Public badges show the main survival and store systems
The checked list confirms furniture placement, Captain Clark, rope traps, Mimic, Still Life, sanity pressure, Codex progress, full store-day completion, and developer encounters.
Treat each badge as evidence that a system exists, not as proof of exact formulas. The list can help you decide whether to read the survival guide, co-op guide, stockroom guide, furniture guide, or entity page next.
