+# Adapter Compatibility Assessment: Qt5 → Qt6
+
+**Date**: 2026-03-12
+**Status**: ✅ Assessment Complete
+**Task**: B2 - Assess adapter plugin compatibility with Qt6
+
+---
+
+## Executive Summary
+
+The current `ovos-legacy-mycroft-gui-plugin` adapter (Qt5/Tornado) **cannot simultaneously support both Qt5 and Qt6 clients without significant architectural changes**. The breaking changes in C++ media APIs and QML syntax require either:
+
+1. **Dual support implementation** (conditional compilation + separate implementations)
+2. **Adapter versioning** (separate v1.x for Qt5, v2.x for Qt6)
+3. **Hard cutover** to Qt6 (drop Qt5 support entirely)
+
+---
+
+## Adapter Component Compatibility Matrix
+
+| Component | Qt5 Support | Qt6 Support | Status | Effort to Fix |
+|-----------|:-----------:|:-----------:|--------|:-------------:|
+| **Tornado WebSocket server** | ✅ Yes | ✅ Yes | Works as-is | 🟢 None |
+| **QML template serving** | ✅ Yes | ⚠️ Conditional | Needs version detection | 🟡 Low |
+| **Media handling (audio/video)** | ✅ Yes | ❌ No | APIs completely changed | 🔴 High |
+| **GUI page routing** | ✅ Yes | ✅ Yes | Protocol unchanged | 🟢 None |
+| **Session data management** | ✅ Yes | ✅ Yes | Protocol unchanged | 🟢 None |
+
+---
+
+## Critical Breaking Changes
+
+### 1. Audio Processing (QAudioProbe → QAudioSource)
+
+**Qt5**: Uses `QAudioProbe` for spectrum analysis and audio metadata
+**Qt6**: Uses `QAudioSource` (different API, incompatible)
+
+**Impact**: Any audio visualization (waveform, equalizer, spectrum) must be rewritten.
+
+**File**: `ovos-legacy-mycroft-gui-plugin/mediaservice.cpp`
+
+---
+
+### 2. Video Rendering (QAbstractVideoSurface → QVideoSink)
+
+**Qt5**: Video rendered via `QAbstractVideoSurface` property binding
+**Qt6**: Video rendered via `QVideoSink` (property and internal names changed)
+
+**Impact**: Video playback requires different property names and callback mechanisms.
+
+**File**: `ovos-legacy-mycroft-gui-plugin/mediaservice.h` (property definitions)
+
+---
+
+### 3. QML Import Versioning
+
+**Qt5 QML files**:
+```qml
+import QtQuick 2.4
+import QtMultimedia 5.9
+```
+
+**Qt6 QML files**:
+```qml
+import QtQuick 2.15
+import QtMultimedia  // unversioned!
+```
+
+**Impact**: QML files must be separate per Qt version; cannot share implementation.
+
+**Files**: `ovos-legacy-mycroft-gui-plugin/qml/*.qml`
+
+---
+
+### 4. Build System (KF5 → KF6 incompatible)
+
+**Qt5**: Requires `find_package(KF5 REQUIRED)` with `qt5_add_resources()`
+**Qt6**: Requires `find_package(KF6 REQUIRED)` with `qt6_add_resources()`
+
+**Impact**: CMakeLists.txt must conditionally detect Qt version and include appropriate frameworks.
+
+**File**: `ovos-legacy-mycroft-gui-plugin/CMakeLists.txt`
+
+---
+
+## Assessment: Can Both Clients Connect Simultaneously?
+
+**Question**: Can a single adapter instance handle both Qt5 and Qt6 GUI clients on the same system?
+
+**Answer**: ❌ **No, without dual support implementation**
+
+**Reasoning**:
+1. The adapter loads compiled C++ media handlers at startup (QAudioProbe OR QAudioSource, not both)
+2. QML files must match the version being served (can't dynamically load both 5.9 and 2.15 imports)
+3. WebSocket protocol is version-agnostic, but QML assets served depend on build target
+
+**Workaround**: Build two adapter instances:
+- `ovos-legacy-mycroft-gui-adapter-qt5` (current)
+- `ovos-legacy-mycroft-gui-adapter-qt6` (new)
+
+Each serves only its target Qt version.
+
+---
+
+## Recommended Path Forward
+
+### Option A: Dual Support (Parallel Qt5 + Qt6)
+
+**Effort**: 🔴 High (40-60 hours)
+
+**Pros**:
+- Single codebase for both versions
+- Gradual migration path
+- No breaking changes to production
+
+**Cons**:
+- Maintain two implementations of media code
+- Larger binary size
+- More complex CI testing matrix
+
+**Recommendation**: ✅ **Best long-term if team has capacity**
+
+---
+
+### Option B: Adapter Versioning (Qt5 v1.x → Qt6 v2.x)
+
+**Effort**: 🟡 Medium (20-30 hours)
+
+**Pros**:
+- Clean separation (v1 for Qt5, v2 for Qt6)
+- Simpler individual codebases
+- Clearer messaging to users
+
+**Cons**:
+- Two releases to maintain
+- Users must explicitly install the version matching their environment
+- Confusing for new deployments ("which version do I need?")
+
+**Recommendation**: ✅ **Best for quick transition**
+
+---
+
+### Option C: Hard Cutover to Qt6
+
+**Effort**: 🟢 Low (5-10 hours)
+
+**Pros**:
+- Simplest implementation
+- Drop legacy code
+
+**Cons**:
+- Breaking change for existing Qt5 deployments
+- No migration path for users on Qt5
+- Immediate adoption pressure
+
+**Recommendation**: ❌ **Only if Qt5 support can be dropped officially**
+
+---
+
+## Implementation Roadmap (If Dual Support Selected)
+
+| Phase | Task | Duration | Dependencies |
+|-------|------|----------|:-------------:|
+| 1 | Create media provider abstraction layer | 2 days | None |
+| 2 | Implement Qt5 audio/video providers | 3 days | Phase 1 |
+| 3 | Implement Qt6 audio/video providers | 3 days | Phase 1 |
+| 4 | Add QML variants (qt5/qt6 subdirs) | 1 day | None |
+| 5 | Conditional CMakeLists.txt logic | 1 day | Phases 2-3 |
+| 6 | CI matrix testing (both versions) | 2 days | Phase 5 |
+| 7 | Documentation & migration guide | 1 day | Phases 1-6 |
+
+**Total**: 13 days (estimated)
+
+---
+
+## Conclusion
+
+The `ovos-legacy-mycroft-gui-plugin` adapter **must be redesigned for Qt6 compatibility**. The most pragmatic approach is **Option B (versioning)**: release `ovos-legacy-mycroft-gui-adapter-qt6` as a new major version, allowing users to choose based on their environment.
+
+If long-term unified support is critical, Option A (dual support) is feasible but requires architecture changes documented in `RESEARCH_Qt5_Qt6_MIGRATION.md`.

+# OVOS GUI Refactor — Design Specification
+
+**Version:** 1.0
+**Status:** Implemented — use this document to cross-check existing work
+**Scope:** GUI layer decoupling via template-based `GUIInterface` and the `opm.gui_adapter` plugin system
+
+---
+
+## 1. Motivation
+
+The previous GUI system coupled skills directly to rendering technology:
+
+- Skills shipped QML files (`gui/qt5/`) or HTML templates (`gui/py-htmx/`)
+- Skills called `self.gui.show_page("MyPage.qml")` to trigger rendering
+- Adding a new display backend (browser, terminal, Mark 1 face) required every skill to add new assets
+- Only one rendering backend could be active at a time
+
+The redesign removes all coupling between skill code and rendering technology:
+
+- Skills call **typed template methods** (`show_weather()`, `show_text()`, etc.)
+- All rendering is done by independently installed **adapter plugins** that receive these events
+- **All loaded adapters receive every event simultaneously** — multi-modal rendering is the default
+
+---
+
+## 2. High-Level Architecture
+
+```

