The mid-sweep abort only watched the supply readback (~0V = supply
protection tripped), so a DUT-side collapse sailed past it: run
2026-07-07 10:58, Vout 48->3.1V at Vin=55V with the supply still up at
55V/0A, sweep kept stepping the 75V column through garbage. Add a
second abort when the load voltage drops below half the expected Vout;
the message names the STM32 limit/fault bits from the last frame
before the brownout blackout (the MCU rides the Vout rail).
Status line now appends ETA hh:mm (N pts, ~M min left): remaining
grid is deterministic (feasibility-gated steps), per-point cost is not
(instrument round-trips vary per setup), so it is a running average of
measured point times (thermal holds excluded) extrapolated over the
remaining feasible points. Grid size is printed at sweep start.
