One prompt, three memories: building a memory-governance agent with Qwen

Short summary

When a care assistant runs for months, bigger context windows don't solve the real problem—governance does. This hackathon project layers a deterministic policy (ERINYS) between memory storage and the LLM, sorting memories into four states: selected (trusted), conflicted (contradictory), demoted (stale), and blocked (sensitive). Demo testing with Qwen prevented three synthetic PII identifiers from leaking while raw memory failed.

• •Deterministic memory governance prevents PII leakage without sacrificing response detail
• •Four-state policy filters context before LLM generation, making decisions auditable and reproducible
• •Content-agnostic architecture reusable across domains, demonstrated with Qwen on healthcare use case
