Thanks @ramashishmaurya — the bedrock type hints are welcome. One thing to fix: this PR also touches .github/workflows/publish.yml, but the change is a no-op (the pypa/gh-action-pypi-publish@release/v1 line is byte-identical — looks like a whitespace/line-ending edit). That accidental workflow-file change means the PR now requires workflow OAuth scope to merge (which automation lacks). Please revert publish.yml (e.g. git checkout origin/development -- .github/workflows/publish.yml) so the PR is just the bedrock.py + eval/chart.py type hints — then it can merge normally. Thanks!
