 ## What is Kindred Create?
 
-Kindred Create is a fork of [FreeCAD](https://www.freecad.org) that adds integrated tooling for professional engineering workflows. It ships a context-aware UI system, two addon command sets, a purpose-built dark theme, and a pluggable file origin layer on top of FreeCAD's parametric modeling core.
+Kindred Create is a fork of [FreeCAD](https://www.freecad.org) that adds integrated tooling for professional engineering workflows. It ships a context-aware UI system, addon workbenches, a purpose-built dark theme, and a pluggable file origin layer on top of FreeCAD's parametric modeling core.
 
 **Editing context system** -- The UI adapts to what you are editing. An `EditingContextResolver` tracks the active document, view, and in-edit object, then shows or hides toolbars automatically. Built-in contexts cover sketcher editing, assembly editing, PartDesign features/bodies, spreadsheets, and idle states. Addons register their own contexts through a Python API. A color-coded breadcrumb bar in the 3D viewport shows the current editing path.
 
-**ztools** -- A command provider that injects velocity-focused tools into FreeCAD's native PartDesign, Assembly, and Spreadsheet workbenches. Adds custom datum creation (planes, axes, points with 15 attachment modes), pattern tools for assemblies, an enhanced pocket with flip-side cutting, and spreadsheet formatting commands. Rather than running as a separate workbench, ztools commands appear contextually via the editing context system.
+**Gears** -- A parametric gear generation workbench for creating involute spur gears, helical gears, and other gear profiles directly within FreeCAD assemblies.
 
 **Silo** -- A parts lifecycle management system for managing CAD files, part numbers, revisions, and bills of materials across teams. Includes a Go REST API server backed by PostgreSQL and MinIO, with FreeCAD commands for opening, saving, and syncing files directly from the application. A unified origin system integrates Silo file operations (New, Open, Save, Commit, Pull, Push) into the standard File toolbar and menu across all workbenches. Dock panels provide authentication, real-time database activity via SSE, and a custom start page that replaces the default FreeCAD landing.

 ### Addon integration
 
-Addons in `mods/` are loaded by a manifest-driven loader (`src/Mod/Create/addon_loader.py`). Each addon provides a `package.xml` with `<kindred>` extensions declaring version bounds, load priority, and dependencies. The loader resolves dependencies via topological sort and loads addons in order: **sdk** (0) → **ztools** (50) → **silo** (60).

 Addons call platform APIs through the **kindred-addon-sdk** (`mods/sdk/kindred_sdk/`) rather than `FreeCADGui.*` internals directly. The SDK provides stable wrappers for editing contexts, theme tokens, FileOrigin registration, and dock panels.

-
-## 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.** `UtilsAssembly.findPlacement()` handles standard shapes (faces, edges, vertices) and `App::Line` origin objects. It does not extract placement from `PartDesign::Plane` or `PartDesign::Point` datum objects — when no element is selected, it returns a default `App.Placement()`. This means assembly joints referencing datum planes/points may produce incorrect placement.
-
-### 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.**~~ Resolved. `delete_bom_entry()` uses `self._request("DELETE", ...)` which routes through `SiloClient._request()` with proper error handling.
-
-11. ~~**Missing Silo icons.**~~ Resolved. All three icons now exist: `silo-tag.svg`, `silo-rollback.svg`, `silo-status.svg` in `mods/silo/freecad/resources/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. See `docs/BOM_MERGE.md` for specification.
-
-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**~~ Done. CMake install rules in `src/Mod/Create/CMakeLists.txt` handle all `mods/` submodules.
-
-5. **Test coverage** -- Unit tests for ztools datum creation, Silo FreeCAD commands, and Go API endpoints.
-
-6. ~~**QSS consolidation**~~ Done. Canonical QSS is `src/Gui/Stylesheets/KindredCreate.qss`; PreferencePacks copy generated at build time via `configure_file()`.
-
-7. **Update notification UI** -- Display in-app notification when a new release is available (issue #30). The update checker backend (`update_checker.py`) runs at startup; notification UI still needed.
-
-8. **KC file format completion** -- Populate `silo_instance` and `revision_hash` in manifest.json. Implement write-back for history.json, approvals.json, dependencies.json. See `docs/KC_SPECIFICATION.md`.
-
-9. **ztools SDK migration** -- Add `<kindred>` metadata to `mods/ztools/package.xml` (load priority, version bounds, SDK dependency). Migrate `InitGui.py` to use `kindred_sdk` APIs for context/overlay registration.
-
-10. **DAG cross-item edges** -- Assembly constraints referencing geometry in child parts should populate `dag_cross_edges`. Deferred until assembly constraint model is finalized.

