Foggy Capability Baseline and Evidence Matrix ​

This page is the current capability source for the implementation manual. It is not frozen v3.0 whitepaper content. The evidence was collected on 2026-08-22 against a disposable SQLite fixture and the Java Runtime. Production deployments must repeat the checks and add authentication, authorization, audit, network, and secret controls.

none-dev-test-only is a development/test boundary, not a production security conclusion. Every deployment should read /api/v1/capabilities first and select the next steps from the reported capabilities.

Capability matrix ​

Status meanings: Verified means the disposable fixture executed successfully; Declared/not exercised means the Runtime advertises the capability but this run did not consume it; Conditional depends on configuration, identity, or an optional service; Disabled is explicitly unavailable in this instance.

CapabilityCurrent statusRuntime/API or MCP entry pointEvidence and documentation decision
Readiness and capability discoveryVerifiedGET /readyz, GET /api/v1/capabilitiesReturned Java, API v1, and schema 2026-06-06; every implementation flow starts here.
Runtime security modeConditionalsecurityMode, management-auth configurationCurrent mode is none-dev-test-only; the manual must not present the local Launcher as production-ready.
Datasource list/testVerifiedGET /api/v1/datasources, POST /api/v1/datasources/{name}/testThe default datasource passed its test; diagnostics must not expose passwords or complete connection strings.
Namespace datasource bindingVerifiedPUT /api/v1/namespaces/{namespace}/datasourceModel validation failed in a fresh unbound namespace; binding default enabled the successful flow. Binding is a model-validation prerequisite.
Datasource diagnosticsVerifiedGET /api/v1/datasources/diagnosticsReported namespaceBindings.salesdrop=default; managedDatasourceCount=0 does not mean that a configured datasource is unavailable.
Table list and inspectionVerifiedPOST /api/v1/tables/list, POST /api/v1/tables/inspectsales_drop_daily was inspected; this is controlled operations/modeling access, not a substitute for semantic queries.
Runtime SQLVerified but restrictedPOST /api/v1/sql/queryA read-only top-five query passed; the SQL surface must not become a normal MCP user-query endpoint.
Bundle registrationVerifiedGET/POST /api/v1/bundlessales-drop-models was registered before refresh; registration alone does not publish a model.
Model validationVerifiedPOST /api/v1/models/validatePassed after datasource binding; validation produces candidate diagnostics and does not replace the catalog directly.
Model refresh/list/describeVerified/api/v1/models/refresh, GET /api/v1/models, POST /api/v1/models/{model}/describeRefresh exposed SalesDropDailyQueryModel; describe returned 21 fields and physical-table mapping.
Query validate/executeVerified`/api/v1/query/{model}/validateexecute`
Query explainVerified/api/v1/query/{model}/explain, dataset.explain_querybasis=RECOMPILED; this is fresh compilation evidence in the current context, not a historical execution trace.
Compose/FSScriptDeclared/not exercised`/api/v1/compose/validatepreview
Authoring workspace/resources/diff/validateDeclared/not exercised/api/v1/authoring/...The capability is supported; publish, recovery, and concurrent-revision behavior need a separate management-plane acceptance run.
Release package exportDeclared/not exercised/api/v1/authoring/workspaces/{id}/release-packageAdvertised as supported; this run does not claim that a release drill is complete.
Production apply/rollbackDisabledauthoring.production.apply/rollback capabilitiesExplicitly disabled in this instance; the v3.0 draft must preserve this conditional/disabled wording.
Release package importDisabledauthoring.releasePackage.import capabilityExplicitly disabled; the deployment manual must not promise direct production import.
MCP model discoveryVerifieddataset.list_modelsPreferred discovery tool; it returns routing information, followed by dataset.describe_model_internal.
MCP model detailsVerifieddataset.describe_model_internalTakes model; new integrations must not use dataset.get_metadata for first-pass discovery.
Legacy metadata toolCompatibility/deprecateddataset.get_metadatatools/list marks it Deprecated; new integrations must migrate to list + describe.
Single-model queryDeclared with API evidencedataset.query_modelSingle-model filters, grouping, time windows, and pivot route here; cross-model work must not be forced into it.
Cross-model compositionDeclared/not exerciseddataset.compose_scriptUse only for Join/Union/derived/multi-plan flows; scripts must return { plans: plan }.
Chart exportConditionaldataset.export_with_xchart, dataset.export_with_echartsXChart is JVM-native with no browser/Node dependency; ECharts requires an optional rendering service and an explicit choice.
Natural-language queryConditionaldataset_nl.queryRequires a ChatModel/AI Provider; structured tools should not be described as unavailable when the provider is absent.

Items for the v3.0 review ​

  • Keep DRAFT / NOT FROZEN until the product and architecture owners confirm this matrix and the compatibility policy.
  • Make datasource binding, model validate/refresh, catalog generation, and tool migration explicit implementation prerequisites.
  • Define RECOMPILED separately from historical execution traces, and state that SQL/physical-name exposure is governed by namespace policy.
  • Put the disabled/conditional state of production apply, rollback, and import in the compatibility matrix instead of promising a complete release loop early.

Reproduction entry point ​

See Runtime API and MCP Examples for curl, MCP JSON-RPC, and CLI examples. Delivery evidence should retain the JSON responses for capabilities, datasource diagnostics, model validate/refresh, and query validate/execute.
