• Task 3 (Job Scheduling): Scheduled Databricks Job from GitHub fork on hyf-dbt-warehouse with screenshots and orchestration comparison in task-3/SCHEDULING.md.

How to review

• Open task-2/WRITEUP.md to check initial vs incremental build times and DESCRIBE HISTORY output.
• Open task-3/SCHEDULING.md to verify the Databricks Job Run URL, screenshots, and Airflow comparison.
• Open AI_ASSIST.md for documented LLM interactions.

Secrets hygiene checklist

• No .env or profiles.yml files committed.
• No Databricks personal access tokens (dapi...) hardcoded in any notebook or SQL file.
