Original reporting by RuntimeWire, based on reverse engineering, testing.

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.
