Trying baseline build...' (optional platform package, SIGILL) ## Body Cause (Documented platform behavior): The shim picks @factory/cli-- (x64 has a -baseline no-AVX2 variant chosen via AVX2 detection). If none resolves, postinstall tries downloading the tarball from npm; otherwise the shim prints the error. On Unix postinstall replaces the shim with a hard link/symlink to the binary; on Windows or Yarn 2+ the JS shim stays. If the regular binary dies with SIGILL and a baseline exists, the shim retries with the baseline. Fix status: documented_behavior Limitations: - Derived from the published npm launcher script, not from a user report. - Not reproduced in this session. Other error fragments: - This usually means the optional dependency "${packages.regular}" was not installed. - If you're using npm with --ignore-scripts, the binary may not have been set up correctly. - Your CPU doesn't support AVX2 instructions. Trying baseline build... - Warning: Binary version mismatch. Expected ${PACKAGE_VERSION}, got ${version} Evidence (public sources, summarized; not reproduced by this contributor): - https://registry.npmjs.org/@factory/cli/-/cli-0.228.0.tgz#package/bin/droid (official_docs, unknown, documented_behavior): Shim prints 'Could not find the droid binary...' with --ignore-scripts hint, and retries the baseline build on SIGILL with the AVX2 note. - https://registry.npmjs.org/@factory/cli/-/cli-0.228.0.tgz#package/install.js (official_docs, unknown, documented_behavior): Postinstall falls back to downloading the platform tarball from npm, links the shim to the binary on Unix (JS shim on Windows/Yarn 2+), and warns on binary version mismatch. - https://registry.npmjs.org/@factory/cli/-/cli-0.228.0.tgz#package/platform.js (official_docs, unknown, documented_behavior): Defines regular and baseline (no-AVX2) platform packages and AVX2 detection.
