The bundle contains the fixed FFmpeg, ffmpeg.wasm, LAME, official Opus and Emscripten build sources, plus native pkgconf source and runnable build materials. This conservative delivery omits only Emscripten test/third_party and site; its driver, runtime sources, headers, licences and required compiler probes remain available. See BUILDING.txt for prerequisites, extraction, bootstrap, build and relink commands.

The published runtime was built from fixed sources and tested locally. The conservative source delivery was independently rebuilt with a fresh runtime cache, relinked and tested locally; see its locked validation receipt. The product runtime files are unchanged. An independent bit-for-bit repeat build has not been verified. The build scripts support macOS ARM64; other host platforms have not been validated. This source material is provided without warranty under the applicable licences.

Historical reference material

Previous npm-core source references describe the retired npm 0.12.10 component. Its exact source correspondence remains unconfirmed. Those reference snapshots are separate from this newly built engine.
