The seat height, the horse's walk, gallop, acceleration and turn (VE_HORSE_*), its stamina (a gallop
over 6 m/s spends 6 a second, a walk gives back 3, 5 needed to gallop) and hay (0.02 a metre,
VEHICLE_HAY_MIN), the boat's stroke, turn and wind (VE_ROW, VE_ROW_TURN, VE_WIND) and where a rider
gets off (the horse's 1.2 m flank, the boat's 1.25 m wade) move into VehicleSpec (spec.ludic), held
per kind in VehiclesState.ve_specs and kept across a reset. vehicles_spec(kind, spec) sets one,
vehicle_spec(kind) asks it; a kind with no spec cannot be called. VEHICLE_HORSE and VEHICLE_BOAT stay
the kinds. The tests hand Maroon Lake's numbers in, and a new one holds a spec's walk and seat_h.

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).

--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.

baked_tex.ludic reads ludic.base's baked form by hand (render3d uses no package): the LBAK header, the
key ("png_sheets" / "cutouts", the Bakes rows) and the generator version, then the payload -
w, h, channels, depth and the samples for a PNG (the caller frees them as it would a decode), a whole
.dds for a cut-out (tex_load_dds_at: a .dds at an offset). Missing, or another key or version, and the
PNG path runs as before. Compiles with Maroon Lake (game, lab, lab/bake/textures).

ZInflate (z_inflate_new) holds the bit reader, the RFC tables and every table and scratch list a block
builds, rebuilt in place: an inflate allocates nothing, and a worker thread inflates in a context of its
own (made on the program's thread). z_inflate_in / z_uncompress_in / z_gunzip_in take it; z_inflate /
z_uncompress / z_gunzip and every caller (image, atlas, tiled, render3d's png_decode) are unchanged and
work in RtInflateState's one context. The old per-call lit/dist tables were also leaked on an error
return; there are none now. Compiles: Maroon Lake headless, examples/library/tiled_p2 and tiled_p6.

Within a pass a row writes only its own still-masked texels and reads only neighbours already let go,
which no row writes that pass, so the result is the single-threaded one. The worker takes a DilateJob
of plain buffers and allocates nothing. tex_dilate_bytes (safe_api) and examples/rendering/dilate.ludic,
which checks it against the old loop on RGB and RGBA atlases of sizes that do not divide (DILATE OK).

zones_set / zones_clear / zones_merge, zones_contains / zones_nearest and the clusters' bounding circles,
over fixed arrays of ZONES_MAX (16). WildlifeWorld.active freezes an animal outside (no state change, no
dice), NpcWorld.active a walker (and no birth outside), VehicleWorld.active a moored boat, and
ThingsWorld.restocks keeps a morning's restock inside; every default is "everywhere", so an unbound game
is unchanged. Tests: the merge (near players one cluster, far two, a player leaving splits a chain),
contains, nearest, the radius; wildlife, npc, vehicles and things pass as before.

Set before r3d_open: the frame's uniform ring is 2 x 4 MB (was 2 x 64), memory blocks are 8 MB with
anything over 4 MB on its own (was 64 and 16), and the descriptor pools are an eighth of a world's.
Maroon Lake's launcher window draws a picture and text and never becomes the game; its launcher home
and Settings page draw pixel-identical on it. The full-size path is unchanged (steady: STEADY OK).

Plan 25.1c: vk_mac.ll's @lvk_ac (posix_memalign under a 16-byte header of scope/offset/size, atomic
counters) passed at every render3d create/destroy (49 sites; the caps probe keeps its own null pair);
lvk_ac_bytes/_peak/_allocs/_scope_bytes for the fence, Vk.alloc_bytes. vk_win.ll: null and 0.
MoltenVK 1.4.2 counted 0 live bytes through them in steady. Fence findings: gvk_pipeline freed its 17
create infos (and reuses one bufs list); actor_init fills ac_spare with 512 records (actor_fresh,
m4_new, v3_new at first placement in play). Compiled, not run (the user's call).

The encoder appends into RtJsonState's buffer (grown only past the biggest document yet): ints and
Q16.16 fixeds written as digits in place, floats through string() and freed. Json.encode copies the
answer out once; Json.write_file hands the buffer to Fs.write_text (.tmp + rename) and keeps nothing.
json_saves.ludic: exact text, the file equals encode, parse round-trips, 1000 saves grow 0; clean
under MallocScribble. json_quote (the + builder) is gone.

Math.max, Math.sqrt and the rest (and the bare min/max/abs/clamp) are computed inline by the
emitter, and L4 gave each the unknown type, which agrees with everything: Maroon Lake's trail
put Math.max(5, n) into Notify's string field a1 and it failed in LLVM ("%t63 defined with type
i32 but expected ptr"). It was never about two dispatches on a line - one is enough. The checker
now mirrors the emitter: a float/double first argument gives that type (sign an int); otherwise
min/max/abs/clamp keep the first argument's type, sign/floor/ceil/round/posmod/wrap/ping_pong are
ints, the rest fixed. Named arguments or an argument it cannot type leave it unknown.
rejected/math_into_text is the case. Reseeded.

