rt_init opened every windowed program's window before main, and render3d's gvk_open then only
retitled it. win_open makes the window when there is none (cocoa.ll and win32.ll alike), so for a
program that has gvk_open the runtime now leaves it (window_later(), an intrinsic: windowed and
render3d present): a process that never reaches the renderer - Maroon Lake's launcher watcher, which
only spawns the game and waits - never makes a window, an NSApplication or AppKit's heap.
Audited every window native reachable before the renderer opens (settings, telemetry, rescue, the
watcher reach App.* and Input.*): on macOS each that loads W_win / W_app / W_view / W_mtl / W_glctx
checks it for null; win_close, win_running, win_text, win_held, win_cursor_mode, win_gl_scale and the
pad and touch reads load none. On Windows each that loads W_hwnd / W_hdc checks it; the rest load none.
Measured, windowed, R3D_DEV=1 R3D_PLAYTEST=2, both killed after:
- the game straight to play: the window, the Vulkan swapchain (1920x1080) and the valley's models
come up, alive at 30 s;
- the launcher (R3D_GAME=launcher): the watcher 11 MB -> 3.7 MB, its launcher window alive at 10 s.

The seeded random numbers lived in the ECS runtime, so a tool or a
program of test blocks got "unknown function rng_range". They are
runtime/native/rng.ludic now, spliced on Random.* or a bare rng_*/seed
call nobody defines, and imported by core.ludic for a game. A bare
value_*/json_* call nothing in the program defines splices the value
tree the way Value.* does. Reseed.

The typed buffers are slices: words/floats/fixeds/doubles/pointers(n) make
zeroed, bounds-checked []int/[]float/... and the type names mean them. buffer(n)
is a []byte, with text_of, Fs.read_bytes/write_bytes and view(xs, start, n).
bytes(), indexing a raw pointer or bytes, free, resize, Memory.*, raw file calls,
data_of and C externs are refused outside unsafe { } / unsafe function, and a
project's own files may write unsafe only with --unsafe; the runtime and packages
are the platform. A slice passed to an extern goes as its data.
What the change found: Sync's atomics on a slice header, words(n) uninitialised,
input's fixed axes in ints, truetype's fixed outlines as ints, skin matrices
typed int, gl_shader's source table made from raw bytes. render3d gets safe
entry points (safe_api.ludic). Rendering is byte-identical; a frame costs the same.

- runtime: HEADLESS_FRAME_PATH, STICK_DEADZONE / STICK_LEFT_X/Y, key and
byte codes as char literals throughout (`k == 'w'`, `fill(rt_map, ' ', …)`)
- ludic.gameplay/stats: drop the duplicate `stat_field` (it answered "atk"
for every build stat); Stats.base uses stats_field_name
- ludic.shooter: compare aim modes and fire patterns with AimMode.* and
WeaponPattern.* instead of raw ints; STICK_RIGHT_X/Y
- ludic.npcai: DecisionMade / brain_set_state use AiState.*
- examples/games/menu.ludic uses Font.load / Ui.* with FONT_PATH and
BACKDROP named; strings.ludic header says what it prints
- whole tree: `x = x + 1` → `x += 1` (single-term right-hand sides only),
`0 - x` → `-x`, ASCII codes → char literals; every .ludic and every
```ludic fence reformatted with the fixed formatter (whitespace only)

Closes the two open issues and lands the pending unreleased batch:
- #90: `Sprite { atlas: 1 }` routes esys_sprite through atlas_draw_ex
(scale/flip/tint), so cell / cell_span / strip ids of any size draw
through the engine sprite-render system. examples/library/sprite_atlas
is the pixel-readback regression.
- #91: `become` from an @On(Event) listener / global handler / plain
function no longer segfaults the compiler; it emits @L_scene_leave()
(a dispatch on the live scene id) so the leaving scene's on-exit runs.
UI_* handles are readable from any code (widget table built on first
use). examples/library/scene_menus covers it.
- fix: a windowed `ludicc -o` build that reaches the audio runtime only
through the atlas/Assets preload import now links audio.ll +
AVFoundation (the audio backend link was gated on a game-level
Audio.* call, so any windowed game declaring Sprite failed to link).
