# Microgram: maxsprt-gate

`station__algovigilance__microgram-maxsprt-gate` · native (always callable) · domain `algovigilance` · pv-relevance `pv-core`

MaxSPRT (maximized sequential probability ratio test) gate for sequential signal surveillance. Evaluates observed-to-expected ratio against critical value with look-limit enforcement.

## Agent metadata

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

## Input schema

- `observed_count` *number* — Number of observed adverse events
- `expected_count` *number* — Number of expected adverse events (baseline rate)
- `current_look` *number* — Current sequential analysis look number
- `max_looks` *number* — Maximum number of planned interim looks
- `critical_value` *number* — Observed-to-expected ratio threshold for signal detection (scaled x100, e.g. 300 = ratio of 3.0)
