render3d: ground_fill_golden.json is valid JSON (the cover and solid blocks each closed one brace too many)
...
gg_cover_json and gg_solid_json ended in plain strings with "}}", which only a template literal reads as one
brace: the cover's closed the top-level object before "solid", and the solid's left a stray "}" at the end.
The committed golden is fixed by hand to what the generator now writes.
ground_fill_test also checks the golden as JSON: one value with nothing after it (Json.parse reads the
first value and ignores the rest, so it alone would not have caught this), an object, its eleven sections
in order. The generator notes what the studio asked: past the density patch an empty tile reads 0 for R and
G (only past the map's edge does a texel clamp), and several clearings multiply.

render3d: ground_fill's conformance test and the generator of its golden
...
tests/ground_fill_test.ludic compares gg_json (gf_hash over fixed inputs, Math.lerp cases whose order
matters, the yaw as model.vert turns by it, a hand-written density, one cover chunk with a clearing and
one solid chunk) line for line with tests/ground_fill_golden.json, and checks ground_fill draws exactly
the candidates and a solid layer's far bands a subset of band 0. The golden is written by
tests/gen/ground_fill_golden.ludic, run from the repository root; it is not committed here.

tiles_open_test: "nothing on a device" asks what terrain_from_baked would have made - the coarse height and normal textures and the page pool - not gvk_frame_no, whose default is 1 (env.ludic), not 0: the open path ticks no frame

render3d: terrain_tiles_open_file(path, key, version, half, ox, oz) - a map's baked tiles opened for the CPU questions alone (terrain_height, _file, _smooth, terrain_ortho), with no device and no renderer booted: terrain_from_baked's opening without its coarse level on the GPU. False and nothing changed for another bake's key or version, a missing file, or a whole copy already kept (it answers first). tests/tiles_open_test: a bake written with LBAK's header answers its heights and photograph at a map origin of (300, -120), nothing on a device; the refusals leave no file open, and a bake opened after them answers. The hand-written tiles move to tests/fakes/tiles_file.ludic (payload, raw file, bake, the expected answer at an origin, the cache's snapshot), shared with height_file_test

render3d: the terrain's questions never page - ter_h and ter_o read a resident tile in place and any other through the file scratch (heights and now the photograph, four tiles each, sized when the tiles open, forgotten when they close), so terrain_height, _smooth, terrain_ortho, the chunk heightfields, ground_fill, grass, water and shadow no longer take slots or move the clock. Only the loaders page: tp_fill reads through tt_h_load / tt_n_load / tt_o_load, and terrain_tiles_prefetch as before. terrain_height_file is now terrain_height, kept as the name callers wrote against. No answer changes: every read was already the whole copy's texel. tests/height_file_test: heights and photograph equal the texels written, resident or not; a whole-map sweep of the questions, and a ground layer's fill over the map (a one-layer LGD2 written in the test), leave the slots, their contents, the clock and the read counts unchanged

render3d: terrain_height_file - terrain_height's exact bilinear that never pages: a resident tile is read in place, any other from tt_file into four tiles of scratch of its own (in the state's defaults, forgotten when the file closes), so no slot is taken and no recency bumped - a sweep at boot no longer changes which tiles the cache holds, and so what is drawn from it. With the whole copy it is terrain_height. tests/height_file_test: equal to terrain_height over a grid across many tiles, resident and not, at tile corners and past the edge; a whole-map sweep leaves slot_of, tile_in, ref, the heights, the hand and the read counts unchanged

render3d: a renderer that cannot draw says so and stops - LUDIC_HOME's leading ~ expanded (an unexpanded one left a run without shaders, logging 27 missing variants and drawing on), the SPIR-V manifest ends with E <count> and a cut or miscounted one is refused, and every such failure is a fault: r3d_open / r3d_load_step fail on it, r3d_fault() / r3d_fault_exit(code) for the game; tests/manifest_test