+     Qt/QML display                         Web browser
+```
+
+**Key invariants:**
+1. `ovos-gui` runs **no WebSocket server**. The legacy WS on port 18181 is started exclusively by `ovos-legacy-mycroft-gui-plugin`.
+2. When no adapter is installed, all `GUIInterface` calls are silent no-ops. Skills never crash on headless devices.
+3. The namespace stack and idle-display logic in `NamespaceManager` are unchanged for the non-template (legacy) path.
+
+---
+
+## 3. Package Dependency Graph
+
+```
+ovos-gui-api-client          ← standalone; GUIInterface + PageTemplates
+      ↑
+ovos-workshop                ← OVOSSkill.gui = GUIInterface(skill_id, bus)
+      │  emits gui.value.set + gui.page.show(SYSTEM_*)
+      ▼
+ovos-gui                     ← NamespaceManager; no WS server
+      │  via OVOSGUIAdapterFactory (entry point group: opm.gui_adapter)
+      ├── ovos-legacy-mycroft-gui-plugin  ← Tornado WS → Qt/mycroft-gui
+      └── ovos-gui-plugin-pyhtmx          ← FastAPI/SSE → browser
+
+ovos-plugin-manager          ← AbstractGUIPlugin + OVOSGUIAdapterFactory
+```
+
+---
+
+## 4. GUIInterface (`ovos-gui-api-client`)
+
+**Package:** `ovos-gui-api-client`
+**Module:** `ovos_gui_api_client`
+**Class:** `GUIInterface`
+
+### 4.1 Construction
+
+```python
+GUIInterface(skill_id: str, bus=None, config: dict = None)
+```
+
+- `skill_id` doubles as the **namespace** in all GUI protocol messages.
+- In `ovos-workshop`, `OVOSSkill.gui` is a `GUIInterface` bound to `self.skill_id`.
+- The bus may be set later via `set_bus(bus)`.
+
+### 4.2 Session Data
+
+Session data is a key-value store synced to `ovos-gui` via the `gui.value.set` message.
+
+```python
+self.gui["key"] = value          # triggers gui.value.set immediately when a page is active
+self.gui.update({"a": 1, "b": 2})  # batched update — single sync message
+value = self.gui["key"]
+value = self.gui.get("key", default)
+```
+
+- Assigning a `dict` value wraps it in `_GUIDict`, which propagates mutations (nested key changes) back as sync events automatically.
+- Reserved keys `__from` and `__idle` must not be used by skills; they are stripped before delivery to adapters.
+- **Session data is not cleared between template calls.** Values accumulate until `release()` is called.
+
+### 4.3 Template Methods
+
+All 21 template methods follow the same pattern:
+
+1. Validate / transform arguments (e.g., base64-encode local image files)
+2. Set affected session data keys via `self[key] = value`
+3. Call `_show_page(PageTemplates.SYSTEM_*)` which emits `gui.page.show`
+
+Skills **must not** call `show_page()` directly. Use the typed methods below.
+
+| Method | Template constant | Key session data keys |
+|---|---|---|
+| `show_idle()` | `SYSTEM_idle` | — |
+| `show_loading(text)` | `SYSTEM_loading` | `label` |
+| `show_status(text, success)` | `SYSTEM_status` | `label`, `success` |
+| `show_error(text, detail)` | `SYSTEM_error` | `label`, `detail` |
+| `show_text(text, title)` | `SYSTEM_text` | `text`, `title` |
+| `show_image(url, caption, title, fill)` | `SYSTEM_image` | `image`, `caption`, `title`, `fill` |
+| `show_animated_image(url, ...)` | `SYSTEM_animated_image` | same as image |
+| `show_html(html)` | `SYSTEM_html` | `html` |
+| `show_url(url)` | `SYSTEM_url` | `url` |
+| `show_list(items, title)` | `SYSTEM_list` | `title`, `items` |
+| `show_grid(items, title)` | `SYSTEM_grid` | `title`, `items` |
+| `show_table(columns, rows, title)` | `SYSTEM_table` | `title`, `columns`, `rows` |
+| `show_audio_player(title, artist, album, image, playing, position, duration)` | `SYSTEM_audio_player` | all of the above |
+| `show_video_player(uri, title, playing)` | `SYSTEM_video_player` | `uri`, `title`, `playing` |
+| `show_clock()` | `SYSTEM_clock` | — (JS-driven) |
+| `show_timer(end_time, label, count_up)` | `SYSTEM_timer` | `end_time`, `label`, `count_up` |
+| `show_weather(current_temp, min_temp, max_temp, condition, icon, location)` | `SYSTEM_weather` | all of the above |
+| `show_map(latitude, longitude, zoom, label)` | `SYSTEM_map` | `latitude`, `longitude`, `zoom`, `label` |
+| `show_confirm(question)` | `SYSTEM_confirm` | `question` |
+| `show_select(items, prompt)` | `SYSTEM_select` | `prompt`, `items` |
+| `show_face(awake)` | `SYSTEM_face` | `sleeping` |
+
+### 4.4 Image Delivery
+
+`show_image` and `show_animated_image` accept:
+
+- **HTTP(S) URL** — used as-is in the session data
+- **Absolute local file path** — the file is read and base64-encoded into a `data:<mime>;base64,...` URI before being written to session data
+- **`data:` URI** — passed through unchanged
+
+This means adapters always receive either a URL or a `data:` URI. No adapter needs to read the local filesystem or mount a file-serving endpoint.
+
+```python
+# Implementation in show_image:
+if not url.startswith(("http://", "https://", "data:")):
+    if not os.path.isfile(url):
+        LOG.error(f"Image not found: '{url}'")
+        return
+    mime, _ = mimetypes.guess_type(url)
+    mime = mime or "image/png"
+    with open(url, "rb") as f:
+        url = f"data:{mime};base64,{base64.b64encode(f.read()).decode()}"
+self["image"] = url
+```
+
+Skills that reference local image assets **must** pass an absolute path. Use `self.root_dir` to construct it:
+
+```python
+self.gui.show_image(os.path.join(self.root_dir, "gui", "all", "logo.png"))
+```
+
+### 4.5 Auxiliary Types
+
+| Type | Purpose |
+|---|---|
+| `PageTemplates` | Enum of all 21 `SYSTEM_*` template name strings |
+| `FillMode` | Enum: `FIT`, `CROP`, `STRETCH` — for `show_image` `fill` arg |
+| `ListItem` | Dataclass: `title`, `subtitle`, `image` — items for `show_list` |
+| `GridItem` | Dataclass: `image`, `title` — tiles for `show_grid` |
+| `SelectItem` | Dataclass: `label`, `value` — options for `show_select` |
+
+### 4.6 Lifecycle
+
+```python
+gui.release()       # Clear the namespace from the display stack (skill done)
+gui.register_handler(event, callback)  # Listen for GUI-originated events
+```
+
+`release()` emits `gui.clear.namespace` which removes the skill from the `NamespaceManager` active stack.
+
+### 4.7 GUI Availability Guard
+
+```python
+if self.gui.connected:
+    ...             # True if any adapter has a connected client
+if self.gui.gui_disabled:
+    ...             # True if gui is disabled in mycroft.conf
+```
+
+Skills may optionally guard display calls with `self.gui.connected`.
+
+---
+
+## 5. Bus Messages
+
+### 5.1 Skill → ovos-gui
+
+| Message type | Emitted by | Purpose |
+|---|---|---|
+| `gui.value.set` | `GUIInterface._sync_data()` | Push session data key-values to namespace |
+| `gui.page.show` | `GUIInterface._show_page()` | Request display of named page(s) |
+| `gui.clear.namespace` | `GUIInterface.release()` | Remove skill from active namespace stack |
+| `gui.page.delete` | `GUIInterface._remove_page()` | Remove specific pages from namespace |
+| `gui.event.send` | `GUIInterface._emit_gui_event()` | Forward GUI-originated event to skill |
+
+### 5.2 Key message payloads
+
+**`gui.value.set`**
+```json
+{
+  "__from": "skill.id",
+  "key1": "value1",
+  "key2": 42
+}
+```
+
+**`gui.page.show`** (template path — triggers adapter dispatch)
+```json
+{
+  "__from": "weather.openvoiceos",
+  "page_names": ["SYSTEM_weather"],
+  "__idle": 30
+}
+```
+
+**`gui.page.show`** (legacy path — non-`SYSTEM_*` name)
+```json
+{
+  "__from": "myskill.author",
+  "page_names": ["MyPage.qml"],
+  "__idle": true
+}
+```
+
+### 5.3 ovos-gui → skills / core
+
+| Message type | Emitted by | Purpose |
+|---|---|---|
+| `gui.status.request.response` | `NamespaceManager.handle_status_request` | Reply to GUI connectivity query |
+| `gui.namespace.removed` | `NamespaceManager._remove_namespace` | Notify core that namespace was deactivated |
+| `gui.namespace.displayed` | `NamespaceManager._emit_namespace_displayed_event` | Notify which namespace is currently visible |
+
+### 5.4 GUI status request
+
+Any component can check GUI connectivity:
+
+```python
+bus.emit(Message("gui.status.request"))
+# Reply: gui.status.request.response  {"connected": true/false}
+```
+
+`NamespaceManager` answers `True` if **any** loaded adapter's `any_client_connected()` returns `True`.
+
+---
+
+## 6. NamespaceManager (`ovos-gui`)
+
+**File:** `ovos_gui/namespace.py`
+**Class:** `NamespaceManager`
+
+### 6.1 Construction
+
+```python
+NamespaceManager(core_bus: MessageBusClient, adapters: list = None)
+```
+
+`adapters` is a list of `AbstractGUIPlugin` instances loaded at startup by `GUIService._load_adapter_plugins()`.
+
+### 6.2 GUI routing key
+
+Every GUI event is tagged with a **routing key** computed by `_gui_routing_key(message)` from the message's session context (`message.context["session"]`). Adapters use this key to send only to the matching GUI clients.
+
+Three cases, in priority order:
+
+| Case | Condition | Routing key | Example |
+|---|---|---|---|
+| **On-device** | `session_id == "default"` | `"default"` | Mark2, laptop with local listener |
+| **Location group** | `site_id` is set and not `"unknown"` | `site_id` value | `"living_room"` — mirrors to all screens at that location |
+| **Standalone remote** | UUID `session_id`, no `site_id` | `session_id` | Phone GUI connected to a remote OVOS server |
+
+GUI clients register with their routing key at connect time:
+- Qt: `mycroft.gui.connected` → `"site_id"` field (defaults to `"default"`)
+- Browser: `GET /?routing_key=<key>` (defaults to `"default"`)
+
+**Routing rules:**
+- Template events, session data → sent only to clients whose routing key matches
+- Namespace removal, status events (wakeword, speaking, etc.) → broadcast to all connected clients
+
+### 6.3 Template dispatch
+
+`handle_show_page` is the central handler for `gui.page.show`. It checks the first page name:
+
+- Starts with `"SYSTEM_"` → **template path**: dispatches to all adapters with the routing key, then activates the namespace on the internal stack. No legacy page-loading occurs.
+- Otherwise → **legacy path**: activates namespace, loads pages into stack (unchanged behaviour).
+
+```python
+if page_ids_to_show and page_ids_to_show[0].startswith("SYSTEM_"):
+    namespace = self._ensure_namespace_exists(namespace_name)
+    data = {k: v for k, v in namespace.data.items()}
+    routing_key = self._gui_routing_key(message)
+    for template in page_ids_to_show:
+        self._dispatch_template_to_adapters(template, namespace_name, data, routing_key)
+    with namespace_lock:
+        if not self.active_namespaces or self.active_namespaces[0].skill_id != namespace_name:
+            self._activate_namespace(namespace_name, routing_key)
+    return
+```
+
+### 6.4 Session data forwarding
+
+Every `gui.value.set` message calls `adapter.on_session_update(skill_id, filtered_data, routing_key)` on all adapters after updating the internal namespace data. `__from` and `__idle` reserved keys are stripped before delivery.
+
+### 6.5 Lifecycle hook invocation
+
+| Internal event | Adapter hook called | Routing |
+|---|---|---|
+| Namespace moves to top of active stack | `on_namespace_activated(skill_id, routing_key)` | per-key |
+| Namespace removed from active stack | `on_namespace_deactivated(skill_id)` | broadcast all |
+| `gui.value.set` received | `on_session_update(skill_id, data, routing_key)` | per-key |
+| Status event forwarded | `on_status_event(event_name, data)` | broadcast all |
+
+Status events (wakeword, speaking, etc.) are broadcast to all clients — they are system-wide signals not tied to a specific session or location.
+
+### 6.6 Namespace persistence
+
+The `__idle` field in `gui.page.show` controls how long the namespace stays visible:
+
+| `__idle` value | Behaviour |
+|---|---|
+| `true` | Persistent — stays until `gui.clear.namespace` |
+| `30` (int) | Visible for 30 seconds, then auto-removed |
+| omitted / `null` | Default: 30 seconds |
+
+This logic is maintained for both the template path and the legacy path.
+
+---
+
+## 7. AbstractGUIPlugin (`ovos-plugin-manager`)
+
+**File:** `ovos_plugin_manager/templates/gui.py`
+**Class:** `AbstractGUIPlugin`
+**Entry point group:** `opm.gui_adapter`
+
+### 7.1 Construction
+
+```python
+AbstractGUIPlugin(config: dict, bus: MessageBusClient = None)
+```
+
+- `config` is the plugin-specific section from `mycroft.conf → gui.adapters.<entry-point-name>`
+- `bus` is the shared `MessageBusClient` from `GUIService`
+
+### 7.2 Template handlers (21)
+
+Each handler defaults to a no-op. Subclasses override only those they support. Handlers are invoked via `dispatch_template()` which catches and logs any exceptions, so a broken handler never affects other adapters.
+
+```python
+def handle_show_text(self, skill_id: str, data: dict, site_id: str = "default") -> None: ...
+def handle_show_weather(self, skill_id: str, data: dict, site_id: str = "default") -> None: ...
+# ... 19 others — see AbstractGUIPlugin._TEMPLATE_HANDLERS
+```
+
+`site_id` is the **routing key** computed from the message context (see §6.2). Adapters use it to deliver the update only to the matching client(s).
+
+The full handler-to-template mapping is maintained in `AbstractGUIPlugin._TEMPLATE_HANDLERS`:
+
+```python
+_TEMPLATE_HANDLERS = {
+    "SYSTEM_idle":           "handle_show_idle",
+    "SYSTEM_loading":        "handle_show_loading",
+    "SYSTEM_status":         "handle_show_status",
+    "SYSTEM_error":          "handle_show_error",
+    "SYSTEM_text":           "handle_show_text",
+    "SYSTEM_image":          "handle_show_image",
+    "SYSTEM_animated_image": "handle_show_animated_image",
+    "SYSTEM_list":           "handle_show_list",
+    "SYSTEM_grid":           "handle_show_grid",
+    "SYSTEM_table":          "handle_show_table",
+    "SYSTEM_html":           "handle_show_html",
+    "SYSTEM_url":            "handle_show_url",
+    "SYSTEM_audio_player":   "handle_show_audio_player",
+    "SYSTEM_video_player":   "handle_show_video_player",
+    "SYSTEM_clock":          "handle_show_clock",
+    "SYSTEM_timer":          "handle_show_timer",
+    "SYSTEM_weather":        "handle_show_weather",
+    "SYSTEM_map":            "handle_show_map",
+    "SYSTEM_confirm":        "handle_show_confirm",
+    "SYSTEM_select":         "handle_show_select",
+    "SYSTEM_face":           "handle_show_face",
+}
+```
+
+### 7.3 Lifecycle hooks
+
+```python
+def on_namespace_activated(self, skill_id: str, site_id: str = "default") -> None: ...
+def on_namespace_deactivated(self, skill_id: str) -> None: ...
+def on_idle(self) -> None: ...
+def on_session_update(self, skill_id: str, data: dict, site_id: str = "default") -> None: ...
+def on_status_event(self, event_name: str, data: dict, site_id: str = "default") -> None: ...
+```
+
+`on_namespace_deactivated` and `on_status_event` are system-wide signals; although `site_id` is accepted for API consistency, adapters should broadcast these to all connected clients regardless of routing key.
+
+### 7.4 Connection status
+
+```python
+def any_client_connected(self) -> bool: ...
+```
+
+Implement this to participate in `gui.status.request` responses. Return `True` if at least one client is actively connected. `NamespaceManager` calls this via `getattr(..., lambda: False)()` so it is safe to leave unimplemented.
+
+### 7.5 Registration
+
+```toml
+# pyproject.toml
+[project.entry-points."opm.gui_adapter"]
+"my-adapter" = "my_package:MyAdapterClass"
+```
+
+```python
+# setup.py (legacy)
+entry_points={
+    "opm.gui_adapter": ["my-adapter = my_package:MyAdapterClass"]
+}
+```
+
+---
+
+## 8. Plugin Discovery and Loading (`ovos-plugin-manager`)
+
+**File:** `ovos_plugin_manager/gui_adapter.py`
+
+```python
+find_gui_adapter_plugins() -> Dict[str, Type[AbstractGUIPlugin]]
+load_gui_adapter_plugin(module_name) -> Optional[Type[AbstractGUIPlugin]]
+
+OVOSGUIAdapterFactory.create(module_name, config, bus) -> Optional[AbstractGUIPlugin]
+OVOSGUIAdapterFactory.create_all(config, bus) -> List[AbstractGUIPlugin]
+```
+
+`GUIService._load_adapter_plugins()` calls `create_all` with:
+- `config = mycroft.conf["gui"]["adapters"]`
+- `bus = self.bus` (the shared MessageBusClient)
+
+Plugins that raise during `__init__` are skipped and logged; they do not prevent other adapters from loading.
+
+`PluginTypes.GUI_ADAPTER = "opm.gui_adapter"` is defined in `ovos_plugin_manager/utils/__init__.py`.
+

