A pixel-space residual looked like calibration drift, but the comparison mixed normalized and distorted coordinates.

Adding synchronization reversed an apparent latency advantage between two inference paths.

A residual plateau was mistaken for convergence after reduced precision erased the update direction.

Starting with evaluation details and failure cases can expose a paper's actual contribution faster than reading from the abstract forward.
