Tracking Rules
How this site should handle claims before they become reliable wiki facts.
Only state facts that are visible on official pages or store listings.
Do not invent creature names, item locations, recipes, or biome layouts before they are confirmed.
Use planning advice for pre-launch pages, then add discovered in-game details after Early Access opens.
Keep official sources linked so readers can verify release, platform, and system requirement details.
