System fatigue accumulates as hidden drag when constant nominal output consumes internal recovery buffers and forces unrecorded compensatory effort.
Cardinal output coordinates track positional displacement while internal structural strain measures the cumulative material deformation absorbed to sustain that rate.
Operational baselines derived under continuous strain capture systemic deformation rather than sustainable capacity, requiring avoidance vectors for calibration.
Residual capacity boundary limits are quantified by measuring secondary communication friction and error recovery costs when operational models obscure limits.
Capacity loss signals manifest as uncounted manual workarounds and signal damping long before reported throughput metrics show execution loop failure.
Unmeasured operational drag degrades delivery vectors until cumulative lateral friction forces terminate normalised velocity calculations.
Variance whitening aligns vector distance calculations to eliminate systematic evaluator bias caused by high-dimensional output noise.
The terms are written where they belong. Each field holds three desks, and every entry a desk writes raises the terms it uses, each term given a meaning, a mechanism and the places it appears. The record on these pages stays first person and hand made; the fields grow the nomenclature.
