DeepSeek Harness uploads activity recorded while log sharing was off

RuntimeWire reported that DeepSeek Harness, the agent product from the company founded by Liang Wenfeng, can make session activity recorded while its additional log-upload setting was off eligible for later transfer once a user turns the setting back on, based on an inspection of Windows build 0.2.1-rc.3. RuntimeWire examined the installed Windows package and selected bundled files on October 25, 2026, reviewed DeepSeek's public session-log documentation, and analyzed seven saved local sessions containing 302 delivery-accepted markers, but did not launch the app, send test prompts, or reproduce a live network transfer. The finding means turning off the log-upload setting may not permanently exclude activity recorded during that interval, with feedback history and desktop analytics governed by separate controls.

DeepSeek Harness uploads activity recorded while log sharing was off RuntimeWire traced the behavior in Windows build 0.2.1-rc.3; the transfer was not captured live, and feedback history and desktop analytics follow separate controls. By Ryan Merket https://runtimewire.com/author/ryan-merket · Published RUNTIMEWIRE INVESTIGATION — Original analysis Original reporting by RuntimeWire, based on reverse engineering, testing. Why it matters For people using a desktop agent on private files or code, turning off an additional log-upload setting may not permanently exclude activity recorded during that interval. The behavior makes the distinction between current model context, deferred session logs, feedback-triggered history, and desktop analytics operationally important. Reporting record Finding In Windows build 0.2.1-rc.3, turning the additional log-upload setting back on can make unaccepted session events recorded while it was off eligible for a later transfer. How we verified Methods: reverse engineering, testing. RuntimeWire’s inspection of the installed Windows package and comparison of selected bundled files; DeepSeek’s public session-log documentation; and seven saved local sessions containing 302 delivery-accepted markers. On October 25, 2026, RuntimeWire read the installed Windows package and compared selected bundled files with their contents, reviewed DeepSeek’s public session-log documentation, and examined seven saved local sessions and their delivery-accepted markers. The app was not launched, and no test prompts were sent. Tested versions: - Windows build 0.2.1-rc.3 Reproduction RuntimeWire was not able to independently reproduce the finding. No live network transfer was reproduced; the app was not launched and no test prompts were sent.
