+# Binary Test Fixtures
+
+This directory contains metadata and references to binary test fixtures used for golden set diff validation.
+
+## Structure
+
+```
+binaries/
+├── openssl/         # OpenSSL library binaries
+│   └── manifest.json
+├── glibc/           # GNU C Library binaries
+│   └── manifest.json
+├── synthetic/       # Minimal test binaries
+│   └── manifest.json
+└── README.md
+```
+
+## Binary Acquisition
+
+Actual binary files are not stored in git due to size constraints. During test execution:
+
+1. **CI Environment**: Binaries are downloaded from the StellaOps artifact store
+2. **Local Development**: Use `stella test fixtures download` to fetch binaries
+3. **Air-gapped**: Pre-populate from offline bundle
+
+## Manifest Format
+
+Each component directory contains a `manifest.json` with:
+
+- Version metadata (vulnerable vs patched)
+- Build information (compiler, flags, platform)
+- File digests (SHA-256)
+- CVE applicability mapping
+
+## Creating New Fixtures
+
+1. Add version entry to appropriate manifest
+2. Build binary with debug symbols (`-g` flag)
+3. Upload to artifact store with computed digest
+4. Update test pairs for fix verification tests
+
+## Synthetic Fixtures
+
+The `synthetic/` directory contains minimal C programs designed to test specific vulnerability patterns:
+
+- `vuln-simple.c` - Direct buffer overflow
+- `vuln-gated.c` - Vulnerability with validation that can be bypassed
+- `vuln-multi.c` - Multiple vulnerable functions with shared sink
+
+These can be recompiled locally using the provided source files.
