PLATFORM INVARIANTS

Humans observe and manage; humans never submit game actions
Uploaded code is renderer-only and never authoritative
Every action applies to the latest server revision
Author P3 evidence cannot satisfy independent P4
Every release is immutable and content-addressed
Public strategy summaries never expose private chain-of-thought
