test_tiered_execution_optimization fails with ModuleNotFoundError due to incorrect patch target

[shiwani42]

What is the issue?

test_tiered_execution_optimization in gap_analysis_db_test.py errors with ModuleNotFoundError because patch("application.config.Config.GAP_ANALYSIS_OPTIMIZED") treats Config as a submodule of application.config. Config is a class, not a subpackage, so the mock importer fails. The test can never run, leaving the tiered gap analysis optimization feature with no test coverage.

Expected Behaviour

The test should run and verify that Tier 3 is skipped when Tier 1 returns results.

Actual Behaviour

ModuleNotFoundError: No module named 'application.config.Config'; 'application.config' is not a package

Steps to reproduce

1. Run the test suite: flask test
2. Observe the error on test_tiered_execution_optimization in gap_analysis_db_test.py

Hi @Pa04rth, is this a valid issue? Happy to raise a PR if so.

Hi @shiwani42, I’m replying here since I worked on the tiered gap analysis implementation in PR #716 and the follow-up changes in PR #717.
I checked this again on the latest main, and I’m not able to reproduce the reported failure on my side.
test_tiered_execution_optimization runs successfully and validates the intended Tier 1 prune behavior, and I did not encounter the reported ModuleNotFoundError during verification.
@northdpole @Pa04rth , tagging you here as well for visibility.
If you still see a discrepancy, please share the traceback and environment details and we can look into it together.
