+- Session durability checkpoints use the operator's git `user.name` and
+  `user.email` when both are set, so allowlisted commit-author hooks no
+  longer fail every tool cycle. Machines without a git user still fall
+  back to the Interchange harness identity.
+- First-run welcome plays the mountain once and holds the filled
+  silhouette until continue or auto-advance. The product line is hidden
+  on narrow terminals instead of wrapping mid-word.
