Configuration hierarchy

DataMuru uses separate files to keep concerns reviewable.

1. datamuru.yml selects project-level contracts.
2. environments/*.yml carries environment metadata.
3. providers/*.yml configures provider connectivity and execution.
4. workspaces/*.yml declares resources and principals.
5. governance/*.yml declares taxonomy, roles, assignments, and masks.

Paths are resolved from the directory containing datamuru.yml.

The alpha loads the configuration for default_environment. The Python API accepts an environment argument, but project loading and file selection remain intentionally conservative while richer overlays are developed.

Keep environment-specific credentials outside YAML. Use environment variables or a secret manager.
