+# CMIS WP-0014 OpenCMIS Evidence - 2026-05-08T13:44:32Z
+
+## Scope
+
+This note records the WP-0014 implementation evidence for raising CMIS 1.1
+Browser Binding object/content maturity in `kontextual-engine`.
+
+CMIS remains an adapter over native engine services. The work in this pass
+focused on compatibility features that map naturally to existing assets,
+representations, metadata, policy gates, and projection folders.
+
+## Implemented
+
+- Added profile-scoped adapter-managed workspace folders for CMIS-created
+  folders.
+- Added Browser Binding `createFolder`, `createDocument`, `deleteTree`, and
+  singular `parent` selector handling.
+- Added form-url-encoded and multipart Browser Binding action parsing without
+  introducing a new multipart dependency.
+- Added document/folder path projection and Browser Binding `getObjectByPath`
+  support through the root selector.
+- Tightened folder lifecycle so deleted workspace folders stop resolving as
+  phantom virtual folders.
+- Returned full folder projections from `getObjectParents`, including
+  `cmis:path` for OpenCMIS `getPaths()`.
+- Declared emitted document/folder custom properties in CMIS type metadata.
+- Included CMIS document version/read-only properties expected by common CMIS
+  clients while keeping versioning operations unsupported.
+- Prevented CMIS-authored documents from appearing multifiled when the
+  repository advertises `capabilityMultifiling=false`.
+- Corrected document allowable actions so non-folder objects do not advertise
+  `canGetFolderParent`.
+
+## Local Verification
+
+Focused CMIS tests:
+
+```bash
+.venv/bin/python -m pytest tests/cmis --perf-history-disable
+```
+
+Result:
+
+- `47 passed`
+
+## OpenCMIS Run
+
+Command shape:
+
+```bash
+cd /home/worsch/guide-board
+source /home/worsch/open-cmis-tck/.local/toolchains/env.sh
+PYTHONPATH=src python3 -m guide_board \
+  --extension-dir ../open-cmis-tck \
+  run \
+  --target /tmp/kontextual-cmis-compat-8010.json \
+  --assessment ../open-cmis-tck/profiles/assessments/cmis-browser-baseline.json \
+  --output-dir /tmp/open-cmis-tck-kontextual-wp14-20260508T134432Z
+```
+
+Result:
+
+- Run ID: `run-20260508T134448Z`
+- Run directory: `/tmp/open-cmis-tck-kontextual-wp14-20260508T134432Z`
+- Harness status: `infrastructure_error`
+- Scorecard: `/tmp/open-cmis-tck-kontextual-wp14-20260508T134432Z/reports/cmis-maturity-scorecard.md`
+
+The scorecard still classifies the two mapped groups as infrastructure-blocked,
+but the raw OpenCMIS output shows meaningful progress inside the test groups.
+
+## Evidence Progression
+
+Earlier WP-0014 runs stopped at foundational Browser Binding gaps:
+
+- Unsupported `parent` selector.
+- Folder custom properties declared by type metadata but missing from root
+  folder objects.
+- Multipart `createDocument` action bodies not parsed because multipart
+  boundaries were lowercased.
+- `deleteTree` unsupported during OpenCMIS cleanup.
+- CMIS-created folders still resolving after deletion as generic virtual
+  folders.
+- Document projections exposing undeclared custom fields such as
+  `kontextual:assetId`.
+- OpenCMIS `getPaths()` failing because parent folder objects lacked
+  `cmis:path`.
+
+The final run reaches deeper object/content behaviors:
+
+- Repository info checks pass.
+- Root folder test passes.
+- Type definition enumeration runs.
+- Document creation proceeds far enough to exercise update, move, delete-tree,
+  operation-context, and async object lookup tests.
+- Delete-tree tests create many documents and report MIME warnings rather than
+  basic object-creation failures.
+
+## Current Frontier
+
+Remaining natural CMIS maturity items:
+
+- Browser Binding action aliases: OpenCMIS sends `cmisaction=update` and
+  `cmisaction=move`; we currently expose `updateProperties` and do not support
+  move.
+- Operation-context fidelity: `getObject()` and `getChildren()` currently
+  return more properties, ACLs, allowable actions, and path segments than
+  requested.
+- MIME normalization: OpenCMIS expects `text/plain`; some created streams are
+  reported as `text/plain; charset=utf-8`.
+- Async `getObjectByPath`: OpenCMIS async child/folder checks still hit a
+  `Not Found` path lookup case.
+- Copy/move and secondary type mutation remain unsupported unless a later
+  workplan admits them.
+
+## Interpretation
+
+The adapter foundation is sounder after this pass. The failures are no longer
+basic session, repository, folder-creatable, multipart action parsing, or parent
+path hydration issues. They are now mostly CMIS client polish around action
+aliases, response filtering, and optional ECM behaviors.
+
+WP-0014 should remain active for follow-up maturity work, but the core
+folder/object-content compatibility foundation is implemented.
