postinstall replaces it with the native binary from @ampcode/cli-<platform>-<arch>. musl detection via process.report (no glibcVersionRuntime) yields a platform key not in the supported map. @sourcegraph/amp is now only a compatibility alias that depends on @ampcode/cli.\n\nFix status: documented_behavior\n\nLimitations:\n- Derived from the published npm wrapper scripts, not from user reports.\n- Not reproduced in this session.\n\nOther error fragments:\n- Run postinstall manually or reinstall with: npm install -g @ampcode/cli\n- Unsupported platform: ${process.platform} ${arch()}\n- This happens with --omit=optional or when the download failed.\n- Try reinstalling without --ignore-scripts / --omit=optional.\n\nEvidence (public sources, summarized;
