GeneGIS v0.9.0 — Phase 9 External Data

Summary

Phase 9 completes external STAC discovery, GeoParquet workflows, and release hardening for the agent orchestration layer.

Highlights

Phase 9 alpha

• External STAC fetch/import with catalog overlay
• CLI genegis catalog stac fetch|import
• Workflow nagoya-geoparquet with offline feature-count verification

Phase 9 beta

• Planner stac_fetch tool for external collection URLs
• Workbench STAC import panel (/api/stac/fetch|import|overlay)
• GeoParquet density pipeline (nagoya-geoparquet-density + DuckDB verify)
• Workflow external-stac-demo

Phase 9 gamma

• CI six-workflow agent matrix (north star + 5 Phase 9 workflows)
• Audit bundle v3 — alpha + overlay + merged STAC snapshots
• Ask pipeline smoke for GeoParquet density
• Overlay path isolation (GENEGIS_CATALOG_OVERLAY_PATH) for tests
