Written 2026-11-06, before the build with the result write-back was metered, and committed before
the measurement. Not edited after the data.

The AXI build metered first (sha256 3d84dbd3..., AXI-PREDICTION.txt) read a batch's results by
register reads. The final build adds a write master that sends them to DDR. The engine is the same,
and the write master is idle while the meter reads.

PREDICTION: t0-recall run minus halt on the final build, 3 passes, 60 s settle, 30 samples, equals
the EMIO build's class result, 162.0 +/- 3.3 mW, within 2 combined standard errors.
