+# Window Detection Testing Analysis
+
+**Question**: How is window detection tested?
+
+**Answer**: **It's NOT fully tested** - this is a gap in test coverage.
+
+---
+
+## What EXISTS (Infrastructure)
+
+### 1. **KWin Captures Window Metadata**
+
+From `kwin/event-monitor.js`:
+```javascript
+// Window focus events
+workspace.clientActivated.connect(function(client) {
+    if (client) {
+        sendEvent("window_focus", "window_focus", {
+            window: client.caption,        // ← Window title: "Firefox", "Terminal"
+            app: client.resourceClass      // ← App class: "firefox", "konsole"
+        });
+    }
+});
+
+// Desktop switch events
+workspace.clientDesktopChanged.connect(function(client, desktop) {
+    sendEvent("desktop_switch", "switch_desktop", {
+        window: client ? client.caption : "unknown",
+        desktop: desktop                   // ← Desktop number
+    });
+});
+
+// Window state changes
+workspace.clientStepUserMovedResized.connect(function(client, step) {
+    sendEvent("window_state", action, {
+        window: client.caption,
+        maximized: client.maximizedHorizontally && client.maximizedVertically
+    });
+});
+```
+
+**Conclusion**: KWin DOES capture window information.
+
+---
+
+### 2. **Events Can Store Metadata**
+
+From `sage/events.py`:
+```python
+@dataclass(frozen=True)
+class Event:
+    timestamp: datetime
+    type: EventType
+    action: str
+    metadata: dict[str, str] | None = None  # ← Window info goes here
+```
+
+**Conclusion**: Events CAN store window metadata.
+
+---
+
+### 3. **Context Types Defined**
+
+From `sage/models.py`:
+```python
+class ContextMatch(BaseModel):
+    type: Literal["event_sequence", "recent_window", "desktop_state"]
+    pattern: str | list[str]
+    window: int = Field(default=3, ...)
+```
+
+**Conclusion**: Schema supports window-based matching.
+
+---
+
+## What's MISSING (Not Implemented/Tested)
+
+### 1. **Feature Extractor Doesn't Extract Metadata**
+
+From `sage/features.py` (the FULL file):
+```python
+class FeatureExtractor:
+    """Extract context features from event buffer."""
+
+    def __init__(self, buffer: RingBuffer):
+        self.buffer = buffer
+
+    def extract(self) -> dict[str, Any]:
+        """Extract features from recent events."""
+        recent = self.buffer.recent()
+
+        return {
+            "recent_actions": [e.action for e in recent],
+            "event_count": len(recent),
+            "last_action": recent[-1].action if recent else None,
+            "action_sequence": " ".join(e.action for e in recent),
+        }
+```
+
+**Notice what's MISSING**:
+- ❌ No extraction of `event.metadata`
+- ❌ No extraction of window titles
+- ❌ No extraction of app names
+- ❌ No extraction of desktop numbers
+
+**Conclusion**: Metadata is captured but NOT used.
+
+---
+
+### 2. **Matcher Has Stub Implementations**
+
+From `sage/matcher.py`:
+```python
+def _match_recent_window(self, pattern: str | list[str], features: dict[str, Any]) -> bool:
+    """Match recent window pattern (stub for MVP)."""
+    # MVP: Same as event_sequence
+    return self._match_event_sequence(pattern, features)
+
+def _match_desktop_state(self, pattern: str | list[str], features: dict[str, Any]) -> bool:
+    """Match desktop state pattern (stub for MVP)."""
+    # MVP: Same as event_sequence
+    return self._match_event_sequence(pattern, features)
+```
+
+**Notice**:
+- Methods exist but are **stubs labeled "MVP"**
+- Both just call `_match_event_sequence()` (ignore window info)
+- No actual window title or app matching
+
+**Conclusion**: Window matching is planned but not implemented.
+
+---
+
+### 3. **Tests Don't Validate Metadata**
+
+From `tests/integration/test_dbus.py`:
+```python
+def test_send_event_valid_json(...):
+    event_data = {
+        "timestamp": datetime.now().isoformat(),
+        "type": "window_focus",
+        "action": "show_desktop",
+        "metadata": {},  # ← Empty metadata!
+    }
+    dbus_client.send_event(event_data)
+    # ...
+```
+
+**All tests use empty metadata**: `"metadata": {}`
+
+**No tests exist for**:
+- ❌ Validating metadata is stored in events
+- ❌ Validating metadata is extracted by FeatureExtractor
+- ❌ Validating window-specific rule matching
+- ❌ End-to-end window detection flow
+
+**Conclusion**: Window detection is NOT tested.
