Risk: future CycloneDX/SPDX spec versions may add new volatile fields. Mitigation: versioned contract file allows controlled expansion. +- **Normalizer placement:** `SbomNormalizer` currently lives in `AirGap.Importer`.

Decision deferred — if multiple modules need it, extract to `StellaOps.Canonical.Sbom` shared lib in a follow-up. +- **Media type naming:** Using `application/vnd.stellaops.sbom.cdx+json` and `application/vnd.stellaops.sbom.spdx+json` for published artifacts.
