GpkgController exports the tables and views under a catalog path (default: the %catalog use(...) context) to one .gpkg file, written with sqlite3, shapely and pyproj (no GDAL): - Spatial or tabular is decided per table from the data: a column holding WKB/EWKB, WKT/EWKT, hex WKB or GeoJSON, else latitude/longitude columns. Spatial tables become feature layers, the rest attribute tables. - Each row's CRS comes from the geometry (EWKB/EWKT SRID), else a CRS column (srid, sr_id, epsg, crs, ...), else EPSG:4326 for latitude/longitude. - Options: tables, limit per table, srid to reproject to, filename, output_dir (default <dataset>.gpkg next to the notebook), overwrite, workers. - CRS definitions for reprojection and gpkg_spatial_ref_sys come from geopackage/epsg_definitions.json, falling back to pyproj's EPSG database. Streaming: workers tables are read at once, each over its own Arrow Flight gRPC channel, a batch at a time; workers decode, reproject and encode, and one thread owns the SQLite file, fed through a bounded queue. The file is built under a temporary name with no journal, in one transaction, and renamed into place only when every table succeeded. FlightSqlExecutor gains stream_batches (no overall deadline on reading, parallel endpoints, cancel on early stop), fork() and thread-safe login; Catalog gains stream_rows and open_flight_channel. Also ignores *:Zone.Identifier download metadata. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Redmine-Hook: v1
- export prints a line as each table/view is written (layer, source, kind, geometry type, SRS, rows, seconds, notes) or fails (naming the table and the error; the export then stops and no file is written), plus a start line and a total. GpkgController takes a progress callback (default: log only); the %gpkg session passes print. Each layer records its seconds. - GpkgReport is os.PathLike (the written file), so `report = %gpkg export()` then `%dds push(DELIVERABLES, report)` uploads the .gpkg. .gpkg is registered as application/geopackage+sqlite3. - %gpkg / %dds help and the README show both.

Brings development up to date with staging (ingest PY-7 to PY-13, %ingest diagnose / options / cleanup_on_failure, foldertree copy and move, non-UTF-8 CSV check, the main ingest fix). catalog/client.py conflicted only because both sides added to Catalog: kept both — stream_rows / open_flight_channel (development) and getentriesfrom / entryexists / getviewsql / createviewas / getfoldersfrom and the foldertree imports (staging).

Merge staging into development
test_a_gpkg_export_can_be_pushed_with_dds imported FakeSource from tests.geopackage.conftest. That works under `python -m pytest` (the repo root is on sys.path) but not under plain `pytest` as CI runs it, where `tests` is not importable. The test now defines its own one-table source.

debugger/test_catalog_magic.ipynb gains cells for %gpkg help, exporting a dataset (limit=100) and pushing the result with %dds push(DELIVERABLES, ...). The output.gpkg those cells write is git-ignored. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Redmine-Hook: v1

%gpkgmagic andgeopackagepackage. It exports the tables and views under a Dremio catalog path (by default the%catalog usecontext) to a GeoPackage 1.4 file, written with pure-Python libraries (sqlite3, shapely, pyproj).tables,limit,srid(reprojection, using definitions fromepsg_definitions.json),filename,output_dir,overwrite,workers.report = %gpkg export()followed by%dds push(DELIVERABLES, report)works.Merged into staging through #100.