- the hand-written "Unreleased" CHANGELOG section is converted to
changesets under changes/ so `x release` generates it.
- plus the batch: engine-driven retained UI + UiClicked event, Overlay
phase, TileSkin tilemap-render system, Key.* constants, Font/Ui/File
namespaces, Sprite.strip, prefabs, managers, countdown fields,
enum-typed machines, layer @Queries, ludic.prefs / ludic.dungeon
packages, Ai.seek pathing, Solids.solid2, cursor confine (mode 3)
fix, shooter centre-aim fix, reserved-word function diagnostic.
Verified: x test (124/124), x test-tools, check-impl, check-vocabulary,
check-docs, docs-gen + docs-check, bootstrap-cfree (seed is a fixpoint).

The #78 investigation rejected hardware f32/f64 for the coordinate types
(they would desync lockstep/replay/save) and identified camera zoom as the
one genuinely-missing render feature. Ship it: Camera.zoom(scale) scales the
whole view about the screen centre by a Q16.16 factor, threaded through the
same two framebuffer chokepoints (rt_put_px/rt_fill_rect) that carry the
camera offset, so it composes with Camera.set/follow/shake. Gated by an
internal rt_cam_zoomed flag so a game that never zooms renders byte-for-byte
identically (golden renders unchanged); Camera.zoom(1.0) turns it back off.
The world coordinate types stay integer px + Q16.16 velocity, so it's a pure
render-time transform and itself deterministic.
Example examples/library/camera_zoom.ludic (pixel-readback verified),
docs page, RFC updated (docs/RFC-POSITION-TYPES.md). Full suite 105/0,
fixpoint holds.

Completes the transform/state-based rendering #23 tracked as blocked on new
renderer state. All of it threads through the two framebuffer chokepoints every
draw primitive already funnels through (rt_put_px / rt_fill_rect), so one place
gives the whole draw API a camera, a clip rect, and a blend mode. Defaults are
neutral — camera (0,0), clip = full screen, blend = replace — so every existing
golden render is byte-identical (the 60+ render tests still pass unchanged).
New renderer state (runtime/native/core.ludic):
- Screen.camera(x, y) / Camera.set(x, y) world-space draw offset; a world
point draws at (wx-x, wy-y). Moves
everything — reset to (0,0) for a HUD.
- Camera.follow(x, y, lerp) ease the offset toward centring a
target (fixed lerp 0..1)
- Camera.shake(amount) +/- amount jitter from the seeded RNG
(replay shakes identically); 0 clears
- Screen.clip(x,y,w,h) / clip_reset() screen-space clip rectangle
- Screen.blend_mode(m) 0 = replace, 1 = additive (clamped)
New primitives:
- Screen.oval(x, y, rx, ry, color) axis-aligned ellipse outline (midpoint)
- Screen.measure_text(text) -> int advance width in the 5x7 font
- Screen.pixel(x, y) -> int read a framebuffer pixel (0x00RRGGBB)
Everything stays integer and deterministic (the camera, shake, and blend all
reproduce exactly under identical inputs), so headless renders remain diffable.
Camera.follow interpolates in the fixed domain (fixed*fixed then floor) to avoid
the int*fixed coercion trap.
Screen.pixel makes the whole surface testable by reading rendered pixels back:
examples/library/render.ludic asserts 18 cases — pixel round-trip, camera and
Camera.set/follow offsets, clip in/out + reset, additive blend with 255 clamp,
oval extremes vs hollow centre, and text measurement — all verified against the
actual framebuffer, not just that the call compiled. Wired into x test (now 65
passed). Docs: 7 new Screen pages + a Camera section with 3 pages,
inventory/coverage green. Seed reseeded; the C-free bootstrap fixpoint holds.

Grid.* operates on the Map tilemap (Map.size/Map.row): a cell is passable unless
it is out of bounds or holds the caller's `wall` tile (a char code, e.g. '#'), so
any impassable glyph works. Everything is integer and deterministic.
- Grid.line(x0,y0,x1,y1) -> []Cell Bresenham line cells (LOS/raycast base)
- Grid.blocked(x,y,wall) -> bool the shared passability test
- Grid.line_of_sight(x0,y0,x1,y1,wall) unobstructed straight line?
