Add comprehensive tests for Go and Python version conflict detection and licensing normalization

Browse Source 
- Implemented GoVersionConflictDetectorTests to validate pseudo-version detection, conflict analysis, and conflict retrieval for Go modules.
- Created VersionConflictDetectorTests for Python to assess conflict detection across various version scenarios, including major, minor, and patch differences.
- Added SpdxLicenseNormalizerTests to ensure accurate normalization of SPDX license strings and classifiers.
- Developed VendoredPackageDetectorTests to identify vendored packages and extract embedded packages from Python packages, including handling of vendor directories and known vendored packages.

# Sprint 0134 · Native Analyzer Bug Fixes
## Topic & Scope
- Bug fixes and feature completion for native binary analyzers (ELF, PE, Mach-O)
- Address critical bugs discovered in code review: PE 64-bit parsing, PE resource extraction, ELF version needs
- Bring ELF/PE analyzers to feature parity with Mach-O analyzer
- **Working directory:** `src/Scanner/StellaOps.Scanner.Analyzers.Native` (and this tracking file under `docs/implplan`)
## Dependencies & Concurrency
- Upstream: Sprint 0132 · Scanner & Surface (native analyzers implemented but with bugs)
- Tasks 1-3 are independent bug fixes and can proceed in parallel
- Tasks 4-6 are tests that depend on their respective bug fixes
- Task 7 is a feature addition that can proceed independently
## Documentation Prerequisites
- docs/README.md
- docs/07_HIGH_LEVEL_ARCHITECTURE.md
- docs/modules/scanner/architecture.md
- src/Scanner/AGENTS.md
## Problem Summary
### PE Analyzer Bugs (PeImportParser.cs)
1. **Line 234**: `is64Bit: false` hardcoded in `ParseImportDirectory` - breaks 64-bit PE import parsing
2. **Lines 462-473**: `ParseSectionHeaders(span, 0, 0)` returns empty list - resource manifest always falls back to text search
### ELF Analyzer Gap (ElfDynamicSectionParser.cs)
1. **Lines 374-395**: `ParseVersionNeeds` returns empty dictionary - GLIBC version requirements never extracted
### Reference Implementation
- Mach-O analyzer is feature-complete with weak/reexport/lazy classification, version parsing, and comprehensive tests
## Delivery Tracker
| # | Task ID | Status | Key dependency / next step | Task Definition |
|---|---------|--------|----------------------------|-----------------|
| 1 | NATIVE-FIX-PE-64BIT | TODO | None | Fix PE import parser 64-bit thunk parsing. Thread `is64Bit` through `ParseImportDirectory` method signature or refactor to capture in parser state. Location: `PeImportParser.cs:234` |
| 2 | NATIVE-FIX-PE-RESOURCE | TODO | None | Fix PE resource manifest extraction. Pass `List<SectionInfo> sections` to `FindFirstResourceData`, use proper RVA-to-file-offset conversion instead of text search fallback. Location: `PeImportParser.cs:462-473` |
| 3 | NATIVE-FIX-ELF-VERNEED | TODO | None | Implement ELF version needs parsing. Parse section headers to find `.gnu.version_r` section, parse `Elf64_Verneed` (16 bytes) and `Elf64_Vernaux` (16 bytes) structures, map version requirements to parent library. Location: `ElfDynamicSectionParser.cs:374-395` |
| 4 | NATIVE-TEST-PE-64BIT | TODO | NATIVE-FIX-PE-64BIT | Add PE 64-bit import parsing test to `PeImportParserTests.cs`. Create synthetic PE32+ binary with import table, verify correct thunk parsing (8-byte entries). |
| 5 | NATIVE-TEST-PE-MANIFEST | TODO | NATIVE-FIX-PE-RESOURCE | Add PE proper resource manifest test to `PeImportParserTests.cs`. Create synthetic PE with embedded RT_MANIFEST resource, verify extraction via resource directory (not text search). |
| 6 | NATIVE-TEST-ELF-VERNEED | TODO | NATIVE-FIX-ELF-VERNEED | Add ELF version needs parsing test to `ElfDynamicSectionParserTests.cs`. Create synthetic ELF with `.gnu.version_r` section containing GLIBC_2.17 requirement, verify extraction. |
| 7 | NATIVE-FEATURE-ELF-WEAK | TODO | None | Add ELF weak symbol detection for parity with Mach-O. Parse symbol table for STB_WEAK binding, emit separate reason code for weak dependencies. |
## Technical Details
### ELF Verneed Structure (Elf64_Verneed - 16 bytes)
```
vn_version (2 bytes) - version of structure (should be 1)
vn_cnt (2 bytes) - number of Vernaux entries
vn_file (4 bytes) - offset to filename in strtab
vn_aux (4 bytes) - offset to first Vernaux entry
vn_next (4 bytes) - offset to next Verneed entry (0 if last)
```
### ELF Vernaux Structure (Elf64_Vernaux - 16 bytes)
```
vna_hash (4 bytes) - hash of version name
vna_flags (2 bytes) - flags (VER_FLG_WEAK = 0x2)
vna_other (2 bytes) - version index
vna_name (4 bytes) - offset to version string in strtab
vna_next (4 bytes) - offset to next Vernaux entry (0 if last)
```
### PE Import Thunk Size
- PE32 (32-bit): 4 bytes per thunk entry
- PE32+ (64-bit): 8 bytes per thunk entry
- Current code hardcodes 4 bytes, breaking 64-bit PE parsing
## Execution Log
| Date (UTC) | Update | Owner |
|------------|--------|-------|
| 2025-12-07 | Sprint created based on code review of native analyzers; identified 2 PE bugs and 1 ELF placeholder | Implementer |
## Decisions & Risks
- PE resource parsing fix may require broader refactoring if section headers aren't available in the right scope
- ELF version needs parsing adds complexity; consider performance impact on large binaries
- Mach-O analyzer is the reference implementation for feature parity goals
## Estimated Effort
| Task | Effort | Risk |
|------|--------|------|
| PE bitness fix | 30 min | Low |
| PE resource parsing fix | 2-4 hours | Medium |
| PE tests | 1 hour | Low |
| ELF version needs impl | 4-8 hours | Medium |
| ELF weak symbol detection | 2-4 hours | Low |
| ELF tests | 2 hours | Low |
**Total: 1-2 days for critical fixes, 3-4 days for complete feature parity with Mach-O**

