❌ This issue is not open for contribution. Visit Contributing guidelines to learn about the contributing process and how to find suitable issues.

Overview

Final cleanup tasks after all 5 module migrations are complete. This issue removes the legacy resources/ directory and updates configuration files.

Prerequisites

Blocked by: #182, #183, #184, #185, #186

All 5 module migrations must be completed before this cleanup can proceed.

Tasks

1. Remove package_data from setup.py

   • Remove the line: package_data={"le_utils": ["resources/*.json"]}
   • The resources directory will no longer exist, so this must be removed

2. Delete le_utils/resources/ directory

   • Verify all JSON files have been deleted by individual migration issues
   • Remove the empty resources/ directory itself

3. Update README.md

   • Remove warnings about keeping Python/JSON in sync
   • Update documentation to describe spec + generation workflow
   • Remove references to manual constants maintenance

4. Update CHANGELOG.md

   • Add entry for the migration with version number
   • List all migrated modules
   • Note JavaScript exports now available for all constants

5. Verify entire test suite passes

   • Run pytest tests/ -v
   • Ensure no broken imports or references to old JSON files

How to Verify

# Ensure resources directory doesn't exist
ls le_utils/resources/  # should error: No such file or directory

# Verify tests pass
pytest tests/ -v

# Verify build works
make build

# Verify package can be installed
python setup.py sdist
pip install dist/le-utils-*.tar.gz

Acceptance Criteria

• package_data removed from setup.py
• le_utils/resources/ directory deleted
• README.md updated to remove sync warnings
• README.md updated to document spec + generation workflow
• CHANGELOG.md updated with migration notes
• All tests pass: pytest tests/ -v
• make build succeeds
• Package builds and installs successfully

After issues #182–#186 are complete, inspect package_data in setup.py and verify the le_utils/resources/ directory is gone. Update README.md and CHANGELOG.md as specified, then run pytest tests/ -v, make build, and the package build/install commands; done means all listed acceptance criteria pass.
