With one frame in flight, a buffer filled every frame (the interface's vertex
buffer, ov_vbo) was still being read by the frame on the GPU when the next
frame filled it, so gvk_buf_reserve released it and made a new VkBuffer and
its memory every frame - and every new buffer took a prime submit of its own.
Each handle now keeps a second buffer (gvk_bsp_*): a busy one swaps with it
when it is free, else the busy one becomes the second and one new buffer is
made; releasing a handle lets both go.
The launcher window (--launcher-ui, R3D_VK_PROF, per 120 frames): buffers
made/destroyed 120/120 -> 0/0, command buffers 240 -> 120 (one a frame). Its
footprint does not move with it (358 MB at 40 s, both): the churn was work,
not memory.

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).

gvk_swap_make freed none of what it made - the surface caps, the count, the
format and present-mode lists, the create info, the handle out - and replaced
gvk_swap_images without freeing it: a few hundred bytes every time the window
changed size, went to or from Retina, or the chain came back suboptimal. Each is
now freed on every way out (the minimised return and the failed create included),
and the old image list before the new one is made.
A windowed memory walk built against it (main 5ee600d2, 300 s, the autopilot
opening screens every 6 s): footprint 2816 MB at 120 s, 2818 MB at 300 s; the
fence judged 0 frames kept.

A load freed only the parsed trip's nodes (Json.free) and kept every string the parser made, because
a loader might keep one; free_all freed every string and every key, so on a tree a migration had
added a literal to (`Value.put(v, "sver", Value.str("2"))`) it freed the literal and aborted.
- The parser marks the string values it makes (JP_OWNED, in the node's otherwise unused num) and
interns object keys (a few names, never freed); free_all frees only marked strings, never keys,
and a list's spares too. A setter that gives a marked node other text (value_set_str/_strs,
value_into_str/_strs, value_become) frees the parser's text first. value_as_int / _as_float read a
string as 0 as before.
- ludic.base sv_str returns intern(...): every package load that keeps a text read from a section
(minimap labels, a Thing's look, photo tags and files, an effect's label, ...) holds its own copy.
Golden json_free_edited: parse, put a literal key and string in, set a string, keep an interned copy,
free_all - 1100 loads: the copy reads on and nothing grows (the toolchain before this aborts, 134).
Tests: ludic.save, base, settings, minimap, things, photo, effects; json_saves, value_list_regrow; the
36 ui examples.

gvk_sc_make's cache (program + bound textures -> a set in the kept pool) evicted
nothing until the pool's 8192 sets filled. A texture freed - a photograph's
thumbnail, a wall frame, any picture a screen loads - left its entries and their
sets behind for good, since its handle's generation moved on and the key could
never match again: 262 KB over 12 minutes of the user's play, and bound only by
the pool, hours away.
gvk_tex_release counts the releases (gvk_sc_dead); at GVK_SC_DEAD_MAX (256) the
next frame's start resets the kept pool and empties the cache (gvk_kpool_reset,
which waits for the frame in flight), and each draw still in use makes its set
again the first time it is drawn - the budget is the live combinations plus at
most 256 textures' dead ones. The declared reason on gvk_sc_make was the
swapchain's, copied; it now says what the cache is and what bounds it.

- ludic.ui cv_join (units_pieces.ludic:93): a var() value's pieces were joined by +, a text left
behind per piece on every memo miss; it is written at its length at once (units_join.ludic), and
the miss is its own declared function (cs_vars_miss), bounded by the memo.
- ludic.hints hn_slots (rail.ludic:41): hints_reset made a new rail every time; the rail is
emptied in place, made again only for another count (rail_slots.ludic).
- value_spare_put (value.ludic:138): a list's spares grow only past the most it has ever cut off;
declared as such.
- ludic.save: save_read reads, parses and frees the file's text - the tree's strings are the
parser's own - and says whether the text was whole (SaveRead.intact) for the words of a refusal.
Maroon Lake's trip and home reads kept the whole file on every load and every menu card read.
Tests: ludic.save (10), ludic.hints (8); the 36 ui examples; value_list_regrow, json_saves and
alloc_fence_declared unchanged.

The user's walk showed the footprint rising outside the Ludic heap. Jolt's bytes were already counted;
the navmesh's were not, so nothing could see them. Now:
- ludic.nav nav_heap_test: fifty crossings of a four-tile map by the resident index hold the tiles in and
the native bytes to the first crossing's; a thousand crowd walkers in and out grow nothing; a reset
gives back every byte the mesh took.
- ludic.physics cross_heap_test: a 1 km map of 64 m chunks kept to a ring round a player crossing
corner to corner and back, each chunk a heightfield, twelve owned posts and six owned scaled hulls
as the game makes them: six more crossings hold the bodies, the shapes and Jolt's bytes and peak
exactly. (A post made as an offset of a cylinder, with only the offset owned, leaked the cylinder
every time: the game's solid_pillar owns its cylinder directly.)
lib/macos-arm64 rebuilt; lib/windows-x64 needs native/build.sh run on the PC for the new exports.

