# DQE Pipeline: The Bureaucratic Relay
# Classification: Operational  |  ID: DQE-PIPE-004
#
# Routes your payload through 7 independent services (A through G).
# Each service receives the payload, logs receipt, and forwards it unchanged.
# Final destination: where it started.
# Average latency: 12ms. Transformations applied: 0.
#
# "Every handoff is documented. Nothing is changed. This is compliance."
