• Completion Report
• Normative contract and player documentation

Product Main approved proceeding after ANU-10 with Unity/Vuplex integration testing and performance testing deferred. Those deferrals are explicit non-goals for ANU-11 and must not be reported as verified acceptance evidence.

Main, Companion, and Emphasis use the same surface-document rules. Transparency is an optional per-surface player capability and is not required specifically for Emphasis.
