+2026-07-26: Added `docs/retained-s1-handoff.md` to define the migration-window

+the grouped home-reef identity, topology, hosted-rail stance, and future
+`rapp` bindings, while `railiance-infra` retains raw inventory, provisioning,
+and broader S1 source-backed host facts. `README.md`, `docs/README.md`,
+`docs/wave-1-contract.md`, `docs/source-import-plan.md`, and `SCOPE.md` now
+point operators at the explicit no-flag-day handoff.
