The type table lists fixeds (buffer of fixed values) and ptrs (buffer of
pointers) alongside words, but they had no reference pages. Add both, with
compilable examples; coverage inventory updated (types: 10 -> 12).

- 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.

Rewrite both stylesheets mobile-first (base = phone; @media min-width
progressively enhances) and add a responsive nav.
- Hamburger menu on small screens: links collapse into a clean, uniform
dropdown list (plain rows + separators, no out-of-place boxed buttons);
full inline nav with boxed CTA returns at >=720px. Auto-wired for every page.
- Fix horizontal-overflow root causes: min-width:0 on grid/flex code containers,
pre/sig scroll internally, long names wrap (overflow-wrap). 0 page overflow on
every page type at 375px.
- Stack layouts on mobile: single-column hero/features/steps/index grid,
column parameter cards, 2-col color swatches; multi-column returns on wider
screens. Reduced hero/section padding; fluid clamp() headings.
- Hover cards gated to hover-capable devices so a tap just navigates.
- Desktop layout preserved (verified at 1280px: inline nav, 2-col hero, 3-col
features, no regression).
Verified in-browser at 375px and 1280px across landing, API index, item
(method/keyword/annotation/phase), namespace overview, and color pages.

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).

Replace the hardcoded landing page and minimal reference with a generated
documentation site driven by a single source of truth.
- docs/language/**: one file per symbol (93 keywords/types/builtins/namespace
methods/operators/annotations), each with front-matter (id, kind, tokens,
sig, tip) + description + a ```ludic example. Seeded by exploding the former
inline SECTIONS list; these files are now the source of truth.
- docs/site/: site.json (editable hero/features/showcase/messaging, not
hardcoded) + snippets/*.ludic (real programs shown on the landing page).
- tools/docgen/gen.py: generates index.html, api.html, ludic-highlight.js and
symbols.json. The highlighter's symbol tables, hover tips and jump anchors
are GENERATED from the per-symbol files — add a symbol and it is recognized,
tipped and linked in every snippet automatically. Python stdlib only.
- tools/docgen/check.py: verifies the pages contract + that no snippet token
links to a missing reference anchor.
- .forgejo/workflows/docs.yml: rebuilds and publishes to the pages branch on
every push to main touching the docs sources.

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).

Implement the rest of NETWORKING-DESIGN.md (N2–N6) and eliminate every
`.c` file from the repo. clang remains only the LLVM-IR assembler; no C
is compiled anywhere.
Networking (selfhost/emit_net.ludic + parser/emit changes):
- N2 @Sync: per-model serialize/apply + by-kind dispatchers; POD-scalar
compile error and empty-participation warning; selective replication.
- N3 @Owned: @L_owner array + owner/set_owner/is_owner; owners snapshot.
- N4 @ToServer/@ToClients remote events: framed net_send + net_pump re-emit.
- N5 @Server/@Predicted role guards + drivable sim (tick_fixed/tick_render,
entry-owns-the-loop).
- Built-in loopback transport so multiplayer runs with zero foreign code;
extern fn net_send/net_poll still overrides it for a real socket.
- N6 blessed runtime (examples/net_rt.ludic) + end-to-end demo (net_demo).
- Fix: llty("entity") is now i32 (entities are i32 handles), so let e = self().
C elimination:
- Networking + foreign-mod-ABI tests rewritten as self-contained pure-Ludic
programs (examples/net_*, world_*, mod_events, scoped); tests/ removed.
- Reflection ABI exposed to Ludic as world_* builtins (Ludic-to-Ludic modding).
- Formatter rewritten C→Ludic: tools/ludic-tools/fmt.ludic.
- Language server rewritten C→Ludic: tools/ludic-tools/lsp.ludic (lexer, index
parser, cross-file workspace resolver, JSON, all LSP handlers).
- Obsolete migrate_*.c codemods deleted; ludic_syntax.h kept as vocabulary data.
Suites: ./test.sh 44/44, ./tools/test-tools.sh 28/28 (LSP 42/42), fixpoint holds.

