Pulled in as far as the geometry allows. The seal face now runs from the far jamb
straight back to the wall, so the shallow side is zero and there is no vestibule to cross —
what is left is the wedge the 22.5° turn costs, and nothing else.

Zero on the shallow side is real, not a rounding. A container backed in on that axis already
reaches the building at the far jamb — its own corner is what closes the gap. So there is nothing
for a wall to do there, and holding it off by 5.3 ft was pushing the truck out for no gain.
It stops being a room. At 23 ft² you have a seal frame, not a vestibule a forklift crosses.
That suits the edge-of-dock leveller you already run — 7 ft across, 1 ft out — which needs
no floor behind it, and it is less insulated envelope to build and hold.
It cleared the apron rule on the site map. The packhouse card read truck apron leaves the
property at the 8 ft house. Pulling the face in 5.7 ft brings the whole 115 ft strip with it, and
both buildings now read clear at 22.5° — no need for the 27° the notes used to call for.
The one thing to settle with the vendor. The wedge tapers to nothing, and you cannot build to a
knife edge — expect the last 18 in to be poured as a guide curb rather than framed as wall, which is
what you want anyway where the container's corner comes that close to the building.
48 in dock plus an edge-of-dock leveller is still the open question. Those bridge roughly
±5 in of bed height, and a container on a chassis sits high. If the vendor pushes you to a pit
leveller, the floor comes back and the wedge grows again.
