🧠 1. Long-Term Memory Interface Contract (MemoryProviderABC)

The system declares the interface specification in agent/memory_provider.py. All external vector memory storage plugins (e.g., Honcho, Mem0, SuperMemory) must implement:

  • add_memory(): Persists conversation records or variables to a remote vector store.
  • recall_memory(): Performs semantic vector retrieval before LLM interaction to inject the most relevant historical memory into the LLM context.

⚡ 2. Isolation & Multi-Thread Safe Write-Back

During batch multi-agent execution, to prevent memory overlap and cross-contamination, data writes are isolated using session ID locks, ensuring vector write transactions execute sequentially, eliminating local concurrent write contention.
