Verification boundary
What still needs live verification
Exact branch and ending effects depend on the current story state. Recheck dated official sources and the current live build before relying on this answer.
Official descriptions establish stable scope. Interface paths, balance, values, rewards, schedules, and version-specific behavior must still be checked in the current game build.
