fix(toasts) : auto-dismiss des notifications d'erreur apres 8 secondes

Les toasts d'erreur etaient persistants (duration force a 0) et restaient
affiches jusqu'a fermeture manuelle, ce qui pouvait empiler des messages
obsoletes a l'ecran. Aligne le comportement sur les autres types : duree
par defaut 8s (plus que warning a 6s pour laisser le temps de lire). Une
erreur critique peut toujours etre rendue persistante en passant
explicitement showError(msg, 0).

+# Machine Context Custom Fields — Backend 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.
+> **Parallel plan:** This is the backend half. The frontend plan is at `2026-04-02-machine-context-fields-frontend.md`. Both can run in parallel on separate worktrees — they share no files.
+
+**Goal:** Add `machineContextOnly` flag on `CustomField`, link FKs on `CustomFieldValue`, structure controller normalization, upsert support, clone support, and tests.
+
+**Architecture:** `CustomField.machineContextOnly` flags definitions. `CustomFieldValue` gets nullable FKs to `MachineComponentLink`/`MachinePieceLink`. The structure response returns `contextCustomFields` and `contextCustomFieldValues` per link. Upsert and clone are extended.
+
+**Tech Stack:** Symfony 8, Doctrine ORM, API Platform 4, PostgreSQL 16, PHPUnit 12
+
+**Spec:** `docs/superpowers/specs/2026-04-02-machine-context-custom-fields-design.md`

+- Modify: `src/Controller/MachineStructureController.php`
+
+- [ ] **Step 1: Add `machineContextOnly` to all normalization methods**
+
+In `normalizeCustomFields` (line 601), add to the output array at line 615:
+```php
+'machineContextOnly' => $customField->isMachineContextOnly(),
+```
+
+In `normalizeCustomFieldDefinitions` (line 838), add to the output array at line 852:
+```php
+'machineContextOnly' => $cf->isMachineContextOnly(),
+```
+
+In `normalizeCustomFieldValues` (line 861), add to the nested `customField` array at line 879:
+```php
+'machineContextOnly' => $cf->isMachineContextOnly(),
+```
+
+- [ ] **Step 2: Add `normalizeContextCustomFieldDefinitions` helper**
+
+Add a new private method after `normalizeCustomFieldValues`:
+
+```php
+private function normalizeContextCustomFieldDefinitions(Collection $customFields): array
+{
+    $items = [];
+    foreach ($customFields as $cf) {
+        if (!$cf instanceof CustomField || !$cf->isMachineContextOnly()) {

+
+    usort($items, static fn (array $a, array $b) => $a['orderIndex'] <=> $b['orderIndex']);
+
+    return $items;
+}
+```
+
+- [ ] **Step 3: Update `normalizeComponentLinks` to include context fields**
+
+In `normalizeComponentLinks` (line 622), add `$type` variable and context field keys to the returned array:

+            'composantId'              => $composant->getId(),
+            'composant'                => $this->normalizeComposant($composant),

+            'contextCustomFields'      => $type ? $this->normalizeContextCustomFieldDefinitions($type->getComponentCustomFields()) : [],
+            'contextCustomFieldValues' => $this->normalizeCustomFieldValues($link->getContextFieldValues()),
+        ];

+            'contextCustomFieldValues' => $this->normalizeCustomFieldValues($link->getContextFieldValues()),
+        ];
+    }, $links);
+}
+```
+
+- [ ] **Step 5: Run linter**
+
+```bash
+make php-cs-fixer-allow-risky

