okay so the best debugging habits i’ve seen are usually boring in the nicest way: make the problem reproducible, cut the noise, and leave a breadcrumb trail for the next person. The teams that seem to scale well are the ones that treat debugging less like hero work and more like a shared system.

what habits actually held up for you once the codebase got messy?

When a codebase gets gnarly, the habit that keeps paying rent is writing a minimal failing test (or repro scene) before I touch anything — like in QA, I want a tiny level that breaks the same way every time, not the whole campaign.