Groups B and C of the leftover-primitive cleanup — renames, not new machinery,

The last peek/poke pairs were the same "typed buffer access wearing a C name" as
peek8/peek32, so they become indexing too:
peekf(sc_x, i) -> sc_x[i] (a `fixeds` buffer -> a fixed)
pokep(gc_bmp, s,b) -> gc_bmp[s] = b (a `ptrs` buffer -> a pointer)
str_len(s) -> len(s) (len is polymorphic since 7f; str_len was dead)
Two new element-typed buffers join words: `fixeds` (32-bit fixed) and `ptrs`
(pointer, 8-byte stride). emit_index_addr dispatches on the base type; IR is
byte-identical to the old intrinsics.
The peekf/peekp buffers (ed_x0/ed_x1/ol_x/sc_x fixed coords; gc_bmp/img_px/
tt_data/ui_text pointer arrays) were retyped scope-aware, then the 33 sites
migrated to indexing. Two bugs found via a menu golden diff / a link-time type
error and fixed: the buffer-name regex truncated digit suffixes (ed_x0 -> ed_x),
and the char-literal brace-miscount skipped a few module declarations (same class
as 7j).

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

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

`s[a..b]` is a fresh substring of the bytes [a, b) — the modern, end-based form
of the C-style `substr(s, start, count)`:
substr(src, start, i - start) -> src[start..i]
substr(t, 2, len(t) - 2) -> t[2..len(t)]
substr(src, i, 2) -> src[i..i + 2]
Mechanics: a new E_SLICE postfix (`base[lo..hi]`, distinct from `base[i]`
indexing) lowers to a @fn_str_slice prelude (malloc + copy + terminate), emitted
once into any program that slices. Two reseeds: add the syntax + prelude, then
migrate the 22 substr calls and delete substr. The migrator recognises the
common `count == end - start` shape and emits the clean `s[start..end]` rather
than `s[start..start + (end - start)]`.

Answering your readability point directly: the compiler's own string-building —
left uglier by the 7c `+` migration, e.g. `emit_bind(("load i32, ptr " + ip))` —
now reads as interpolation:
emit_bind(("load i32, ptr " + ip)) -> emit_bind(`load i32, ptr {ip}`)
emit_bind(("icmp eq i32 " + (kv + (", " + itoa(ak)))))
-> emit_bind(`icmp eq i32 {kv}, {itoa(ak)}`)
perr(("assign to unknown " + t.s)) -> perr(`assign to unknown {t.s}`)
164 concat chains across selfhost converted by a tool that flattens the `+` tree,
keeps call/index parens (only grouping parens are rewritten), and converts only
**brace-free** literals — LLVM IR structure strings full of `{`/`}` stay as `+`
rather than becoming awkward `{{`/`}}`. No new language surface; interpolation
already desugars to the same concat.

`len` is now polymorphic — a slice's element count OR a string's byte length —
so the C-style `slen` (strlen) is gone: `slen(name)` -> `len(name)`. emit_len

string branch, then migrate the 19 slen calls and delete slen.

One `print` instead of two C-style names: `print(x)` writes an int OR a string
followed by a newline, dispatching on the operand type (int -> %d, string ->
%s). `print(int)` emits byte-identically to the old print_int, so every existing
call and every smoke-test output is unchanged.
print_str was only ever the raw IR-to-stdout dump in ir_flush (no newline), which
is not "printing a line" — so it now uses file_write to a new file_stdout()
stream, keeping the emitted IR byte-for-byte identical. That frees `print` to
have consistent always-newline semantics.
Two reseeds: (A) add print + str + file_stdout keeping the intrinsics; (B)
migrate the 61 print_int calls to print, ir_flush to file_write(file_stdout()),
and delete print_int/print_str (+ the now-dead @.fmt_str). str(x) (the
interpolation converter from 7d) is now also a documented standalone builtin.

