5-6$. However, the significant systematic and random uncertainties in the data-model comparison prevent us from drawing robust conclusions on the evolution - if any - of the satellite fraction during the epoch of reionization. These results provide the first view of the coevolution between galaxies and dark matter evolved at redshift $\gtrsim 10$, offering additional and independent constraints on early galaxy formation models tuned to reproducing luminosity function evolution.
