Greptile Overview

Greptile Summary

This PR fixes a data integrity bug in the subscription system where customers with only canceled/inactive subscriptions in a product line were not receiving their include-by-default products.

Key Changes:

• Modified getSubscriptions() to check isActiveSubscription() before tracking product lines with subscriptions
• Ensured that product lines with only inactive subscriptions are treated as having no active subscriptions, allowing the default product to be included
• Added comprehensive test coverage for the scenario where only inactive subscriptions exist in a product line

Impact:
The fix ensures customers always have access to their free tier or default products when they cancel paid subscriptions, preventing loss of base functionality.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The fix is surgical, well-tested, and addresses a clear data integrity bug. The change adds a single condition check that correctly filters out inactive subscriptions when determining product line availability. The new test case provides comprehensive coverage of the edge case being fixed.
• No files require special attention
