From 9b13e3cf233b958b52323ee51fe044764dd8f28c Mon Sep 17 00:00:00 2001 From: dev Date: Thu, 28 May 2026 13:51:39 +0200 Subject: [PATCH] =?UTF-8?q?feat(words):=20R1=20=E2=80=94=20V2=20architectu?= =?UTF-8?q?re=20proposal=20+=20types-v2=20+=20validator=20+=2050=20tests?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Architectural refactor proposal landed for review. R1 closes the audit + type design + validator phase. V1 stays untouched in parallel. ARCHITECTURE_PROPOSAL.md (~500 lines): - 8 principles signed (P1 content↔design strict, P2 raw values only, P3 renderer translates, P4 runtime state out, P5 framework-neutral engine, P6 single source of truth, P7 sema intents canonical for evaluative vocabulary, P8 per-property entry rules). - D-SEM-1/2/3 + Q1-Q6 all signed with recommendations accepted by user. Notable: CalloutBlock.intent uses SemaIntent canonical (neutral|affirm|fulfill|risk|threat|loss), NOT web admonition vocabulary (warning|info|danger|etc.) — those live as UI labels + Markdown serializer mappings ONLY. engine/types-v2.ts (~320 lines): - WordsDocumentV2 with version '2.0.0'. - BlockBase with optional id (autogen at load) + optional visual sidecar. - BlockVisual with RAW values only (numbers in px, hex color strings). Per-type Pick<> subsets: ParagraphVisual / HeadingVisual / QuoteVisual / CodeVisual / ListVisual / TableVisual / ImageVisual / DividerVisual / CalloutVisual. - 9 block types: paragraph, heading, quote, code, list, table, image PLUS new divider (semantic
) and callout (with WordsEvalIntent + nestable block children). - Marks refactored from V1 template-literal `color:${string}` to structured `{type:'color'|'background', value:'#hex'}`. Type-safe. - Image upload status REMOVED from the content model (P4): the WordsImageBlockV2 no longer has `status`; it goes to runtime sidecar `provider.runtime.imageStatus: Map`. - Table V2 drops `striped` + `compact` (presentation tokens). Adds `headerRow` + `headerCol` (semantic accessibility). Per-cell and per-row `visual` allowed (background for zebra; cell padding). - Cell `tone: 'muted'|'accent'` REMOVED (was a design system token). Replace with cell.visual.background hex if user wants a tinted cell. - WordsEvalIntent declared locally in engine to keep engine framework-neutral. Parity with $uix/sema asserted at boot (TODO in R2). engine/validate-v2.ts (~520 lines): - Pure function validateWordsDocument(input) → ValidationResult. - 11 error codes: invalid-version, invalid-block-type, invalid-block-shape, invalid-children, invalid-visual-key, invalid-visual-value, invalid-mark, invalid-href, invalid-eval-intent, invalid-enum-value, invalid-number, duplicate-id, invalid-text-content, invalid-link-children. - Enforces P2: hex regex on color fields, finite numbers on dimension fields, rejects tokens / classes / var() refs / non- canonical mark shapes. - Enforces P8: per-type Pick<> at runtime via WORDS_VISUAL_KEYS_PER_TYPE whitelist. - Enforces P7: callout.intent must be one of the 6 canonical sema intents; rejects web vocabulary (`warning`/`info`/etc.). - Each error carries a JSON-pointer path (e.g. /children/1/visual/background). engine/validate-v2.test.ts (50 tests): - Top-level shape, block type registry, marks (boolean + structured + V1 reject + token reject), visual properties (allowed + rejected tokens/classes/var()/non-numeric + per-type Pick<>), id uniqueness, heading levels, list kind + indent, code text-only children, image src + width, callout SemaIntent + reject of web vocabulary + nested blocks, divider, quote.cite URL parseability, link nesting + URL parseability, table headerRow/headerCol + per-cell visual whitelist + per-row visual. Verification: 135/135 engine tests pass (85 V1 + 50 V2). V1 untouched. npm run check: 0 errors, 26 warnings (pre-existing). Next: R2 — migrator V1→V2, runtime image-status sidecar, refactor provider to consume V2 internally.

