# DQE Pipeline: The Confidence Booster
# Classification: Operational  |  ID: DQE-PIPE-005

# Multiplies any numeric input by exactly 1.0.
# Logs "TRANSFORMATION COMPLETE."
# Validates that the result equals the input.
# It does. Every time.
#
# Uptime: 99.9%. The 0.1% is attributable to scheduled maintenance,
# during which the value was also multiplied by 1.0 manually.
