What does the “integrity” attribute of equipment mean

Solved - USER ERROR

I realised last night that this was down to me not clicking Apply after making my changes and pressing "ESC". In my defence ESC does exit other screens in the game without abandoning changes so it might be useful to include a warning if there are unsaved changes on the keybinding change but I will suggest this on the dev forum.

I can't find official documentation on this either, but according to this Frontier Forums post and others like it, ship integrity represents general wear and tear on your ship that's independent of hull integrity and module integrity. It has an effect on your hull integrity though, and module performance (reportedly).

• Low ship integrity directly correlates to a drop in hull integrity. When your ship integrity reaches 0%, your hull will effectively be at 70% integrity, even if the hull is fully repaired.
• Low ship integrity may cause modules to malfunction more often, some posts I saw cited a 30% chance.
• Ship integrity repair cost increases exponentially, so at 95% integrity it may cost 10,000 credits, at 90% it may cost 100,000 credits.
• As ship integrity decreases, so does your ship's paintjob quality...

That's literally all the information I could pull together, relegated to just facts mentioned by more than one user, and only stuff that isn't contradictory. I'll edit if I find anything from official or tested sources.