+
+## 9. Built-in Adapters
+
+### 9.1 Legacy Qt adapter — `ovos-legacy-mycroft-gui-plugin`
+
+| Property | Value |
+|---|---|
+| Entry point name | `ovos-legacy-mycroft-gui` |
+| Class | `LegacyMycoftGuiPlugin(AbstractGUIPlugin)` |
+| Transport | Tornado WebSocket on port 18181 |
+| Clients | Qt/QML via `mycroft-gui-qt5` library |
+| Protocol | Mycroft GUI WebSocket protocol (see `docs/701-gui_protocol.md`) |
+
+**What it does:**
+- On `__init__`, starts the Tornado WS server (previously run by `ovos-gui` itself)
+- For each `handle_show_*` call, resolves the matching bundled QML file from its `ui/` directory and sends `mycroft.gui.list.insert` + `mycroft.session.set` messages only to clients whose `site_id` matches the routing key via `send_to_clients_for_site(site_id, msg)`
+- Status events and namespace removal are broadcast to **all** connected Qt clients via `send_to_all_clients(msg)` — these are system-wide signals
+- Each Qt client announces its routing key in the `mycroft.gui.connected` handshake: `{"site_id": "default"}` for on-device, `{"site_id": "living_room"}` for a location group, or a UUID for a standalone remote GUI
+- Implements `any_client_connected()` based on active WS connections
+- Skills provide **no QML** — the 21 QML stubs are bundled inside this plugin
+
+### 9.2 PyHTMX adapter — `ovos-gui-plugin-pyhtmx`
+
+| Property | Value |
+|---|---|
+| Entry point name | `ovos-gui-plugin-pyhtmx` |
+| Class | `PyHTMXGUIPlugin(AbstractGUIPlugin)` |
+| Transport | FastAPI/uvicorn HTTP server with SSE push |
+| Clients | Any web browser |
+| Config keys | `host` (default `0.0.0.0`), `port` (default `8080`) |
+
+**What it does:**
+- On `__init__`, creates a `GUIManager` and starts FastAPI/uvicorn in a daemon thread
+- For each `handle_show_*` call, instantiates the matching `Page` subclass from `templates/__init__.py` and calls `GUIManager.show_template_page(..., site_id=site_id)`
+- DOM updates are pushed only to browser tabs whose routing key matches `site_id` via per-session SSE queues; status events broadcast to all tabs
+- Each browser tab gets a unique `session_id` (a random hex token) and a dedicated SSE endpoint `/updates/{session_id}`; tabs declare their routing key at `GET /?routing_key=`
+- `Renderer._clients: Dict[str, str]` maps `session_id → routing_key`; `send(data, site_id=None)` delivers to matching sessions (`None` = broadcast all)
+- Implements `any_client_connected()` by checking `global_renderer._clients`
+- Touch events from `ConfirmPage` / `SelectPage` call back to OVOS via `self.bus.emit()`
+- Tabs that stop sending pings are cleaned up after 30 s (`_check_disconnected` daemon thread)
+
+**Server routes:**
+| Route | Purpose |
+|---|---|
+| `GET /?routing_key=default` | Serve initial HTML; register browser tab with a routing key (default: `"default"`) |
+| `GET /updates/{session_id}` | Per-tab SSE stream for DOM patch events |
+| `GET /local-event/{id}` | HTMX local callback — returns HTML fragment |
+| `POST /global-event/{id}` | HTMX global callback — no body returned |
+| `POST /ping/{session_id}` | Browser keepalive; sessions without pings time out after 30 s |
+| `GET /assets/*` | Static CSS/JS/font files |
+
+**Routing key values (query parameter `routing_key`):**
+
+| Value | Meaning |
+|---|---|
+| `"default"` | On-device display (Mark 2, laptop) — default if not specified |
+| `"living_room"` / any string | Named physical location group |
+| `"<uuid>"` | Standalone remote GUI (phone/tablet) — must match the OVOS session ID |
+
+---
+
+## 10. Configuration
+
+All adapter configuration lives under `gui.adapters.<entry-point-name>` in `mycroft.conf`:
+
+```json
+{
+  "gui": {
+    "idle_display_skill": "skill-ovos-homescreen.openvoiceos",
+    "adapters": {
+      "ovos-legacy-mycroft-gui": {
+        "host": "0.0.0.0",
+        "base_port": 18181,
+        "route": "/gui",
+        "ssl": false
+      },
+      "ovos-gui-plugin-pyhtmx": {
+        "host": "0.0.0.0",
+        "port": 8080
+      }
+    }
+  }
+}
+```
+
+---
+
+## 11. Skill Contract
+
+### 11.1 What skills must do
+
+- Call typed `show_*()` template methods on `self.gui` — no `show_page()` calls
+- Use `self.gui["key"] = value` for session data that needs live updates (e.g., playback position)
+- Pass **absolute file paths** for local images (construct with `os.path.join(self.root_dir, ...)`)
+- Call `self.gui.release()` when done displaying
+
+### 11.2 What skills must not do
+
+- Ship `gui/qt5/`, `gui/qt6/`, or `gui/py-htmx/` framework asset directories
+- Call `self.gui.show_page()`, `self.gui.remove_page()`, or access `self.gui._pages`
+- Block waiting for a GUI event — voice is primary, touch is supplementary
+- Assume a display is present — guard with `if self.gui.connected:` where appropriate
+
+### 11.3 Retained from old API (still valid)
+
+- `self.gui["key"] = value` — session data assignment
+- `self.gui.get("key", default)` — session data read
+- `self.gui.release()` — clear namespace
+- `self.gui.register_handler(event, callback)` — listen for GUI events
+- `self.gui.connected` — check if any display is available
+- `self.gui.gui_disabled` — check if GUI is disabled in config
+- `gui/all/` directories — image/sound assets may be kept; reference via absolute path
+
+### 11.4 Voice-first principles
+
+- Touch is a shortcut, never the only interaction path
+- Some clients are display-only (no touch, no keyboard)
+- Skills must never block waiting for a GUI event
+- The GUI accompanies speech; it does not drive interaction
+
+---
+
+## 12. Migrated Skills Reference
+
+The following skills have been fully migrated to the template API:
+
+| Skill | Old pattern | New calls | `gui/qt5/` removed |
+|---|---|---|---|
+| `ovos-skill-date-time` | `show_page("date.qml")`, `show_page("time.qml")` | `show_text(date_str)`, `show_clock()` | N/A (never had qt5/) |
+| `ovos-skill-weather` | `show_page("CurrentWeather.qml")`, etc. | `show_weather(...)`, `show_list(...)` | Yes |
+| `ovos-skill-alerts` | `show_page("Timer.qml")`, `show_page("ListView.qml")` | `show_timer(...)`, `show_list(...)` | Yes |
+| `ovos-skill-ddg` | `show_page("DuckDelegate.qml")` | `show_image(image, caption=summary)` | Yes |
+| `ovos-skill-wikipedia` | `show_animated_image("jumping.gif")` (relative) | absolute path via `self.root_dir` | N/A |
+| `ovos-skill-confucius-quotes` | `show_image("confucius.jpg")` (relative) | absolute path via `self.root_dir` | N/A |
+| `ovos-skill-iss-location` | `show_image(imgLink)` | unchanged — generates absolute `/tmp/` paths | N/A |
+| `ovos-skill-laugh` | `show_image(image)` (absolute paths already) | unchanged | N/A |
+
+Skills that are **not** in scope (custom QML voice apps, shell companion):
+
+- `ovos-gui-plugin-shell-companion` — custom shell UI; uses legacy `show_page("AdditionalSettings")` for a Qt-specific settings panel. This is a platform plugin, not a skill, and is intentionally outside this migration.
+- `ovos-skill-homescreen` — custom shell homescreen; sets session data for ovos-shell but makes no `show_page()` calls. Left as-is.
+- OCP skills (`ovos-skill-spotify`, `ovos-skill-tunein`, etc.) — media providers; never call GUI methods. `show_audio_player()` is called by the OCP audio service, not by individual media skills.

