Replace 'str | None' with 'Optional[str]' in validate_citations.py
for compatibility with Python 3.9 and earlier versions used in
pre-commit environments.
Add missing citations to chapter bib files:
- carlini2021extracting to privacy_security.bib
- koomey2011web to frontiers.bib
- quinonero2009dataset to robust_ai.bib
Enhance citation validation script:
- Strip trailing punctuation (.,;:) from citation keys
- Filter out DOI-style citations (e.g., @10.1109/...)
- Prevent false positives from citations like [@key.]
These changes fix all reported citation validation failures while
improving the validation script to handle edge cases better.
Add new pre-commit hook to validate that all @key citations in .qmd
files have corresponding entries in their .bib files. This catches
missing bibliography entries before they cause Quarto build failures.
Features:
- Validates citations against bibliography files
- Filters out cross-reference labels (fig-, tbl-, sec-, etc.)
- Provides clear error messages with missing citation keys
- Only checks files being committed (not entire codebase)
- Runs in quiet mode to reduce noise
New script: tools/scripts/content/validate_citations.py
Updated: .pre-commit-config.yaml with validate-citations hook
