+The docs service reads its source list once, when its container starts. Run
+`bin/context-kit restart` after changing `CONTEXT_KIT_DOCS_SOURCES` or editing

+A restart does not index a newly added source. Index it before anyone queries

+If `docs_sources` does not list a source you added, or `docs-rebuild` fails with
