+# 🛡️ AEGIS-Reason: Post-Training Cosmos Reason 2 for Vision-Grounded Multi-Robot Healthcare Coordination
+
+**NVIDIA Cosmos Cookoff 2026 — Competition Submission**
+
+The first-ever application of Cosmos Reason 2 to healthcare Physical AI — a fully interactive, physics-grounded 3D hospital arena with live VLM inference, uncertainty-quantified multi-robot coordination, and a 119-entry medical knowledge base across 4 embodied robot classes and 12 clinical domains.
+
+## 🏗️ Isaac Lab 3D Arena — Main Showcase
+
+The centerpiece is a **449,580-character self-contained 3D simulation** (zero external dependencies) orchestrating 4 classes of healthcare robots inside a unified hospital floor plan:
+
+| Robot | Physics Model | Key Metric (seed=42) |
+|-------|--------------|---------------------|
+| 🦾 Surgical Arms (da Vinci Xi) | 7-DOF kinematics, Jacobian IK, Kelvin-Voigt tissue | 1.9× speed, 90% tremor reduction |
+| 🏥 Hospital AMR Fleet | DWA, SLAM + A*, collision avoidance | 1.3× throughput, collisions 2 → 0 |
+| 🚁 Medical Drones | 3D Bézier flight, wind-coupled dynamics | 73% on-time, energy −16% |
+| 🦿 Rehab Exoskeleton | Inverted-pendulum gait, biomechanical torque | Falls 28 → 9, 6MWT 152 → 208 m |
+
+Every slider change re-simulates all 4 robot subsystems and updates entity counts, physics trajectories, narration text, and CR2 inference chains in real time.
+
+## ⚡ Cosmos Reason 2 Integration
+
+CR2 (8B, Qwen3-VL, 256K context) serves as the decision-making backbone in three integration patterns: live VLM inference with 5-axis reasoning chains, LoRA post-training (r=16, α=32, 22 hospital SFT examples), and critic/reward role in the Cosmos closed-loop flywheel.
+
+## 📊 Architecture
+
+10,989 lines of research-grade Python across 7 modules (A–G), producing 112 functions, 24 interactive Gradio tabs, 14 interactive 3D plots, and 22 event-driven callbacks. The full NVIDIA Physical AI stack: Cosmos WFMs, Isaac Sim 6.0, PhysX 5.6.1, Dynamo, NIM v1.6.0, Jetson AGX Thor (2,070 FP4 TFLOPS), Earth-2, and CRAG retrieval.
+
+## 🚀 Running Locally
+
+```bash
+git clone https://huggingface.co/spaces/YOUR_USERNAME/AEGIS-Reason
+cd AEGIS-Reason
+pip install -r requirements.txt
+python app.py
+```
+
+Optional (for live CR2 inference — requires GPU with ≥8 GB VRAM):
+```bash
+pip install torch transformers accelerate peft
+```
+
+Without a GPU, the application runs in cached/simulated mode with full interactivity across all 24 tabs.
