# 1. Validate ISO 20022 pacs.008.001.10 (pip install pacs008)
pacs008 -t pacs.008.001.10 -m template.xml -s schema.xsd -d payments.csv --dry-run
✓ Schema validation passed
✓ Data validation passed (1 payment records)
# 2. Verify NIST FIPS 203 ML-KEM-768 KEM (cargo add kyberlib)
cargo test -p kyberlib --test test_kem
✓ test keypair_encap_decap ... ok
✓ test result: ok. 9 passed; 0 failed; finished in 0.01s
# 3. Verify live CycloneDX SBOM provenance (SLSA / Sigstore)
curl -sSLO https://sebastienrousseau.com/sbom.cdx.json && gh attestation verify sbom.cdx.json --owner sebastienrousseau
✓ Loaded 1 attestation from GitHub API (slsa.dev/provenance/v1)
✓ Verification succeeded!What I build