- Grid.flood(x,y,wall) -> []Cell 4-connected reachable region (BFS)
- Grid.a_star(x0,y0,x1,y1,wall) -> []Cell shortest 4-connected path (A*,
Manhattan heuristic), empty if unreachable
The engine (runtime/native/grid.ludic, ~150 lines of Ludic, C-free) is spliced
into a game via core.ludic since it reads the tilemap runtime; returned Cell
slices are ordinary Ludic slices (`len` / `[i]`; each cell has `.x` `.y`).
Pathfinding lives under Grid rather than a `Path` namespace — that name is
already the filesystem-paths library (#10).
Verified against Python references: a 1500-case fuzzer over random maps agrees
exactly on A* path length (optimal, == BFS), flood-fill count, and line-of-sight.
examples/library/grid.ludic asserts the behaviour and is wired into `x test`
(now 61 passed); docs: a Grid section + 5 per-symbol pages, inventory/coverage
green. Seed reseeded; the C-free bootstrap fixpoint holds.
Scope: this lands the Grid.*/pathfinding half of #24. The ECS Query.* helpers
(count/first, and nearest/within which want a runtime spatial index) remain the
tracked follow-up the issue calls out as blocked.

Repository-cleanup / DX pass folding three tracker items into one coherent
change, verified green end to end (`bin/x test` 49/0, `bin/x selfhost-test`
29/0, `bin/x test-tools` 29/0).
#28 — curate & categorise examples/
- 42 flat entries regrouped into intent-revealing subdirs: games/, rendering/,
ecs/, events/, networking/, lang/, library/ (was lib/).
- chronorift dir-vs-file duplication resolved: the entry file and its import
modules now live together under games/chronorift(.ludic).
- Every path reference updated repo-wide (test runner, editor-tool drivers,
docs/site, design docs).
- New examples/README.md indexes the whole set with run commands.
- Showcase examples without a self-asserting entry (hello, events, net_rt) now
get a compile-only rot guard in `bin/x test`, so nothing here rots silently.
#30 — text-diffable golden baseline
- The 4 binary selfhost/golden/*.ppm blobs are replaced by a single
selfhost/golden/renders.sha256 manifest (SHA-256 per render). Hashes are
byte-identical to the old PPMs, so the baseline is unchanged — only its form.
- game_case now compares framebuffer hashes; a regression shows as a changed
hex line in review, not "binary files differ".
- New `bin/x golden` regenerates the manifest deliberately (review with
`git diff selfhost/golden/renders.sha256`).
#27 — PPM & asset handling
- Headless renders now write build/out.ppm, never the repo root; `x app`,
`x clean`, messaging and .gitignore updated to match. Nothing is written to
the working root any more.
- Redundant local Kenney .zip archives removed (the art ships extracted;
.gitignore already excludes *.zip). CC0 License.txt files retained.

Expand the abbreviated pointer types to full words on the language surface:
ptr -> pointer (a raw address / FFI handle)
ptrs -> pointers (a buffer of pointers)
The Ludic type name is distinct from LLVM's own `ptr` spelling: llty() maps
`pointer`/`pointers` to LLVM `ptr`, and the emitted IR keeps `ptr`, so only
the Ludic-level surface changes. Rewrites type annotations across all
sources, the 8 hardcoded pointer type-tags, the `pointers`-buffer indexing
in emit_addr, the grammars/LSP/JetBrains tokens, and the docs
(type-ptr -> type-pointer, type-ptrs -> type-pointers). int/bool keep their
conventional short spelling (like Math).
Reseeded; C-free fixpoint holds; all suites green (45/24/29); site + check.py OK.

Expand the abbreviated string type and its conversion builtin to the full
word everywhere:
str -> string (the immutable-string type)
str(x) -> str -> string(x) -> string (the stringify builtin;
what `{…}` interpolation calls)
Types are recognized by identifier, and llty maps both spellings to LLVM
`ptr`, so this is an atomic source rewrite: type annotations, the Ludic
type tags, the builtin name/dispatch, and the interpolation desugar, plus
the grammars, LSP, docs (type-str -> type-string, fn-str -> fn-string), and
inventory. int/bool stay (universally accepted, like Math).

