# Milestone 4 & 5 Verification: TEST_READY
This document verifies the completion of Milestones 4 and 5 for the LSP 3.18.0 Upgrade in `lsp-types`.
## Verification Status
| **Compilation** | 0 Errors | 0 Errors | ✅ PASS |
| **Test Suite execution** | 100% Pass Rate | 100% Pass Rate | ✅ PASS |
| **Total Test Count** | >= 126 tests | 126 tests | ✅ PASS |
## Supported Feature Sets
All 11 required LSP 3.18.0 feature sets have been implemented and verified via comprehensive Tier 1-4 tests (opaque-box, boundary, adversarial, semantic, fuzz, pairwise, and scenarios) alongside robust layer 5 fuzzing.
The implementation modules are securely isolated as `agent1_inline` through `agent10_misc_ext` directly within `src/` to prevent concurrency race conditions, demonstrating the successful orchestration of independent agents over specific feature boundaries.
The following targets are complete:
1. `textDocument/inlineCompletion`
2. `workspace/textDocumentContent` & `workspace/textDocumentContent/refresh`
3. `textDocument/rangesFormatting`
4. `workspace/foldingRange/refresh`
5. Notebook Document Synchronization
6. Cell Diagnostic Pull
7. Proposed `CodeActionKind.RefactorMove` and `CodeActionTag.LLMGenerated`
8. `SnippetTextEdit` and `WorkspaceEditMetadata`
9. `CompletionList.itemDefaults`
10. `MessageType.Debug`
11. Relative Glob Patterns
All implementations correctly handle Serde round-tripping for canonical JSON structures defined by the language server protocol boundary.
## Next Steps
The repository is now fully prepared for Release. All automated tests within `cargo test --test e2e_spec_3_18` execute successfully.
