Layer 1: Pre-commit hook (scripts/check_no_binaries.sh) blocks 60+
binary/image extensions with .binary-allowlist for build-essential exceptions.
Layer 2: Comprehensive .gitignore binary patterns with ! overrides
for allowlisted files (app icons).
Layer 3: Agent exclusions - .copilotignore, files.exclude, and
search.exclude all mirror the same patterns to prevent Copilot
from hitting the 20-image URL limit.
- git rm 146 tracked PNG images from praca_magisterska_video/images/
- git rm 1 tracked .apkg from anki_decks/warsaw_districts/
- Add *.apkg and praca_magisterska_video/images/ to .gitignore
- Update .copilotignore with ** recursive patterns for all binary types
- Add files.exclude and search.exclude in .vscode/settings.json
- All binary files preserved in ../testsAndMisc_binaries/
- Add +x to Python scripts with shebangs (3 files)
- Remove -x from non-script files like .cpp, .txt, makefile (23 files)
