+# Registry Stack language server
+
+`registry-language-server` adds Registry Stack project semantics to YAML editors through the
+Language Server Protocol. It discovers the bounded authoring surface rooted at
+`registry-stack.yaml` and indexes:
+
+- registry, integration, entity, service, consultation, claim, credential-profile, fixture, and
+  environment definitions;
+- integration and entity aliases across the project manifest, their definition files, and
+  environment files;
+- consultation integration references, records-service entity references, credential-profile
+  claim references, direct claim-output consultation references, and fixture expected-claim
+  references.
+
+It provides go to definition, find references, workspace symbols, document symbols, and errors for
+missing, duplicate, or ambiguous references. It deliberately leaves syntax, schemas, completion,
+hover, and formatting to the editor's YAML language server.
+
+## Run
+
+```console
+cargo run -p registry-language-server
+```
+
+The same server is available from a release installation as:
+
+```console
+registryctl authoring language-server
+```
+
+The server communicates over standard input and output and expects the opened workspace (or a
+nested directory) to be inside a Registry Stack project.
+
+Only regular files in the documented Registry Stack project layout are indexed. Symbolic links,
+files outside the project root, unrelated YAML files, and project documents larger than 1 MiB are
+ignored. This keeps editor analysis inside the same bounded authoring surface as `registryctl`.
