--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.

- the function that calls every reducer (and the action queue) is written in the program's own
file: in the first action's file it belonged to that module, depended on every module with a
reducer, and joined a game's modules into one 69-module cycle (examples/actions/modules and a
ludic deps case hold it); the state instances, the queue and the reducers make no deps edges
- ludicc --check / ludic build --check lower the program too and write nothing, so the code
writer's refusals are in it: a bind to a function that is gone, an unknown name (and the checker
now refuses fn <missing> itself); rejects bind_missing_fn, unknown_name, registry_count_key
- def R count is refused: its constant would be PREFIX_COUNT, the registry's size
- a file's module, package, trust and numbers-float are tables, and from the check on the lookups
of functions, enums, records, globals and externs are too (tagged enums kept as a list): Maroon
Lake's check-only build went from about 20 s to 7 s including lowering, its IR from about 2
minutes to under 10 s; duplicate declarations are found by table, not a pair of loops
- threads.ludic's pool check gives each call a little work, so a busy machine cannot run them all
on the caller before a worker wakes (it failed one run in three under load)

The parse, the types and the module rules (export, uses, layers, ports,
registries) run and nothing is emitted or linked: about three seconds
on Maroon Lake. In this mode the checker asks vis_check at each
reference it resolves, with a global's initializer and a registry's
entries seen from the files the emitter would use. Reseed.

`ludic help` ended with a section titled "contributing to the toolchain itself",
listing bootstrap, reseed, docs-gen and release tasks. None of that is available
to someone who installed the language — those tasks need the repository — so the
shipped tool was advertising work its user cannot do, in a namespace they have to
read past to find `new` and `run`.
The tasks move to a second program, dev.ludic -> bin/ludic-dev, built from a
checkout and excluded from every release artifact. `ludic` keeps the project and
package commands and nothing else; `ludic dev …` now explains where the tasks
went instead of failing as an unknown command.
What this shook out: the two programs share prelude/build/project/pkg, so the
helpers each had accreted in whichever file first needed them — cc(),
ensure_ludicc, the string functions, title_case, cmd_version — moved to where
both can see them. The argument-shift indirection added for the `dev` namespace
is gone with the namespace, so commands read argv directly again.
`ludic-dev test` asserts the split rather than trusting it: the staged install
must build a project, and `ludic dev build` there must fail while naming
ludic-dev. install.sh keeps building older tags, whose bootstrap goes through
main.ludic.

Getting started meant cloning the repository, bootstrapping a compiler and
learning a task runner called `x`. That is a contributor's workflow handed to
everyone who wants to try the language.
Installing is now one command:
curl -fsSL https://workshopsoft.pages.workshopsoft.io/ludic/install.sh | sh
install.sh puts a complete toolchain — compiler, CLI, engine runtime, bundled
ludic.* packages, formatter, language server — in ~/.ludic and adds it to PATH.
Prebuilt artifacts are checksum-verified; where a platform has none, or the
release predates this layout, it bootstraps from the compiler's own IR seed with
clang. The docs site publishes the script beside the pages that quote it, so the
page and the script can never come from different releases.
`x` becomes `ludic`, and the surface splits by audience. A user of the language
sees `new`, `run`, `build`, `test`, `add`, `fmt`, `lsp`, `doctor`, `upgrade`;
`ludic new` scaffolds a project that builds and plays as it stands. Everything
the toolchain repo needs moved under `ludic dev` — build, test, reseed,
bootstrap-cfree, docs-gen, release — unchanged apart from the namespace. Those
tasks read arguments one position further along, so dispatch_dev sets a shift
and commands use arg_n()/arg_total() rather than each knowing its own depth.
Release artifacts become complete install roots (bin/ beside runtime/, packages/
and VERSION) rather than bare binaries, which is what the installer unpacks.
`ludic dev test` asserts the whole shape: it stages an install, puts it on PATH
with no LUDIC_HOME, and runs new -> build -> test through it.

bin/ is gitignored and not checked in, so the first command in README.md,
COMPILING.md, CONTRIBUTING.md, tools/x/main.ludic and on the site —
clang selfhost/ludicc.seed.ll -o bin/ludicc && ...
failed on a clean checkout with `ld: open() failed, errno=2 for 'bin/ludicc'`.
Verified against a fresh clone. Every copy now leads with `mkdir -p bin`, which
is what the CI workflows had been doing all along.

- LANGUAGE.md: real diagnostic format, list literals, Font.load / Ui.*
(no `reg`/`set_reg`, no `/Handler/Library` typo), `extern function`,
existing example links, Input.key(); builtins table trimmed to what exists
- COMPILING.md: pipeline names selfhost/ (not compiler/*.c), `program`
instead of game/module, all thirteen win_* entry points by group
- README.md: the window seam is not "five" functions
- CONTRIBUTING.md: docs are checked with `x docs-gen` / `x docs-check`
- docs/language: kw-ui and fn-ui_build use the namespaced API;
@ClearColor documents constant expressions; examples/README lists
operators.ludic

The repository root carried 11 large Markdown files (~330 KB); most were
long-lived design records rather than things a newcomer needs on first
contact, which buried the README and mixed "how to use Ludic" with "how we
decided to build it."
Move the design/roadmap docs to the Forgejo wiki (now enabled and
populated): Events, Networking, Scenes, Lifecycle, Mobile and
Syntax-redesign design records, the Bootstrap deep-dive and the Luanti
roadmap, under a Home index + sidebar. Each page had its selfhost/ source
links corrected for the #29 reorg and every repo-relative link rewritten to
an absolute URL on main so it resolves from the wiki.
All eight were current, actively-maintained records, so none were dropped.
The root now holds README.md plus the two user-facing references,
LANGUAGE.md and COMPILING.md; the README links to the wiki, and the
remaining references in LANGUAGE.md / COMPILING.md / examples/README.md and
the emit_net.ludic header comment point at the wiki pages. The emit_net.ludic
change is a comment only — the seed stays byte-identical and bootstrap-cfree
+ the full suite (56) stay green.
Closes#26

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 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).

@Queries(these: [Prop{constraint}, ...], on: Model) on a handler desugars to the
existing S_QUERY loop: each property binds by its own name, a Prop{...} block
qualifies its bare fields to that property, and on: adds a {Model} tag filter.
Implemented via parse_queries_anno + qualify_fields (parse_game.ludic), wired
into parse_one_decl; @Handles parses on the program (documentation).
examples/annotations.ludic demonstrates it (output 3 1 0 0); test.sh 15/15.
Docs: added the Annotations section to LANGUAGE.md and did the vocabulary prose
pass (component->property, archetype->model, system->handler, game->program)
across the docs. check-docs + test-tools green.

edge/pure/export prefix keywords retired; modifiers are now leading @annotations
(@export, @edge, @pure, @deterministic). parse_one_decl collects a leading @anno
run and @export sets the fn export flag; dead edge-dispatch removed from
parse_system. Migrated examples/lib/combat.ludic; old prefixes now rejected.
Behavior-identical: the export flag is parse-only in the self-hosted emitter
(emits @fn_<name> for every fn, never reads the flag), so IR is byte-identical.
Reseeded, fixpoint holds, test.sh 14/14. Docs updated. Phase 3 complete.

Self-hosted compiler (selfhost/*.ludic), runtime, examples, editor tooling,
and docs. Phase 1 of the syntax-redesign cohesion pass has landed:
edge-system fix, signature-query, when-alias, and the documentation truth-pass.
Suite green (14/14), C-free bootstrap fixpoint holds.
