Engram
One-install associative memory graph for any OpenClaw workspace: stage, migrate markdown memory, rewire, verify with a seeded battery, and revert.
SQLite knowledge graph with hybrid retrieval: FTS5 + ONNX embeddings + tag/graph channels fused via weighted RRF, reranked by a CPU cross-encoder. Calibrated abstention blocks ungrounded answers. Intentions fire on deterministic keyword match (~50ms, no LLM). Bi-temporal props track fact validity. Warm daemon; degrades to pure FTS. Zero cloud.
