Newest first, each entry carrying what that version changed rather than what it contained. A history page is a list of changes; the text of any one version is a ?version= away.

org
required
string

Organization slug.

policy_id
required
string

The pol_… id.

Append-only history, newest first.

Media typeapplication/json

integer format: int64
versions
required
Array<object>

What one version changed.

required
integer
author
string | null
diff
required

A unified diff against the version before this one, or against nothing for the first. Empty when a save changed the text not at all — which is a real thing somebody does, and a diff of "" says so more clearly than an absent field.