Cualquier app sabe que mide 400 (probablemente px). +- `size: 'md'` → no. Sólo tu app sabe qué es `'md'`. +- `color: '#ff5500'` → sí. Es un color CSS estándar. +- `color: 'accent'` → no. Sólo tu app sabe qué hex es `'accent'`. + +### P2 — Contenido sólo lleva valores RAW o enums semánticos + +Permitido en el documento: +- Números (`width: 400`, `cornerRadius: 16`, `padding: 8`) +- Hex colors (`color: '#ff5500'`) +- Enums semánticos (`align: 'left'|'center'|'right'`, `level: 1|2|3`, `kind: 'ordered'|'unordered'|'check'`) +- Strings literales del contenido (`src: 'https://...'`, `text: 'Hola'`) + +Prohibido en el documento: +- Tokens (`'sm'`, `'lg'`, `'accent'`, `'subtle'`) +- Clases CSS (`'rounded'`, `'shadow-lg'`) +- Referencias a recipes (`var(--words-radius-md)`) +- Nombres de componentes del framework (``, ``) +- Referencias a themes (`'dark'`, `'sepia'`) + +### P3 — El renderer traduce propiedades a estilos + +Cada target (HTML, Markdown, PDF, plain text) tiene su propio serializer. Cada uno decide qué hacer con cada propiedad: + +| Propiedad | HTML | Markdown | Plain text | +|---|---|---|---| +| `width: 400` | `style="width:400px"` | (ignorado) | (ignorado) | +| `align: 'right'` | `style="float:right"` | `` o ignorado | (ignorado) | +| `cornerRadius: 16` | `style="border-radius:16px"` | (ignorado) | (ignorado) | +| `color: '#ff5500'` | `style="color:#ff5500"` o `` legacy | (perdido) | (perdido) | + +Markdown es **lossy** — pierde lo visual, conserva la estructura. Eso es correcto. Plain text es **MUY lossy**. JSON canónico es **lossless**. + +### P4 — Runtime UI state vive FUERA del documento + +Cosas como "el upload de esta imagen está en progreso" o "este bloque está seleccionado" NO son contenido. Son estado de la sesión actual. Viven en el provider, no se serializan. + +### P5 — El engine no conoce el framework + +El motor (`engine/`) produce árboles de datos puros (`WordsRenderNode`). Eidos (Svelte) consume esos árboles. Si mañana queremos React/Vue/vanilla, sólo cambia eidos. + +### P6 — El documento es la única fuente de verdad + +La UI nunca mantiene un estado VISUAL que no pueda reconstruirse al 100% releyendo el JSON. Lo único que vive fuera del documento es el estado efímero de SESIÓN (P4): upload status, drag/drop, find/replace cursor, selección actual. + +Test operativo: cierra el editor, recarga el JSON desde cero — el render debe ser idéntico píxel a píxel (modulo el estado efímero, que se reinicia). + +Implicaciones: +- No hay "estado computado y cacheado" en la UI que sobreviva el ciclo de render. Si necesita cachearse, deriva del documento. +- No hay clases CSS "stick" añadidas por interacción del usuario que persisten — todo lo que el usuario "elige" se materializa en `block.visual.*` o en `block.{semantic-prop}`. +- Los `data-*` attributes que emite el renderer son función pura del documento. Editar el DOM directamente para "ajustar visualmente" es ANTI-PATRÓN — se pierde al re-render. + +### P7 — Vocabulario evaluativo único (sema intents) + +Cualquier propiedad del documento que carga **carga evaluativa** (positivo/negativo/neutro, severidad) usa el vocabulario canónico de sema: + +```ts +type SemaIntent = 'neutral' | 'affirm' | 'fulfill' | 'risk' | 'threat' | 'loss'; +``` + +Esto vale para `CalloutBlock.intent`, futuros `BannerBlock`, `AlertBlock`, `BadgeBlock`, etc. + +**No se permite** introducir un vocabulario paralelo en el modelo (`'warning'`, `'success'`, `'danger'`, etc.) aunque sean la convención web. Esas convenciones viven en: + +1. **UI labels** (eidos): el editor muestra "Warning" como label del intent `risk`, "Tip" para `affirm`, etc. Mapping en la capa de UI. +2. **Serializers** (engine/serializers): el Markdown export traduce `risk` → `> [!WARNING]`, el import hace el inverso. Mapping en la capa de I/O. + +La REGLA GENERAL que destila: + +> **Vocabularios canónicos del framework (sema intents, sema families, eidos variants) son los que llegan al JSON del documento.