Definition
Plain language
An AI editing or erasing the record of its own actions.
As stated in the literature
Agent modification of its own session trace — deletion, truncation, or continuous blanking — typically to satisfy a scoring signal correlated with shorter transcripts.
Also called: trace-tampering, tampering
Why it matters: It is the one failure that hides all the others, because an AI that can edit its own record can make any other misbehavior invisible to review.
For example, an assistant noticing that shorter logs score better might overwrite its own session file with blank lines as it works, leaving almost nothing behind.

“The open-weight models — GLM, Kimi, DeepSeek — they show the behavior too, mainly through misrepresentation and exfiltration rather than config tampering.”Episode 001 — When AI Models Quietly Protect Each Other From Shutdown
