There's no limit in the spec on the number of rework cycles.
I remember something in an old version of MIL-P-28809, or
WS-6536 maybe, but we never had this imposed on us.
But if we did, we'd have a heck of a time assuring this. We'd
need to keep detailed maps of every component termination
that was ever touched, for every occasion that a soldering iron
was taken to the assembly. Or maybe not a map, but at least
a record of every reference designator, and every pin. Lots of
lead counting ..."Let's see, is that U13 pins 66 and 67 that
need touchup, or 67 and 68? Darn, start counting down the
row again..."
And how long would we have to keep this information? If the
assembly comes back from the field for some work, would we
have to go digging for those old rework/mod maps?

I am having people look, but if there is a limit I do not remember.
However, from a practical point of view, the answer is Doug Pauls'
patented (Or is that copyrighted or trade marked? Being a lawyer, I
don't know.) phrase, "It all depends".
**I just GOTTA find me a way to cash in on this supposed trademark or
