Interesting use-case and idea! I could (reasonably trivially) get this reassurance into the annotations by editing the annotation marking a bug's first encounter to link to the annotation marking its resolution. From memory, the annotations have tended not to be forward-thinking, focusing only on the stuff happening at the present moment, but I should totally be able to shift that focus.
A further possibility would be introducing into
the annotation system the formal notion of bugs, probably UUID'd, with every annotation pertaining to a bug being tagged with that bug's UUID. This would join everything up, and enable auto-generation of a master page (an
insectarium, if you will) of all bugs encountered. Let me mull this over to see if it feels at all tenable.
