# Sélecteur d'année dans le calendrier — 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:** Ajouter un 3ᵉ niveau de navigation au calendrier de la famille `date/` : depuis la vue mois, recliquer sur le header ouvre un sélecteur d'année calqué sur le sélecteur de mois, avec respect des bornes `min`/`max`.

**Architecture:** Le shell partagé `internal/CalendarField.vue` orchestre l'input, le popover, le header (`CalendarHeader`) et la commutation entre les vues `days` / `months` / `years`. `MonthPicker` et le nouveau `YearPicker` sont rendus dans `CalendarField` ; la grille de jours reste fournie par chaque consommateur via slot scoped. La logique d'état vit dans deux composables (`useCalendarPopover`, `useCalendarView`) et les bornes dans des helpers purs (`dateFormat.ts`).

**Tech Stack:** Nuxt 4 layer, Vue 3 `<script setup lang="ts">`, TypeScript strict, Tailwind (palette `m-*`), `@iconify/vue`, Vitest + `@vue/test-utils` (jsdom).

## Global Constraints

- Composants : `defineOptions({name: 'MalioXxx'})` (les internes utilisent `MalioDateXxx`, sans `inheritAttrs: false` pour les pickers — calquer l'existant `MonthPicker`).
- Valeurs ISO : `min`/`max` sont des chaînes `YYYY-MM-DD` (`DateTime` les tronque via `.slice(0, 10)`).
- Tests : Vitest run mode, fichiers colocalisés `*.test.ts`, jsdom. Déterminisme via `vi.setSystemTime(new Date(2026, 4, 19))` (19 mai 2026).
- Lancer un test ciblé : `npx vitest run <chemin>`.
- Commits : Conventional Commits **avec espace avant `:`** (`feat : message (#…)`), type minuscule, **pas de scope majuscule** (préférer sans scope). Terminer par `Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>`.
- Hook pre-commit flaky (timeouts WSL2) : après 2 échecs flaky, vérifier le test ciblé à la main puis committer avec `--no-verify`.
- Ne PAS toucher / committer `nuxt.config.ts` (modif ngrok locale intentionnelle). Stager des fichiers explicites, jamais `git add -A`.
- Aucune API publique des 4 composants consommateurs ne change.

### Task 1: Helpers de plage mois/année (`dateFormat.ts`)

**Files:**
- Modify: `app/components/malio/date/composables/dateFormat.ts`
- Test: `app/components/malio/date/composables/dateFormat.test.ts`

**Interfaces:**
- Consumes: rien.
- Produces:
  - `isMonthInRange(year: number, month: number, min?: string, max?: string): boolean` (month 0-11)
  - `isYearInRange(year: number, min?: string, max?: string): boolean`

- [ ] **Step 1: Write the failing tests**

Ajouter dans `dateFormat.test.ts` — l'import en tête devient :
```ts
import {formatIsoToDisplay, isDateInRange, isMonthInRange, isValidIso, isYearInRange, parseDisplayToIso} from './dateFormat'
```
Puis ajouter ces deux blocs `describe` à l'intérieur du `describe('dateFormat', …)` (après le bloc `isDateInRange`) :
```ts
  describe('isMonthInRange', () => {
    it('returns true when no bounds are given', () => {
      expect(isMonthInRange(2026, 4)).toBe(true)
    })
    it('respects the min bound by month (inclusive)', () => {
      expect(isMonthInRange(2026, 4, '2026-05-10')).toBe(true) // mai chevauche
      expect(isMonthInRange(2026, 3, '2026-05-10')).toBe(false) // avril < mai
    })
    it('respects the max bound by month (inclusive)', () => {
      expect(isMonthInRange(2026, 4, undefined, '2026-05-31')).toBe(true)
      expect(isMonthInRange(2026, 5, undefined, '2026-05-31')).toBe(false) // juin > mai
    })
    it('disables months in years outside the range', () => {
      expect(isMonthInRange(2025, 11, '2026-05-10')).toBe(false)
      expect(isMonthInRange(2027, 0, undefined, '2026-05-31')).toBe(false)
    })
  })

  describe('isYearInRange', () => {
    it('returns true when no bounds are given', () => {
      expect(isYearInRange(2026)).toBe(true)
    })
    it('respects the min bound by year (inclusive)', () => {
      expect(isYearInRange(2026, '2026-05-10')).toBe(true)
      expect(isYearInRange(2025, '2026-05-10')).toBe(false)
    })
    it('respects the max bound by year (inclusive)', () => {
      expect(isYearInRange(2026, undefined, '2026-05-31')).toBe(true)
      expect(isYearInRange(2027, undefined, '2026-05-31')).toBe(false)
    })
  })
```

- [ ] **Step 2: Run tests to verify they fail**

Run: `npx vitest run app/components/malio/date/composables/dateFormat.test.ts`
Expected: FAIL — `isMonthInRange is not a function` / `isYearInRange is not a function`.

