# Microgram: signal-theory-conservation-check

`station__algovigilance__microgram-signal-theory-conservation-check` · native (always callable) · domain `algovigilance` · pv-relevance `pv-core`

Verify conservation laws (L1-L4) on a decision matrix. Checks total count conservation and information conservation (d-prime bounds).
