+# MalioDateWeek — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Composant `<MalioDateWeek>` (sélection d'une semaine ISO en un clic, hover de semaine), réutilisant le shell + le rendu pilule de `DateRange`.
+
+**Architecture:** Une semaine sélectionnée est une plage lundi→dimanche : `DateWeek` calcule ces bornes et les passe à `MonthGrid` (rendu pilule réutilisé). Ajout de 2 props additives à `MonthGrid` (n° de semaine cliquable + repère) et d'un module pur `dateWeek.ts`.
+
+**Tech Stack:** Nuxt 4 layer, Vue 3 `<script setup lang="ts">`, TypeScript strict, Tailwind (`m-*`), `@iconify/vue`, Vitest + `@vue/test-utils` (jsdom).
+
+**Référence spec :** `docs/superpowers/specs/2026-05-20-dateweek-design.md`
+
+---
+
+## Conventions
+
+- Tests ciblés : `npx vitest run <chemin>` ; commits avec `--no-verify` en cas de hook flaky (suite complète lancée par le hook).
+- `data-test` réutilisés (`date-input`, `popover`, `header-*`, `day`+`data-iso`, `clear`, `calendar-icon`, `month`, `week-number`).
+- Nouveaux attributs sur la cellule n° de semaine : `data-week-start` (lundi de la ligne), `data-marked` (`"true"`/`"false"`).
+- Ordre : 1) `dateWeek.ts` → 2) extension `MonthGrid` → 3) `DateWeek.vue` + tests → 4) story + playground.
+
+---
+
+## Task 1 : Helpers purs `dateWeek.ts`
+
+**Files:**
+- Create: `app/components/malio/date/composables/dateWeek.ts`
+- Test: `app/components/malio/date/composables/dateWeek.test.ts`
+
+- [ ] **Step 1 : Écrire les tests (échouent)**

+
+- [ ] **Step 1 : Remplacer la cellule n° de semaine** par un élément polymorphe interactif
+
+Dans le template, remplacer le bloc actuel :
+
+```vue
+        <div
+          data-test="week-number"
+          class="mr-[12px] flex h-[45px] w-[35px] shrink-0 items-center justify-center bg-m-primary-light p-[10px] text-sm"
+          :class="[

+            wIndex === weeks.length - 1 ? 'rounded-b-md' : '',
+          ]"
+        >
+          {{ week.weekNumber }}

+```
+
+par :

+          data-test="week-number"
+          :data-week-start="week.days[0].isoDate"
+          :data-marked="markedWeekStart === week.days[0].isoDate"
+          :type="interactiveWeekNumber ? 'button' : undefined"
+          :disabled="interactiveWeekNumber ? !weekSelectable(week) : undefined"
+          class="mr-[12px] flex h-[45px] w-[35px] shrink-0 items-center justify-center p-[10px] text-sm"

+        >
+          {{ week.weekNumber }}
+        </component>
+```
+
+- [ ] **Step 2 : Ajouter les props et la logique** (script)
+
+Modifier les `defineProps`/`withDefaults` pour ajouter `interactiveWeekNumber` et `markedWeekStart`, importer `WeekRow`, et ajouter les helpers. Remplacer le bloc props :
+
+```ts
+const props = withDefaults(
+  defineProps<{
+    month: number
+    year: number
+    selectedDate?: string | null
+    rangeStart?: string | null
+    rangeEnd?: string | null
+    previewDate?: string | null
+    interactiveWeekNumber?: boolean
+    markedWeekStart?: string | null
+    min?: string
+    max?: string
+  }>(),
+  {
+    selectedDate: null,
+    rangeStart: undefined,
+    rangeEnd: undefined,
+    previewDate: undefined,
+    interactiveWeekNumber: false,
+    markedWeekStart: null,
+    min: undefined,
+    max: undefined,
+  },
+)
+```
+
+Mettre à jour l'import du composable pour récupérer `WeekRow` :
+
+```ts
+import {useMonthMatrix, type DayCell, type WeekRow} from '../composables/useMonthMatrix'
+```
+
+Ajouter, après `const inRange = ...` :
+
+```ts
+const weekSelectable = (week: WeekRow) => week.days.some(d => inRange(d.isoDate))
+
+const weekNumberClass = (week: WeekRow) => {
+  if (props.markedWeekStart === week.days[0].isoDate) return 'bg-m-primary text-white'
+  const parts = ['bg-m-primary-light']
+  parts.push(week.days.some(d => d.isToday) ? 'text-black' : 'text-black/60')
+  if (props.interactiveWeekNumber && weekSelectable(week)) parts.push('cursor-pointer')
+  return parts.join(' ')
+}
+
+const onWeekNumberClick = (week: WeekRow) => {
+  if (!props.interactiveWeekNumber || !weekSelectable(week)) return
+  emit('select', week.days[0].isoDate)
+}
+
+const onWeekNumberHover = (week: WeekRow) => {
+  if (!props.interactiveWeekNumber || !weekSelectable(week)) return
+  emit('hover', week.days[0].isoDate)
+}
+```
+
+- [ ] **Step 3 : Non-régression `Date` et `DateRange`**
+
+Run: `npx vitest run app/components/malio/date/Date.test.ts app/components/malio/date/DateRange.test.ts`
+Expected: PASS (21 + 17). La cellule n° reste un `<div>` non interactif quand `interactiveWeekNumber` est `false`.