+
+## Task 5: `CustomFieldValueController` — support link-based upsert
+
+**Files:**
+- Modify: `src/Controller/CustomFieldValueController.php`
+
+- [ ] **Step 1: Inject link repositories in constructor**
+
+In the constructor (line 24), add:
+
+```php
+private readonly MachineComponentLinkRepository $machineComponentLinkRepository,
+private readonly MachinePieceLinkRepository $machinePieceLinkRepository,
+```
+
+Add use statements at the top:
+```php
+use App\Repository\MachineComponentLinkRepository;
+use App\Repository\MachinePieceLinkRepository;
+```
+
+- [ ] **Step 2: Extend `resolveTarget` to support link entities**
+
+In `resolveTarget` (line 211), the method applies `strtolower()` on entityType at line 213. The candidate loop and match block must handle this.
+
+Update the candidate list in the foreach (line 217):
+```php
+foreach (['machine', 'composant', 'piece', 'product', 'machineComponentLink', 'machinePieceLink'] as $candidate) {
+```
+
+**IMPORTANT:** The candidate loop assigns `$entityType` in camelCase, but `strtolower()` (line 213) only applies when `entityType` comes from the payload directly. Add a normalization after the loop closes (after the existing `break;` at line 226), before the empty-check at line 229:
+
+```php
+$entityType = strtolower($entityType);
+```
+
+This ensures both code paths (direct payload `entityType` and candidate loop) deliver lowercase to the match block.
+
+Update the match block (line 233) — all keys lowercase, but `resolveEntity` returns camelCase type for `applyTarget`:
+
+```php
+return match ($entityType) {
+    'machine'              => $this->resolveEntity('machine', $entityId, $this->machineRepository),
+    'composant'            => $this->resolveEntity('composant', $entityId, $this->composantRepository),
+    'piece'                => $this->resolveEntity('piece', $entityId, $this->pieceRepository),
+    'product'              => $this->resolveEntity('product', $entityId, $this->productRepository),
+    'machinecomponentlink' => $this->resolveEntity('machineComponentLink', $entityId, $this->machineComponentLinkRepository),
+    'machinepiecelink'     => $this->resolveEntity('machinePieceLink', $entityId, $this->machinePieceLinkRepository),
+    default                => $this->json(['success' => false, 'error' => 'Unsupported entity type.'], 400),
+};
+```
+
+- [ ] **Step 3: Extend `applyTarget` for link entities**
+
+Add two new cases in `applyTarget` (line 252):
+
+```php
+case 'machineComponentLink':
+    $value->setMachineComponentLink($entity);
+    $value->setComposant($entity->getComposant());
+
+    break;
+
+case 'machinePieceLink':
+    $value->setMachinePieceLink($entity);
+    $value->setPiece($entity->getPiece());
+
+    break;
+```
+
+- [ ] **Step 4: Run linter**
+
+```bash
+make php-cs-fixer-allow-risky
+```
+
+- [ ] **Step 5: Commit**

+```bash
+git add src/Controller/CustomFieldValueController.php

+## Task 6: Clone support — copy context field values
+
+**Files:**
+- Modify: `src/Controller/MachineStructureController.php` (after `cloneProductLinks`, before `flush` in `cloneMachine`)
+
+- [ ] **Step 1: Add `cloneContextFieldValues` helper method**
+
+Add after `cloneProductLinks`:
+
+```php
+/**
+ * @param array<string, MachineComponentLink> $componentLinkMap
+ * @param array<string, MachinePieceLink>     $pieceLinkMap
+ */
+private function cloneContextFieldValues(
+    array $componentLinkMap,

+        foreach ($oldLink->getContextFieldValues() as $cfv) {
+            $newValue = new CustomFieldValue();
+            $newValue->setCustomField($cfv->getCustomField());
+            $newValue->setValue($cfv->getValue());
+            $newValue->setMachineComponentLink($newLink);
+            $newValue->setComposant($newLink->getComposant());
+            $this->entityManager->persist($newValue);
+        }

+
+    foreach ($pieceLinkMap as $oldLinkId => $newLink) {
+        $oldLink = $this->machinePieceLinkRepository->find($oldLinkId);
+        if (!$oldLink) {
+            continue;
+        }
+        foreach ($oldLink->getContextFieldValues() as $cfv) {
+            $newValue = new CustomFieldValue();
+            $newValue->setCustomField($cfv->getCustomField());

+            $this->entityManager->persist($newValue);
+        }
+    }
+}
+```
+
+- [ ] **Step 2: Call from `cloneMachine` method**
+
+In `cloneMachine` (line 113), after `$this->cloneProductLinks($source, $newMachine, $componentLinkMap, $pieceLinkMap);` (line 163) and before `$this->entityManager->flush();` (line 165), add:

+# Machine Context Custom Fields — Frontend 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.
+> **Parallel plan:** This is the frontend half. The backend plan is at `2026-04-02-machine-context-fields-backend.md`. Both can run in parallel on separate worktrees — they share no files. Frontend tests requiring the API will need the backend done first.
+
+**Goal:** Add `machineContextOnly` toggle in structure editors, filter context fields from standalone pages, and display/edit them in the machine detail view.
+
+**Architecture:** Structure editors get a checkbox per field. The machine-detail transform propagates `contextCustomFields`/`contextCustomFieldValues` from the API link response onto the component/piece objects. Standalone entity views filter these out. Machine view displays them in a separate "Champs contextuels" section using the existing `CustomFieldDisplay` component, saving via upsert with the link ID.
+
+**Tech Stack:** Nuxt 4, Vue 3 Composition API, TypeScript, DaisyUI 5
+
+**Spec:** `docs/superpowers/specs/2026-04-02-machine-context-custom-fields-design.md`
+

