Interesting experiment. Lets see, I believe the 13 uS is approximately 13 ppm, the solubility limit of silver oxide according to my CRC handbook. So that is likely easy to explain, any silver oxide that did not dissolve likely remained on the electode.
Silver oxide will "develop" depositing onto silver particles under the right conditions. The liquid needs to be alkaline (silver oxide has a ph of 7.22 according to Baker Chemical), and normally there would need to be something to act as a developer. It appears that H2O2 can under some circumstances act as a developer. So that would explain the flakes as well. Once you ended the electrolysis, and all the H2O2 was dissipated, you would be left with photo sensitive silver oxide in solution, and flakes on the bottom. I am not sure what happened to the flakes to make them into black balls, but upon exposure to light the silver oxide would convert to silver atoms and particles, which would explain the final liquid result, which was likely a combination of colloidal silver, silver atoms, and silver oxide..
