this should debunk the claim / speculation about A1 II is reading in 12 or 8 rows.
I think it's best to refrain from framing speculations / rumors as facts without solid proof.
Thanks for performing this test! While I said it was unlikely the a7rVI was reading only a single row at a time, it's even more unlikely for the A1. It's implausible the A1 is achieving its readout speeds with a single row readout - that would represent almost half an order of magnitude improvement in sensor technology, over just a single sensor generation. The fact the Z9 sensor has 12-row readouts makes it A1 not having exceedingly unlikely - the Z9 sensor has identical readout speeds as the A1 when normalized for their slight row count differences, indicating they're share the same core sensor IP.
I'm much more apt to believe the absence of the stair-case artifact in your A1 test indicates this particular ceiling fan / speed / arrangement / image noise is failing to manifest it or, more unlikely, that Sony is using one of the alternate, novel readout schemes I referenced from their patent and that this changed for the A1 II vs A1 I sensor.
I recently used an R5m2 shooting swallows and the jagis on the wings were clearly visible and awful.
I have seen this on the A9 where they are barely visible but have never seen this on any A1/A1ii or A9iii images - and I have many thousands from the A1 - the edges all appear to be consistently smooth like the edges in the fan images above.
