+This updates `vestige`, `vestige-mcp`, `vestige-restore`, and the Cognitive
+Sandwich companion files. The companion refresh keeps hooks disabled by default
+and cleans up old mandatory v2.1.0 hook wiring.

+**Binaries only:**
+```bash
+vestige update --no-sandwich

 **Pin to specific version:**
 ```bash
 vestige update --version v2.1.1
