Report #76259

[architecture] Losing the sequence of events when storing memories as independent vector chunks

Store memories as edges in a temporal graph, or append strict ISO-8601 timestamps and sequence IDs to metadata, using hybrid search \(vector \+ time-filter\).

Journey Context:
'I did X, then Y failed, then I fixed it by Z.' If stored as 3 separate vectors, the causal link is lost. Vector search might retrieve 'I fixed it by Z' without the context of what 'it' was. Storing them as a single chunk is too rigid. Temporal metadata \+ hybrid filtering \(e.g., ChromaDB where document\_time < X\) or a knowledge graph preserves causality and sequence.
