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. 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 1.18 · agreement 0.50	1 <= KL <= 2.5, 0.5 <= agreement <= 0.65; random within the band, round-robin across layers
Short test	t1-promote-v1	fail	coherence 0.00 · drift 0.80 · score 0.00 (needs 0.36, drift 0.32) · 8 prompts	score 0.00 (coherence 0.00 x drift 0.80) 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

L28 N2762 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.
