The MSX analyser is now smart enough not to be definitive when it's uncertain.
...
The cartridge type has also migrated to being a property of the cartridge, prefiguring my intention to discard the static analyser union.

Decided to focus on 'confidence' over 'probability'.
...
Besides anything else, it individualises the measure. E.g. two targets can each have a confidence of 0.8 without each giving the wrong answer about probability.
