If you have a bundle context, you can use b.CacheDir() for this.
It goes into .databricks/ which is typically already present in the .gitignore file.
You can use the git.NewRepository() and fileset packages to get a list of non-ignored files in a tree. We use this for synchronizing files into the workspace tree for bundles and for the sync command.

- State file now stored in .databricks/bundle/<target>/app_validation_state.json - Validation without bundle context runs but skips state save - Deploy always has bundle context so state is always managed

This is a different "state" you're dealing with here.
You can use b.CacheDir() with an apps-specific suffix.
Store state in .databricks/bundle/<target>/apps/ instead of directly in .databricks/bundle/<target>/ to avoid confusion with bundle's own state. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Changes
Add validation state machine for Databricks Apps that auto-validates on deploy when needed:
.databricks/bundle/<target>/app_validation_state.json--skip-testsflag (tests always run during validation)--skip-validationflag to bypass validation entirelyWhy
This change enforces the validation: users can only skip it when they explicitly use YOLO flag
--skip-validation.Tests
Added unit tests for state management (
state_test.go):
