+# Dusk — Claude Code rules
+
+## File headers
+Every C, H, and JS file starts with:
+
+```c
+/**
+ * Copyright (c) 2026 Dominic Masters
+ *
+ * This software is released under the MIT License.
+ * https://opensource.org/licenses/MIT
+ */
+```
+
+JS files use `//` comment style instead.
+
+---
+
+## C conventions
+
+### Types
+Always use the project-defined aliases instead of bare C primitives:
+
+| Use       | Not          |
+|-----------|--------------|
+| `bool_t`  | `bool`       |
+| `int_t`   | `int`        |
+| `float_t` | `float`      |
+| `char_t`  | `char`       |
+
+Use `uint8_t`, `uint16_t`, `int32_t`, etc. for fixed-width integers.
+All struct and enum types end in `_t` (`animation_t`, `errorret_t`, …).
+
+### Naming
+- **Functions** — snake_case, prefixed with their module:
+  `assetLock()`, `entityPositionInit()`, `moduleAssetBatchCtor()`
+- **Struct fields** — camelCase: `keyframeCount`, `localPosition`
+- **Macros / constants** — UPPER_SNAKE_CASE:
+  `ENTITY_ID_INVALID`, `ERROR_OK`, `COMPONENT_TYPE_COUNT`
+- **Files** — snake_case matching the primary type: `entityposition.c`,
+  `moduleassetbatch.c`
+
+### Header files (`.h`)
+- Use `#pragma once` — no include guards.
+- Declare every public function, `#define`, and `extern` global.
+- Write a JSDoc block (`/** … */`) above every declaration explaining
+  purpose, `@param`s, and `@returns`.
+- Only include headers that the `.h` file itself strictly requires for
+  the types it exposes. Move everything else to the `.c` file.
+  Do not use forward declarations as a workaround — use the real
+  include in the `.c` file instead.
+
+### Implementation files (`.c`)
+- Contain function bodies only; no declarations.
+- Pull in whatever additional includes the implementation needs.
+- Do not use `static` or `inline` on **functions**. Every function,
+  including internal helpers, must be declared in the matching `.h` and
+  defined in the `.c` file. Internal helpers belong near the bottom of
+  the `.c` file, not at the top with a `static` qualifier.
+  `static` and `inline` on functions are only appropriate when the
+  function body is written directly inside a `.h` file.
+  `static` on **variables** (file-scope state) is fine and expected.
+
+### Formatting
+- Hard-wrap all lines at **80 characters**.
+
+### Error handling
+Return `errorret_t` from fallible functions. Use these macros:
+
+```c
+errorOk();                    // return success
+errorThrow("msg %d", val);    // return failure with message
+errorChain(someCall());       // propagate failure, continue on success
+errorIsOk(ret) / errorIsNotOk(ret)  // test a result
+errorCatch(ret);              // handle + free an error
+```
+
+Never return raw error codes or use `errno` for in-engine errors.
+
+### Memory
+Use the project allocator — never raw `malloc`/`free`:
+
+```c
+memoryAllocate(size)          // allocate
+memoryFree(ptr)               // free
+memoryZero(dest, size)        // zero a block
+memoryCopy(dest, src, size)   // copy
+```
+
+### Asserts
+Prefer specific assert macros over bare `assert()`:
+
+```c
+assertNotNull(ptr, "msg");
+assertTrue(cond, "msg");
+assertFalse(cond, "msg");
+assertUnreachable("msg");
+assertIsMainThread("msg");
+```
+
+---
+
+## Build system
+Each subdirectory has its own `CMakeLists.txt` that adds sources with:
+
+```cmake
+target_sources(${DUSK_LIBRARY_TARGET_NAME}
+  PUBLIC
+    myfile.c
+)
+```
+
+Never add source files to the root `CMakeLists.txt` directly.