Expand the function-declaration keyword to the full word across the whole
language and toolchain:
fn name(...) -> T { ... } -> function name(...) -> T { ... }
Done as a self-hosting migration: teach the parser both spellings, reseed,
rewrite every .ludic definition to `function`, then drop `fn`. The compiler
now rejects `fn`. Touches the parser, all selfhost/tools/runtime/example/test
sources, the grammars (TextMate shared+vscode, ludic_syntax.h, JetBrains
LudicTokens.kt), the LSP and formatter, the Python doc/vocab tools
(check-impl, check-docs, validate, palette, test-lsp), and the docs
(fences, prose, kw-fn -> kw-function).
Reseeded; C-free bootstrap fixpoint holds. All suites green (45 regression,
24 self-host, 29 tool); the docs site generates and check.py passes.

Implement the bulk of the namespaced-stdlib proposal (workshopsoft/ludic#2):
156 namespace methods across Math, Text, List, Ease, Collide, World, Net,
Sys, Save, Mem, extended Screen, Color functions, extended Random, and Time.
All deterministic fixed-point; self-hosting (C-free bootstrap fixpoint holds).
Compiler (selfhost/):
- Math.*: sqrt/sin/cos/tan/atan2/asin/acos (fixed-point runtime prelude —
bit-by-bit isqrt, 256-entry interpolated sine table, Ross atan2), plus
hypot/dist/dist2/deg_to_rad/rad_to_deg/posmod/wrap/ping_pong/snapped/
move_toward/smoothstep/lerp/remap/sign/floor/ceil/round.
- Text.* (complete): upper/lower/trim/repeat/pad, split/join/replace,
and the libc-backed queries.
- List.* (complete): insert/remove_at/remove/sort plus the earlier ops.
- Ease.* (in/out/in_out/back/bounce) and Collide.* (rects/point_rect/
circles/rect_circle).
- Phase 3: World/Net/Sys/Save namespaced over the bare builtins (byte-
identical IR) and Mem.* (bytes/words/copy/fill/peek/poke).
- Screen.* extended (line/circle/fill_circle/triangle/fill_triangle via new
runtime primitives; sprite/sprite_scaled aliases), Color.* functions,
Random.* (value/int/sign), Time.* (frame/delta/elapsed/now — new
game-loop frame counter).
- Fix a lexer bug: fixed-point literals with >4 fractional digits overflowed.
Docs & tooling:
- 129 new per-symbol doc pages; gen.py made data-driven (namespaces
discovered from the docs, no hardcoded list); new check-impl.py enforces
that every implemented namespace method / keyword / type / phase has a
doc page, wired into `x test-tools`. Document the previously-undocumented
keywords (break/continue/where/entry/new/public + and/or/not tokens).
- LSP: namespaced signature help (ns_method_sig) covering every namespace.
Tests: 12 new self-host/regression tests + a golden render for the drawing
primitives. All suites green (selfhost 21, regression 45, tools 29).

An opinionated, game-facing surface for the language:
- Color.<Name>: 221 named colors resolved to 0xRRGGBB at compile time
(selfhost/emit_color.ludic).
- Namespaced builtins Screen.* / Input.key / Random.* / Map.*, so calls read as
subject.action; present() -> Screen.show(), clear -> Screen.clear,
fill_rect -> Screen.fill_rectangle, etc.
- Named arguments, e.g. Screen.fill_rectangle(x:, y:, width:, height:, color:),
reordered to the callee's parameters at emit time.
- machine/become can run over a named program-scope var, not just a register.
- Migrate examples off numeric registers to named vars; snake/menu/chronorift
render byte-identical to the goldens and the bootstrap fixpoint is preserved.
- Regenerate the checked-in seed (selfhost/ludicc.seed.ll).

Groups B and C of the leftover-primitive cleanup — renames, not new machinery,
and deliberately NO unsafe_ prefix (a __-prefix is itself a C convention, and an
`unsafe` marker carries no signal in a fully-manual-memory language with no safe
subset to contrast against).
memory: mem_free -> free mem_realloc -> resize mem_set -> fill
ptr_add -> offset
process: os_argc -> arg_count os_arg -> arg os_exit -> exit
os_system -> run os_getenv -> getenv read_byte -> read_char
dead: mem_copy, os_time, write_byte (0 uses) — deleted
Two reseeds: accept both old and new names in the intrinsic dispatch, then
migrate every call site and drop the old names. file_open/read/write/seek/tell/
close are left as-is — they're the domain-prefixed syscall layer wrapped by
read_file, not the argc/argv-style C-ness the audit targeted; a `File` type is a
separate, larger design if wanted.

