Adopt the repo as the primary workplan anchor: repo_id becomes required, market-domain is derived from each repo's classification, and the domain/topic spine is demoted/retired (RepoGoal becomes the goal primitive). Add task T10 for the re-anchor plus the workstream -> workplan rename across schema/API/MCP. Add ADR-005 (Cross-Repo Workplans Live in Dedicated Project Repos): complex cross-repo efforts get their own project repo (category: project) as the anchor, retired to archive on completion with results living on in the modified product repos. Rewrite D1 as resolved and add D1a for the project-repo naming/archival convention. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