+
+---
+
+## Platform support
+
+### Targets
+Set `DUSK_TARGET_SYSTEM` at CMake configure time to select a platform:
+
+| `DUSK_TARGET_SYSTEM` | Macro defined     | Platform         |
+|----------------------|-------------------|------------------|
+| `linux`              | `DUSK_LINUX`      | Linux desktop    |
+| `knulli`             | `DUSK_KNULLI`     | Knulli (handheld)|
+| `psp`                | `DUSK_PSP`        | Sony PSP         |
+| `vita`               | `DUSK_VITA`       | PlayStation Vita |
+| `gamecube`           | `DUSK_GAMECUBE`   | Nintendo GameCube|
+| `wii`                | `DUSK_WII`        | Nintendo Wii     |
+
+### Layer structure
+```
+src/dusk/          core, platform-agnostic game logic
+src/duskgl/        OpenGL abstraction (Linux, Knulli, PSP, Vita)
+src/dusksdl2/      SDL2 window + input (Linux, Knulli, PSP, Vita)
+src/dusklinux/     Linux + Knulli platform impl
+src/duskpsp/       PSP platform impl
+src/duskvita/      Vita platform impl
+src/duskdolphin/   GameCube / Wii platform impl (no SDL2/OpenGL)
+```
+
+Dolphin is the only target that bypasses SDL2 and OpenGL entirely —
+it uses native GameCube/Wii rendering and input APIs.
+
+### Platform guards
+Use the compile-time macros for platform-specific code:
+
+```c
+#ifdef DUSK_PSP
+  // PSP-only path
+#elif defined(DUSK_GAMECUBE) || defined(DUSK_WII)
+  // GameCube / Wii path
+#else
+  // Generic / Linux fallback
+#endif
+```
+
+Additional capability macros set per-target:
+`DUSK_SDL2`, `DUSK_OPENGL`, `DUSK_OPENGL_ES`, `DUSK_OPENGL_LEGACY`,
+`DUSK_INPUT_GAMEPAD`, `DUSK_INPUT_KEYBOARD`, `DUSK_INPUT_POINTER`,
+`DUSK_PLATFORM_ENDIAN_BIG` / `DUSK_PLATFORM_ENDIAN_LITTLE`.
+
+### Abstraction pattern
+Platform-specific implementations are wired in via `#define` macros in
+each platform's `displayplatform.h` / `inputplatform.h` etc., which
+the core calls through. Functions that a platform does not support are
+simply left undefined — the core guards calls with `#ifdef`.
+
+### Adding platform-specific code
+- Put it under `src/dusk<platform>/` in the matching subsystem folder.
+- Gate any core call-site with the appropriate `#ifdef DUSK_<PLATFORM>`
+  or capability macro.
+- Keep the `src/dusk/` core free of platform ifdefs — delegate through
+  the platform header macros instead.
+
+---
+
+## Adding a new asset loader type
+1. Add an enum value to `assetloadertype_t` (before `_COUNT`) in
+   `src/dusk/asset/loader/assetloader.h`.
+2. Add fields to the input/loading/output unions in `assetloader.h`.
+3. Implement `assetXxxLoaderSync`, `assetXxxLoaderAsync`, and
+   `assetXxxDispose` in a new `src/dusk/asset/loader/xxx/` directory.
+4. Register the three callbacks in `ASSET_LOADER_CALLBACKS[]` in
+   `src/dusk/asset/loader/assetloader.c`.
+5. If user-facing, create a JS module (see below) and a `.d.ts` file.
+
+---
+
+## Adding a new entity component
+1. Create `src/dusk/entity/component/<category>/entityMyComp.h/.c` with
+   struct `entityMyComp_t`, `entityMyCompInit()`, and optionally
+   `entityMyCompDispose()`.
+2. Add the include to `src/dusk/entity/componentlist.h` header block.
+3. Add a row to `src/dusk/entity/componentlist.h`:
+   ```c
+   X(MYCOMP, entityMyComp_t, myComp, entityMyCompInit, NULL, NULL)
+   ```
+   This auto-generates the enum, union field, and definition entry.
