refactor(monorepo): reorganización lógica + renames + SDDs + split CHANGELOG
Reorganización física de crates/: - core/ (mezclaba 6 propósitos) se divide en protocol/, init/, runtime/, compat/ - shared/ (3 crates) se redistribuye en protocol/ e init/ - lapaloma (sub-módulo de ui_engine) se promueve a modules/pineal/ Renames de proyectos: - shipote → shuma (runtime de sandboxes) - nouser → akasha (explorador de Mónadas) - yahweh → nahual (motor GPUI, antes ui_engine/) - lapaloma → pineal (data-viz agnóstica) Fraccionamiento UI → core agnóstico: - vista-core (DeckState + snap, 175 LOC, 5 tests verdes) - barra-core (Task + render_html + sanitize, 90 LOC, 5 tests verdes) - vista-web y barra-web ahora son thin DOM bindings Documentación nueva: - 16 SDDs por subdirectorio (≤80 LOC c/u): protocol/init/runtime/compat + 10 módulos + apps/ - docs/STATUS.md con cifras reales por proyecto - docs/ROADMAP.md con plan a finalización (6 hitos, ~6-8 semanas) - CHANGELOG.md particionado en docs/changelog/<proyecto>.md (7 buckets) Automatización: - scripts/reorg.py — script idempotente que: git mv directorios, renombra package names, recomputa path = refs, reescribe imports rust, actualiza workspace Cargo.toml. Soporta --dry-run. - scripts/split-changelog.py — particiona CHANGELOG por componente. Validación: - cargo check --workspace pasa (124 crates + 2 nuevos cores). - 10 tests adicionales (5 en vista-core + 5 en barra-core) verdes. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

# modules/vista/ — Deck horizontal swipe (PageView)
|
||||
|
||||
**Propósito.** Carousel/PageView estilo Flutter: gesto horizontal con
|
||||
snap a página, distinción horizontal vs vertical, soporte mouse +
|
||||
touch + pointer events. Lógica separada del binding DOM.
|
||||
|
||||
## Crates
|
||||
|
||||
| crate | tipo | rol |
|
||||
| ------------- | ---- | --------------------------------------------------------- |
|
||||
| `vista-core` | lib | `DeckState` agnóstico: pointer_down/move/end → outcomes |
|
||||
| `vista-web` | lib | Binding DOM sobre `<strip>`: traduce eventos + aplica CSS |
|
||||
|
||||
## Dependencias
|
||||
|
||||
- `vista-core`: sin deps externas. Pura state machine.
|
||||
- `vista-web` ← `vista-core`, `wasm-bindgen`, `web-sys` (PointerEvent).
|
||||
|
||||
## API agnóstica (vista-core)
|
||||
|
||||
```rust
|
||||
let mut deck = DeckState::new();
|
||||
deck.pointer_down(x, y, pointer_id, viewport_width);
|
||||
match deck.pointer_move(x, y) {
|
||||
DragOutcome::StartHorizontal { pointer_id } => capture_pointer(),
|
||||
DragOutcome::DragOffset(px) => apply_translate(px),
|
||||
DragOutcome::CancelVertical => yield_to_scroll(),
|
||||
DragOutcome::Idle => {}
|
||||
}
|
||||
if let Some(r) = deck.pointer_end(offset, width, n_pages) {
|
||||
apply_translate(r.offset_px);
|
||||
if r.changed { notify(r.target_index); }
|
||||
}
|
||||
```
|
||||
|
||||
## Estado
|
||||
|
||||
vista-core: 5 tests verdes (drag decision + snap + clamp + goto).
|
||||
vista-web: binding DOM intacto, ahora delega toda la lógica a core.
|
||||
LOC 530 (core 175 + web 355). Reutilizable en backends no-web.
