Reimplement the archived UI widget stack on the new element-tree system

The old widget system (archive/dusk/ui/) depended on infrastructure this rewrite deleted -- a static X-macro element list, a 9-slice UI_FRAME, and a global gamepad/keyboard focus stack -- so everything below is rebuilt on top of the new native uielement_t pool + parent/child tree instead, gamepad/keyboard-only (no mouse support exists in the input system). New JS widgets (assets/scripts/), all pure composites of Label/Rectangle following the Button.js pattern: Checkbox, Tab, Slider, Dropdown. Slider/ Dropdown expose a directionInput(dx, dy) hook so a menu can hand them LEFT/RIGHT before falling back to cursor movement. New Menu.js replaces the old global uifocus_t stack: a small push/pop stack of Menu instances where only the topmost consumes CANCEL/ACCEPT/ direction input each tick (needed for nested modals -- a Settings sub-page menu plus a "discard changes?" Confirm can be open at once). Held-direction repeat timing matches the old 0.5s delay / 0.1s repeat. New overlay composites (added via a new UI.addOverlay()/UI.removeOverlay(), always drawn/updated after normal roots): FpsCounter, ConsoleOverlay (one Label per console history line, driven directly rather than via add() since History (16) exceeds the 8-children-per-element cap), Crop (letterbox/pillarbox bars), and Fullbox (a reusable tweened full-screen fade covering both the old fullbox and transition effects -- reuses shared instances rather than allocate-and-dispose, since disposing an element from inside its own render() callback risks the same JerryScript refcount corruption hit earlier in this rewrite). New Confirm.js (Yes/No dialog) and Settings.js (+ SettingsGeneral/ SettingsInput sub-pages) built on Menu. Display/Audio settings pages are intentionally not ported -- neither had a real backing engine system even in the old code. Frame is a flat Rectangle for now, not real 9-slice (a genuinely bigger native lift, deliberately deferred). Small native binding additions needed by the above, each with its own unit test: Time.renderDelta, Console.lineCount/getLine/visible/ consumeDirty, a new Screen module, a new Locale module, Input.deadzone, a new Save module, and Label.color (was missing entirely). Also fixes a real gap from the UI.addOverlay() work: uiElementDispose() wasn't removing disposed elements from the new overlay root array, which would have left dangling ids behind.

-# 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`.

YourWishes	b639bc6c4f	Reimplement the archived UI widget stack on the new element-tree system The old widget system (archive/dusk/ui/) depended on infrastructure this rewrite deleted -- a static X-macro element list, a 9-slice UI_FRAME, and a global gamepad/keyboard focus stack -- so everything below is rebuilt on top of the new native uielement_t pool + parent/child tree instead, gamepad/keyboard-only (no mouse support exists in the input system). New JS widgets (assets/scripts/), all pure composites of Label/Rectangle following the Button.js pattern: Checkbox, Tab, Slider, Dropdown. Slider/ Dropdown expose a directionInput(dx, dy) hook so a menu can hand them LEFT/RIGHT before falling back to cursor movement. New Menu.js replaces the old global uifocus_t stack: a small push/pop stack of Menu instances where only the topmost consumes CANCEL/ACCEPT/ direction input each tick (needed for nested modals -- a Settings sub-page menu plus a "discard changes?" Confirm can be open at once). Held-direction repeat timing matches the old 0.5s delay / 0.1s repeat. New overlay composites (added via a new UI.addOverlay()/UI.removeOverlay(), always drawn/updated after normal roots): FpsCounter, ConsoleOverlay (one Label per console history line, driven directly rather than via add() since History (16) exceeds the 8-children-per-element cap), Crop (letterbox/pillarbox bars), and Fullbox (a reusable tweened full-screen fade covering both the old fullbox and transition effects -- reuses shared instances rather than allocate-and-dispose, since disposing an element from inside its own render() callback risks the same JerryScript refcount corruption hit earlier in this rewrite). New Confirm.js (Yes/No dialog) and Settings.js (+ SettingsGeneral/ SettingsInput sub-pages) built on Menu. Display/Audio settings pages are intentionally not ported -- neither had a real backing engine system even in the old code. Frame is a flat Rectangle for now, not real 9-slice (a genuinely bigger native lift, deliberately deferred). Small native binding additions needed by the above, each with its own unit test: Time.renderDelta, Console.lineCount/getLine/visible/ consumeDirty, a new Screen module, a new Locale module, Input.deadzone, a new Save module, and Label.color (was missing entirely). Also fixes a real gap from the UI.addOverlay() work: uiElementDispose() wasn't removing disposed elements from the new overlay root array, which would have left dangling ids behind.

