SeedYuiAuthoredRetainedScheduler
Full authored lowering is admitted once at startup and after an explicit resize/layout reseed. The leading clear becomes the persistent frame's background clear; every remaining command is partitioned into stable shell or authored-node fragments without changing its clip/resource identity.
Turn YUI models into a working frontend and its rendering/input adapters.
external SeedYuiAuthoredRetainedScheduler(yuiAuthoredRuntime original runtime, yuiAuthoredApplicationLayoutPlan original plan, yuiDisplayList original display, text reason) returns yuiAuthoredRetainedSchedulerStatus: source-declared
Parameters
yuiAuthoredRuntime original runtime- Supply runtime as yuiAuthoredRuntime original.
yuiAuthoredApplicationLayoutPlan original plan- Supply plan as yuiAuthoredApplicationLayoutPlan original.
yuiDisplayList original display- Supply display as yuiDisplayList original.
text reason- Supply reason as text.

Notes and source
Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