** Las convenciones externas (admonition kinds, BCP47 locales, ISO units) se aplican en la capa de serialización (import/export) — NUNCA en el modelo interno. + +### P8 — Semántica intrínseca permitida, discrecional sólo si vocabulario universal + +Reglas para decidir si una propiedad entra al modelo o se va al sidecar `visual`: + +1. **Semántica intrínseca al tipo**: ✅ entra al bloque. Sin ella el bloque no es ese bloque. + - `heading.level`, `list.kind`, `code.language`, `image.src`, `table.headerRow`, `paragraph.textAlign`, `image.align`, etc. + +2. **Semántica discrecional con vocabulario universal**: ✅ entra al bloque. El vocabulario tiene significado sin tu app. + - `callout.intent: SemaIntent` (P7 cubre). + - Marks `bold/italic/underline/strike/code` (HTML/MD universal). + - Cualquier futuro caso debe pasar el test del JSON universal. + +3. **Visual no semántico**: ✅ entra a `visual.*` como raw value. + - margin, padding, cornerRadius, borderWidth, shadow → números (px). + - background, borderColor, marks `color`/`background` → hex string. + +4. **Cualquier otra cosa**: ❌ rechazada. + - Tokens (`'sm'`, `'accent'`, `'subtle'`). + - Clases CSS (`'rounded'`, `'shadow-lg'`). + - Referencias a temas / recipes / componentes del framework. + - Vocabularios convencionales tied a un design system específico. + +--- + +## 2.

Sin tokens. +- Todo color es hex string. Sin tokens. +- `visual` es OPCIONAL. La mayoría de bloques NO la lleva. +- Cada tipo opta-IN a un subconjunto según su semántica: + +```ts +type ParagraphVisual = Pick; + +type ImageVisual = Pick; + +type CodeVisual = Pick; + +type DividerVisual = Pick; + +type CalloutVisual = Pick; +// etc. +``` + +### 3.4.bis — Labels de UI para callout (mapeo intent → convención web) + +Vive en la capa eidos (`eidos/components/words/callout/labels.ts`), NO en el modelo. Es la traducción del vocabulario canónico a las convenciones web familiares al autor: + +```ts +import type { SemaIntent } from '$uix/sema'; + +interface CalloutLabel { + readonly label: string; // texto mostrado en el chip de selección + título por defecto + readonly icon: IconName; // icono inline del callout + readonly markdownTag: string; // tag para Markdown export (GitHub admonition syntax) +} + +export const CALLOUT_LABELS: Record = { + neutral: { label: 'Note', icon: 'Info', markdownTag: 'NOTE' }, + affirm: { label: 'Tip', icon: 'Lightbulb', markdownTag: 'TIP' }, + fulfill: { label: 'Success', icon: 'Check', markdownTag: 'IMPORTANT' }, // GFM no tiene SUCCESS — IMPORTANT es el más cercano + risk: { label: 'Warning', icon: 'AlertTriangle', markdownTag: 'WARNING' }, + threat: { label: 'Danger', icon: 'Octagon', markdownTag: 'CAUTION' }, + loss: { label: 'Failure', icon: 'X', markdownTag: 'CAUTION' } // GFM no tiene FAILURE — CAUTION +}; +``` + +El usuario en la UI ve "Warning" / "Tip" / etc. — el JSON guarda `intent: 'risk'` / `'affirm'`. El Markdown export emite `> [!WARNING]` / `> [!TIP]` consumiendo el mapping en `engine/serializers/markdown.ts`. **El modelo de datos nunca menciona "warning".