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 |
|---|---|---|---|---|
| dependencies | unvetted-dep:lezer-cpp | AI (dependencies): lezer-cpp is Marijn Haverbeke's own parser library, the foundation of CodeMirror 6. Its use as a dependency in @codemirror/lang-cpp is expected and legitimate across all versions. | ai | |
| provenance | no-provenance | AI (provenance): Marijn Haverbeke's CodeMirror packages consistently lack Sigstore provenance; this is a stable characteristic of the ecosystem, not a risk indicator. | ai |
