+
+Implemented in this pass:
+
+- Browser Binding action aliases and path-addressed routes:
+  `cmisaction=update`, `cmisaction=move`, and `/browser/root/{path}`.
+- MIME normalization and explicit content stream `Content-Type` headers.
+- Metadata-backed standard property support for `cmis:name`,
+  `cmis:description`, and `cmis:secondaryObjectTypeIds`.
+- Create-time secondary type id projection and invalid document type rejection.
+- Removal of non-standard document `cmis:path` while preserving folder paths.
+
+Latest verification:
+
+- Internal: `.venv/bin/python -m pytest tests/cmis -q` -> `48 passed`.
+- OpenCMIS: `run-20260508T153316Z` in
+  `/tmp/open-cmis-tck-kontextual-wp14-20260508T153146Z`.
+- Maturity score: `19.05`; coverage remains `2/9` groups.
+- `repository-type` is now partial/warning; `object-content` remains
+  infrastructure-blocked by concrete CRUD/content edge cases.
+
+Current external frontier:
+
+- `getObjectByPath` path-segment failures in child checks.
+- No-content document content-stream semantics.
+- Operation-context/property filter trimming, especially folder `cmis:path`.
+- `bulkUpdate`, `deleteContent`, and change-token unsupported-action handling.

+
+Implemented in this pass:
+
+- Correct `relativePathSegment` behavior for document parents.
+- Browser Binding operation-context trimming for property filters, allowable
+  actions, ACLs, and path segments.
+- Total-count `numItems` semantics for Browser Binding children.
+- Stable adapter-managed folder object IDs across folder rename/update.
+- Nullable no-content document stream properties and empty compatibility streams.
+- Range-aware content responses with sliced bodies, `206`, and `Content-Range`.
+- `setContent` and `deleteContent` Browser Binding action aliases.

+Latest verification:
+
+- Internal focused CMIS tests: `20 passed`.
+- Full suite: `160 passed, 14 skipped`.

+
+Current external frontier:
+
+- CMIS-specific exception mapping for invalid type operations.
+- `bulkUpdateProperties` remains unsupported.
+- `deleteContentStream` needs stronger representation-removal/tombstone

+- Change-token conflict behavior is not implemented.
+- `createDocumentFromSource`/copy remains unsupported.
+- Offset-zero range requests are still marked partial.
