Phase 179-B Task 5: Refactor Pattern 2 to use PatternPipelineContext
for unified preprocessing.
Changes:
- Use build_pattern_context() for initial loop variable extraction and scope construction
- Extract loop_var_name, loop_var_id, carrier_info, and scope from context
- Keep Trim pattern logic inline (complex, needs dedicated module in future Phase 180+)
- Reduce line count: 517 → 509 lines (1.5% reduction)
Note:
Pattern 2 has significant complexity (Trim pattern, carrier filtering, break
condition processing) that cannot be easily unified without breaking the
"analyzer-only" design constraint of PatternPipelineContext. The minimal
refactoring maintains compatibility while establishing the pipeline pattern.
Benefits:
- Consistent entry point with Pattern 1/3
- Establishes pattern for future Trim module extraction
- Maintains all existing functionality and test compatibility
