Historical Migration and Planning Archive

This directory preserves historical planning blueprints, execution records, and design notes authored during the development and ring migration of redstring prior to adopting SpecOps (Project Management as Code).

Living specifications, product requirements, user stories, and architecture decision records now live version-locked under docs/project/:

• PRDs: docs/project/product/
• User Stories: docs/project/user_stories/
• ADRs: docs/project/adrs/
• Backlog: docs/project/backlog/