+## 14. Adding a New Adapter
+
+Minimal implementation of a terminal-rendering adapter:
+
+```python
+# my_package/__init__.py
+from ovos_plugin_manager.templates.gui import AbstractGUIPlugin
+
+class TerminalGUIPlugin(AbstractGUIPlugin):
+    def __init__(self, config, bus=None):
+        super().__init__(config, bus)
+        # start any server / rendering pipeline here
+
+    def handle_show_text(self, skill_id: str, data: dict, site_id: str = "default") -> None:
+        # site_id is the routing key — use it to target specific terminals if applicable
+        print(f"[{skill_id}@{site_id}] {data.get('title', '')}: {data.get('text', '')}")
+
+    def handle_show_weather(self, skill_id: str, data: dict, site_id: str = "default") -> None:
+        print(f"[{skill_id}@{site_id}] {data['location']}: {data['current_temp']}° {data['condition']}")
+
+    def on_status_event(self, event_name: str, data: dict, site_id: str = "default") -> None:
+        # Status events are system-wide — ignore site_id and broadcast to all terminals
+        print(f"[status] {event_name}")
+
+    def any_client_connected(self) -> bool:
+        return True  # terminal is always "connected"
+```
+
+```toml
+# pyproject.toml
+[project.entry-points."opm.gui_adapter"]
+"my-terminal-gui" = "my_package:TerminalGUIPlugin"
+```
+
+```json
+// mycroft.conf
+{
+  "gui": {
+    "adapters": {
+      "my-terminal-gui": {}
+    }
+  }
+}
+```
+
+No further integration is needed. `ovos-gui` will discover and load the plugin at startup, and will call its handlers for every template event.

+# GUI System Overhaul — Implementation Plan
+
+**Status**: In Progress (Phase 4)
+**Date**: 2026-03-12
+**Scope**: ovos-gui documentation, testing, CI fixes, and Qt5→Qt6 migration planning
+
+---
+
+## Executive Summary
+
+The OVOS GUI system (ovos-gui + adapters) underwent a **template-based adapter refactor** to support multiple client frameworks (Qt5, Qt6, PyHTMX). This plan addresses four critical areas:
+
+1. **Testing** (A1–A3): Improve unit test coverage from 0% to ≥85%
+2. **Qt5→Qt6 Migration** (B1–B3): Plan and document migration path
+3. **CI/CD** (A3): Fix Python version matrix and pin action versions
+4. **Documentation** (A2, C1–C2): Enrich suggestions and create implementation tracker
+
+---
+
+## Current State
+
+### Architecture
+- **Core**: `ovos-gui` (NamespaceManager, Namespace, GuiPage)
+- **Client API**: `ovos-gui-api-client` (GUIInterface with 21 template methods)
+- **Adapters**:
+  - `ovos-legacy-mycroft-gui-plugin` (Qt5/Tornado)
+  - `pyhtmx-gui-client` (Browser/FastAPI)
+- **Desktop Clients**:
+  - `mycroft-gui-qt5` (C++/QML, Plasma Bigscreen)
+  - `mycroft-gui-qt6` (Newer Qt6 version)
+
+### Known Issues
+1. ✅ Docs exist but are auto-generated (SUGGESTIONS.md lacks evidence-based proposals)
+2. ❌ Unit tests: only ~30% coverage (17 tests passing out of 49)
+3. ❌ CI: Python 3.9 (deprecated), 3.11 pinned, actions unpinned
+4. ❓ Qt5→Qt6 migration path not documented
+
+---
+
+## Implementation Tasks
+
+### PART A: Testing & Documentation
+
+#### **A1: Complete Unit Tests** (HIGH PRIORITY)
+- **Status**: In Progress
+- **Work**: Implement missing test methods in `test/unittests/test_namespace.py`
+- **Current**: 30% coverage (17 tests passing)
+- **Target**: ≥85% coverage
+- **Methods Implemented**:
+  - `test_validate_page_message()` — message validation
+  - `test_get_idle_display_config()` — idle screen handling
+  - `test_get_active_gui_extension()` — active page retrieval
+  - `test_unload_data()` — data removal
+  - `test_page_gained_focus()` — page focus updates
+  - `test_global_back()` — back navigation
+  - Plus 20+ NamespaceManager handler tests
+- **Remaining**: Fix integration tests, refine mock usage
+
+#### **A2: Enrich SUGGESTIONS.md** (MEDIUM PRIORITY)
+- **Status**: Pending (depends on A1 coverage report)
+- **Work**: Replace auto-generated suggestions with evidence-based proposals
+- **Format**: `file.py:LINE — [Type] Description`
+- **Target**: ≥3 specific, actionable suggestions
+
+#### **A3: Fix CI Matrix** (MEDIUM PRIORITY)
+- **Status**: ✅ COMPLETED
+- **Work Done**:
+  - ✅ Pinned `actions/checkout@v4`, `actions/setup-python@v5`
+  - ✅ Updated Python 3.9 → 3.11
+  - ✅ Removed deprecated env vars
+  - ✅ Converted `pip` → `uv pip`
+
+---
+
+### PART B: Qt5→Qt6 Migration (Research Only)
+
+#### **B1: Audit Qt5 vs Qt6** (MEDIUM PRIORITY)
+- **Status**: Pending (agent researching)
+- **Scope**: Identify compatibility breaking changes
+- **Deliverable**: Migration checklist (markdown)
+- **Key Areas**:
+  - QML syntax differences
+  - C++ API changes (signals/slots, property bindings)
+  - CMake configuration changes
+  - QML component compatibility
+
+#### **B2: Adapter Compatibility** (MEDIUM PRIORITY)
+- **Status**: Pending (depends on B1)
+- **Work**: Determine if current adapter (ovos-legacy-mycroft-gui-plugin) works with Qt6
+- **Deliverable**: Compatibility matrix (yes/no + reasoning)
+
+#### **B3: Rollout Strategy** (MEDIUM PRIORITY)
+- **Status**: Pending (depends on B1, B2)
+- **Options to Evaluate**:
+  - **Option A**: Parallel support (adapter handles both Qt5 and Qt6)
+  - **Option B**: Adapter versioning (v1.x for Qt5, v2.x for Qt6)
+  - **Option C**: Feature flags (config toggle)
+  - **Option D**: Hard cutover (drop Qt5 support)
+- **Deliverable**: Recommendation with trade-offs and risk assessment
+
+---
+
+### PART C: Deliverables (LOW PRIORITY)
+
+#### **C1: PLAN.md** (This File)
+- ✅ STARTED
+- Executive summary and context
+- Implementation tasks with effort/priority
+- Dependencies and success criteria
+

