- Expand the transect to 1456 samples across 16 rows including the kerb/road/
sidewalk seam Ys (-1382/-1053/+718/+1047 and neighbours), X -20000..-2000.
Result: 0 holes, walk/reset/pause all PASS.
- Add a wall probe: find ground under each start, then trace 30 m horizontally
160 cm above it. A fixed Z 160 probe started inside the earth (street is at
Z ~366) and reported every row as a dist-0 blocker; grounding the probe fixed
it. Result: 0/35 blocking hits inside 21 m -> no invisible walls.
- GigLineShotActor: skip screenshot rounds under -qaselftest, else it quits the
game (bQuitWhenDone) before the transect phase runs.
Plan: extend qaselftest with (a) vertical transect rows at the road/kerb/
sidewalk seam boundaries, (b) horizontal walk-height probes to catch invisible
walls or blocking geometry in the street envelope, then run on the packaged
build and record evidence. Branch collision-seams-0.1.0.
