+## Component Description
+
+### Responsibilities
+- Manage trajectory results per flight
+- Track frame refinements and changes
+- Trigger per-frame Route API updates via G03
+- Send incremental updates via F14 SSE
+- Maintain result versioning for audit trail
+- Convert optimized poses to GPS coordinates
+
+### Scope
+- Result state management
+- Route API integration
+- SSE event triggering
+- Incremental update detection
+- Result persistence
+
+## API Methods
+
+### `update_frame_result(flight_id: str, frame_id: int, result: FrameResult) -> bool`
+
+**Description**: Updates result for a processed frame.
+
+**Called By**:
+- Main processing loop (after each frame)
+- F10 Factor Graph (after refinement)
+
+**Input**:
+```python
+flight_id: str
+frame_id: int
+result: FrameResult:
+    gps_center: GPSPoint
+    altitude: float
+    heading: float
+    confidence: float
+    timestamp: datetime
+    refined: bool
+    objects: List[ObjectLocation]  # From external detector
+```
+
+**Output**: `bool` - True if updated
+
+**Processing Flow**:
+1. Store result in memory/database
+2. Call publish_to_route_api()
+3. Call G14.send_frame_result()
+4. Update flight statistics
+
+**Test Cases**:
+1. New frame result → stored and published
+2. Refined result → updates existing, marks refined=True
+
+---
+
+### `publish_to_route_api(flight_id: str, frame_id: int) -> bool`
+
+**Description**: Sends frame GPS to Route API via G03 client.
+
+**Called By**:
+- Internal (after update_frame_result)
+
+**Input**:
+```python
+flight_id: str
+frame_id: int
+```
+
+**Output**: `bool` - True if published successfully
+
+**Processing Flow**:
+1. Get result for frame_id
+2. Convert to Waypoint format
+3. Call G03.update_route_waypoint()
+4. Handle errors (retry if transient)
+
+**Test Cases**:
+1. Successful publish → Route API updated
+2. Route API unavailable → logs error, continues
+
+---
+
+### `get_flight_results(flight_id: str) -> FlightResults`
+
+**Description**: Retrieves all results for a flight.
+
+**Called By**:
+- F01 REST API (results endpoint)
+- Testing/validation
+
+**Input**: `flight_id: str`
+
+**Output**:
+```python
+FlightResults:
+    flight_id: str
+    frames: List[FrameResult]
+    statistics: FlightStatistics
+```
+
+**Test Cases**:
+1. Get all results → returns complete trajectory
+
+---
+
+### `mark_refined(flight_id: str, frame_ids: List[int]) -> bool`
+
+**Description**: Marks frames as refined after batch optimization.
+
+**Called By**:
+- F10 Factor Graph (after asynchronous refinement)
+
+**Input**:
+```python
+flight_id: str
+frame_ids: List[int]  # Frames with updated poses
+```
+
+**Output**: `bool`
+
+**Processing Flow**:
+1. For each frame_id:
+   - Get refined pose from F10
+   - Convert to GPS via G12
+   - Update result with refined=True
+   - publish_to_route_api()
+   - Call G14.send_refinement()
+
+**Test Cases**:
+1. Batch refinement → all frames updated and published
+
+---
+
+### `get_changed_frames(flight_id: str, since: datetime) -> List[int]`
+
+**Description**: Gets frames changed since timestamp (for incremental updates).
+
+**Called By**:
+- F14 SSE Event Streamer (for reconnection replay)
+
+**Input**:
+```python
+flight_id: str
+since: datetime
+```
+
+**Output**: `List[int]` - Frame IDs changed since timestamp
+
+**Test Cases**:
+1. Get changes → returns only modified frames
+2. No changes → returns empty list
+
+## Integration Tests
+
+### Test 1: Per-Frame Processing
+1. Process frame 237
+2. update_frame_result() → stores result
+3. Verify publish_to_route_api() called
+4. Verify F14 SSE event sent
+
+### Test 2: Batch Refinement
+1. Process 100 frames
+2. Factor graph refines frames 10-50
+3. mark_refined([10-50]) → updates all
+4. Verify Route API updated
+5. Verify SSE refinement events sent
+
+### Test 3: Incremental Updates
+1. Process frames 1-100
+2. Client disconnects at frame 50
+3. Client reconnects
+4. get_changed_frames(since=frame_50_time)
+5. Client receives frames 51-100
+
+## Non-Functional Requirements
+
+### Performance
+- **update_frame_result**: < 50ms
+- **publish_to_route_api**: < 100ms (non-blocking)
+- **get_flight_results**: < 200ms for 2000 frames
+
+### Reliability
+- Result persistence survives crashes
+- Guaranteed at-least-once delivery to Route API
+- Idempotent updates
+
+## Dependencies
+
+### Internal Components
+- G03 Route API Client
+- F10 Factor Graph Optimizer
+- F12 Coordinate Transformer
+- F14 SSE Event Streamer
+- F17 Database Layer
+
+### External Dependencies
+- None
