## Changes - Added ipykernel to dev dependencies in default template's pyproject.toml - Fixed outdated comment in conftest.py (removed reference to 'tests under resources/') - Updated acceptance test outputs for default-python, lakeflow-pipelines, and pydabs templates ## Why ipykernel enables Jupyter notebook support with the project's virtual environment, which is essential for the exploratory notebooks included in the template. The conftest comment was outdated and misleading. ## Investigation Confirmed that databricks.sdk.runtime.spark already works correctly in the template: - Unit tests properly use databricks.sdk.runtime.spark - pytest --collect-only is fast (~0.05s) and doesn't eagerly connect - DBR 15+ compatibility works via validateSession() - The eager initialization in conftest.py serves real purposes (compute config, version validation) and should be kept ## Tests - All template acceptance tests pass - Verified pytest --collect-only behavior - Tested on Python 3.9-3.13 - Tested with both classic and serverless compute

Changes
This adds ipykernel to the
defaulttemplate and derived templates, which makes DB Connect notebooks work out of the box in Cursor / VS Code. It also fixes a stale comment.Tests
uv-installed environment. This new template now makes the UI show "Databricks Connect enabled" in the bottom status bar
