Lummenna
記憶與上下文框架，以「記憶宮殿」結構（房間、位置、區塊）組織記憶，採用混合檢索、管理記憶衰減，並完全在客戶硬體上執行，不依賴雲端。嵌入透過 ONNX Runtime 在本機執行，儲存為單一檔案 SQLite，整合項目包括 LangGraph checkpoint saver、LangChain 轉接器、MCP 伺服器與 REST API。

No full-corpus BEIR/MTEB submission or external memory-system comparison is committed.
01 / Structure
Rooms, loci, chunks
Memories carry location, provenance, validity, value, and retrieval state instead of living in an undifferentiated vector collection.
Community02 / Retrieval
Signals, then fusion
SQLite FTS5, dense vectors, optional graph traversal, and reciprocal rank fusion form the retrieval path.
Community03 / Context
Budgeted assembly
Retrieved memories are ranked and assembled into bounded prompt context with explicit truncation behavior.
Community04 / Lifecycle
Retention has pressure
Time decay, interference, and budget-driven precision changes prevent an unbounded store from masquerading as useful memory.
Community05 / Interfaces
Use the same palace
Python, MCP, FastAPI, LangChain, and LangGraph adapters connect agents to the same underlying memory model.
Community06 / Controls
Enterprise boundaries
Encryption at rest, tenant isolation, compliance operations, and advanced P2P controls are license-enforced Pro capabilities.
Pro01 / Organize
Place memory
Store a chunk in a named room and optional locus, with provenance and temporal validity recorded beside it.
02 / Retrieve
Fuse evidence
Lexical and semantic candidates are combined, reranked, tenant-scoped, and reinforced when used.
03 / Maintain
Release deliberately
Scheduled decay and budget passes alter value and precision according to explicit, inspectable rules.