- [ ] **Step 3: Write minimal implementation**

Ajouter à la fin de `dateFormat.ts` :
```ts
export function isMonthInRange(year: number, month: number, min?: string, max?: string): boolean {
  const ym = `${year}-${String(month + 1).padStart(2, '0')}`
  if (min && ym < min.slice(0, 7)) return false
  if (max && ym > max.slice(0, 7)) return false
  return true
}

export function isYearInRange(year: number, min?: string, max?: string): boolean {
  if (min && year < Number(min.slice(0, 4))) return false
  if (max && year > Number(max.slice(0, 4))) return false
  return true
}
```

- [ ] **Step 4: Run tests to verify they pass**

Run: `npx vitest run app/components/malio/date/composables/dateFormat.test.ts`
Expected: PASS (tous les blocs, anciens + nouveaux).

- [ ] **Step 5: Commit**

```bash
git add app/components/malio/date/composables/dateFormat.ts app/components/malio/date/composables/dateFormat.test.ts
git commit -m "feat : helpers isMonthInRange/isYearInRange (#date-year-picker)

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>"
```

### Task 2: Machine à états 3 vues (`useCalendarPopover.ts`)

**Files:**
- Modify: `app/components/malio/date/composables/useCalendarPopover.ts`
- Test: `app/components/malio/date/composables/useCalendarPopover.test.ts`

**Interfaces:**
- Consumes: rien.
- Produces (retour du composable) : `{isOpen, viewMode, open, close, goToHigherView}` où `viewMode: Ref<'days' | 'months' | 'years'>` et `goToHigherView(): void`. **Remplace `toggleView`.**

- [ ] **Step 1: Update the failing test**

Dans `useCalendarPopover.test.ts`, remplacer le test `toggleView() switches between days and months` (lignes ~33-40) par :
```ts
  it('goToHigherView() climbs days -> months -> years and stops', () => {
    const {api} = mountHost()
    api.open()
    api.goToHigherView()
    expect(api.viewMode.value).toBe('months')
    api.goToHigherView()
    expect(api.viewMode.value).toBe('years')
    api.goToHigherView()
    expect(api.viewMode.value).toBe('years') // no-op au niveau le plus haut
  })
```
Et dans le test `close() resets isOpen and viewMode` (lignes ~42-49), remplacer `api.toggleView()` par `api.goToHigherView()`.

- [ ] **Step 2: Run test to verify it fails**

Run: `npx vitest run app/components/malio/date/composables/useCalendarPopover.test.ts`
Expected: FAIL — `api.goToHigherView is not a function`.

- [ ] **Step 3: Write minimal implementation**

Dans `useCalendarPopover.ts`, remplacer la ligne du ref et la fonction `toggleView` :
```ts
  const viewMode = ref<'days' | 'months' | 'years'>('days')
```
```ts
  const goToHigherView = () => {
    if (viewMode.value === 'days') viewMode.value = 'months'
    else if (viewMode.value === 'months') viewMode.value = 'years'
    // 'years' : niveau le plus haut, no-op
  }
```
Et le `return` :
```ts
  return {isOpen, viewMode, open, close, goToHigherView}
```

- [ ] **Step 4: Run test to verify it passes**

Run: `npx vitest run app/components/malio/date/composables/useCalendarPopover.test.ts`
Expected: PASS.

