+# OpenSOC Defender — GRPO-trained LoRA adapter
+
+A **Qwen2.5-3B-Instruct** LoRA adapter (rank 16) trained via GRPO to triage Security Operations Center (SOC) alerts. Built for the [OpenEnv Hackathon, April 2026](https://huggingface.co/spaces/shivam2k3/opensoc-env).
+
+## Model Description
+
+- **Developed by:** Shivam Sharma
+- **Model type:** LoRA adapter (PEFT) for causal language model
+- **Language:** English
+- **License:** BSD-3-Clause
+- **Finetuned from:** [`unsloth/Qwen2.5-3B-Instruct`](https://huggingface.co/unsloth/Qwen2.5-3B-Instruct)
+
+## What it does
+
+Given a SIEM alert and a window of structured log events, the model chooses one of five SOC triage actions:
+
+| Action | Meaning |
+|---|---|
+| `dismiss` | Benign noise, no action needed |
+| `monitor` | Suspicious but not actionable yet |
+| `quarantine_host` | Isolate the endpoint |
+| `block_ip` | Block the external IP |
+| `escalate` | Wake a human — blast-radius event |
+
+The model also cites the specific `log_id` that drove its decision, which is verified against the env's ground truth for a +0.1 bonus reward.
+
+## Training
+
+### Training Data
+
+- **SFT warm-start:** 600 (alert, log_window → action + citation + rationale) gold examples generated by the OpenSOC environment's deterministic generator across all 4 curriculum stages.
+- **GRPO curriculum:** Online rollouts against the OpenSOC environment using verifier-grounded rewards.
+
+### Training Procedure
+
+1. **SFT warm-start** (~12 min on L4): Pushes P(format-compliant response) from ~0% to ~95%.
+2. **GRPO curriculum** (4 stages × 200 steps, ~3h on L4):
+   - `stage1_basic` — single-event, unambiguous templates
+   - `stage2_multi` — multi-event log windows, 1 decoy
+   - `stage3_mixed` — benign decoys interleaved with malicious events, 2 decoys
+   - `stage4_adversarial` — attacker-controlled distribution, 3 decoys
+
+### Training Hyperparameters
+
+- LoRA rank: 16
+- Learning rate (SFT): 2e-4
+- Learning rate (GRPO): 5e-6
+- GRPO group size (`num_generations`): 8
+- Batch size: 2 (with grad_accum=4)
+- Steps per stage: 200
+- Framework: Unsloth + HuggingFace TRL
+
+### Reward Design (RLVR)
+
+The reward is computed by a **deterministic verifier** — the ground-truth triage action is derived purely from the structured event parameters, never from any free text. This makes the reward verifiable and reproducible.
+
+**Defender reward components:**
+- +1.0 for matching the verifier's ground-truth action
+- −1.0 for dismiss-on-malicious (the cardinal SOC failure mode)
+- −0.3 for over-reacting on benign (containment on noise)
+- −0.05 for unnecessary escalation
+- +0.1 bonus for citing the correct triggering log_id
