System‑Induced Depletion Leave (SIDL): A Structural Primitive in the SignalRupture Canon

System‑Induced Depletion Leave (SIDL) introduces a missing structural category in contemporary governance: the recognition that modern institutions generate predictable depletion through slow harm, exposure saturation, infrastructural decay, administrative coercion, and contradictory behavioral constraints. Traditional leave systems misclassify this harm as personal failure, framing exhaustion as an individual shortcoming rather than a systemic outcome. SIDL reframes depletion as a governance artifact and asserts that recovery is a structural obligation, not a discretionary benefit. By integrating Slow Harm Theory, Exposure Theory, Social Infrastructure Theory, Infrastructure Determinism, and the Eroded Subject, SIDL establishes a coherent diagnostic framework for understanding how systems exceed human capacity and then blame individuals for the resulting impairment. SIDL formalizes the insight that any sufficiently complex, high‑exposure, administratively saturated system will produce depletion regardless of individual resilience, making structural leave not optional but inevitable. This primitive provides institutions with a vocabulary for harms they already observe but cannot categorize, while exposing the extraction logic embedded in legacy leave architectures.
