GOLDEN TEST RESULTS - Phase 1 (Preprocessor Integration)
=========================================================

Test Command: go test ./tests -run TestGoldenFiles/error_prop_XX -v

TEST 1: error_prop_01_simple
----------------------------
Status: PARSE SUCCESS ✅
Parsing: No errors (preprocessor → parser pipeline works)
Output: Fails on comparison (extra blank lines, same logic)

Differences:
- Extra blank lines before/after dingo markers
- Otherwise identical output

TEST 2: error_prop_03_expression
---------------------------------
Status: PARSE SUCCESS ✅
Parsing: No errors (preprocessor → parser pipeline works)
Output: Fails on comparison (variable numbering + blank lines)

Differences:
- Error variable: __err1 instead of __err0 (counter mismatch)
- Extra blank lines before/after dingo markers
- Logic is correct

TEST 3: error_prop_06_mixed_context
------------------------------------
Status: PARSE SUCCESS ✅
Parsing: No errors (preprocessor → parser pipeline works)
Output: Fails on comparison (variable numbering + blank lines)

Differences:
- Error variable: __err2 instead of __err1 (counter mismatch)
- Extra blank lines before/after dingo markers
- Logic is correct

SUMMARY
=======
✅ All 3 tests now PARSE successfully (no parser errors)
❌ Tests fail on output comparison (formatting differences only)

Root Cause of Comparison Failures:
1. Extra blank lines: Preprocessor or generator adds extra newlines
2. Variable numbering: Error counter logic differs between CLI and test path

Next Steps:
- Phase 2: Fix blank line insertion
- Phase 3: Align error variable counter logic
