A state where a software system, algorithm, or process has been tuned so narrowly for a specific metric or benchmark that it loses flexibility, degrades under real-world conditions, or breaks entirely when inputs change slightly.

Used by tech consultants and engineers as a humblebrag or protective excuse when a complex feature or model fails in production, implying the system was simply "too refined" for messy reality.

• Flawed Engineering Shield: Framing a brittle, fragile system that breaks under normal use as a masterwork of hyper-refinement.
• Metric Obsession: Prioritizing synthetic benchmark scores over real-world operational durability.
• Kitchen Reality Check: Like sharpening a knife blade so thin that it curls into a wire the moment it hits a cutting board.

Ford v Ferrari (2010s) scene where Ken Miles' experimental GT40 engine is tuned so aggressively for raw speed metrics that it literally melts and blows smoke on the test track.

Tuned so narrowly for specific tests that it breaks under normal real-world use.

“Our prompt pipeline became over-optimized during testing, leading to edge-case failures in production.”

“We tuned our search script so strictly for sample files that it crashed when real clients uploaded unformatted PDFs.”
