Remove the legacy GameWindow apply path and make the concrete render, physics, and static publishers the only production owner graph. Serialize full-window retirement with shared-origin teleport and session boundaries so old coordinate-frame resources cannot survive into a new world or login.
Move full and near-tier presentation retirement out of GameWindow and into a concrete pipeline-owned stage mapper. Harden the retry ledger against reentrancy and committed visibility observer failures, enforce a single state/resource ownership graph, and split concrete versus legacy controller construction so callbacks cannot be silently ignored.
