+# SMS Spam Classifier - DistilBERT ONNX Pipeline
+
+## Overview
+
+This directory contains the training pipeline for a fine-tuned DistilBERT SMS spam classifier, exported to ONNX format for fast CPU inference in the Kordant spamshield service.
+
+## Architecture

+
+## Training
+
+### Prerequisites
+
+- Python 3.10+ (tested with 3.14)
+- Virtual environment: `python3 -m venv .venv-ml && source .venv-ml/bin/activate`
+- Dependencies: `pip install transformers datasets torch optimum[onnxruntime] onnxruntime`
+
+### Run Training
+
+```bash
+# Full pipeline with data augmentation
+python ml/spam-classifier/train.py \
+  --output-dir ml/spam-classifier/output \
+  --augment \
+  --epochs 3 \
+  --batch-size 32
+
+# Skip training (use existing model for export only)
+python ml/spam-classifier/train.py \
+  --output-dir ml/spam-classifier/output \
+  --skip-training
+
+# With INT8 quantization
+python ml/spam-classifier/train.py \
+  --output-dir ml/spam-classifier/output \
+  --augment \
+  --quantize
+```
+
+### Training Parameters
+
+| Parameter | Default | Description |
+|-----------|---------|-------------|
+| `--epochs` | 3 | Number of training epochs |
+| `--batch-size` | 32 | Training batch size |
+| `--lr` | 2e-5 | Learning rate |
+| `--augment` | false | Include synthetic data augmentation |
+| `--quantize` | false | Quantize to INT8 for smaller model |
+| `--skip-training` | false | Skip training, only export |
+
+### Expected Results
+
+- **Validation accuracy**: 97-99% on SMS Spam Collection
+- **Training time**: ~5-10 minutes on M-series Mac, ~2-3 minutes on GPU
+- **Model size**: ~257MB (FP32), ~128MB (INT8 quantized)
+
+## Inference
+
+### Setup
+
+The trained ONNX model is deployed to `web/src/server/models/spam-classifier/`.
+
+The Node.js inference wrapper is in `web/src/server/services/spamshield/onnx.inference.ts`.
+
+### Usage
+
+```typescript
+import { classifyTextBERT, initSpamModel } from "~/server/services/spamshield/onnx.inference";
+
+// Initialize at startup (loads model once)
+await initSpamModel();
+
+// Classify text
+const result = await classifyTextBERT("Hello world");
+// { isSpam: false, confidence: 0.97, score: 0.03, modelVersion: "1.0.0" }
+
+// With threshold mode
+const strict = await classifyTextBERT("Get free money!", "strict");
+const lenient = await classifyTextBERT("Get free money!", "lenient");
+```
+
+### Threshold Modes
+
+| Mode | Threshold | Description |
+|------|-----------|-------------|
+| `strict` | 0.3 | Aggressive spam detection, more false positives |
+| `moderate` | 0.5 | Balanced (default) |
+| `lenient` | 0.7 | Conservative, fewer false positives |
+
+### Performance
+
+| Metric | Value |
+|--------|-------|
+| p50 latency | <5ms |
+| p95 latency | <30ms |
+| p99 latency | <50ms |
+| Throughput | ~240 inferences/sec |
+| Model load time | ~2s (cold start) |
+
+### Benchmark
+
+```bash
+cd web
+pnpm benchmark:spamshield --iterations 1000
+```
+
+## Model Versioning
+
+The model version is tracked in `model_metadata.json` alongside the ONNX files.
+
+To deploy a new model:
+1. Run training with new data/hyperparameters
+2. Update version in `model_metadata.json`
+3. Copy ONNX files to `web/src/server/models/spam-classifier/`
+4. Deploy
+
+## Feedback Loop
+
+User feedback is stored in the `spam_feedback` database table and can be used for periodic retraining:
+
+```sql
+SELECT text, is_spam, feedback_type FROM spam_feedback
+WHERE feedback_type = 'user_rejection'
+ORDER BY created_at DESC;
+```