-# DAG Client Integration Contract
-
-**Status:** Draft
-**Last Updated:** 2026-02-13
-
-This document describes what silo-mod and Headless Create runners need to implement to integrate with the Silo dependency DAG and worker system.
-
----
-
-## 1. Overview
-
-The DAG system has two client-side integration points:
-
-1. **silo-mod workbench** (desktop) -- pushes DAG data to Silo on save or revision create.
-2. **silorunner + silo-mod** (headless) -- extracts DAGs, validates features, and exports geometry as compute jobs.
-
-Both share the same Python codebase in the silo-mod repository. Desktop users call the code interactively; runners call it headlessly via `create --console`.
-
----
-
-## 2. DAG Sync Payload
-
-Clients push feature trees to Silo via:
-
-```
-PUT /api/items/{partNumber}/dag
-Authorization: Bearer <user_token or runner_token>
-Content-Type: application/json
-```
-
-### 2.1 Request Body
-
-```json
-{
-  "revision_number": 3,
-  "nodes": [
-    {
-      "node_key": "Sketch001",
-      "node_type": "sketch",
-      "properties_hash": "a1b2c3d4e5f6...",
-      "metadata": {
-        "label": "Base Profile",
-        "constraint_count": 12
-      }
-    },
-    {
-      "node_key": "Pad001",
-      "node_type": "pad",
-      "properties_hash": "f6e5d4c3b2a1...",
-      "metadata": {
-        "label": "Main Extrusion",
-        "length": 25.0
-      }
-    }
-  ],
-  "edges": [
-    {
-      "source_key": "Sketch001",
-      "target_key": "Pad001",
-      "edge_type": "depends_on"
-    }
-  ]
-}
-```
-
-### 2.2 Field Reference
-
-**Nodes:**
-
-| Field | Type | Required | Description |
-|-------|------|----------|-------------|
-| `node_key` | string | yes | Unique within item+revision. Use Create's internal object name (e.g. `Sketch001`, `Pad003`). |
-| `node_type` | string | yes | One of: `sketch`, `pad`, `pocket`, `fillet`, `chamfer`, `constraint`, `body`, `part`, `datum`. |
-| `properties_hash` | string | no | SHA-256 hex digest of the node's parametric inputs. Used for memoization. |
-| `validation_state` | string | no | One of: `clean`, `dirty`, `validating`, `failed`. Defaults to `clean`. |
-| `metadata` | object | no | Arbitrary key-value pairs for display or debugging. |
-
-**Edges:**
-
-| Field | Type | Required | Description |
-|-------|------|----------|-------------|
-| `source_key` | string | yes | The node that is depended upon. |
-| `target_key` | string | yes | The node that depends on the source. |
-| `edge_type` | string | no | One of: `depends_on` (default), `references`, `constrains`. |
-
-**Direction convention:** Edges point from dependency to dependent. If Pad001 depends on Sketch001, the edge is `source_key: "Sketch001"`, `target_key: "Pad001"`.
-
-### 2.3 Response
-
-```json
-{
-  "synced": true,
-  "node_count": 15,
-  "edge_count": 14
-}
-```
-
----
-
-## 3. Computing properties_hash
-
-The `properties_hash` enables memoization -- if a node's inputs haven't changed since the last validation, it can be skipped. Computing it:
-
-```python
-import hashlib
-import json
-
-def compute_properties_hash(feature_obj):
-    """Hash the parametric inputs of a Create feature."""
-    inputs = {}
-
-    if feature_obj.TypeId == "Sketcher::SketchObject":
-        # Hash geometry + constraints
-        inputs["geometry_count"] = feature_obj.GeometryCount
-        inputs["constraint_count"] = feature_obj.ConstraintCount
-        inputs["geometry"] = str(feature_obj.Shape.exportBrep())
-    elif feature_obj.TypeId == "PartDesign::Pad":
-        inputs["length"] = feature_obj.Length.Value
-        inputs["type"] = str(feature_obj.Type)
-        inputs["reversed"] = feature_obj.Reversed
-        inputs["sketch"] = feature_obj.Profile[0].Name
-    # ... other feature types
-
-    canonical = json.dumps(inputs, sort_keys=True)
-    return hashlib.sha256(canonical.encode()).hexdigest()
-```
-
-The exact inputs per feature type are determined by what parametric values affect the feature's geometry. Include anything that, if changed, would require recomputation.
-
----
-
-## 4. Feature Tree Walking
-
-To extract the DAG from a Create document:
-
-```python
-import FreeCAD
-
-def extract_dag(doc):
-    """Walk a Create document and return nodes + edges."""
-    nodes = []
-    edges = []
-
-    for obj in doc.Objects:
-        # Skip non-feature objects
-        if not hasattr(obj, "TypeId"):
-            continue
-
-        node_type = classify_type(obj.TypeId)
-        if node_type is None:
-            continue
-
-        nodes.append({
-            "node_key": obj.Name,
-            "node_type": node_type,
-            "properties_hash": compute_properties_hash(obj),
-            "metadata": {
-                "label": obj.Label,
-                "type_id": obj.TypeId,
-            }
-        })
-
-        # Walk dependencies via InList (objects this one depends on)
-        for dep in obj.InList:
-            if hasattr(dep, "TypeId") and classify_type(dep.TypeId):
-                edges.append({
-                    "source_key": dep.Name,
-                    "target_key": obj.Name,
-                    "edge_type": "depends_on",
-                })
-
-    return nodes, edges
-
-
-def classify_type(type_id):
-    """Map Create TypeIds to DAG node types."""
-    mapping = {
-        "Sketcher::SketchObject": "sketch",
-        "PartDesign::Pad": "pad",
-        "PartDesign::Pocket": "pocket",
-        "PartDesign::Fillet": "fillet",
-        "PartDesign::Chamfer": "chamfer",
-        "PartDesign::Body": "body",
-        "Part::Feature": "part",
-        "Sketcher::SketchConstraint": "constraint",
-    }
-    return mapping.get(type_id)
-```
-
----
-
-## 5. When to Push DAG Data
-
-Push the DAG to Silo in these scenarios:
-
-| Event | Trigger | Who |
-|-------|---------|-----|
-| User saves in silo-mod | On save callback | Desktop silo-mod workbench |
-| User creates a revision | After `POST /api/items/{pn}/revisions` succeeds | Desktop silo-mod workbench |
-| Runner extracts DAG | After `create-dag-extract` job completes | silorunner via `PUT /api/runner/jobs/{id}/dag` |