Found by reading every builtin (Os.platform's 8 KB per call started it). Log builds its line only at
or above the threshold and frees it; DateTime.format folds through + so its pieces go; Input.text
encodes into one buffer; Path/Mime/Fs/Os free their temporaries on every path; string results of
Text/Path/Mime/DateTime/Os dirs are fresh and Text frees a fresh argument. Reseeded.
runtime_temps.ludic: 19.8 MB -> 0 over 20,000 rounds, 64 KB -> 0 over 200 of file work; clean under
MallocScribble. string_temps still 0.

lp_os_platform and lp_os_arch malloc'd 8 KB per call (the uname buffer) and kept none of it:
string_temps now asks both every round, 327 MB over 20,000 before, 0 after. Reseeded. render3d:
MoltenVK made a mapped buffer's MTLBuffer at its first bind (fn_gvk_draw +4 blocks in the boat
window); gvk_buf_reserve queues it and the next frame's command buffer copies 4 bytes out of it.

stream_update made a Chunk and a words copy per new chunk (fn_stream_update +39 blocks / 13.2 KB a
window with the hiker in the drifting boat). The pool holds STREAM_MAX_CHUNKS records; the arena
is twice the layer's cap; eviction compacts it; a chunk that cannot be kept is gathered from the
scratch. stream_clear_all frees records, lists and streams. steady: 300 new cells, cap 256: 156 KB
before, 0 / -4.9 KB after, and every kept chunk's data checked against its cell.

The pools kept every command object ever recorded, so the heap grew each time a frame drew more than
any before (fn_gvk_draw under vkCmdBindVertexBuffers/BindIndexBuffer/Draw in the leakcheck; ~650 B a
draw). Off: 3.7 ms a frame either way over 520 actors. steady: 20 to 200 actors grows 5-7 KB with it
off and 120 KB with it on (bound 16 KB).

No bake and no new file: the skeleton comes from the skin's parents and rest pose (its own joints
and their ancestors - a kit holds several rigs), a clip from anim_read_doc's channels. Built by
native/build.sh from the pinned release; the Windows DLL imports KERNEL32 alone and passes there.

Vk.heap_bytes pulled the Vk module - and on lang/uifree the GL window path - into a plain program,
which then failed to link (_cgl_offscreen, lgl_GetError). Os.heap_bytes is malloc_zone_statistics

Json.free / Json.free_all.

gvk_tex_storage freed none of ici, out, req and vci (8 blocks a two-texture model); tex_load_ex kept
dds_path_of's string. Found with malloc_history over 400 load/release rounds (712 bytes a round, all
of it these). steady: the model's bound is 4 KB over 200 (was 1.6 MB), and the frame is the least of
three settled windows - a valley self-test beside it read 87 KB once.

s[a .. b] is always a copy, so it is freed once a +, a comparison or print has read it. Reseeded.
string_temps.ludic adds a slice compared and a slice concatenated each round (960 KB over 20,000
before, 0 after) and a kept slice read after its +.

The left half of a + chain, a template's pieces and holes, a number's text and a side made only to be
compared are marked fresh and freed after the +, ==, != or print that reads them. lp_int_str and
lp_long_str move their digits to the start of the buffer, so the pointer they return is the one
malloc gave. Reseeded. examples/lang/string_temps.ludic: kept intermediates stay good, and 20,000
rounds grow the heap 0 bytes (2.9 MB before).

A freed texture or buffer id goes on a spare list the next one takes; tex_note_size keeps sizes by id.
model_release frees prims, meshes, material names, the skin and leaves gltf_cached. actor_release
takes an actor off the stage and actor_new reuses its record (ECS's Things come and go all day).
steady.ludic: an actor round at 0 bytes over 2000.

n x n samples of chunk (i, j) of a size_m grid from the terrain's corner, row-major into the
caller's buffer with nothing allocated, each the (1 4 1) / 6 B-spline filter of the texels under it
(ter_spline_at): what ludic.physics' jph_shape_heightfield_bspline makes of the whole map, so a
chunk's physics ground matches the drawn one and its neighbours' to the bit. The read-back lives
for the whole map (terrain_generate to terrain_unload). examples/rendering/chunks.ludic, in the
suite, checks the shared edges, a sample against the filter by hand, and a short buffer refused.

gvk_mem_new made a one-slot []pointer per allocation, and turned the requirement's size and
alignment into strings to read them as ints; gvk_list_drop_last rebuilt the spare-record list to
drop its last entry; gvk_mem_id did the string round trip on every free. One slot is kept
(gvk_map_slot), int() truncates a long, the spare list pops. Every Text.to_int(string(x)) in
render3d is int(x) now.
Vk.heap_bytes() (vk_mac.ll: malloc_zone_statistics' size_in_use; 0 on Windows) and
examples/rendering/steady.ludic, in the suite: a buffer released and made again 5000 times and
600 whole frames gain 0 bytes each - the allocator before this, 1,120,000 over the 5000.
