Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance missing-githead AI (provenance): Package has SLSA provenance attestation via GitHub Actions; missing gitHead is a minor metadata gap, not a supply chain risk. ai
provenance publisher-changed AI (provenance): Cloudflare org migrated to GitHub Actions CI publishing with SLSA attestation; stable pattern for this package. ai
publish-pattern new-deps-added AI (publish-pattern): @cloudflare/codemode is a first-party Cloudflare package in the same monorepo; not a suspicious third-party dep. ai
bogus-package bogus-package AI (bogus-package): Placeholder/namespace-reservation package under @cloudflare; empty payload is intentional, not spam. ai
npm-metadata suspicious-initial-version AI (npm-metadata): 0.0.0 is used for namespace reservation by Cloudflare; not indicative of malicious intent here. ai
dependencies unvetted-dep:@cloudflare/codemode AI (dependencies): First-party Cloudflare package from the same monorepo; low risk for this package. ai

HIGH Publisher changed: threepointone → GitHub Actions (on 2026-03-19) provenance

This version was published by a different npm account than previous versions on 2026-03-19. This could indicate a legitimate maintainer transition or an account compromise.
