Golden File Generation - Final Status
=======================================

COMPLETED: 3/7 files successfully generated
BLOCKED: 4/7 files blocked on transpiler bugs

✅ SUCCESSFULLY GENERATED (3 files):
1. pattern_match_09_tuple_pairs.go.golden (1502 bytes) - ✅ Tests PASS
2. pattern_match_10_tuple_triples.go.golden (1743 bytes) - ✅ Tests PASS
3. pattern_match_11_tuple_wildcards.go.golden (1828 bytes) - ⚠️ Non-deterministic (see below)

❌ BLOCKED ON TRANSPILER BUGS (4 files):
1. pattern_match_01_simple.dingo
   - Error: Line 103: expected operand, found ','
   - Cause: Preprocessor generates invalid Go syntax for basic match expressions

2. pattern_match_03_nested.dingo
   - Error: Line 62: missing ',' in argument list (5+ errors)
   - Cause: Nested match expression transformation bug

3. pattern_match_06_guards_nested.dingo
   - Error: Line 93: missing ',' in argument list (10+ errors)
   - Cause: Guard condition handling in preprocessor

4. pattern_match_12_tuple_exhaustiveness.dingo
   - Error: Line 149: no pattern arms found
   - Cause: Pattern arm parsing fails in preprocessor

⚠️ CRITICAL ISSUE DISCOVERED: Non-Deterministic Output
========================================================

The pattern match plugin generates DIFFERENT code on each transpilation run.
Specifically, the ordering of switch case statements changes randomly.

**Evidence**:
- File pattern_match_11_tuple_wildcards.dingo transpiles successfully
- Output compiles successfully
- Golden test FAILS because output differs from previous run
- Re-running transpiler produces different switch case order

**Impact**:
- Golden tests are unreliable (fail even when code is correct)
- Cannot guarantee idempotent transpilation
- Debugging is difficult (can't reproduce exact output)

**Root Cause**:
The PatternMatchPlugin likely uses Go map iteration (which is randomized)
to generate switch cases, causing non-deterministic ordering.

**Required Fix**:
1. Ensure pattern match plugin generates deterministic output
2. Sort switch cases consistently (by tag value or pattern order)
3. Regenerate all pattern match golden files after fix

TEST RESULTS:
=============

Compilation Tests: ✅ 3/3 PASS
- All 3 generated files compile successfully
- No Go syntax errors
- Type checking passes

Golden Diff Tests: ⚠️ 2/3 PASS (non-determinism)
- pattern_match_09_tuple_pairs: ✅ PASS (sometimes)
- pattern_match_10_tuple_triples: ✅ PASS (sometimes)
- pattern_match_11_tuple_wildcards: ❌ FAIL (non-deterministic)

SUMMARY:
========

**Immediate Deliverables**: 3 golden files created (42.9% success rate)

**Blocking Issues**:
1. Preprocessor bugs preventing 4 files from transpiling (57.1% failure rate)
2. Non-deterministic output making golden tests unreliable

**Next Steps**:
1. Fix non-determinism in PatternMatchPlugin (CRITICAL)
2. Fix rust_match preprocessor bugs (4 failing files)
3. Regenerate all 7 golden files with fixed transpiler
4. Verify 14/14 pattern match tests pass consistently
