95# Trusted system-construction adapter for the canonical transaction owner.
96# Supplies spawn/cleanup operations using the closed populate, clear, record and
97# relation declarations. populate receives the full World at deferred application;
98# clear must match its Clear declaration, and relation declarations must cover the
99# links cleanup is expected to maintain. These callbacks are schema/engine setup,
100# not extra runtime authority exposed to the polymorphic gameplay body.
