+## Follow-up contribution review
+
+The complete seven-file contribution was reviewed again before the authorized
+merge and frontend rollout. No additional defects were found in the byte-copy
+boundary, provider reuse, cache disposal, error semantics/localization, privacy,
+architecture or regression coverage. No source changes were needed.
+
+Current `main` (`ec4115d`, including the birthday, signup-delivery and account
+setup changes) was merged into `kyc-69` before final verification. The two-file
+format check and app analyzer passed; all six Chrome preview regressions and
+all 240 tests in `make test-frontend` passed on the combined code. The original
+228-test result above describes the earlier isolated branch.
+
+The authorized rollout rebuilds only `frontend` from clean, pulled `main`, using
+the repository's fresh stable-release resolver and digest-pinned local inputs.
+Runtime image, HTTPS and served-bundle verification are recorded in task #69
+after the rollout; generated local pins remain ignored.
