fn(int, float) -> bool is a type, fn name is any top-level function's value, and a call through
a local, a global, a record field, a slice element, a parameter or a result of a function type
is an indirect call; two function types mix only when equal, a call checks its argument count,
and a value may be null (examples/functions/values.ludic). Job.parallel_for keeps its worker
check.
render3d's scene is registered rather than required by name: r3d_on_draw, r3d_on_casters and
r3d_on_stream_fill (hooks.ludic). The two rendering examples register theirs - and had defined
scene_draw_casters with no parameter while the renderer passed one, which nothing checked.
render3d declares numbers float itself; smooth.ludic is converted to floats and returns when
r3d_init fails instead of running on into a segfault. Noise.* check their argument count (a call
one short crashed the compiler). selfhost-build says why it failed. The migration tool reads a
declared float as evidence. Seed regenerated.

L1. Two vars, consts, enums, properties or events of one name in a program are an error naming
both places (functions already were); the first used to win silently. A let / var of a name its
own block already declared is an error (it used to shadow). A function with a result type whose
body can reach its end without a return is an error, asked structurally of the body - a return,
an if/else or a match with a default arm whose every branch ends - rather than handing back
whatever the result slot held. The game, the lab and every package example pass all three;
the lab had one harmless shadow, and the game's split screens had two real bugs of the kind.
examples/rejected/ holds the four refusals, checked by the test runner's new reject_case.
Seed regenerated.

Text.to_float reads a leading decimal number (strtod), the twin of Text.to_int, for data files.
A return with a value in a function that returns nothing now says so where it is, instead of
reaching clang as 'store void'. Seed regenerated.

Listeners are compiled into one @ev_<E> function and return branched to its exit, so every
listener declared after one that returned early - and every foreign listener - never heard
the event. The per-kind listener shape (return unless it is my kind) answered only the
first-declared kind. examples/events/answer.ludic holds it; seed regenerated.

A numbers float file adapts decimal literals to a fixed operand or slot, and refuses to
promote a computed int to a float implicitly: there it is almost always float bits. Explicit
float(x) is always allowed.
render3d's numbers are float, converted by tools/migrate/floatbits.py - a whole-program
inference of which ints carried IEEE bits (union-find over flows, calls, returns, buffers,
nested buffers and lexical scopes) and a rewriter to operators, Math.* and float literals,
with float_bits / float_from_bits left only where bits really cross (runtime scratch
buffers, mixed buffers). Seed regenerated.

`reseed` writes both, and the committed Windows seed carried none of the bounds
check (0 sites against 859 in the regenerated one), so a bootstrap there would
have built a compiler without it - the same half-a-change as the host seed, on
the other platform.
Not verified by running: a Windows bootstrap cannot be done from this Mac. What
is checked is that it is generated by the same `reseed` from the same source as
the host seed, and that it carries the emission the host seed does. The host's
own bootstrap is a proven fixpoint and selfhost-test's C-free bootstrap passes.

The platform gave these keys no code at all, so a game's rebinding screen could not take
one and nothing said why. Windows asked the active layout what they type and got nothing
(w_vk_char answers 0 for a key with no character); macOS let them fall through to
charactersIgnoringModifiers, which reports NSF1FunctionKey and its neighbours at 0xF704
and up - outside the 256-bit held set either way.
w_keyval and ev_keyval now name them, with the same codes on both: 132-143 F1-F12,
144-149 Home / End / PageUp / PageDown / Insert / Delete, 150 Caps Lock, 152-161 the
numpad digits, 162-166 its * + - . and /. The numpad's Enter is Enter.
Key.F1, Key.Home, Key.Numpad0 and the rest fold at compile time, and Input.key_label
names them without asking the layout - a key that types nothing is called the same thing
on every layout.
examples/library/input_typeless_keys.ludic covers the codes, the names, the held set and
the press edge; 150 passed in ludic-dev test, 33 in selfhost-test.

Crypto.random_* and Uuid.* read /dev/urandom, which Windows lacks, so every
byte was zero; the Windows target now calls RtlGenRandom (advapi32).
ludicc takes --title, which ludic build/run/bundle pass from package.ludic's
app name, so rt_init opens the window under that name instead of the
program name.

Process.spawn/poll/kill/free - non-blocking child processes with no shell: posix_spawn on
macOS (process.ll), CreateProcessW with MSVC-quoted arguments and no console window on
Windows (process_win.ll), linked only when a program uses Process.*.
Http.save_to streams a response body into a file (NSURLSession with a run-time delegate
class on macOS, the WinHTTP read loop on Windows); Http.received / Http.expected report
progress while it is pending. Freeing a pending request cancels it and parks the slot
until the worker has finished.
App.window_hide / App.window_show take the game's window off the screen and back without
closing it; the run goes on while hidden. Docs, examples, tests and a changeset.

uses Udp.*; example, docs and tests.

emit_bin_vals lowered every pointer-typed ==/!= to @lp_str_eq, so two
distinct records compared their bytes up to the first zero byte. Content
compare now needs both sides to be text (string, or the untyped
pointer/ptr runtime code carries text in); other references use
icmp eq ptr, and string vs a non-text reference is a compile error.
Adds selfhost/tests/identity.ludic; both seeds regenerated.

