   `3c0700b` revisions to their existing Gitea `origin/main` branches succeeded.
   A fresh fetch and ancestor check verified all four public references. No
   standalone code or dependency pin changed in this stage.
+- Stage 2: pipeline migration and existing integration cases passed `bash -n`,
+  the full role harness, and `git diff --check`; role commit `8ea8621`.
+- Stage 3: representative override, nullable omission, native effective views,
+  and clean repeats passed the full role harness; public assembly revision
+  `ea8b09e190419586ede6df3815d1ea999a0f4391`. A subsequent fixture-JSON

+- Stage 4: the exact public pipeline revision was subtree-imported. The
+  collection artifact harness passed with public dependencies, native base and
+  testing validation, and a clean repeat; public collection revision
