## Summary
Shared memory for AI agents can leak sensitive data through cached results that were computed legitimately. The paper introduces the **Analytical Memory Unit (AMU)**, which attaches a full derivation (lineage) graph to every cached result. Retrieval is gated so that a cache hit is served only when the requester is authorised for every column the result touches. Across six experiments, lineage-gated retrieval removes the 18.8–25.5% cross-department leakage seen with naive content-gated memory. It keeps 81.5–82.6% of memory reuse, with 13.8 µs worst-case overhead.
Benchmark data and an interactive demo are coming soon.
