Supply chain provenance
Status for the latest visible version.
Without SLSA provenance there is no cryptographic link between this tarball and the public source — the axios compromise (March 2026) relied on exactly this gap.

Findings the reviewer chose to accept rather than block on.
| Source | Rule | Reason | Accepted by | When |
|---|---|---|---|---|
| provenance | publisher-changed | AI (provenance): bcoe → oss-bot is a documented, legitimate transition for Ben Coe's packages to automated CI publishing. oss-bot has strong track record (368 approved). Stable for this package. | ai | |
| provenance | missing-githead | AI (provenance): Missing gitHead is consistent with the switch to automated oss-bot publishing environment. Not indicative of tampering for this package. | ai | |
| maintainer-change | maintainer-added | AI (maintainer-change): oss-bot added as maintainer is part of the legitimate bcoe → oss-bot automation transition. No compromise indicators. | ai | |
| publish-pattern | new-deps-added | AI (publish-pattern): @istanbuljs/schema is a legitimate Istanbul ecosystem package; adding it to a coverage tool is expected and benign. | ai | |
| phantom-deps | phantom-dep:uuid | AI (phantom-deps): uuid is properly declared in dependencies and used by c8; false positive for this package. | ai | |
| dependencies | unvetted-dep:@c88/v8-coverage | AI (dependencies): @c88 is Ben Coe's own npm scope (same author as c8); this is a first-party dependency, not a suspicious third-party package. | ai | |
| dependencies | unvetted-dep:chrome-remote-interface | AI (dependencies): chrome-remote-interface is the standard DevTools Protocol client; its use is expected and appropriate for a V8 coverage tool like c8. | ai | |
| dependencies | unvetted-dep:spawn-wrap | AI (dependencies): spawn-wrap is a well-known child process instrumentation utility; its use is expected for a coverage tool that wraps test runners. | ai | |
| typosquat | typosquat.levenshtein:qs | AI (typosquat): c8 is a well-known Node.js coverage tool, not a typosquat of qs. The name is intentional (C8/V8 coverage). | ai | |
| typosquat | typosquat.levenshtein:pg | AI (typosquat): c8 is a well-known Node.js coverage tool, not a typosquat of pg. The name is intentional (C8/V8 coverage). | ai | |
| semgrep | semgrep:base64-decode | AI (semgrep): Base64 decoding is used to parse base64-encoded source map data URIs, a standard and expected operation for a coverage/source-map tool. | ai |
