Two ECS-native, deterministic namespaces for 2D motion, driven off the fixed
frame clock so replays and lockstep netcode reproduce every frame and every
eased value exactly. Both are pure computed-inline Q16.16 / integer math (no new
runtime, no heap) — the game stores a timer on a component and calls these each
frame, exactly the way Collision.* / Grid.* are used.
Anim.* — spritesheet frame animation:
- Anim.frame(timer,fps,count) -> int looping frame index
- Anim.once(timer,fps,count) -> int one-shot, clamps on the last frame
- Anim.pingpong(timer,fps,count) -> int bounce 0..count-1..0
- Anim.finished(timer,fps,count) -> bool has a one-shot run past its end?
- Anim.duration(fps,count) -> fixed seconds for one cycle
- Anim.cell_x/cell_y(frame,cols,cell) -> int source rect on a grid sheet
Tween.* — value interpolation over a timeline:
- Tween.progress/loop/yoyo(timer,duration) -> fixed normalized amount
- Tween.done(timer,duration) -> bool
- Tween.ease(t, mode) -> fixed shape by a literal curve 0..6,
the same curves as Ease.* (now
factored into a shared ease_eval)
- Tween.number/round/point/tint(from,to,t) blend a fixed / int / Vector / color
The typed blends reuse the existing fixed / Vector / color helpers, and
Tween.ease shares Ease.*'s exact formulas via the new ease_eval(mode,t) — one
source of truth for every easing curve in the engine.
examples/library/anim.ludic asserts 34 cases (frame math, clamping, ping-pong,
cell geometry, timeline clamp/loop/yoyo, rounding, color/vector blends, and
Ease.in == Tween.ease(.,1)); wired into x test (now 62 passed). Docs: Anim +
Tween sections with 16 per-symbol pages, inventory/coverage green. Seed
reseeded; the C-free bootstrap fixpoint holds.
The stateful sugar the proposal sketches (named clips, Anim.play, fluent
Tween.chain/parallel handles, and an auto-injected advance system) is deliberately
left as a follow-up — this lands the deterministic math core both halves stand on.

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.

A regular-expression library with PCRE/PECL-compatible syntax, implemented as a
Thompson NFA / Pike VM so a bad pattern from a modder can NEVER cause
catastrophic backtracking — matching is O(n·m), never exponential. `(a+)+$` on
40 non-matching chars, `(a*)*b`, `(.*a){20}b` all run in microseconds; a 50 KB
input scans in ~7 ms.
The engine (runtime/native/regex.ludic + regex_vm.ludic, ~700 lines of Ludic, no
C) parses a pattern to a small bytecode program — an unanchored lazy `.*?` prefix
makes a plain search match anywhere — and the VM runs every alive thread in
lockstep per input byte, deduped by program counter and carrying capture slots
(save/restore, leftmost-greedy priority). Supported: literals, `.`, classes
`[...]` (ranges, negation, `\d \w \s` and their negations), anchors `^ $`,
alternation `|`, capturing and `(?:…)` groups, and `* + ? {n} {n,} {n,m}` in
greedy or lazy form, plus the common escapes; numbered capture groups. Errors are
values — an invalid pattern compiles to null, never a crash. Backreferences and
look-around are out of scope for a linear engine, and on the degenerate case of a
nullable subpattern under an unbounded quantifier positions may differ from a
backtracking engine (the price of the linear-time guarantee) — documented.
Surface (Regex.*, aliased in emit_call.ludic to the regex_* functions):
compile / valid / matches / test / find / exec / next / replace / group /
group_count / start / end / ok.
The runtime is spliced on demand: the parser sets a flag when it sees `Regex.`
and maybe_splice_runtime imports the engine — so it costs nothing in a program
that doesn't use it and works in a plain tool (not just an ECS game).
Verified against Python's `re` as an oracle: a 20k-case grammar fuzzer agrees
100% on realistic patterns (0 / 15000 with capture groups) and 99.8% on group-0
spans across the full pathological grammar, the residual being the documented
nullable-quantifier case. examples/library/regex.ludic asserts the behaviour
(wired into `x test`, now 60 passed); docs: a Regex section + 13 per-symbol
pages, inventory + coverage green. Seed reseeded; the C-free bootstrap fixpoint
holds.

