My handling is that Event A logs B, and B is only passed to the
process system IF A C&C's successfully. If A doesn't C&C, then the
log of B of course doesn't exist as it would have been created by
something that doesn't exist etc.
I find its quite common for my code to be logging follow up
(daisy-chain) events.

Precisely.

Not merely chaotic, but impossible to guarantee either logical state
or logical consistency.
