PL3-memory-substrate · Actions 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 Where does your codebase stand? Click a level to mark your current maturity. 0 Absent Your level No memory infrastructure 1 Nascent Your level Some substrate exists (e.g. docs only); no unified retrieval 2 Operational Your level Hybrid substrate in place; agent can retrieve across types via single MCP interface 3 Compounding Your level Memory utilisation rate is measured; retrieval relevance is tracked; substrate evolves based on what agents actually retrieve ← Previous PL3-agent-queryability Agent queryability Next → PL3-source-control Source control interaction
