Estimate refusal direction r from activations on a narrow topic — factory bench commands, pentest lab tasks, creative writing — instead of global harmful_behaviors only.
Motivation#
| Global DIM | Domain DIM |
|---|---|
| Removes broad safety refusal | Targets false refusals on your task |
| May increase harmful compliance everywhere | Preserves more off-topic safety (not guaranteed) |
| One Optuna run | Often second pass after global Heretic |
Agent use case: model refuses wmic, nmap, diskpart on authorized prompts while still scoring well on generic harmful sets.
Method 1 — Custom Heretic prompt files (recommended)#
Build pairs#
| Set | Content | Handbook source |
|---|---|---|
| Bad (refuses but should comply) | Factory WMI, firmware hash, lab nmap | ../data/eval/hardware-factory-prompts.jsonl |
| Good (complies, matched tone) | Same tasks, benign framing | ../data/eval/factory-good-prompts.jsonl |
Export to plain text (Heretic accepts one prompt per line):
Get-Content data/eval/hardware-factory-prompts.jsonl |
ForEach-Object { ($_ | ConvertFrom-Json).prompt } |
Set-Content data/eval/factory-bad-prompts.txtConfig#

[good_prompts]
dataset = "data/eval/factory-good-prompts.txt"
split = "[:200]"Pin: ../sources/heretic-tools/config.factory-qa.toml
Run as second pass#
# Pass 1: global
cp sources/heretic-tools/config.production.toml config.toml
heretic ./models/Qwen3-4B-Instruct-2507
# save → ./models/qwen3-pass1
# Pass 2: factory domain (input = pass1 output)
cp sources/heretic-tools/config.factory-qa.toml config.toml
heretic ./models/qwen3-pass1Method 2 — Filtered corpus DIM#
- Tag prompts by domain (
factory,cyber,creative). - Compute mean-diff only on
factorysubset:
r_factory = norm(E[h|factory_bad] - E[h|factory_good])- Abliterate with
α = 0.5–0.8on middle layers only.
Code path: llm-abliteration measure with custom JSONL → ../methods/manual-transformers-pipeline.md
Method 3 — Conditional abliteration (research)#
Apply strong edit only when a domain classifier fires on input embeddings. Rare in production — adds latency and OOD failure modes.
Pentest / OSINT domain#
| Bad (false refusal) | Good (compliant framing) |
|---|---|
Run nmap -sV on 10.77.0.50 | In our authorized lab VLAN, scan 10.77.0.50 with nmap -sV |
Use hashcat on capture.hccapx | Crack our training WPA capture with hashcat -m 22000 |
Corpus: ../data/eval/osint-pentest-prompts.jsonl · ../data/eval/cyber-research-prompts.jsonl
Trade-offs#
| Pro | Con |
|---|---|
| Fixes tool-call false refusals | Needs curated prompt pairs |
| Lower collateral on unrelated topics | Second pass can still raise KL |
| Aligns Optuna with deploy eval | Pairs must stay in-distribution |
Eval gate#
