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 |
|---|---|---|---|---|
| source-diff | source-size-tripled | AI (source-diff): Size increase reflects addition of the bundled esm.js runtime library, which is the package's primary artifact. Expected for this package. | ai | |
| source-diff | obfuscated-file:esm.js | AI (source-diff): esm.js is the package's canonical webpack bundle; minified distribution is the documented and expected format for this package across all versions. | ai | |
| semgrep | semgrep:dynamic-require | AI (semgrep): Dynamic require in webpack bundle module loader shim — standard webpack output pattern, not a real risk for this package. | ai | |
| typosquat | typosquat.levenshtein:qs | AI (typosquat): @std/esm is a legitimate, well-established ES modules package by jdalton; Levenshtein proximity to 'qs' is purely coincidental and not a typosquat. | ai | |
| typosquat | typosquat.levenshtein:jest | AI (typosquat): @std/esm is a legitimate, well-established ES modules package by jdalton; Levenshtein proximity to 'jest' is purely coincidental and not a typosquat. | ai | |
| semgrep | semgrep:api-obfuscation-reflect | AI (semgrep): @std/esm is a module loader that legitimately uses Reflect.get() to hook into Node internals. This is a known, documented characteristic of the bundled esm.js distribution — stable false positive for this package. | ai | |
| provenance | no-provenance | AI (provenance): Package is 3178 days old, predating Sigstore provenance. Published by highly reputable maintainer jdalton with a long track record. No provenance is expected and not a risk signal here. | ai |
