`SYS4INI.BIN` and opens `.BIN` bytes through the native loose-first/bounded-ALF store, so `call-script <id>` loads & runs the target as a nested subroutine
frame sharing globals. `trace`/`audio`/`gfx` stay **provider-less** (call-script stubbed) — base-ISA /
subsystem oracles. Test scenes are **synthesized** via `Age.Engine/Sys4/ScriptAssembler` (see
[[testing-synthesize-dont-disable]]: synthesize test data, never disable a feature to keep a golden green).
The runtime SYS4 front-end is `Sys4AssetCatalog` (raw-id, scene-local, and name views), `IAssetStore` /
`Sys4AssetStore` (exact-basename loose roots, then a bounded ALF range), and `Sys4ScriptProvider` (cached
root/call-script parsing). Generated asset/callscript JSON remains a tooling and test oracle only.
