None
None (slug none) is the default engine and the baseline every test case
supports. The run provides no runtime, so the build supplies its own frame loop,
input handling, audio, asset loading, and diagnostics.
A case run under none measures a model building a game from nothing. Its
specification states the whole deliverable, and nothing about the build is
provided.
Instrumentation
Section titled “Instrumentation”Because no engine host exists, a none run is driven through the
instrumentation the case mandates:
a debug API on a case-specific global, a render-free core beneath it, and a
read-only debug overlay. That contract is written by the model, so it is
load-bearing. A build that does not expose it fails the checklist points its
absence hides.
Documentation
Section titled “Documentation”The seeded files are the case’s own specification, assets, and reference media, and the rendered prompt names no engine.