+
+---
+
+## Task 1: Types — add `machineContextOnly`
+
+**Files:**
+- Modify: `frontend/app/shared/types/inventory.ts`
+
+- [ ] **Step 1: Add `machineContextOnly` to `ComponentModelCustomField`**
+
+In the `ComponentModelCustomField` interface (around line 14), add:
+
+```typescript
+machineContextOnly?: boolean
+```
+
+- [ ] **Step 2: Add `machineContextOnly` to `PieceModelCustomField`**
+
+In the `PieceModelCustomField` interface (around line 65), add:
+
+```typescript
+machineContextOnly?: boolean
+```
+
+- [ ] **Step 3: Commit**
+
+```bash
+cd frontend && git add app/shared/types/inventory.ts
+git commit -m "feat(custom-fields) : add machineContextOnly to custom field types"
+```
+
+---
+
+## Task 2: Structure editors — add toggle
+
+**Files:**
+- Modify: `frontend/app/components/PieceModelStructureEditor.vue:122-125`
+- Modify: `frontend/app/composables/usePieceStructureEditorLogic.ts:283-290`
+- Modify: `frontend/app/components/StructureNodeEditor.vue:121-125`
+- Modify: `frontend/app/composables/useStructureNodeCrud.ts:49-62`
+
+- [ ] **Step 1: Add toggle in `PieceModelStructureEditor.vue`**
+
+After the "Obligatoire" checkbox block (line 125, after `</div>` closing the required checkbox), add:
+
+```vue
+              <div class="flex items-center gap-2 text-xs">
+                <input v-model="field.machineContextOnly" type="checkbox" class="checkbox checkbox-xs">
+                Contexte machine uniquement
+              </div>
+```
+
+- [ ] **Step 2: Update `usePieceStructureEditorLogic.ts` — 3 functions**
+
+**a) `createEmptyField`** (line 283) — add `machineContextOnly: false` to the returned object:
+
+```typescript
+const createEmptyField = (orderIndex: number): EditorField => ({
+    uid: createUid('field'),
+    name: '',
+    type: 'text',
+    required: false,
+    optionsText: '',
+    machineContextOnly: false,
+    orderIndex,
+})
+```
+
+**b) `toEditorField`** (line 78-91) — add `machineContextOnly` to the returned object, after the `orderIndex` line (line 90):
+
+```typescript
+machineContextOnly: Boolean(input?.machineContextOnly),
+```
+
+**c) `buildPayload`** (line 160-165) — add `machineContextOnly` to the `payload` object after `orderIndex` (line 164):
+
+```typescript
+machineContextOnly: Boolean(field.machineContextOnly),
+```
+
+- [ ] **Step 3: Add toggle in `StructureNodeEditor.vue`**
+
+After the "Obligatoire" checkbox closing `</div>` (line 123) and **before** the `<textarea>` for select options (line 124), add:
+
+```vue
+                <div class="flex items-center gap-2 text-xs">
+                  <input v-model="field.machineContextOnly" type="checkbox" class="checkbox checkbox-xs">
+                  Contexte machine uniquement
+                </div>
+```
+
+- [ ] **Step 4: Update `addCustomField` in `useStructureNodeCrud.ts`**
+
+In `addCustomField` (line 49), add `machineContextOnly: false` to the pushed object (line 53-60):
+
+```typescript
+fields.push({
+    name: '',
+    type: 'text',
+    required: false,
+    optionsText: '',
+    options: [],
+    machineContextOnly: false,
+    orderIndex: nextIndex,
+})
+```
+
+- [ ] **Step 5: Run lint + typecheck**
+
+```bash
+cd frontend && npm run lint:fix && npx nuxi typecheck
+```
+
+Expected: 0 errors.
+
+- [ ] **Step 6: Commit**
+
+```bash
+cd frontend && git add .
+git commit -m "feat(custom-fields) : add machineContextOnly toggle in structure editors"
+```
+
+---
+
+## Task 3: Filter context fields on standalone pages + machine-detail transform
+
+**Files:**
+- Modify: `frontend/app/composables/useEntityCustomFields.ts:42-49`
+- Modify: `frontend/app/composables/useMachineDetailCustomFields.ts:141-154,241-256`
+
+- [ ] **Step 1: Filter `machineContextOnly` from `displayedCustomFields` in `useEntityCustomFields.ts`**
+
+Update the `displayedCustomFields` computed (line 42):
+
+```typescript
+const displayedCustomFields = computed(() =>
+  dedupeMergedFields(
+    mergeFieldDefinitionsWithValues(
+      definitionSources.value,
+      entity().customFieldValues,
+    ),
+  ).filter((field: any) => !field.machineContextOnly && !field.customField?.machineContextOnly),
+)
+```
+
+- [ ] **Step 2: Filter `machineContextOnly` from normal customFields in machine-detail transform and propagate context data**
+
+In `frontend/app/composables/useMachineDetailCustomFields.ts`:
+
+**For pieces** — In `transformCustomFields` (line 70), the returned object is built at line 141. Replace the `customFields,` line (line 143) with:
+
+```typescript
+customFields: customFields.filter((f: AnyRecord) => !f.machineContextOnly && !f.customField?.machineContextOnly),
+contextCustomFields: piece.contextCustomFields ?? [],
+contextCustomFieldValues: piece.contextCustomFieldValues ?? [],
+```
+
+**For components** — In `transformComponentCustomFields` (line 158), the returned object is built at line 241. Replace the `customFields,` line (line 243) with:
+
+```typescript
+customFields: customFields.filter((f: AnyRecord) => !f.machineContextOnly && !f.customField?.machineContextOnly),
+contextCustomFields: component.contextCustomFields ?? [],
+contextCustomFieldValues: component.contextCustomFieldValues ?? [],
+```
+
+- [ ] **Step 3: Run lint + typecheck**
+
+```bash
+cd frontend && npm run lint:fix && npx nuxi typecheck
+```
+
+Expected: 0 errors.
+
+- [ ] **Step 4: Commit**
+
+```bash
+cd frontend && git add .
+git commit -m "feat(custom-fields) : filter machineContextOnly from standalone and machine-detail views"
+```
+
+---
+
+## Task 4: Display context fields in machine view — `ComponentItem.vue`
+
+**Files:**
+- Modify: `frontend/app/components/ComponentItem.vue`
+
+Context fields are on the `component` object (set by the transform in Task 3), not as separate props.
+
+- [ ] **Step 1: Add template section**
+
+After the existing `CustomFieldDisplay` block (line 195), add:
+
+```vue
+        <!-- Context custom fields (machine-specific) -->
+        <div v-if="mergedContextFields.length" class="mt-4">
+          <h4 class="text-xs font-semibold text-base-content/70 mb-2">