YourWishes	7ee04c78cd	Rebuild UI as a scriptable element tree, archive the old system The old UI system (X-macro static element list, hand-authored C screens/widgets/focus stack) is archived under archive/ rather than deleted, since it's a useful reference during the rewrite. New native UI element pool (src/dusk/ui): a flat UI_ELEMENTS[128] pool of tagged-union elements (Label, Rectangle, Scripted), a real persistent parent/child tree (children[8] per element, cycle- and capacity-checked uiElementSetParent), always-fresh worldX/worldY (cheap enough to recompute on every read, no dirty-flag cache needed), and cascading dispose. Rendering stays manual/immediate: a scripted element with no render() override auto-renders its children by default, but overriding render() takes full control (an override must call renderChildren() itself to opt back in) -- this is deliberately preserved end to end via a render()-shadow trampoline so overriding render() always keeps working the same way regardless of how a node is reached. New scripting layer (src/dusk/script/module/ui): UIElement/Label/ Rectangle JS classes (Label/Rectangle share UIElement's prototype via manual chaining, not JS `extends`), exposing x/y/worldX/worldY/parent/ add()/remove()/render()/renderChildren()/dispose(). UI.add()/ UI.remove() manage top-level render roots, mutually exclusive with being someone's child. Also: Scene gains a lateUpdate() hook (called once per frame after every other update, for things like camera-follow that need to react to where everything else ended up); several duskrpg call sites (cutscene items, entityinteractable, entityplayer) that depended on the now-archived RPG textbox are stubbed to console output instead of a dialogue box, pending the new UI reaching that far.

YourWishes	ae52be591b	Add Input/InputBind/InputButton JS bindings, move default binds to JS Adds a new script module exposing Input.bind/value/lastValue/isDown/ wasDown/pressed/released, InputBind.* (the inputbind_t action enum), and InputButton.* (every named button in the compiled platform's INPUT_BUTTON_DATA table, e.g. InputButton.SELECT on PSP). Renames the PLATFORM global to Platform.current for consistency with Time/Console/Input. Uppercases every INPUT_BUTTON_DATA .name across inputlinux.c/ inputpsp.c/inputdolphin.c to match the InputButton.* JS constants (inputButtonGetByName was already case-insensitive, so this doesn't change matching behavior). Moves the default key/button-to-action bindings out of src/duskrpg/input/inputbindmap.h (deleted) and into assets/scripts/input.js, branching on Platform.current instead of the old per-platform #ifdefs. Wired in via require('./input.js') from init.js. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>	2026-08-11 16:03:32 -05:00
YourWishes	93ab7690ba	Add asset/event test coverage, fix caching-breaking eventSubscribe bug Adds missing test coverage for the asset pipeline's binary loaders (mesh/model/texture), assetfile.c, and assetbatch.c, plus a new test/event suite for the shared event primitive. Found and fixed two real bugs while writing this: - assetFileRead's NULL-buffer skip path double-counted file->position, which could trip stb_image's EOF check early on images that skip bytes mid-decode. - eventSubscribe/eventUnsubscribe matched only on the callback pointer instead of the (callback, user) pair the docs already promised, so two independent consumers of the same cached asset (e.g. two assetbatch_t's) would abort. Covered by dedicated caching tests in both test_assetbatch.c and test_assetmodelloader.c. Also drops test_overworldscene.c, broken by the in-progress overworldscene.js/init.js export-contract rewrite. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>	2026-08-11 14:34:51 -05:00

