# Acceptance Test Catalog

## Foundation
- Health endpoint returns application status.
- API error responses follow the standard envelope.
- CORS is configured for frontend local development.
- Database connection failure is reported but does not crash import-time tests.

## Projects
- Create project with valid payload.
- Reject empty name.
- List projects sorted by newest first.
- Get missing project returns 404 envelope.

## Areas
- Create area from valid Polygon GeoJSON.
- Reject invalid geometry.
- Store geometry with expected SRID.
- Return FeatureCollection for project areas.

## Datasets
- Upload supported vector file.
- Extract geometry type, feature count, bounds and CRS when available.
- Reject unsupported extension with explicit error code.
- Dataset status transitions: uploaded -> metadata_extracted -> ready or failed.

## Raster
- Read raster metadata when valid raster available.
- Return band count, bounds, CRS, width, height and resolution.
- Clip request creates a processing job.
- Tile request creates deterministic tile manifest.

## Vector
- Read vector metadata from GeoJSON fixture.
- Clip vector features to area.
- Buffer vector features by distance in meters.
- Intersect two vector layers.

## Detection
- Create detection analysis run.
- Demo-mode detector creates stable predictions.
- Detections include class, confidence, geometry and source tile.
- Detection outputs are exportable as GeoJSON.

## Segmentation
- Create segmentation analysis run.
- Demo-mode segmenter creates stable polygons.
- Segmentations include class, area_m2, confidence and optional mask path.

## QA/QC
- Match detection to reference by IoU threshold.
- Calculate TP, FP, FN.
- Calculate precision, recall and F1.
- Generate false positive and false negative layers.

## Frontend
- Every route has loading, empty, error and success states.
- Project creation navigates to workspace.
- Map page can render GeoJSON area fixture.
- Dataset detail shows extracted metadata.
- Analysis status updates are visible.

## Export
- GeoJSON export returns downloadable file.
- CSV metrics export includes metric key, value and unit.
- Export records are listed in project exports.
