## 12. Binary Micro-Witnesses
Binary micro-witnesses provide cryptographic proof of patch status at the binary level. They formalize the output of BinaryIndex's semantic diffing capabilities into an auditor-friendly, portable format.
### 12.1 Overview
A micro-witness is a DSSE (Dead Simple Signing Envelope) predicate that captures:
- Subject binary digest (SHA-256)
- CVE/patch reference
- Function-level evidence with confidence scores
- Delta-Sig fingerprint hash
- Tool versions and analysis metadata
- Optional SBOM component mapping
### 12.2 Predicate Schema
**Predicate Type:** `https://stellaops.dev/predicates/binary-micro-witness@v1`
```json
{
"schemaVersion": "1.0.0",
"binary": {
"digest": "sha256:...",
"purl": "pkg:deb/debian/openssl@3.0.11",
"arch": "linux-amd64",
"filename": "libssl.so.3"
},
"cve": {
"id": "CVE-2024-0567",
"advisory": "https://...",
"patchCommit": "abc123"
},
"verdict": "patched",
"confidence": 0.95,
"evidence": [
{
"function": "SSL_CTX_new",
"state": "patched",
"score": 0.97,
"method": "semantic_ksg",
"hash": "sha256:..."
}
],
"deltaSigDigest": "sha256:...",
"sbomRef": {
"sbomDigest": "sha256:...",
"purl": "pkg:...",
"bomRef": "component-ref"
},
"tooling": {
"binaryIndexVersion": "2.1.0",
"lifter": "b2r2",
"matchAlgorithm": "semantic_ksg"
},
"computedAt": "2026-01-28T12:00:00Z"
}
```
### 12.3 Verdicts
| Verdict | Meaning |
|---------|---------|
| `patched` | Binary matches patched version signature |
| `vulnerable` | Binary matches vulnerable version signature |
| `inconclusive` | Unable to determine (insufficient evidence) |
| `partial` | Some functions patched, others not |
### 12.4 CLI Commands
```bash
# Generate a micro-witness
stella witness generate /path/to/binary --cve CVE-2024-0567 --sbom sbom.json --output witness.json
# Verify a micro-witness
stella witness verify witness.json --offline
# Create portable bundle for air-gapped verification
stella witness bundle witness.json --output ./audit-bundle
```
### 12.5 Integration with Rekor
When `--rekor` is specified during generation, witnesses are logged to the Rekor transparency log using v2 tile-based inclusion proofs. This provides tamper-evidence and enables auditors to verify witnesses weren't backdated.
Offline verification bundles include tile proofs for air-gapped environments.
