brookmd 0.22.2

A final performance pass over the Rust core before the platform rollout: profiling found two hot spots shared by every streaming document shape, and fixing them makes streaming 7–24% faster across all benchmarked shapes — byte-identical output, native and WASM builds alike.

  • the scanner's newline search (line_end), the hottest primitive in the engine (re-run by every block probe on every line), now scans 8 bytes per step (SWAR) instead of one;
  • the inline renderer copies runs of plain text with a single push_str instead of per-byte dispatch + escape calls.

Verified byte-identical by the full battery: CommonMark + GFM spec goldens, wire-envelope goldens, chunk-independence property tests, and the streaming-parity fuzzer. Ships as brookmd@0.22.2 on npm and brookmd-core 0.22.1 on crates.io.

This release window also includes brookmd-react-native@0.1.0 — the first npm publish of the React Native package, gated on the app-level end-to-end CI run (a real RN 0.86 release build streaming the wire goldens through the native parser on an Android emulator and an iOS simulator, byte-asserted). See 0.22.1's notes in the changelog for the Metro/Hermes compatibility fixes that e2e gate surfaced.

Prebuilt native artifacts (experimental)

CI-built binaries for the native bindings, rebuilt from the optimized core — the Swift/Kotlin/C-ABI/Flutter bindings are not yet on package registries. All emit the same versioned wire (WIRE.md v1.1.0), pinned by per-language golden tests.
