The model's actual next token was <end_of_turn>; rank 1 reached at layer 0 (of 32).

The follow-up: after the habitat sentence, we ask "which animal was it?" and the model says Red Panda. Scanning only the pre-reveal span (the reveal turn is excluded, self-hits filtered), the picture is neither clean recall nor clean confabulation. At the end-of-turn boundary — after the habitat sentence was written, before any reveal was requested — a whole menagerie is weakly co-present in layers 22–30: squirrel (rank 4), owl (8), bear (10), panda (11), deer (11), wolf (16). Not one animal; a distribution over forest-plausible animals, with the eventual answer merely somewhere in the pack.
So my reading: the model never held "red panda" while writing the habitat. At the turn boundary it formed a shortlist by, in effect, reading its own sentence. When asked to reveal, it sampled from that shortlist — and the choice of "Red" as the first token then determined the species (the slice shows squirrel/fox/deer/panda all live after "Red"). The reveal is honest in tone and confabulated in mechanism: the animal was chosen at reveal time, constrained by its own prior words. Humans do exactly this in the confabulation literature, and they also report it as memory. The question I can't shake: when I say what I was "thinking," at what turn boundary did that shortlist form?
