Elmhurst Summary §14.0 Main Heating1 normally closes at "14.1 Main
Heating2", but community-heated dwellings and "no system" certs lodge
§14.0 followed directly by "14.1 Community Heating/Heat Network" (no
second main system exists on a community-heated dwelling). Pre-slice
the extractor's `_between("14.0 Main Heating1", "14.1 Main Heating2")`
returned an empty string for these shapes — every §14.0 field
(including `Main Heating SAP Code`) came back None, then the mapper
strict-raised `UnmappedElmhurstLabel` with "§14.0 Main Heating1 has
neither PCDF boiler reference (None) nor SAP code (None)".
The fix adds a `_section_lines_first_end(start, ends)` helper that
accepts a tuple of end-marker candidates and uses whichever appears
first after `start`. `_extract_main_heating` now closes §14.0 at
either "14.1 Main Heating2" or "14.1 Community Heating" — whichever
Summary lodges.
Impact on heating-systems corpus 001431 at `sap worksheets/heating
systems examples/`:
Variant Pre-S0380.128 -> Post-S0380.128
------------------------ ------------------ -----------------
community heating 1 mapper-raise -> SAP code 301 OK
community heating 2 mapper-raise -> SAP code 302 OK
community heating 3 mapper-raise -> SAP code 304 OK
community heating 4 mapper-raise -> SAP code 302 OK
community heating 6 mapper-raise -> SAP code 302 OK
no system mapper-raise -> SAP code 699 OK
Corpus tally: **35/41 -> 41/41 cascade-OK**. With all populated
variants now executing, the cascade-vs-worksheet residual cluster is
fully visible for the first time. Notably community heating 6 surfaces
the FIRST negative ΔSAP in the corpus (-6.87 — cascade undershooting
the worksheet rather than overshooting), a distinct diagnostic shape
worth investigating next.
The fix is structural (extractor section bracketing) — no spec rule
to cite. RdSAP 10 §17 page 85 row 1.0 ("Main Heating") + §17 row
10-1a ("Community Heat Source") confirm that community-heated certs
have only one main heating system (no Main 2 block).
Extended handover suite at HEAD post-slice: **832 pass, 0 fail**
(was 831 + 1 new AAA test).
Pyright net-zero on touched files (13 → 13 — pre-existing errors
unrelated).

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
