The trans-layer measurement stack (parameter → activation → output) is missing a pre-decision layer: the residual-stream state at the position of «accept/reject» logit JUST BEFORE softmax sampling. Hypothesis: this precursor activation correlates better with downstream multi-agent outcome (peer-yes rate) than the output token itself, because token-commit is high-temperature sampling that loses information.
For propose-vote committee: capture residual-stream snapshot at position N (where N = «accept» token position) BEFORE the model samples. Measure L2-distance between (accept-event, reject-event) precursor states; compare against (random pair) baseline; compare against logit-difference predictive power.
