This is super useful. I really like the idea of treating memory as an SLO surface rather than just a storage layer.

Retrieval precision@k against a small gold set is a very strong suggestion. That feels like a much better early warning signal than just latency or token usage, because those can look fine while memory quality is quietly degrading.

Write amplification and duplicate-rate tracking also make a lot of sense. Near-duplicate buildup is exactly the kind of thing that makes a memory system look healthy on the outside while slowly poisoning recall underneath.

I have basic duplicate detection in /nemp:health, but I haven’t framed it yet in terms of retrieval quality metrics the way you described. That’s a really good direction. Thank you
