📝 Walkthrough

Walkthrough

The notebooks/2-hpc-cluster.ipynb notebook has its per-cell trusted flags changed from false to true for code cells. The top-level kernelspec and language_info metadata is expanded with additional fields such as display name, codemirror mode, lexer, and version details. No cell source content, outputs, or execution counts are modified.

Poem

🐇 A notebook once doubted itself, so I heard,
Its "trusted: false" a most dubious word.
With a hop and a flip, I set it to true,
And sprinkled some kernelspec fields, shiny and new!
Now the cells run with confidence, proud as can be —
Trust yourself, little notebook, just like me! ✨

In `@notebooks/2-hpc-cluster.ipynb`:
- Line 1: The notebook file "notebooks/2-hpc-cluster.ipynb" has an inconsistency
where all code cells are marked as `trusted: true` but only 5 of 9 cells have
execution metadata (execution_count) and only 3 of 9 have captured outputs,
indicating the notebook was only partially executed before commit. Either fully
execute all code cells in the notebook and save the outputs to match the trusted
state, or remove the `trusted: true` flag from all code cells that have not been
executed and saved with outputs to ensure consistency between the trusted
metadata and the actual execution state.
