ci: strip notebook outputs via git filter instead of pre-commit hook#9
Merged
Conversation
Replaces the in-place nbstripout pre-commit hook (which stripped the working copy on every commit) with the nbstripout git *filter*: outputs are stripped from the committed blob while staying in the working tree, so notebooks stay rendered locally. Set up per clone via the bundled `install-hooks` task; enforced in CI with `nbstripout --verify`. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

What
Switches notebook-output stripping from the in-place
nbstripoutpre-commit hook to the nbstripout git filter.Why
The pre-commit hook rewrote the notebook on disk at every commit, so working-copy outputs were destroyed and had to be re-run. The git filter strips outputs only from the committed blob and leaves the working tree untouched — notebooks stay rendered locally, git history stays clean.
