Symptom	Cause	Fix
Dataset not found or not GeoJSON	Slug missing from `datasets.json` or `format` is tabular	List GeoJSON datasets and re-prompt; suggest `portaljs-add-chart` for tabular data.
Source fetch/copy fails	URL returns non-200 or local path missing	Report the HTTP status or missing path; ask for a corrected source.
"Not valid GeoJSON"	Parsed JSON `type` isn't a Feature/geometry type	Tell the user and point to `portaljs-add-dataset` for tabular data.
`tsc` failure	Bad import path or gating condition	Fix the first reported error before reporting success.
Map appears on every dataset	View not gated on `(namespace, slug)`	Wrap the `<Map />` render in the dataset check shown in the Instructions.
Features render in the wrong place	Data isn't WGS84 (EPSG:4326) lon/lat	Reproject the source data to WGS84 before adding.
Slow render	Thousands of features in one file (>5MB)	Simplify geometries (e.g. `mapshaper`) before adding.
