### ✅ Offset Preservation
Every binary field retains its original offset for complete traceability.

### ✅ State Distinction
Clear separation between RAW, DECODED, NORMALIZED, and SEMANTIC states.

### ✅ Provenance Tracking
Every artifact is hashed and traceable through the complete pipeline.

### ✅ Fail-Closed Design
Unknown structures produce errors, never guesses.

### ✅ Version Awareness
BEAM format versions are explicitly handled.

### ✅ Deterministic Results
Same inputs always produce same outputs.

### ✅ Safety First
Parsing never requires execution; sandboxed execution is optional.
