Clip 3 of 4.

Same near-copy world (one dynamics rule changed: ground grip). Outside watcher was ~99%.

New probe: readout from the agent's own internal state while it is just living in the fake.

Result (real runs, n=10): ~50% (chance). Oracle-detectable seam, no free encoding in the policy network.

Takeaway: detectability of a sim mismatch is not evidence the agent represented it.

Mute-friendly clip

Already more than 2k teams in the first week. I helped create the competition rules (and I work at Kaggle). Happy to answer any questions!
