 ## Stage 7: Validate the final modules and workspace, then close the sprint
 
+**Complete.** Validation used Go 1.27.0 against source revision `e28ba63`
+with the final import-formatting and roadmap-closure changes in the completion
+commit. Dependency preparation (`go mod tidy`, `go mod download`, and
+`go list -m all`) used `GOWORK=off GOTOOLCHAIN=local`; the selected graph has
+the intended vanity modules and no local replacements or old-path PromptKit or
+ConfigKit imports. The root, ckconfig, and ckprompt modules each passed
+`GOWORK=off GOTOOLCHAIN=local go test -mod=readonly ./...` independently.
+
+The preserved ignored workspace was set to Go 1.27.0, keeping its three existing
+`use` entries. From the root, `GOTOOLCHAIN=local go test ./...`,
+`go test ./integrations/ckconfig/...`, and `go test ./integrations/ckprompt/...`
+all passed with workspace discovery. Changed Go files were formatted. Local
+Markdown destinations and fragments, source/notice pins, the complete sprint
+diff, and whitespace checks were reviewed. Deferred capabilities remain in
+[future work](future.md#promptkit-inspection-and-selection-extensions).
+
+All six standalone composed-consumer commands listed below returned status 0.
+The inspected source report included the application and bundled evidence;
+the selected spring profile and prompt, hash, and request validation appeared
+in their reports. Aggregate smoke selected the local backend, reported unavailable
+HTTP diagnostics, used the injected inference client, and recorded
+`valid_json: false` for structured output; its native facts did not alter the
+successful aggregate outcome. No publication or hosted delivery was performed.