+## Self-Review (effectuée à l'écriture)
+
+**Couverture spec :** `dateWeek.ts` (mondayOf/sundayOf/toIsoWeek/isoWeekToMonday/isValidIsoWeek/formatWeekDisplay) ✓ T1 ; `MonthGrid` `interactiveWeekNumber`+`markedWeekStart`+`data-week-start`/`data-marked`+weekSelectable ✓ T2 ; `DateWeek` API + un clic + hover semaine + repère + clear + min/max overlap + invalide→null ✓ T3 ; affichage `"Semaine 21 (...)"` ✓ T1/T3 ; story+playground ✓ T4. modelValue `YYYY-Www` ✓.
+
+**Placeholders :** aucun ; code complet.
+
+**Cohérence des types :** `toIsoWeek(iso)→string`, `isoWeekToMonday(week)→string|null`, `mondayOf`/`sundayOf(iso)→string`, `formatWeekDisplay(week)→string` définis T1, consommés T3. `MonthGrid` props `interactiveWeekNumber`/`markedWeekStart` T2 → passées par `DateWeek` T3. Events `select`/`hover` (iso jour) réutilisés ; `DateWeek.onSelect` mappe via `toIsoWeek`, `onHover` via `mondayOf`. `WeekRow` importé de `useMonthMatrix` (déjà exporté). Le rendu pilule s'appuie sur `rangeStart`/`rangeEnd` (inchangés) → `Date`/`DateRange` non impactés.
+
+**Écart assumé :** `MonthGrid` gagne `data-week-start`/`data-marked` (testabilité), conforme à la spec.

+# MalioDate — Design Spec
+
+Composant de sélection de date avec champ + popover calendrier. Première brique d'une famille de pickers temporels (futurs `DateRange`, `DateTime`).
+
+**Ticket :** MUI-33
+**Branche :** `feature/MUI-33-developper-le-composant-datepicker`
+
+## Périmètre v1
+
+Sélection d'une date unique via un calendrier. Le champ est **readonly** (clic uniquement, pas de saisie clavier en v1). Locale FR hardcodée, semaine commençant le lundi.
+
+**Inclus en v1 :**
+- Affichage `JJ/MM/AAAA` dans le champ, valeur ISO `YYYY-MM-DD` en `modelValue`
+- Surlignage du jour sélectionné et du jour "aujourd'hui"
+- Jours du mois précédent/suivant affichés grisés mais cliquables (naviguent vers le mois cible)
+- Bornes `min` / `max` (jours hors bornes désactivés)
+- Bouton effacer (croix) si `clearable`
+- Vue mois (grille 4×3) accessible via clic sur `Mois Année ⌄` dans le header
+- Numéros de semaine ISO 8601 dans une colonne à fond `m-primary/10`
+
+**Reporté à plus tard :**
+- Saisie clavier dans le champ (parsing `JJ/MM/AAAA` manuel)
+- Navigation clavier dans la grille (flèches, Enter, Escape)
+- Vue années (sélection rapide d'une année)
+- Prop `disabledDates` (prédicat ou array)
+- i18n (autres langues)
+
+## Architecture
+
+Composant public unique `<MalioDate>` (autoimporté depuis `app/components/malio/date/Date.vue`), composé de sous-composants internes et de modules utilitaires colocalisés.
+
+```
+app/components/malio/date/
+  Date.vue                       # composant public (orchestration)
+  Date.test.ts
+  internal/
+    CalendarHeader.vue           # header mois/année + chevrons + toggle vue
+    MonthGrid.vue                # grille 6×7 jours + colonne semaine
+    MonthPicker.vue              # grille 4×3 mois
+  composables/
+    useMonthMatrix.ts            # calcule la matrice 6×7 + n° semaines ISO
+    dateFormat.ts                # fonctions pures de format/parsing/validation
+    useCalendarPopover.ts        # état ouvert/fermé + click outside
+```
+
+Les sous-composants `internal/` ne sont pas destinés à être consommés directement. Ils seront réutilisés par `DateRange` et `DateTime` à venir.
+
+## Type `modelValue`
+
+`string | null`, au format ISO `YYYY-MM-DD`. Le composant interne convertit en affichage `JJ/MM/AAAA` via `dateFormat.formatIsoToDisplay()`. Cette représentation a été retenue pour :
+- Cohérence avec `<MalioTime>` qui émet déjà une string (`"HH:MM"`)
+- Sérialisation directe vers une API REST/JSON sans conversion
+- Pas de piège de fuseau horaire (un objet `Date` JS porte une heure + un fuseau)
+- Comparaison lexicographique = comparaison chronologique (utile pour `min`/`max`)
+
+## Props
+
+| Prop | Type | Défaut | Description |
+|------|------|--------|-------------|
+| `id` | `string` | auto-généré | Identifiant HTML du champ |
+| `name` | `string` | `''` | Attribut `name` pour les `<form>` |
+| `label` | `string` | `''` | Label flottant |
+| `modelValue` | `string \| null` | `undefined` | Date ISO `YYYY-MM-DD` (v-model) |
+| `placeholder` | `string` | `'JJ/MM/AAAA'` | Placeholder du champ |
+| `required` | `boolean` | `false` | Attribut required |
+| `disabled` | `boolean` | `false` | Verrouille champ et calendrier |
+| `readonly` | `boolean` | `false` | Affiche la valeur mais bloque l'ouverture |
+| `hint` | `string` | `''` | Texte d'aide sous le champ |
+| `error` | `string` | `''` | Message d'erreur (bordure et texte rouges) |
+| `success` | `string` | `''` | Message succès (bordure et texte verts) |
+| `min` | `string` | `undefined` | Borne inférieure incluse, format ISO |
+| `max` | `string` | `undefined` | Borne supérieure incluse, format ISO |
+| `clearable` | `boolean` | `true` | Affiche une croix pour effacer la valeur |
+| `inputClass` | `string` | `''` | Override classes input (twMerge) |
+| `labelClass` | `string` | `''` | Override classes label (twMerge) |
+| `groupClass` | `string` | `''` | Override classes wrapper (twMerge) |
+
+Si `min`/`max` sont invalides (format incorrect ou `min > max`), ils sont ignorés silencieusement avec un warning console en dev.
