Closes 23 of 24 mapper-vs-hand-built load-bearing divergences by
populating fields the Elmhurst mapper extracts from Summary_000477.
pdf but the original cohort hand-built left at their `make_minimal_
sap10_epc` / dataclass-default values. Every change is cascade-
equivalent — none alter `_FIXTURE_PINS["000477"]` SapResult fields
(all 11 1e-4 pins remain GREEN against worksheet `SAP value 65.0057`).
Mirrors the Slice 64 pattern on the cohort 000474 hand-built:
SapBuildingPart additions (Main only — 000477 is a single-bp mid-
terrace, no extension):
- `wall_thickness_measured`: False → True. Summary §7 lodges Wall
Thickness 380 mm explicitly; the cascade doesn't consume this flag.
- `floor_type`, `floor_construction_type`, `floor_insulation_type_
str`, `floor_u_value_known`: surfaced from Summary §9 ("G Ground
floor" / "T Suspended timber" / "A As built" / U-value Known = No).
Cascade reads the int codes on SapFloorDimension, not these strings.
- `roof_insulation_location="Joists"`: surfaced from Summary §8.
SapVentilation additions (all cascade-equivalent — `None` defaults to
0 throughout the §2 cascade chain):
- 6 explicit zero counts (`open_flues`, `closed_flues`, `boiler_
flues`, `other_flues`, `passive_vents`, `flueless_gas_fires`)
- `pressure_test="Not available"` (descriptive — cert lodges no test)
- `draught_lobby=True` (legacy field; cascade reads `has_draught_
lobby=False` which stays as set)
Top-level additions via `make_minimal_sap10_epc`:
- `blocked_chimneys_count=0`, `dwelling_type="Mid-Terrace house"`,
`built_form="Mid-Terrace"`, `property_type="House"`
Post-construction mutations (helper doesn't expose these as kwargs):
- `has_conservatory=False`, `any_unheated_rooms=False`,
`number_of_storeys=3` (cohort 000477 has ground + first + RIR)
- `sap_heating.shower_outlets=ShowerOutlets(Non-electric shower)`
- `sap_heating.main_heating_details[0].central_heating_pump_age_str=
"Unknown"`
Diff count: 24 → **1**. The remaining diff is structural:
- `sap_windows: LEN 7 vs 3` — mapper extracts 1:1 from §11 table;
the hand-built collapses by glazing-type group, preserving total
area. Cascade-equivalent but not field-equal. Closes via the same
1:1 expansion that Slice 69 applied to cohort 000474 (5 → 7).
11 cohort 000477 cascade pins still GREEN; pyright net-zero on the
touched fixture file.

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
