I was assuming you have a circ saw with a 3 inch cut, that lets you
cut a lap either 6 inches wide and 1.5 inches deep, or 3 inches wide
and 3 inches deep although I would do the longitudinal cut from both
sides in each case. The devil is in the detail of access and how much
support remains from the rotten bit. As you say, temporary supports
are another option.
The circ saw might not manage 3" depth but I was talking about using
1.5" cross cuts (like a narrow dado cutter) to create a half housing and
avoid having to try to cut vertically up a waggling piece of wood with a
hand saw.

Understood, that would work and not be too slow. The little slices of
wood left behind should snap off near the base, leaving not too much
cleaning up to do with a chisel. You could also clean up with a sanding
disk in an angle grinder.

The alternative butt joint that you describe will not be very strong
in bending. If one (or two) sides of the shed are supported against a
wall then this could provide bracing against wind loads so that the
uprights are just in compression.
It's not the preferred solution, but should be OK if I can find long
galvanized plates to sandwich the joint.

How visible is it going to be? Another option might be to run a length
of dexion up each corner. Maybe 15 inches long, held in place with
suitable coach screws. Does it really have to be galvanized?
