 - Proceed to Stage 2 (transfer package refresh and integrity check).
 
+### Stage 2 - Completed
+
+Scope:
+
+- Refresh transfer artifacts from baseline `8ba0561f..c27bf084`.
+- Verify bundle metadata.
+- Verify patch chain applies cleanly on a detached baseline worktree.
+
+Artifacts:
+
+- `artifacts/git-patches/full-stabilization-current/` (12 patches)
+- `artifacts/git-patches/vpnruntime-ci-stabilization-current.bundle`
+
+Verification:
+
+- `git bundle verify artifacts/git-patches/vpnruntime-ci-stabilization-current.bundle`: PASS
+- `git am --3way <12 patches>` on detached worktree from `8ba0561f`: PASS
+
+Notes:
+
+- Local git version does not support `git am --dry-run`; compatibility check was
+  performed via real `git am --3way` in throwaway worktree and then worktree
+  removal.
+
+Next:
+
+- Proceed to Stage 3 (remote push handoff readiness; auth-dependent).
