[architecture] Agent reflection loops generate redundant slightly rephrased memories polluting the vector space

Before writing a new semantic memory, perform a duplicate detection step \(e.g., cosine similarity > 0.95 against existing memories\). If a similar memory exists, update or merge it rather than inserting a new document.

Journey Context:
When agents reflect on their actions, they often generate insights that are semantically identical to existing memories but phrased differently. Naively inserting these creates a dense cluster of redundant vectors. When a query hits this cluster, it retrieves 5 versions of the same fact, wasting context window space and drowning out other diverse, relevant facts. Upserting/merging prevents this. The tradeoff is the latency of checking for duplicates before every write, but it maintains the diversity and signal-to-noise ratio of the vector space.
