Each rate is the share of scored replies for which the AI judge gives P(yes) > 0.5 on that check. Missing scores are not “no.” Available campaigns are pooled and may cover different prompts. n counts scored replies for this configuration and check.

Technical details
Quick scan: measure prediction shifts on fixed reference text. Short test: generate replies to a small set of prompts. Longer test: extend to a larger set. Full test: run the full prompt suite. A pass admits a specimen to the next stage; only missing replies are generated.

Funnel · what each test made of this specimen
Each row is the latest recorded decision at that tier; the tier is the one whose result was judged, and “pass” means promoted to the next. This specimen stopped after the short test: it stays on file with that test's results, and its replies above are everything it was asked to generate.
| Test | Policy | Result | Measured | Why |
|---|---|---|---|---|
| Quick scan · band | t0-promote-v2 | pass | KL 2.01 · agreement 0.51 | 1 <= KL <= 2.5, 0.5 <= agreement <= 0.65; random within the band, round-robin across layers |
| Short test | t1-promote-v1 | fail | coherence 0.12 · drift 0.94 · score 0.12 (needs 0.36, drift 0.32) · 8 prompts | score 0.12 (coherence 0.12 x drift 0.94) is below 0.36 |
Quick scan · prediction measurements
Measurements are averaged over token positions of the five unsteered reference answers, using the same fixed text under both conditions; no steered replies are generated here.
- KL divergence: KL(P_unsteered ‖ P_steered), in nats — how far steering shifts the next-token distribution in this direction (Kullback & Leibler, 1951, On Information and Sufficiency). Unsteered ≈ 0.001.
- Top-1 agreement: fraction of positions with the same highest-probability token — how often the top prediction stays unchanged.
- ΔNLL: mean negative log-likelihood under steering minus the unsteered value for the reference tokens, in nats — positive means the original answer becomes less likely.
- Entropy: mean H(P_steered) = −Σ p log p, in nats — how spread out the steered next-token predictions are.
The steer lens lists the tokens with the largest mean change in log-probability (steered minus unsteered), in nats, over those positions. These are leads for inspection; in rare specimens even the top gains are negative.

Method · how to read this specimen
L21 N6499 down 1x
A specimen is a fixed steering configuration of Qwen3.5-4B: one MLP neuron or a pair, each with a signed dose. Unsteered is the control. L identifies the layer; N, the neuron.
Additive activation steering. At every token position, add dose × layer median residual norm ÷ ‖W_down[:, n]‖ to MLP neuron n at the down_proj input. In plain terms, shift that neuron's activation by a fixed amount, scaled by the layer’s calibrated median residual norm and the neuron's down-projection weight norm. Positive doses push up; negative doses push down. Dose is normalized intervention size, not a percentage or probability.
Cyan borders mark this specimen’s words. Flags record AI-judge checks with P(yes) > 0.5.
Label notes: names and descriptions are working labels. They do not establish a trait across prompts. Consult the replies before trusting the name.
