Accepted risks
Findings the reviewer chose to accept rather than block on.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| provenance | publisher-changed | AI (provenance): bcoe (Ben Coe) is the original author of nyc per package.json; this is a legitimate return to original maintainer, not a compromise. | ai | |
| dependencies | unvetted-dep:istanbul-lib-source-maps | AI (dependencies): istanbul-lib-source-maps is a core Istanbul ecosystem dependency that nyc has used across many versions; stable false positive for this package. | ai | |
| semgrep | semgrep:dynamic-require | AI (semgrep): Dynamic require in nyc is the intentional --require flag feature, allowing users to pre-require modules before instrumentation. This is documented behavior stable across all versions. | ai | |
| bogus-package | bogus-package | AI (bogus-package): Isaac Schlueter is a legitimate historical contributor to nyc; his presence as a contributor does not indicate spam. False positive for this package. | ai |
