The stub run does not park at HOST PORT - 15. Both DUART failures are reported,
the board LED blinks once (finite L3F208660), TYPE 'GO' TO CONTINUE is printed
(no input is read), and the level-1 runner continues ('CONTINUING THE TESTS').
The runner never returns to 3F204440, so 3F208060/3F208650 are never executed.
The run then wedges at frame ~2839 in a DUART1 counter-ready interrupt storm:
the ISR polls DUART1 reg 5 (bit 0x06400050) and always reads 0x08; the counter
runs in timer mode (ACR=0x60) with CTUR/CTLR never programmed, so MAME re-arms
at 1 tick and the interrupt re-asserts every ~229 CPU cycles. Frames at 3500 /
6000 / 12000 are byte-identical; RAM differs by one byte.
Corrects README.md and annotates GATE_CLEANUP_REPORT.md, BRINGUP_LOG.md and
DUART_REPORT.md. Adds a console+PC/milestone instrument and the finding report.
