Inspections
Which standing checks Minerva runs over your thoughtbase, and what "stale" means for the way you work. Findings show up in the Inspections panel in the right sidebar; this page is about deciding what gets pointed out in the first place.
Choosing which checks run
Each check has a switch and a line saying what it looks for, grouped by what it's about: Notes, Links, and Sources. Everything is on to begin with. Switch off anything that isn't telling you something you'd act on — a thoughtbase of daily journal entries doesn't need to hear that its notes are old, and a set of working drafts doesn't need every unfinished link flagged.
Enable all and Disable all are there for the two moments you want them: setting up, and starting over.
A check you switch off isn't quietly filtered out of the results — it doesn't run at all. Several read your whole knowledge graph, so switching off the ones you don't want makes a run over a large thoughtbase noticeably quicker. That applies to the automatic runs too, not just the ones you ask for.
Changes take effect on the next run — which is usually a couple of seconds after your next save. Press Run in the Inspections panel if you want the list to catch up immediately.
How long is "a while"?
Two checks measure time, and neither has a right answer that suits everybody:
Each field appears only when its check is on — a dial for something that never runs is just clutter. Values are kept between 1 day and about ten years.
These settings follow you, not the thoughtbase
Inspection preferences are stored per machine, alongside your other app settings, rather than inside a thoughtbase. They're a statement about how much you want to be nagged, not a property of the notes — so they apply to every thoughtbase you open here, and opening the same thoughtbase on another computer uses that computer's settings.