+4. If JS-facing, create the script module and `.d.ts` (see below).
+
+---
+
+## Adding a new script (JS) module
+1. Create `src/dusk/script/module/<category>/moduleMyMod.h/.c`.
+   - Declare `extern scriptproto_t MODULE_MYMOD_PROTO;` in the header.
+   - Use `moduleBaseFunction(name)` to define JS-callable functions.
+   - Register props/funcs in `moduleMyModInit()` with
+     `scriptProtoDefineProp` / `scriptProtoDefineFunc` /
+     `scriptProtoDefineStaticFunc`.
+2. `#include` the header in
+   `src/dusk/script/module/modulelist.c` and call
+   `moduleMyModInit()` in `moduleListInit()` (and `Dispose` in
+   `moduleListDispose()`).
+3. For component modules also register in
+   `src/dusk/script/module/entity/component/modulecomponentlist.c`
+   so `entity.add()` returns the typed wrapper.
+4. Create `types/<category>/mymod.d.ts` and add a
+   `/// <reference path="..." />` line to `types/index.d.ts`.
+
+---
+
+## Script module type declarations
+Whenever a `src/dusk/script/module/**/*.c` file is created or modified,
+check whether the corresponding `types/**/*.d.ts` needs updating and
+apply any changes before finishing the task.
+
+---
+
+## JavaScript (asset scripts)
+- Use `var` for module-level state; `const` for values that never
+  change.
+- Always use semicolons.
+- Scene objects are plain objects (`var scene = {}`) with assigned
+  methods.
+- Export via `module.exports = scene`.
+- Async scene init should use `async function` and `await`.
+
+---
+
+## Coding style
+
+### ASCII only
+Source files (`.c`, `.h`, `.js`) must contain only ASCII characters (U+0000–U+007F).
+Non-ASCII characters are banned even in comments and string literals.
+Use ASCII-only substitutes instead:
+- `--` or `-` instead of `—` (em dash)
+- `->` instead of `→` (arrow)
+- `x` or `*` instead of `×` (multiplication)
+
+Only non-script asset files (e.g. `.po` locale files) may contain non-ASCII text.
+
+### Indentation
+2 spaces. No tabs.
+
+### Keyword and operator spacing
+No space between a keyword or function name and its opening parenthesis:
+
+```c
+if(!ptr) return;
+for(uint8_t i = 0; i < count; i++) {
+while(entry->state != DONE) {
+switch(type) {
+sizeof(assetbatch_t)
+memoryZero(ptr, size)
+```
+
+Spaces around all binary operators and after every comma:
+
+```c
+pos->flags |= ENTITY_POSITION_FLAG_WORLD_DIRTY;
+(size_t)end - (size_t)start
+foo(a, b, c)
+```
+
+### Braces
+Opening brace on the **same line** as the statement (K&R style) for all
+constructs — functions, `if`, `else`, `for`, `while`, `switch`:
+
+```c
+void assetEntryLock(assetentry_t *entry) {
+  ...
+}
+
+if(dirty) {
+  ...
+} else {
+  ...
+}
+```
+
+### Guard returns
+Short guards go on one line with no braces:
+
+```c
+if(!ptr) return;
+if(!b || !b->batch) return jerry_undefined();
+if(!(flags & DIRTY)) return;
+```
+
+### Blank lines
+- One blank line between functions; no blank line at the start or end of
+  a function body.
+- One blank line between logical blocks inside a function body.
+- No trailing blank lines at the end of a file.
