SHEET 03SUPPLY CHAIN · SBOM · EU CRA ANNEX I

A CVE is a query,
not a war room.

Supplier SBOMs land on the architecture, not in a folder. When a CVE publishes, the route — component → software unit → ECU → project → vehicle — is already wired. You answer in minutes, with the evidence chain attached.

STATION 1 · INGEST

SBOMs as delivered.
Diffed, not overwritten.

CycloneDX and SPDX per software unit, versioned per baseline. Re-imports diff against the last delivery — 12 new components is a changelog entry, not a mystery.

STATION 2 · MATCH

Watched continuously.
Triaged by position.

Components are matched against vulnerability feeds around the clock. Priority comes from where a component sits in the architecture — not CVSS alone.

STATION 3 · ROUTE

CVE → component →
ECU → vehicle. One query.

The match lands on the graph, so blast radius is computed: which software units, which projects, which programs. Suppliers get a share request, not an email thread.

TRACE → unit · ECU · project · program
NOTIFY → supplier workspace share
RE-OPEN → affected risks · TARA lines
VEX: affected / not affected ← OUTPUT
justification attached ← EVIDENCE
EU CRA Annex I disclosures ← READY
STATION 4 · DISCLOSE

VEX with the proof
built in.

Not-affected statements carry their justification from the graph. We publish our own platform SBOM the same way — see the Trust Center.