Follow-up to #31: the doc/lint/grammar checks moved to Ludic there; this ports
the remaining docgen piece (gen.py / check.py / palette.py) so nothing in the
documentation pipeline is Python any more.
Three new `x` subcommands, all in Ludic and compiled by Ludic:
- x docs-gen [--out DIR] the static-site generator: parses docs/language/**
front-matter + bodies (fences, Parameters:), builds the section/symbol
model, reads the asset templates, and emits every page + ns/color/api pages
+ the landing page + ludic-highlight.js + symbols.json + .nojekyll.
- x docs-check [DIR] the coverage / integrity guard (required files, a
page per inventory.json symbol, duplicate-token and one-dir-per-namespace
guards, highlighter link targets).
- x docs-palette the named-colour source of truth: the palette table
moved into tools/x/docgen.ludic, emitting emit_color.ludic (pointer, not
ptr) + palette.json.
Verified against the Python oracle: `x docs-gen` reproduces all 466 output files
BYTE-FOR-BYTE (a Ludic json.dumps/html.escape/front-matter port — ordered dicts,
indent=2 vs compact, ensure_ascii \uXXXX, codepoint-aware truncation), and
`x docs-check` matches check.py's pass/fail output. Wired into `x test` as a
gate (docs-gen -> docs-check on a fresh site; docs-palette stays byte-identical).
CI swap: ci.yml and docs.yml call the Ludic generator; docs.yml drops the
python:3.12 container and bootstraps the toolchain from the IR seed instead.
tools/docgen/{gen,check,palette}.py deleted; only assets/ + inventory.json
remain. Completes #31's criterion 3.

Until now the only workflow was docs.yml — nothing gated a change on the
compiler even building, on `x test` / `x test-tools`, or on the headline C-free
self-rebuild reproducing the seed. Add two Forgejo Actions workflows on the same
`docker` runner the docs job uses.
The toolchain is macOS-first: the self-hosted compiler emits the Darwin libc
standard-stream globals (`__stdoutp`/`__stderrp`), the one thing that stops its
IR from linking on Linux. Everything else is portable — clang-16 assembles the
seed cleanly and the C-free bootstrap reproduces it byte-for-byte on Linux too.
So rather than require a macOS runner (none is registered), bridge that single
gap with a tiny **C-free LLVM-IR shim** (tools/ci/linux_stdio_shim.ll) that
defines the Darwin-named globals over glibc's stdout/stderr, injected into every
clang link via LUDIC_CC. The language keeps its no-C-compiler guarantee.
Workflows:
- ci.yml — bootstrap the toolchain from the seed, then `x test` + `x test-tools`
+ the docs-cover-the-implementation checks, on push to main and PRs.
- bootstrap.yml — `x bootstrap-cfree`: assert the seed rebuilds itself
byte-for-byte (returns non-zero on drift).
Make the suites host-aware so a Linux run is green without hiding anything: a
new is_darwin()/skip() pair (tools/x/prelude.ludic) makes the cases that are
genuinely macOS-ABI bound — the Cocoa-windowed `ludicc -o` link, the golden
render hashes (blessed on macOS; text raster differs by a hair elsewhere), the
Os known-folder/uname surface, Fs.list and the LSP workspace walk (both read the
BSD dirent layout) — print a visible `skip` off Darwin instead of failing. On
macOS every one of them still runs: suites stay 56 / 29 / 29 green there, and
run 51 / 28 (+skips) on Linux, bootstrap-cfree byte-identical on both.
The formatting gate is ludic-fmt *idempotence* (already in `x test-tools`), not
`fmt(x) == x`: this codebase deliberately preserves hand alignment, so a strict
"already formatted" check would fight that contract.
A prebuilt CI image with clang-16 + python3 baked in is the obvious follow-up
speed-up (ties into the packaging work in #33).

A cohesive filesystem & IO library — the foundation for saves, config, mods, and
asset loading — wrapping the bare file_* builtins into one safe, ergonomic API a
non-expert can use without touching a file descriptor or a byte buffer.
Path.* join / dir / base / ext / stem / normalize (pure lexical string ops)
Fs.* exists / is_dir / read_text / write_text / append_text / remove /
size / mkdir / copy / list
Mime.* of (extension table) / sniff (magic bytes: PNG/JPEG/GIF/PDF)
Pure string IR for Path.*; libc (fopen/access/mkdir/rename/opendir…) for Fs.*;
C-free, emitted on demand (g_uses_fsrt). Safety and determinism baked in:
- write_text and copy are atomic (write a temp file, then rename over the target)
so a crash mid-write never corrupts the previous file;
- mkdir creates parents (mkdir -p);
- list is sorted for a stable, reproducible directory walk;
- fallible calls return values (null / false / -1), never crashes — ready for a
first-class try/else when the error-handling work lands.
Complements Os.* (#21): Os supplies per-user locations, Fs the operations. v1
targets the native macOS/BSD filesystem with "/" separators; Windows separators,
a sandboxed wasm virtual FS, recursive directory copy, and richer magic-byte
sniffing are documented follow-ups.
- examples/library/fs.ludic: 32 assertions across pure Path ops (incl. normalize
resolving ./ .. and duplicate slashes), a real create/read/append/copy/list/
remove cycle under build/, and Mime by-extension + by-magic (GIF signature vs a
.bin extension). Wired into `x test` (now 56 passed).
- docs: new Path, Fs, and Mime sections + 18 per-symbol pages; inventory updated;
every fence passes check-docs; site builds via docgen.
- seed regenerated; `x bootstrap-cfree` fixpoint holds.