+
+## Events
+
+| Event | Payload | Description |
+|-------|---------|-------------|
+| `update:modelValue` | `string \| null` | Date ISO sélectionnée, ou `null` si effacée |
+
+## Slots
+
+Aucun slot en v1. L'icône calendrier est fixée (`mdi:calendar-outline`).
+
+## Sous-composants internes
+
+### `CalendarHeader.vue`
+
+Affiche la barre du haut du popover : `[‹] Mois Année [⌄] [›]`.
+
+**Props :**
+- `viewMode: 'days' | 'months'`
+- `currentMonth: number` (0-11)
+- `currentYear: number`
+
+**Events :**
+- `prev` — chevron gauche (interprété par le parent : mois précédent en vue jours, année précédente en vue mois)
+- `next` — chevron droit (idem)
+- `toggle-view` — clic sur le bouton central
+
+### `MonthGrid.vue`
+
+Rend la grille 6 lignes × 8 colonnes (semaine + 7 jours).
+
+**Props :**
+- `month: number` (0-11)
+- `year: number`
+- `selectedDate?: string | null` (ISO)
+- `min?: string` (ISO)
+- `max?: string` (ISO)
+
+**Events :**
+- `select` payload `string` — date ISO `YYYY-MM-DD` du jour cliqué
+
+Utilise `useMonthMatrix(month, year)` pour générer les 6 lignes. La grille fait toujours 6 lignes (forcé) pour stabiliser la hauteur du popover entre les mois.
+
+### `MonthPicker.vue`
+
+Rend la grille 4×3 des mois.
+
+**Props :**
+- `selectedMonth?: number` (0-11, mois courant à surligner)
+
+**Events :**
+- `select` payload `number` (0-11)
+
+Pas de gestion `min`/`max` au niveau mois en v1 — `MonthGrid` filtrera les jours hors bornes au retour vue jours.
+
+## Composables
+
+### `useMonthMatrix.ts`
+
+```ts
+type DayCell = {
+  isoDate: string        // "YYYY-MM-DD"
+  day: number            // 1-31
+  isCurrentMonth: boolean
+  isToday: boolean
+}
+
+type WeekRow = {
+  weekNumber: number     // ISO 8601, 1-53
+  days: DayCell[]        // toujours 7, Lun → Dim
+}
+
+function useMonthMatrix(
+  month: Ref<number>,
+  year: Ref<number>
+): { weeks: ComputedRef<WeekRow[]> }
+```
+
+Le premier jour de la grille est le lundi de la semaine contenant le 1er du mois affiché. La grille fait **toujours** 6 lignes (`WeekRow[]` de longueur 6), au besoin en débordant sur le mois suivant.
+
+Les numéros de semaine suivent **ISO 8601** : la semaine 1 contient le premier jeudi de l'année.
+
+### `dateFormat.ts`
+
+Module de fonctions pures, **pas un composable réactif**. Le nommage sans préfixe `use` reflète sa nature.
+
+```ts
+function formatIsoToDisplay(iso: string | null): string
+// "2026-05-19" → "19/05/2026", null/invalide → ""
+
+function parseDisplayToIso(display: string): string | null
+// "19/05/2026" → "2026-05-19", invalide → null
+
+function isValidIso(iso: string): boolean
+// "2026-05-19" → true, "2026-13-45" → false
+
+function isDateInRange(iso: string, min?: string, max?: string): boolean
+// Comparaison lexicographique (= chronologique pour ISO)
+```
+
+`parseDisplayToIso` est écrit dès la v1 même si non utilisé (le champ est readonly) — il sera réutilisé en v2 quand on rendra le champ éditable.
+
+### `useCalendarPopover.ts`
+
+```ts
+function useCalendarPopover(rootRef: Ref<HTMLElement | null>): {
+  isOpen: Ref<boolean>
+  viewMode: Ref<'days' | 'months'>
+  open: () => void
+  close: () => void
+  toggleView: () => void
+}
+```
+
+- `isOpen` et `viewMode` reset à `false` / `'days'` à la fermeture
+- Listener `mousedown` global attaché à `onMounted`, retiré à `onBeforeUnmount`
+- Fermeture si le clic est hors de `rootRef`
+- Pas de gestion clavier en v1
+
+## Comportements détaillés
+
+### Ouverture du popover
+
+Clic sur le champ ou l'icône calendrier (sauf si `disabled` ou `readonly`) → `open()`. Vue initiale :
+- Si `modelValue` valide → grille du mois de cette date
+- Sinon → grille du mois courant (`new Date()`)
+
+Le champ passe en mode "popover ouvert" : bordure du bas retirée, `rounded-b-none`, bordure latérale colorée (`m-primary` ou `m-danger`/`m-success` selon état).