- [ ] **Step 5: Commit**

```bash
git add app/components/malio/date/composables/useCalendarPopover.ts app/components/malio/date/composables/useCalendarPopover.test.ts
git commit -m "feat : viewMode 3 niveaux + goToHigherView (#date-year-picker)

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>"
```

### Task 3: Navigation & fenêtre d'années (`useCalendarView.ts`)

**Files:**
- Modify: `app/components/malio/date/composables/useCalendarView.ts`
- Test: `app/components/malio/date/composables/useCalendarView.test.ts`

**Interfaces:**
- Consumes: `viewMode: Ref<'days' | 'months' | 'years'>` (depuis Task 2).
- Produces (retour) : `{currentMonth, currentYear, yearPageStart, goToPrev, goToNext, selectMonth, selectYear, syncToIso}` où `yearPageStart: Ref<number>` et `selectYear(y: number): void`.

- [ ] **Step 1: Write the failing tests**

Dans `useCalendarView.test.ts` : ajouter l'import de `nextTick` en tête :
```ts
import {nextTick, ref} from 'vue'
```
Puis ajouter ces tests dans le `describe('useCalendarView', …)` :
```ts
  it('paginates years by 12 in years view', () => {
    const {yearPageStart, goToNext, goToPrev} = useCalendarView(ref('years'))
    const start = yearPageStart.value
    goToNext()
    expect(yearPageStart.value).toBe(start + 12)
    goToPrev()
    expect(yearPageStart.value).toBe(start)
  })

  it('selectYear sets the current year', () => {
    const {currentYear, selectYear} = useCalendarView(ref('days'))
    selectYear(2030)
    expect(currentYear.value).toBe(2030)
  })

  it('recenters the year page on entering years view (current - 5)', async () => {
    const mode = ref<'days' | 'months' | 'years'>('days')
    const {yearPageStart} = useCalendarView(mode)
    mode.value = 'years'
    await nextTick()
    expect(yearPageStart.value).toBe(2021) // 2026 - 5
  })
```

- [ ] **Step 2: Run tests to verify they fail**

Run: `npx vitest run app/components/malio/date/composables/useCalendarView.test.ts`
Expected: FAIL — `yearPageStart` / `selectYear` undefined.

- [ ] **Step 3: Write minimal implementation**

Dans `useCalendarView.ts` :

Élargir la signature et importer `watch` :
```ts
import {ref, watch, type Ref} from 'vue'
import {isValidIso} from './dateFormat'

export function useCalendarView(viewMode: Ref<'days' | 'months' | 'years'>) {
  const today = new Date()
  const currentMonth = ref(today.getMonth())
  const currentYear = ref(today.getFullYear())
  const yearPageStart = ref(today.getFullYear() - 5)

  watch(viewMode, (mode) => {
    if (mode === 'years') yearPageStart.value = currentYear.value - 5
  })
```

Dans `goToPrev`, ajouter la branche `years` en tête :
```ts
  const goToPrev = () => {
    if (viewMode.value === 'years') {
      yearPageStart.value -= 12
      return
    }
    if (viewMode.value === 'months') {
      currentYear.value -= 1
      return
    }
    if (currentMonth.value === 0) {
      currentMonth.value = 11
      currentYear.value -= 1
    } else {
      currentMonth.value -= 1
    }
  }
```

Dans `goToNext`, idem :
```ts
  const goToNext = () => {
    if (viewMode.value === 'years') {
      yearPageStart.value += 12
      return
    }
    if (viewMode.value === 'months') {
      currentYear.value += 1
      return
    }
    if (currentMonth.value === 11) {
      currentMonth.value = 0
      currentYear.value += 1
    } else {
      currentMonth.value += 1
    }
  }
```

Ajouter `selectYear` après `selectMonth` :
```ts
  const selectYear = (y: number) => {
    currentYear.value = y
  }
```

Mettre à jour le `return` :
```ts
  return {currentMonth, currentYear, yearPageStart, goToPrev, goToNext, selectMonth, selectYear, syncToIso}
```

- [ ] **Step 4: Run tests to verify they pass**

Run: `npx vitest run app/components/malio/date/composables/useCalendarView.test.ts`
Expected: PASS (anciens + nouveaux).

