(Above: Due to past-Jacob leaving about 1/4″ of galvalume jutting over the edge of the plywood on the Closet-wall’s west side, I decided to fasten this piece of trim under the metal sheet rather than over it. As can be seen, the discrepancy is barely noticeable.)
Active Summary: Today I began Jacobhouse activities by obtaining measurements for all vertical trim locations and for along the kitchen’s base. This was followed by the hacksaw-times. By this, I mean I spent the ensuing hour and a half cutting all of the lengths of trim required by my measurements. This was followed by the drilling of many holes at measured / marked intervals and then by my bringing all of the kitchen trim inside. Therein, I proceeded to rivet trim along the kitchen base as well as beneath the sub-counter. The main spot of difficulty was in riveting the aluminum along the kitchen base where I had to contend with some very brittle wainscoting. Despite this, I finished off the morning with the kitchen almost entirely trimmed.
(8:20 PM Update): I was able to work quite a lot at Jacobhouse this afternoon on account of my arriving early and leaving late. During this time, I finished installing the last bit of trim in the kitchen and fastened all remaining vertical pieces in the hallway, bedroom, and office.
TIL: Today I learned that when using aluminum angle-stock as trim, it is best to procure and utilize 1/16” stock. This lesson came about through my making at least twenty cuts via hacksaw through ½”, ¾”, 1″, and 2″ angle-stock*. The latter three were 1/8” thick whereas the ½” was 1/16” thick. I had the fine fortune of cutting the ½” after the other types, so when I did so, it felt like I was sawing through paper.
Commentary: Though this morning was made somewhat frustrating on account of my impatience to move into Jacobhouse, it was highly productive. I really look forward to vacuuming up the mess of wood-dust and metal shards that I made today.
Though these were probably the easiest pieces of trim to install, one of them (the north piece) fell on me as I was working on the south side. It bashed me atop the skull. Was unpleasant. Fortunately, aluminum is a very lightweight metal. 
Out of all the corners in Jacobhouse, the bedroom’s West corner joint was the portion I looked forward to trimming most. Now, not one sliver of plywood is showing. 
Additional trim for the pocket door’s jamb. 
Aluminum trim along the kitchen base. Padre helped me with the corner just beneath the fridge (placed a spacer behind the 1″ joint-cover). 
Somehow, this ended up looking better than I originally thought it would. There was some slightly difficult on the bottom left corner due to the aforementioned brittle wainscoting. 
A colorful dawn. I find it interesting how dusk always seems more carroty in hue whereas dawn is more rosy.
Final Note: Tomorrow I believe the only trimming I must tend to is the piece above the sliding glass doors and the two pieces above the bathroom pocket door (both sides). This will require some ¼” or 1/8” rivets, so I will need to procure some of those from Sparr Farm Supply in the morning. After cutting / fastening trim above the doorways, I will affix the plastic drawers I received today within the closet wall where they will act as my shorts and sock drawers. To finish up the morning (or in the afternoon), I plan on vacuuming the whole house in preparation of moving my office and bedroom to their new location.
*In addition, I also cut through a piece of 1″ aluminum flat-stock.
