 When provider configuration or code changes, rebuild the provider binary first, then re-run `terraform validate` and `terraform plan`.
 
+### Version metadata in binaries
+
+The provider embeds build metadata (`version`, `commit`, `date`) in the binary.
+
+- Local builds (no `-ldflags`) default to:
+  - `version=dev`
+  - `commit=none`
+  - `built=unknown`
+- You can inspect metadata from the binary with either:
+  - `./terraform-provider-dynu --version`
+  - `./terraform-provider-dynu version`

+Build a stamped binary with standard Go `-ldflags`:
+
+```bash
+VERSION=${VERSION:-v0.2.0}
+COMMIT=$(git rev-parse --short HEAD)
+DATE=$(date -u +%Y-%m-%dT%H:%M:%SZ)
