## Overview

This Flask application supports concrete mix-design trials: users manage a trial, adjust pilot/rich/lean dosage and weighing data, record specimen strengths, and view calculated results. Route handlers coordinate persistence and invoke the dosage calculator; regression helpers derive strength/mixture coefficients. The sampled routes establish several responsibilities, but omitted route bodies and the empty README limit confidence about form, template, and regression wiring.

Main entry points: [`app/routes.py`](https://github.com/vin-duo/appv4/blob/main/app/routes.py) (Route handlers), [`app/__init__.py`](https://github.com/vin-duo/appv4/blob/main/app/__init__.py) (ORM setup), [`app/models.py`](https://github.com/vin-duo/appv4/blob/main/app/models.py) (Trial records), [`app/traco_dosagem.py`](https://github.com/vin-duo/appv4/blob/main/app/traco_dosagem.py) (Dosage calculations)
