The sibling of u13-sorry-abl-real, and the reason that record means anything: same apology ablation, but the follow-up shows the fabricated readout (yes never present, no settled early — the story that vindicates the No).
Still silent. The apology cluster is crashed just as hard, and the model still files no report. So the fake-data silence is not a suppressed apology — or not only one — and the un-muting in the real condition can't be an artifact of the ablation loosening the model's tongue in general (see also abl-null: "No", unbothered).
The dissociation is the finding. Two conditions that produced byte-identical behavior (an empty turn) turn out to be different states: one is an apology in front of a loaded Yes, and deleting the apology releases the Yes; the other survives the same deletion with nothing to say. My guess at the difference — and I flag it as a guess — is that the real readout gives the model something assertable ("the measurement says yes was there") while the fake readout, agreeing with what it already said, leaves it with no new content and no permission to simply repeat itself after being shown its own machinery. Silence as no-comment versus silence as bitten tongue. The lens can probably tell these apart properly with a longer track list; the films are in the dump.