From the user's play, reproduced on Maroon Lake's customisation screen with the pointer scripted over
each control (the lab's R3D_CLICKS): nothing on it was ever pressed or hovered.
- A screen's root <div> round a positioned panel (a component's root holding the kit Screen's
modal) lays out to 0x0, and the hit test (fr_pick) and :hover (fr_under) only walked into a child
whose box held the point - so nothing under it was reachable. A box with no size holds no point and
clips nothing: both look through it now (fr_empty), without hovering it.
- A control's parts (a select's < and >, a range's thumb) are made by ct_part, which never set
`hovered`: `select .ui-prev:hover` could not match anywhere. It is set as an element's is.
Golden ui_pointer_through: the panel's button pressed and hovered through the empty root, and a
select's > hovered (before this: pressed 0, hovered 0). The 36 ui examples pass.

The user's play of the bundle: the character shook while seated. chr_sit_tick eased the body onto the
seat point at the ground's height, then the same frame's chr_travel handed it to the walker, which
pushed it off a log, a bench or a boulder beside the seat; the next frame pulled it back. Unwalked, the
game's walker parks as it does under a rider. A hold's turn toward the work fought the seat's yaw the
same way. The new test sits the body against the boulder: 4.63 m from a seat at 5.7 before, still after.

Every tree on the map was drawn as an impostor card into all the cascades,
the near two included, whose receivers (within 60 m) are shaded by the near
trees' own LOD2 meshes cast beside them. The cards now cast from cascade 2 on.
Aspen view, same main and foundations, 240 frames, with the figure capsule:
shadow instances 323,587 -> 202,743; shadow GPU 4808-4942 -> 4579/4578 us;
median frame 17200-17693 -> 17178/17205 us. The look held: shots of the view
taken twice a side are identical within a side (0.00% of pixels past 8) and
differ by 0.04% across (every pairing).

In cascades 2 and out (receivers from 60 m) a skinned figure of more than
eight pieces - a dressed person, up to 86 of them - casts one capsule its own
height (radius 13% of it) instead of every visible piece: past 60 m nobody
can tell a garment's shadow from the body's. Animals (a piece or two), rigid
props and the near two cascades are unchanged. The capsule is made once.
Aspen view, same main (30ec1722) and foundations (15f1020), 240 frames, twice
a side: shadow draws 1889 -> 1799; shadow GPU 4808/4819 -> 4710/4714 us;
median frame 17200/17221 -> 16910/17128 us. Most of the far cascades' actor
draws turned out to be rigid props (the census's "skinned" counts draws, not
actors), so this is the smaller of the two.

From the user's play: clicking an item in the pack opened nothing, and the wardrobe's picks did
not respond - both are a component whose button says `emit click` (ItemCell, LookCell, ListRow),
answered by its user's on-click. An on-* attribute's name is kept as a browser would have it, so
on-click is on-press (tpl_event), and the emit looked for "click" and found nothing. An emitted
name now goes through the same tpl_event.
And a settings cycler's left arrow did the right one's job: any press let go on a select stepped it
forward. ct_activate_at steps back when it is let go over the select's .ui-prev; Enter and the rest
of the select still step forward.
Goldens ui_emit_click (the mouse and a press both reach on-click; with the toolchain before this,
neither does) and ui_select_arrows (1 -> 0 on <, then 2 on > >; before this, 1 -> 2 on <). The 33
ui examples pass.

From the fence's kept frames in 22 minutes of play:
- A component field that is a record or a list of records was `value_put(o, k, view_val_T(x))`,
a whole new tree every frame (HudPrompt's notifications). view_fill.ludic generates view_set_T /
view_set_list_T / view_fill_T that fill the object and list under the key in place.
- value_list_fit dropped the items it cut off and value_item made new ones as the list grew back,
a Value per item per regrowth (value_item / value_set_strs); the cut-off items are now the
list's spares (Val.spare), and an item of another kind is turned rather than replaced.
- ludic.ui: a scroll box's "scroll" and a slider's "change" fired a fresh Value.float a frame
(sc_walk, scroll.ludic:36); ui_fire_float takes one from a ring kept with the state (fired.ludic).
ui_object_fit_into is exported, for a draw that keeps its list.
- Json.read_file(path): read, parsed, and the file's text given back - Json.parse(Fs.read_text())
kept the whole file on every read (Maroon Lake's settings peeks).
Golden value_list_regrow: a list alternating 6 and 2 items every frame keeps nothing (the toolchain
before this fails it: +128 B new Val from value_item). Game compiles; ludic.i18n/settings/hints/
base tests pass (ludic.ui has none); arena and fence goldens unchanged.

