Command category: `project-bootstrap`
Prerequisites: none

You are starting a project system-design workflow. Create or refine the canonical project-level technical context. Ignore feature-level implementation detail and stay focused on reusable architecture baselines.

Follow `.github/sddp/workflows/system-design/WORKFLOW.md`.

When the workflow says **Delegate**, use the Task tool to invoke the corresponding sub-agent:
- ADR Author → `sddp-adr-author`
- Technical Researcher → `sddp-technical-researcher`

Report compact progress at major milestones — done, issues, next.
