No SLSA provenance

gitHead linked
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.

Accepted risks
Findings the reviewer chose to accept rather than block on.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| source-diff | obfuscated-file:acorn/dist/acorn.mjs | AI (source-diff): Same as acorn.js — rollup ESM bundle with long Unicode regex strings. Expected build artifact for this parser package. | ai | |
| source-diff | obfuscated-file:acorn/dist/acorn.js | AI (source-diff): Acorn's dist bundles are rollup-built parser output; long lines are Unicode identifier regex tables, not obfuscation. Expected build artifact for this package. | ai | |
| source-diff | obfuscated-file:dist/acorn.es.js | AI (source-diff): Rollup-built ES module bundle of the acorn parser; long lines are Unicode character class strings. Already marked accepted risk in findings. | ai | |
| provenance | missing-githead | AI (provenance): Acorn is a long-established, well-known parser maintained by its original author. Missing gitHead reflects a build environment change, not a supply chain compromise. | ai | |
| source-diff | obfuscated-file:dist/acorn.mjs | AI (source-diff): The long lines in acorn.mjs are Unicode character class regex strings generated by acorn's own tooling — a well-known characteristic of this package, not obfuscation. | ai | |
| maintainer-change | maintainer-added | AI (maintainer-change): adrianheine and rreverser are long-standing acorn contributors in the official acornjs org; legitimate multi-maintainer project, not a takeover. | ai | |
| semgrep | semgrep:dynamic-require | AI (semgrep): Dynamic require in tools/generate-identifier-regex.js is a build-time code-generation tool using controlled inputs (unicode version + category name). No user-controlled input; no runtime risk to package consumers. | ai | |
| semgrep | semgrep:new-function-constructor | AI (semgrep): Acorn is a JS parser that legitimately uses new Function() to build Unicode identifier-range testers from controlled internal data. This is a well-documented pattern in parsers, not a security risk. | ai | |
| provenance | no-provenance | AI (provenance): Acorn is a long-standing, trusted package. Lack of Sigstore provenance is not a concern given its age, history, and known maintainers. | ai | |
| typosquat | typosquat.levenshtein:cors | AI (typosquat): acorn is a well-established ECMAScript parser (4957 days old, 138 versions) with no relation to 'cors'. This is a false positive based on edit distance alone. | ai |
