+- [ ] Wait until upstream branches and their landing order are
+  settled; preserve a reference to the draft snapshot.
+- [ ] Reset/unpack draft commit e815fd77 while retaining the full TC
+  changeset and preserving unrelated working-tree and staged work.
+- [ ] Prepare a proper commit plan for that changeset with coherent
+  behavior boundaries, matching tests, docs and provenance.
+- [ ] Run each boundary's checks and review its diff and message
+  before recommitting.
