# Microgram: perturbation-boundary-projector

`station__algovigilance__microgram-perturbation-boundary-projector` · native (always callable) · domain `algovigilance` · pv-relevance `pv-core`

Routes a perturbation pattern to the appropriate evaluation strategy based on boundary data availability. Implements the core architectural innovation: compute the interaction once, evaluate at any boundary. Exercises ∂ (Boundary) as a first-class parameterizable object.
