Khalim Conn-Kowlessar 395ad30c48 Slice S0380.13: widen cantilever gate to accept "House" descriptive form
Closes cert 2636 to spec floor (Δ +0.5167 → +0.0323) by accepting
both the EPC schema enum-as-string ("0") AND the Elmhurst Summary
mapper's descriptive form ("House") for the cantilever-detection
property-type gate at `heat_transmission.py:768`.

Root cause: slice 102f-prep.9 (commit 06b4ef3d) added cantilever
detection gated on `epc.property_type == _PROPERTY_TYPE_HOUSE` where
`_PROPERTY_TYPE_HOUSE = "0"`. That matches the API mapper's encoding
(schema enum), but the Summary mapper produces "House" (descriptive)
and the hand-built worksheet fixtures also use "House" — so neither
triggers the gate and the cantilever path silently no-ops on the
Summary path. Cert 2636's worksheet (28b) "Exposed floor Main 3.74
× 1.20 = 4.4880" is the cantilever — without surfacing it the
cascade missed 4.488 W/K of floor heat loss.

Three-encoding origins:
- API mapper:        property_type='0'      (schema enum-as-string)
- Summary mapper:    property_type='House'  (descriptive from §1)
- Hand-built fixtures: property_type='House' (legacy convention)

Fix: replace the equality check with a `_is_house()` helper that
accepts the {"0", "House"} frozenset. Centralised so future
property-type sensitive gates can call the same helper.

Forcing function: cert 2636 first-attempt Summary SAP closes from
Δ +0.5167 (after S0380.12 walls fix) to Δ **+0.0323** — within the
±0.07 ASHP-cohort spec floor. `floor_w_per_k` moves from 19.1982
(ground floor only) to 23.6862 (ground 19.20 + cantilever 4.49 =
worksheet (28a) + (28b) exact match).

  9418  +2.5973         ✗  (Daikin EDLQ05CAV3 — final cert)

Boiler hand-built parity verified intact: 5 hand-built cohort certs
(000474, 000477, 000480, 000490, 000516) all use property_type=
"House" and now also fire the cantilever gate, but none have
floor1_area > floor0_area + 1m² (the cantilever-area trigger) so
their cascade output is unchanged. Regression suite 683 pass + 10
fail (= handover baseline 669 + 10 + 17 new GREEN tests across
S0380.2..S0380.13).

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