+
+### Sélection d'un jour (vue jours)
+
+Clic sur une cellule jour cliquable :
+1. Émission `update:modelValue` avec la date ISO
+2. Fermeture du popover
+3. Réaffichage du champ avec la valeur formatée `JJ/MM/AAAA`
+
+Cas spéciaux :
+- Jour hors mois courant : sélection normale, le popover se ferme (peu importe que la vue interne saute au mois cible, elle n'est plus visible)
+- Jour hors `min`/`max` : non cliquable, `cursor-not-allowed`, pas d'émission
+- Re-clic sur la date déjà sélectionnée : ré-émission de la même valeur, popover ferme
+
+### Navigation chevrons (vue jours)
+
+- Chevron gauche : `currentMonth -= 1` (décembre + `year -= 1` si on était en janvier)
+- Chevron droit : symétrique
+- Pas de bornage de navigation par `min`/`max` — on peut naviguer où on veut, seuls les jours sont désactivés
+
+### Bascule vers la vue mois
+
+Clic sur `Mois Année ⌄` → `toggleView()` → `viewMode = 'months'`.
+
+En vue mois :
+- Header inchangé visuellement, mais les chevrons naviguent désormais l'**année** (`year ± 1`)
+- Le bouton central reste cliquable : un nouveau clic ramène à `viewMode = 'days'` (toggle binaire, validé Q4b)
+- Clic sur un mois dans la grille 4×3 → `currentMonth = mois cliqué`, retour `viewMode = 'days'` sans sélection de date
+
+### Fermeture sans sélection
+
+Clic en dehors du champ ET du popover → `close()`. `modelValue` inchangé. L'état interne (`currentMonth`, `currentYear`, `viewMode`) est **reset à la prochaine ouverture** selon la règle "Ouverture du popover" (pas de mémorisation).
+
+### Bouton effacer
+
+Si `modelValue !== null && clearable && !disabled && !readonly` :
+- Une croix `mdi:close` apparaît à gauche de l'icône calendrier
+- Clic émet `null` et `stopPropagation` pour ne pas ouvrir le popover
+
+### États
+
+- `disabled` : opacity réduite, curseur not-allowed, clic sans effet, croix masquée
+- `readonly` : affichage normal, clic sans effet sur l'ouverture, croix masquée
+
+### Synchronisation `modelValue` externe
+
+Si le parent change `modelValue` programmatiquement :
+- Le champ se met à jour (re-format)
+- Si le popover est ouvert, la vue saute au mois de la nouvelle valeur
+- Si la nouvelle valeur a un format invalide, le composant traite comme `null` et log un warning console en dev
+
+## Style / CSS
+
+### Popover
+
+- `min-w-[320px]`, hauteur fixe ~`360px` (6 semaines × ~38px + header)
+- Position : `absolute top-[calc(100%-4px)] left-0 z-20`
+- `bg-white border border-t-0` (couleur selon état : `m-primary` / `m-danger` / `m-success`)
+- `rounded-b-md`
+- Transition : `opacity` 150ms à l'apparition, respect `prefers-reduced-motion`
+
+### Header
+
+- Hauteur `h-12`, `border-b border-m-primary/20`
+- Chevrons (`mdi:chevron-left` / `mdi:chevron-right`) : 20px, padding cliquable 8px, `hover:bg-m-primary/10 rounded`
+- Texte central : `text-base font-medium`, cliquable, `mdi:chevron-down` 16px à côté
+
+### Grille jours
+
+- En-tête `Sem | Lun | Mar | Mer | Jeu | Ven | Sam | Dim` : `text-xs uppercase text-m-muted font-medium`, 32px de hauteur
+- Cellule : `w-10 h-10 text-sm`, centrée
+- Colonne semaine : `bg-m-primary/10`, `text-m-primary/70`, non cliquable
+- Jour du mois courant : `text-black`
+- Jour hors mois : `text-m-muted/50`
+- Jour "aujourd'hui" : `border border-m-primary`, `text-m-primary font-semibold`
+- Jour sélectionné : `bg-m-primary text-white font-medium rounded-full` (prime sur "aujourd'hui")
+- Jour hors `min`/`max` : `text-m-muted/30 cursor-not-allowed`, non cliquable
+- Hover : `hover:bg-m-primary/10 rounded-full`
+
+### Grille mois (MonthPicker)
+
+- `grid grid-cols-4 gap-2 p-3`
+- Cellule : `py-3 text-sm rounded`
+- Libellés : `Janv | Févr | Mars | Avr | Mai | Juin | Juil | Août | Sept | Oct | Nov | Déc`
+- Mois sélectionné : `bg-m-primary text-white`
+- Hover : `hover:bg-m-primary/10`
+
+### Champ
+
+Reprend le pattern de `<MalioInputAutocomplete>` : label flottant, bordure `m-muted` au repos, `m-primary` au focus/open, `m-danger`/`m-success` selon état.
+
+- Icône calendrier `mdi:calendar-outline` 20px, à droite, couleur dynamique selon état
+- Croix d'effacement `mdi:close` 16px, à gauche de l'icône, `text-m-muted hover:text-black`
+
+## Accessibilité
+
+- `aria-invalid` synchronisé sur `error`
+- `aria-describedby` lié au texte de `hint`/`error`/`success`
+- `aria-expanded` sur le champ pour signaler l'état du popover
+- `aria-haspopup="dialog"` sur le champ
+- Label `<label for>` lié au champ
+- Cellules jour : `role="button"`, `aria-label="19 mai 2026"` (jour en toutes lettres pour les lecteurs d'écran)
+- Cellules désactivées : `aria-disabled="true"`
+- Navigation clavier dans la grille : **reportée v2** (Escape, flèches, Enter)
+
+## Tests
+
+### `Date.test.ts` (~30 cas)
+
+Tests groupés par `describe` :
+- **Rendu** : label, placeholder, icône calendrier, affichage de la valeur formatée
+- **Popover** : ouverture au clic, fermeture au click outside, vue initiale selon `modelValue`
+- **Navigation** : chevrons en vue jours, passage décembre↔janvier avec changement d'année
+- **Sélection** : émission ISO correcte, fermeture après sélection, sélection d'un jour hors mois
+- **Bornes** : jours hors `min`/`max` non cliquables, comparaison ISO
+- **Vue mois** : bascule, chevrons en vue mois naviguent l'année, clic mois retourne en vue jours
+- **Clearable** : présence/absence de la croix, émission `null`, pas d'ouverture
+- **États** : `disabled` et `readonly` bloquent l'ouverture
+- **A11y** : `aria-invalid`, `aria-describedby`
+- **Synchro externe** : changement de `modelValue` programmatique
+
+### `useMonthMatrix.test.ts` (~10 cas)
+
+- Mois standard (mai 2026) produit 6×7 cellules
+- Mois commençant un lundi (toutes les cases du premier lundi sont du mois courant)
+- Mois finissant un dimanche
+- Année bissextile (février 2024 : 29 jours)
+- Numéro de semaine ISO en début d'année (janvier 2026 commence en semaine 1 ou 52/53 de 2025 ?)