## Decisions & Risks
- **Progress (2025-12-05):** Graph (0140.A) DONE; Zastava schemas/thresholds/kit DSSE-signed on 2025-12-02 (keyid mpIEbYRL1q5yhN6wBRvkZ_0xXz3QUJPueJJ8sn__GGc) with artefacts staged under `docs/modules/zastava/kit` and `evidence-locker/zastava/2025-12-02/`; deterministic tar rebuilt with payloads (`evidence-locker/zastava/2025-12-02/zastava-evidence.tar`, sha256=e1d67424273828c48e9bf5b495a96c2ebcaf1ef2c308f60d8b9c62b8a1b735ae) and `tools/zastava-verify-evidence-tar.sh` passing (hash + inner SHA). Signals wave (0140.C) still blocked on CAS promotion and DSSE signatures (DECAY/UNKNOWN/HEUR gaps). AirGap staleness (0120.A 56-002/57/58) and Scanner Java/Lang chain (0131 21-005..011) remain blockers, keeping all 150.* tasks BLOCKED.
- **Progress (2025-12-06):** Graph (0140.A) ✅ DONE; Zastava (0140.D) ✅ DONE; AirGap staleness (0120.A 56-002/57/58) ✅ DONE with schema at `docs/schemas/ledger-airgap-staleness.schema.json`; Signals (0140.C) ✅ UNBLOCKED. **Only remaining blocker:** Scanner surface Java/Lang chain (0131 21-005..011) blocked on CoreLinksets. Once Java analyzer tasks clear, 150.A-Orchestrator can enter DOING.
- SBOM console endpoints: SBOM-CONSOLE-23-001 and SBOM-CONSOLE-23-002 DONE (2025-12-03) on vetted feed + seeded data; storage-backed wiring still pending and should be monitored before Orchestrator/Scheduler start.
- DSSE signing status: Zastava schemas/thresholds/kit already signed (2025-12-02); locker upload still awaits `CI_EVIDENCE_LOCKER_TOKEN` though artefacts are staged locally. Signals (0140.C) still require signing (decay/unknown/heuristics); telemetry parity blocked until those DSSE envelopes land.
- Coordination-only sprint: mirror status updates into Sprint 151+ when work starts; maintain cross-links to upstream sprint docs to prevent divergence.
