+"""DIMENSION 2 Q3/Q4: readers for the refusing modes + SBC/Objectives bytes.
+
+HYPOTHESIS: for season/draft/tournament the gate byte is read only to be
+republished to the script layer (publisher) or to gate an unrelated sub-panel, not
+to open the mode from a server response. SBC/Objectives have settings fields
+(0x1fd2c/0x1fd42/0x1fd28, 0x1fd44) but NO IS_* publisher name; find their readers.
+
+CONTROL: the applier FUN_18011dc50 must contain `mov [rdi+0x1fd3a],al` (season)
+preceded by a `cmp [reg+FIELD],1 / sete al`, giving the season struct field index;
+we already know trading is field +0x28 -> byte 0x1fd2e, so that pairing in the same
+decompile validates the field-index reading.
