Description (from the catalogue, unverified)
Call before pinning or installing a specific package version in npm, PyPI or crates.io. Returns whether that exact version exists in the official registry, its publication timestamp, whether it is deprecated or yanked, its published artifact hashes, and whether an expected SRI/hex digest matches. Compares registry metadata only and never returns a safety verdict.
