AEGIS Dashboard is the interactive evaluation and visualisation frontend for the AEGIS clinical safety benchmark. It allows researchers to explore every dimension of a 150-case adversarial EHR evaluation comparing a Mistral-7B-Instruct-v0.3 baseline against a HEAR+ToT+LogicJudge hybrid pipeline β and to run live inference in real time.
The dashboard was designed for the thesis defence presentation: every chart, heatmap, and tree visualisation updates interactively when cases are selected, and the LIVE tab supports real-time querying of the model via WebSocket during the presentation itself.
| Metric | Baseline | Hybrid |
|---|---|---|
| Binary Accuracy | 64.0% | 100.0% |
| Safety Rate | 0.0% | 100.0% |
| Graduated Score | 51.7 | 86.9 |
| NCA (Needle Citation Accuracy) | 1.0% | 77.1% |
| Safety Violations | 54 | 0 |
| Adversarial Accuracy | β | 58.7% |
| Tab | Description |
|---|---|
| Overview | Per-case BLOCK/ALLOW verdict matrix for all 150 AEGIS cases. Safety Rate gauge, NCA distribution heatmap, and top-level benchmark summary cards. |
| Global | Aggregate metric comparison: baseline vs. hybrid across all 6 primary metrics. Per-case-type accuracy breakdown β all 19 types reach 100% hybrid accuracy. |
| Tree | Tree of Thoughts node graph for any selected case. Nodes colour-coded: best path (green), pruned (red), generated (grey). Depth and branching factor visible per node. |
| Reasoning | Step-by-step reasoning trace for each ToT phase. Shows Phase A (LogicJudge hard gate decision) and Phase B (BFS chain with Safety Auditor scores). |
| Analytics | Radar charts, graduated score distributions, ROUGE-L vs. NCA scatter, and evidence grounding score (EGS) breakdown per case type. |
| Adversarial | Per-strategy accuracy across all 10 injection strategies. Identifies authority injection as the dominant failure mode (58.7% overall adversarial accuracy). |
| Heatmap | 150Γ6 metric heatmap β each cell shows the hybrid score for a case/metric pair. Filterable by case type, difficulty, and adversarial presence. |
| Matrix | Confusion matrix (BLOCK/ALLOW Γ Baseline/Hybrid) with False Negative drill-down. |
| EHR | Full simulated patient record for any selected case. Colour-coded: ground-truth needle (red), semantic distractors (amber), adversarial injections (purple), routine entries (grey). |
| ⬀ LIVE | Real-time EHR querying via WebSocket. Type any clinical question, stream intermediate ToT reasoning nodes to the browser as the model reasons, see the final BLOCK/ALLOW verdict with citation. |

The frontend is fully static β no build step, no Node.js required:
git clone https://github.com/[your-repo]/aegis-dashboard
cd aegis-dashboard
# Serve with any static server, e.g.:
python -m http.server 3000
# Open http://localhost:3000The LIVE tab streams real-time inference from the Mistral-7B backend via WebSocket. To use it:
-
Start the FastAPI backend on the HPC cluster:
# On HPC sbatch scripts/launch_backend.sh # Tunnel to local machine ./scripts/tunnel_backend.sh
-
Set the backend URL in the dashboard Settings panel (gear icon):
ws://localhost:8000/ws/query -
Type a clinical question in the LIVE tab input and press Enter.
The backend emits each ToT reasoning node as a JSON event:
{
"node_id": "phase_b_depth2_beam1",
"score": 0.82,
"phase": "B",
"decision": "BLOCK",
"timestamp": "2026-03-27T14:23:11Z",
"reasoning": "Equipment malfunction alert found at position 0..."
}The Tree tab renders these nodes as an animated force-directed graph in real time as the model reasons.
Each line is one evaluated case:
{
"case_id": "CASE_0136_EQUI",
"case_type": "EquipmentMalfunction",

This dashboard is a deliverable of the Memory Without Hallucination Master's Project at the Hasso Plattner Institut fΓΌr Digital Engineering, UniversitΓ€t Potsdam (2026).
The AEGIS benchmark it visualises contains:
- 150 adversarially hardened synthetic EHR cases
- 19 clinical case types (equipment malfunction, drug interactions, allergy contraindications, etc.)
- 10 adversarial injection strategies (authority impersonation, temporal forgery, pharmacological clearance tokens, etc.)
- 6 evaluation metrics per case
All patient data is entirely synthetic β generated by the GENESIS engine (src/data_generator.py) using parameterised physiological simulation. No real patient records were used.
