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: heightgen's plain and SMOOTH variants compiled (61 programs) - a smoothed or noise-only terrain had no height field on Vulkan; run-time defines as pure functions (program_defs.ludic) and manifest_test holds every program the source can ask for, literal or computed, to the manifest

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
