Ok.
I was reading the second quote above as saying that the pistons were retracting too far.
But maybe I have the wrong end of the stick .....?

The mention of "considerable" corrosion is ringing alarm bells.
How does it look now ?
If the rod was binding somehow then, although you appeared to have free play at the lever the hydraulics may still have been under a small residual pressure, closing the path to the reservoir and so on.
Your bench test of the hydraulics has not confirmed the function of the mechanical actuation, ie lever to rod to master cyl.
Not being picky, just trying to be thorough.
And anyway, we do love a brain teaser.
