# SupplyChainBench (datasets/004-supply-chain) — CycloneDX clinical-agent profile

Paper 004's labeled AIBOM corpus. Apache-2.0, fully synthetic.

## Layout
- `manifests/clean.json` — a clean CycloneDX 1.5 AIBOM (gen.py, seed 42). **Generated, gitignored.**
- `attacks/<class>-<j>.json` — tampered AIBOMs, one per S-class. **Generated, gitignored.**
- `labels.json` — ground truth `{file, class, where}`. **Generated, gitignored.**
- This file + `scripts/004-supply-chain/{gen.py,osv_snapshot.json}` are the committed artifacts.

## CycloneDX clinical-agent profile
Standard CycloneDX 1.5 with `metadata.properties[quokkaguard:profile] = "clinical-agent"`
and per-component `properties`: `quokkaguard:class` ∈
{rule, chain, config, model, library, provider, mcp, data} and
`quokkaguard:attested` ∈ {true,false}. File-backed components carry a
`hashes[].content` SHA-256; library components use the registry checksum; provider
(weights) and forward-looking mcp/data components are unattested — the measured
provenance gap.

## Attack classes
| class | mutation | detected by |
|---|---|---|
| s1_weight_tamper | detector model digest altered | digest mismatch (verify) |
| s2_dependency_cve | a library pinned to a version in osv_snapshot.json | OSV scan |
| s3_typosquat | a library renamed to a look-alike | identity/digest pin |
| s4_provenance_gap | a component stripped of its attestation | provenance-gap count / required-attestation gate |
| s5_data_tamper | a rule/reference digest altered | digest mismatch |
