When Old Facts Return: Re-Reads, Reverts, and the Limits of Temporal Memory

Key points

• A re-read of an old source and a genuine revert can produce the same observed sequence of values while requiring opposite current answers.1
• We study this ambiguity on 130 extractor-selected atomic transitions derived from software fixes.1
• In the ordinary transition condition, identity-based temporal memory reaches 98.5% model-judged accuracy with zero observed errors under a literal stale-value proxy.1
• Two supporting studies examine exposing retired history to the answer model and supplying current source for changed behavior.1

  A memory system can retire an obsolete value and later restore it merely because the same old statement appears again.

  A re-read of an old source and a genuine revert can produce the same observed sequence of values while requiring opposite current answers.
