 # Roadmap: migrate to the ReleaseKit vanity module path
 
-Status: implementation in place; final verification and completion review underway.
+Status: implementation complete; offline verification and completion review passed.
 
 ## Objective
 
@@ -158,3 +158,50 @@ Publication follows the existing [release procedure](../release.md). Reuse
 successful validation where it applies to the exact candidate, as allowed by
 the release policy. Track source publication and hosted-page delivery
 separately under that procedure.
+
+## Completion review
+
+Implementation is committed in `3b803d5`. Verification used Go 1.26.10 on
+linux/amd64 with local toolchain selection. The following work is complete:
+
+| Work | Completion evidence |
+| --- | --- |
+| Source and embedded identities | Module declaration, imports, version-injection symbol, and API checker use the vanity path; compiled API/dependency checks passed. |
+| Fixtures and examples | Generated consumer modules, synthetic proxies, launchers, and workflows use the vanity identity; the full offline suite passed, including executable-workflow and tagged-retry coverage. |
+| Adoption and release guidance | Current guides and examples describe the new paths; `docs/releases/v0.5.0.md` records compatibility impact, migration steps, and the immutable-tag licensing footer. |
+| Gitea hosting references | Delivery profile, runbook, current source links, and fixture expectations use `forge.maximumdirect.net/base-layer/releasekit`; a one-time repository API read returned that repository identity. |
+
+The complete offline suite passed against the committed implementation:
+
+```sh
+GOTOOLCHAIN=local GOWORK=off GOPROXY=off GOSUMDB=off \
+  go test -mod=readonly -count=1 ./...
+```
+
+The compiled facade/dependency checks and dependency-metadata review passed:
+
+```sh
+GOTOOLCHAIN=local GOWORK=off GOPROXY=off GOSUMDB=off \
+  go run ./internal/apicheck
+GOTOOLCHAIN=local GOWORK=off GOPROXY=off GOSUMDB=off \
+  go mod tidy -diff
+```
+
+Build/version-injection integration tests passed. An additional disposable
+consumer removed the original CLI tool declaration, registered the vanity-path
+CLI through a local source replacement, and ran `go tool releasekit version`
+successfully. Its executable imported the root facade and `buildinfo` and
+reported the injected `v9.8.7` version. These were offline checks using temporary
+consumer metadata.
+
+The completion review found no original-path references in Go source. Current
+documentation retains the old path only to explain migration and older
+releases. A source comparison confirmed that Go changes consist of module-path
+substitutions and the separately reviewed hosting-fixture updates. Existing
+release records, ADRs, upstream attribution and policy provenance, dependency
+checksums, and the Go 1.26.0 minimum are preserved. Documentation links, heading
+fragments, example shell syntax, formatting, and whitespace checks passed.
+
+The implementation is ready for release preparation. Source publication and
+fresh consumption of a published vanity-path version remain release follow-up
+under the procedure above.
