 ## Key Components
 
 ### Recorder
-Main interface for capturing GUI interactions:
-- `__enter__` / `__exit__` - Context manager lifecycle
-- `record_events()` - Main capture loop
-- `event_count` - Total captured events
+Multi-process recording system (copied from legacy OpenAdapt):
+- `Recorder(capture_dir, task_description)` - Context manager
+- Internally runs `record()` which spawns reader threads + writer processes
+- Action-gated video capture (only encode frames when user acts)
+- Stop via context manager exit or stop sequences (default: `llqq`)
 
-### Capture
+### CaptureSession / Capture
 Load and query recorded captures:
-- `Capture.load(path)` - Load from directory
-- `capture.events()` - Iterator over raw events
-- `capture.actions()` - Iterator over processed actions
+- `Capture.load(path)` - Load from capture directory (reads `recording.db`)
+- `capture.raw_events()` - List of Pydantic events from SQLAlchemy DB
+- `capture.actions()` - Iterator over processed actions (clicks, drags, typing)
+- `action.screenshot` - PIL Image at time of action (extracted from video)
+- `action.x`, `action.y`, `action.dx`, `action.dy`, `action.button`, `action.text`
+
+### Storage
+SQLAlchemy-based per-capture databases:
+- Each capture gets its own `recording.db` in the capture directory
+- Models: Recording, ActionEvent, Screenshot, WindowEvent, PerformanceStat, MemoryStat
+- Writer processes get their own sessions via `get_session_for_path(db_path)`
 
 ### Event Types
-- Raw: `mouse.move`, `mouse.down`, `mouse.up`, `key.down`, `key.up`, `screen.frame`, `audio.chunk`
-- Processed: `click`, `double_click`, `drag`, `scroll`, `type`
+- Raw: `mouse.move`, `mouse.down`, `mouse.up`, `mouse.scroll`, `key.down`, `key.up`
+- Processed: `mouse.singleclick`, `mouse.doubleclick`, `mouse.drag`, `mouse.scroll`, `key.type`
 
 ## Testing
 
 ```bash
-uv run pytest tests/ -v
+# Fast tests (unit + integration, no recording)
+uv run pytest tests/ -v --ignore=tests/test_browser_bridge.py -m "not slow"
+
+# Slow tests (full recording pipeline with pynput synthetic input)
+uv run pytest tests/ -v -m slow
+
+# All tests
+uv run pytest tests/ -v --ignore=tests/test_browser_bridge.py
 ```

 ## Event Types
 
 **Raw events** (captured):
 - `mouse.move`, `mouse.down`, `mouse.up`, `mouse.scroll`
 - `key.down`, `key.up`
-- `screen.frame`, `audio.chunk`
 
 **Actions** (processed):
 - `mouse.singleclick`, `mouse.doubleclick`, `mouse.drag`
-- `key.type` (merged keystrokes → text)
+- `key.type` (merged keystrokes into text)
 
 ## Architecture
 
+The recorder uses a multi-process architecture copied from legacy OpenAdapt:
+
+- **Reader threads**: Capture mouse, keyboard, screen, and window events into a central queue
+- **Processor thread**: Routes events to type-specific write queues
+- **Writer processes**: Persist events to SQLAlchemy DB (one process per event type)
+- **Action-gated video**: Only encodes video frames when user actions occur

-## Frame Extraction Verification

+- Wall/CPU time and memory usage
+- Event counts and action types
+- Output file sizes
+- Memory usage plot (saved to capture directory)
