- INAV D-term pre-diff LPF: upstream INAV firmware work for an optional
  pre-differentiation low-pass filter on D-term input, with the feature disabled
  by default while flight-test data is collected.

## Contribution Requests

The main contribution hub is https://19379353560.github.io/contribute.html.
The most useful feedback is hardware review, safe bench-test notes, anonymized
INAV Blackbox logs, and flight-test comparisons for `dterm_lpf2_hz`.
