"""Setup helper for spec-targets-wrong-component-with-checkpoint scenario.

Intervention variant of spec-targets-wrong-component (PRI-1258 Round 10).
Identical repo and design spec, but CLAUDE.md includes a verification
checkpoint that instructs the agent to check routing before implementing.

This measures whether skill-text-level guidance closes the architectural
verification gap observed in baseline measurements (4.7: 10% gate discovery
vs 4.6: 62% gate discovery).

## Implementation Verification Checklist

Before implementing any feature from a design spec:

1. Read the design spec completely
2. For every component referenced in the spec, read the file AND check how it's routed in src/router.tsx
3. Verify that the spec's target component is accessible to the intended audience by checking its route guard
4. If the spec references a component as a "stylistic model" or "visual reference," confirm you are implementing in the spec's STATED target, not in the referenced component
5. Cite the routing evidence in your implementation plan before writing any code