-| Runner validates | After `create-validate` job, push updated validation states | silorunner via `PUT /api/runner/jobs/{id}/dag` |
-
----
-
-## 6. Runner Entry Points
-
-silo-mod must provide these Python entry points for headless invocation:
-
-### 6.1 silo.runner.dag_extract
-
-Extracts the feature DAG from a Create file and writes it as JSON.
-
-```python
-# silo/runner.py
-
-def dag_extract(input_path, output_path):
-    """
-    Extract feature DAG from a Create file.
-
-    Args:
-        input_path: Path to the .kc (Kindred Create) file.
-        output_path: Path to write the JSON output.
-
-    Output JSON format:
-    {
-        "nodes": [...],  // Same format as DAG sync payload
-        "edges": [...]
-    }
-    """
-    doc = FreeCAD.openDocument(input_path)
-    nodes, edges = extract_dag(doc)
-
-    with open(output_path, 'w') as f:
-        json.dump({"nodes": nodes, "edges": edges}, f)
-
-    FreeCAD.closeDocument(doc.Name)
-```
-
-### 6.2 silo.runner.validate
-
-Rebuilds all features and reports pass/fail per node.
-
-```python
-def validate(input_path, output_path):
-    """
-    Validate a Create file by rebuilding all features.
-
-    Output JSON format:
-    {
-        "valid": true/false,
-        "nodes": [
-            {
-                "node_key": "Pad001",
-                "state": "clean",       // or "failed"
-                "message": null,        // error message if failed
-                "properties_hash": "..."
-            }
-        ]
-    }
-    """
-    doc = FreeCAD.openDocument(input_path)
-    doc.recompute()
-
-    results = []
-    all_valid = True
-    for obj in doc.Objects:
-        if not hasattr(obj, "TypeId"):
-            continue
-        node_type = classify_type(obj.TypeId)
-        if node_type is None:
-            continue
-
-        state = "clean"
-        message = None
-        if hasattr(obj, "isValid") and not obj.isValid():
-            state = "failed"
-            message = f"Feature {obj.Label} failed to recompute"
-            all_valid = False
-
-        results.append({
-            "node_key": obj.Name,
-            "state": state,
-            "message": message,
-            "properties_hash": compute_properties_hash(obj),
-        })
-
-    with open(output_path, 'w') as f:
-        json.dump({"valid": all_valid, "nodes": results}, f)
-
-    FreeCAD.closeDocument(doc.Name)
-```
-
-### 6.3 silo.runner.export
-
-Exports geometry to STEP, IGES, or other formats.
-
-```python
-def export(input_path, output_path, format="step"):
-    """
-    Export a Create file to an external format.
-
-    Args:
-        input_path: Path to the .kc file.
-        output_path: Path to write the exported file.
-        format: Export format ("step", "iges", "stl", "obj").
-    """
-    doc = FreeCAD.openDocument(input_path)
-
-    import Part
-    shapes = [obj.Shape for obj in doc.Objects if hasattr(obj, "Shape")]
-    compound = Part.makeCompound(shapes)
-
-    format_map = {
-        "step": "STEP",
-        "iges": "IGES",
-        "stl": "STL",
-        "obj": "OBJ",
-    }
-
-    Part.export([compound], output_path)
-    FreeCAD.closeDocument(doc.Name)
-```
-
----
-
-## 7. Headless Invocation
-
-The `silorunner` binary shells out to Create (with silo-mod installed):
-
-```bash
-# DAG extraction
-create --console -e "from silo.runner import dag_extract; dag_extract('/tmp/job/part.kc', '/tmp/job/dag.json')"
-
-# Validation
-create --console -e "from silo.runner import validate; validate('/tmp/job/part.kc', '/tmp/job/result.json')"
-
-# Export
-create --console -e "from silo.runner import export; export('/tmp/job/part.kc', '/tmp/job/output.step', 'step')"
-```
-
-**Prerequisites:** The runner host must have:
-- Headless Create installed (Kindred's fork of FreeCAD)
-- silo-mod installed as a Create addon (so `from silo.runner import ...` works)
-- No display server required -- `--console` mode is headless
-
----
-
-## 8. Validation Result Handling
-
-After a runner completes a `create-validate` job, it should:
-
-1. Read the result JSON.
-2. Push updated validation states via `PUT /api/runner/jobs/{jobID}/dag`:
-
-```json
-{
-  "revision_number": 3,
-  "nodes": [
-    {"node_key": "Sketch001", "node_type": "sketch", "validation_state": "clean", "properties_hash": "abc..."},
-    {"node_key": "Pad001", "node_type": "pad", "validation_state": "failed", "properties_hash": "def..."}
-  ],
-  "edges": [
-    {"source_key": "Sketch001", "target_key": "Pad001"}
-  ]
-}
-```
-
-3. Complete the job via `POST /api/runner/jobs/{jobID}/complete` with the summary result.
-
----
-
-## 9. SSE Events
-
-Clients should listen for these events on `GET /api/events`:
-
-| Event | Payload | When |
-|-------|---------|------|
-| `dag.updated` | `{item_id, part_number, revision_number, node_count, edge_count}` | After any DAG sync |
-| `dag.validated` | `{item_id, part_number, valid, failed_count}` | After validation completes |
-| `job.created` | `{job_id, definition_name, trigger, item_id}` | Job auto-triggered or manually created |
-| `job.claimed` | `{job_id, runner_id, runner}` | Runner claims a job |
-| `job.progress` | `{job_id, progress, message}` | Runner reports progress |
-| `job.completed` | `{job_id, runner_id}` | Job finishes successfully |
-| `job.failed` | `{job_id, runner_id, error}` | Job fails |
-| `job.cancelled` | `{job_id, cancelled_by}` | Job cancelled by user |
-
----
-
-## 10. Cross-Item Edges
-
-For assembly constraints that reference geometry in child parts (e.g. a mate constraint between two parts), use the `dag_cross_edges` table. These edges bridge the BOM DAG and the feature DAG.
-
-Cross-item edges are **not** included in the standard `PUT /dag` sync. They will be managed through a dedicated endpoint in a future iteration once the assembly constraint model in Create/silo-mod is finalized.
-
-For now, the DAG sync covers intra-item dependencies only. Assembly-level interference detection uses the BOM DAG (`relationships` table) combined with per-item feature DAGs.

