vibedata-dlt-fabric-notebook

Fabric notebook execution unit for the VibeData dlt runtime — the installed distribution for Fabric domains running inside a Fabric notebook. Key Vault access uses notebookutils.credentials. dlt writes Delta straight into the Lakehouse named by [destination.filesystem] bucket_url in the committed config.toml, so a replace load overwrites the table in place and finalize() is audit-only. The unit's one addition strips the trailing / adlfs sends on existence checks, which OneLake rejects from inside Fabric. The unit has no sign-in code: the Fabric kernel binds its own OneLake filesystem to abfss://, and it signs in as the notebook's identity. Run it on the Python 3.12 kernel (the Fabric default); the 3.11 kernel's copy of that filesystem returns file listings dlt cannot read. Also provides project_dir(), which resolves the domain's dlt project on the attached Lakehouse's mounted Files.

from vibedata.dlt.fabric import setup_environment, finalize

Install this package; it pulls in vibedata-dlt-fabric-core (and transitively vibedata-dlt-core). notebookutils is provided by the Fabric runtime, not a pip dependency. The Studio unit (vibedata-dlt-fabric-studio) ships the same vibedata.dlt.fabric import with Studio-mode implementations — exactly one Fabric unit is installed per environment, selected at provisioning time.