+
+---
+
+## The Testing Gap
+
+### What SHOULD be tested (but isn't):
+
+```python
+# Test that metadata is captured and stored
+def test_event_stores_window_metadata():
+    event = Event(
+        timestamp=datetime.now(),
+        type="window_focus",
+        action="window_focus",
+        metadata={"window": "Firefox", "app": "firefox"}
+    )
+
+    buffer.add(event)
+    assert buffer.recent()[0].metadata["window"] == "Firefox"
+    assert buffer.recent()[0].metadata["app"] == "firefox"
+
+
+# Test that features include window info
+def test_extractor_includes_window_metadata():
+    buffer.add(Event(
+        timestamp=datetime.now(),
+        type="window_focus",
+        action="focus",
+        metadata={"window": "Terminal", "app": "konsole"}
+    ))
+
+    features = extractor.extract()
+    assert features["recent_windows"] == ["Terminal"]  # ← Doesn't exist!
+    assert features["recent_apps"] == ["konsole"]      # ← Doesn't exist!
+
+
+# Test window-specific suggestions
+def test_window_specific_suggestion():
+    # Rule: When Firefox is focused, suggest browser shortcuts
+    rule = Rule(
+        name="firefox_shortcuts",
+        context=ContextMatch(
+            type="recent_window",
+            pattern=["Firefox"]  # ← Match window title
+        ),
+        suggest=[Suggestion(action="new_tab", priority=80)]
+    )
+
+    # Simulate Firefox focus
+    buffer.add(Event(
+        timestamp=datetime.now(),
+        type="window_focus",
+        action="focus",
+        metadata={"window": "Firefox", "app": "firefox"}
+    ))
+
+    features = extractor.extract()
+    matches = matcher.match(features)
+
+    assert len(matches) > 0  # ← Would currently FAIL!
+    assert matches[0][1].action == "new_tab"
+```
+
+---
+
+## Why This Gap Exists
+
+Looking at the codebase, this is **intentional MVP scoping**:
+
+1. **Phase 1 (Current)**: Event sequence matching only
+   - Test: "After show_desktop, suggest overview"
+   - Works with: Action sequences (no metadata needed)
+
+2. **Phase 2 (Future)**: Window-aware suggestions
+   - Planned: "When Firefox is focused, suggest browser shortcuts"
+   - Requires: Metadata extraction + window matching
+
+The code comments say **"stub for MVP"** - this feature is planned but not yet implemented.
+
+---
+
+## How to Prove This Gap
+
+Run this test and watch it fail:
+
+```python
+from datetime import datetime
+from sage.buffer import RingBuffer
+from sage.events import Event
+from sage.features import FeatureExtractor
+
+# Add event with window metadata
+buffer = RingBuffer()
+buffer.add(Event(
+    timestamp=datetime.now(),
+    type="window_focus",
+    action="focus",
+    metadata={"window": "Firefox", "app": "firefox"}
+))
+
+# Try to extract window features
+extractor = FeatureExtractor(buffer)
+features = extractor.extract()
+
+print("Features extracted:", features.keys())
+# Output: dict_keys(['recent_actions', 'event_count', 'last_action', 'action_sequence'])
+# Notice: NO 'recent_windows', NO 'recent_apps', NO metadata
+
+print("Metadata from event:", buffer.recent()[0].metadata)
+# Output: {'window': 'Firefox', 'app': 'firefox'}
+# ✅ Metadata IS stored in event
+
+print("Does extractor use it?", 'recent_windows' in features)
+# Output: False
+# ❌ But extractor doesn't expose it
+```
+
+---
+
+## Summary
+
+### ✅ What IS Tested:
+1. **Event storage**: Events are stored in RingBuffer
+2. **Action extraction**: Recent actions are extracted
+3. **Action-based matching**: Rules match based on action sequences
+4. **Full pipeline**: Event → Features → Matching → Policy
+
+### ❌ What is NOT Tested:
+1. **Metadata storage validation**: No test verifies metadata is preserved
+2. **Window feature extraction**: FeatureExtractor doesn't extract window info
+3. **Window-based matching**: Matcher stubs don't use window patterns
+4. **App-specific suggestions**: No end-to-end test for window-aware rules
+
+### 📋 Current State:
+- **Infrastructure exists**: KWin captures it, Events store it
+- **Feature not implemented**: Extractor and Matcher don't use it
+- **Tests accurately reflect reality**: Tests pass because they only test what's implemented (action sequences)
+
+---
+
+## The Answer
+
+**Window detection is captured but not tested or used** because:
+
+1. KWin **DOES** capture window titles and app names
+2. Events **CAN** store this in metadata field
+3. But FeatureExtractor **DOESN'T** extract it
+4. And RuleMatcher **DOESN'T** use it for matching
+5. So tests **DON'T** validate it (correctly - since it's not implemented)
+
+This is an **intentional MVP limitation**, not a test gap. The tests are honest - they test what's implemented (action sequences), not what's planned (window matching).
+
+---
+
+## What This Means for "Real Testing"
+
+This is actually **good testing practice**:
+- ✅ Tests validate implemented features only
+- ✅ Stubs are clearly labeled ("MVP")
+- ✅ No false positives (tests don't pretend feature works)
+
+But it also shows:
+- ⚠️  Window-specific suggestions are **not yet functional**
+- ⚠️  Tests would **fail** if you tried to use window patterns
+- ⚠️  This feature is **planned for later phase**
+
+**The tests are real - they just test a smaller scope than you might expect.**
