Now I have enough information to write the report.\n\n## Spec Adherence Report: Fix Multiple Entry Points Issue\n\n**Spec:** `docs/language_specification/program_entry_point.md`\n**Implementation:** `src/Sharpy.Compiler/CodeGen/RoslynEmitter.cs`, `src/Sharpy.Compiler/Project/ProjectCompiler.cs`\n\n### Spec Requirements Extracted\n\nFrom `program_entry_point.md`:\n1. \"The entry point is either a file with top-level statements or a `main()` function\"\n2. \"Top-level statements wrapped in generated `Main()` method\"\n3. \"Module code wrapped in `public static class Exports`\"\n4. \"The Python idiom `if __name__ == \"__main__\":` does not exist in Sharpy\"\n\n### Compliant\n\n- [x] **Top-level statements wrapped in Main()**: When `IsEntryPoint=true` and there are executable statements with no user-defined `main()`, the code generates a `Main()` method (RoslynEmitter.cs:453-473)\n- [x] **User-defined main() honored**: When a `main()` function exists, it is detected and processed (RoslynEmitter.cs:432-434)\n- [x] **Entry point file detection**: `ProjectCompiler.cs:406-420` correctly determines entry point based on `EntryPoint` config or defaults to `main.spy`\n- [x] **Non-entry-point files ignore executable statements**: Files not marked as entry points emit warnings and skip module-level executable code (RoslynEmitter.cs:482-486)\n- [x] **Module class naming**: Class names are derived from file names using PascalCase, with collision avoidance for \"Main\" class names (RoslynEmitter.cs:503-525)\n\n### Deviations\n\n- [ ] **POTENTIAL ISSUE - main() in non-entry-point files**\n  - **Spec says:** \"The entry point is either a file with top-level statements or a `main()` function\" (implies `main()` is special for entry points)\n  - **Implementation:** `GenerateFunctionDeclaration` at line 554 converts ALL functions named `main` to `Main` via `NameMangler.Transform()`, regardless of whether the file is the entry point. A `main()` function in a utility module would still become `Main()`.\n  - **Impact:** Medium - If a user defines `main()` in multiple files, this could cause \"multiple entry points\" errors at C# compilation, though this is arguably the correct behavior since the spec doesn't explicitly restrict where `main()` can be defined.\n\n- [ ] **Undocumented behavior - module-level statements with main()**\n  - **Spec says:** Silent on what happens when both top-level statements AND a `main()` function exist in the same file\n  - **Implementation:** RoslynEmitter.cs:475-480 ignores module-level statements when a `main()` function is defined, emitting a warning to Console\n  - **Impact:** Low - The behavior is reasonable (user-defined `main()` takes precedence), but undocumented in the spec\n\n- [ ] **Undocumented behavior - module-level statements in non-entry-point files**\n  - **Spec says:** Silent on what happens to top-level executable statements in imported modules\n  - **Implementation:** RoslynEmitter.cs:482-486 ignores them with a Console warning\n  - **Impact:** Low - The behavior is reasonable, but undocumented\n\n### Analysis of Multiple Entry Points Fix\n\nBased on the implementation:\n\n1. **Entry point determination** in `ProjectCompiler.cs` is correct:\n   - Uses `EntryPoint` from config if specified\n   - Defaults to `main.spy` if not specified\n   - Only ONE file gets `IsEntryPoint=true`\n\n2. **Main method generation** in `RoslynEmitter.cs`:\n   - Auto-generated `Main()` only created when: `!hasMainFunction && _context.IsEntryPoint && executableStatements.Count > 0`\n   - This correctly prevents auto-generated Main in non-entry-point files\n\n3. **User-defined main() handling**:\n   - `main()` \u2192 `Main()` via NameMangler regardless of file\n   - This is technically correct behavior since `main` is just a function name that happens to become `Main`\n   - The \"multiple entry points\" issue would only occur if multiple files define `main()` functions\n\n### Recommendations\n\n1. **Clarify spec** on whether `main()` function is only valid in the entry point file, or if it can exist in any file (with only the entry point file's `main()` being used as the program entry)\n\n2. **Consider semantic validation** to warn/error when:\n   - Multiple files define a `main()` function\n   - A non-entry-point file defines `main()` (which would become unreachable code)\n\n3. **Document behavior** for edge cases:\n   - Top-level statements + `main()` in same file\n   - Top-level statements in non-entry-point files (imported modules)\n\n4. **Replace Console.WriteLine warnings** with proper compiler warnings through the logging system so they appear in build output properly\n"

