-**Completion evidence:** all three default suites, independent module graph
-reviews (with local-source limits identified when applicable), maintained consumer
-results, feature-to-evidence audit, and reviewed final documentation/distribution
-changes. No significant product/API decisions remain open in this plan.
+**Completion evidence — complete:** the workspace `go test ./...` commands pass
+at the root and in both integration modules. Core also passes
+`GOWORK=off GOTOOLCHAIN=local go test -mod=readonly ./...`; its workspace-off
+module and package graphs retain ReleaseKit v0.4.0 and exclude ConfigKit,
+PromptKit, and the integration packages. Both integrations pass their
+workspace-off tests and read-only module/package graph checks with disposable
+modfiles containing only the planned local replacements for unpublished
+CommandKit modules. Those graphs select ConfigKit v0.7.1 and ReleaseKit v0.4.1;
+ckprompt retains PromptKit v0.12.0. Direct package imports stay within the
+integration boundaries. The alternate-file checks establish compatibility with
+the local CommandKit sources and released external dependencies, not availability
+of the future CommandKit module tags.
+
+The maintained simple and composed diff commands emit their expected YAML
+changes (`greeting: Goodbye` and `default_campaign: autumn`) with no stderr.
+Default show/greet, composed validation, named prompt inspection, and session
+restore commands also succeed. Code graph and focused test review covers paired
+input timing, callback-free discovery, equal-selection loads, diagnostic
+retention, native safe values and concealed changes, all report categories,
+null/deletion distinctions, delivery failures, fresh invocation state, and
+ordinary inspection regressions. `ConfigScope` still declares only validate,
+show, sources, and explain. Stage 12's notice, release-note, metadata, link, and
+whitespace evidence is recorded above. No release was published or release
+launcher run, and no significant product/API decisions remain open.
