Patterns
Reusable structural ideas. Smaller than a method, larger than a config knob.
- Atomic notes One idea per note, each note independently understandable, linked explicitly. The structural primitive behind Zettelkasten, Evergreen notes, and most modern PKM tools.
patterns.memory_management - Cross-encoder reranker Two-stage retrieval. First, ANN search returns top-K candidates. Then a cross-encoder scores each (query, candidate) pair jointly and re-orders by relevance.
patterns.ranking - Hierarchical Navigable Small World (HNSW) Multi-layer graph index for approximate nearest neighbour search. De-facto default for vector databases when latency matters more than perfect recall.
