# Dataflow Architecture

> A convention of arranging processing as a graph of stages connected by explicit data edges, where a stage runs when its inputs arrive.

## Repair

- Refactored by: Make Data Edges Explicit, Split Stages
- Detected by: implicit shared state in pipeline
- Violated by: hidden data dependencies between stages
- Measured by: data dependency clarity
- Enforced by: pipeline contracts

## Requires