- [ ] **Step 5: Commit**

```bash
git add app/components/malio/date/composables/useCalendarView.ts app/components/malio/date/composables/useCalendarView.test.ts
git commit -m "feat : pagination des années + selectYear + recentrage (#date-year-picker)

### Task 4: Header contextuel (`CalendarHeader.vue`)

**Files:**
- Modify: `app/components/malio/date/internal/CalendarHeader.vue`

**Interfaces:**
- Consumes: `viewMode`, `currentMonth`, `currentYear`, `yearPageStart` (props).
- Produces: émet `prev` / `next` / `toggle-view` (inchangé). En vue `years`, le bouton libellé n'émet pas `toggle-view` et ne montre pas le chevron-bas.

> Pas de test colocalisé pour `CalendarHeader` (l'existant n'en a pas) — vérifié via l'e2e en Task 8. Ce Task est purement implémentation ; pas de cycle test propre, donc on le commit avec son cycle de vérification = build/lint + e2e en Task 8. Le step de vérif ci-dessous est un contrôle visuel du diff.

- [ ] **Step 1: Implement the contextual label and years behavior**

Remplacer le `<template>` par :
```vue
<template>
  <div class="flex h-[36px] justify-between border-b border-black/60 mb-3">
    <button
      type="button"
      data-test="header-prev"
      class="ml-2 flex self-start rounded"
      :aria-label="prevLabel"
      @click="emit('prev')"
    >
      <Icon
        icon="mdi:chevron-left"
        :width="25"
        :height="25"
      />
    </button>

    <button
      type="button"
      data-test="header-toggle"
      class="flex gap-1 rounded text-base font-medium"
      @click="viewMode !== 'years' && emit('toggle-view')"
    >
      <span class="mt-[2px]">{{ label }}</span>
      <Icon
        v-if="viewMode !== 'years'"
        icon="mdi:chevron-down"
        :width="25"
        :height="25"
      />
    </button>

    <button
      type="button"
      data-test="header-next"
      class="mr-2 flex self-start rounded"
      :aria-label="nextLabel"
      @click="emit('next')"
    >
      <Icon
        icon="mdi:chevron-right"
        :width="25"
        :height="25"
      />
    </button>
  </div>
</template>
```

Dans le `<script setup>` : élargir le type `viewMode`, ajouter `yearPageStart`, et calculer `label` + `prevLabel` + `nextLabel` :
```ts
const props = defineProps<{
  viewMode: 'days' | 'months' | 'years'
  currentMonth: number
  currentYear: number
  yearPageStart: number
}>()
```
```ts
const label = computed(() => {
  if (props.viewMode === 'years') return `${props.yearPageStart} – ${props.yearPageStart + 11}`
  if (props.viewMode === 'months') return `${props.currentYear}`
  const name = monthsLong[props.currentMonth]
  return `${name.charAt(0).toUpperCase()}${name.slice(1)} ${props.currentYear}`
})

const prevLabel = computed(() =>
  props.viewMode === 'days' ? 'Mois précédent'
    : props.viewMode === 'months' ? 'Année précédente'
      : 'Période précédente',
)
const nextLabel = computed(() =>
  props.viewMode === 'days' ? 'Mois suivant'
    : props.viewMode === 'months' ? 'Année suivante'
      : 'Période suivante',
)
```
(Supprimer les anciens `:aria-label` ternaires inline du template — remplacés par `prevLabel`/`nextLabel`.)

- [ ] **Step 2: Lint the file**

Run: `npx eslint app/components/malio/date/internal/CalendarHeader.vue`
Expected: aucune erreur.

- [ ] **Step 3: Commit**

```bash
git add app/components/malio/date/internal/CalendarHeader.vue
git commit -m "feat : header contextuel jours/mois/années (#date-year-picker)

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>"

### Task 5: Composant `YearPicker.vue` + tests

**Files:**
- Create: `app/components/malio/date/internal/YearPicker.vue`
- Test: `app/components/malio/date/internal/YearPicker.test.ts`

**Interfaces:**
- Consumes: `isYearInRange` (Task 1).
- Produces: composant `<YearPicker :page-start :selected-year? :min? :max? @select="(year:number)=>…" />`. Rend 12 boutons `data-test="year"` avec `data-year`. Conteneur `data-test="year-picker"`.

