How validation works
Every rule comes from the game's own data: attachments list the weapons they fit and the slot they occupy, weapons list their slots, ammo carries its calibre, backpacks their storage grid. A red message means the data says it can't work; a yellow one means the data can't confirm it — items missing inventory-grid or compatibility data are flagged unverified, never silently guessed. Weight and cost total live as you build, and with your bank set in My Profile the rail shows how many full respawns of this kit you can afford — the number that actually decides fights in WARDOGS' persistent economy.
