MDFC Merge Rollout (2025-10-02)

Summary

  • Staging environment refreshed with the MDFC merge permanently enabled; compatibility snapshot retained via DFC_COMPAT_SNAPSHOT=1 during validation.
  • Commander catalog rebuilt with python -m code.scripts.refresh_commander_catalog --compat-snapshot, generating both the merged output and csv_files/compat_faces/commander_cards_unmerged.csv for downstream comparison.
  • Diff artifact logs/dfc_catalog_diff.json captured via python -m code.scripts.preview_dfc_catalog_diff --compat-snapshot --output logs/dfc_catalog_diff.json and shared with downstream consumers.
  • ENABLE_DFC_MERGE guard removed across the codebase; documentation updated to reflect the always-on merge and optional compatibility snapshot workflow.

QA Artifacts

Artifact Description
docs/qa/mdfc_staging_checklist.md Latest run log documents the staging enablement procedure and verification steps.
logs/dfc_catalog_diff.json JSON diff summarising merged vs. unmerged commander/catalog rows for parity review.
csv_files/commander_cards.csv Merged commander catalog generated after guard removal.
csv_files/compat_faces/commander_cards_unmerged.csv Legacy snapshot retained for downstream validation during the final review window.

Automated Verification

Check Command Result
MDFC land accounting python -m pytest -q code/tests/test_land_summary_totals.py Passed
Commander primary-face filter python -m pytest -q code/tests/test_commander_primary_face_filter.py Passed
Commander exclusion warnings python -m pytest -q code/tests/test_commander_exclusion_warnings.py Passed

Downstream Sign-off

Consumer / Surface Validation Status
Web UI (builder + diagnostics) MDFC staging checklist smoke QA Complete
CLI / Headless workflows Targeted pytest suite confirmations (see above) Complete
Data exports & analytics logs/dfc_catalog_diff.json review against commander_cards_unmerged.csv Complete

All downstream teams confirmed parity with the merged catalog and agreed to proceed without the ENABLE_DFC_MERGE guard. Compatibility snapshots remain available via DFC_COMPAT_SNAPSHOT=1 for any follow-up spot checks.
