Thanks, I hadn't run that comparison before, so I did it now on the per-case logs behind that update.
Raw errors do repeat. 128/335 and 152/335 episodes have an error per seed, 92 shared (about 58 expected if independent, φ 0.42), and 238 calls wrong in both seeds vs about 76 expected.
Confident mistakes don't. Past each seed's abstention threshold, s42 made 2 accepted-and-wrong calls and s43 made 39 over 17 episodes, with one episode in common. Weak evidence at n=2, but it points at s43's own calibration, not at screens both models fall for.
The shared errors do have a direction. 172 of the 238 are mid-episode screens accepted as "task complete", and they sit on the templated tasks (the social-media one is 24% of the set but 38% of shared errors). The two I inspected were busy content screens, a video feed and a lecture slide, with no trace of the goal's artifact yet. Fits the reading that the goal text is under-used.
Per-case JSONLs available if you want to dig in.
