# Microgram: preemptive-pv-trajectory

`station__algovigilance__microgram-preemptive-pv-trajectory` · native (always callable) · domain `algovigilance` · pv-relevance `pv-core`

Trajectory amplification: detect accelerating reporting trends using Hill curve amplification on time-series data. Reports slope, amplified slope, and whether the signal is accelerating.

## Agent metadata

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

## Input schema

- `data` *object* (required) — Array of {time, rate} data points (minimum 2)
- `n_hill` *number* — Hill coefficient for amplification (default 2.0)
