ludic-fmt --lint --json prints the violations --lint reports as one JSON array on stdout,
[{file, line, col, rule, message}] ordered by file, line and column (col where the rule knows it),
the summary on stderr, --lint's exit status, and never rewrites the baseline. ludic-fmt - refuses a
buffer that does not read as Ludic (a string/template/key literal left open, a bracket never closed
or closed by the wrong one) with exit 2 and name:line:col on stderr; - --lint judges a buffer as the
file --stdin-name names (--stdin-rel: that path relative to the project), against its baseline and
lint paths. ludic fmt --lint and ludic fmt - run it from the nearest package.ludic upwards (from
--stdin-name's directory when given). Hooks read nothing and write to stderr under --json or -.
Regression cases added to test-tools and ludic-dev test (fmt_editor_cases), not run.

stdin is read once, whole, and read_file serves a copy of it wherever the program opens <path> -
the entry, an import through a barrel, a component's .xml / .lss, an .lres. Paths match after
normalising both ('/' separators, relative under $PWD, . / .. / // folded, case on Windows);
diagnostics keep the file's usual name, with the buffer's lines and columns. A <path> nothing
opens is one warning. On ludic build it implies --check. Reseeded; bootstrap-cfree fixpoint holds.

`ludic syntax [--json] [-o FILE]` prints what `ludicc --emit-syntax` does (a line
per entry, or the JSON). `ludic-dev syntax` writes, between "ludic-dev syntax:
begin" / "end" lines, the keyword, type, phase and attribute tables of
ludic_syntax.h, LudicVocabulary's sets (JetBrains), ludic-mode.el's lists and the
language server's word tests (is_keyword_word and the rest; is_contextual_word is
every word the parser does not reserve, and every declaring or modifying one),
and every TextMate pattern marked "comment": "ludic-dev syntax: <group>" (shared
and the VS Code copy). The grammars gain module uses port bind action reducer
dispatch registry def open component prop view alias friend unsafe numbers of as
from mut system; import and extern colour as declarations; the phase clause
knows Overlay; the bitwise pattern matches | and ^ on their own again.
`ludic-dev syntax --check` - and check-vocabulary, whose old parser comparison it
replaces, and the regression suite (syntax_cases, one line per file) - fails when
a written list is behind, when a grammar lacks a keyword, type or phase, when
docs/language has no page for a keyword, type, phase or attribute, or when the
parser (a scan of selfhost/frontend: is_id / text == words, a == / ann ==
attributes) tests a word or reads an attribute vocab.ludic lacks, or the reverse.

- 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

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.

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.

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.