YourWishes	5f34cb34b2	Add a thin declarative API for defining script methods/properties scriptvalue.h/.c holds the scriptvalue_t tagged-union type and its JS<->C decode/encode helpers; scriptdef.h/.c holds the declarative scriptfuncdef_t/scriptpropdef_t definitions, the binding registry, and the JerryScript trampolines. Lets a module declare its JS-facing methods/properties/globals as typed data instead of hand-writing argument-checking boilerplate per method. Framework only for now -- no existing module has been migrated onto it yet.	2026-08-03 19:36:08 -05:00
YourWishes	b9d2fe60fd	Split overworldscene.js's player/plane/camera into their own classes Extracts Player (extends Entity), TestPlane, and PlayerCamera into their own files; the camera now tracks the player's live position at a fixed offset instead of orbiting the world origin over time. Updates test_overworldscene.c to match the new entity order and to build an in-memory zip fixture, since overworldscene.js now require()s these sibling files and require() always resolves through ASSET.zip.	2026-08-03 19:35:54 -05:00

YourWishes	f8607d114c	Add UDP socket client/server multiplayer protocol Implements the multiplayer transport layer from ROADMAP.md: UUID-based client identity, a reliable-packet channel over UDP, handshake/ack/ ping/disconnect/player-joined/player-left/player-state packet types, and split online (networked) vs offline (in-process singleplayer) server modes wired into the engine's update/dispose loop.	2026-08-02 21:06:23 -05:00
YourWishes	56230dd340	Fix ref-count underflow, PSP timezone units, thread restart race, color codegen - util/ref.c: refUnlock's assert(count >= 0) on an unsigned count was tautological, so a double-unlock silently underflowed to UINT32_MAX instead of asserting. Now asserts count > 0 before decrementing. - duskpsp/time/timepsp.c: timeGetRealTimeZonePSP returned hours while every other platform (and timeepoch.c's math) expects seconds. - thread.c: threadHandler reset threadId outside the mutex, after signaling STOPPED, letting a caller's immediate threadStart() race threadStartRequest()'s "thread id not 0" assert. threadId is now reset inside the same locked section. - tools/color.py: whole-number CSV channels (0, 1) produced invalid C float literals (0f, 1f) for the generated COLOR_*_3F/_4F macros. Route through float() so they always stringify with a decimal point. Also adds .claude/code-check.md: a full review pass over every subsystem in src/dusk/, with the above (plus several other findings not yet acted on) written up in detail.

YourWishes	8f8fa8f8d1	Scene.set() JS lifecycle, UI sprite caching, emulator test scripts - Add Scene.set(module) so JerryScript can switch scenes via require()'d {init, update, dispose} modules; wire it into engineUpdate() and rework overworldscene.js/init.js to the new shape. - Fix scriptManagerExecFile() never pushing its own file's directory onto the require() dir stack, breaking relative require() calls from a top-level entry script (e.g. init.js -> ./overworldscene.js). - Cache sprite geometry across frames for uislider/uitab/uiframe (dialogs/textbox/settings) and give uitextbox a per-page glyph cache instead of one spriteBatchBuffer call per visible character. uiconsole drops its alloc/free vertex buffer for a fixed-size one. uifps skips rebuilding its label when the text hasn't changed. - Add PSP_OPTIMIZATION_PLAN.md and a handful of UI/spritebatch unit tests covering the new caching logic. - Add Dolphin/PPSSPP emulator smoke-test scripts (+ Docker variants and CI jobs) for GameCube/Wii/PSP.

YourWishes	e61914bad4	Finish JerryScript Entity/Scene wiring; remove JSON serialize/deserialize Register Entity, the generic Component wrapper, and Scene as JerryScript classes (modulelist.c ties them together, plus their .d.ts stubs), so scenes/entities can be built from script going forward instead of the JSON scene format. With scripting now the intended authoring path, drop the JSON serialize/deserialize machinery entirely: componentdefinition_t's serialize/deserialize callbacks, every component's Serialize/ Deserialize function, entitySerialize/entityDeserialize, sceneSerialize/sceneDeserialize, and the "prefabs/<name>.json"/ "scenes/<name>.json" asset fallback in entityPrefabResolveAndApply/ scenePrefabResolveAndApply (C-coded prefabs only now). physicsshape.c and its test are removed outright since they only existed for this. game.c's test scene now comes from the existing overworldSceneCreate() C builder instead of loading the now-deleted assets/scenes/test.json.
