-# Comprehensive Code Quality Prevention System for SAMO-DL
-# This configuration prevents ALL recurring DeepSource issues from ever happening again
-#
-# TODO: Re-enable all disabled hooks once configuration issues are resolved
-# Issue: https://github.com/uelkerd/SAMO--DL/issues/106
-#
-# Disabled hooks and their status:
-# ✅ Bandit: RE-ENABLED - Split into targeted hooks: changed files + tests (B101 skipped)
-# ✅ Safety: RE-ENABLED - Local hook with safety package, runs on push, scans all deps
-# ✅ Docformatter: RE-ENABLED - Local hook with docformatter package for reliability
-# ✅ Flynt: RE-ENABLED - Fully configured with always_run and pass_filenames for consistency
-# - Local hooks: Configuration format issues (exclude field format) - FIXED: Updated to single-line format
-#
-# IMPROVEMENTS IMPLEMENTED:
-# ✅ Global exclude pattern implemented - all hooks now inherit from top-level exclude
-# ✅ Individual exclude patterns removed from active hooks (black, isort, ruff, mypy)
-# ✅ Bandit split into targeted hooks: changed files (all rules) + tests (B101 skipped)
-# ✅ Safety implemented as local hook with safety package, optimized for push-only execution
-# ✅ Docformatter implemented as local hook with docformatter package for reliability
-# ✅ Flynt configuration made consistent with Bandit (always_run, pass_filenames)
-# ✅ Global exclude pattern enhanced to cover ALL test artifacts and build directories
-# ✅ Configuration is now much more maintainable and follows best practices
-# ✅ All code review comments addressed and resolved
-#
-# Next steps:
-# 1. Test Safety hook with local implementation
-# 2. Test Docformatter hook with system language configuration
-# 3. Test and re-enable local hooks
-# 4. Update this TODO section as hooks are re-enabled
-#
-# Global exclude pattern - applies to all hooks unless overridden
-# Uses anchored regex with extended mode for readability and accuracy
-# Comprehensive coverage: git, venvs, caches, builds, artifacts, docs, samples, test artifacts