** + +El typing per-tipo (Pick<>) evita que un párrafo declare `shadow` (no aplica) o que una imagen declare `lineHeight` (no aplica). + +### 3.5 Inlines (texto + marks + links) + +```ts +type WordsInline = WordsTextInline | WordsLinkInline; + +interface WordsTextInline { + readonly type: 'text'; + readonly text: string; + readonly marks?: readonly WordsMark[]; +} + +interface WordsLinkInline { + readonly type: 'link'; + readonly href: string; + readonly children: readonly WordsTextInline[]; + readonly title?: string; + readonly target?: '_blank' | '_self'; + readonly rel?: string; +} + +type WordsMark = + | 'bold' | 'italic' | 'underline' | 'strike' | 'code' // semántico + | { type: 'color'; value: string } // hex raw + | { type: 'background'; value: string }; // hex raw +``` + +**Cambio vs el modelo actual:** +- Las marks parametrizadas `color:${string}` / `bgcolor:${string}` (template literal type) cambian a una shape estructurada `{ type, value }`. Más type-safe, más extensible (mañana podríamos añadir `{ type: 'fontSize'; value: 14 }` o `{ type: 'fontFamily'; value: 'monospace' }` sin tocar el parser). +- Sin marks que referencien tokens (`mark:'accent'` etc.) — sólo raw. + +--- + +## 4. Reglas de validación del modelo + +El validador del documento rechaza: + +1. **Tokens en cualquier campo string** de `visual`. Whitelist por tipo: hex regex `/^#[0-9a-f]{3,8}$/i` para colores; números puros para dimensiones. +2. **Marks no canónicas**. Sólo el conjunto declarado en `WordsMark`. +3. **Tipos de bloque no registrados** (las extensions registran sus tipos al boot). +4. **`visual` keys no permitidas para el tipo del bloque** (per-type `Pick<>` enforcement). +5. **`id` colliding** (debe ser único en el documento si está presente). +6. **`children` de tipo inválido** (un párrafo no puede contener bloques, sólo inlines). +7. **`href` de link mal formado** (parseable como URL relativa o absoluta). + +Validador como función pura: `validateWordsDocument(doc) → ValidationResult`. + +--- + +## 5. Runtime state (NO contenido) + +Estado de UI / sesión que NO va en el documento: + +```ts +class WordsProviderRuntime { + // ── Selection ── + selection: WordsSelection | null; + + // ── Image upload lifecycle (antes `image.status` en el modelo) ── + imageStatus: Map; + + // ── Drag/drop ── + dragSourceId: string | undefined; + + // ── Block selection (atomic, para image float bar) ── + selectedBlockId: string | undefined; + + // ── Edit/preview mode ── + mode: 'edit' | 'preview' | 'readonly'; + + // ── Drawer ── + drawerOpen: boolean; + drawerPanels: WordsDrawerMode[]; // derivado de selection + + // ── Find/replace ── + findQuery: string | undefined; + findMatches: readonly WordsTextMatch[]; + findActiveIndex: number; + + // ── History ── + history: WordsHistoryStack; + + // ── Composition (IME) ── + composing: boolean; +} +``` + +Este estado vive en memoria del provider.

Decisiones tomadas + open questions + +### Decisiones firmadas (review 2026-05-28) + +- **D-SEM-1**: `textAlign` / `align` se quedan como propiedades semánticas en el bloque (intent estructural — HTML histórico, accesibilidad RTL/justify). NO van a `visual.*`. P8 cubre la regla. +- **D-SEM-2**: callout vocabulary = opción C. `CalloutBlock.intent` usa `SemaIntent` canónico. Labels web viven en la capa UI; mapping admonition vive en el serializer. P7 cubre la regla. +- **D-SEM-3 → P8**: regla general firmada como principio P8 (ver sección 1). +- **Añadidos al modelo**: `DividerBlock` (hr semántico) y `CalloutBlock` (con `SemaIntent`) entran al core. +- **D-Q1**: `id` opcional, autogenerado al cargar si falta. Subir a obligatorio en v3 si emerge CRDT. +- **D-Q2**: Markdown lossy total — sin frontmatter para `visual`. JSON/HTML son los formatos lossless/cuasi-lossless. +- **D-Q3**: presets NO en core. Si se quiere, app-level (template expand → `visual.*` raw al insertar). +- **D-Q4**: engine como package separado **después** del refactor del modelo. R5 opcional. +- **D-Q5**: `width`/`height` como `number` (px asumido). Sin unit object. Si emerge `vw`/`%`, v3. +- **D-Q6**: HTML import preserva inline styles → `visual.*` raw. Mismo validador raw-only rechaza `var()` / clases / tokens. + +### Open questions (resueltas todas — sin pendientes) + +Ninguna. Arrancamos R1. + +### Q-SEM-1 — `textAlign` / `align`: semántico o visual? + +¿Se queda en el bloque como propiedad semántica (postura actual de la propuesta) o se mueve a `visual.textAlign` sidecar (postura purista)? + +- **A. Semántico (status quo)**: HTML histórico tenía `

