The visual gate had stopped measuring anything: 30 of 32 scenarios
failed, and the two that passed were the worst result of the lot.
Deleted the 15 top-down scenarios (fog, HUD, dialogue, NPC, minimap,
cursor) and their goldens. They all failed at a near-uniform ~12%, and
that uniformity across unrelated scenes is one global cause -- the
ultrawide UI stretch moved every element. They cover the renderer the
cascade freezes until Phase 5, which will need its own tests anyway, so
re-baselining would only have blessed a deprecated layer nobody is
reviewing. Jeroen's call.
The remaining problem was the goldens that PASSED. atlas_GJ338Bd_Block
and atlas_GJ445c-m1_Chunk matched at 0.0% because capture and golden
were both blank -- the same "goldens have been measuring nothing" trap
e024cfb3f caught at Global, still live at the bottom of the ladder. The
cause is that every below-Global golden descends at jump_to(ZERO), and
world-metre zero is merely the origin of the region grid, not anywhere
chosen. So _setup_atlas_golden_shot now takes an optional world_center
(default ZERO -- existing goldens are untouched), and a new
atlas_GJ820Bc_land_* set walks Region through Chunk at ONE land point,
so the rungs can be read as a descent instead of five unrelated frames.
aliveness_probe prints the placement's world metres alongside its pixel
and survey cell, since that is the coordinate the Atlas actually
navigates in.
Recorded because it will be asked again: the ladder is anchored via a
CityPlacement, but that is a match record -- a pixel, an archetype, an
orientation -- not built geography. No settlement exists anywhere yet
and none is due before T-1207, so the empty deep rungs are the expected
state. What the ladder judges is the nature layer.
