+"""DIMENSION 1 Q1: enumerate the userInfo.feature restriction vocabulary IN FULL.
+
+Hypothesis: FUN_18013ec10 (userInfo deser) handles atom 0x11c (feature) by entering a
+nested object-parse loop that dispatches sub-keys (trade=0x330 known) each writing a byte
+into the userInfo record. Enumerate EVERY sub-key and the offset each writes.
+
+CONTROL: the known trade atom 0x330 MUST appear and map to +0x17c. If it does not, the
+dispatch form assumed is wrong and the enumeration below is unreliable.
+
+Method: print full decompile length + full text of FUN_18013ec10, then scan for the
+feature atom 0x11c and identify the nested parser (a callee entered at that case), then
+decompile that callee in full too.
