- pfgt/pfle/pfeq are always pipelined: fdest <- A-pipe retire, push undefined;
bit7 selects pfle (inverted CC sense) -- was misread as result precision.
316 pipelined compares in the firmware previously desynced the A-pipe.
- h_igcwait now models full consumption: done-status nonzero AND write-index
reset (+0x7f8=0), otherwise queue pages saturate at 0x7f0 across frames and
enqueueing silently stops (observed: even the per-frame marker item stopped
binning by cmd ~4300).
