A prebuilt tool, bin/ludic-ui-preview (built by ludic-dev build, shipped beside ludic-lsp, run as
`ludic ui-preview [--font DIR]`): ludic.ui with a backend that records every draw call as a line,
and mock component classes the studio describes (load / model / calls). frame t runs ui_show at
interface time t; text is measured on the CPU with the game's font.json metrics; locale goes
through ludic.i18n; tree / box / rules inspect the frame. No game code, no GPU, no network. The wire
protocol is frozen as tools/ui-preview/protocol-v1.md; smoke.txt is a transcript to run.
ludic.ui gains, all additive: UiClass.make_of, UiBackend.said / emitted, UiRule.text / at (with
comment line breaks kept so rule lines count true, and a class's styles read under its .lss path),
and ui_root, ui_find, ui_rules_of, ui_rule_value, ui_building, ui_class, ui_class_load,
ui_file_forget, ui_errors_clear; ui_nine_cuts_into exported.

Each UI component: module, place, doc, xml and lss paths, props and state
(type, default as written, place, doc), states_read (the header's states),
derived fields with their types, functions and events as the template calls
them (states and instance stripped), and the native tags its template uses.
natives: every ui_native / ui_native_input call with a literal tag - tag, via,
handler, place. schema_version stays 1; the lists are additions.

impostor_from_baked / impostor_refill read a bundle of two DX10 .dds (albedo, normal: BC7_UNORM, every
level) through tex_load_dds_at and gpu_tex_compressed - no gpu_tex_mips - and check each is the
impostor's size; sampled as a painted atlas is (clamped, no anisotropy). No BC on the GPU, or a bake
that does not fit, and the caller paints RGBA8 and makes mips as before; the fog re-open reads the BC7
file again. The handles and every draw are unchanged. Compile-only: nothing run.

GrassKind (grass_kind.ludic) carries what grass.ludic, grass_gpu.ludic, grass.vert, grass_cull.comp and
model.frag's BLADE path held as constants: the cell, s0 / d0 / radius, the row bands and rows, the blade
profile (neck, root, swell, tip, bend), the heights, clumps, widths and arch, where it grows (slope, snow,
the photograph's test), the root / tip / gone-to-seed colours, the far tufts, the root occlusion, the
roughness, the sheen and the wind. Its defaults are those constants exactly, so a game that sets nothing
draws as before. The shaders read them as u_gk_* (the cull as five more Params vec4s, 288 bytes);
grass_reset.comp writes each band's index count so a kind of other rows reaches the draw in order.
grass_quality holds the kind to a settings tier (never denser, never farther); R3D_GRASS_* still win.
grass_profile_w / _bend are the one profile, for the meshes and a game's preview. grass.mesh takes only
the cell: the rest of it is an older copy that already differs from grass.vert, left as it draws.

ludic.lab: lab_png_write / lab_png_write_from (raw 8-bit, 1-4 channels, stored deflate) in png_write.ludic,
importable alone with its own LabPngState; png_convert.ludic's previews of float textures (R32F min..max,
RG16F x255, HDR x/(1+x) + sRGB); lab_ppm_to_png on the same encoder.
render3d: bake_load.ludic - impostor_from_baked / impostor_source / impostor_refill (a fog re-open reads
the bake), sky_baked_in and sky_precompute trying the bake at the start yaw (sky_compute is the
convolution, and sky_ibl_bytes always uses it), carpet_from_baked / carpet_bytes / carpet_finish,
bake_part_count / _len / _off. Compile-only: nothing run.

A package on ludic.base alone. DevlinkNet is the transport (a game binds Udp, the test a fake);
DevlinkWorld's members are the verbs, each defaulting to "not offered" (err unbound): ping, hello (with
Build.schema_hash as 16 hex digits), cam_get / cam_set / cam_release, goto, map_load, time, weather, shot,
pause / resume / step. One request a frame, parsed in place from a fixed 8 KB buffer and answered into
another; map_load, shot and step answer later by id, one at a time, 5 s at most. Loopback senders only,
opened only when enabled() (dev_tools), co-op refuses everything but ping and hello. tests/devlink_test:
each answer byte for byte, bad arguments, a stranger dropped, co-op, the late answers and their timeout,
a closed build that never opens. Compiles; not run (the Master runs the package tests).

gltf_factors reads pbrMetallicRoughness.baseColorFactor, metallicFactor, roughnessFactor and the
emissiveFactor into the primitive (pr.fac), and prim_factors hands them to every program that draws its
textures (actors, the scatter's meshes and levels, the impostor bake) as 1 - factor, so a program never
given them - or a material that gives none (pr.fac null) - multiplies by 1 and draws as before. An
untextured material with a colour (or a metal/roughness) samples a pure white for it, so the factor is
exactly what it draws: horse_cornea is its own colour, not the 200 grey every untextured part had.

Both constants were worked out by hand and a byte off each: the tiles' bake wrote "LAAK" and "LDT2", which
ludic bake --check refuses, and r3d_baked_read, holding the same wrong constant, would have refused
ludic.base's correct files (the sun's shadow among them) while accepting its own. Now 0x4B41424C and
0x3254544C, checked against the strings; the unused LTT1 constant is gone. A re-bake is needed.

--emit-schema FILE writes the compiler's resolved view once the program type-checks: every
record (fields, types, defaults as written, docs, places, attributes), every registry with its
entries in their final order after the open-registry merge (key, constant, index, file:line:col
of the entry and of each field value, and which file contributed which keys), every const, and
the zero-argument functions a fn value can name. Deterministic, schema_version 1; the runtime is
left out. `ludic schema [file] [-o FILE]` wraps it.
--check --diagnostics=json prints every error as one JSON array on stdout: the checker's and the
module rules' all, a parse or lowering error as the last. Tokens and nodes now carry a column.
Fields take several @attributes; @Ref(Registry), @OneOf(PREFIX_), @Range(lo, hi), @Unit("..."),
@Asset("..."), @Color on a field and @AppendOnly / @ByKey on a registry change nothing but go into
the schema, and @Ref naming no registry is an error (every one reported). Fixtures:
examples/lang/attributes.ludic, examples/rejected/ref_unknown.ludic, cases in ludic-dev test.

A world swap unmounts the old map pack before terrain_reload, and the tiles' file (a baked file in that
pack) stayed open until terrain_unload. terrain_tiles_close closes it and stops the page pool; the next
map's terrain_from_baked / terrain_reload opens its own and makes the pool again.

The game names the tiles' and the shadow's bake files (key, version) before the map is made; r3d_init's
terrain step and terrain_reload then open them with terrain_from_baked / terrain_shadow_from_bytes and
generate nothing, and fall back to the survey (saying so once) when a bake is missing or stale. Without
the call nothing changes.

The tiles' photograph side is 0 when the map has none: no photograph or coarse photograph sections, no
decode, ter_o answers 0, and no coarse photograph texture - as such a map has always drawn. The cut and
terrain_tiles_bake no longer require one.

baked_open refuses a header whose key is not followed by a zero byte; a key a multiple of 8 long got
none. Now the payload starts at 32 + ((len(key) + 1 + 7) / 8) * 8, as bake_write writes it.

stream_capture(s, cx, cz, band) points the stream at a chunk of its own (made on the first capture),
calls the registered r3d_stream_fill for that cell and band, and returns how many instances it
emitted; stream_captured(i, k) reads them from stream_scratch. Build-time only; nothing in a frame
calls it.
