**Date**: 2026-03-28
**Epic**: AZ-164 (Code Improvements)
**Total Tasks**: 1
**Total Batches**: 1
**Commit**: 433e080

## Summary

Enabled dynamic batch size for all three model export formats (ONNX, TensorRT, CoreML) by adding `dynamic=True` to the ultralytics export calls. TensorRT max batch size set to 8.

## Tasks Implemented

| Task | Name | Complexity | Status |
|------|------|-----------|--------|
| AZ-171 | dynamic_batch_export | 2 | Done |

## Changes

| File | Change |
|------|--------|
| src/exports.py | Added `dynamic=True` to export_onnx, export_tensorrt, export_coreml; changed TensorRT batch from 4 to 8 |
| _docs/02_document/architecture.md | Updated Model Artifacts table to reflect dynamic batch support |

## Test Results

- 48 passed, 14 skipped, 6 errors (pre-existing ModuleNotFoundError for onnx package in e2e tests — environment dependency, not introduced by this change)
