Backend-Agnostic vs Honua-Server-Enhanced Capability Matrix

This is the generated, evidence-linked line between capabilities that work against raw standards-speaking endpoints and capabilities that require the Honua facade. The source of truth is config/support-manifest.v1.json. See the standalone quickstart for the runnable path.

Status vocabulary

supported — release-gated implementation with linked evidence
beta — implemented and evidenced, but still in pre-GA hardening
experimental — usable evidence-backed preview whose shape may change
deprecated — compatibility-only surface with a named replacement
unsupported — no implementation claim
facade-required — typed capability exists but execution requires Honua Server

Environment and execution mode are separate from status: standalone tells you where a claim works, while discovery, native, client-fallback, and facade tell you how it works.

Matrix

Capability	Status	Environment	Execution	Backend needed	API	Evidence	Notes
GeoServices FeatureServer query	`supported`	`standalone`	`native`	Any ArcGIS Server or ArcGIS Online endpoint	connect(), HonuaClient.queryFeatures, Source	fixture: connect-fixtures fixture: contract-conformance fixture: geoservices-conformance live: standalone-live	Discovers and uses the raw FeatureServer query path; fixture- and live-proven without a Honua account or server.
GeoServices MapServer reads	`supported`	`standalone`	`native`	Any ArcGIS Server or ArcGIS Online endpoint	connect(), HonuaClient.mapService, Source	fixture: connect-fixtures fixture: honua-surface-fixtures fixture: tile-layer-fixtures integration: map-service-integration live: standalone-live	Discovers and uses raw MapServer paths for layer queries, export, identify, legend, find, and cached tiles.
GeoServices ImageServer reads	`supported`	`standalone`	`native`	Any ArcGIS Server or ArcGIS Online endpoint	HonuaClient.imageService, Source.protocol()	fixture: geoservices-conformance integration: image-service-integration	Uses raw ImageServer paths for raster-catalog queries, export, identify, and cached tiles.
Esri compatibility layer	`supported`	`standalone`	`native`	Any ArcGIS Server or ArcGIS Online endpoint	@honua/sdk-js/esri-compat	fixture: esri-compat-fixtures	Compatibility classes parse public GeoServices URLs and create their own client.
ArcGIS scanner and migration codemod	`supported`	`build-time`	`static`	None	@honua/sdk-js/migration, honua-migrate	fixture: migration-fixtures	Static analysis and rewrites run locally; no service is involved.
Geometry operations	`supported`	`client-only`	`native`	None	@honua/sdk-js/geometry	fixture: geometry-fixtures	Buffer, area, simplify, measure, and reprojection run in the client through optional peers.
OGC API Features	`supported`	`standalone`	`discovery`	Any OGC API Features server	connect(), Source with locator.layout=ogc-api or auto	fixture: ogc-features-fixtures live: standalone-live	Discovers collections and item links from a raw landing page; the Honua facade remains a zero-round-trip fast path.
WFS 2.0	`supported`	`standalone`	`discovery`	Any WFS 2.0 server	connect(), Source, HonuaWfs	fixture: wfs-fixtures live: standalone-live	Uses the DCP operation URLs advertised by GetCapabilities instead of assuming a server path.
STAC API and static catalogs	`supported`	`standalone`	`discovery`	Any STAC API or static catalog	connect(), Source with locator.layout=stac-api or stac-static	fixture: stac-fixtures live: standalone-live	Searches a raw STAC API or walks static catalog links with client-side filtering.
OData v4	`supported`	`standalone`	`discovery`	Any OData v4 service	connect(), Source, HonuaOdataEntitySet	fixture: odata-fixtures live: standalone-live	Reads $metadata, intersects advertised capabilities, and uses the raw service root.
GeoParquet asset discovery	`experimental`	`client-only`	`discovery`	None; caller provides a GeoParquet profiler	connect({ protocol: 'geoparquet', geoparquet: { profiler } })	fixture: geoparquet-connect-fixtures	Profiles one or more assets and returns reviewed Source descriptors; query execution remains injected through the optional GeoParquet resolver.
OGC API Tiles	`beta`	`standalone`	`discovery`	Any link-driven OGC API Tiles server	connect(), Source protocol ogc-tiles	fixture: ogc-tiles-fixtures	Discovers raw landing, conformance, collection, tileset, and tile links; does not rewrite them to /ogc/tiles.
OGC API Maps	`beta`	`standalone`	`discovery`	Any link-driven OGC API Maps server	connect(), Source protocol ogc-maps	fixture: ogc-maps-fixtures	Discovers and renders from the raw map path advertised by the service; does not require /ogc/maps.
OGC API Records	`beta`	`standalone`	`discovery`	Any link-driven OGC API Records server	connect(), Source protocol ogc-records	fixture: ogc-records-fixtures	Discovers and queries the raw records path advertised by the service; does not require /ogc/records.
OGC API Processes discovery	`experimental`	`standalone`	`discovery`	Any link-driven OGC API Processes server	discoverOgcProcesses()	fixture: ogc-processes-fixtures	Discovers conformance and process metadata at raw paths. Processes are not a protocol-neutral Source.
OGC API Processes execution	`facade-required`	`honua-facade`	`facade`	Honua Server	HonuaClient OGC Processes methods	integration: ogc-processes-integration	Typed execution uses the Honua facade today; raw third-party execution is not claimed.
Server compatibility gate	`facade-required`	`honua-facade`	`facade`	Honua Server	HonuaClient.checkCompatibility()	fixture: server-compatibility-fixtures	Reads the Honua administrative capabilities contract and should be skipped for standalone reads.
Authored MapPackage runtime	`facade-required`	`honua-facade`	`facade`	Honua Server	@honua/sdk-js/runtime	fixture: map-package-fixtures	Loads server-authored styles, layer order, and metadata.
Realtime subscriptions	`facade-required`	`honua-facade`	`transport`	Honua Server	@honua/sdk-js/realtime	integration: realtime-integration	Subscription-backed live updates depend on the Honua realtime contract.
Collaboration and saved maps compatibility shim	`deprecated`	`honua-facade`	`facade`	Honua Server and @honua/app-platform	@honua/sdk-js/collaboration	Lifecycle-only claim	The SDK entrypoint is a temporary shim; new code imports @honua/app-platform/collaboration.
MCP tools and AI execution	`facade-required`	`honua-facade`	`facade`	Honua Server and @honua/mcp-server	mcp/, @honua/sdk-js/agent-tools	fixture: agent-tools-fixtures	Tool definitions are local, while discovery and query execution use the bounded Honua server surface.

Current OGC line

Raw OGC API Tiles, Maps, and Records discovery/use is beta and fixture-proven. Raw OGC API Processes discovery is experimental; typed Processes execution is still facade-required. Those are deliberately separate claims so discovery evidence can never be mistaken for execution support.
