Implements append-only columnar storage with linked-value semantics for efficient deduplication and multi-value aggregation, using page-based serialization with separate key, address, and value streams. Provides text analysis utilities including vectorization, bag-of-words processing, and string similarity operations alongside CLI tools for lexicon building. Targets .NET with minimal dependencies and supports both primitive and custom key types via deterministic hashing and binary search for fast lookups.
