Replace character-by-character parsing with regex-based implementation
for value mapping and OR condition merging.
Changes:
- Add ApplyRegexMapping() for regex-based value replacement
* Uses VBScript.RegExp with Late Binding
* Replaces from back to front to avoid position shifts
* Uses regex.Replace() method for precise matching
* Includes EscapeForRegex() to handle special characters
- Add ProcessNestedExpressions() for recursive parenthesis handling
- Add MergeDuplicateORConditions() for OR deduplication
- Add SimplifyParentheses() for smart parenthesis removal
- Remove ProcessAndSimplifyNested() (150+ lines of complex logic)
- Remove ProcessAndSegment(), ProcessAtom(), ParseAtom()
- Remove MergeDuplicateORs(), MaybeRemoveOuterParentheses()
- Remove JoinCollection(), MergeDuplicateAtoms()
Regex patterns used:
- azxs: (azxs)( *=|!= *)([a-zA-Z0-9]{2})
- lcfw: (lcfw)( *=|!= *)([a-zA-Z]\d{1,3})(?=[ \(\)]?)
Processing flow:
1. Apply azxs value mapping (regex)
2. Apply lcfw value mapping (regex)
3. Process nested expressions (recursive OR merge)
4. Merge top-level OR conditions
5. Simplify unnecessary parentheses
Benefits:
- Code reduced from 647 to 553 lines (-15%)
- Core logic simplified significantly
- Better performance: single regex pass vs multiple string traversals
- Improved readability and maintainability
- Precise replacement using regex.Replace() instead of string Replace()
- Preserved late binding and backward compatibility

Add M05_PreProcessor module to handle value mapping and condition
simplification for "接头" category before parsing.
Features:
- Value mapping: azxs codes (A0/AT/AH→径向, B0/BT/BZ/BH→下轴向,
Z0/ZT/ZZ/ZH→中轴向) and lcfw ranges (M01-M11→低压, M12-M16→高压)
- OR condition merging: automatically removes duplicate OR segments
- Smart parentheses handling: removes parentheses for single atoms,
preserves them when needed for logical structure
- Recursive nested expression processing
- Graceful degradation when "对照表" worksheet is missing
Integration:
- Modified M01_Main to initialize preprocessor after M03_Logic
- Preprocessing applied only for "接头" category
- Updated M99_TestRunner with 8 comprehensive test cases
- All tests passing (50 total: 42 core + 8 preprocessing)
Documentation:
- Added detailed flow documentation for Test_PP_06_FullIntegration
with mermaid diagrams in docs/Test_PP_06_FullIntegration_流程详解.md
- Updated CLAUDE.md with preprocessing module description and
documentation guidelines (docs/ vs reference_docs/)
Example transformation:
Input: gclj=M16 AND (azxs=A0 OR azxs=AT) AND (lcfw=M01 OR lcfw=M15)
Output: gclj=M16 AND azxs=径向 AND (lcfw=低压 OR lcfw=高压)
