Remark. Reuse can change optimization without enlarging evidence [ftip-007V]
A replay schedule can reweight records, reduce optimization error on the fixed pool, or produce a different update proposal in the sense of Definition [ftip-006C]. Those are genuine computational effects. They do not add a label, preference, verifier result, or environment transition to the fixed evidence. Fresh optimizer randomness is likewise not feedback about the latent world.
This distinction prevents sample reuse from being counted as feedback acquisition. It does not imply that replay is useless; it isolates the source of any benefit as further computation on already acquired records.