- [ ] **Step 1: Write the failing test**

Créer `app/components/malio/date/internal/YearPicker.test.ts` :
```ts
import {describe, expect, it} from 'vitest'
import {mount} from '@vue/test-utils'
import YearPicker from './YearPicker.vue'

const mountPicker = (props: {pageStart: number, selectedYear?: number, min?: string, max?: string}) =>
  mount(YearPicker, {props})

describe('MalioDateYearPicker', () => {
  it('renders 12 years from pageStart', () => {
    const wrapper = mountPicker({pageStart: 2021})
    const years = wrapper.findAll('[data-test="year"]')
    expect(years).toHaveLength(12)
    expect(years[0].attributes('data-year')).toBe('2021')
    expect(years[11].attributes('data-year')).toBe('2032')
  })

  it('emits select with the clicked year', async () => {
    const wrapper = mountPicker({pageStart: 2021})
    await wrapper.get('[data-test="year"][data-year="2026"]').trigger('click')
    expect(wrapper.emitted('select')?.[0]).toEqual([2026])
  })

  it('disables years outside [min, max] and does not emit', async () => {
    const wrapper = mountPicker({pageStart: 2021, min: '2025-01-01', max: '2027-12-31'})
    const out = wrapper.get('[data-test="year"][data-year="2024"]')
    expect(out.attributes('disabled')).toBeDefined()
    await out.trigger('click')
    expect(wrapper.emitted('select')).toBeUndefined()
  })

  it('highlights the selected year', () => {
    const wrapper = mountPicker({pageStart: 2021, selectedYear: 2026})
    const span = wrapper.get('[data-test="year"][data-year="2026"] span')
    expect(span.classes()).toContain('bg-m-primary')
  })
})
```

- [ ] **Step 2: Run test to verify it fails**

Run: `npx vitest run app/components/malio/date/internal/YearPicker.test.ts`
Expected: FAIL — impossible de résoudre `./YearPicker.vue`.

- [ ] **Step 3: Write the component**

Créer `app/components/malio/date/internal/YearPicker.vue` :
```vue
<template>
  <div
    data-test="year-picker"
    class="grid grid-cols-3 gap-3"
  >
    <button
      v-for="year in years"
      :key="year"
      type="button"
      data-test="year"
      :data-year="year"
      :disabled="!isYearInRange(year, min, max)"
      :aria-disabled="!isYearInRange(year, min, max)"
      class="flex h-[45px] w-full items-center justify-center"
      :class="isYearInRange(year, min, max) ? 'cursor-pointer' : 'cursor-not-allowed'"
      @click="emit('select', year)"
    >
      <span
        class="flex h-[30px] w-full items-center justify-center rounded text-sm transition-colors duration-100"
        :class="year === selectedYear
          ? 'bg-m-primary text-white'
          : isYearInRange(year, min, max)
            ? 'text-black hover:bg-m-primary/10'
            : 'text-m-muted/30'"
      >
        {{ year }}
      </span>
    </button>
  </div>
</template>

<script setup lang="ts">
import {computed} from 'vue'
import {isYearInRange} from '../composables/dateFormat'

defineOptions({name: 'MalioDateYearPicker'})

const props = defineProps<{
  pageStart: number
  selectedYear?: number
  min?: string
  max?: string
}>()

const emit = defineEmits<{(e: 'select', year: number): void}>()

const years = computed(() => Array.from({length: 12}, (_, i) => props.pageStart + i))
</script>
```

> Note : `@click` émet toujours, mais un `<button disabled>` ne déclenche pas l'événement clic dans jsdom/navigateur — le test « does not emit » le valide.

- [ ] **Step 4: Run test to verify it passes**

Run: `npx vitest run app/components/malio/date/internal/YearPicker.test.ts`
Expected: PASS.

- [ ] **Step 5: Commit**

```bash
git add app/components/malio/date/internal/YearPicker.vue app/components/malio/date/internal/YearPicker.test.ts
git commit -m "feat : composant YearPicker avec bornage min/max (#date-year-picker)

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>"
```

### Task 6: Bornage min/max du `MonthPicker` + tests

**Files:**
- Modify: `app/components/malio/date/internal/MonthPicker.vue`
- Test (create): `app/components/malio/date/internal/MonthPicker.test.ts`

**Interfaces:**
- Consumes: `isMonthInRange` (Task 1).
- Produces: `<MonthPicker :selected-month? :current-year :min? :max? @select="(month:number)=>…" />`. `currentYear` devient **requis** (nécessaire pour borner les mois).