Allocation reads as intent, not malloc:
mem_alloc(64) -> bytes(64) (64 bytes -> a byte buffer)
mem_alloc(w * h * 4) -> words(w * h) (w*h 32-bit words)
bytes(n) mallocs n bytes and returns a plain pointer (byte-indexed); words(n)
mallocs n*4 bytes and returns a `words` pointer (int-indexed). Since words(X) and
mem_alloc(X*4) allocate the identical number of bytes, the migration cannot change
any allocation size — the `* 4` factor just moves from the argument into the
allocator name, pairing naturally with the Phase-7j `words` retyping
(`var fb: words = words(w * h)`).
Migrated 102 sites (mem_alloc(E*4) -> words(E), else bytes(E)); deleted the
mem_alloc intrinsic. mem_realloc/free/copy/set stay as the low-level

32-bit word access is indexing now, not peek32/poke32:
peek32(ui_rx, i) -> ui_rx[i] (reads an int)
poke32(rt_fb, i, c) -> rt_fb[i] = c (writes an int)
A buffer typed `words` (a pointer whose elements are i32) indexes with `w[i]`
as a full int; a plain `ptr`/`str` keeps byte indexing. emit_index_addr picks the
element type from the base's type — byte-identical IR to the old intrinsics, so
the migration reproduces the compiler and every golden render exactly.
The ~60 word buffers (rt_fb, tt_*/gc_* font tables, png_px/spr_px pixels, ui_*
layout arrays) were retyped from `ptr` to `words` scope-aware (per-function, so
the s/out/p byte-vs-word name collisions across functions stay correct), then the
254 peek32/poke32 sites migrated to indexing. A scope-analysis miss left 12
buffers (gc_*, sc_d, ui_rx/ui_ry) un-retyped — caught as a menu golden diff and
fixed. No true mixed byte+word access exists on any one variable, so a per-buffer
element type is sound.

Raw byte access is now indexing, not C-style peek/poke:
peek8(src, i) -> src[i] (reads a byte, widened to int)
poke8(out, j, r) -> out[j] = r (narrows the int to a byte)
E_INDEX on a non-slice pointer/string lowers to a `getelementptr i8` + load/zext
(read) or trunc/store (write) — byte-identical to the old peek8/poke8, so the
migration reproduces the compiler exactly. A "byte" element type (llty i8) drives
the widen/narrow. The compiler's own byte work now reads naturally, e.g.
`is_slice_ty` is `t[0] == 91 and t[1] == 93`.
Subtlety fixed on the way: g_addr_ty (the out-param carrying the indexed element
type) must be set AFTER evaluating the index expression, since a member/index in
the index would otherwise clobber it — doing it early made a byte read load a
full pointer from a byte address and crash the self-compile.
Two reseeds: add byte-index support keeping peek8/poke8, then migrate 148 call
sites and delete the intrinsics (+ the now-dead emit_gep_i8). Vocabulary drops

`null` is now a real pointer literal and null-tests are comparisons, instead of
`ptr_null()` and `ptr_is_null(x)`:
ptr_null() -> null
ptr_is_null(x) -> (x == null)
not ptr_is_null(x) -> (x != null)
Mechanics: a new E_NULL primary (`null`, like true/false) lowers to the `null`
pointer; emit_bin's comparison path now picks `ptr` vs `i32` from operand type
(via llty), so `==`/`!=` work on any pointer/record/slice. The two intrinsics are
deleted.
Two reseeds: (A) add the literal + ptr comparison keeping the intrinsics; (B)
migrate all 182 call sites (compiler + runtime, via a balanced-paren script that
skips string-literal args and rewrites `not ptr_is_null` to `!= null`) and delete
the intrinsics. Node/Val/Buf/Tok field defaults now read `ptr = null`.
Vocabulary drops the two from LUDIC_INTRINSICS; `null` joins true/false as a
language constant (grammar + ludic_syntax.h). LANGUAGE.md notes the literal.

