[eyelidlessness]

It depends on:

- what’s in the change; if I’m reasonably sure I understand it, and that it won’t have side effects, and that it’s the right thing to do, I may skip running it

- how familiar I am with the area of the codebase; even if the above is satisfied, I’ll pull it and explore around the change to look for potential side effects I’ve missed, or other approaches that might be better for maintenance… and generally to improve my familiarity

- how confident I am in the other contributor’s (and reviewers’) thoroughness; I generally scrutinize even trivial changes if I don’t think others have, because surprising things sometimes reveal themselves
