- ScriptAssembler (Age.Engine/Sys4): assemble code+strings -> Script (inverse of
Sys4Loader; also Phase-D modding-assembler groundwork).
- SyntheticSceneTests: deterministic show-text/wait/nested-call-script/shared-global
scene run with call-script handling ON.
- WaitForInputTests: reworked onto a synthesized two-page scene (was: SC0000 stub=186).
- RecoverTests: full call-script handling via a no-op subroutine double (isolates
RECOVER's ISA semantics from real subroutines' game-state deps).
- Retire TraceDiffTests: it matched the C# VM to vm0.py's stubbed-call-script trace;
vm0.py is retired from oracle duty, and we no longer gate handling to keep it matching.
