Glossary

A working vocabulary for software factories. Dates mark when a term entered the current AI-development discourse, not necessarily its earliest use in computing.

01

A–Z

Back pressure
A control principle: autonomy must not exceed the capacity of the verification system that receives its output.
Comprehension debt
The growing gap between the software that exists and the software humans still understand. Popularized in 2026 factory discourse.
Dark factory
A pipeline that turns specifications into production software without human code review. Shapiro’s Level 5, January 2026.
Harness engineering
The discipline of designing context, tools, constraints, memory, feedback sensors, and control flow around coding agents. Böckeler / Thoughtworks, 2026.
Light factory
An agentic production pipeline with human judgment retained at selected approval gates, usually merge or release.
Ralph loop
A fresh-context iterative agent pattern: one task per run, filesystem as memory, repeat until the work queue is empty. Huntley, July 2025.
Satisfaction
StrongDM’s probabilistic framing: the share of observed trajectories likely to satisfy the user, rather than one boolean “tests pass.”
Verification debt
The accumulating cost and risk of AI-generated work that has not received credible independent verification. Associated with Werner Vogels, 2026.