Assignments like `i = i + 1` are then treated as new declarations (`var i = i + 1;`) instead of assignments to existing fields.\n\n2. **Empty Module Entry Point**: The fix correctly changed `||` to `&&`, which means modules with no executable statements correctly don't generate Main. However, some tests expect empty/comment-only modules to compile as executables, which now fails with CS5001.\n\n### Root Cause Analysis\n\nThe 89 failing tests fall into these categories:\n\n| Category | Count | Error | Cause |\n|----------|-------|-------|-------|\n| No entry point | ~34 | CS5001 | Empty modules now correctly don't generate Main, but tests expected them to compile |\n| Variable shadowing | ~20 | CS0841/CS0844 | Module-level vars not tracked when processing Main body |\n| Module access | ~8 | CS0246 | Import/namespace resolution issues (unrelated) |\n| Class name collision | ~4 | CS0542 | Class named same as type (unrelated) |\n| Other | ~23 | Various | Mix of issues |\n\n### Recommendations\n\n1. **For the Entry Point Fix**: The code change is correct. Tests expecting empty modules to compile as executables should be updated to either:\n   - Add executable content (like `pass`)\n   - Compile as library instead of executable\n   - Use explicit `main()` function\n\n2. **For Variable Shadowing Bug**: This is a separate bug requiring a fix:\n   - Track module-level fields separately from local variables\n   - Before clearing `_variableVersions` for Main, preserve module-level field names\n   - When checking if a variable exists, also check if it's a module-level field\n\n3. **The fix should be applied** - it correctly addresses the multiple entry points issue. The failing tests reveal pre-existing issues that should be addressed separately.\n"

The `willHaveMainMethod` calculation starts at 489, but the method extends to line 526, not 525.\n\n---\n\n**Claim:** C# error CS0542 occurs when a class named \"Main\" contains a method named \"Main\"\n\n**Verification:** Created test C# file and compiled with `dotnet build`, got: `error CS0542: 'Main': member names cannot be the same as their enclosing type`\n\n**Result:** \u2705 CORRECT \u2014 Error code and behavior verified.\n\n---\n\n**Claim:** Solution uses \"Program\" as class name when class would be \"Main\" and Main method exists\n\n**Verification:** Read lines 514-517: `if (className == \"Main\" && willGenerateMainMethod) { return \"Program\"; }`\n\n**Result:** \u2705 CORRECT \u2014 Logic exactly as described.\n\n---\n\n**Claim:** All 385 CodeGen tests pass\n\n**Verification:** Ran `dotnet test --filter \"FullyQualifiedName~CodeGen\"` \u2014 Output: `Passed: 385`\n\n**Result:** \u2705 CORRECT \u2014 385 tests passing confirmed.\n\n---\n\n**Claim:** All 14 ProjectCompilation tests pass\n\n**Verification:** Ran `dotnet test --filter \"FullyQualifiedName~ProjectCompilationTests\"` \u2014 Output: `Passed: 14`\n\n**Result:** \u2705 CORRECT \u2014 14 tests passing confirmed.\n\n---\n\n**Claim:** Entry point determined by `ProjectConfig.EntryPoint` or defaults to `main.spy`\n\n**Verification:** Read `ProjectCompiler.cs` lines 406-420, which shows the logic defaults to files named \"main\" (checking without extension)\n\n**Result:** \u2705 CORRECT \u2014 The code checks `cfg.EntryPoint` first, then defaults to `main.spy` pattern.\n\n---\n\n**Claim:** Roslyn SyntaxFactory methods used: `MethodDeclaration`, `PredefinedType`, `Token`, `Block`, `ClassDeclaration`, `TokenList`\n\n**Verification:** Grep confirmed all these methods are present in the file\n\n**Result:** \u2705 CORRECT \u2014 All Roslyn methods exist and are used correctly.\n\n---\n\n**Claim:** Build succeeds with no errors\n\n**Verification:** Test runs executed successfully, implying build works. However full test suite shows 89 failures.\n\n**Result:** \u26a0\ufe0f MINOR_INCORRECT \u2014 While the build compiles and the specific CodeGen/ProjectCompilation tests pass, the full suite has 89 failing tests. The claim about \"Build succeeds\" is accurate, but \"All tests pass\" would be incorrect if applied to the full suite.\n\n---\n\n## Hallucination Summary\n\n- **Minor Issues:** 2 \n  - Line range for class collision fix is 489-526 not 489-525 (off by 1)\n  - Full test suite has 89 failures (though the specific test categories mentioned do pass)\n\n- **Major Issues:** 0\n\n- **Verdict:** **MINOR_ISSUES**\n\nAll technical claims about API behavior, Roslyn methods, C# error codes, and implementation logic are accurate. The only discrepancies are cosmetic (off-by-one line number) and a potential scope ambiguity about \"all tests pass\" (the specific categories mentioned do pass completely).\n"
