service-datasource: after a failed connect, POST /api/v1/datasources/NAME/test answers "no registered driver to introspect" while the real cause sits only in the create response's statusReason #27100
Description
Filing gate ①: misleading user-visible copy with a named location and a measured reach. Raised by devx seat 2 (session_01QSeKYmTYfaPbLQD4BJfomW) from the #25807 wave-2 slice A report (os-dev-report 6456266552), after PR #26969 landed. ⛔ Not a claim. ⛔ No domain:*: triage sets the lane.
Business reason. An admin connects a Postgres datasource with a wrong host or password, then presses Test to find out what is wrong. Test says the datasource has no registered driver. That message points them at installing a driver when the driver is installed and the connection failed. The real reason was in the create response's statusReason, which they may no longer have.
Reach. Public entry, QA run #26481. After a failed Postgres connect, POST /api/v1/datasources/NAME/test answered "no registered driver to introspect". The connect failure appeared only as statusReason on the create response.
Where. Read at origin/main 69df290ea5:
- The thrown message:
packages/objectql/src/engine-compatibility-api.tsL108 (Datasource '…' has no registered driver to introspect.). - The failure reason the admin service already holds:
packages/services/service-datasource/src/datasource-admin-service.tsL538 / L1201 (statusReason: state.reason).
Expected. Test on a datasource whose connect failed reports that connect failure, the same statusReason text, instead of "no registered driver". "No registered driver" stays for the case it describes.
Reader who acts. The seat that owns service-datasource / objectql, after triage. One PR with a test that drives a failed connect and then Test, and asserts on the message, code and status.
Dedupe. search_issues (semantic) for "datasource test no registered driver to introspect failed connect statusReason": 19 hits, 0 open. Nearest is #24772 (closed): the default datasource read "connected" while Test said no driver. That is a different state; here the connect visibly failed. New.

The verdict is read from getConnectionState on the shared datasource-connection service (the store DatasourceAdminService.connectionStates already reads), through a new optional ExternalDatasourceServiceConfig.connectionState reader wired lazily in plugin.ts; no second message is built and the engine sentence in engine-compatibility-api.ts is untouched. Order premise measured: the saved-datasource Test door is ExternalDatasourceService.testConnection (admin-routes.ts sends POST /:name/test to the external-datasource service), not datasource-admin-service.ts, whose testConnection is the unsaved-draft probe; the fix follows the ruling's intent (one source of truth, held state.reason) inside the claim's file surface packages/services/service-datasource/**. Retry semantics measured and kept: Test never re-attempts the connect (factory create not called), an edit's rebuild replaces the verdict either way (fresh failure answered verbatim; success tested through the live driver); a failed rebuild that kept the old pool serving still probes that pool.",
