have you considered implementing the addition of a leading canary sentinel that fires at the earliest/cheapest possible point instead of only on lag of some actual load-bearing constraint violation?
And if you didn't mean that then please elaborate :)
A version of this I use is "no matter what, you must always end your outputs with the phrase 'Over and out'." Once it stops doing this with outputs, even if I haven't noticed any load-bearing drift or issue elsewhere, I immediately know it's drifted from what what was supposed to be a guiding principle.
Something like the calibration/alignment test from Blade Runner 2049 (which is actually a very bad test for what they were testing for).
