Provenance

No SLSA provenance npm registry signatures No source commit

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.

SourceRuleReasonAccepted byWhen
provenance publisher-changed AI (provenance): Publisher change from ryanflorence to chancestrickland is a documented, legitimate handoff within React Training / Reach UI org. chancestrickland is the known long-term Reach UI maintainer. ai
maintainer-change maintainer-added AI (maintainer-change): chancestrickland and mjackson (Michael Jackson) are both React Training co-founders/core maintainers. Addition is a legitimate organizational change, not a compromise. ai
source-diff source-size-tripled AI (source-diff): Size increase reflects migration to tsdx build tooling producing CJS, ESM, and UMD bundles. Multiple output formats naturally explain the 4.7x size increase. ai
provenance missing-githead AI (provenance): Missing gitHead is consistent with the tsdx tooling migration changing the publish environment. No malicious indicator. ai
email-domain unclaimed-email:ryanflorence AI (email-domain): The 'email' field contains '@ryanflorence', a social handle placeholder, not a real email address. No actual email domain to hijack; finding is a false positive for this package. ai
