Analysis, geometry, and topology

Generated from the same registry as the Chinese reference. Contract version: 0.5-session. Edit the registry and reviewed English catalog, then rerun script_contract; do not edit this file. See the script guide.

Platform labels below are registry declarations, not device acceptance. Consult the platform coverage guide for actual host coverage and limits. These are the existing gis compatibility-module APIs; the shared sqsmap map facade is documented separately.