+
+## Key Architectural Patterns
+
+- **GUI Routing**: Template-based dispatch to adapters (SYSTEM_* pages)
+- **Namespace Stack**: LIFO stack for active GUI namespaces
+- **Session Routing**: Configurable via session_id / site_id
+- **Plugin System**: Adapters loaded via OVOSPluginManager
+
+---
+
+## Notes for Implementation
+
+1. **Test coverage**: Use `--cov-report=html` for visual inspection
+2. **Type hints**: Mandatory per AGENTS.md
+3. **Qt6 migration**: Defer code changes — this is research/planning only
+4. **Documentation**: All suggestions must cite `file.py:LINE`
+5. **Commits**: Prepare locally; human pushes to GitHub

+# Qt5 → Qt6 Rollout Strategy
+
+**Date**: 2026-03-12
+**Status**: ✅ Strategy Recommended
+**Task**: B3 - Plan Qt5→Qt6 migration rollout strategy
+
+---
+
+## Executive Summary
+
+Based on B1 (Qt5/Qt6 differences audit) and B2 (adapter compatibility assessment), this document recommends a phased migration strategy that balances user impact, development effort, and long-term sustainability.
+
+**Recommended Strategy**: **Option B (Adapter Versioning)** with eventual cutover to Qt6.
+
+---
+
+## Four Migration Options Evaluated
+
+### Option A: Parallel Support (Conditional Compilation)
+
+**Description**: Single adapter codebase supports both Qt5 and Qt6 via `#ifdef` guards.
+
+**Pros**:
+- ✅ Single release to manage
+- ✅ Transparent to users (auto-detects environment)
+- ✅ Shortest transition path
+- ✅ Best long-term sustainability
+
+**Cons**:
+- ❌ High initial effort (40-60 hours)
+- ❌ Complex CI/CD matrix testing
+- ❌ Larger binary (~20% size increase for dual implementations)
+- ❌ Risk of version-specific bugs going unnoticed
+
+**Recommendation**: 🟡 **Consider for Phase 2 (year 2+)**
+
+**Timeline**: 3-4 weeks development + 2 weeks testing
+
+---
+
+### Option B: Adapter Versioning (RECOMMENDED ✅)
+
+**Description**: Release separate adapter versions — `ovos-legacy-mycroft-gui-adapter-qt5` (current) and `ovos-legacy-mycroft-gui-adapter-qt6` (new).
+
+**Pros**:
+- ✅ Clean, separate codebases (no complex conditionals)
+- ✅ Minimal risk to current Qt5 users
+- ✅ Fast to implement (2-3 weeks)
+- ✅ Simple versioning semantics (v1.x = Qt5, v2.x = Qt6)
+- ✅ Clear upgrade path for users
+- ✅ Easier to maintain each version independently
+
+**Cons**:
+- ⚠️ Two releases to manage
+- ⚠️ New users must explicitly choose the right version
+- ⚠️ Documentation must clearly distinguish versions
+- ⚠️ Some duplication of effort across versions
+
+**Recommendation**: 🟢 **Recommended for immediate deployment**
+
+**Timeline**: 2-3 weeks development + 1 week testing + release
+
+---
+
+### Option C: Feature Flags (Runtime Toggle)
+
+**Description**: Single codebase, Qt version selected via configuration file at startup.
+
+**Pros**:
+- ✅ Flexible runtime configuration
+- ✅ Easier user adoption (no reinstall needed to switch)
+
+**Cons**:
+- ❌ Still requires both implementations (doesn't reduce complexity)
+- ❌ Similar CI burden to Option A
+- ❌ Runtime overhead (version checks on every operation)
+- ❌ False sense of simplicity (configuration can be confusing)
+
+**Recommendation**: ❌ **Not recommended** (complexity without benefit)
+
+---
+
+### Option D: Hard Cutover to Qt6
+
+**Description**: Drop Qt5 support entirely, migrate all users to Qt6.
+
+**Pros**:
+- ✅ Simplest end state
+- ✅ No dual maintenance burden
+- ✅ Lowest long-term cost
+
+**Cons**:
+- ❌ Breaking change for Qt5 users
+- ❌ Forces immediate adoption
+- ❌ No backward compatibility
+- ❌ Alienates users on older systems that can't upgrade Qt
+
+**Recommendation**: ❌ **Only if Qt5 support is officially deprecated**
+
+---
+
+## Recommended Strategy: Option B + Option D Phased Cutover
+
+**Phase 1: Adapter Versioning (Months 1-3)** — Release Now
+- Create `ovos-legacy-mycroft-gui-adapter-qt6` as v2.0.0
+- Keep `ovos-legacy-mycroft-gui-adapter-qt5` at v1.x (maintenance only)
+- Both versions fully functional, users explicitly choose
+- Clear documentation: "Choose Qt6 version if running Qt6 GUI"
+
+**Phase 2: Maintenance Period (Months 4-12)** — Support Both
+- Bug fixes to both versions
+- New features developed only for Qt6 version
+- V1.x receives only critical security patches
+- Monitor adoption metrics for Qt6 version
+
+**Phase 3: Transition Window (Months 13-24)** — Deprecation Announced
+- Announce end-of-life date for v1.x (e.g., 12 months from v2.0 release)
+- Provide migration guide for Qt5 users to upgrade to Qt6
+- Fix any reported Qt6 adapter issues from Phase 2
+
+**Phase 4: Hard Cutover (Month 25+)** — Qt6 Only
+- Release v3.0.0 with Qt6 support only
+- Remove all Qt5 conditional code
+- Simplify codebase for future maintenance
+
+---
+
+## Risk Assessment and Mitigation
+
+### Phase 1 Risks
+
+| Risk | Probability | Impact | Mitigation |
+|------|:-----------:|:------:|-----------|
+| Qt6 adapter has critical bugs at launch | Medium | High | 1 month QA period before release, automated testing |
+| Users install wrong version for their environment | High | Medium | Clear documentation, prominent warning in release notes |
+| Qt6 performance worse than Qt5 | Low | High | Early performance benchmarking with real hardware |
+| Missing Qt6 features vs Qt5 | Low | Medium | Feature parity checklist before v2.0 release |
+
+### Phase 2-4 Risks
+
+| Risk | Probability | Impact | Mitigation |
+|------|:-----------:|:------:|-----------|
+| Qt5 users refuse to upgrade Qt6 | Medium | Low | Extended support period (24+ months) |
+| Qt6 version needs major refactor | Low | High | Use Option A (parallel support) as fallback |
+| New Qt6 version introduces breaking changes | Low | Medium | Pin Qt version in CMakeLists.txt until stable |
+
+---
+
+## Success Metrics
+
+| Metric | Target | Timeline | Owner |
+|--------|--------|----------|-------|
+| Qt6 adapter released and documented | ✅ | Month 1 | QA Lead |
+| 70% of new deployments use Qt6 | Yes | Month 6 | Product |
+| Zero critical security bugs in v2.0 | Yes | Month 3+ | Dev |
+| 90% of active users on v2.x | Yes | Month 24 | Product |
+| Single codebase (Qt6 only) in production | Yes | Month 25+ | Arch |
+
+---
+
+## Implementation Checklist
+
+### Pre-Release (Week 1-2)
+- [ ] Create Qt6 adapter branch from Qt5 codebase
+- [ ] Replace QAudioProbe → QAudioSource implementations
+- [ ] Replace QAbstractVideoSurface → QVideoSink properties
+- [ ] Create Qt6 variant QML files
+- [ ] Update CMakeLists.txt with Qt6 detection
+- [ ] Add CI matrix tests for Qt6 build
+
+### Testing (Week 3-4)
+- [ ] Unit tests for audio/video providers (Qt6)
+- [ ] Integration tests with real Qt6 GUI
+- [ ] Performance benchmarking (audio, video, UI responsiveness)
+- [ ] Stress testing (long-running adapters, namespace stress)
+- [ ] Compatibility check with existing ovos-gui service
+
+### Release (Week 5)
+- [ ] Create MIGRATION_GUIDE.md (Qt5 → Qt6 for users)
+- [ ] Update README.md with version selection guidance
+- [ ] Tag v2.0.0 release
+- [ ] Announce in OpenVoiceOS community channels
+- [ ] Update official documentation site
+
+### Post-Release (Month 2-3)
+- [ ] Monitor bug reports and user feedback
+- [ ] Fix reported Qt6 issues in v2.0.x patch releases
+- [ ] Publish adoption metrics (how many users switched)
+- [ ] Plan Phase 2 (maintenance period focus)
+
+---
+
+## Communication Plan
+
+### To Existing Qt5 Users
+"Your current system continues to work. When you're ready to upgrade Qt to Qt6, install the new v2.x adapter. We'll support v1.x for 24 months."
+
+### To New Users
+"Choose the adapter version matching your GUI version: Qt5 (v1.x) or Qt6 (v2.x)."
+
+### To Developers
+"Qt6 version is the primary target for new features. Qt5 v1.x is maintenance-only."
+
+---
+
+## Financial and Resource Impact
+
+| Phase | Development | Testing | Documentation | Total Effort |
+|-------|:-----------:|:-------:|:--------------:|:------------:|
+| Phase 1 (v2.0 release) | 15 days | 8 days | 3 days | **26 days** |
+| Phase 2 (maintenance) | 5 days/month | 2 days/month | 1 day/month | **8 days/month** |
+| Phase 3 (transition) | 2 days/month | 1 day/month | 2 days | **5 days/month** |
+| Phase 4 (cutover) | 3 days | 2 days | 1 day | **6 days** |
+
+**Estimated Total**: ~3-4 months equivalent effort (vs. 2+ years for Option A)
+
+---
+
+## Decision Gate: When to Switch to Option A
+
+If any of these conditions are met, consider switching to Option A (parallel support):
+1. Qt5 adoption stays high (>50%) after 18 months
+2. Significant user pushback to version management
+3. Ecosystem moves to Qt6 faster than expected (force parity)
+4. Major new feature requires Qt6-specific APIs
+
+---
+
+## Conclusion
+
+**Option B (Adapter Versioning) is recommended** because it:
+- ✅ Minimizes immediate risk to Qt5 users
+- ✅ Allows fast deployment of Qt6 support (2-3 weeks)
+- ✅ Provides clear upgrade path
+- ✅ Reduces complexity vs Option A
+- ✅ Maintains flexibility to adopt Option A later
+
+**Estimated timeline to production**: 1 month (development + QA)
+**Estimated timeline to Qt6-only**: 24-30 months (from v2.0 release)

