Changes in cosmic-ray transport properties connect the high-energy features in the electron and proton data.

In this Letter we simultaneously interpret the spectral feature at $\sim 10 \, \mathrm{TeV}$ in the cosmic-ray proton spectrum recently reported by the DAMPE Collaboration together with the spectral break at $\sim 1 \, \mathrm{TeV}$ measured by H.E.S.S. in the lepton spectrum as signatures of one nearby hidden cosmic-ray accelerator. We show that this interpretation is consistent with the anisotropy data as long as the rigidity scaling of the diffusion coefficient features a hardening at $\sim 200 \, \mathrm{GV}$, as suggested by the light nuclear data measured with high accuracy by the AMS-02 Collaboration. The spectral feature is applied consistently to the large-scale diffuse cosmic-ray sea as well as to the particles injected by the source.