The readable way to build strings, as you noted `{a} {b}` beats `a + " " + b`.
A backtick string embeds any expression in `{…}` and desugars to the Phase-7c
`+` chain, wrapping each hole in `str(...)`:
`hello {name}, n={count + 1}`
== "hello " + name + ", n=" + str(count + 1)
- Lexer: a backtick captures its content raw as TK_INTERP.
- Parser: parse_interp splits literal runs from `{…}` holes (brace-depth aware,
`{{`/`}}` escape to literal braces), re-lexes each hole as a full expression
(save/restore toks/pi like an import), and folds it all into E_BIN(+) nodes —
so no new AST or runtime beyond the existing concat.
- str(x): a string passes through; int/bool/fixed convert via a small emitted
@fn_int_str prelude (digits from the end of a buffer, '-' for negatives),
emitted once into any program that uses it.
examples/strings.ludic gains interpolation cases (now prints 1..7); the smoke
covers it. Grammar + ludic_syntax.h tokenize backtick strings (holes highlighted

Strings are values now: `a + b` concatenates and `a == b` / `a != b` compare by
content, replacing the 605 `sconcat(...)` / `streq(...)` calls that made the
compiler read like C.
streq(name, "let") -> name == "let"
sconcat("load ", reg) -> "load " + reg
sconcat(a, sconcat(b, c)) -> a + b + c
Implementation: emit_bin gains a string path. Strings are pointer-typed, so any
`+` with a pointer operand concatenates and `==`/`!=` between pointers compares
content — except when one side is the `null` literal, which stays a pointer
identity test (the only two kinds of pointer `==` in the codebase). Both call a
small hand-written IR prelude, @fn_str_eq / @fn_str_concat, emitted once into any
program that uses string ops (so it works for tools, games and the compiler with
no runtime-splice dependency and no duplicate symbols).
Delivered as two reseeds: (A) add the operators + prelude with the full
pointer-aware dispatch, keeping streq/sconcat; (B) migrate every call site
(354 lines, via a string-literal-safe balanced-paren script that leaves the
function definitions alone) and delete streq/sconcat. examples/strings.ludic +
a test.sh smoke (prints 1 2 3 4 5) guard it.

`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)

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.

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.

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.

`struct` and `property` had identical syntax and differed only in semantics, so
they are now one keyword: `property`. How a property is stored follows from how
it is used —
- listed in a `model` or attached by `spawn` -> an ECS component, kept in the
engine's per-entity @S_/@H_ arrays and bound in queries (as before);
- constructed with `new` -> a heap record with reference
semantics (what `struct` used to be).
A program that declares only `property` records and functions — no `model`, no
`handler` — is not an ECS program: it gets record layouts and `new`, but no
entity storage, allocator, snapshot, or runtime splice. This is exactly the
shape of the Ludic compiler itself, whose Node/Tok/Buf/Val are now `property`.
Mechanics:
- record layout (%Cmp_) now always emitted in the header (emit_head), so `new`
works with or without the ECS; the per-entity arrays stay in
emit_ecs_storage. %Str_ is gone — one layout prefix.
- has_ecs() is now `has_systems() or has_models()`, not "any component"; a
property alone no longer drags in the ECS runtime. Added has_models().
- emit_new / member access / layout_ty / layout_node collapse onto find_comp.
Dropped struct keyword, parse_struct, find_struct, is_struct_ty, N_STRUCT
emission (the const stays at kind 0, the default node kind).
Migration done as two reseeds (the old compiler treats any component as ECS, so
it cannot see `property` records in the compiler source until has_ecs is fixed):
A) teach the compiler property-as-record + fix has_ecs, keeping `struct`;
B) migrate the compiler's own records to `property` and remove `struct`.
selfhost/tests/structs.ludic migrated (still prints 7 9 109 2 42). Vocabulary
drops `struct` from DECL (ludic_syntax.h, grammar, LudicTokens.kt). LANGUAGE.md
"Records" section rewritten. Reseeded (21613 lines); C-free fixpoint holds;
goldens identical; 17/17; vocab + doc-fences clean.