Make Ludic text correct-by-default over UTF-8, so player names, translated UI,
and chat behave for every language instead of counting bytes and splitting
characters in half. The byte-oriented Text.* stays for speed; Unicode.* is the
layer that understands code points and (approximately) grapheme clusters.
- len / byte_len code points vs bytes — the two lengths, kept distinct
- is_valid_utf8 strict validation of untrusted input
- char_at / chars code-point access by index; chars() -> []int
- upper / lower case mapping (ASCII + Latin-1)
- truncate first n code points, never a half-character
- grapheme_len user-perceived characters (approx UAX#29)
Pure integer/byte IR over NUL-terminated buffers; C-free, no data-table blob.
Decoding and validation cover the full UTF-8 range (overlong/surrogate/>10FFFF
rejected). grapheme_len collapses combining marks, variation selectors, ZWJ
sequences (family emoji), and regional-indicator flag pairs. Documented v1
scope: wider-script/locale case rules (Latin-Extended, Greek, Cyrillic, Turkish
i, German ß) and NFC normalization are follow-ups.
- examples/library/unicode.ludic: asserts the invariants across ASCII, Latin-1
(é round-trips through upper/lower), a decomposed "café" (5 code points, 4
graphemes), a ZWJ family emoji (5 code points, 1 grapheme), and a flag (2
regional indicators, 1 grapheme). Wired into `x test` (now 55 passed).
- docs: a new Unicode section + 9 per-symbol pages clarifying byte vs code point
vs grapheme; inventory updated; every fence passes check-docs; site builds.
- seed regenerated; `x bootstrap-cfree` fixpoint holds.

An Os.* namespace, Go-flavored and game-scoped, for the environment *around*
the game: the command line, environment variables, standard streams, process
exit, the host platform, and the per-user known folders a game writes into.
Rounds the bare System.* builtins (arg/getenv/exit) into one coherent surface.
- args / arg_count / arg the argument vector (args() -> []string)
- env / env_or / has_env read env vars (null-safe via env_or)
- set_env / unset_env mutate this process's environment
- exit(code) terminate with a status code
- platform() / arch() host facts (uname sysname/machine)
- stdout_write / stderr_write raw writes to the standard streams
- save_dir / config_dir / cache_dir / temp_dir per-user known folders
Pure libc over NUL-terminated strings; C-free, no new runtime. arg_count/arg/
exit stay light (no prelude) as thin aliases of the existing intrinsics; the
rest share one Os runtime prelude emitted on demand (g_uses_osrt). platform()
is portable (uname system name is field 0 on every Unix); arch() and the
known-folder layout follow the macOS/BSD conventions — the fully supported
native target today. Linux/Windows/wasm folder resolution and a target-aware
arch() are documented follow-ups.
- examples/library/os.ludic: asserts the invariants that hold regardless of
host — env round-trip, env_or fallback, unset, args()==arg_count(), non-empty
platform/arch and known dirs. Wired into `x test` (now 54 passed).
- docs: a new Os section + 17 per-symbol pages; inventory updated; every fence
passes check-docs (--fmt) and the site builds via docgen.
- seed regenerated; `x bootstrap-cfree` fixpoint holds.

A Log.* namespace: five levels (trace/debug/info/warn/error), a runtime
threshold, and structured key=value fields, so games get something better than
scattered print calls and release builds can go quiet without touching call
sites.
- Log.trace/debug/info/warn/error(msg, [k, v]...) -> stderr, "[LEVEL] msg k=v"
- Log.set_level(n) show only level >= n (0 = all default, 5 silences all)
- Log.level() read the current threshold
Fields accept strings, ints, and longs (numbers formatted automatically); the
level tag is chosen at compile time so a filtered-out level costs only a
comparison. Writes to stderr, never touching the simulation — no effect on
determinism/replays. v1 is the console sink; rotating-file and in-engine overlay
sinks are noted as follow-ups.
- examples/library/logging.ludic: asserts the set_level/level threshold
round-trip and that every level (with mixed-type fields) runs without faulting;
the stderr gating itself was verified by hand (warn/error emit, lower levels
suppressed). Wired into `x test` (now 53 passed).
- docs: a new Log section + per-symbol pages; inventory and coverage pass.
- seed regenerated; `x bootstrap-cfree` fixpoint holds.