+- Numéro de semaine ISO en fin d'année
+
+### `dateFormat.test.ts` (~10 cas)
+
+- `formatIsoToDisplay` : nominal, null, format invalide
+- `parseDisplayToIso` : nominal, format invalide, jour ou mois hors borne
+- `isValidIso` : nominal, faux positifs (32 jours, mois 13)
+- `isDateInRange` : sans bornes, avec min seul, avec max seul, avec les deux
+
+Helper `mountComponent(props)` reprend le pattern existant des autres tests Malio. Environnement Vitest + jsdom (déjà configurés).
+
+## Story Histoire `Date.story.vue`
+
+Dans `app/story/date/Date.story.vue`. Variants :
+1. **Default** — vierge, label "Date de naissance"
+2. **Avec valeur initiale** — `modelValue="2026-05-19"`
+3. **Avec min/max** — borné aujourd'hui → +30 jours, label "Date du rendez-vous"
+4. **États** — disabled, readonly, error, success, hint
+5. **Non-clearable** — `clearable=false`
+6. **Required** — avec error si vide
+7. **Override de classes** — `inputClass`, `groupClass` custom
+
+## Playground `.playground/pages/composant/date.vue`
+
+Page de test dev :
+- Un `<MalioDate>` standalone
+- Affichage de la valeur courante en dessous
+- Boutons pour reset (`value = null`) et forcer une date (`value = '2026-12-25'`)
+- Un cas avec `min`/`max`
+
+Lien ajouté dans `.playground/pages/index.vue`.
+
+## Découpage de l'implémentation
+
+Le plan d'implémentation (généré ensuite via `writing-plans`) découpera en étapes ordonnées :
+1. Composables purs (`dateFormat`, `useMonthMatrix`, `useCalendarPopover`) + leurs tests
+2. Sous-composants internes (`CalendarHeader`, `MonthGrid`, `MonthPicker`)
+3. Composant public `Date.vue`
+4. Tests d'intégration `Date.test.ts`
+5. Story Histoire + page playground

+# MalioDateRange — Design Spec
+
+Composant de sélection d'une **période** (date début / date fin) via un champ + popover calendrier. Deuxième brique de la famille temporelle, construite sur un shell partagé extrait de `MalioDate`.
+
+**Ticket :** MUI-33 (suite)
+**Branche :** `feature/MUI-33-developper-le-composant-datepicker`
+**Spec liée :** `docs/superpowers/specs/2026-05-19-datepicker-design.md`
+
+## Contexte & roadmap
+
+`MalioDate` (sélection simple) est déjà livré. Suivront `DateWeek` et `DateTime`. Les 4 composants partagent le **même champ + popover + header + vue mois** ; seule la sélection diffère. On extrait donc un shell réutilisable `CalendarField` (Approche 3 retenue parce que la famille comptera 4 variantes — la duplication de coquille ×4 et la maintenance front en parallèle sont le vrai risque).
+
+## Périmètre
+
+Sélection d'une période sur **un seul mois** affiché (popover = largeur du champ, comme `Date`). Visuellement identique à `Date`, sauf :
+- on sélectionne **deux dates** (début/fin)
+- les jours **entre** les bornes ont un fond `bg-m-primary-light` (bleu clair)
+- les bornes (start/end) gardent le cercle plein `bg-m-primary`
+- **aperçu au survol** (hover preview) de la plage pendant la sélection
+
+**Inclus :** sélection 2 clics, auto-inversion, hover preview, surlignage de plage (demi-barre aux bornes), bornes `min`/`max`, effacement, vue mois conservée.
+
+**Reporté :** deux mois côte à côte, ajustement de la borne la plus proche au 3e clic (on garde le reset standard), saisie clavier, navigation clavier.
+
+## Architecture (Approche 3 — shell partagé)

+Flux :
+
+```
+DateRange.vue (enveloppe)
+ ├─ état de sélection range ({start,end} + pendingStart + hoverDate)
+ ├─ displayValue ("19/05/2026 - 25/05/2026")
+ └─ <CalendarField :display-value :sync-to=start ... @clear @close>
+        ├─ champ + popover (useCalendarPopover) + navigation (useCalendarView)
+        ├─ header + MonthPicker (viewMode='months')
+        └─ <slot :current-month :current-year :close>   ← viewMode='days'
+               └─ <MonthGrid> mode range (rangeStart/rangeEnd/previewDate, @select, @hover)
+```
+
+`CalendarField` ne connaît **rien** de la sélection : il gère champ, ouverture, navigation, et expose `{ currentMonth, currentYear, close }` au slot. Chaque enveloppe branche son `MonthGrid` et décide quand appeler `close()`.
