Navara's 3D Tiles source defaults to model.height 1, which moves a
transformed tileset by a metre along Earth-fixed X: on the synthetic set
flat roofs read 0.12 m high and a sloping roof 0.68 m off, and the drawn
meshes move with them. The adapter sets the height to 0 and records the
package behaviour in WORKAROUNDS.md, with a test that loads the real
package. The downward surface ray now takes its direction from the
place's own normal, so it no longer drifts sideways.
qa-tiles-fixture gains --report (heights and drape pixels per engine,
without asserting), starts on Cesium, and checks each drape hidden, shown
and hidden again; qa-surface-heights uses the plan's 0.5 m tolerance under
tiles and names the point that misses.
qa-surface-heights loads deterministic fixtures for import pins,
infrastructure bases, ALPR markers, directions A/B, bikeshare stations
and Bhote Koshi story points, waits for the app to settle on each engine
and records every placed point through the mover contract. --compare
fails when a point moved by more than 0.1 m on terrain; --tiles checks
the points land on the synthetic tileset's 50 m block.
