Summary for 2025-09: Completed a critical bug fix in the edu_edfi_source ETL to address transcript deduplication. The fix stops duplication caused by the annualized dim_course key generation by switching to non-annualized course observables, ensuring transcript metadata from the submission year is correctly linked and preventing fan-out. This improves data integrity, stability of downstream analytics, and trust in reporting derived from the ED-Fi source. The change was implemented and committed as part of PR #150 (commit d2e5d616a9f2a57f6f9179c7c7c73a9d23bb66d7).
