+# Binary Fingerprint Evidence Generation
+
+## Module
+Attestor
+
+## Status
+IMPLEMENTED
+
+## Description
+Extensive binary fingerprinting with disassembly, delta signatures, fingerprint indexing, and attestable proof generation covering ELF/PE analysis.
+
+## Implementation Details
+- **Evidence Generator**: `src/Attestor/__Libraries/StellaOps.Attestor.ProofChain/Generators/BinaryFingerprintEvidenceGenerator.cs` (with `.Helpers` partial) -- generates attestable proof segments from binary fingerprint analysis. Produces `BinaryFingerprintEvidencePredicate` payloads.
+- **Binary Identity**: `__Libraries/StellaOps.Attestor.ProofChain/Predicates/BinaryIdentityInfo.cs` -- binary identity (path, hash, format: ELF/PE/Mach-O, architecture).
+- **Vulnerability Matching**: `BinaryVulnMatchInfo.cs` -- links binary identity to CVE matches with confidence.
+- **Micro-Witness Evidence**: `MicroWitnessBinaryRef.cs`, `MicroWitnessFunctionEvidence.cs` -- function-level evidence linking fingerprints to reachability. `MicroWitnessTooling.cs` -- tool metadata.
+- **Binary Diff Integration**: `src/Attestor/__Libraries/StellaOps.Attestor.StandardPredicates/BinaryDiff/` -- `BinaryDiffPredicateBuilder.cs`, `BinaryDiffSectionModels.cs` handle section-level diffing for delta signature computation.
+- **Content-Addressed Storage**: fingerprint evidence is content-addressed via `ContentAddressedIdGenerator` from `__Libraries/StellaOps.Attestor.ProofChain/Identifiers/`.
+- **Note**: Actual binary disassembly and fingerprint indexing lives in `src/BinaryIndex/` module; Attestor provides the attestation layer wrapping those results.
+
+## E2E Test Plan
+- [ ] Generate fingerprint evidence from a binary analysis result containing ELF section hashes and verify `BinaryFingerprintEvidencePredicate` captures all section fingerprints
+- [ ] Generate fingerprint evidence from PE binary analysis and verify format-specific sections (.text, .rdata, .rsrc) are represented
+- [ ] Verify the evidence generator produces content-addressed IDs for each fingerprint evidence artifact
+- [ ] Create delta signatures by running the generator on two binary versions and verify the diff captures added/removed/changed sections
+- [ ] Verify `MicroWitnessFunctionEvidence` links specific functions to their fingerprint evidence
+- [ ] Run the generator twice on identical inputs and verify deterministic output (same evidence IDs)
+- [ ] Verify the generated evidence can be embedded in a DSSE-signed attestation via the proof chain signing infrastructure
