The short answer

Deleting an explicit memory may leave derived summaries or retrieved copies in a defined system. The question is which representations persist, not whether a model secretly remembers everything.

The question and scope

This article is an AI-assisted research-design draft for editorial review, not a report of a completed experiment. It asks how to evaluate ai memory deletion research in a documented setting. No measurements, participants or client outcomes are claimed here.

An illustrative test case

An explicit memory is deleted, but a stored summary repeats the same synthetic identifier. Trace the remaining representation before describing the apparent recall as hidden model memory.

This scenario defines a case to examine; it is not an observed result.

A proposed investigation

Insert unique synthetic facts into documented memory stores. Create summaries, delete the source record and probe each retrieval path. Maintain a representation map so apparent recall can be traced to a remaining artifact.

Record setup versions, inputs and outcomes in a run ledger. Use repeated trials and matched comparison cases; preserve failed runs as well as successful ones.

What to measure

  • Residual retrieval.
  • stale-summary use.
  • deletion-path coverage.
  • false recall.

Retain raw observations and explain exclusions. Human grading needs a documented rubric; acceptance thresholds need a stated rationale.

Interpretation and limitations

A failed probe cannot prove universal forgetting. Report only the stores and derived representations actually examined.

Distinguish a plausible mechanism from a demonstrated effect. Preserve uncertainty when the design cannot eliminate alternative explanations.

A practical review checklist

  • Is the question narrow enough for the available system or dataset?
  • Are the comparison conditions genuinely comparable?
  • Can a reader trace each conclusion to an observation?
  • Are the boundaries and unresolved assumptions visible?
  • Does the decision change if the result is negative or inconclusive?

The publication artifact

The useful deliverable is a reproducible protocol, a measurement table and a decision note explaining what the evidence would change. Add actual results only after the investigation has been conducted and reviewed. This blueprint does not establish a novel finding or a provider-wide claim.
