Every declaration is pinned to a version
When you declare human authorship, the record stores which version of the Human Authorship Standard was in force, and copies the exact wording you agreed to.
Changes don't apply retroactively
If the standard changes, a new version is published with its own effective date. Declarations made under the old version keep their original meaning.
Tool classification is versioned too
A tool that's allowed today could be reclassified later as the technology changes. The new classification applies to the new version, not to work you already listed.
Where to look
The standard, its version history, and the current classification of every catalogued tool are all published. If a change needs you to agree again, we'll ask.
