+
+## Raster rules
+
+- Preserve georeferencing metadata.
+- Never drop CRS silently.
+- Keep raster-derived outputs traceable to source dataset and parameters.
+- Use deterministic tile naming.
+- Store heavy outputs under documented storage roots, not random folders.
+- For V1, prefer metadata and small fixtures over heavy real rasters.
+
+## Operations checklist
+
+- [ ] Validate raster readable.
+- [ ] Extract CRS, bounds, transform, dimensions, band count, dtype.
+- [ ] Clip by area where requested.
+- [ ] Generate tiles with configured tile size and overlap.
+- [ ] Preserve mapping from tile pixels to map coordinates.
+- [ ] Emit metadata JSON for downstream services.
+- [ ] Add tests with tiny raster fixtures when possible.

+## Completion report fields
