The discipline of building wrapper code, validation boundary checks, prompt routing, and error-handling scaffolds around unpredictable machine learning models to keep them stable and secure.

A favorite term among MLOps consultancies to make writing software wrapper code and error handlers sound like breaking wild horses or erecting industrial skyscraper scaffolding.

• Industrial Posture: Framing basic software error-handling loops as high-level safety engineering.
• Model Unreliability Mask: Dressing up the tedious work of patching model hallucination bugs in prestigious architectural terminology.
• House-Cleaning Reality Check: Like putting training wheels on a bicycle and calling it "structural mobility harness engineering."

The Martian (2010s) scene where NASA engineers build custom physical harnesses, airlock seals, and external support structures to strap a dangerous makeshift rocket onto a launchpad.

Building software wrappers and verification rules to control and correct model behavior.

“Investing in harness engineering prevents downstream system failures caused by model drift.”

“We wrote a python wrapper around the chatbot API to block invalid outputs before they reach the user interface.”
