Experiment 30 classified two deferred documents against verified current state:
- architectural-principles.md → keep as task-specific reference (6 current, 4 aspirational, 3 duplicates)
- backlog info.md → retain temporarily pending revision (mixed mock fixtures + deferred UX planning)
Neither moved to archive — both contain material with potential near-term utility.
Created docs/document-role-review.md with evidence, routing test, and return-to-work note.
