+Revision ID: 0055
+Revises: 0054
+Create Date: 2026-05-27
+
+Adds the Scribe Rulebook hierarchy as a fourth top-level entity, sibling
+to Project. Rules carry a structural (statement, why, how_to_apply)
+triple. Projects subscribe to Rulebooks (many-to-many). See the design
+doc at docs/superpowers/specs/2026-05-27-scribe-rulebook-design.md.
