Aionis records which memory was surfaced, suppressed, used, and followed by which outcome. That creates the dataset for measuring memory admission quality.
The dataset other memory layers usually miss
A retrieval log can say what was fetched. It often cannot say what was admitted, what the agent actually used, what was suppressed, and which outcome followed.
Aionis records admission decisions and feedback attribution together. That turns the runtime into a source of labeled evidence for memory policy evaluation.
From rules to measurable policy
The first admission policies are deterministic and conservative. The important step is making them measurable: train and holdout splits, calibration, candidate policy comparison, and real-agent reruns.
The long-term moat is not a single rule. It is the closed loop that lets Aionis learn which memories actually helped, which hurt, and which should never reach direct use again.
