-# Worker Management
-
-Dynamic worker pool for node execution.
-
-## Components
-
-### WorkerPool
-
-Manages worker thread lifecycle.
-
-- `start/stop/wait()` - Control workers
-- `scale_up/down()` - Adjust pool size
-- `get_worker_count()` - Current count
-
-### WorkerFactory
-
-Creates workers with Flask context.
-
-- `create_worker()` - Build with dependencies
-- Preserves request context
-
-### DynamicScaler
-
-Determines scaling decisions.
-
-- `min/max_workers` - Pool bounds
-- `scale_up_threshold` - Queue trigger
-- `should_scale_up/down()` - Check conditions
-
-### ActivityTracker
-
-Tracks worker activity.
-
-- `track_activity(worker_id)` - Record activity
-- `get_idle_workers(threshold)` - Find idle
-- `get_active_count()` - Active count
-
-## Usage
-
-```python
-scaler = DynamicScaler(
-    min_workers=2,
-    max_workers=10,
-    scale_up_threshold=5
-)
-
-pool = WorkerPool(
-    ready_queue=ready_queue,
-    worker_factory=factory,
-    dynamic_scaler=scaler
-)
-
-pool.start()
-
-# Scale based on load
-if scaler.should_scale_up(queue_size, active):
-    pool.scale_up()
-
-pool.stop()
-```
-
-## Scaling Strategy
-
-**Scale Up**: Queue size > threshold AND workers < max
-**Scale Down**: Idle workers exist AND workers > min
-
-## Parameters
-
-- `min_workers` - Minimum pool size
-- `max_workers` - Maximum pool size
-- `scale_up_threshold` - Queue trigger
-- `scale_down_threshold` - Idle seconds
-
-## Flask Context
-
-WorkerFactory preserves request context across threads:
-
-```python
-context_vars = {"request_id": request.id}
-# Workers receive same context
-```