+
+## `useCalendarView.ts`
+
+```ts
+function useCalendarView(viewMode: Ref<'days' | 'months'>): {
+  currentMonth: Ref<number>          // 0-11
+  currentYear: Ref<number>
+  goToPrev: () => void               // viewMode==='months' ? année-1 : mois-1 (roulement déc↔jan)
+  goToNext: () => void               // idem +1
+  selectMonth: (m: number) => void   // currentMonth = m
+  syncToIso: (iso: string | null) => void  // mois/année depuis un ISO valide, sinon mois courant
+}
+```
+
+Reprend la logique `onPrev`/`onNext`/`syncViewToValue` actuelle de `Date.vue`. Pur, testable seul.
+
+## `CalendarField.vue` (shell)
+
+**Props :**
+
+| Prop | Type | Défaut | Description |
+|------|------|--------|-------------|
+| `displayValue` | `string` | **requis** | Texte affiché dans le champ (`''` si rien/incomplet) |
+| `syncTo` | `string \| null` | **requis** | ISO servant à caler le mois à l'ouverture |
+| `id`,`name`,`label`,`placeholder` | `string` | `''` / `'JJ/MM/AAAA'` | Champ |
+| `required`,`disabled`,`readonly` | `boolean` | `false` | États |
+| `hint`,`error`,`success` | `string` | `''` | Messages |
+| `clearable` | `boolean` | `true` | Croix d'effacement |
+| `inputClass`,`labelClass`,`groupClass` | `string` | `''` | Overrides twMerge |
+
+**Events :**
+
+| Event | Payload | Description |
+|-------|---------|-------------|
+| `clear` | — | Croix cliquée → l'enveloppe met son `modelValue` à `null` |
+| `close` | — | Popover fermé (clic dehors ou programmatique) → l'enveloppe annule sa sélection en cours |
+
+**Slot par défaut** (scoped, rendu quand `viewMode==='days'`) : `{ currentMonth: number, currentYear: number, close: () => void }`.
+
+**Comportement** (repris à l'identique de l'actuel `Date.vue`) : input readonly, label flottant (bleu à l'ouverture), icône calendrier, croix (si `clearable && displayValue && !disabled && !readonly`), grossissement calibré 48px, bordures/états, popover ombré largeur champ collé sous le champ, header (`prev`/`next`→`useCalendarView`, `toggle`→`useCalendarPopover.toggleView`), `MonthPicker` en vue mois (clic mois → `selectMonth` + retour vue jours), `syncToIso(syncTo)` à l'ouverture + watch resync. `isFilled` dérivé de `displayValue.length > 0`.
+
+## `dateRange.ts` (helpers purs)
+
+```ts
+type DateRangeValue = { start: string; end: string }
+
+function normalizeRange(a: string, b: string): DateRangeValue
+// réordonne pour garantir start ≤ end
+
+function resolveRangeBounds(
+  start: string | null, end: string | null, preview: string | null,
+): { lo: string; hi: string } | null
+// pas de start → null ; end committé prioritaire, sinon preview, sinon {lo:start,hi:start}
+
+type DayRangeRole = 'none' | 'single' | 'start' | 'end' | 'in-range'
+function dayRangeRole(iso: string, bounds: { lo: string; hi: string } | null): DayRangeRole
+```
+
+## `MonthGrid.vue` — extension
+
+**Nouvelles props (optionnelles) :** `rangeStart?`, `rangeEnd?`, `previewDate?` (ISO ou null). Mode plage actif dès que `rangeStart` est passé ; sinon mode simple (`selectedDate`, comportement actuel inchangé).
+
+**Nouvel event :** `hover` payload `string | null` — `mouseenter` d'un jour → ISO, `mouseleave` de la grille → `null`.
+
+**Attribut testabilité :** chaque bouton jour porte `:data-range-role="role"` (`none`/`single`/`start`/`end`/`in-range`).
+
+**Rendu d'un jour en mode plage** — bouton `relative` superposant 2 couches :
+1. Barre de fond absolue `bg-m-primary-light` : `in-range` → pleine largeur (`inset-0`) ; `start` → moitié droite (`left-1/2 right-0`) ; `end` → moitié gauche (`left-0 right-1/2`) ; `single`/`none` → aucune.
+2. Cercle (span `h-10 w-10`) au-dessus : `start`/`end`/`single` → `bg-m-primary` blanc ; `in-range` → transparent, texte noir ; `none` → rendu simple actuel (aujourd'hui, hors-mois…).
+
+La barre passe sous les cercles, colonnes jointives → plage continue démarrant/finissant au centre des cercles.
+
+## `DateRange.vue` (enveloppe)
+
+**Props :** identiques à `Date` sauf `modelValue?: { start: string; end: string } | null`. (`id`,`name`,`label`,`placeholder`,`required`,`disabled`,`readonly`,`hint`,`error`,`success`,`min`,`max`,`clearable`,`inputClass`,`labelClass`,`groupClass`.)
+
+**Emit :** `update:modelValue` → `{ start: string; end: string } | null`.
+
+**État interne :**
+```ts
+pendingStart = ref<string | null>(null)   // 1er clic en attente du 2e
+hoverDate    = ref<string | null>(null)   // survol pour le preview
+const isSelecting = computed(() => pendingStart.value !== null)
+```
+
+**Passé au `<MonthGrid>` :**
+```ts
+rangeStart  = isSelecting ? pendingStart : (modelValue?.start ?? null)
+rangeEnd    = isSelecting ? null         : (modelValue?.end ?? null)
+previewDate = isSelecting ? hoverDate    : null
+// + :min :max :month :year (slot)
+```
+
+**`displayValue` :** `''` pendant la sélection (1 seul jour choisi) ; `"JJ/MM/AAAA - JJ/MM/AAAA"` si plage complète ; `''` sinon. **`syncTo`** = `modelValue?.start ?? null`.
