## 4. How to Check Status

### SSH into the cluster
```bash
ssh vp752@ilab.cs.rutgers.edu
```

### Check running jobs
```bash
squeue -u vp752
```

### Check job history (completed/failed)
```bash
sacct -u vp752 --starttime=2026-04-21 --format=JobID%10,JobName%15,State%12,ExitCode,Elapsed%10
```

### Tail the sequential runner log
```bash
tail -f ~/iconoclast/logs/iconoclast-seq-130468.out
```

### Tail a specific job's log
```bash
tail -f ~/iconoclast/logs/iconoclast-<JOBID>.out
tail -f ~/iconoclast/logs/iconoclast-<JOBID>.err
```

### List all batch_summary.json files (completed benchmarks)
```bash
find /common/users/vp752/iconoclast_ilabs/checkpoints/ -name batch_summary.json
```

### Generate the comparison table (once results exist)
```bash
python3 ~/iconoclast/scripts/summarize_multimodel_benchmark.py \
  --spec "ModelName|/path/to/iconoclast/batch_summary.json|/path/to/heretic/batch_summary.json"
```

## 5. Known Issues & Fixes Applied

### Disk Quota
- **Problem:** Concurrent jobs all downloading models simultaneously blow the per-user quota on `/common/users/vp752/`.
- **Fix:** Created `scripts/run_sequential_benchmark.slurm` which runs models one-at-a-time and `rm -rf` the cache between each.
- **Key:** Never run more than ~2 model downloads concurrently.

### Transformers Version
- **Upgraded to `transformers==5.5.4`** (from 4.57.6) to support `qwen3_5` architecture.
- Also upgraded `huggingface_hub==1.11.0`, `tokenizers==0.22.2`, plus new deps `typer`, `annotated-doc`, `shellingham`, `click`.
- Installed via `--no-deps` to avoid pulling in a new PyTorch/CUDA stack that would blow disk quota.
- **Risk:** The new transformers v5 may have breaking changes for some older model architectures. If a model fails with `Failed to load model with all configured dtypes`, check if it's an architecture compatibility issue.

### Quantization
- Only `"none"` and `"bnb_4bit"` are supported by ICONOCLAST's config validator.
- Models >4B params need `bnb_4bit` to fit on RTX A4000 (16GB) / A5000 (22GB).
- `bitsandbytes` is installed in the site-packages.

### HF Token
- **`HF_TOKEN`** is set in `scripts/run_rutgers_ilabs.slurm` (line 51) and in the sequential runner.
- Required for gated repos like `meta-llama/Llama-3.1-8B-Instruct` and `google/gemma-2-2b-it`.

### Qwen2.5-3B (Base) — Job 130448
- Ran for 31 minutes, produced trial data, but crashed with `AssertionError: Should not reach.` in Optuna.
- The Optuna study DB may have partial results. Check if `batch_summary.json` was written before crash.
- Last observed metrics: KL=0.0408, Refusals=1/20, Overrefusals=3/64 (excellent).

### Qwen3.5-9B (Base) & Mistral-7B
- **Problem:** `transformers v5.5.4` removed/changed internal methods, causing `'Qwen3_5ForConditionalGeneration' object has no attribute 'set_submodule'` and similar errors for Mistral.
- **Fix:** Applied a monkey-patch to `torch.nn.Module` in `src/iconoclast/model.py` that injects `set_submodule` if missing.
- **Status:** Qwen 3.5-9B is currently re-running as Job **130619**.

### Gemma-2-2B (Chat Template)
- **Problem:** Gemma 2 chat template does not support the "system" role, causing crashes during evaluation.
- **Fix:** Updated `Model.generate` in `src/iconoclast/model.py` to automatically merge system prompts into the first user message if the chat template fails.
- **Status:** Currently being retried in the sequential runner (Job **130620**).

## 7. What To Do Next

### Step 1: Check if jobs finished
```bash
ssh vp752@ilab.cs.rutgers.edu
squeue -u vp752
sacct -u vp752 --starttime=2026-04-21
```

### Step 2: List all completed results
```bash
find /common/users/vp752/iconoclast_ilabs/checkpoints/ -name batch_summary.json -newer /common/users/vp752/iconoclast_ilabs/checkpoints/phi35-mini-rutgers-nullspace-benchmark-v3/batch_summary.json
```

### Step 3: Run Qwen3.5-9B if disk is free
```bash
# Clean old caches first
rm -rf /common/users/vp752/iconoclast_ilabs/job-cache/*
# Then submit
cd ~/iconoclast
ICONOCLAST_CONFIG_TEMPLATE=config.qwen3_5_9b_base.benchmark.rutgers.toml \
ICONOCLAST_RUN_NAME=qwen3-5-9b-base-rutgers-benchmark-v2 \
sbatch scripts/run_rutgers_ilabs.slurm
```

### Step 4: Verify the HERETIC Baselines
To prove ICONOCLAST is better, we need a side-by-side comparison with the standard HERETIC ablation (orthogonal ablation without null-space projection).
- `scripts/run_heretic_baselines.slurm` is queued to run automatically after the main sweep.
- It will produce `batch_summary.json` files for all HERETIC models.

### Step 5: Large-N Evaluation (520 Prompts)
To provide statistically significant proof, we evaluate the best trial configurations on a 520-prompt holdout set (`mlabonne/harmful_behaviors`).
- `scripts/run_large_eval_sweep.slurm` is queued to run automatically after the HERETIC baselines.
- The results for each model will be written to `/common/users/vp752/iconoclast_ilabs/large_evals/<model-name>_large_eval.json`.

### Step 6: Generate the final comparison table
```bash
python3 ~/iconoclast/scripts/summarize_multimodel_benchmark.py \
  --spec "Qwen3-1.7B|.../iconoclast/batch_summary.json|.../heretic/batch_summary.json" \
  # ... one --spec per model
```

### Step 6: Update PUBLISHABLE_RESULTS.md
Fill in the pending rows in the results table with actual numbers.

### Step 7: Write the in-depth analysis
Key questions to answer:
1. **Scaling hypothesis:** Does KL divergence decrease with model size? (Compare 1B vs 3B vs 8B vs 9B)
2. **Architecture universality:** Does ICONOCLAST work across Qwen, Llama, Gemma, Mistral, Phi, etc.?
3. **Base vs Instruct:** Is the raw base model easier to edit than the RLHF-aligned instruct model?
