+
+## ✅ FIXED - Ready to Close (7 issues)
+
+### #44 - clang-format stops working when using --version
+**Status**: ✅ FIXED
+**Fix**: Improved version argument parsing in parse_args()
+**Files Modified**: `hooks/utils.py`
+**Test Coverage**: Added version parsing edge case tests
+**Action**: Test with issue config and close
+
+---
+
+### #46 - Class ClangTidyCmd disregards its `args` parameter
+**Status**: ✅ FIXED
+**Fix**: Fixed critical logic error in clang-tidy --fix-errors handling
+**Files Modified**: `hooks/clang_tidy.py:27`
+**Issue**: `if len(self.stderr) > 0 and "--fix-errors" in self.args:` (WRONG - inverted logic)
+**Fixed**: `if len(self.stderr) > 0 and "--fix-errors" not in self.args:` (CORRECT)
+**Test Coverage**: Regression tests in test_logic_regression.py
+**Commit**: fd3ea4a
+**Action**: Close with reference to commit
+
+---
+
+### #49 - Incorrect order of arguments for include-what-you-use
+**Status**: ✅ FIXED
+**Fix**: Corrected argument order to match IWYU specification
+**Files Modified**: `hooks/include_what_you_use.py:25`
+**Before**: `self.run_command([filename] + self.args)`
+**After**: `self.run_command(self.args + [filename])`
+**Reason**: IWYU expects `<clang opts> <source file>` not `<source file> <clang opts>`
+**Action**: Close with this fix
+
+---
+
+### #55 - include-what-you-use does not fail
+**Status**: ✅ FIXED
+**Fix**: Improved error detection to force failure when includes are incorrect
+**Files Modified**: `hooks/include_what_you_use.py`

+2. Added explicit returncode=1 when includes are incorrect but IWYU doesn't fail properly
+**Action**: Close - related to #49, both fixed together
+
+---
+
+### #61 - Mistake in comment ?
+**Status**: ✅ FIXED
+**Fix**: Fixed misleading comment about --fix-errors behavior
+**Files Modified**: `hooks/clang_tidy.py:22`
+**Also Fixed**: The actual logic error the comment described
+**Test Coverage**: Regression tests validate fix
+**Commit**: fd3ea4a
+**Action**: Close with commit reference
+
+---
+
+### #66 - Bump black from 19.10b0 to 24.3.0

+**Files Modified**: `README.md`
+**Added**: Instructions to add `/opt/homebrew/opt/llvm/bin` to PATH
+**Note**: Clarified that llvm includes the tools but PATH setup may be needed
+**Action**: Close with documentation update reference
+
+---
+
+## 🔧 IMPROVED (3 issues)
+
+### #45 - oclint multiple execution and inability to see the output
+**Status**: 🔧 IMPROVED
+**Improvements Made**:
+1. Added progress indicator showing "Analyzing file X/N"
+2. Added comment explaining per-file execution is by design
+**Files Modified**: `hooks/oclint.py`
+**Remaining**: This is partly by design (per-file analysis)
+**Action**: Comment explaining the fix, ask for feedback on remaining concerns
+
+---
+
+### #64 - Exit cpplint only after checking all files
+**Status**: 🔧 RELATED TO #45
+**Note**: Similar to OCLint per-file execution
+**Current Behavior**: Exits on first error (exit_on_error called per file)
+**Action**: Investigate if this needs changing - may be by design
+
+---
+
+### #51 - clang-tidy file exclude pattern ignored
+**Status**: ❓ NEEDS MORE INFO (but may work now)
+**Possible Fix**: Our clang-tidy args handling fix may have resolved this
+**Action**: Request example config and test with latest changes
+
+---
+
+## ❓ NEED MORE INFORMATION (4 issues)
+
+### #58 - clang-tidy: for the -p option: may not occur within a group!
+**Status**: ❓ NEED MORE INFO
+**Issue**: Using `-p some/folder` gives grouping error
+**Possible Causes**:
+1. How pre-commit passes args to hooks
+2. Clang-tidy version differences
+3. Our args parsing
+**Action**: Request:
+- Full error output
+- clang-tidy version
+- Complete `.pre-commit-config.yaml`
+- Expected vs actual behavior
+
+---
+
+### #62 - file not found [clang-diagnostic-error] #include "lib1.h"
+**Status**: ❓ USER CONFIGURATION
+**Issue**: Include files not found during linting
+**Likely Cause**: Missing compilation database or incorrect include paths
+**Not a Bug**: This is expected when compilation database is missing/incomplete
+**Action**: Add better documentation about:
+1. Requiring compilation database for includes
+2. How to generate with cmake
+3. How to specify include paths
+
+---
+
+### #59 - Use a clang-format file that isn't at the root
+**Status**: 🎯 FEATURE REQUEST
+**Effort**: Medium
+**Current**: clang-format looks in current directory
+**Requested**: Support `--style=file:/path/to/.clang-format`
+**Action**: Label as enhancement, defer to future
+
+---
+
+### #57 - Configurable uncrustify executable path
+**Status**: 🎯 FEATURE REQUEST
+**Effort**: Medium
+**Current**: Hardcoded as "uncrustify"
+**Requested**: Support custom paths
+**Workaround**: Modify PATH environment
+**Action**: Label as enhancement, defer to future
+
+---
+
+## 🎯 FEATURE REQUESTS - Defer (3 issues)
+
+### #38 - Add ability to only lint/analyze committed lines
+**Priority**: Medium (oldest: 4+ years)
+**Effort**: High
+**Action**: Defer - complex feature
+
+### #67 - Example hook config for vala
+**Priority**: Low
+**Effort**: Very Low
+**Action**: Could add example to README easily
