# Demo Fixture Manifest

Demo fixtures are used for UI, API and QA/QC development before live data connectors are complete.

## Geel Building Detection Demo
Path: `demo/geel/`
Purpose: building detection and GRB-like reference QA.

Required fixture files:
- `area_geel_center.geojson`: analysis polygon.
- `reference_buildings.geojson`: GRB-like building reference layer.
- `demo_detections.geojson`: deterministic AI detection output.
- `expected_qaqc_metrics.json`: expected precision/recall/F1.

## Mol Vegetation Demo
Path: `demo/mol/`
Purpose: segmentation and vegetation/water area metrics.

Required fixture files:
- `area_mol_lakes.geojson`
- `demo_segmentation_vegetation.geojson`
- `expected_segmentation_metrics.json`

## Turnhout Change Demo
Path: `demo/turnhout/`
Purpose: vector change detection workflow.

Required fixture files:
- `area_turnhout_growth.geojson`
- `buildings_t0.geojson`
- `buildings_t1.geojson`
- `expected_change_metrics.json`

## Fixture Rules
- Fixtures must be small enough for git.
- Fixtures must not contain private data.
- Fixtures must be deterministic.
- Expected metrics must be versioned with the fixture.
