Role: product and architecture critic.

Objective: Challenge whether Harness Kit should fold Open Design ideas into
its design skills and primitives.

Scope:
- Treat Open Design as inspiration, not a dependency.
- Protect Harness Kit's existing boundaries: no semantic workflow engine,
  cross-harness first, skills self-contained, evidence-first, design critique
  requires rendered artifacts.
- Do not edit files.

Output shape, max 700 words:
- Underlying user outcome in one sentence.
- 6 materially different product/technical forms, each with failure mode.
- Recommended form and why.
- Blocking risks if Harness Kit copies too much.
- One oracle that would prove the chosen form is useful.
