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 |
|---|---|---|---|---|
| typosquat | typosquat.levenshtein:qs | AI (typosquat): ssf is a legitimate SheetJS package (Spreadsheet String Format), 4500+ days old. Levenshtein proximity to 'qs' is purely coincidental; no impersonation intent. | ai | |
| phantom-deps | phantom-dep:frac | AI (phantom-deps): frac is bundled into ssf's output rather than imported at runtime — standard SheetJS build pattern. Not a phantom dependency in practice. | ai |

provenance
Package was published without Sigstore provenance. Only ~12% of npm packages have provenance, so this is common but not ideal.
