Sbom Maker

SBOM Maker

Turn one lockfile into a verifiable component inventory. The caller supplies the parsed lockfile; nothing is fetched, so the same input always seals the same SBOM. This is the inventory layer of the security pipeline: sbom-maker derives what is present, cve-audit detects what is vulnerable.

Procedure

1. Native data.digest binds the exact lockfile object; the SBOM serial number and metadata carry that digest, so the inventory cannot drift from its source.
2. Deterministic extraction reads the modern packages map (or the classic nested dependencies map) and keeps only pinned components with versions, each with its evidence location inside the lockfile.
3. Licenses are normalized, counted, and risk-flagged: strong copyleft is high, weak copyleft is medium, missing license evidence is review. Risks are surfaced, never suppressed.
4. A lockfile that is not an object, carries no dependency map, or pins no components refuses with findings instead of emitting an empty inventory.

To inventory a remote lockfile, compose web-fetch for the governed read and pass its content here; the digest binds whatever bytes were supplied.

Output

sbom_result (runx.sbom.v1) carries decision (generated, refused), the CycloneDX 1.5 sbom or null, component_count, license_summary, license_risks, validation, and the lockfile digest.

Inputs are lockfile and optional lockfile_type (package-lock, npm-shrinkwrap).
