+Policies to validate build sources and metadata. Each entry uses the same keys
+as the `--policy` flag for `docker buildx build` (`filename`, `reset`,
+`disabled`, `strict`, `log-level`). Bake also automatically loads
+`Dockerfile.rego` alongside the target Dockerfile when present.
+
+```hcl
+target "default" {
+  policy = [
+    { filename = "extra.rego" },
+  ]
+}
+```

 ### `target.platforms`

 Set target platforms for the build target.
