Report #13871

[architecture] Vector similarity search fails to answer temporal or sequential questions like 'what happened after X?'

Augment vector embeddings with temporal metadata and use hybrid search \(vector \+ time-range filtering\), or maintain a separate sequential/episodic graph that preserves the chronological links between events.

Journey Context:
Embeddings collapse the meaning of a text into a static vector, destroying the sequential relationship between events. If an agent needs to debug a sequence of events \(e.g., 'what error occurred after the deployment?'\), pure vector search just finds 'deployment' and 'error' chunks without knowing the order. The tradeoff is the complexity of maintaining a temporal index/graph vs. the inability to answer 'when' queries. You must store timestamps and enforce chronological constraints during retrieval.
