Pipeline Internals

Scan Sequence
-------------

1. Resolve target (binary vs source, language detection)
2. Load MemHint summaries if available
3. Validate tool availability
4. Execute tools in parallel (asyncio)
5. Parse outputs → MemoryError objects
6. Deduplicate across tools
7. AI 4-pass analysis with MemHint context
8. Fix validation (pattern + CWE + Z3)
9. Post-processing (CVE, relationships, hardening)
10. Cache and present
