The product is intentionally narrow. It does not try to be a full payroll engine or a legal-advice surface. Its job is to make the key SMP rules more legible and to route the user into the page that best matches the question they still need to answer. That is why it separates the calculator, methodology, FAQ, and guide pages instead of cramming every support surface onto the homepage.
The source posture is straightforward. Non-durable figures are shown with a reviewed date and authoritative source link. The logic is written so the data can change without rewriting the product. That means someone can still use the tool in the future without blindly trusting an old embedded threshold.
