Add the first boiler-upgrade option to the single "Heating & Hot Water" Recommendation (ADR-0024 expansion): a dwelling whose existing wet boiler heats a hot-water cylinder is offered a new gas condensing boiler, with the cylinder jacketed when under-insulated and given a thermostat when absent. One competing Option (the Optimiser picks <=1), folded into one composite Plan line. The end-state is read from the Elmhurst before/after re-lodgements (cert 001431, gas boiler upgrade - with cylinder), which REVISE ADR-0024: - Target is always a gas condensing boiler, not fuel-preserving: every after lodges fuel 26. Gas->gas always; a non-gas wet boiler ->gas only with a mains-gas connection; electric boilers are left alone (electrification is the upgrade path). Eligibility = wet-boiler SAP code (Table 4a/4b 101-141 / 151-161 / 191-196) + not an electric boiler + mains gas present. - End-state is a Table 4b SAP code, not a PCDB index: code 102 (regular boiler + cylinder). The calculator derives the condensing seasonal efficiency from the code, so no efficiency input exists or is needed. - A modern condensing boiler has a fanned flue: the after flips `fan_flue_present` False->True on every cert (SAP 10.2 Table 4f flue-fan + the Table 4b condensing-efficiency basis). Added as a new HeatingOverlay field, routed to main_heating_details[0]. - Cylinder thermostat is always added when absent (user-locked); the jacket is the 80 mm `cylinder_insulation_type=2` end-state, applied only when the cylinder is below 80 mm (never downgrading a better one). Both are conditional per-dwelling components, not a frozen overlay. Cascade-pinned delta-0 (SAP/CO2/PE) against the relodged after via `_assert_overlay_reproduces_after`. NB the absolute SAP on this dwelling is subject to a separate Summary-path mapper roof-fidelity gap (we read the roof better-insulated than Elmhurst, scoring ~75 vs the printed 56); the gap is identical on before+after (the boiler measure never touches the roof) so it cancels and the pin still proves the exact heating field-delta. Tracked on the calculator branch. Wires the new `gas_boiler_upgrade` MeasureType through contingencies (0.26), the offline sample catalogue, the catalogue-coverage list, and the ARA first-run integration seed (the option fires on any mains-gas boiler+cylinder dwelling).

Model Repository
This repository contains the code pertaining to the development of the data science and machine learning products being utilised by Hestia.
The different folders in this repository relate to services that can be used independently, or can be imported and used as part of a larger application
Getting Started
Prerequisites
Dev Container Setup
This repo uses a Docker Compose-based dev container. The model-backend service joins a shared-dev Docker network so it can communicate with other local services (e.g. a frontend container) running on your machine.
VS Code users: The initializeCommand in devcontainer.json creates the shared-dev network automatically before the container starts. No manual step required — just open the repo and select Reopen in Container.
Non-VS Code / CI workflows: Run the following once before starting the container:
make dev-setup
This is idempotent and safe to re-run if the network already exists.
Folders
backend/
This folder contains the code for the fastapi backend service, which provides an interface to much of the functionality in this repository, for the frontend
model_data/
This folder contains related to the reading and preparation of assessment model data, including pulling out epc attributes
Testing
All tests can be run, against the configuration in pytest.ini running
pytest
This will run the complete panel of tests and report on coverage in the locations specified by the pytest.ini file.
To run tests in a specific service, e.g. inside of model_data, simply run
pytest --cov-config=model_data/.coveragerc --cov=model_data
This will produce the test results and coverage reports
