Complete Slice D4 by adding aggregate lifecycle occupancy and traffic facts, validating physical source reports, and including decoded audio under the typed startup budget. Exercise every domain under forced pressure and retain the real cache/fence convergence gates.
Define Slice D's transition and concurrency contract, add generation-safe asset handles and owner leases, and parse the existing cache ceilings through typed runtime budgets. Stale generations cannot release or revive replacements, and worker observations are bounded and coalesced.
