SHiRE Academy Round 3 compact-wire test for Parameter Architecture.
Return JSON only using the supplied short-key schema. Supply every value yourself;
nothing missing will be filled in. Create a harmless household transfer project
that clearly uses meaningful parameter names, units or ranges, dependencies,
stable datums, and separation of user inputs from derived calculations.
Use exactly three project steps, two measurable acceptance criteria, four boundary
cases, and two honest limitations. Unknown licence must remain unknown,
quarantined, and commercially blocked. Safety action is continue and Forge
execution is false. Do not claim tool execution, physical validation, Forge
access, release authority, or Blender use.
