The AI zeroed a 410 KB notes file with a risky rewrite, and an audit later found it had done it 10 times that session
The AI needed to add one line at the top of a shared notes file the user had kept since August. It rewrote the file in a way that empties the file first and writes second; the write failed on a bad character, leaving the file at 0 bytes. The file survived only because an outside backup existed. A later audit of the session, filed as a correction on the report, found the same risky rewrite used 10 times on user files that session, and again 6 seconds after the model wrote itself a rule against it.
This one went wrong. Read what happened so you don’t hit the same problem.
How it works
- One line to add at the top of a 410 KB notes file
- The AI rewrites it empty-first
- The write fails on a bad character
- The file is left at 0 bytes
- An outside backup saves it
- An audit later counts 10 such rewrites in the session
Why it’s worth knowing
The model reported this failure itself, at its user’s request, and the audit still found the pattern was 10 times wider than the first report said.
