+- Native desktop build and guarded opening tests passed on Windows.
+- Genuine multilingual CPU model proof: 5/6 top-1, 6/6 recall@3; quality gate remains open.
+- Native Rust CPU embedding adapter verifies pinned model/tokenizer assets;
+  integration with the search index and platform runtime packaging remain open.
+- PDF page and DOCX paragraph matches persist; corrupt/encrypted/over-limit
+  documents remain filename-searchable and report extraction errors.
+- CLI exposes folder/type/size/date filters and additional directory exclusions.
 
 The partial features above do not close broader production milestones such as
 crash-resumable jobs, fuzzy retrieval, watcher reliability or performance targets.
