The symptom
Pilot geometry contained many open boundaries and unverified modular joins.
What was tried
Inspect originals, preserve them, and review local derivatives.
What the evidence supports
Materials and presentation were explored; snap and runtime gates remained.
The lesson
Separate parts are not automatically usable modules.
Production readiness blocked in the inspected pilot record.
Evidence & perspective
- Original forty-building design manifest and pilot review
Forty design records exist. The pilot required modular rework; forty specifications do not mean forty production-ready game buildings.