The handler-signature `query (vars) [terms] where …` clause and the
`reads`/`writes` clauses overlapped the `@Queries` annotation (and each other):
two ways to attach a query to a handler. Consolidated on the decorator.
- parse_system no longer parses `query`/`reads`/`writes` clauses; it keeps the
postfix `@anno(...)` channel and `phase`. A handler's query is the prefix
`@Queries(these: [...], on: Model)` annotation. Data-access hints are now
`@Reads(...)`/`@Writes(...)` — absorbed by the generic annotation skipper,
same parse-and-reserve status the old clauses had.
- The inline `for (…) in query […] where …` statement is unchanged and still
covers cross-property constraints / multiple kind filters. `query` stays a
keyword there (now dispatched via is_id so the vocabulary check sees it).
examples/hello.ludic and examples/qdecl.ludic migrated to `@Queries` (qdecl now
demonstrates a per-property constraint + `on:` tag); outputs unchanged
(4 4 10 3 / 0 3 -2). LANGUAGE.md handler sections rewritten. Vocabulary: drop
`reads`/`writes` from CLAUSE (ludic_syntax.h, grammar, LudicTokens.kt).
Reseeded (21931 lines); C-free fixpoint holds; goldens identical; 17/17;
vocab + doc-fences clean.

Cohesion audit found two keywords that are pure duplicates:
- `when c { }` produced a byte-identical S_IF to an else-less `if c { }`
(no distinguishing flag) — so it was a second spelling of the same node.
- `enter Name` produced identical codegen to `become Name`: it set an
`ival` flag that emit_become never reads.
Both removed from the parser. `if` already parses with an optional `else`, so
nothing is lost. examples/scenes.ludic (an uncompiled design sketch) and the
LANGUAGE.md scenes section now use `become Name` for scene transitions.
Vocabulary synced (ludic_syntax.h, TextMate grammar, LudicTokens.kt);
check-vocabulary clean. Reseeded (22148 lines); C-free fixpoint holds;
goldens identical; 17/17.

Three enable/disable statement scopes, each a reversible flag flip:
- `disable P on e` / `enable P on e` — one property on one entity. Clears
the has-flag so queries stop matching; field data persists in storage, so
enable restores it untouched. @OnDisable(P)/@OnEnable(P) handler hooks run
at the toggle point with the property bound by name.
- `disable Model` / `enable Model` — @ME_<Model> global flag; the model's
entities drop out of every query while disabled.
- `disable Handler` / `enable Handler` — @HE_<Handler> global flag; the
handler stops being called each phase while disabled.
Nothing is copied or freed — each toggle is one global store or one has-flag
store. Reduces entirely to existing ECS machinery (has-flags, kind filter,
per-phase call guards), so the data-oriented model is untouched.
New AST node S_TOGGLE; emit_toggle lowers it. Query {Model} filter now ANDs
@ME_; phase calls now guard on @HE_. Parser gains enable/disable statements
and @OnEnable/@OnDisable annotations.
Vocabulary: `on` promoted from RESERVED to CLAUSE (parser now dispatches on
it); enable/disable added as STMT keywords — synced across ludic_syntax.h,
the TextMate grammar, and LudicTokens.kt (check-vocabulary.py clean).
examples/toggle.ludic demonstrates all three scopes (prints 6 0 7 1 0);
test.sh smoke asserts it. Reseeded; C-free fixpoint holds; goldens identical.
Also: stop tracking tools/.idea/ (gitignored).

The full game/entity/property lifecycle as @-hooks, symmetric with @OnSpawn.
test.sh 16/16, C-free fixpoint holds, goldens byte-identical.

Adds the rest of the game/entity/property lifecycle as @-hooks, each firing at
one timeline moment and reducing to ordinary code:
- @OnStart / @OnQuit (program): @OnStart aliases the Start phase; @OnQuit runs in
the frame loop's done: block, after the loop stops and before teardown.
- @OnDespawn(Model) (entity): a destructor. Despawn doesn't statically know the
entity's model, so hooks compile to @on_despawn_<Model>(entity) functions and
emit_despawn dispatches on @L_kind. Symmetric with @OnSpawn.
- @OnAttach(Property): fires in emit_init_component once a property is attached
and seeded, with the property bound by name.
Registries + parsing mirror @OnSpawn. examples/lifecycle.ludic narrates the whole
timeline (output 1 700 50 950 2). Behaviour-preserving (goldens byte-identical,
despawn users unaffected when no hooks registered); test.sh 16/16, fixpoint holds.
Deferred: @OnDetach (per-property runtime dispatch) and scene @OnEnter/@OnExit
(need scene support in the compiler).
