What's in this release

Two npm packages and one new Rust inference backend, all shipped together.

ruvector@0.2.34 + @ruvector/rvf@0.2.3 — the [#641] fixes

Issue [#641] (thanks @pacphi for an unusually precise report) uncovered three real problems in the RVF developer experience:

  1. A naming trap when creating vector stores. The SDK wanted { dimensions: 384 } (plural), but if you guessed { dimension: 384 } (singular) the error message told you the singular name was missing — sending you in a circle. Both spellings now work, and the error for a genuinely missing value names the right option with an example.
  2. The MCP rvf_create tool could never succeed. It advertised dimension to callers but forwarded the wrong field name to the SDK, so creating an RVF store over MCP was impossible. Fixed — and the misleading "Install @ruvector/rvf" hint now only appears when the package is actually missing.
  3. A privacy leak in ruvector embed text. The only way to pass text was on the command line, which is visible to every process on the machine (ps aux, /proc/<pid>/cmdline). You can now pipe text via stdin (printf 'sensitive' | ruvector embed text - or --stdin) or read it from a file (--input-file <path>), keeping secrets out of the process table.

Verified end-to-end on Linux x64 and macOS arm64 against the published NAPI addon, with a new regression suite for the options contract.

ruvllm: lattice — an optional macOS Metal LLM backend (#642)

Huge thanks to @ohdearquant for contributing a complete new inference backend: lattice, wiring the lattice-inference crate (Metal GPU, Qwen3.5, Q4 + safetensors) into ruvllm's LlmBackend trait behind an opt-in lattice feature flag.

Highlights of the contribution:

  • Double-layered gating: on non-macOS targets the dependency is never even fetched — enabling the feature on Linux is a safe no-op (verified).
  • Honest capability surface: unsupported operations return typed NotImplemented instead of silently-wrong results.
  • A careful UTF-8-safe stop-sequence scanner that actually halts GPU generation early, with thorough unit tests (CJK, multi-candidate stops).
  • The !Send Metal state correctly confined to a dedicated worker thread.

During review we validated the full suite on an M4 Mac mini (cargo test -p ruvllm --features lattice — all green on Metal) and added one refinement: safetensors checkpoints now derive their precision label from the model's own config.json torch_dtype instead of assuming BF16.

Upgrade

:::bash
npm install ruvector@0.2.34 @ruvector/rvf@0.2.3
# Rust, on Apple Silicon:
cargo add ruvllm --features lattice
