How Harmonia uses it
AgentCoreMemoryBank uses the official bedrock-agentcore client. batch_create_memory_records writes at most five eligible typed facts with deterministic request identifiers and a client token. retrieve_memory_records searches /harmonia/{workspace_id}/{brand_id}/facts with a bounded result count.
Every fact carries a typed reference to an operator decision, receipt, verification or learning. Retrieval rejects a foreign namespace or mismatched workspace/brand evidence. Writes reject cross-scope candidates and incomplete provider results. Raw sources, prompts, transcripts and generated drafts are not memory facts.
Authority and errors
Memory is advisory context. It cannot prove that an effect happened, approve work or bypass current evidence validation. HARMONIA_ALLOW_PAID_AWS gates native Memory access. Failed or ambiguous writes remain unresolved; the client does not fabricate retained records.
Evidence status
agent/harmonia_agent/memory_bank.py implements the contract. Worker and runtime roles require the matching scoped Memory permissions. Native API wire shapes and scope tests are local evidence; authenticated Memory read/write in this AWS edition remains unverified.Last modified on September 14, 2026
