+2026-06-27: Added `tools/cmd/railiance-stage2` and dispatcher entries for
+`bin/railiance deploy` and `bin/railiance observe`. Deploy emits a
+`railiance.stage2-deploy-result.v1` plan by default, can run Helm server dry-run
+or apply when tools and cluster access are present, and fails closed when
+required paths, Helm, or approval evidence are missing. Observe emits a
+`railiance.stage2-observe-result.v1` target plan by default and runs live
+kubectl rollout, pod, ingress, and metrics checks only with `--live`. Updated
+generated overlays to declare the repeatable Stage 2 plan commands.
