- the test runner re-makes every state between tests again: since 12fdc07 a state is made by its getter on
first use, so re-running L_init_globals left the last test's state in place (state/tested failed its
second test); @L_reset_states forgets every lazy state, and the runner calls it before each test
- diag_json_case counts errors, and an absent @Ref / @Tint / @OneOf target is a warning since d82dc31:
ref_unknown is 1 error and node_bad 8
- schema_hash.ludic prints 1: a bool is 1 or 0 as text (random_plain's 1 1 1)
- permap_check_case looks for the unit warning without the quotes the JSON escapes
- baked_test's inputs-hash test makes its directory: each test has a temp directory of its own
- ludic deps prints phase 25's five counters too

examples/lang/permap (two maps, a chunked table with a negative, a positive and a
missing chunk, constants and fn by name, a nested list, a cross-row @Ref, a reload
shrinking in place, a bad file's file:line:col; built under arena strict with an @On
frame root), --check fixtures for a wrong field, a wrong type, an unknown constant and
a dangling cross-row @Ref, @Ref(PerMap) on an int, as PREFIX, and a @Unit warning.

- @PerMap registry R of T from "file.lres" reads <maps root>/<map>/file.lres at run time
(package.ludic's new `maps` line, default assets/maps); @Chunked(n) one file per chunk,
{cx}/{cz} in its name. No as PREFIX, no constants, no def, never open.
- permap_gen: state R, r_load/_clear/_find/_path; chunked: RChunk, r_in/_out/_slot/_find/
_clear/_path; a typed reset and fill per record over lres.ludic, rows, lists and list
records pooled per table / chunk slot, @alloc_ok on what grows at high water.
- permap_consts: lres_consts__(), the program's int and float constants by name.
- permap_check: ludicc --check reads every map directory (fields, types, constants, fn,
@OneOf/@Range/@Ref, cross-row @Ref keys in the same map, a key twice); --no-maps skips.
- @Ref(PerMapTable) is refused on a non-string field; the schema says scope/chunk per
registry and scope map on such a Ref, and lists the canonical @Unit spellings; any other
@Unit spelling is a warning naming the canonical one.
- reseeded (mac + win seeds; bootstrap-cfree out.ll == seed.ll).

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.

--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.

Most of a build was one clang -O2 on one .ll (the game: 32 s of a 41 s headless build, one core).
Both paths that assemble - the CLI's (build.ludic: ludicc --emit-llvm, then clang) and ludicc's own
(-o, which ludic bundle and the examples use) - now cut the program's IR into N parts with llvm-split
(externalizing what the parts share), compile them with one clang each in parallel (-x ir -O<opt>
-mmacosx-version-min=11.0, the link's own clang taking the objects where it took the .ll), and remove
the parts and objects after. N is $LUDIC_JOBS, else min(cores, free GB / 1.5).
It needs an llvm-split and a clang of the same LLVM (Homebrew's LLVM 22 writes attributes Apple's
clang 17 cannot read): $LUDIC_LLVM, else /opt/homebrew/opt/llvm/bin. With either missing, on Windows
(its shell cannot run the parts at once yet), with LUDIC_SPLIT=0, or when a part fails, it compiles the
.ll whole as before.
$LUDIC_OPT=1 is a developer's faster build; ludic bundle sets LUDIC_OPT=2 for its compile whatever the
shell says.
Measured before the compile-only rule (this Mac, 12 cores, one build at a time):
- the game headless: 37-41 s -> 13-15.5 s (8 parts / by free memory), peak 2.1 GB -> 1.0-1.1 GB;
- the lab headless: 43.1 s -> 12.7 s, peak 2.4 GB -> 1.0 GB;
- the game at LUDIC_OPT=1, split: 11.8 s (fps cost not measured).
Both built and linked clean; the goldens and a headless shot of the result are not run here.

