# Sensitivity Analysis Guide

Use score-time sensitivity mode:

```bash
babappa score \
  --alignment-dir data/alignments \
  --tree data/tree.nwk \
  --bundle run/fit_null/null_bundle.json \
  --outdir run/score \
  --sensitivity \
  --sensitivity-bandwidths 0.10,0.15,0.20 \
  --sensitivity-kappas 1.5,2.0,2.5 \
  --sensitivity-replicates 299,999 \
  --sensitivity-energy-families gaussian,diagonal_gaussian \
  --sensitivity-codon-frequencies f3x4,uniform
```

Outputs:
- `sensitivity/sensitivity_summary.tsv`
- `sensitivity/sensitivity_stability.tsv`

Interpret unstable significance as a caution signal about null-model adequacy.
