Section 2.4 sensitivity: semantic import hub for provider modules

Import hub collecting the proved semantic units (frozen definition and characterization files together with the public Section 2.4 A modules) needed by the Section 2.4 sensitivity provider modules.

Cycle-safety rule

Provider modules import this file, never Algsuperdiff.Section24.Sensitivity.Vocabulary. Vocabulary is imported by the frozen sensitivity anchors, so a provider importing it (directly or transitively) would create an import cycle when the anchors are onto their providers. Accordingly, this file must never import Vocabulary or any frozen sensitivity anchor (ResponseJDerivative, CoarseMatrixDerivativeBound, LambdaSensitivity, ResponseJSensitivity, BigLambdaSensitivity, BigLambdaSensitivityAtDelta, LambdaSensitivityUnconditional, ResponseJSensitivityUnconditional).