A switch a library reads only as a process starts - libmalloc's MallocLargeCache, which on a game
keeps ~200-300 MB of freed load buffers - has to be in the environment before main. For a .app started
from Finder, the Dock or `open` that is Info.plist's LSEnvironment; `app env` is repeatable and each
K=V becomes a string in it. bundle_case's probe app carries one and checks it with plutil.

- The arrows, a press on the select and the pad step past a disabled option (ct_opt_step), wrapping
as before.
- A value naming a disabled option is shown as the nearest enabled one (the lower of two as near) and
set to it once the build is done: an event fired while the tree is built is cleared with the frame's,
so the clamp is queued (ct_clamp_n / _i) and fired after nt_fired_clear.
- The < or > whose next option is disabled is drawn disabled (its part's :disabled), so a cycler shows
where the options stop being on; it still steps past them.
- ct_build_select moves to controls_opts.ludic with the rest (controls_build.ludic 119 -> 104 lines).
Golden ui_select_disabled: options 3 and 4 disabled, a value of 4 clamps to 2, > is drawn disabled
there, > wraps to 0 and < from 0 steps back to 2. The 38 ui examples pass.

Master's windowed fog profile failed the fence at walk t 35 s: +512 B from value_new / value_put /
value_slot / value_lists under bd_class and cmp_keycap_model - a KeyCap first shown mid-walk.
It is a first build, bounded, not a per-show leak: an unmounted instance goes to in_free and the next
show of its class reuses it (in_reuse, `renew`), its props and model objects kept and filled in place.
Only a NEW instance makes them - bounded by how many of that class are up at once, and the ones
unmounted less than two builds ago. in_reuse already declared the record; the props and model objects
and their first fill, made afterwards in bd_class, were not. They are now: in_reuse marks a new record
`fresh`, and bd_class's first fill of it goes through bd_first_fill (@alloc_ok) - a reused instance's
fill stays judged, so a real per-show leak would still fail.
Golden ui_first_show: a component first shown at frame 700, once the fence is judging, then hidden and
shown twice more: bad 0 (the toolchain before this fails frame 701: +464 B value_new from value_slot
under cmp_cell_model, value_put grow - the profile's failure). The 37 ui examples pass.

Maroon Lake's launcher watcher - a process that only spawns the game and waits - held 58 MB, 48 MB of
it MALLOC_SMALL. Measured with malloc stack logging it was not the state defaults but L_grow: every
program sized every property type's per-entity store to MAX_ENT (1024) slots at start, 1,583 stores,
entities or none. And every state record was made with its defaults in L_init_globals before Boot.
- emit_lazy.ludic: a program's (not the runtime's) state global is left out of L_init_globals, and
every read of it calls @S_<global>(), which makes it on first call from its own initializer - after
every registry and plain global, so a default may read them (the init-order crash cannot come back
through a state). What a getter makes is declared (@lp_fdecl): a state first touched in play is made
once and not judged as a frame's keep. A function value's trampoline calls the getter too.
- L_grow starts the stores at ECS_FIRST (8) and doubles as entities come, as it always did past MAX_ENT.
The watcher (with the game's watch step moved before the systems' defs): 57 MB -> 11 MB; the only
state it makes is UiState (14 KB). What is left: AppKit's window, opened by rt_init before main for any
windowed program (~4 MB), and the runtime's font, image and 2D inits (~1.2 MB).
Goldens: the arena, fence, value and json goldens; the 36 ui examples; 30 of the 32 ECS test cases
(sprite_render and sprite_atlas time out under a plain runner with the toolchain before this too).
Package tests: ludic.base, save, settings, i18n.

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.

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.

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.

