(Above: An afternoon’s worth of work fastening all of the morning’s PVC ‘lumber’ in place.)
Building Summary: This morning’s primary activities consisted of preparing / putting a brisket in the oven for lunch, filling ten Moo-Magic bags for the manure stand by the road, and planning / measuring / marking / cutting a multitude of PVC planks and aluminum angle/rectangle stock to fit around the interior of Jacobhouse’s entrance. Alas, I was unable to fasten any of those boards / aluminum in place before heading home for the morning.
(8:00 PM Update): On account of a light farm afternoon, I was able to work on Jacobhouse while a contractor and his work-companion dug the ditch for* the permanent DSL line. (More in TIL). Either way, during this time and for a while after, I modified / placed / fastened in the PVC frame boards and aluminum I had earlier cut. This was followed by a bit of clean-up which included sweeping and vacuuming up all metal shards remaining from drilling through the container’s internal hull and through the 2″ aluminum angle-stock that I ended up riveting to the door sill.
Thawed brisket ready for a good bit of rubbing. (For some reason, in this picture, it looks like leftover lasagna.) 
Rubbed brisket ready for the oven… of course, it needs to be covered first! 
Some of this morning’s time was spent filling more bags for the Moo-Magic Stand. 
A morning’s worth of measurements and cutting. 
This is the result of last night’s carbonara noodle shenanigans.
TIL: Today I learned from Wag that whilst using a cellular hotspot, not only does he get 6 times the amount of download power, he experiences very little MS (the delay between clicking something online / in an online game and the action that subsequently follows). It is unfortunate I discovered this on the very same day that Centurylink installed the permanent line to Jacobhouse. Nevertheless, the hotspot strategy may be utilized in the future. Six times the speed for the same cost (or less) in addition to an included phone plan and not supporting the Centurylink monopoly in our area… that all seems worth it.
Commentary: Despite my being able to cut all the PVC and aluminum needed for framing in the front door’s interior this morning, I was slightly dissatisfied by the progress I made. I had expected to at least fasten one board in. Thankfully, due to this afternoon being quite light (and Padre kindly allowing me to work on Jacobhouse instead of engaging in cow shenanigans), I was not only able to fasten in all that I had cut this morning, I was able to cut and fasten in an additional portion that I did not think I would be able to tend to today**.
Another quick highlight I should mention is that one of my part-interest cows, #326, calved today. It was a large Belgian (British?) Blue calf, and when we found the two of them in the early morning fog, they were both getting along quite well. This evening, though, while Padre and I were riding around the beefer pasture, we saw that #326 was calling for her calf. It turned out that her calf had hid itself out of reach beyond a low-hanging fence. Thus, I went over the fence to prompt him back out to his mother. I drew near to the youngling so as not to startle him, but my efforts were for naught. The newborn beast quickly stumbled to his feet at my approach and after bellowing, proceeded to ram me in the knee with a hard and not-so-little skull. He was a feisty calf, but I did eventually get him back out to his mother.
Final Note: Tomorrow I plan on cutting a couple more trim pieces, fabricating a form for the intended concrete window sill below the air conditioner, and possibly even pouring that form if opportunity allows.
*They had a little ditch digger that dug the 1-foot deep hole (about 300 feet long) in less than ten minutes.
** The sill just beyond the door. It consisted of a 5.5″ PVC trim board laid atop some PVC trim spacers, and on the inside edge, I was able to rivet on a piece of 2″ aluminum angle-stock.
