Box screwed together! Still missing one connector, though. And has a small/strange problem.
Box unscrewed, extensive testing of CHT input performed, heavy Jaguar review done, changes suggested by me, and performed by Andy, 10 wires replaced with appropriate ones for reliability reasons, box rescrewed, and tightened up properly, with (some) confidence.

This turns out to be a design flaw in the 0.6 and earlier boards. 0.7 should have this remedied. I started reviewing it, but didn't complete yet. Perhaps it can be released tomorrow if I pull finger and complete my review of the changes.
Also I lied:
- The value does change, but emstudio takes a while to show it due to resync of comms.
- The CPU does not stay dead, I fooled myself in this respect.
- CHT has 1.0uF and IAT only has 0.22uF hence no issue there. Topology thoroughly reviewed for both.
Tonight i stripped and soldered 40+ wire ends and am ready to join them together tomorrow. After that I'll swap it into the mighty hotel and see if it can handle a low-speed hall signal.
Obligatory pictures:
Dodgy wires replaced:

Nearly ready to go:

Haircut given to input wires:
