Issues

Critical

1. QSS duplication. Resolved. The canonical QSS lives in src/Gui/Stylesheets/KindredCreate.qss. The PreferencePacks copy is now generated at build time via configure_file() in src/Gui/PreferencePacks/CMakeLists.txt. The unused resources/preferences/KindredCreate/ directory has been removed.

2. WorkbenchManipulator timing. Resolved. ZTools is no longer a workbench. Commands are registered via a deferred QTimer.singleShot(2000ms) in InitGui.py, which activates dependent workbenches first, then imports ZTools commands and installs the _ZToolsManipulator. The EditingContextResolver handles toolbar visibility based on editing context.

3. Silo shortcut persistence. Resolved. Silo_ToggleMode removed; file operations now delegate to the selected origin via the unified origin system.

High

4. Silo authentication not production-hardened. Local auth (bcrypt) works end-to-end. LDAP (FreeIPA) and OIDC (Keycloak) backends are coded but depend on infrastructure not yet deployed. FreeCAD client has Silo_Auth dock panel for login and API token management. Server has session middleware (alexedwards/scs), CSRF protection (nosurf), and role-based access control (admin/editor/viewer). Migration 009_auth.sql adds users, api_tokens, and sessions tables.

5. No unit tests. Zero test coverage for ztools and Silo FreeCAD commands. Silo Go backend also lacks tests.

6. Assembly solver datum handling is minimal. The findPlacement() fix in src/Mod/Assembly/UtilsAssembly.py extracts placement from obj.Shape.Faces[0] for PartDesign::Plane and from shape vertex for PartDesign::Point. Does not handle empty shapes or non-planar datum objects.

Medium

7. Silo_BOM requires Silo-tracked document. Depends on SiloPartNumber property. Unregistered documents show a warning with no registration path.

8. PartDesign menu insertion fragility. _ZToolsPartDesignManipulator.modifyMenuBar() inserts after PartDesign_Boolean. If upstream renames this command, insertions silently fail.

9. tangent_to_cylinder falls back to manual placement. TangentPlane MapMode requires a vertex reference not collected by the current UI.

10. delete_bom_entry() bypasses error normalization. Uses raw urllib.request instead of SiloClient._request().

11. Missing Silo icons. Three commands reference icons that don't exist: silo-tag.svg (Silo_TagProjects), silo-rollback.svg (Silo_Rollback), silo-status.svg (Silo_SetStatus). The _icon() function returns an empty string, so these commands render without toolbar icons.

Fixed (retain for reference)

12. OndselSolver Newton-Raphson convergence. NewtonRaphson::isConvergedToNumericalLimit() compared dxNorms->at(iterNo) to itself instead of dxNorms->at(iterNo - 1). This prevented convergence detection on complex assemblies, causing solver exhaustion and "grounded object moved" warnings. Fixed in Kindred fork (src/3rdParty/OndselSolver). Needs upstreaming to FreeCAD/OndselSolver.

13. Assembly solver crash on document restore. AssemblyObject::onChanged() called updateSolveStatus() when the Group property changed during document restore, triggering the solver while child objects were still deserializing (SIGSEGV). Fixed with isRestoring() and isPerformingTransaction() guards at src/Mod/Assembly/App/AssemblyObject.cpp:143.

14. DlgSettingsGeneral::applyMenuIconSize visibility. The method was private but called from StartupProcess.cpp. Fixed by moving to public (PR #49). Also required Dialog:: namespace qualifier in StartupProcess.cpp.

Next steps

1. Authentication hardening -- Deploy FreeIPA and Keycloak infrastructure. End-to-end test LDAP and OIDC flows. Harden token rotation and session expiry.

2. BOM-Assembly bridge -- Auto-populate Silo BOM from Assembly component links on save.

3. File locking -- Pessimistic locks on Silo_Open to prevent concurrent edits. Requires server-side lock table and client-side lock display.

4. Build system -- CMake install rules for mods/ submodules so packages include ztools and Silo without manual steps.

5. Test coverage -- Unit tests for ztools datum creation, Silo FreeCAD commands, and Go API endpoints.

6. QSS consolidation -- Eliminate the 3-copy QSS duplication via build-time copy or symlinks. The canonical source is resources/preferences/KindredCreate/KindredCreate.qss.

7. Update notification UI -- Display in-app notification when a new release is available (issue #30). The update checker backend is already implemented.
