Unverified50% confidenceOpinionExact time
In vector retrieval, two documents with similar content get nearly identical embeddings, and the system cannot tell which one has been invalidated; whereas a SUPERSEDES edge in the graph makes 'outdated' a traversable, citable, auditable fact.

UnverifiedThe Supersedes field is the mechanism by which memory systems handle information updates, letting a new write explicitly declare which old record it replaces, to avoid both old and new versions remaining in the store at the same time and causing retrieval conflicts; the similarity gate itself cannot distinguish corrections from restatements, and must rely on such explicit annotation.70% similarUnverifiedA "ghost document" phenomenon exists: outdated process descriptions may rank higher than the latest version due to their dense keywords, while the retrieval system cannot detect document expiration.66% similarUnverifiedFile-based memory is inferior to dedicated databases in retrieval efficiency and concurrent-write consistency, and still needs to be evaluated in scaled scenarios.66% similarUnverifiedVector retrieval excels at locating semantically relevant content across massive, heterogeneous document sets, whereas folder-based retrieval relies on the model's understanding and filtering of files, and at large scale its recall quality and efficiency may decline.65% similar