- [ ] **Step 1: Write the failing test**

Créer `app/components/malio/date/internal/MonthPicker.test.ts` :
```ts
import {describe, expect, it} from 'vitest'
import {mount} from '@vue/test-utils'
import MonthPicker from './MonthPicker.vue'

const mountPicker = (props: {currentYear: number, selectedMonth?: number, min?: string, max?: string}) =>
  mount(MonthPicker, {props})

describe('MalioDateMonthPicker', () => {
  it('renders 12 months', () => {
    const wrapper = mountPicker({currentYear: 2026})
    expect(wrapper.findAll('[data-test="month"]')).toHaveLength(12)
  })

  it('emits select with the clicked month index', async () => {
    const wrapper = mountPicker({currentYear: 2026})
    await wrapper.get('[data-test="month"][data-month="0"]').trigger('click')
    expect(wrapper.emitted('select')?.[0]).toEqual([0])
  })

  it('disables months before min in the current year and does not emit', async () => {
    const wrapper = mountPicker({currentYear: 2026, min: '2026-05-01'})
    const april = wrapper.get('[data-test="month"][data-month="3"]')
    expect(april.attributes('disabled')).toBeDefined()
    await april.trigger('click')
    expect(wrapper.emitted('select')).toBeUndefined()
  })

  it('disables months after max in the current year', () => {
    const wrapper = mountPicker({currentYear: 2026, max: '2026-05-31'})
    expect(wrapper.get('[data-test="month"][data-month="5"]').attributes('disabled')).toBeDefined()
    expect(wrapper.get('[data-test="month"][data-month="4"]').attributes('disabled')).toBeUndefined()
  })
})
```

- [ ] **Step 2: Run test to verify it fails**

Run: `npx vitest run app/components/malio/date/internal/MonthPicker.test.ts`
Expected: FAIL — le mois avril n'est pas désactivé (`disabled` undefined).

- [ ] **Step 3: Update the component**

Remplacer `MonthPicker.vue` par :
```vue
<template>
  <div
    data-test="month-picker"
    class="grid grid-cols-3 gap-3"
  >
    <button
      v-for="(name, index) in months"
      :key="name"
      type="button"
      data-test="month"

### Task 7: Câblage `CalendarField.vue`

**Files:**
- Modify: `app/components/malio/date/internal/CalendarField.vue`

**Interfaces:**
- Consumes: `useCalendarPopover` (`goToHigherView`), `useCalendarView` (`yearPageStart`, `selectYear`), `CalendarHeader` (prop `yearPageStart`), `MonthPicker` (props `currentYear`/`min`/`max`), `YearPicker` (Task 5).
- Produces: `CalendarField` accepte les props `min?: string` et `max?: string` ; rend les 3 vues.

> Vérifié via l'e2e en Task 8 (pas de test colocalisé propre à `CalendarField`). Steps = implémentation + lint, le cycle test rouge/vert vit en Task 8.

- [ ] **Step 1: Add min/max props**

Dans le bloc `defineProps`, ajouter `min` et `max` (après `reserveMessageSpace?: boolean`) :
```ts
    reserveMessageSpace?: boolean
    min?: string
    max?: string
```
Et dans `withDefaults({...})`, après `reserveMessageSpace: true,` :
```ts
    reserveMessageSpace: true,
    min: undefined,
    max: undefined,
```

- [ ] **Step 2: Import YearPicker and update composable destructuring**

Après `import MonthPicker from './MonthPicker.vue'` :
```ts
import YearPicker from './YearPicker.vue'
```
Remplacer les deux lignes de destructuration (≈218-219) :
```ts
const {isOpen, viewMode, open, close: closePopover, goToHigherView} = useCalendarPopover(root)
const {currentMonth, currentYear, yearPageStart, goToPrev, goToNext, selectMonth, selectYear, syncToIso} = useCalendarView(viewMode)
```

- [ ] **Step 3: Update the popover template**

Remplacer le bloc `<CalendarHeader>` + `<slot>` + `<MonthPicker>` (≈85-103) par :
```vue
        <CalendarHeader
          :view-mode="viewMode"
          :current-month="currentMonth"
          :current-year="currentYear"
          :year-page-start="yearPageStart"
          @prev="goToPrev"
          @next="goToNext"
          @toggle-view="goToHigherView"
        />
        <slot
          v-if="viewMode === 'days'"
          :current-month="currentMonth"
          :current-year="currentYear"
          :close="closePopover"
        />
        <MonthPicker
          v-else-if="viewMode === 'months'"
          :selected-month="currentMonth"
          :current-year="currentYear"
          :min="min"
          :max="max"
          @select="onSelectMonth"
        />
        <YearPicker
          v-else
          :page-start="yearPageStart"
          :selected-year="currentYear"
          :min="min"
          :max="max"
          @select="onSelectYear"
        />
```

- [ ] **Step 4: Update handlers**

`goToHigherView` ne sert qu'au header (zoom arrière). À la **sélection**, on redescend d'un niveau. `useCalendarPopover` n'expose pas de setter de vue, mais `viewMode` est un `ref` déstructuré et donc directement mutable. Remplacer `onSelectMonth` (≈324-327) par les deux handlers suivants :
```ts
const onSelectMonth = (m: number) => {
  selectMonth(m)
  viewMode.value = 'days'
}

