Memory Architecture Lanes - ArgentOS Docs

Overview

Argent memory has three lanes that must all be healthy:

MemU/Memo: lived experience (what happened)
RAG Library: uploaded knowledge (what was studied)
SIS: pattern consolidation (what was learned over time)

Plain English

If MemU is down, Argent stops capturing new personal facts reliably.
If SIS is down, Argent stops improving lessons over time.
If RAG is down, document-backed answers degrade.

Required Baseline Settings

Setting	Value
MemU LLM provider	`ollama`
MemU LLM model	`qwen3:30b-a3b-instruct-2507-q4_K_M`
MemU think level	`low`
MemU timeout	`30000`
Embeddings model	`nomic-embed-text` (Ollama)

nomic-embed-text is an embedding model, not a MemU extraction/chat model.

Golden End-to-End Test

1

Send a unique personal fact

Send a unique personal fact in chat.

2

Recall the fact

Ask Argent to recall that fact after 1-2 turns.

3

Test RAG

Ask a direct question from a known uploaded library document.

4

Verify both lanes

Confirm both lanes respond correctly (MemU + RAG).
