Report #81641

[architecture] Agent latency compounds because every step requires a synchronous vector DB query and LLM call to decide what to remember

Decouple memory writes and background curation from the critical path. Write memories asynchronously \(fire-and-forget\) and perform memory consolidation/decay in background jobs.

Journey Context:
If you block the agent's response to wait for embedding, upsert, and deduplication, the user experience degrades significantly. Memory writes are often non-blocking from the user's perspective. Similarly, memory consolidation \(summarizing old memories\) should happen offline or during idle time, not during the user's turn. Tradeoff: eventual consistency \(memory might not be immediately available on the very next turn\), but vastly improved responsiveness.
