The pattern has been named and a card for it created, with perhaps a bit of initial information entered.
At least the Heart field and 2 additional fields (author's choice) have text entered in them. This might only be rough text or notes.
The Heart and Description fields, and Related Patterns (both the list and the explanations of how those patterns are related) are filled out, with descriptive text that reads in a more polished way (rather than just rough notes or an initial list of points), plus at least one other field (Visual, Examples, Resources, etc.).
All fields are filled out (including Visual), and some significant thought has been given as to how this pattern fits into the whole pattern language.
