using a 16197427 ecm with BDYT memcal ($od) on a 4.3 liter tbi engine,
does anyone know what triggers the "hot restart flag" and what happens when it is active?

Hot restart flag is used for what it describes with its name. $0D has fuel modifiers based on temp etc. Here is a section from the disassembly for $0D.
;---------------------------------------------
; CRANK FUEL MULT Vs. Vs. RPM IF HOT RESTART
;
;
; TBL = MULT * 256
;---------------------------------------------
ORG $4DAC ; MULT RPM
;----------------------------------
L4DAC FCB 255 ; 0.996 0
L4DAD FCB 255 ; 0.996 100
L4DAE FCB 166 ; 0.648 200
L4DAF FCB 166 ; 0.648 300
L4DB0 FCB 128 ; 0.500 400
L4DB1 FCB 128 ; 0.500 500
L4DB2 FCB 128 ; 0.500 600
L4DB3 FCB 128 ; 0.500 700
L4DB4 FCB 128 ; 0.500 800

You can search the disassemblies here for lots of Parameters in $0D.