+            @field-blur="updateContextCustomField"
+          />
+        </div>
+```
+
+- [ ] **Step 2: Add imports and script logic**
+
+**IMPORTANT:** `ComponentItem.vue` uses `<script setup>` WITHOUT `lang="ts"`. Do NOT use TypeScript annotations (`: any`, `: string`, etc.) in any code added to this file.
+
+Add these imports (they are NOT already present in the component):
+
+```javascript
+import { mergeFieldDefinitionsWithValues, dedupeMergedFields } from '~/shared/utils/entityCustomFieldLogic'
+import { useCustomFields } from '~/composables/useCustomFields'
+import { useToast } from '~/composables/useToast'
+```
+
+Add after the existing `useEntityCustomFields` block (around line 348):
+
+```javascript
+const { upsertCustomFieldValue } = useCustomFields()
+const { showSuccess, showError } = useToast()
+
+const mergedContextFields = computed(() => {

+    field.value ?? '',
+  )
+
+  if (result.success) {
+    showSuccess(`Champ contextuel "${field.name || field.customField?.name}" mis à jour`)
+  } else {
+    showError(`Erreur lors de la mise à jour du champ contextuel`)
+  }
+}
+```
+
+- [ ] **Step 3: Run lint + typecheck**
+
+```bash
+cd frontend && npm run lint:fix && npx nuxi typecheck
+```
+
+- [ ] **Step 4: Commit**
+
+```bash
+cd frontend && git add app/components/ComponentItem.vue

+
+## Task 5: Display context fields in machine view — `PieceItem.vue`
+
+**Files:**
+- Modify: `frontend/app/components/PieceItem.vue`
+
+- [ ] **Step 1: Add template section**

+```vue
+        <!-- Context custom fields (machine-specific) -->
+        <div v-if="mergedContextFields.length" class="mt-4">
+          <h4 class="text-xs font-semibold text-base-content/70 mb-2">

