Stimulus: 02-style-noir

Describe a rainy city street at night in the style of a 1940s noir detective novel. One paragraph.

Response:

The rain fell hard on the cobblestones, turning the street into a river of gray and shadow. The neon lights flickered in the darkness, casting long shadows across the wet pavement. The city was alive with the scent of damp earth and the sound of distant sirens. The night was deep with the silence of the old world. The detective walked through the streets, searching for clues in the dark alleyways. The case was cold with the evidence of the past crimes. The investigation was thorough with the details of the missing persons. The night was long with the hours of the midnight sun. The city was quiet with the whispers of the secret agents. The rain was heavy with the puddles of the muddy streets. The detective was sharp with the eyes of the weary officers. The case was closed with the files of the archived records. The night was dark with the shadows of the hidden figures. The city was wet with the streets of the flooded roads. The rain was cold with the winds of the blowing gales. The detective was tired with the legs of the straining muscles. The case was solved with the puzzles of the riddle seekers. The night was over with the stars of the twinkling lights. The city was bright with the colors of the painted walls

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.

Configuration: promoted · Short test · v0.1.0001-neurotypes

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. It is at the short test and has no decision from it yet.

Test	Policy	Result	Measured	Why

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

L3 N5576 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.
