Codecov threshold enforcement limits on free tier

Codecov provides a free tier designed for low-traffic repositories, offering basic coverage reporting and pull-request annotations. While the v2 API supports coverage threshold configurations, the documentation does not explicitly confirm if enforcement logic is active for non-paid accounts.

There is uncertainty regarding whether the status check will successfully trigger a CI build failure when the reported coverage falls below a defined threshold on a free plan. This behavior is critical for small projects seeking to maintain code quality standards without upgrading to the Starter plan immediately.

Please clarify the following:

• Does the free tier enforce and return a failure status when a coverage threshold is not met?
• Is the POST /projects/{id}/thresholds endpoint functional for free-tier accounts?