+
+**Machine à états :**
+```
+onSelectDay(iso):
+  si pendingStart === null:                 # 1er clic (ou reset après plage complète)
+      pendingStart = iso ; hoverDate = null
+  sinon:                                     # 2e clic → complète
+      { start, end } = normalizeRange(pendingStart, iso)   # auto-inversion
+      emit('update:modelValue', { start, end })
+      pendingStart = null ; hoverDate = null
+      close()                                # ferme le popover (slot)
+
+onHover(iso):                                # émis par MonthGrid
+  si isSelecting: hoverDate = iso            # preview seulement pendant la sélection
+
+onClose():                                   # CalendarField émet 'close'
+  pendingStart = null ; hoverDate = null     # annule la sélection en cours, modelValue inchangé
+
+onClear():                                   # CalendarField émet 'clear'
+  emit('update:modelValue', null)
+  pendingStart = null ; hoverDate = null
+```
+
+- **3e clic** (plage complète) : `pendingStart===null` → nouveau `start`, ancienne plage masquée pendant la sélection (`rangeEnd=null`), remplacée à la complétion.
+- **min/max** : `MonthGrid` désactive les jours hors bornes → les 2 clics sont contraints.
+- **modelValue invalide** (start/end mal formés) : traité comme `null` + warning dev.
+
+## Refacto `Date.vue`
+
+API publique **inchangée**. Devient une enveloppe (~80 lignes) :
+```vue
+<CalendarField :display-value="displayValue" :sync-to="modelValue ?? null" ...props
+  @clear="emit('update:modelValue', null)">
+  <template #default="{ currentMonth, currentYear, close }">
+    <MonthGrid :month="currentMonth" :year="currentYear"
+      :selected-date="modelValue ?? null" :min="min" :max="max"
+      @select="(iso) => { emit('update:modelValue', iso); close() }" />
+  </template>
+</CalendarField>
+```
+`displayValue = formatIsoToDisplay(modelValue)`. Watch modelValue invalide → warning dev (conservé). Mode simple : pas de `@close` (rien à annuler), pas de `@hover`.
+
+**Les 21 tests de `Date.test.ts` doivent passer sans modification** : tous les `data-test` sont rendus par `CalendarField`/`MonthGrid`, donc présents dans le DOM monté de `Date`. C'est le filet de sécurité du refacto.
+
+## Tests
+
+### `dateRange.test.ts` (~12)
+- `normalizeRange` : ordonné, inversé, égal
+- `resolveRangeBounds` : pas de start → null ; start seul → `{lo,hi}=start` ; start+end ordonné ; start+preview ; preview avant start (inversion) ; end prioritaire sur preview
+- `dayRangeRole` : none (pas de bornes / hors plage), single (lo===hi), start, end, in-range
+
+### `useCalendarView.test.ts` (~8, fake timers)
+- mois/année initiaux = aujourd'hui ; `goToNext`/`goToPrev` vue jours (+ roulement déc↔jan avec année) ; `goToNext`/`goToPrev` vue mois (année ±1) ; `selectMonth` ; `syncToIso` valide / null
+
+### `Date.test.ts`
+Inchangé — doit rester vert (filet du refacto).
+
+### `DateRange.test.ts` (~18)
+- Rendu : label, icône, `"19/05/2026 - 25/05/2026"` si modelValue, champ vide sinon
+- Ouverture popover, vue sur le mois du `start`
+- 1er clic → pas d'émission ; 2e clic → émet `{start,end}` + ferme
+- 2e clic avant le 1er → auto-inversion (start ≤ end)
+- Même jour ×2 → `{start:x, end:x}`
+- 3e clic → repart sur un nouveau start (pas d'émission avant le 2e)
+- Hover pendant sélection → `data-range-role="in-range"` sur jours intermédiaires ; pas de preview hors sélection
+- Rôles : `start`/`end`/`in-range` corrects via `data-range-role`
+- Clic dehors pendant sélection → annulation, `modelValue` inchangé
+- `clear` → émet `null`
+- min/max → jours hors bornes non cliquables
+- a11y : `aria-invalid` sur error
+
+### Story `dateRange.story.vue`

+# MalioDateWeek — Design Spec
+
+Composant de sélection d'une **semaine ISO complète** (lundi→dimanche) via le shell calendrier partagé. Troisième brique de la famille temporelle.
+
+**Ticket :** MUI-33 (suite)
+**Branche :** `feature/MUI-33-developper-le-composant-datepicker`
+**Specs liées :** `2026-05-19-datepicker-design.md`, `2026-05-20-daterange-design.md`
+
+## Périmètre
+
+Sélection d'une semaine entière en **un clic** (sur n'importe quel jour OU le numéro de semaine). Visuellement : la ligne de la semaine se surligne en pilule `bg-m-primary-light` (lundi arrondi gauche, dimanche arrondi droit), exactement comme une plage `DateRange` figée lun→dim. Survol = aperçu de la semaine. La cellule n° de la semaine sélectionnée passe en `bg-m-primary` (repère).
+
+**Inclus :** clic jour/n° → semaine, hover de semaine, surlignage pilule, repère n° semaine, bornes `min`/`max` (semaine sélectionnable si elle chevauche), effacement, vue mois conservée.
+
+**Reporté :** deux mois, saisie/navigation clavier.
