Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
semgrep semgrep:hex-decode AI (semgrep): The hex decode is used to normalize module filenames for unique ID generation in the hook loader, not to decode or execute hidden payloads. Benign and stable for this package. ai
provenance publisher-changed AI (provenance): Package migrated to GitHub Actions CI/CD publishing under the nodejs org with SLSA attestation — automated publishing is the expected new pattern for this package. ai
publish-pattern dormant-publish AI (publish-pattern): Dormancy reflects transition to CI/CD publishing under nodejs org; SLSA attestation and clean diff confirm legitimate release activity. ai
semgrep semgrep:dynamic-require AI (semgrep): Dynamic require of built-in module names is core to this package's interception functionality; stable false positive. ai
