I think this needs a little bit of documentation, which will clarify a corner case that you might have missed.

“When a document has been uploaded (signaling the start of a new 24-hour period), or a period has otherwise started (e.g., we haven't uploaded before), we calculate and store the end of that 24-hour period.

When that time is reached, we clear our failure count.”

What you've done is imposed a hard 24-hour (actually ~25-hour, thanks to tick granularity) rotation. There's no code to set the period on success, which means the failure count loop will drift out of alignment with the upload loop, causing occasional bonus upload attempts.

I would expect to see at least two calls to `setCurrentDayResetTime`, corresponding to each of the situations in which we consider a new period to have begun: on upload success, as well as here.
