Multi-segment runs with Change Grade

Real jobs often need more than one grade — a 0.25% leg into a 0.10% leg, or a level pad that transitions into a slope. Manual Grade supports this through the Change Grade button in the sidebar.

To change grade mid-run:

1. Tap Change Grade in the sidebar. The controller halts (Manual mode only — the Excavator manual-grade sub-flow has no controller halt). The current segment is closed at your present position.
2. No dialog opens — the inline Set Grade bar (already visible once grading stops) holds the prior grade, direction, and depth offset.
3. Edit the values and tap Apply.
4. Drive to the new start point and lower the blade.
5. Tap Start. Because Change Grade closed the segment, the Ready to Start? dialog appears again — confirm to anchor the new segment's 0+00 at your current GPS, and the next segment begins.

Where the segments show up:

• Profile chart. The run draws as one continuous line on a cumulative-station axis. Each Change Grade reads as a kink in the design line. The current station resets implicitly at each segment, but the chart x-axis keeps growing so you can see the whole job.
• Map. Each segment's 0+00 anchor is marked with a colored pin and a labelled pill, for example "S1 · 0.50% ↓" or "S2 · 0.25% ↓". The colors cycle through orange, blue, purple, and pink as you add segments.
• Top stats bar. A Seg N/M chip appears when M ≥ 2 — N is the active segment, M is the total count for the job.

Where Change Grade is available:

The button appears in both the Manual Grade view and the Excavator manual-grade sub-flow (no design loaded), whenever grade parameters are set — including while grading is active. In the Excavator sub-flow the controller-halt step is a no-op (Excavator has no hydraulic commands).
