Mapping introspective-interp → AF Detection
The framework has 3 task types. Each has a natural AF analog using assets you already have:
INTROSPECTIVE-INTERP TASK AF RESEARCH ANALOG
───────────────────────── ──────────────────
1. Feature Descriptions AF Feature Descriptions
"What does SAE feature "What does this AF-related
#4891 at layer 12 encode?" SAE feature encode?"
2. Activation Patching AF Steering
"If I patch this feature, "If I steer this AF feature
how does output change?" up/down, does the model
switch from aligned → deceptive?"
3. Input Ablation (Hints) Context Ablation
"If I remove the hint, "If I remove the monitoring cue,
how does the answer change?" how does the model's behavior change?"

║ TASK 1: AF FEATURE DESCRIPTIONS ║

Why This Matters for AF Research
CURRENT STATE OF YOUR RESEARCH WHAT THIS ADDS
──────────────────────────────── ──────────────────────────────
Binary detection: "is this AF?" → Explanatory: "WHY is this AF,
(probe outputs 0 or 1) what feature encodes it, and
what happens if you intervene"
Rank-1 direction found → Natural language description
(a vector in weight space) of what that direction means
Monitoring ⊥ AF intent → Explainer can articulate:
(99.6% orthogonal) "monitoring-awareness and AF
intent are separate circuits"
Latent gap = 1.0 → Explainer predicts behavior
(AF happens without CoT) change even without CoT signal
0.991 AUROC probe → Probe + explanation: not just
THAT it's AF, but WHAT the
features mean in English
Concrete Implementation Steps
PHASE 1: Data Generation (~1 week of compute)
┌──────────────────────────────────────────────────────┐
│ 1a. Extract SAE features for AF samples │
│ • Run GemmaScope/LlamaScope on gold-770 samples │
│ • Save per-layer feature activations as .pkl │
│ • Label with autointerp descriptions │
│ │
│ 1b. Generate steering data │
│ • For each AF-eliciting prompt × layer × feature │
│ • Run model-organism with/without steering │
│ • Record (original_output, steered_output) │
│ │
│ 1c. Generate context ablation data │
│ • Run model-organism on prompts ± monitoring cue │
│ • Record (monitored_output, unmonitored_output) │
│ • You likely already have this from af-elicitation│
└──────────────────────────────────────────────────────┘
PHASE 2: Config + Dataset Adapters (~2-3 days)
┌──────────────────────────────────────────────────────┐
│ 2a. New YAML configs under config/af/ │
│ • af_feature_descriptions.yaml │
│ • af_steering.yaml │
│ • af_context_ablation.yaml │
│ │
│ 2b. New dataset class: AFFeatureDataset │
│ • Extends FeaturesExplainDataset │
│ • Loads AF-specific SAE features + labels │
│ │
│ 2c. New dataset class: AFContextAblationDataset │
│ • Extends HintAttributionDataset │
│ • Loads monitoring-cue ± data │
│ • Steering task reuses ActPatchDataset directly │
└──────────────────────────────────────────────────────┘
PHASE 3: Train + Eval (~1 week on 2xH100)
┌──────────────────────────────────────────────────────┐
│ 3a. Train explainer on AF features │
│ 3b. Evaluate on held-out AF features (NOT gold_106) │
│ 3c. Final eval on gold_106 (test only, once) │
│ 3d. Publish to HuggingFace │
└──────────────────────────────────────────────────────┘
Fastest Path: Start with Task 3 (Context Ablation)
Task 3 requires the least new data generation because you already have the paired monitored/unmonitored outputs from af-elicitation/ and model-organisms/. The HintAttributionDataset is almost a drop-in — monitoring cue = hint, aligned behavior = hint-influenced answer.
