# Sprint: SPRINT_8200_0001_0003 - SBOM Schema Validation in CI
|
||||
# Task: SCHEMA-8200-004 - Create validate-sbom.sh wrapper for sbom-utility
|
||||
#
|
||||
# Validates SBOM files against official CycloneDX JSON schemas.
|
||||
# Uses sbom-utility for CycloneDX validation.
|
||||
#
|
||||
# Usage:
|
||||
# ./scripts/validate-sbom.sh <sbom-file> [--schema <schema-path>]
|
||||
# ./scripts/validate-sbom.sh bench/golden-corpus/sample.cyclonedx.json
|
||||
# ./scripts/validate-sbom.sh --all # Validate all CycloneDX fixtures
|
||||
#
|
||||
# Exit codes:
|
||||
# 0 - All validations passed
|
||||
# 1 - Validation failed or error
