Fixes #2402

Problem

dbt Fusion (the dbt v2 engine) writes source freshness statuses capitalized (Pass, Warn, Error), while dbt-core writes them lowercase. normalized_source_freshness_status only matched lowercase values, so Pass reached the report unchanged. The "Last run status" cell found no entry for it in the report's status map, rendering threw, and the test-results page went blank.

Fix

• normalized_source_freshness_status compares and returns lower(status). edr applies it when reading dbt_source_freshness_results, so rows that are already stored are fixed too, not just new ones. The source freshness alerts use the same macro, so a Fusion Error now normalizes to fail there as well.
• SourceFreshnessAlertModel gets an is_runtime_error property that compares original_status case-insensitively, used by error_message and summary.

Testing

• New unit tests in tests/unit/monitor/alerts/test_alert_models.py cover both casings for runtime-error and other statuses.
• The rest of tests/unit was unchanged by this PR (run on Windows, where some timezone and fixture tests already fail on master).
• Confirmed the cause on a BigQuery + dbt Fusion 2.0.8 project: lowercasing the stored statuses made the test-results page render again. The macro itself was not run end to end against a warehouse.

Summary by CodeRabbit

• Bug Fixes

  • Source freshness statuses are now handled consistently regardless of capitalization.
  • Runtime errors reliably display the appropriate failed-freshness messaging.
  • Status normalization consistently maps error states and preserves expected outcomes across dbt environments.
  • Freshness alerts now correctly distinguish runtime errors from other error, warning, and passing statuses.

• Tests

  • Added coverage for capitalization variations of runtime error, error, warning, and passing statuses.

📝 Walkthrough

The source freshness status macro now lowercases statuses before mapping or returning them. The alert model now recognizes runtime-error statuses without regard to case. Unit tests cover both behaviors.

Changes: Source freshness status handling

Layer / File(s)	Summary
Normalize source freshness statuses elementary/monitor/dbt_project/macros/utils/normalized_source_freshness_status.sql	The macro lowercases input statuses before mapping error to fail, mapping runtime error to error, or returning other statuses.
Handle runtime-error casing in alerts elementary/monitor/alerts/source_freshness_alert.py, tests/unit/monitor/alerts/test_alert_models.py	The alert model uses a case-insensitive runtime-error check for its error message and summary. Tests cover runtime-error and other statuses with different casing.

Full details: Linked Issues check

Explanation

Issue #2402 requires case-insensitive source-freshness status normalization and runtime-error alert handling. The macro applies lower() and maps error to fail and runtime error to error, which covers Pass, Error, and Runtime Error. The report path applies this macro to stored freshness rows, including existing rows. SourceFreshnessAlertModel.is_runtime_error compares status values case-insensitively, and error_message and summary use it. Unit tests cover both runtime-error casings and other status casings.

Full details: Out of Scope Changes check

Explanation

The changed macro directly implements issue #2402 normalization. The alert-model change directly implements the required Fusion runtime-error behavior. The test changes verify the alert behavior and do not add unrelated functionality. No unrelated changes are shown in the supplied change summary or inspected files.

Assert the runtime-error error_message.

The tests cover is_runtime_error and summary, but not the separate error_message branch. A case-sensitive regression in that branch could pass both current assertions and cause Fusion alerts to render result_description instead of the runtime-error message.

Suggested fix

         alert = _make_source_freshness_alert(original_status=status)
         assert alert.is_runtime_error
+        assert alert.error_message == "Failed to calculate the source freshness\n```None```"
         assert alert.summary.startswith("Failed to calculate the source freshness")
