Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
provenance publisher-changed AI (provenance): JupyterLab migrated publishing to GitHub Actions CI with SLSA provenance; this is a legitimate infra change, not a takeover. ai
publish-pattern dormant-publish AI (publish-pattern): Long gap explained by CI/CD pipeline migration; SLSA attestation confirms legitimate automated publish. ai
semgrep semgrep:dynamic-require AI (semgrep): Build utility reads package.json files dynamically by path — expected pattern for this tooling. ai
semgrep semgrep:child-process-import AI (semgrep): Build/repo management tool legitimately shells out to npm and other CLI tools. ai
semgrep semgrep:shady-links-raw-ip AI (semgrep): 0.0.0.0 is a localhost binding for a local Verdaccio test registry, not an external exfiltration endpoint. ai
phantom-deps phantom-dep:verdaccio AI (phantom-deps): Verdaccio is used as a local test registry; referenced in config but not imported directly — stable false positive. ai
