I have a customer who is asking this question and I did know the answer.
The only references I have observed was on customer prints or
documentation. Can anyone help?

We're searching for a standard (IPC ?) which defines the numbers of
repairs allowed under different circumstances. All I have here is
IPC-7721A, which details repair methods, but doesn't  explain the
extent of acceptable repairs.
IPC-A-610 doesn't appear to address this, either.
Checking an IPC catalog, I don't find a document description that fits.

In particular, our test repair group is looking for guidance on how
many jumper wires (to repair broken traces in the flex portion of PIC
Data boards) would be considered acceptable.
Are you aware of standards that define such criteria?