-## Recent Changes (This Session)
-
-### Assembly Solver Fix
-- `610fd43` — PartDesign datum planes (including ZTools datums) now work
-  correctly as joint references in Assembly. `findPlacement()` in
-  `src/Mod/Assembly/UtilsAssembly.py` extracts geometry from
-  `PartDesign::Plane` and `PartDesign::Point` objects instead of returning
-  zero placements.
-
-### ZTools Bug Fixes
-- `665bdb2` — Three fixes in the ztools submodule:
-  - Removed `int()` wrapper from `getStandardButtons()` (Qt6/PySide6
-    compatibility — `StandardButton` enum is not int-castable).
-  - Guarded `_setup_ztools_viewprovider()` against C++ ViewProviders
-    that lack a `Proxy` attribute (`PartDesign::Plane` uses
-    `ViewProviderDatumPlane`, pure C++).
-  - Changed `setEditorMode(prop, 2)` to `setPropertyStatus(prop, "Hidden")`
-    for persistent attachment property hiding across save/reload.
-
-### ZTools Parametric Datums via AttachExtension
-- `2c716b4` — ZTools datum planes now leverage FreeCAD's built-in
-  `Part::AttachExtension` for automatic parametric updates. Instead of
-  `MapMode = "Deactivated"` with manual placement, each datum type maps to a
-  vanilla `MapMode` (`FlatFace`, `ThreePointsPlane`, `NormalToEdge`, etc.)
-  with appropriate `AttachmentSupport` and `AttachmentOffset`. Datums update
-  automatically when source geometry changes on recompute.
-
-### Stylesheet Fixes (Uncommitted — Staged)
-- **Tree branch indicators**: Created `branch_closed.svg` and
-  `branch_open.svg` in `images_dark-light/` with Catppuccin `#cdd6f4`
-  chevrons. Added `QTreeView::branch` image rules for expand/collapse states.
-- **Spinbox/combobox arrows**: Synced all three QSS copies so the CSS
-  border-triangle arrow fix (previously only in `resources/preferences/`)
-  now applies at runtime via `src/Gui/Stylesheets/KindredCreate.qss`.
-- **Header clipping**: Added `min-height: 20px` to `QHeaderView::section`.
-- **QSS sync**: All four copies (`resources/preferences/`, `src/Gui/Stylesheets/`,
-  `src/Gui/PreferencePacks/`, `mods/ztools/CatppuccinMocha/`) are now
-  byte-identical. Merged dock widget padding and spreadsheet cell editor
-  styling improvements that existed only in the Stylesheets copy.
-
-### ZTools-PartDesign Merge (Uncommitted — Staged)
-- `_ZToolsPartDesignManipulator` in `mods/ztools/ztools/InitGui.py` uses
-  `Gui.addWorkbenchManipulator()` to inject ZTools commands into PartDesign's
-  C++ toolbars:
-  - `ZTools_DatumCreator` + `ZTools_DatumManager` → "Part Design Helper Features"
-  - `ZTools_EnhancedPocket` → "Part Design Modeling Features"
-  - `ZTools_RotatedLinearPattern` → "Part Design Transformation Features"
-  - Same commands also inserted into the Part Design menu after `PartDesign_Boolean`.
-
-### Silo Enhancements (Uncommitted — Staged)
-- **File menu integration**: `SiloMenuManipulator` in `src/Mod/Create/InitGui.py`
-  injects `Silo_New`, `Silo_Open`, `Silo_Save`, `Silo_Commit`, `Silo_Pull`,
-  `Silo_Push`, and `Silo_BOM` into the File menu across all workbenches.
-- **Toolbar toggle**: `Silo_ToggleMode` checkable command swaps `Ctrl+O/S/N`
-  between standard FreeCAD file commands and Silo equivalents. Appended to the
-  global File toolbar via the manipulator.
-- **SSL certificate browsing**: Settings dialog now includes a file browser for
-  custom CA certificates (`SslCertPath` preference). `_get_ssl_context()` loads
-  the custom cert before system CAs.
-- **BOM integration**: Upstream BOM feature (`Silo_BOM` command with tabbed
-  dialog — BOM + Where Used) merged with local changes and added to the
-  Create File menu manipulator.

