Pre-slice `_is_off_peak_meter` carried its own string-dispatch that only recognised the RdSAP 10 long form `"off-peak 18 hour"`. The bare `"18 Hour"` lodging (Elmhurst Summary §14.2 surface form, lodged by 41/41 corpus variants) fell into the catch-all `return False` branch. That mis-classified every 18-hour cert as non-off-peak for the secondary / PV cost paths and billed electric secondary heating at standard 13.19 p/kWh (Table 32 code 30) instead of the 18-hour low rate 7.41 p/kWh (Table 32 code 40). The fix routes `_is_off_peak_meter` through `tariff_from_meter_type` so every lodging form already recognised there (int 1/4/5, `"18 Hour"`, `"off-peak 18 hour"`, `"Dual"`, `"Dual (24 hour)"`, numeric strings) is consistently classified. Single (code 2) stays standard; Unknown (code 3) retains the heuristic "electric end-uses on Unknown meters typically come from E7-eligible dwellings whose tariff the assessor couldn't pin down — apply off-peak". Per [[feedback-zero-error-strict]] the now-dead `_RDSAP_DEFINITELY_OFF_PEAK` frozenset is deleted (canonical dispatch covers the same codes). Spec citation per [[feedback-spec-citation-in-commits]]: > RdSAP 10 §17 page 85 row 10-2 (Electricity meter): "Dual / single / > 10-hour / 18-hour / 24-hour / unknown" > RdSAP 10 §12 page 62: "if the meter is dual 18-hour/24-hour it is > 18-hour/24-hour tariff" Corpus impact (6 storage-heater / underfloor variants on forced secondary): | variant | SAP code | old ΔSAP | new ΔSAP | |---|---:|---:|---:| | electric 3 | 401 | -0.10 | +2.42 | | electric 5 | 402 | -2.48 | -0.06 | | electric 6 | 404 | -1.14 | +1.19 | | electric 7 | 408 | -1.08 | +1.14 | | electric 8 | 409 | -2.54 | -0.41 | | electric 9 | 421 | -2.76 | -0.24 | Total absolute SAP residual across the cluster: 10.10 → 5.46. The 3 sign-flipped variants (electric 3/6/7) surface a separate cascade bug: `_secondary_heating_fraction_for_category` defaults to 0.10 when the mapper leaves `main_heating_category=None` for electric storage, but the worksheet for codes 401/402 uses 0.15 = Table 11 Cat 7. Mapper-side fix queued. Tests: - new AAA test `test_is_off_peak_meter_recognises_bare_18_hour_lodging` covers 7 lodging forms (bare, lowercase, long-form, Single, standard, Unknown+electric, Unknown+non-electric) - 6 corpus pins re-tightened (electric 3/5/6/7/8/9) Extended handover suite: 882 pass (was 881; +1 new test), 0 fail. Pyright net-zero on touched files (43 → 43 errors, all pre-existing). Per [[reference-unmapped-sap-code]] strict-dispatch routing. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> |

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
