+# roadmap-placeholder
+
+## Goal
+
+Bootstrap the spec + roadmap workflow for core. Future feature work uses
+`docs/specs/<date>-<slug>/{spec,tasks}.md` with YAML frontmatter and regenerates
+`docs/roadmap.md` from spec `status:`.
+
+## Next
+
+Replace this placeholder with real proposed / active / shipped specs as work
+lands. See companion repo `ai-dev-toolkit/kit/specs/README.md` for the tooling
+(`python3 ~/.claude/rag-index/specs.py new|list|ship|roadmap`).
