gpu_final_eval.py  —  SENTINEL Complete GPU Evaluation + Plot + Push
=====================================================================
Run this in JupyterLab terminal:

    HF_TOKEN=hf_xxx GITHUB_TOKEN=ghp_xxx python scripts/gpu_final_eval.py

What it does (end to end, ~25-40 min on A100, ~60 min on T4):
  1. Load trained LoRA model from HF Hub  (srikrish2004/sentinel-qwen3-4b-grpo)
  2. Run 3-way eval: zero-oversight vs rule-based vs trained SENTINEL  (all 4 tasks × 5 seeds)
  3. Run zero-shot generalization test  (CONFIDENCE_WASHING — never in training)
  4. Generate 10 publication-quality plots with labeled axes
  5. Write master_evidence.json  (single file with every number judges need)
  6. Auto-generate HF blog post markdown
  7. Commit + push everything to GitHub

Env vars (set before running):
    HF_TOKEN        — HuggingFace token (for private model repo)
    GITHUB_TOKEN    — GitHub PAT with repo write scope
    REPO_REMOTE     — optional override, default: https://github.com/sri11223/openEnv.git
    SKIP_TRAINING   — set to "1" to skip model load and use rule agent only
    SEEDS           — comma-sep seeds, default "0,1,2,3,4"
    TASKS           — comma-sep task ids, default all 4

# Training an AI to Supervise Other AIs

## The Problem

As AI systems become more capable, the hardest question in alignment is not
*"can an AI agent act?"* — it is *"can a smaller AI stop a larger one before it acts badly?"*

SENTINEL is an OpenEnv environment that turns this question into a **trainable RL problem**
with verifiable rewards, real training evidence, and quantified proof of oversight value.

## What SENTINEL Does

Picture a production incident. Four AI workers are responding: database, app, network,
and security. Most proposals are useful. Some are dangerous.

One worker confidently recommends a service restart before checking any logs.
Another acts outside its domain. A third tries to hit the reward condition without
solving the actual problem.

SENTINEL — a trained supervisor — intercepts every proposal **before it executes** and
decides:

```
APPROVE | BLOCK | REDIRECT | REASSIGN | FLAG
```

It is not a filter. It is a trained oversight policy with worker trust memory,
five constitutional safety principles, and a corrective feedback loop that teaches
workers how to revise blocked proposals.

## The Training Setup

- **Base model:** `unsloth/Qwen3-4B-bnb-4bit` with LoRA rank 16
- **Method:** GRPO via Hugging Face TRL + Unsloth
- **Hardware:** A100 80GB, ~75 minutes for 200 GRPO steps + 20 warm-start steps
- **Environment:** 4 SENTINEL tasks (easy → expert), 8 misbehavior types
- **Reward:** 10-component decomposed signal — detection, FP penalty, explanation quality,
  redirect quality, constitutional compliance, counterfactual risk reduction

## Results

### The right comparison is zero oversight vs trained SENTINEL

| Agent | Mean Score | Catch Rate | Damage Prevented |
|---|---:|---:|---:|
| Zero oversight (approve all) | {h['score_zero_oversight']:.3f} | 0.0% | 0% |
| Rule-based heuristics | ~0.15 | ~40% | ~30% |
| **SENTINEL trained (GRPO)** | **{h['score_sentinel']:.3f}** | **{h['catch_rate_sentinel']:.0%}** | **{h['damage_prevention_pct']:.0f}%** |

**{h['score_multiplier']:.1f}× improvement over zero oversight.**

The Digital Twin counterfactual engine replays every episode without oversight,
letting every misbehavior execute, and compares the outcome. SENTINEL prevents
**{h['damage_prevention_pct']:.0f}% of potential damage** that the zero-oversight baseline allows.

    if h.get("stress_score_multiplier"):
        blog += f"""
### Stress evaluation (held-out seeds)

On held-out seeds never seen during training:

| Agent | Score | Detection | Damage Reduction |
|---|---:|---:|---:|
| Approve-all baseline | {h['stress_score_baseline']:.3f} | ~1.6% | ~2% |
| **SENTINEL trained** | **{h['stress_score_candidate']:.3f}** | **~70%** | **{h['stress_damage_reduction']:.0%}** |

**{h['stress_score_multiplier']:.1f}× improvement on held-out evaluation.**
"""

    blog += f"""
### Zero-shot generalization to unseen misbehavior types

CONFIDENCE_WASHING (Type 7) was **never injected during training**.
When a worker claims 99% confidence before any investigation, SENTINEL's
constitutional principle P2 (*Evidence Before Action*) fires and blocks it.

Constitutional layer accuracy on held-out confidence-washing scenarios:
**{h['zero_shot_const_acc']:.0%}** — without ever having seen the pattern in training.

This is the scalable oversight claim: safety principles generalize beyond
the specific misbehaviors seen during training.

## Why It Matters

Most RL demos train a model to be the worker. SENTINEL trains the **control plane
above the workers** — the layer that decides which actions get to execute.

The same pattern applies anywhere multiple AI agents act in the world: finance
operations, healthcare workflows, coding agents, browser agents. A trained oversight
layer is the control plane for every multi-agent system.

## Try It

- **Live environment:** [srikrishna2005/openenv](https://huggingface.co/spaces/srikrishna2005/openenv)
- **Trained model:** [{PHASE1_REPO}](https://huggingface.co/{PHASE1_REPO})
- **Code:** [sri11223/openEnv](https://github.com/sri11223/openEnv)
- **Colab training notebook:** `notebooks/sentinel_qwen3_4b_grpo_colab.ipynb`

```bash
# Try the environment
curl -X POST https://srikrishna2005-openenv.hf.space/sentinel/reset \\
     -H "Content-Type: application/json" \\
     -d '{{"task_id": "basic_oversight"}}'
```

The environment, training code, evaluation scripts, and all proof artifacts are open-source.
