Sb Memory Systems Reference

Domain-theory reference for the second-brain plugin's memory mechanisms AS BUILT HERE: BM25 field-weighted scoring, RRF hybrid fusion and the post-RRF-boost bug class, the ONNX embedding pipeline and its bm25-only degradation contract, MinHash near-duplicate detection (capture NOOP/UPDATE, dream DEDUPLICATE, FORGET cross-check), deterministic label-propagation clustering, the bi-temporal edge store (assert/invalidate, supersedes), structural-importance-only forgetting, the REFLECT operation, the shipped PageRank code-map, and the lethal-trifecta consolidation security model. Load it when a task touches ranking/scoring math, similarity thresholds, dedup/forget/cluster/reflect semantics, graph validity intervals, or when deciding whether a proposed boost/weight/decay is safe — and when evaluating an idea borrowed from mem0/Letta/Graphiti/GraphRAG/Generative-Agents papers (the borrow ledger records each verdict). Do NOT load it for wiring, data paths, or hook plumbing (use sb-architecture-contract), for external novelty/positioning claims (use sb-external-positioning), or for live-failure triage (use sb-debugging-playbook).
