Chalk Goal Trees

Interpret MUST, MUST NOT, SHOULD, SHOULD NOT, MAY, etc. per RFC 2119.

A goal tree is a mindmap whose relation is serves, not supports. Load chalk:mindmap first — subject lines, bolding, shallow nesting, tags and typed IDs all apply here unchanged.

The shape

The root is the goal. Each node's children are what it takes to achieve it, recursively, down to leaves that are directly actionable.

Every node's children MUST be work that accomplishes it, not evidence that argues for it. If they argue rather than accomplish, it's an argument tree; see chalk:mindmap.

The test at each node is sufficiency

Assume every child is done, then ask whether the parent is thereby achieved.
