Considering that we have these priority options agreed for Day 1 (T436) [...]
Where T436 is clearly unrelated. The numbering of the pre-import tasks should be restored, or the links/mentions should be fixed.
Yes, this is a bit annoying, but we can't invest the time to fix these links programmatically. We (as in everybody willing to help) are fixing them manually as we quote them or need to refer to them.
Maniphest's advanced search contains a field to find the old numbers of tasks. fl436 can be found in T268.
