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.

Documentation namespace cleanup (issue #38).
Audit outcome:
- `date` vs `datetime` are NOT duplicates — `Date` is calendar days since the
epoch, `DateTime` is instants (seconds); distinct runtime namespaces. Kept
both.
- `network` vs `networking` WAS a real duplicate. Every other stdlib area
documents only its namespace (`World.*`, `Screen.*`, …), never the bare
builtins it lowers to. Networking alone also documented the low-level
`net_*`/builtin forms under `networking/`, duplicating the `Network.*`
pages under `network/`. Removed `networking/`; `network/` (the `Network`
namespace, which the compiler and LSP both expose) is canonical. Folded the
`@Sync`/`@Owned` framing into `network/_section.md` so no context is lost.
- Dropped the `networking` key from docgen inventory.json.
Guard (AC3): `tools/docgen/check.py` now fails if any `ns:` is documented from
more than one directory, or if two sections share an id or (case-folded)
title — so a duplicate-namespace split cannot silently reappear.
`gen.py` + `check.py` pass (34 sections, 365 symbols).
Closes#38

The security-sensitive counterpart to the fast, non-cryptographic Hash.*
library: standard, test-vector-backed hashing for signed saves and message
integrity, kept in its own namespace so nobody reaches for the wrong tool.
Crypto.sha256(s) SHA-256 -> 64-char lowercase hex
Crypto.hmac_sha256(key, msg) HMAC-SHA256 -> 64-char hex
Crypto.verify_hmac(key, msg, mac) recompute + constant-time compare -> bool
Crypto.hex(s) lowercase hex of a string's bytes
Crypto.ct_equal(a, b) constant-time string equality
The primitives are implemented from scratch in plain integer LLVM IR
(FIPS 180-4 / RFC 2104): no libc crypto, no data-dependent branches in the
compression rounds, so a given input hashes to the same 32 bytes on every
platform and run. Digests are returned as hex strings, not raw bytes, because
a `str` is null-terminated and a raw digest can contain a NUL. MAC checks use
a non-short-circuiting compare so timing does not leak how much of a forged tag
was correct.
Emitted on demand via g_uses_cryptort, mirroring the emit_hash prelude gate.
Scoped to the deterministic, known-answer-testable core; OS-backed
random_bytes (the one piece that can't be validated by test vectors) is left
for a follow-up.
Tested against published SHA-256 vectors (empty/"abc"/fox + 55/56/64-byte
multi-block padding) and HMAC-SHA256 vectors; wired into the self-host suite as
`crypto`. Docs: a new Crypto section with honest "what this protects / does
not" guidance, one page per method, all fences checked and in the inventory.

Grow List sorting from a numeric-only insertion sort into a small,
game-friendly toolkit that sorts records and query results by a key or a
full comparator, stably and in O(n log n).
- List.sort_by(s, keyfn) ascending by a key (draw order, price)
- List.sort_desc_by(s, keyfn) descending (leaderboards)
- List.sort_with(s, cmpfn) full cmp(a,b)->int comparator (multi-field)
Comparators/keys are passed as named top-level functions rather than
lambdas, so the toolkit ships without waiting on closures (#1).
Engine: a stable bottom-up merge sort. emit_takeright is the single
place stability is decided ("take the right run's head only on a strict
win" -> equal keys keep prior order). List.sort becomes a hybrid:
insertion sort for n<32, merge sort above; both stable, so output is
unchanged. Key functions must return an integer-ish type; record slices
hold pointer elements, so the key/comparator receives the record pointer.
Tests: selfhost/tests/sort.ludic (scalar large-n, sort_by, sort_desc_by,
stability, sort_with). Docs: list-sort_by/desc_by/with + updated
list-sort. All suites green (28 self-host / 46 test / 29 test-tools);
reseeded, C-free bootstrap fixpoint holds.

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.)
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Implement the calendar/clock half of #9 as plain-i32 integer epochs — no
new type, no floating point (the issue's "integer epochs to avoid drift") —
so every operation is deterministic and bit-identical on every platform:
Duration — a span in whole seconds; seconds/minutes/hours/days build one,
as_seconds/as_minutes/as_hours/as_days read it back. Because a
duration is just an int, `+` and `>` work with no extra machinery
(Duration.minutes(5) + Duration.seconds(30), away > Duration.hours(3)).
Date — a civil day as days-since-1970 (UTC): new/year/month/day/weekday/
is_leap/days_in_month/to_epoch/add_days/diff_days.
DateTime — an instant as seconds-since-1970 (UTC, matching Time.now):
from/date/add/year/month/day/weekday/hour/minute/second.
Time.since(past) = now - past, for offline-progress / "time away" checks.
New selfhost/emit_datetime.ludic (is_/emit_ for the three namespaces, wired
into emit_ns_call + the frag list). The two civil<->epoch conversions are
Howard Hinnant's public-domain proleptic-Gregorian algorithms, emitted once
per program as the @fn_days_from_civil / @fn_civil_from_days prelude and gated
by g_uses_datert; days_in_month is next-month-day-0 (no lookup table). Time
gains `since`. Docs (Duration/Date/DateTime sections, 28 method pages +
time-since), inventory, and LSP hover kept in sync; a registered test checks
component math against hand-computed values. Reseeded; C-free fixpoint holds;
all suites green (26 self-host / 45 regression / 29 tools); check.py,
check-impl.py and validate.py OK.
format/parse, a game-controlled simulated clock, and timezones are tracked
follow-ups; v1 is UTC-only and, on the i32 epoch, valid through 2038.