settings_fill_json(v) writes every saved setting into an object the caller keeps, making a Value
only for a key seen the first time (value_set_str / value_set_int): Maroon Lake's Settings pages
rebuilt the whole tree on every change and dropped the old one. A text read from a file is interned,
and so is a muted card's key ludic.hints does not know, so the parsed tree can be let go whole.
Test: the store filled into a kept object changes its Values in place (6 tests pass).

i18n_use re-read and re-parsed the .po on every change of language (ev_SettingsChanged, SetLang)
and dropped the old tables for good: the play of 22 minutes left lines_of 650 KB, fs_read_text
409 KB, PoEntry 113 KB and unquote 273 KB unreachable, and three of its @alloc_ok sites were
declared but unbounded. Each language's tables are now filed by index once built (tables.ludic,
I18nTables) and put back by reference; a new probe (i18n_init) or a different file for a code
(lang_add) reads it again.
Test: a language switched back to is its kept tables, not its file read again; a new probe reads
it (9 tests pass).

The user saw kit grass, ferns and flowers lit up at night. Nothing was
emissive and every layer draw binds the scene's lighting; what differed was
occlusion. At night the sky's light is nearly all the light, and it is
scaled by ambient occlusion: the meadow's blades are heavily occluded near
the ground, while a kit plant's own AO map knows nothing of the grass around
it, so it took the full sky. By day the sun hides the difference.
model.vert hands on each vertex's height above the model's base (v_lh), and
a non-blade FOLIAGE plant under 2 m scales its AO from 0.35 at the ground to
1 at 0.9 m. Crowns and the blades are untouched.
Measured in the lab (R3D_AT=tree, same binary, old and new SPIR-V): the fern
against the meadow beside it was 2.05x at 23:00 and 1.66x at 13:00; now 1.58x
and 1.60x - the same relation by night as by day. The flowers' brightest
tenth at night 78 -> 52. The noon frame moves 8.4% of pixels past 8 (the fern
and flower bases a little darker; run-to-run noise is part of that).

The user's play found the aspens' branches swinging like rope. Three terms:
- the whole-tree bend reached 22% of the tree's height at a gust's top (three
metres on a 14 m aspen); 4.5% now, and the side-to-side part at a quarter of
that and slower;
- a branch term: nothing within 0.35 m of the trunk, growing with the distance
out, phased by the direction the branch leaves the trunk (constant along a
branch, so it moves as one piece and its neighbours are out of step);
- the aspen's leaf flutter took its phase from each vertex at eleven radians a
metre, which bent every twig along its length; about three now, and half the
amplitude.
Measured on the lab's `aspen` view (10-frame bursts, crowns only, same binary
with the old and new SPIR-V): pixels moving more than 8 over ten frames 16.8%
-> 9.7%, frame to frame 4.4% -> 2.1%. SPIR-V rebuilt with `ludic-dev shaders`
(vertex stages only; the manifest is unchanged).

Every read of the screen made bytes(screen_w * screen_h * 4) and dropped it:
the user's manual play left 22,970,368 B unreachable (exactly 3024x1898x4)
at gpu_vk_draw.ludic:1673 - one per photograph (shots' ph_grab, through
gpu_read_screen_bytes). The read-back is now gvk_read_px, made once and made
again (the old one freed) only when the screen's size changes.

water_reflection_pass made view(water_saved, 16, 16) and view(water_saved, 32, 16)
inside the block that makes the reflection target, so every time the target was
made again (a resize, a render scale, a settings change) two more 16-byte views
were made and the last two dropped: the windowed walk's fence caught one such
frame, +32 B. water_saved is the state's for good, so its views are made once.

AVFAudio keeps a 64-byte AudioQueueOwner for good on every AVAudioPlayer play
after the clip has finished - measured one a play, whatever is called around
it (prepareToPlay, pause, no rewind) and still there after the player is
released; a stop before the play made one every time. The windowed walk showed
it as AudioQueueOwner 73 -> 87 in a minute.
A sound is now decoded once into a PCM buffer and played by a voice of its own
on one shared engine: a player node (the buffer scheduled again on each play,
looping for -1), a varispeed (the rate) and a small mixer (volume and pan).
snd_playing compares the uptime clock with the end worked out when the clip was
played (asking the node where it is made two AVAudioTime objects a call), and
snd_play drains an autorelease pool of its own. The C interface is unchanged.
A harness driving snd_* directly (400 plays past the end, the playing flag
checked during and after each, a loop and a stop, the setters) holds the heap
flat to a block and gets the flag right 400 of 400; the windowed valley
compiles and links against it.
