# Meld address forms

**🟢 Beginner · Lesson 26**

THE ADDRESS LAW (run-proven + doc-canon): every spell lives at one (frame_key, binding_key) address - frame_key is your spellframe, or the spell's normalized name if you gave none; binding_key is your binding_name, or the default slot. Human callers use a quoted spell name; machine callers use an explicit spell_id. A categorized registration also has a complete (spellframe, binding_name) address. A name alone does not supply a custom spellframe.

## Before you run
