+# MIGRATION CONFLICT FIX
+# Run these commands in order to resolve the migration numbering conflict
+
+# Step 1 - Check current migration state
+python manage.py showmigrations scanpipe
+
+# Step 2 - Check for conflicts
+python manage.py migrate --check
+
+# Step 3 - If conflict exists, find the latest migration number
+# Look at scanpipe/migrations/ folder and note the highest number (e.g. 0085)
+
+# Step 4 - Recreate your migration with the correct number
+python manage.py makemigrations scanpipe --name origin_curation_fields
+
+# Step 5 - Apply migrations
+python manage.py migrate
+
+# Step 6 - Run tests locally to verify
+python manage.py test scanpipe.tests.test_origin_models
+python manage.py test scanpipe.tests.test_origin_propagation
+python manage.py test scanpipe.tests.test_origin_api
+python manage.py test scanpipe.tests.test_curation_models
+python manage.py test scanpipe.tests.test_curation_utils
+python manage.py test scanpipe.tests.test_curation_schema
+python manage.py test scanpipe.tests.test_curation_commands
+python manage.py test scanpipe.tests.test_curation_pipelines
+
+# Step 7 - Run all tests together
+python manage.py test scanpipe.tests
+
+# Step 8 - Commit with sign-off and push
+git add .
+git commit -s -m "test: add origin curation and propagation test suite"
