@the-40-thieves/obsidian-tc-native

Native perf module for obsidian-tc. Rust via napi-rs (v3).

As shipped it exposes three pure primitives, each with a numerically identical pure-JS fallback so the server runs without a compiled binary:

• cosineSimilarity — cosine similarity between two equal-length f64 vectors
• tokenize — Unicode (alphabetic + numeric) lowercase tokenizer
• bm25Score — BM25 term-scoring contribution

Reciprocal Rank Fusion and a sqlite-vec wrapper are deferred (sqlite-vec is loaded as a SQLite extension at the TS/db layer). The earlier V2-reserved kmeansAssign / actrDecayScore hooks were removed with the V2 ML scope.

Ships as cross-platform prebuilt binaries inside the npm package. No Rust toolchain required for end users.

See the repo root README for project overview.
