3.4 Memory substrate exists
3.4 Memory substrate exists
agent has a unified memory tool (markdown + vector DB + structured DB + event log, MCP-exposed) covering decisions, postmortems, customer-context references (pseudonymous; raw PII does not enter the memory substrate), performance baselines
Levels
Level 0
No memory infrastructure
Level 1
Some substrate exists (e.g. docs only); no unified retrieval
Level 2
Hybrid substrate in place; agent can retrieve across types via single MCP interface
Level 3
Memory utilisation rate is measured; retrieval relevance is tracked; substrate evolves based on what agents actually retrieve
