# Microgram: ab-coupling-imbalance

`station__algovigilance__microgram-ab-coupling-imbalance` · native (always callable) · domain `algovigilance` · pv-relevance `pv-core`

Antibody: detects action-reaction imbalance (stem-phys Couple trait). Input is pre-computed magnitude_delta = abs(action - reaction).

## Agent metadata

- `idempotent`: true
- `read_only`: true
- `expected_latency_ms`: unknown (not yet contract-tested)
- `cost_tokens_estimate`: unknown

## Input schema

- `magnitude_delta` *number* (required) — abs(action_magnitude - reaction_magnitude)
- `tolerance` *number* (required) — Input variable tolerance
