Report #1562

[architecture] Relying solely on vector similarity for temporal or causal questions

Augment vector embeddings with strict temporal metadata \(timestamps\) and causal links \(parent/child IDs\). Use a two-step retrieval: semantic search to find the anchor, then graph or temporal traversal for subsequent events.

Journey Context:
Vector embeddings destroy temporal sequence and causality. 'I deployed v1' and 'I rolled back v1' have nearly identical embeddings but opposite meanings. If an agent needs to know what happened \*after\* an event, cosine similarity will fail. You must store memories in a structure that preserves time and causality, querying via semantic search for the 'what' and graph/time traversal for the 'when/why'.