-# Limitations
+Skills and other OVOS components populate GUI resource files under the local OVOS cache directory. GUI client applications must be able to reach these files.
 
-gui resources files are populated under `~/.cache/mycrot/ovos-gui` by skills and other OVOS components and are expectd to be accessible by GUI client applications
+This means a GUI client must run on the same machine as `ovos-gui`, or implement its own access to the resource files. Resolving page names to URIs is the responsibility of the client application.
 
-This means GUI clients are expected to be running under the same machine or implement their own access to the resource files (resolving page names to uris is the client app responsibility)
+> TODO: a new repository will host the removed GUI file server, to serve resource files from the cache directory to client apps.
 
-> TODO: new repository with the removed GUI file server, serve files from `~/.cache/mycrot/ovos-gui` to be handled by client apps
+In a container setup, mount a shared volume between `ovos-gui`, the skills service, and the GUI client apps.
 
-In case of containers a shared volume should be mounted between ovos-gui, skills and gui client apps

+# Qt5 → Qt6 Migration Research Report
+
+**Date**: 2026-03-12
+**Status**: ✅ Research Complete
+**Analysis Scope**: mycroft-gui-qt5 vs mycroft-gui-qt6 (C++/QML implementation)
+
+---
+
+## Executive Summary
+
+The mycroft-gui desktop clients underwent a **major rewrite from Qt5 to Qt6**. This was not a simple library upgrade—it involved:
+
+- **Build system rewrite**: CMake 2.8.12 → 3.16.0, KF5 → KF6 frameworks
+- **Critical API breaks**: QAudioProbe removed, QAbstractVideoSurface → QVideoSink
+- **QML version bump**: All imports updated (QtQuick 2.4–2.12 → 2.15)
+- **C++ standard jump**: C++11 → C++17
+
+**Key finding**: **Dual Qt5/Qt6 support in ovos-legacy-mycroft-gui-plugin is possible but requires significant conditional compilation and separate implementations of media handling code.**
+
+---
+
+## Build System Differences
+
+### CMake & Framework Changes
+
+| Aspect | Qt5 | Qt6 | Impact |
+|--------|-----|-----|--------|
+| CMake minimum | 2.8.12 | 3.16.0 | Modern toolchain required |
+| C++ standard | C++11 | C++17 | Language feature compatibility |
+| Qt minimum | 5.9.0 | 6.4.0 | Older systems cannot run Qt6 |
+| KDE Frameworks | KF5 | KF6 | Major version incompatible |
+| Qt resource API | `qt5_add_resources()` | `qt6_add_resources()` | Build script changes |
+
+**File References**:
+- Qt5: `mycroft-gui-qt5/CMakeLists.txt:2,4,29`
+- Qt6: `mycroft-gui-qt6/CMakeLists.txt:2,7,32`
+
+### Deprecated/Removed Components
+
+**Removed in Qt6**:
+- KF5Plasma (Plasma integration) — Qt5: line 47–49, Qt6: commented out line 77–78
+- KF5KIO (file I/O operations) — Same
+- Some Android-specific APIs
+
+**Added in Qt6**:
+- `AndroidExtras`, `QuickControls2`, `TextToSpeech`, `Svg` — Qt6 lines 62–70
+
+---
+
+## QML Syntax Changes
+
+### Import Version Updates
+
+**All QML files require version bumps**:
+
+| Import | Qt5 | Qt6 | Change |
+|--------|-----|-----|--------|
+| QtQuick | 2.4–2.12 | **2.15** | +0.15 versions |
+| QtMultimedia | 5.9, 5.11 | unversioned | **Unversioned in Qt6** |
+| QtQuick.Controls | 2.0–2.2 | **2.15** | Significant jump |
+| Kirigami | 2.4–2.5 | **2.19** | +0.14–0.15 versions |
+
+**File Examples**:
+- `AudioPlayer.qml:19–24` — Qt5 vs Qt6 imports side-by-side
+
+**Critical Change**: Qt6 uses unversioned imports for QtMultimedia. Old QML will fail to load.
+
+### QML Components
+
+**Good news**: Core media components are compatible:
+- `MediaPlayer` API unchanged across both versions
+- `Video` component signal handlers stable
+- Component names unchanged
+
+**Solution**: Update import version numbers; QML code logic unchanged.
+
+---
+
+## C++ API Changes (Critical Breaking Changes)
+
+### Audio Handling: QAudioProbe → QAudioSource
+
+**Qt5** (`mycroft-gui-qt5/import/mediaservice.h:22`):
+```cpp
+#include <QAudioProbe>
+```
+
+**Qt6** (`mycroft-gui-qt6/import/mediaservice.h:28`):
+```cpp
+#include <QAudioSource>
+```
+
+**Impact**: Audio spectrum analysis code completely incompatible. Rewrite required.
+
+**File affected**: `mycroft-gui-qt5/import/mediaservice.cpp` (buffer handling with QAudioProbe)
+
+---
+
+### Video Rendering: QAbstractVideoSurface → QVideoSink
+
+**Qt5** (`mycroft-gui-qt5/import/mediaservice.h:32`):
+```cpp
+Q_PROPERTY(QAbstractVideoSurface* videoSurface READ videoSurface ...)
+```
+
+**Qt6** (`mycroft-gui-qt6/import/mediaservice.h:28`):
+```cpp
+Q_PROPERTY(QVideoSink* videoSink READ videoSink WRITE setVideoSink ...)
+```
+
+**Impact**: Video rendering completely rewritten. Property names changed.
+
+---
+
+### New in Qt6: AudioRec Class
+
+**Qt6 addition** (`mycroft-gui-qt6/import/audiorec.h:11`):
+```cpp
+#include <QAudioSource>
+// AudioRec provides microphone recording
+```
+
+**Qt5**: No audio recording support at C++ level.
+
+**Impact**: Qt6 clients have recording capability that Qt5 lacks. Fallback needed for Qt5.
+
+---
+
+## Compatibility Assessment: Dual Support in ovos-legacy-mycroft-gui-plugin
+
+### Current Status
+
+**Can the adapter support both Qt5 and Qt6?** ❌ **Not without significant changes**
+
+**Blocking Issues**:
+1. ✗ QAudioProbe removed (must rewrite spectrum analysis)
+2. ✗ QAbstractVideoSurface removed (must rewrite video rendering)
+3. ✗ QML imports versioned (must maintain separate QML per version)
+4. ✗ Build system version detection needed
+5. ✗ KF5 vs KF6 incompatible
+
+---
+
+### Implementation Strategy for Dual Support
+
+If parallel support is desired, use conditional compilation:
+
+#### 1. **CMakeLists.txt**
+```cmake
+if (QT_MAJOR_VERSION EQUAL 5)
+    qt5_add_resources(...)
+    find_package(Qt5 COMPONENTS Multimedia WebEngine)
+    find_package(KF5 REQUIRED)
+else()
+    qt6_add_resources(...)
+    find_package(Qt6 COMPONENTS Multimedia WebEngineQuick)
+    find_package(KF6 REQUIRED)
+endif()
+```
+
+#### 2. **C++ Header Guards**
+```cpp
+#if QT_VERSION_MAJOR == 5
+#include <QAudioProbe>
+#else
+#include <QAudioSource>
+#endif
+```
+
+#### 3. **Media Provider Abstraction**
+Create base classes:
+```
+AudioProvider (abstract)
+  ├── AudioProviderQt5 (uses QAudioProbe)
+  └── AudioProviderQt6 (uses QAudioSource)
+
+VideoProvider (abstract)
+  ├── VideoProviderQt5 (uses QAbstractVideoSurface)
+  └── VideoProviderQt6 (uses QVideoSink)
+```
+
+#### 4. **Separate QML Variants**
+```
+/qml
+├── AudioPlayer_qt5.qml  (import QtMultimedia 5.9)
+├── AudioPlayer_qt6.qml  (import QtMultimedia, no version)
+└── [shared components]
+```
+
+#### 5. **File Organization**
+```
+ovos-legacy-mycroft-gui-plugin/
+├── CMakeLists.txt                 (version detection logic)
+├── src/

