strain · measurable-degradation
The degradation of output that occurs when a parameter is near the wall of its window, indicating how narrow the current range is compared to what the thing can persist within.
Examples
- The Fukushima nuclear reactors experienced fuel rod strain as cooling parameters approached safety wall limits before meltdown. engineering
- In 2008, Iceland's banking sector collapsed when leverage ratios drifted near the wall of capital adequacy range. economics
- E. coli growth in lab cultures shows metabolic strain when pH nears 4.5, the edge of its persistent range. biology
Emergence
through: The components interact to produce strain as a measurable degradation: when a parameter conditioned by a current drifts near the wall of its persistence window, the narrowness of the current range relative to the full range enables comparison that yields degradation.

| contrasts-with | narrow.spatial | strain increases as the active range nears a wall; narrow describes a permanently small window |
| medium-for | drift.aimless | drift can push a parameter into strain |
| contrasts-with | maintenance.upkeep | maintenance prevents strain; strain indicates failed maintenance |
