Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
source-diff large-new-source-files AI (source-diff): Major version bump (1.x → 18.x) for an established KA package; large file count increase reflects architectural consolidation, not injected code. ai
publish-pattern new-deps-added AI (publish-pattern): New deps are all KA first-party packages plus tiny-invariant (well-known utility); consistent with major version refactor of Perseus framework. ai
source-diff source-size-tripled AI (source-diff): 31x size increase is explained by major version evolution consolidating multiple sub-packages; publisher is trusted KA account with long track record. ai
source-diff obfuscated-file:dist/index.item-splitting.js AI (source-diff): Standard minified CJS build output. Same legitimate math library code as the ES module variant. Normal build artifact for this package. ai
provenance publisher-changed AI (provenance): Khan Academy legitimately transitioned to GitHub Actions CI/CD publishing; SLSA provenance attestation confirms builds come from official Khan/perseus repo. This is a stable organizational change. ai
provenance missing-githead AI (provenance): GitHub Actions publish environment doesn't set gitHead; SLSA Sigstore attestation provides stronger commit-level provenance than gitHead field. ai
source-diff obfuscated-file:dist/es/index.item-splitting.js AI (source-diff): Standard minified build output for Khan Academy's math library. Code samples show legitimate educational math utilities (approximateEqual, KAS integration). Normal build artifact. ai
dependencies unvetted-dep:@khanacademy/pure-markdown AI (dependencies): First-party Khan Academy package from the same Perseus monorepo org; unvetted flag is a pipeline artifact, not a real risk. ai
dependencies unvetted-dep:@khanacademy/kas AI (dependencies): First-party Khan Academy package from the same Perseus monorepo org; unvetted flag is a pipeline artifact, not a real risk. ai
bogus-package bogus-package AI (bogus-package): Internal Khan Academy monorepo package; sparse README and no keywords are expected for org-internal packages, not spam indicators. ai
