vgsp: sema_gr_setup_hold_ms param (default 0) - setup-push detect (>=12288B or MME-setup families in scan), hold arm on first unreadable read with 8x4K demand to stalled-VA channel, deadline consult at consume gate; r1079-readable setup captured words=511 (contrast r1083/85/87 zeros = setup-push read lottery root); hold fired but guest resolver covers only 0x120000000-0x121000000 - next: extend resolver to GL pushbuffer VA families - SESSION 153 r1083-r1087