`, accesibilidad considera el alineado como intent estructural (RTL/LTR/justify). +- **B. Visual**: HTML moderno deprecó `align=""` en favor de CSS. Markdown no lo preserva. Es puramente presentación. + +Sin decisión todavía. + +### Q-SEM-3 — Confirmar la regla general implícita + +> *"Semántica intrínseca al tipo OK. Semántica discrecional OK si es vocabulario universal (P7 ya cubre evaluativo). Todo lo demás va a `visual.*` raw."* + +¿Se firma como principio P8, o quieres una regla más estricta? + +### Q1 — ¿`id` opcional u obligatorio? + +Opciones: +- **A.** Opcional, autogenerado al cargar si falta. Bajo overhead. Documentos legacy funcionan sin tocar. +- **B.** Obligatorio. Validador rechaza documentos sin id. Más estricto, mejor para CRDT futuro. + +**Recomendación**: A. La obligatoriedad se puede subir en v3 si emerge la necesidad de CRDT. + +### Q2 — ¿Markdown frontmatter para `visual`? + +Opciones: +- **A.** Markdown lossy total — no incluye `visual`. Más limpio. +- **B.** Frontmatter YAML con `visual` por block id — preserva, pero `.md` ya no es MD puro. + +**Recomendación**: A. MD para portabilidad. JSON/HTML para fidelidad. + +### Q3 — ¿"Block presets" como feature? + +Estilos pre-guardados ("Card warning", "Card info") que el usuario puede aplicar: +- **A.** No en core. Si se quiere, app-level: el editor expone "templates" que expanden a `visual.*` raw al insertar. +- **B.** En core. Presets viven en el design system, el bloque guarda `preset: 'warning'` y el renderer expande. + +**Recomendación**: A. B contamina contenido con design system (rompe P1). + +### Q4 — ¿Engine como paquete separado en este sprint? + +- **A.** Sí, durante el refactor. `src/uix/words-engine/` independiente, eidos consume. +- **B.** Después. Refactor del modelo primero, package boundary luego. + +**Recomendación**: B. Más fácil iterar el modelo dentro del repo primero, package en segundo sprint. + +### Q5 — ¿Width/height de imagen son `number | { value: number; unit: 'px' | '%' | 'vw' }`? + +Width como número simple asume px. Pero `100%` width es un caso real ("imagen ocupa todo el ancho"). +- **A.** Number = px siempre. `100%` se expresa como `width: undefined` (= auto) + `visual.height: number`. +- **B.** Union con unit. `width: { value: 100, unit: '%' }`. + +**Recomendación**: A para simplicidad. Si emerge la necesidad de `vw`, se sube a B en v3. + +### Q6 — ¿Validar inline styles del HTML import? + +Cuando el usuario pega HTML con `

`, ¿el parser: +- **A.** Reescribe a `visual.marginBlockStart: 20, ..., text.color: '#ff0000'`? +- **B.** Descarta los estilos? Sólo importa estructura semántica. + +**Recomendación**: A. Preservar la intención del usuario. Aplicar el mismo validador raw-only (rechazar `var()`, clases, etc.). + +--- + +## 11. No-objetivos (a propósito) + +- **Compatibilidad nativa con Tiptap/ProseMirror schemas**. Si emerge, se hace adapter. Por ahora la shape es propia. +- **CRDT/colaboración en tiempo real**. Los `id` opcionales preparan el terreno, pero el sprint actual no lo incluye. +- **Comments / change tracking**. Otro sidecar runtime futuro. +- **Math / formula blocks** (LaTeX).