A block took whatever @lp_site held when it was made. Only malloc, calloc, realloc, concat, the number
texts, the float text, a substring and Text.* set one, so every other runtime helper - intern,
Text.repeat and the string builders, the Fs, Os, unicode, uuid and crypto helpers - was charged to
whichever line had allocated last (walk 9 blamed gvk_tex_storage, m4_new, kept_push$int and
survey_op_reward for intern's 16 B copies).
- Any `call ptr @lp_*` now takes a site of its own, its kind the callee's name when no better one is
known (intern, str_repeat, fs_list, ...). What the helper makes, in however many blocks and
through whichever helpers it calls in turn, is that line's.
- When the call returns, @lp_site goes back to site 0, now named "(runtime) (no site) unsited": a
block made with no site of its own says so instead of borrowing the last one.
- The ECS stores' grows and a mod's registered stores - the only allocations emitted outside
emit_bind - take a site each.
Golden alloc_fence_sites: two lines take turns keeping memory, Text.repeat and a record, every frame
judged. Each report names its own line (25 x +32 B str_repeat at :11, 25 x +16 B new Box at :12);
the toolchain before this charges 23 of the 32 B texts to the new Box line. The other fence and arena
goldens are unchanged; ludic.base's tests pass; the game's frame ratchets are 0 on main 7cb2b164.

Two blind spots from the windowed walk, where the heap grew about 1 MB a minute and the census read
`frames 0 bad 0 kept 0`:
- @alloc_ok memory was never held to its reason. Every R3D_ALLOC_DWIN judged frames (600) each site's
declared bytes are set against their high-water mark: a new high adds to a streak, a flat window
takes one off, a fall ends it. R3D_ALLOC_DRISE (6) is "declared but unbounded", said once per site
with its line; fail mode exits 86. The census adds `unbounded N` and a `dsite` row per declared
site by its growth since judging began. A list pushed forever grows by doubling, rising too seldom
to make a streak; a record or text made every time (a re-mount's defaults) is what it catches.
- Mem.play() (every screen opened) restarted the warm-up, so memory kept every frame was never flat,
the cap never came, and nothing was ever judged. A rewarm now keeps the first deadline, and past it
has R3D_ALLOC_REWARM frames (120) of grace.
Goldens: alloc_fence_unbounded (a record a frame under @alloc_ok: exit 86, named, census unbounded 1);
alloc_fence_rewarm (kept every frame, Mem.play() every 360: judged and failed at frame 3000 - the
toolchain before this runs all 6000 frames and exits 0). alloc_fence_leak, _declared, _auto,
alloc_ok_private and the four arena goldens unchanged; the game's frame ratchets 0.

render3d's stream_new holds its pool through a local (`let live = s.chunks; push(live, new
Chunk)`): the flow edge from s.chunks to live carried ESC to nothing, the Chunk records were
LOCAL, and the arena reset them under the stream - the row and horse scenarios' crash at
0xdddd... in fn_stream_update. An ESC class is now HEAP too, so every alias of kept memory is,
and a value stored through it is kept. Bidirectional alias edges were tried first and over-kept
through returns (el_place, rim).
- examples/lang/arena_alias.ludic: the stream_new shape; poisoned it read 3 3000, now 3 1518
- examples/modules/alloc_ok_private.ludic: @alloc_ok on a module's private function and on a
statement in its private generic, declared at run time (it already passes: a guard)
- the game: frame_allocs, frame_keeps, owned_leaks 0; the lab builds under `arena strict`; the row
scenario poisoned (R3D_ARENA_CHECK=1, 2400 frames) runs clean, bad 0 kept 0

Two more holes of the arena's family, found from ECS's births:
- a function called through a function value (UiClass.make's cmp_x_new, a step list, a System's tick)
has its result flow nowhere the analysis can see, so what it returned looked LOCAL - and a caller
keeping it (ludic.ui's instance table) would keep scratch. Every function taken as a value (fn f)
now has its result kept.
- an entry block has no name, and the analysis only walked named declarations: what an entry stored
was never seen. It is walked now.
examples/lang/arena_fnval.ludic (a factory in a field, its records kept by a pool across frames)
crashed poisoned before and prints '5 1053' as the heap does now; in ludic-dev test. Maroon Lake:
component constructors are kept, not births (birth_leaks 115 -> 103); what fn values return is kept
(frame_allocs 194 -> 210, frame_keeps 151 -> 162); 5293 sites local, 6586 kept.