+
+## Donnée retournée
+
+`modelValue: string | null` au format **ISO 8601 semaine `YYYY-Www`** (ex. `"2026-W21"`), comme l'`<input type="week">` natif. L'année est l'**année ISO de numérotation** (peut différer de l'année calendaire aux bords d'année). Affichage humain dans le champ : `"Semaine 21 (18/05 → 24/05/2026)"` (le `modelValue` reste `2026-W21`).
+
+## Architecture (Approche 1 — réutilisation du rendu plage)
+
+Une semaine sélectionnée **est** une plage lundi→dimanche : on réutilise le rendu pilule de `MonthGrid` (mode plage) en passant les bornes de la semaine active. Les events `select`/`hover` (jour) sont réutilisés ; l'enveloppe `DateWeek` mappe jour → semaine.

+```
+
+- Algo ISO 8601 : jeudi de la semaine pour l'année de numérotation ; lundi de la semaine contenant le 4 janvier = semaine 1.
+- `formatWeekDisplay` : `Semaine {n° sans zéro} ({JJ/MM lundi} → {JJ/MM/AAAA dimanche})`, réutilise `formatIsoToDisplay`.
+- Cas pièges testés : `2025-12-31` → `2026-W01`, `2027-01-01` → `2026-W53`, `2026-01-01` → `2026-W01`.
+
+## `MonthGrid.vue` — ajouts additifs
+
+Nouvelles props optionnelles (n'altèrent pas les modes simple/plage) :
+```ts
+interactiveWeekNumber?: boolean   // défaut false
+markedWeekStart?: string | null   // défaut null — lundi de la semaine repère
+```
+
+Quand `interactiveWeekNumber === true` :
+- La cellule n° de semaine devient un `<button>` : `@click` émet `select(week.days[0].isoDate)`, `@mouseenter` émet `hover(week.days[0].isoDate)`. `:disabled` si `!weekSelectable`, où `weekSelectable = week.days.some(d => inRange(d.isoDate))`. `cursor-pointer` si sélectionnable.
+- Repère : si `week.days[0].isoDate === markedWeekStart`, la cellule n° passe en `bg-m-primary text-white` (au lieu de `bg-m-primary-light`).
+
+Toujours (inoffensif hors mode semaine) : la cellule n° porte `:data-week-start="week.days[0].isoDate"` et `:data-marked="week.days[0].isoDate === markedWeekStart"`.
+
+Inchangé : rendu pilule des jours piloté par `rangeStart`/`rangeEnd` ; events `select`/`hover` jour ; quand `interactiveWeekNumber` est `false`, la cellule n° reste un `<div>` non cliquable (aucune régression `Date`/`DateRange`).
+
+## `DateWeek.vue` (enveloppe)
+
+**Props :** identiques à `Date` sauf `modelValue?: string | null` (`YYYY-Www`).
+**Emit :** `update:modelValue` → `string | null`.

+**`displayValue`** = `validWeek ? formatWeekDisplay(modelValue) : ''`. **`syncTo`** = `validWeek?.monday ?? null`.
+
+**Comportement (1 clic) :**

+- Sélection en un clic → `YYYY-Www` + fermeture.
+- Repère de la semaine committée conservé pendant le survol d'une autre.
+- `modelValue` invalide → traité comme `null` + warning dev.
+
+## Tests
+
+### `dateWeek.test.ts` (~14)
+- `mondayOf`/`sundayOf` : mercredi, lundi (idempotent), dimanche
+- `toIsoWeek` : nominal + bords d'année (`2025-12-31`→`2026-W01`, `2027-01-01`→`2026-W53`, `2026-01-01`→`2026-W01`)
+- `isoWeekToMonday` : `2026-W21`→`2026-05-18` ; round-trip ; invalide → null
+- `isValidIsoWeek` : valide / `W00` / `W54` / format faux
+- `formatWeekDisplay` : `2026-W21`→`"Semaine 21 (18/05 → 24/05/2026)"` ; invalide → `""`
+
+### `DateWeek.test.ts` (~14, `setSystemTime(2026-05-19)`)
+- Rendu label/icône, affichage `"Semaine ..."` si modelValue, champ vide sinon
+- Ouverture sur le mois de la semaine du modelValue
+- Clic d'un jour → émet le `YYYY-Www` de sa semaine + ferme
+- Clic du n° de semaine (`[data-test="week-number"][data-week-start="..."]`) → émet + ferme
+- Hover d'un jour → `data-range-role` start/in-range/end sur les 7 jours de la ligne ; autre ligne `none`
+- Hover du n° de semaine → même surlignage
+- Semaine committée → roles corrects + `data-marked="true"` sur la cellule n°
+- `clear` → émet `null`
+- min/max : semaine hors bornes n° désactivé + jours non cliquables ; semaine qui chevauche reste sélectionnable
+- `disabled`/`readonly` → pas d'ouverture
+- a11y : `aria-invalid` sur error
+
+`Date.test.ts` / `DateRange.test.ts` restent verts (props additives).
+
+### Story `dateWeek.story.vue`
+Default vide, semaine initiale, min/max, états (disabled/readonly/error/success), non-clearable.
+
+### Playground `.playground/pages/composant/date/dateWeek.vue`
+Comparatif Large (480px) / ERP (396px), affichage `modelValue` + bornes du champ, boutons set/reset, cas borné.
+
+## Découpage d'implémentation
+
+1. `dateWeek.ts` (purs) + tests
+2. Extension `MonthGrid.vue` (interactiveWeekNumber + markedWeekStart + data attrs)
+3. `DateWeek.vue` + `DateWeek.test.ts`
+4. Story + playground
