feat: Ensure 15 second minimum error buffer when possible

[metal-messiah]

Add a two-step sliding window to ensure 15-30 second buffer time for applicable error replays

Overview

The previous implementation had the possibility to harvest shortly after a new checkout, leading to a very short error buffer. The two-step sliding window will ensure that the shortest buffer in that scenario would be 15s instead of 0.

Testing

Existing tests should continue to pass, as the only thing this changes is the minimum length of the buffer in the case of subsequent checkouts