First step of the "stop feeling like C" pass. Bitwise ops were functions
(`band(x, MASK)`, `shl(a, 3)`); they are now real operators:
band -> & bor -> | bxor -> ^ shl -> << shr -> >> bnot -> ~
Precedence is Go-style so the C footgun is gone: `<<`/`>>`/`&` bind like `*`,
`|`/`^` like `+`, both tighter than comparison — `flags & MASK == 0` parses as
`(flags & MASK) == 0`. `>>` is logical (lshr), matching the old `shr`.
Mechanics: lexer tokenizes `<< >> & | ^ ~`; p_mul takes `<< >> &`, p_add takes
`| ^`, p_unary takes `~`; emit_bin routes them through the existing int arith
path (arith_code gains and/or/xor/shl/lshr) and E_UN handles `~`. The six
intrinsics are deleted.
Delivered as two reseeds: (A) add the operators keeping the intrinsics, (B)
migrate every call site to operator form (85 lines across compiler + runtime,
via a balanced-paren call->operator script; two multi-line big-endian reads in
image/truetype done by hand) and delete the intrinsics. Vocabulary drops the six
from LUDIC_INTRINSICS (ludic_syntax.h, grammar, LudicTokens.kt) and the grammar
gains a bitwise-operator rule. LANGUAGE.md precedence table rewritten.
Reseeded (21724 lines); C-free fixpoint holds; goldens byte-identical (the PNG
and TrueType decoders lean on these ops); 17/17; vocab + doc-fences clean.

Bindings now signal mutability the way Rust/Swift do, instead of `let` meaning
"local" and `var` meaning "module-level":
- `let x = e` -> immutable binding; a later `x = …` is a compile error
(`cannot assign to immutable 'x' … use var`).
- `var x = e` -> mutable binding, at local OR module scope (position decides
scope; the keyword decides mutability).
- `const` -> unchanged (compile-time).
Immutability is of the *binding*, not the object: `let n = new Node; n.kind = 1`
is fine (mutation through the reference); only rebinding `n` is rejected. The
check lives in emit_assign — a direct `name =` whose target is a `let` local
(loc_mut == 0) errors; field/index targets and `var`/param/loop bindings are
unaffected.
Delivered as three reseeds so the self-hosting compiler never had to compile
source its own rules would reject:
A) add `var` as a local statement + per-local mutability tracking (loc_mut),
no enforcement;
B) migrate every reassigned `let` -> `var` across the compiler, runtime and
examples (337 declarations), driven by a per-function, string/comment-aware
scan (binding targets only, never `x.f =` / `x[i] =`);
C) turn on the check. bootstrap-cfree (compiler vs its own source) and every
golden build (which splices the runtime) then proved zero reassigned `let`
was missed anywhere.
Also folded in: removed leftover debug instrumentation in block() (a `cur=` /
print_int(777…) trace on the separator-error path) and fixed parse.ludic's stale
header comment (no more `struct`). Reseeded (21711 lines); C-free fixpoint holds;

Fixed the naming inconsistencies the cohesion audit flagged, converging on the
domain-first style the bulk of the surface already uses (ui_*, text_*, rng_*,
font_load, image_load):
- load_png -> png_load (asset loaders were split: font_load/image_load
- load_sprites -> sprites_load were domain-first, load_* were verb-first)
- setreg -> set_reg (missing underscore vs ui_set_int/ui_set_text)
Game builtins resolve to their `rt_` runtime function, so the renames are in
runtime/native (rt_png_load, rt_sprites_load, rt_set_reg) plus the ~100 example
call sites; `become` lowering in emit_machine now emits @fn_rt_set_reg. Purely a
surface rename — every renamed call maps to the same runtime symbol, so behavior
and golden renders are byte-identical.
Vocabulary + docs updated (ludic_syntax.h, grammar, LudicTokens.kt, LANGUAGE.md,
README, SYNTAX-REDESIGN). Reseeded; C-free fixpoint holds; goldens identical;
17/17; vocab clean.
Left as-is: os_argc/os_arg (compiler-internal intrinsics, already namespaced and
consistent with each other; renaming would need a bootstrap dance for little
gain). reg/set_reg keep the getter-bare/setter-set_ shape ui_focused/ui_set_int