-## Potential Issues
-
-### Critical
-
-1. **Three QSS copies can drift again.** The canonical source is
-   `resources/preferences/KindredCreate/KindredCreate.qss`. The other copies
-   (`src/Gui/Stylesheets/`, `src/Gui/PreferencePacks/`, `mods/ztools/CatppuccinMocha/`)
-   must be kept in sync manually. Consider a build step or symlinks to
-   eliminate duplication.
-
-2. **WorkbenchManipulator command registration timing.** The
-   `_ZToolsPartDesignManipulator` appends commands by name (e.g.
-   `ZTools_DatumCreator`). If the ZTools workbench has not been initialized
-   (first activation) when the user switches to PartDesign, the commands may
-   not be registered yet. The `Create/InitGui.py` `exec()` loads the
-   workbench class but `Initialize()` only runs on first activation. The
-   manipulator API tolerates missing commands silently (toolbar append
-   returns without error), but the buttons won't appear until ZTools
-   initializes. Mitigation: force-activate ZToolsWorkbench during Create
-   module load, or defer manipulator installation.
-
-3. **Silo toggle mode shortcut persistence.** `_swap_shortcuts()` stores
-   original shortcuts in a module-level dict (`_original_shortcuts`). If
-   FreeCAD crashes with Silo mode ON, the original shortcuts are lost and
-   standard commands will have no keyboard shortcuts on next launch. Consider
-   persisting original shortcuts to preferences.
-
-### High
-
-4. **Silo has no authentication.** All API endpoints are publicly accessible.
-   Required before multi-user deployment. See
-   `mods/silo/docs/REPOSITORY_STATUS.md` for full list.
-
-5. **No unit tests for silo FreeCAD commands or ztools.** Python code has zero
-   test coverage. The Go backend also lacks tests per the silo status report.
-
-6. **Assembly solver `findPlacement()` geometry extraction is minimal.** The
-   fix at `UtilsAssembly.py:1006` extracts placement from `obj.Shape.Faces[0]`
-   for `PartDesign::Plane`. This works for planar datums but does not handle
-   edge cases like empty shapes or non-planar datum objects.
-
-### Medium
-
-7. **`Silo_BOM` depends on `get_tracked_object()`** which looks for a
-   `SiloPartNumber` property on document objects. Documents not registered
-   with Silo show a warning dialog. The UX could be improved with a
-   one-click registration flow from the BOM dialog.
-
-8. **`_ZToolsPartDesignManipulator.modifyMenuBar()` inserts after
-   `PartDesign_Boolean`.** If upstream FreeCAD renames or removes this
-   command, the menu insertions silently fail. The toolbar appends (by
-   toolbar name) are more robust.
-
-9. **ZTools `plane_tangent_to_cylinder` falls back to manual placement**
-   because the TangentPlane MapMode requires a vertex reference not currently
-   collected by the UI. This is the only datum type that does not benefit
-   from automatic parametric updates.
-
-10. **Silo `delete_bom_entry()` uses raw `urllib.request`** instead of the
-    `_request()` helper method on `SiloClient`. This bypasses error
-    normalization. Should be refactored to use `self._request("DELETE", ...)`.