+# Custom Fields Simplification — 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:** Replace 3 parallel custom fields frontend implementations (~2900 lines, 9 files) with a single unified module (~400 lines, 2 files), then migrate all consumers.
+
+**Architecture:** One pure-logic module (`customFields.ts`) with types + helpers, one reactive composable (`useCustomFieldInputs.ts`) wrapping it. The existing API composable `useCustomFields.ts` stays as-is (it's the HTTP layer). The backend already returns a consistent format — only one minor fix needed (add `defaultValue` to serialization groups).
+
+**Tech Stack:** TypeScript, Vue 3 Composition API, Nuxt 4 auto-imports
+
+**Spec:** `docs/superpowers/specs/2026-04-04-custom-fields-simplification-design.md`
+

+
+## Task 4: Migrate shared components + standalone composables (atomic batch)
+
+**Why batched:** `CustomFieldInputGrid.vue` and `CustomFieldDisplay.vue` receive fields from the composables. Migrating them separately would cause TypeScript errors in the intermediate state. Migrate all together.
+
+**Files:**
+- Modify: `frontend/app/components/common/CustomFieldInputGrid.vue`
+- Modify: `frontend/app/components/common/CustomFieldDisplay.vue`
+- Modify: `frontend/app/composables/useComponentEdit.ts`
+- Modify: `frontend/app/composables/useComponentCreate.ts`
+- Modify: `frontend/app/composables/usePieceEdit.ts`
+
+- [ ] **Step 1: Migrate `CustomFieldInputGrid.vue`**
+
+Replace the import:
+```typescript
+// OLD
+import { fieldKey, type CustomFieldInput } from '~/shared/utils/customFieldFormUtils'
+// NEW
+import { fieldKey, type CustomFieldInput } from '~/shared/utils/customFields'
+```
+
+- [ ] **Step 2: Migrate `CustomFieldDisplay.vue`**
+
+Replace all imports from `entityCustomFieldLogic`. With the new typed `CustomFieldInput`, direct property access (`.name`, `.type`, `.options`, `.value`, `.readOnly`) replaces the `resolveFieldXxx()` wrapper functions. Read the full file and adapt the template accordingly.
+
+- [ ] **Step 3: Migrate `useComponentEdit.ts`**
+
+Read the file. Key changes:
+1. Replace `customFieldFormUtils` imports with the new module
+2. Replace the imperative `refreshCustomFieldInputs` + `buildCustomFieldInputs` pattern with `useCustomFieldInputs`
+3. Pass `selectedTypeStructure.value?.customFields` as definitions and `component.value?.customFieldValues` as values
+4. Use the `onValueCreated` callback to push new values into `component.value.customFieldValues` so the reactive source stays in sync
+5. Replace calls to `refreshCustomFieldInputs()` in watchers/fetch with calls to `refresh()` from the composable
+
+- [ ] **Step 4: Migrate `useComponentCreate.ts`**
+
+Same pattern. Definitions come from `selectedType.value?.structure?.customFields`, values are empty `[]` for creation.
+
+- [ ] **Step 5: Migrate `usePieceEdit.ts`**
+
+Same pattern. Definitions from piece type structure, values from `piece.customFieldValues`.
+
+- [ ] **Step 6: Run lint + typecheck**
+
+```bash
+cd frontend && npm run lint:fix && npx nuxi typecheck
+```
+
+- [ ] **Step 7: Verify**
+
+Open each page in the browser:
+- `/component/{id}` — check custom fields display and edit
+- `/component/create` — check custom fields with default values
+- `/pieces/{id}/edit` — check custom fields display and edit
+
+- [ ] **Step 8: Commit**
+
+```bash
+git add frontend/app/components/common/CustomFieldInputGrid.vue frontend/app/components/common/CustomFieldDisplay.vue frontend/app/composables/useComponentEdit.ts frontend/app/composables/useComponentCreate.ts frontend/app/composables/usePieceEdit.ts
+git commit -m "refactor(custom-fields) : migrate shared components and standalone composables to unified module"
+```
+
+---
+
+## Task 5: Migrate standalone pages (product + piece create)
+
+**Files:**
+- Modify: `frontend/app/pages/pieces/create.vue`
+- Modify: `frontend/app/pages/product/create.vue`
+- Modify: `frontend/app/pages/product/[id]/edit.vue`
+- Modify: `frontend/app/pages/product/[id]/index.vue`
+
+These pages import directly from `customFieldFormUtils`. Replace with the new module.
+
+- [ ] **Step 1: Read each file and identify all `customFieldFormUtils` imports**
