buble
The blazing fast, batteries-included ES2015 compiler
Supply chain provenance
Status for the latest visible version.
Without SLSA provenance there is no cryptographic link between this tarball and the public source — the axios compromise (March 2026) relied on exactly this gap.

Findings the reviewer chose to accept rather than block on.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| phantom-deps | phantom-dep:minimist | AI (phantom-deps): minimist is used by the CLI binary (bin/buble); declared correctly in dependencies. | ai | |
| phantom-deps | phantom-dep:vlq | AI (phantom-deps): vlq is used by the bundled dist output; declared correctly in dependencies. | ai | |
| source-diff | obfuscated-file:dist/buble-browser.es.js | AI (source-diff): Rollup-bundled output of buble's source; long lines are from bundling, not obfuscation. Source maps included. | ai | |
| source-diff | large-new-source-files | AI (source-diff): Package ships src/ and dist/ with source maps; large file count is normal for a compiler/transpiler. | ai | |
| source-diff | obfuscated-file:dist/buble.deps.js | AI (source-diff): Standard Rollup UMD bundle with inlined deps (acorn, etc.); long lines from bundled code, not obfuscation. | ai | |
| source-diff | obfuscated-file:dist/buble.es.js | AI (source-diff): Standard Rollup ES module build output; long lines from bundled code, not obfuscation. | ai | |
| bogus-package | bogus-package | AI (bogus-package): The S_KNOWN_SPAM_PUBLISHER signal for 'marijn' is a false positive; Marijn Haverbeke is a highly reputable developer (acorn, CodeMirror). Buble is a legitimate, well-known ES2015 compiler. | ai | |
| provenance | publisher-changed | AI (provenance): mourner is Rich Harris, the original author of buble. The transfer from adrianheine back to mourner is a legitimate maintainer transition consistent with the project's history. | ai |
