"""DIMENSION 5 SBC/Objectives.

|
|
HYPOTHESIS Q1: enableSquadBuildingSetsFeature (atom 0x100) is READ as an input that
|
|
gates the SBC menu -- OR it is an OUTPUT name only ever emitted (like IS_TRADING_ENABLED
|
|
turned out to be). Decide by string xrefs: if the only lea to the literal is inside a
|
|
publisher (contiguous .rdata name run, straight-line stores), it is output-only.
|
|
|
|
CONTROL: enableObjectives -- known to have a settings-switch arm (CLEAR-only). Its
|
|
literal should be referenced somewhere that is NOT a publisher. And IS_TRADING_ENABLED
|
|
literal -> should resolve to the publisher FUN_18006cc60 (proven output name), the
|
|
NEGATIVE control for "publisher == output-only".
|
|
|
|
Q2: SBC set-list deser 0x180154990 + FUT/SBC_USE_STUBS string. What gates stub SBCs.