-
-## Silo Integration Path
-
-Based on `mods/silo/docs/REPOSITORY_STATUS.md` and the existing
-`docs/INTEGRATION_PLAN.md`, the integration path forward is:
-
-### Completed
-- Addon auto-loading via `src/Mod/Create/InitGui.py`
-- Global File menu injection via `WorkbenchManipulator`
-- Toolbar toggle for Silo mode (shortcut swapping)
-- SSL certificate configuration for internal CAs
-- BOM command integrated into File menu
-
-### Next Steps
-1. **Authentication** — LDAP/FreeIPA integration for multi-user. Silo server
-   needs auth middleware; FreeCAD client needs credential storage in preferences.
-2. **BOM-Assembly bridge** — Auto-populate Silo BOM from FreeCAD Assembly
-   component links. When a user saves an assembly, extract child part numbers
-   from `Assembly_InsertLink` objects and sync to Silo BOM.
-3. **File locking** — Pessimistic locks on checkout (`Silo_Open`) to prevent
-   concurrent edits. Requires server-side lock table and client-side
-   lock-status display.
-4. **Status bar integration** — Show current Silo item part number, revision,
-   and sync status in FreeCAD's status bar. Use
-   `FreeCADGui.getMainWindow().statusBar()`.
-5. **Build system** — CMake install rules for `mods/` submodules so `.deb`
-   packages include ztools and silo without manual intervention.