const onSelectYear = (y: number) => {
  selectYear(y)
  viewMode.value = 'months'
}
```

- [ ] **Step 5: Lint**

Run: `npx eslint app/components/malio/date/internal/CalendarField.vue`
Expected: aucune erreur (notamment, `viewMode` est bien mutable car c'est un `ref`).

- [ ] **Step 6: Commit**

```bash
git add app/components/malio/date/internal/CalendarField.vue
git commit -m "feat : intégration du sélecteur d'année dans CalendarField (#date-year-picker)

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>"
```

### Task 8: Binder min/max chez les consommateurs + e2e

**Files:**
- Modify: `app/components/malio/date/Date.vue`
- Modify: `app/components/malio/date/DateRange.vue`
- Modify: `app/components/malio/date/DateTime.vue`
- Modify: `app/components/malio/date/DateWeek.vue`
- Test: `app/components/malio/date/Date.test.ts`

**Interfaces:**
- Consumes: `CalendarField` props `min`/`max` (Task 7).
- Produces: les 4 composants propagent leurs bornes au popover. API publique inchangée.

- [ ] **Step 1: Write the failing e2e test**

Dans `Date.test.ts`, à l'intérieur du `describe('vue mois', …)` (ou un nouveau `describe('vue années')`), ajouter :
```ts
  describe('vue années', () => {
    it('opens the year picker on second header toggle', async () => {
      const wrapper = mountDate()
      await wrapper.get('[data-test="date-input"]').trigger('click')
      await wrapper.get('[data-test="header-toggle"]').trigger('click') // -> mois
      await wrapper.get('[data-test="header-toggle"]').trigger('click') // -> années
      expect(wrapper.find('[data-test="year-picker"]').exists()).toBe(true)
      expect(wrapper.get('[data-test="header-toggle"]').text()).toContain('2021 – 2032')
    })

    it('navigates days -> months -> years -> months -> days', async () => {
      const wrapper = mountDate()
      await wrapper.get('[data-test="date-input"]').trigger('click')
      await wrapper.get('[data-test="header-toggle"]').trigger('click')
      await wrapper.get('[data-test="header-toggle"]').trigger('click')
      await wrapper.get('[data-test="year"][data-year="2024"]').trigger('click') // -> mois 2024
      expect(wrapper.find('[data-test="month-picker"]').exists()).toBe(true)
      expect(wrapper.get('[data-test="header-toggle"]').text()).toContain('2024')
      await wrapper.get('[data-test="month"][data-month="0"]').trigger('click') // -> jours
      expect(wrapper.find('[data-test="month-picker"]').exists()).toBe(false)
      expect(wrapper.get('[data-test="header-toggle"]').text()).toContain('Janvier 2024')
      expect(wrapper.emitted('update:modelValue')).toBeUndefined()
    })

    it('paginates the year window with chevrons', async () => {
      const wrapper = mountDate()
      await wrapper.get('[data-test="date-input"]').trigger('click')
      await wrapper.get('[data-test="header-toggle"]').trigger('click')
      await wrapper.get('[data-test="header-toggle"]').trigger('click')
      await wrapper.get('[data-test="header-next"]').trigger('click')
      expect(wrapper.get('[data-test="header-toggle"]').text()).toContain('2033 – 2044')
    })

