What this catches

The first-order mismatch: too little capacity, unsafe wattage, weak turnover, missing coverage, or a budget that ignores supplies.

What it cannot catch alone

A single calculator cannot verify every product, livestock choice, chamber fit, vendor listing, or future stocking plan.

Why open the planner

The planner combines this result with equipment categories, budget tier, bioload, and compatibility rules.