A Noise.* namespace for procedural generation, implemented entirely in Q16.16
fixed point over an integer permutation hash so a seed reproduces the exact same
field on every platform and run (native/headless/wasm) — the determinism edge
over float noise that drifts across CPUs.
- value2 / perlin2 / simplex2 — value, gradient, and simplex noise -> [-1,1]
- fbm2(x,y,seed,octaves) — fractal Brownian motion (octaves of simplex)
- cellular2 / cellular2_id — Worley F1 distance + nearest-cell id
- unit(n) — remap [-1,1] -> [0,1]
Covers issue phases 1–2 fully plus cellular from phase 3; domain warp, ridged/
billow, and sample1/sample3 remain as follow-ups. Pure integer IR, C-free;
cellular/fbm reuse the math prelude's fx_sqrt.
- examples/library/noise.ludic: asserts the invariants a fixed-point generator
must hold (Perlin == 0 at lattice points, every sampler within [-1,1],
reproducibility, seed sensitivity, non-negative cellular distance). Wired into
`x test` (now 52 passed).
- docs: a new Noise section + per-symbol pages; inventory and coverage pass.
- seed regenerated; `x bootstrap-cfree` fixpoint holds.

Crypto (#19): add the OS cryptographically-secure random surface
(random_bytes/random_hex/random_u32, reading /dev/urandom) and a standard
base64 encoder, completing the library alongside the existing SHA-256/
HMAC-SHA256/verify_hmac/hex/ct_equal. All pure integer IR, C-free.
Uuid (#16): a new namespace for stable, collision-free IDs — v4 (random) and
v7 (time-ordered) generation, plus parse/is_valid/to_text/equals/nil. UUIDs are
canonical lowercase 36-char strings; v4 and v7's random tail draw from the
crypto CSPRNG, so both carry the documented determinism caveat (mint at the
edges, never inside lockstep simulation). Reuses the crypto prelude's
fn_secure_bytes / fn_hex_encode.
- examples/library/{crypto,uuid}.ludic: known-answer vectors (SHA-256, HMAC,
base64 per RFC 4231/4648) and structural invariants (uuid version/variant
bits, parse/equals), wired into `x test` (now 51 passed).
- docs: per-symbol pages for every new method + a new Uuid section; inventory
and impl-vs-docs coverage check pass.
- seed regenerated; `x bootstrap-cfree` fixpoint holds.

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.

Finish issue #9 by adding the two remaining acceptance items on top of the
calendar/clock core, still pure-integer and deterministic:
DateTime.format(dt, pattern) -> string render an instant via a token
pattern (YYYY/YY/MM/DD/HH/mm/ss;
other chars pass through)
DateTime.parse(text, pattern) -> int read an instant back; -1 on a
non-digit where one is expected
Clock.now/set/advance/reset a game-controlled simulated clock
(the @L_clock global) that never
touches the wall clock, so gameplay
reading Clock.now() is replay-safe
format/parse take a string-LITERAL pattern and are expanded at compile time
(field offsets are then constant), folding @fn_str_concat over literal runs and
two small runtime helpers: @fn_dt_pad0 (zero-padded field) and @fn_dt_rd
(fixed-width digit reader that stops at the terminator and flags malformed
input). Clock is a universal i32 global declared in emit_head, so it works in
entry and game programs alike.
Adds examples/offline_rewards.ludic — the issue's worked "you were away N hours"
example, driven from its own entry and asserted in the regression suite — plus
selfhost/tests/datetime2.ludic (format/parse round-trip, parse failure, clock),
docs (Clock section + 4 pages, DateTime.format/parse pages), inventory and LSP
hover. Reseeded; C-free fixpoint holds; all suites green (27 self-host / 46
regression / 29 tools); check.py (366 symbols), check-impl.py (218 ns-methods)
and validate.py OK.
With this, #9's scope is fully delivered: DateTime/Date/Duration + core ops,
format/parse, a deterministic simulated clock, docs + offline-rewards example,
and tests. (v1 stays UTC-only, no leap seconds, i32 epoch valid through 2038.)

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).
Reseeded; C-free fixpoint holds; all suites green (45/24/29); site + check.py OK.

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).
