Done! she cries in triumph. These took a month exactly to knit, but for some reason it felt like forever. Perhaps it was that I set them aside in despair for a week, after I misplaced my notes -- found as I was beginning the second toe, behind the couch, which was not where I'd left them, I assure you.
I modified the pattern somewhat, to accommodate a larger foot than in the original -- I added an extra brioche rib repeat, so there were 6 more sts to contend with when it got down to the heel. This wasn't terribly difficult, but I did also have to realign the placement of the brioche rib on the instep as well, since 3 of those extra 6 sts had to go on the bottom of the foot and it didn't line up the same way as the original. I also worked the leg to 7 inches, instead of the 8 specified, as the rib at the top was very tight even just one inch higher (the brioche is much stretchier than the plain rib), and I lengthened the heel flap to fit better on a high instep. The toe seems rather narrow as written -- I would (will?) change this for my own pair.
All in all, I like the pattern very much and will add it to the list of things to make for myself! Hope my sockpal is pleased, too --