+
+### Pointer placement
+`*` is attached to the variable name, not the type:
+
+```c
+assetentry_t *entry
+const char_t *name
+void *ptr
+uint8_t *d = (uint8_t *)dest;
+```
+
+### Casts
+Space between cast and operand:
+
+```c
+(assetbatch_t *)user
+(uint8_t *)dest
+(textureformat_t)v
+```
+
+### Return
+No parentheses around the return value:
+
+```c
+return ptr;
+return MEMORY_POINTERS_IN_USE;
+```
+
+### switch / case
+`case` indented 2 spaces from `switch`; body indented 2 more from `case`:
+
+```c
+switch(type) {
+  case ASSET_LOADER_TYPE_TEXTURE:
+    descs[i].input.texture = (textureformat_t)v;
+    break;
+  default:
+    break;
+}
+```
+
+### Multi-line function signatures
+When parameters don't fit on one line, put each on its own line indented
+2 spaces; the closing `) {` (definition) or `);` (declaration) goes on
+its own line at column 0:
+
+```c
+void assetEntryInit(
+  assetentry_t *entry,
+  const char_t *name,
+  const assetloadertype_t type,
+  assetloaderinput_t *input
+) {
+
+errorret_t memoryCompare(
+  const void *a,
+  const void *b,
+  const size_t size
+);
+```
+
+### Structs and enums
+Anonymous inner struct or enum with a `typedef`, `_t` suffix, closing
+brace and name on the same line:
+
+```c
+typedef struct {
+  errorcode_t code;
+  char_t *message;
+} errorstate_t;
+
+typedef enum {
+  ASSET_LOADER_TYPE_NULL,
+  ASSET_LOADER_TYPE_COUNT
+} assetloadertype_t;
+```
+
+### Designated initialisers
+Spaces inside braces; `.field = value`:
+
+```c
+jsassetentry_t e = { .entry = entry };
+assetbatchloadedpend_t init = { .batch = batch };
+```
+
+### Ternary operator
+Spaces around `?` and `:`:
+
+```c
+const float val = psx > 0.0f ? pt[0][0] / psx : 0.0f;
+```
+
+### const placement
+`const` before the type, `*` attached to the variable:
+
+```c
+const char_t *name
+const void *src
+const size_t size
+```
+
+### Comments in `.c` files
+- Do not use section dividers (`/* ---- ... ---- */`). Just let the
+  functions follow one another with a single blank line between them.
+- Multi-line explanatory comments inside function bodies use `//` lines:
+  ```c
+  // Script modules are freed; orphaned JS wrapper objects now get GC'd
+  // so their finalizers fire before assetDispose() checks ref counts.
+  jerry_heap_gc(JERRY_GC_PRESSURE_HIGH);
+  ```
+- Do not use `/* */` for inline or inline-block comments inside `.c`
+  function bodies.
+
+### Comments in `.h` files
+Every public declaration gets a Javadoc block (`/** … */`) with
+`@param` and `@returns` where relevant. Keep it on the lines immediately
+above the declaration with no blank line in between.
+
+---
+
+## Color system
+
+Colors are defined in `src/dusk/display/color.csv` and code-generated
+into a `color.h` header by `tools/color/csv/__main__.py`.
+
+Each row in the CSV has `name,r,g,b,a` with channel values in `[0.0, 1.0]`.
+The script emits four `#define` variants per color plus a bare alias:
+
+```
+COLOR_<NAME>_4B   color4b(r8, g8, b8, a8)   // default alias target
+COLOR_<NAME>_3B   color3b(r8, g8, b8)
+COLOR_<NAME>_3F   color3f(rf, gf, bf)
+COLOR_<NAME>_4F   color4f(rf, gf, bf, af)
+COLOR_<NAME>      COLOR_<NAME>_4B
+```
+
+`color_t` is `color4b_t` (four `uint8_t` channels).
+
+To add a new color, append a row to `color.csv` and rebuild — do not
+hand-edit the generated header.
+
+---
+
+## Tests
+- Tests live in `test/` mirroring `src/dusk/` structure.
+- Use cmocka; include `dusktest.h`.
+- Test functions: `static void test_something(void **state)`.
+- After each test, assert `memoryGetAllocatedCount() == 0` to catch
+  leaks.
+- Build with `-DDUSK_BUILD_TESTS=ON`.
