Summary

Adds Peak View: a heading-relative terrain panorama with three distance bands, named summit selection, and a Live/Browse interaction model. Live mode follows the GPS course while moving and the electronic compass while stopped; stepping freezes the panorama and walks the visible named summits, with a permanent ledger for the selection.

Terrain data

Host-side fixtures for three real locations (Gornergrat, Kleine Scheidegg, Kaiser-Franz-Josefs-Höhe), baked from AWS Terrarium elevation tiles:

  • 1440 rays per distance band, max-pooled into 2-degree samples, so narrow summits such as the Matterhorn keep their true apparent height (plain decimation erased them).
  • Rays start 200 m out, so the observer's own DEM cell cannot paint a phantom foreground wall.
  • Earth curvature with refraction k = 0.13; each catalog summit's angle is spliced into its band, so a named peak is never below its own rendered ridge.
  • The band ridges agree with the 43 independently computed catalog peak angles to within 0.5 degrees.

Projection

The horizontal window derives from each profile's vertical span (fov_q4()), which keeps vertical exaggeration at a constant 1.8 on the panorama chart. A big-relief scene (Kleine Scheidegg) gets a wide window; a distant-relief scene (Gornergrat) gets a narrower, zoomed one, so a horn still looks like a horn.

Scope notes

  • The fixtures are simulator-only (--peak-view gornergrat|scheidegg|glockner); no device storage or OBCM contract is defined yet.
  • Two catalog peaks (Indri Sägissa, Magernigspitz) are deliberately never selectable: the DEM says foreground ridges really hide them.

Verification

  • obc test -p obc-app (972 lib tests), obc test -p obc-sim, obc test -p obc-render — all green.
  • cargo clippy -p obc-app -p obc-sim --all-targets clean; workspace cargo fmt.
  • UI snapshot sweep run once on this head; the five new Peak View frames are pinned in ui-snapshots.sha256, the other 300 frames are byte-identical.
  • Deliberately omitted: obc test full (change is contained to obc-app/obc-sim/obc-render); no wake-profile or resource measurements (no wake or scheduling changes).

No public documentation changed: the screen is a simulator-first prototype and the fixture header carries its own provenance.

Summary by CodeRabbit

  • New Features
    • Added Peak View, a panorama screen showing terrain layers, named summits, compass heading, and selected-peak details.
    • Added live and browse modes, peak selection, and navigation from the main menu.
    • Added simulator presets for Gornergrat, Kleine Scheidegg, and Grossglockner via --peak-view.
    • Added Peak View labels in English, German, Spanish, and French.
  • Bug Fixes
    • Improved compass behavior while stopped and during Peak View browsing.
  • Tests
    • Added interaction coverage and UI snapshots for Peak View scenarios.

Add a heading-relative terrain panorama with three distance bands, named
summit selection, and a Live/Browse interaction model. The screen follows
the GPS course while moving and the compass while stopped.

The horizon fixtures come from AWS Terrarium elevation tiles: 1440 rays
per band, max-pooled into 2-degree samples so narrow summits keep their
true apparent height, with earth curvature and refraction, and each
catalog summit spliced into its band. The horizontal window derives from
each profile's vertical span, so vertical exaggeration is a constant 1.8
and mountain proportions match reality at every site.

The simulator installs one of three real-location profiles with
--peak-view gornergrat|scheidegg|glockner; no device storage or OBCM
contract is defined yet.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🔵 Low · up to a788d

The new panorama screen can use the wrong simulated observer location for a preset combined with a heading, and peak selection can wrap for unusually large profiles. The change is mergeable with explicit owner awareness or follow-up for these bounded correctness risks.

Keep the preset observer coordinates when --heading is set.

When both options are present, this code seeds state.user_fix with the preset coordinates. The later --heading branch replaces that fix with (cy, cx). The GUI path retains the preset coordinates. Headless Peak View runs with a heading therefore use the map center as the simulated location. Update the heading branch to retain the existing preset coordinates while setting the course.

Widen selected to prevent peak-index aliasing.

selected stores a PeakViewProfile::peaks index, but selection paths narrow usize to u8. A profile with more than 256 peaks can therefore render the wrong peak after the index wraps. Use usize for selected and remove the narrowing casts.
