- SurfaceGuidance (core/sensors, pure, tested): the sole source of
bubble position, high-side direction, and ring scale. Bubble and
1/2/5-degree etched rings share one 5-degree visual range; the
clamped target puts a saturated bubble exactly at the rim ring.
- SurfaceBullseye: Compose Canvas glass vial with crosshairs and
amber bubble. Critically damped (no-overshoot) spring toward the
pre-clamped target; velocity carries across retargets. Reduced
motion (in-app pref or ANIMATOR_DURATION_SCALE == 0) snaps directly.
- Lock treatment: brief lime ring pulse on acquisition, persistent
lime tolerance label while locked, neutral numeric readout. Never
color-only; no full-screen lime state.
- Pipeline passes stable calibrated pitch/roll to the instrument;
deadbanded readout remains authoritative. Bullseye renders only in
the FACE_UP presentation.
53 tests passing.
