 ### Known Issues & Technical Debt
 
 1. **gif.h cannot be included twice**: Functions are not `static` or `inline`, causing multiple definition errors. Text class uses `extern` forward declarations as workaround
-2. **Cheats are broken (`reviu`, `alone`, `obert`)**: `JI_CheatActivated` in [jinput.cpp:46](source/core/jail/jinput.cpp#L46) compares `SDL_Scancode` values (e.g. `SDL_SCANCODE_R`=21) against ASCII chars (`'r'`=114). They never match. Regression from SDL3 migration. **Now fixable** — scheduled for Phase 1 of modernization since jail is no longer off-limits.
+2. ~~**Cheats are broken (`reviu`, `alone`, `obert`)**~~: Fixed. `JI_moveCheats` tradueix `SDL_Scancode` → ASCII via `scancode_to_ascii` abans de ficar-los al buffer ([jinput.cpp:32-37, 55-61](source/core/jail/jinput.cpp#L32-L61)), i `JI_CheatActivated` compara ASCII amb ASCII.
 3. **No sound effects in game**: Game code never calls `JA_PlaySound*`/`JA_LoadSound` — only music via `JA_PlayMusic`/`JA_FadeOutMusic`. The SONS and VOL SONS menu items control volume of an empty channel pool. Infrastructure ready for future SFX.
-4. **Raw `malloc`/`free` in gameplay structs**: `Sprite`/`Entitat` use `malloc` for `Frame[]` and `Animacio[]`; `jfile.cpp` uses a global `scratch[255]` buffer (UB under concurrent calls); `jail_audio.cpp` mixes `new`/`malloc`/`SDL_malloc`. Scheduled for Phase 1 (RAII pass).
-5. **Blocking loops in cinematics and fades**: `ModuleSequence::doIntro()` has 15+ `while(!JG_ShouldUpdate())` spin-waits; `JD8_FadeOut`/`JD8_FadeToPal` run 32 internal iterations calling `JD8_Flip`. Incompatible with `SDL_AppIterate`. Scheduled for Phase 2 (state-machine refactor).
+4. ~~**Raw `malloc`/`free` in gameplay structs**~~: Majoritàriament arreglat. `Sprite`/`Entitat` usen `std::vector<Frame>` i `std::vector<Animacio>` ([sprite.hpp](source/game/sprite.hpp)). `jfile.cpp` ja no té el global `scratch[255]` (substituït per `thread_local std::string`). L'API `file_getfilebuffer` (que tornava raw `char*` amb `malloc`) s'ha substituït per `file_readfile` que retorna `std::vector<char>` RAII — elimina els leaks silenciosos que hi havia a `JD8_LoadPalette`, `ModuleGame::Go()` i `scenes::playMusic`. Queda `jail_audio.hpp` barrejant `new`/`malloc`/`SDL_malloc` de forma pairada i correcta (no leak), pendent de polir amb `std::unique_ptr` quan toque.
+5. ~~**Blocking loops in cinematics and fades**~~: Fixed. La migració completa de `ModuleSequence::do*()` a la capa `scenes::` (Steps 1–9) ha eliminat tots els `while(!JG_ShouldUpdate())` i `wait_frame_or_skip()`. Les cinemàtiques ara són tick-based amb acumuladors ms. `JD8_FadeOut`/`JD8_FadeToPal` encara tenen el seu bucle intern de 32 passos (usat per a transicions fora d'escena com al final de `ModuleGame`); el wrapper tick-based `scenes::PaletteFade` el consumeix un pas per tick quan es crida des d'una escena.
 6. ~~**`SDL_AddTimer` in audio**~~: Fixed in Phase 3. `jail_audio` is now a header-only `inline` module (single `.cpp` stub only hosts the `stb_vorbis` implementation to avoid multiple definitions). Music uses true streaming via `stb_vorbis_open_memory` + `JA_PumpMusic` with a 0.5s low-water-mark instead of decoding the whole OGG into RAM. Mixing/fade update runs manually via `JA_Update()` called once per frame from `Director::run()`. Ported from the `jaildoctors_dilemma` codebase.
 7. ~~**Game thread + `publishFrame` mutex/cv**~~: Fixed in Phase 4+5. Replaced by a cooperative `GameFiber` (ucontext on POSIX, Fibers API on Windows). `JD8_Flip()` calls `GameFiber::yield()`, Director calls `GameFiber::resume()` once per frame. Zero threads, zero mutexes. Emscripten fiber backend still pending for Phase 7.