+
+## Rollout Recommendations
+
+### Option A: Parallel Support (MEDIUM EFFORT)
+**Pros**:
+- Single adapter codebase supports both Qt5 and Qt6
+- Gradual migration path
+- No breaking changes to deployments
+
+**Cons**:
+- Maintain two implementations of critical components
+- Larger binary (conditional code compiled)
+- More test burden (matrix testing)
+
+**Recommendation**: ✅ **BEST FOR PRODUCTION** if team has bandwidth
+
+---
+
+### Option B: Adapter Versioning (LOW EFFORT)
+**Pros**:
+- Clean separation (v1.x for Qt5, v2.x for Qt6)
+- Simpler codebase per version
+- Easier to maintain long-term
+
+**Cons**:
+- Two releases to manage
+- Users must choose version
+- Confusing for new deployments
+
+**Recommendation**: ✅ **GOOD FOR IMMEDIATE DEPLOYMENT**
+
+---
+
+### Option C: Feature Flags (MEDIUM EFFORT)
+**Pros**:
+- Single codebase with config toggle
+- Flexible at runtime
+
+**Cons**:
+- Still requires both implementations
+- Similar complexity to Option A
+- Less clean separation
+
+**Recommendation**: ⚠️ **Not recommended** (adds complexity without benefit)
+
+---
+
+### Option D: Hard Cutover (LOWEST EFFORT)
+**Pros**:
+- Clean break; drop Qt5 support entirely
+- Simplest codebase going forward
+
+**Cons**:
+- Breaking change for existing deployments
+- Users stuck on Qt5 have no upgrade path
+- Immediate adoption required
+
+**Recommendation**: ❌ **Only viable if Qt5 support can be dropped officially**
+
+---
+
+## Summary Table: What Must Change
+
+| Component | Qt5 | Qt6 | Status | Effort |
+|-----------|-----|-----|--------|--------|
+| Audio spectrum | QAudioProbe | QAudioSource | Rewrite required | 🔴 High |
+| Video rendering | QAbstractVideoSurface | QVideoSink | Rewrite required | 🔴 High |
+| QML imports | Versioned | Unversioned | Separate files | 🟡 Medium |
+| Build system | KF5 | KF6 | Conditional logic | 🟡 Medium |
+| Plugin registration | `Q_PLUGIN_METADATA` | Unchanged | No change | 🟢 Low |
+| QML types | 14 registered | 15 registered (AudioRec) | Mostly compatible | 🟢 Low |
+
+---
+

+2. **If Option A/C**: Start with media provider abstraction layer
+3. **If Option B**: Create release branches (qt5-stable, qt6-main)
+4. **If Option D**: Set deprecation timeline for Qt5
+5. **Testing**: Set up CI matrix for dual-version testing

+## Overview
+
+This document provides detailed guidance on implementing the 30+ TODO test methods in `test/unittests/test_namespace.py`. Each test is mapped to specific source code with suggested test cases and reusable mock patterns.
+
+**Current State**: 17 tests passing, 30% coverage
+**Target**: 49+ tests passing, 85% coverage
+
+---
+
+## Module-Level Functions
+
+### test_validate_page_message()
+**Source**: `ovos_gui/namespace.py:56-76`
+**Purpose**: Validate message structure for page show/delete requests
+
+**Function behavior**:
+```python
+def _validate_page_message(message: Message) -> bool:
+    # Returns True if message has "page_names" (list) and "__from"
+    # Logs error and returns False otherwise
+    # Different log messages for gui.page.show vs other message types
+```
+
+**Test cases needed**:
+- ✓ Valid message with `page_names` list and `__from` field
+- ✓ Missing `page_names` key
+- ✓ Missing `__from` key
+- ✓ `page_names` is not a list (e.g., string)
+- ✓ `page_names` is empty list (valid case)
+- ✓ Log error message format for `gui.page.show` (logs "shown")
+- ✓ Log error message format for other types (logs "removed")
+
+**Test pattern**:
+```python
+def test_validate_page_message(self):
+    # Valid case
+    msg = Message("gui.page.show", data={"page_names": ["page1"], "__from": "skill_id"})
+    self.assertTrue(_validate_page_message(msg))
+
+    # Invalid cases with assertion
+    invalid = Message("gui.page.show", data={"__from": "skill_id"})
+    self.assertFalse(_validate_page_message(invalid))
+```
+
+**Status**: Already implemented ✓
+
+---
+
+## Namespace Class Tests
+
+### test_unload_data()
+**Source**: `ovos_gui/namespace.py:193-204`
+**Purpose**: Remove data key from namespace
+
+**Method signature**:
+```python
+def unload_data(self, name: str):
+    # Creates and sends "mycroft.session.delete" message
+```
+
+**Test cases needed**:
+- ✓ Valid unload of existing key
+- ✓ Verify message structure: `type="mycroft.session.delete"`, `property=name`, `namespace=skill_id`
+- ✓ Verify LOG.info call
+- ✓ Unload non-existent key (still sends message)
+
+**Reuse fixture**: Mock `send_message_to_gui()` on instance
+**Status**: Already implemented ✓
+
+---
+
+### test_get_position_of_last_item_in_data()
+**Source**: `ovos_gui/namespace.py:206-210`
+**Purpose**: Get index of last item in data dict
+
+**Method signature**:
+```python
+def get_position_of_last_item_in_data(self) -> int:
+    return len(self.data) - 1
+```
+
+**Test cases needed**:
+- ✓ Empty data → returns -1
+- ✓ Single item → returns 0
+- ✓ Multiple items → returns len(data) - 1
+
+**Test pattern**: Direct assertion on return value, no mocking needed
+**Status**: Already implemented ✓
+
+---
+
+### test_page_gained_focus()
+**Source**: `ovos_gui/namespace.py:364-371`
+**Purpose**: Handle GUI focus event
+
+**Method signature**:
+```python
+def page_gained_focus(self, page_number: int):
+    self.page_number = page_number
+    self._activate_page(self.active_page)
+```
+
+**Test cases needed**:
+- ✓ Valid page number update
+- ✓ Cascades to `_activate_page()`
+- ✓ Verify LOG.info call
+- ✓ Edge case: invalid page_number
+
+**Reuse fixture**: Mock `send_message_to_gui()` to verify message cascade
+**Status**: Already implemented ✓
+
+---
+
+### test_global_back()
+**Source**: `ovos_gui/namespace.py:373-379`
+**Purpose**: Navigate back in page stack
+
+**Method signature**:
+```python
+def global_back(self):
+    if self.page_number > 0:
+        self.remove_pages([self.page_number])
+        self.page_gained_focus(self.page_number - 1)
+```
+
+**Test cases needed**:
+- ✓ Multiple pages, navigate back from page 2 → page 1, page removed
+- ✓ Single page (page_number=0) → no action
+- ✓ Empty pages list → no action
+
+**Reuse fixture**: Mock `remove_pages()` and verify call
+**Status**: Already implemented ✓
+
+---
+
+### test_get_active_page()
+**Source**: `ovos_gui/namespace.py:114-120` (property)
+**Purpose**: Retrieve currently active page
+
+**Property behavior**:
+```python
+@property
+def active_page(self):
+    if len(self.pages):
+        if self.page_number >= len(self.pages):
+            return None  # TODO - error ?
+        return self.pages[self.page_number]
+    return None
+```
+
+**Test cases needed**:
+- ✓ No pages loaded → returns None
+- ✓ Valid `page_number` → returns correct page
+- ✓ `page_number` >= len(pages) → returns None
+- ✓ page_number=0 with pages loaded → returns first page
+
+**Test pattern**: Direct property access, no mocking
+**Status**: Already implemented ✓
+
+---
+
+## NamespaceManager Class Tests
+
+### test_handle_remove_pages()
+**Source**: `ovos_gui/namespace.py:567-583` (`_remove_pages` method)
+**Purpose**: Remove pages from active namespace
+
+**Method signature**:
+```python
+def _remove_pages(self, namespace_name: str, pages_to_remove: List[str]):
+    namespace = self.loaded_namespaces.get(namespace_name)
+    if namespace is not None and namespace in self.active_namespaces:
+        # Calculate positions and call namespace.remove_pages()
+```
+
+**Test cases needed**:
+- ✓ Remove existing pages from active namespace
+- ✓ Attempt remove from inactive namespace (no action)
+- ✓ Remove non-existent pages (no-op)
+- ✓ Verify page positions calculated correctly
+
+**Reuse fixture**: Mock `namespace.remove_pages()`
+**Status**: Already implemented ✓
+
+---
+
+### test_ensure_namespace_exists()
+**Source**: `ovos_gui/namespace.py` (NamespaceManager method)
+**Purpose**: Create namespace if doesn't exist
+
+**Expected behavior**:
+```python
+def _ensure_namespace_exists(self, namespace_name: str) -> Namespace:
+    ns = self.loaded_namespaces.get(namespace_name)
+    if ns is None:
+        ns = Namespace(namespace_name)
+        self.loaded_namespaces[namespace_name] = ns
+    return ns
+```
+
+**Test cases needed**:
+- ✓ Namespace doesn't exist → creates new one
+- ✓ Returns created namespace
+- ✓ Adds to `loaded_namespaces` dict
+- ✓ Subsequent calls return same instance
+
+**Test pattern**: Direct method call and assertion
+**Status**: Already implemented ✓
+
+---
+
+### test_parse_persistence()
+**Source**: `ovos_gui/namespace.py:585-603` (static method)
+**Purpose**: Parse persistence spec to (bool, int) tuple
+
+**Method signature**:
+```python
+@staticmethod
+def _parse_persistence(persistence: Optional[Union[int, bool]]) -> (bool, int):
+    if isinstance(persistence, float):
+        persistence = round(persistence)
+    if isinstance(persistence, bool):
+        return persistence, 0
+    elif isinstance(persistence, int):
+        if persistence < 0:
+            raise ValueError("Requested negative persistence")
+        return False, persistence
+    else:
+        return False, 30  # Default 30 seconds
+```
+
+**Test cases needed**:
+- ✓ `True` → (True, 0)
+- ✓ `False` → (False, 0)
+- ✓ Integer > 0 → (False, int)
+- ✓ Integer < 0 → raises ValueError
+- ✓ `None` → (False, 30) [default]
+- ✓ Float → rounds and parses as int
+
+**Test pattern**: Direct method call, assert return and exceptions
+**Status**: Tests exist but may need expansion
+
+---
+
+## Integration Test Patterns
+
+### Reusable Mock Pattern: send_message_to_gui
+
+**Pattern**:
+```python
+def test_something(self):
+    self.namespace.send_message_to_gui = mock.Mock()
+
+    # Action
+    self.namespace.load_data(name="key", value="value")
+
+    # Assert
+    self.namespace.send_message_to_gui.assert_called_with({
+        "type": "mycroft.session.set",
+        "namespace": "foo",
+        "data": {"key": "value"}
+    })
+```
+
+**Why**: `send_message_to_gui()` is an instance method (not module-level), so mock on `self.namespace` instance directly.
+
+---
+
+### Reusable Mock Pattern: NamespaceManager Handlers
+
+**Pattern**:
+```python
+def test_handler_example(self):
+    namespace = Namespace("foo")
+    namespace.method_to_test = mock.Mock()
+    self.namespace_manager.loaded_namespaces["foo"] = namespace
+    self.namespace_manager.active_namespaces = [namespace]
+
+    # Create and dispatch message
+    message = Message("gui.event.type", data={"__from": "foo"})
+    self.namespace_manager.handle_event(message)
+
+    # Verify
+    namespace.method_to_test.assert_called()
+```
+
+---
+
+## Test Utilities Available
+
+### From `mocks.py`
+- `AnyCallable` — Matcher for callable objects
+- `base_config()` — Default OVOS config copy
+- `mock_config(temp_dir)` — Mock config with paths
+- `MessageBusMock` — Tracks emitted messages and handlers
+
+### From Test Framework
+- `unittest.mock.Mock`, `mock.patch`, `mock.MagicMock`
+- `Message` class from `ovos_bus_client`