    it('greys out years outside [min, max]', async () => {
      const wrapper = mountDate({min: '2025-01-01', max: '2027-12-31'})
      await wrapper.get('[data-test="date-input"]').trigger('click')
      await wrapper.get('[data-test="header-toggle"]').trigger('click')
      await wrapper.get('[data-test="header-toggle"]').trigger('click')
      expect(wrapper.get('[data-test="year"][data-year="2024"]').attributes('disabled')).toBeDefined()
      expect(wrapper.get('[data-test="year"][data-year="2026"]').attributes('disabled')).toBeUndefined()
    })
  })
```

- [ ] **Step 2: Run test to verify it fails**

Run: `npx vitest run app/components/malio/date/Date.test.ts`
Expected: FAIL — `year-picker` introuvable (Date.vue ne passe pas encore `min`/`max` à `CalendarField`).

- [ ] **Step 3: Bind min/max on each consumer's `<CalendarField>`**

Dans `Date.vue`, `DateRange.vue`, `DateWeek.vue` : ajouter sur la balise racine `<CalendarField …>` (au même niveau que les autres props, ex. après `:readonly="readonly"`) :
```vue
    :min="min"
    :max="max"
```
Dans `DateTime.vue` : ajouter (les bornes y sont des `YYYY-MM-DDTHH:MM`, tronquer à la date) :
```vue
    :min="min?.slice(0, 10)"
    :max="max?.slice(0, 10)"
```

- [ ] **Step 4: Run test to verify it passes**

Run: `npx vitest run app/components/malio/date/Date.test.ts`
Expected: PASS (anciens + nouveaux).

- [ ] **Step 5: Run the whole date suite (non-régression)**

Run: `npx vitest run app/components/malio/date/`
Expected: PASS — `Date`, `DateRange`, `DateTime`, `DateWeek`, composables, pickers. (En cas de timeout flaky WSL2, relancer ; voir Global Constraints.)

- [ ] **Step 6: Commit**

```bash
git add app/components/malio/date/Date.vue app/components/malio/date/DateRange.vue app/components/malio/date/DateTime.vue app/components/malio/date/DateWeek.vue app/components/malio/date/Date.test.ts
git commit -m "feat : propage min/max au popover + e2e sélecteur d'année (#date-year-picker)

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>"
```

### Task 9: Documentation (`COMPONENTS.md`, `CHANGELOG.md`)

**Files:**
- Modify: `COMPONENTS.md`
- Modify: `CHANGELOG.md`

**Interfaces:**
- Consumes: comportement livré aux tasks 1-8.
- Produces: doc à jour (convention projet : maj manuelle).

- [ ] **Step 1: Locate the date section in COMPONENTS.md**

Run: `grep -nE "MalioDate|Date|calendrier|sélecteur" COMPONENTS.md | head -20`
Expected: repère la section calendrier/date. Si aucune entrée, l'ajouter à la suite des autres composants date.

- [ ] **Step 2: Document the 3-level navigation**

Ajouter (dans la section du calendrier date) une description du 3ᵉ niveau :
```markdown
Le calendrier propose trois niveaux de navigation : jours → clic sur l'en-tête →
sélecteur de mois → nouveau clic sur l'en-tête → sélecteur d'année (grille de 12 ans,
chevrons par pas de 12 ans). Les props `min`/`max` grisent les mois et les années hors
plage. Sélectionner une année revient au sélecteur de mois, sélectionner un mois revient
à la grille de jours.
```

- [ ] **Step 3: Add a CHANGELOG entry**

Sous la section non publiée (ou en tête, selon le format existant — vérifier `head -20 CHANGELOG.md`) :
```markdown
- Calendrier (Date/DateRange/DateTime/DateWeek) : sélecteur d'année (3ᵉ niveau) et
  grisage des mois/années hors `min`/`max`.
```

- [ ] **Step 4: Commit**

```bash
git add COMPONENTS.md CHANGELOG.md
git commit -m "docs : sélecteur d'année dans le calendrier (#date-year-picker)

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>"
```

## Notes de vérification finale

- Suite ciblée complète : `npx vitest run app/components/malio/date/`
- Lint global : `npm run lint`
- Vérif manuelle navigateur : **proposer** à l'utilisateur (ne pas lancer le MCP Chrome sans accord — coût tokens). Parcours : ouvrir un `MalioDate`, cliquer le header 2× → grille d'années, paginer, choisir une année puis un mois, et tester un champ avec `min`/`max` pour voir le grisage.