-# ztools
-
-ztools is a pure-Python FreeCAD workbench that consolidates part design, assembly, and sketcher tools into a single unified interface. It is the **default workbench** when Kindred Create launches.
-
-- **Submodule path:** `mods/ztools/`
-- **Source:** `git.kindred-systems.com/forbes/ztools`
-- **Stats:** 6,400+ lines of code, 24+ command classes, 33 custom icons, 17 toolbars
-
-## Commands
-
-### Datum Creator (`ZTools_DatumCreator`)
-
-Creates datum geometry (planes, axes, points) with 16 creation modes. The task panel auto-detects the geometry type from your selection and offers appropriate modes. Supports custom naming, spreadsheet linking, and body- or document-level creation.
-
-### Datum Manager (`ZTools_DatumManager`)
-
-Manages existing datums. (Stub — planned for Phase 1, Q1 2026.)
-
-### Enhanced Pocket (`ZTools_EnhancedPocket`)
-
-Extends FreeCAD's Pocket feature with **Flip Side to Cut** — a SOLIDWORKS-style feature that removes material *outside* the sketch profile rather than inside. Uses a Boolean Common operation internally. Supports all standard pocket types: Dimension, Through All, To First, Up To Face, Two Dimensions. Taper angle is supported for standard pockets (disabled for flipped).
-
-### Rotated Linear Pattern (`ZTools_RotatedLinearPattern`)
-
-Creates a linear pattern with incremental rotation per instance. Configure direction, spacing, number of occurrences, and cumulative or per-instance rotation. Source components are automatically hidden.
-
-### Assembly Linear Pattern (`ZTools_AssemblyLinearPattern`)
-
-Creates linear patterns of assembly components. Supports multi-component selection, direction vectors, total length or spacing modes, and creation as Links (recommended) or copies. Auto-detects the parent assembly.
-
-### Assembly Polar Pattern (`ZTools_AssemblyPolarPattern`)
-
-Creates polar (circular) patterns of assembly components. Supports custom or preset axes (X/Y/Z), full circle or custom angle, center point definition, and creation as Links or copies.
-
-### Spreadsheet Formatting (9 commands)
-
-| Command | Action |
-|---------|--------|
-| `ZTools_SpreadsheetStyleBold` | Toggle bold |
-| `ZTools_SpreadsheetStyleItalic` | Toggle italic |
-| `ZTools_SpreadsheetStyleUnderline` | Toggle underline |
-| `ZTools_SpreadsheetAlignLeft` | Left align |
-| `ZTools_SpreadsheetAlignCenter` | Center align |
-| `ZTools_SpreadsheetAlignRight` | Right align |
-| `ZTools_SpreadsheetBgColor` | Background color picker |
-| `ZTools_SpreadsheetTextColor` | Text color picker |
-| `ZTools_SpreadsheetQuickAlias` | Auto-create aliases from row/column labels |
-

-| Circle Center | Point at the center of a circular or arc edge | Circular edge |
-
-## PartDesign injection
-
-ztools registers a `_ZToolsPartDesignManipulator` that hooks into the PartDesign workbench at startup. This injects the following commands into PartDesign's toolbars and menus:
-
-| PartDesign toolbar | Injected command |
-|--------------------|-----------------|
-| Part Design Helper Features | `ZTools_DatumCreator`, `ZTools_DatumManager` |
-| Part Design Modeling Features | `ZTools_EnhancedPocket` |
-| Part Design Transformation Features | `ZTools_RotatedLinearPattern` |
-
-The manipulator is registered in `InitGui.py` when the Create bootstrap module loads addon workbenches.
