Summary

Implement PipelineIntrospectionSource - a DataSource that renders live ASCII visualization of the pipeline DAG with real-time metrics.

Why

Developers need to visualize pipeline structure and performance during development and debugging.

Implementation

  • engine/data_sources/pipeline_introspection.py already exists
  • Renders: Stage DAG, signal flow connections, per-stage execution times, sparkline of frame times, stage breakdown bars
  • Can be used as any other DataSource in the pipeline

Status

Part of Epic #20
