I asked around and I'm not sure where there are concise, detailed instructions of how that works. I asked another developer, Erik, to review the lines you put together. You're very close, but had 2 lines incorrect. The corrected versions are noted below, with "**Corrected**".
So, for a 15 minute time period, you actually have multiple files being effective. In that case, the one with the latest start effectivity (02:45-03:30 and 09:45-10:30) is used.
23:30-00:30: 6hr forecast from 18:00Z
00:30-01:30: file1 generated from interpolate between 6hr and 9hr forecast from 18:00Z
01:30-02:30: file2 generated from interpolate between 6hr and 9hr forecast from 18:00Z
**Corrected** 02:30-03:30: 9hr forecast from 18:00Z
02:45-03:30: 3hr forecast from 00:00Z
03:30-04:30: file1 generated from interpolate between 3hr and 6hr forecast from 00:00Z
04:30-05:30: file2 generated from interpolate between 3hr and 6hr forecast from 00:00Z
05:30-06:30: 6hr forecast from 00:00Z
06:30-07:30: file1 generated from interpolate between 6hr and 9hr forecast from 00:00Z
07:30-08:30: file2 generated from interpolate between 6hr and 9hr forecast from 00:00Z
**Correct** 09:30-10:30: 9hr forecast from 00:00Z
09:45-10:30: 3hr forecast from 06:00Z