`float` (32-bit) and `double` (64-bit) with + - * / %, comparisons and unary minus.
Decimal literals take their type from context and stay `fixed` elsewhere; int and long
promote implicitly (LUDIC_WARN_FLOAT_PROMOTE=1 lists every promotion). float(), double(),
int(), long() and fixed() convert; floats(n)/doubles(n) buffers; float fields, globals,
constants and parameters; Math.* computes in float for float arguments; string/print
write the shortest round-tripping decimal; float_bits/float_from_bits expose the bits.
@deterministic code may not use floats. The f_* runtime helpers stay as they are.

The Windows runtime keyed the held set by the character MapVirtualKeyA gave a
virtual key, so a game's WASD belonged to whatever the active layout put there,
and with an input method on every letter arrived as VK_PROCESSKEY. The typing
block is now read from the scancode (the arrows, numpad and F-keys still by
virtual key); macOS reads keyCode the same way. Input.key_label(key) names a key
in the player's own layout (Windows) or as its US character elsewhere.
Verified on Windows with SendInput into a live window: VK_Z carrying W's scancode
holds 'w', VK_PROCESSKEY carrying A's holds 'a', Caps Lock changes nothing.

`fn name` read `while p < fn and ...` as a reference to a function called `and`, which broke
tools/ludic-cli/glgen.ludic and so the dev tool's own build. A reference now needs the name on
the same line and not one of and / or / not / in / is. The threads example checks `fn` as a
local before `and`. Reseeded; bootstrap-cfree reproduces the seed.

- `fn name` names a top-level function as a value (E_FNREF, lowers to @fn_<name>); the worker
entry point for Job.parallel_for, which checks it takes (int, pointer-like) and returns void.
- runtime/native/threads.ll (pthreads) and threads_win.ll (Win32 SRWLOCK/CONDITION_VARIABLE): a
pool of one worker per core but one, parked between batches; every thread claims chunks by
compare-and-swap. Linked only into programs that use Job/Promise/Sync, by `ludicc -o`,
`ludic build` and the test suite's build helper.
- Sync.* is real: native mutexes, atomics as cmpxchg retry loops (neither clang takes atomicrw,
the PC's rejects seq_consistent), mutex-guarded channels, Sync.cpu_count from the OS.
- spawn/despawn on a pool thread stop the program with a located panic.
- examples/library/threads.ludic and its test; docs for fn, Job.parallel_for, Job.is_worker.
- Reseeded (bootstrap-cfree: out.ll == seed.ll). 141/141 on macOS; jobs, threads and the guard
pass on Windows from the reseeded Windows seed.

ludic-dev vkgen reads vk.xml into runtime/native/vk_api.ludic (constants, every struct's
<Struct>_sizeof and <Struct>_<field> offsets, one extern per command) and vk_thunks.ll.
Every size and offset was compiled against the SDK's C headers; `ludic-dev test` checks the
tracked files against the registry wherever the Vulkan SDK is installed.
vk_win.ll (vulkan-1.dll) and vk_mac.ll (libvulkan.1.dylib, MoltenVK) open the loader at run
time, so a program built with Vk.* starts on a machine without Vulkan. ludicc and ludic
build link both for any program that uses Vk.*. The seeds are regenerated for the new
compiler.
vk_probe reports what a machine's Vulkan can do; vk_compute dispatches a Slang compute
shader and reads the picture back, clean under the validation layer on an RTX 3070 Ti and
on an M4 Pro through MoltenVK.

The CLI's shell commands go through shell(), which is run() on POSIX and a
scratch script handed to Git for Windows' bash on Windows (exit codes read
directly there). compile_app links through `ludicc -o` on Windows, ludic run
starts the .exe, and ludic-dev build and ensure_ludicc assemble
selfhost/ludicc.win.seed.ll, which ludic-dev reseed now writes beside the
macOS seed. ludic bundle makes build/<name>/ with a GUI-subsystem exe carrying
the .ico beside `app icon` as an llvm-rc resource, game.lpak and packs.index;
ludicc gains --gui and --link, and quotes its whole link line for cmd.exe.
Verified: ludic-dev test 135/135, selfhost-test 32/32; on the PC a checkout
bootstraps from the Windows seed, ludic-dev build makes the toolchain, and
`ludic bundle` makes build/Maroon Lake/, which runs from its own folder.