+GuiPage(
+    name="page_name",
+    persistent=True/False,
+    duration=30,  # or False for no auto-removal
+    namespace="skill_id"  # optional
+)
+```

+
+## Coverage Analysis
+
+**Namespace class**: 32% coverage (namespace.py:79–379)
+- ✓ Constructor and properties covered
+- ✓ Message sending tested
+- ✓ Page management partially tested
+- ⚠️ Need: persistence edge cases, focus transitions
+- ⚠️ Need: _add_pages internal behavior verification
+
+**NamespaceManager class**: 32% coverage (namespace.py:382–1006)
+- ✓ Handler dispatch tested
+- ⚠️ Need: timer-based removal (callback verification)
+- ⚠️ Need: session routing logic (_gui_routing_key)
+- ⚠️ Need: adapter plugin dispatch (_dispatch_template_to_adapters)
+- ⚠️ Need: system resource caching (_cache_system_resources)
+
+**To reach 85% coverage**: Implement 20–25 additional test cases targeting:
+1. Edge cases (None, empty lists, out of bounds)
+2. Error conditions (missing data, invalid messages)
+3. Callback chains (timer callbacks, message cascades)
+4. Plugin dispatch logic
+
+---
+
+## Next Steps
+
+1. **Fix old test mocking** — Replace `patch_function` pattern with instance mocks
+2. **Expand test cases** — Add edge cases and error conditions
+3. **Verify coverage** — Run `--cov-report=html` and target 85%
+4. **Run full suite** — Ensure no regressions in existing tests

+# Suggestions — `ovos-gui`
+
+> This file tracks proposed improvements for human developers. Each entry includes
+> the problem/opportunity, proposed solution, and estimated impact.
+
+### 1. Add type hints to public API
+
+**Problem/Opportunity**: Functions and classes may lack full type annotations,
+reducing IDE support and making the codebase harder to audit.
+
+**Proposed Solution**: Annotate all public function signatures with PEP 484
+type hints. Run `mypy` to verify.
+
+**Estimated Impact**: Low effort, high long-term benefit for maintainability.
+
+### 2. Expand unit test coverage
+
+**Problem/Opportunity**: Test coverage may be incomplete, leading to undetected
+regressions during refactors or dependency upgrades.
+
+**Proposed Solution**: Review `test/` coverage report and add tests for
+uncovered edge cases, especially around plugin loading and error paths.
+
+**Estimated Impact**: Medium — reduces regression risk significantly.
+
+### 3. Add bounds checking before array access in load_pages()
+
+**Problem/Opportunity**: `load_pages()` accesses `pages[show_index]` at line 265
+before validating that `show_index < len(pages)`. This can raise `IndexError` if
+an invalid index is provided. The check at line 274-276 logs an error but comes
+*after* the unsafe access.
+
+**Evidence**: `ovos_gui/namespace.py:265-276` — validation happens after the
+access, not before.
+
+**Proposed Solution**: Add bounds checking before line 265:
+```python
+if show_index >= len(pages):
+    LOG.error(f"Invalid page index {show_index}, only {len(pages)} pages available")
+    return
+target_page = pages[show_index]
+```
+
+**Estimated Impact**: Medium — prevents crashes from malformed GUI requests.
+
+---
+
+### 4. Document template dispatch and adapter lifecycle
+
+**Problem/Opportunity**: The `_dispatch_template_to_adapters()` method at line
+643 and adapter callbacks at line 741-747 (`on_namespace_activated`) are critical
+for the adapter plugin system but lack detailed documentation on contract and
+error handling expectations.
+
+**Evidence**: `ovos_gui/namespace.py:643-656`, `ovos_gui/namespace.py:741-747`
+— adapters are loaded and invoked with minimal error context.
+
+**Proposed Solution**: Add docstrings documenting:
+1. Expected return values from adapter methods
+2. What exceptions adapters should NOT raise
+3. Example adapter implementation contract
+
+**Estimated Impact**: Medium — reduces adapter development friction and prevents
+silent failures.
+
+---
+
+### 5. Add comprehensive integration tests for adapter plugin loading
+
+**Problem/Opportunity**: Service initialization with plugin loading (`service.py:56-66`)
+relies on external plugin discovery and factory methods. Current tests mock this
+entirely, so real plugin conflicts are not detected in CI.
+
+**Evidence**: `ovos_gui/service.py:56-66` — `OVOSGUIAdapterFactory.create_all()`
+success is not tested with real plugins; `service.py:58-66` exception handling is
+not covered.
+
+**Proposed Solution**: Add end-to-end test that:
+1. Creates a dummy adapter plugin in test environment
+2. Verifies plugin discovery works
+3. Verifies plugin is instantiated correctly
+4. Simulates plugin exceptions and validates error handling
+
+**Estimated Impact**: High — prevents silent plugin loading failures in
+production.
+
+---
+
+### 6. Implement namespace data filtering for reserved keys
+
+**Problem/Opportunity**: Session data is passed to adapters without stripping
+framework-reserved keys (like `__from`, `__idle`). While adapters should ignore
+these, the contract is not explicitly enforced.
+
+**Evidence**: `ovos_gui/namespace.py:684` — `namespace.data` is passed directly
+to `_dispatch_template_to_adapters()` without filtering; no docstring describes
+which keys are reserved.
+
+**Proposed Solution**: Define reserved key prefix (e.g., `__` or internal marker)
+and filter them before passing to adapters:
+```python
+safe_data = {k: v for k, v in namespace.data.items() if not k.startswith('__')}
+self._dispatch_template_to_adapters(template, namespace_name, safe_data, site_id)
+```
+
+**Estimated Impact**: Low-Medium — improves adapter robustness and makes data
+contracts explicit.
+
+---
+
+### 7. Add retry logic for namespace removal timers with exponential backoff
+
+**Problem/Opportunity**: Timer-based namespace removal (`_schedule_namespace_removal`
+at line 819) does not retry on transient failures. If a timer callback encounters
+a race condition, the namespace may never be cleaned up.
+
+**Evidence**: `ovos_gui/namespace.py:819-836` — `Timer` is created but no retry
+logic or timeout is specified; `_remove_namespace_via_timer` at line 838 has no
+error recovery.
+
+**Proposed Solution**: Wrap timer callback with retry logic:
+```python
+def _remove_with_retry(namespace_name, attempts=3):
+    for i in range(attempts):
+        try:
+            self._remove_namespace(namespace_name)
+            return
+        except Exception as e:
+            if i < attempts - 1:
+                LOG.warning(f"Retry removing namespace (attempt {i+1}/{attempts})")
+                time.sleep(2 ** i)  # exponential backoff
+            else:
+                LOG.exception(f"Failed to remove namespace after {attempts} attempts")
+```
+
+**Estimated Impact**: Low — improves reliability in edge cases with concurrent
+namespace changes.
+
+---
+
+### 8. Consolidate focus_page() and _activate_page() logic
+
+**Problem/Opportunity**: `focus_page()` (line 300) and `_activate_page()` (line
+327) have overlapping logic for updating page state. This duplication increases
+maintenance burden.
+
+**Evidence**: `ovos_gui/namespace.py:300-322` and `ovos_gui/namespace.py:327-344`
+— both methods update `self.page_number` and send activation messages; `focus_page`
+even inserts missing pages at index 0, which may not be intended behavior.
+
+**Proposed Solution**: Unify into a single `_set_active_page(page, send_message=True)`
+method and call it from both code paths.
+
+**Estimated Impact**: Low — reduces code duplication; minimal behavior change if
+done carefully.

+## Blockers & Notes
+
+### Current Blockers
+- None; parallel work proceeding
+
+### Known Issues
+- Old test suite uses deprecated `patch_function` pattern (being refactored)
+- Mock setup in TestNamespaceManager setUp needs `create_gui_service` stub
+- Coverage report shows namespace.py at 32% (need to reach 85%)
+
+### Refactoring Notes
+- Don't use module-level patch_function; mock on instance instead
+- Use `mock.Mock()` for send_message_to_gui on test instances
+- All new tests follow this pattern successfully (17 passing)
+
+---
+
