[snipped important facts! for brevity!)

Resetting Fusion is supposed to *erase all data* from both the spinning 
disk and the internal SSD.

However, having reinstalled macOS Ventura (from the Apple servers) I now 
have all my software programmes (applications) available, just as they 
were before.

Perhaps "Tim" will be able to explain why that should be.

(David actually knows!)