Implement the Vec.* half of #25 under the proper (de-abbreviated) name
Vector, unblocking it with a self-contained value type instead of waiting
on the full #1 type system.
A Vector is two Q16.16 fixed components (x, y) packed into one i64 — a true
by-value type that lives in a register and never allocates (reuses the new
`long`/i64 support; llty maps `Vector` to i64). Fifteen operations, all
deterministic fixed-point reusing fx_mul/fx_div/fx_lerp and the @fn_fx_*
prelude: make/zero/x/y, add/sub/scale/dot, length/distance/normalize/lerp,
rotate/angle/from_angle.
New selfhost/emit_vector.ludic (wired into emit_ns_call + the frag list),
the `Vector` primitive type in llty and the grammars/LSP/JetBrains tokens,
docs (type-vector + 15 Vector.* pages + section), and a registered test.
Reseeded; C-free fixpoint holds; all suites green (45/25/29); site + check.py OK.

De-abbreviate the two bare fixed-point conversion builtins:
flr(f) -> int -> floor(f) -> int (fixed -> int, flooring)
fx(i) -> fixed -> fixed(i) -> fixed (int -> fixed; mirrors how the
stringify builtin is `string`)
Updates the compiler dispatch, all call sites, the grammars/LSP/JetBrains

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.

Math stays (universally accepted, like int/bool). Renames the dispatch

Finish the unblocked "Math / Ease" half of #25: the fixed-point
transcendentals deferred from #2. Vec.* stays blocked on the vec2 type
in #1.
- Math.exp, Math.log (natural), Math.pow — deterministic Q16.16 via two
new prelude fns in emit_math_prelude: @fn_fx_exp2 (range-reduced 5th-order
Taylor 2^f, then a clamped shift by the integer part) and @fn_fx_log2
(llvm.ctlz for the exponent + an atanh series on (m-1)/(m+1) for the
mantissa). exp=2^(x·log2 e), log=log2(x)·ln2, pow=2^(b·log2 a).
- Ease.elastic — ease-out elastic 2^(-10t)·sin((10t-0.75)·2pi/3)+1.
- Pure integer IR, so bit-identical on every platform. Results must fit the
Q16.16 range (|x| < 32768); larger magnitudes saturate (documented).
Test selfhost/tests/transcend.ludic (registered in the self-host suite) +
docs for all four. Reseeded; the C-free bootstrap fixpoint holds. All suites

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).

- Pipeline diagram stacks vertically with downward arrows on mobile (row on
>=720px) instead of the awkward wrap.
- Tooltip cards now open on CLICK (works on touch too), the card itself is
clickable and opens the symbol's page in a NEW TAB, and an outside click or
Escape closes it. Replaces the hover-only behavior.
- Reference pages get their own nav — Home / API Reference / Source ↗ — instead
of the landing-only Features/Examples/Get started anchors, and now include the
Source link.
- Unify the container width (1120px) across the landing and all reference pages
so the header and content align between them.
- Reword extern/@export FFI docs from "C-ABI" to "native" for consistency with
the site's no-C wording.
Verified in-browser at 375px and 1280px: vertical pipeline, click→card→new-tab,
outside-click close, correct reference nav, aligned container; 158 examples still
compile.

Rebuild the API Reference around one page per symbol and richer, verified content.
Pages & navigation
- One HTML page per symbol (kw-*, type-*, phase-*, screen-*, fn-*, annot-*, op-*)
instead of a single scrolling page; namespace overview pages (ns-screen …
ns-color) and a searchable index (api.html) with client-side fuzzy search.
- Sticky-header scroll offset (scroll-margin) so a jumped-to entry/param/color is
never hidden, plus a flash highlight on the scrolled-to target.
Deep linking in every snippet & example
- Namespace members split: `Screen`→namespace page, `fill_rectangle`→method page;
`Color`→palette page, `Charcoal`→its swatch — separately.
- Named arguments (`width:`) link to that parameter's anchor on the method page.
- Hover any token for a summary card built from the real API data (symbols.json).
Content & coverage
- Full authoritative surface documented from the compiler: every keyword, type,
the 6 phases (Start/Input/FixedUpdate/Update/LateUpdate/Render, each its own
page), all 22 annotations, namespace methods with parameter docs, builtins,
the world_* reflection ABI, networking, operators — 155 symbols.
- Longer, clearer explanations; "model"/"model instance" terminology, not "entity";
descriptive identifiers in every example (Position{column,row}, Velocity{delta_x,
delta_y}, Health{current,maximum}, Player/Enemy) — no Pos/Seg/x/dx.
- Accuracy fixes from compiler ground-truth: world_count() takes no arg,
world_query_next(property, cursor) arg order, event fields bind by name; dropped
`when` and `module` (not in the self-hosted parser).
Tooling
- inventory.json + check.py: coverage guard (every symbol has a page), duplicate-
token guard, and broken-link guard — fail CI so docs can't drift.
- validate.py: compiles every ```ludic example against bin/ludicc (158 compile).
