+**Completed:** All workspace suites passed on Go 1.26.8: root, ckconfig, and
+ckprompt, including maintained examples. Independent `GOWORK=off` checks also
+passed for all three modules using the root module graph and disposable local
+source replacements; only replacement directives changed in temporary module
+files, with no sum changes. The final review confirmed core has no optional
+integration dependency, backend imports remain internal, integration factories
+return canonical commands, and alias composition is covered without provider
+loads during help. Routing, flag interpretation, help, diagnostics, identity,
+installation recovery, typed bindings, and consumer composition are covered by
+the focused evidence recorded in Stages 1–14. Documentation links and
+candidate-note paths resolve; prose whitespace checks passed. The alias feature
+roadmap now records completed implementation while leaving core publication
+and dependent integration release preparation separate.