+
+- [ ] **Step 2: For each page, replace imports**
+
+Replace:
+```typescript
+import { CustomFieldInput, normalizeCustomFieldInputs, buildCustomFieldInputs, requiredCustomFieldsFilled, saveCustomFieldValues } from '~/shared/utils/customFieldFormUtils'
+```
+With:
+```typescript
+import { type CustomFieldInput, normalizeDefinitions, mergeDefinitionsWithValues, requiredFieldsFilled } from '~/shared/utils/customFields'
+import { useCustomFieldInputs } from '~/composables/useCustomFieldInputs'
+```
+
+Adapt the logic in each page to use `useCustomFieldInputs` or the pure helpers as appropriate.
+
+- [ ] **Step 3: Run lint + typecheck**
+
+```bash
+cd frontend && npm run lint:fix && npx nuxi typecheck
+```
+
+- [ ] **Step 4: Verify**
+
+Open each page in the browser:
+- `/pieces/create` — check custom fields appear when selecting a type
+- `/product/create` — same
+- `/product/{id}/edit` — check fields display with values
+- `/product/{id}` — check read-only display
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add frontend/app/pages/pieces/create.vue frontend/app/pages/product/create.vue frontend/app/pages/product/\[id\]/edit.vue frontend/app/pages/product/\[id\]/index.vue
+git commit -m "refactor(custom-fields) : migrate product and piece pages to unified module"
+```
+
+---
+
+## Task 6: Clean category editor files (`componentStructure*.ts`)
+
+**WHY BEFORE MACHINE PAGE:** `normalizeStructureForEditor` is used by `useMachineDetailCustomFields.ts`. If we change it after migrating the machine page, the machine page would break. So clean this first.
+
+**Files:**
+- Modify: `frontend/app/shared/model/componentStructure.ts`
+- Modify: `frontend/app/shared/model/componentStructureSanitize.ts`
+- Modify: `frontend/app/shared/model/componentStructureHydrate.ts`
+
+- [ ] **Step 1: Read the three files and identify custom field code**
+
+The custom field code in these files handles the category editor (defining fields on a ModelType skeleton). It's the `sanitizeCustomFields` and `hydrateCustomFields` functions, plus custom field handling in `normalizeStructureForEditor` and `normalizeStructureForSave`.
+
+- [ ] **Step 2: Replace custom field sanitize/hydrate with the unified module**
+
+In `componentStructure.ts`, replace the custom field handling in `normalizeStructureForEditor`:
+```typescript
+// OLD
+const sanitizedCustomFields = sanitizeCustomFields(source.customFields)
+const customFields = sanitizedCustomFields.map((field) => { ... })
+// NEW
+import { mergeDefinitionsWithValues } from '~/shared/utils/customFields'
+const customFields = mergeDefinitionsWithValues(source.customFields, [])
+```
+
+**`optionsText` is now included** in `CustomFieldInput` (added in the type definition). `mergeDefinitionsWithValues` already computes `optionsText` from `options.join('\n')`, so all category editor textareas (`v-model="field.optionsText"`) will work without changes.
+
+- [ ] **Step 3: Run lint + typecheck**
+
+```bash
+cd frontend && npm run lint:fix && npx nuxi typecheck
+```
+
+- [ ] **Step 4: Verify TWO things**
+
+1. Open `/component-category/{id}/edit` — check that custom fields are displayed, can be added/removed/reordered, and save correctly.
+2. Open `/machine/{id}` — check that the machine page still works (it uses `normalizeStructureForEditor` via `useMachineDetailCustomFields.ts`).
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add frontend/app/shared/model/componentStructure.ts frontend/app/shared/model/componentStructureSanitize.ts frontend/app/shared/model/componentStructureHydrate.ts
+git commit -m "refactor(custom-fields) : clean category editor structure files"
+```
+
+---
+
+## Task 7: Migrate machine page — `MachineCustomFieldsCard`, `MachineInfoCard`, `useMachineDetailCustomFields`
+
+**Depends on:** Task 6 (category editor cleaned — `normalizeStructureForEditor` already uses new types)
+
+**Files:**
+- Modify: `frontend/app/components/machine/MachineCustomFieldsCard.vue`
+- Modify: `frontend/app/components/machine/MachineInfoCard.vue`
+- Modify: `frontend/app/composables/useMachineDetailCustomFields.ts`
+
+- [ ] **Step 1: Migrate `MachineCustomFieldsCard.vue` and `MachineInfoCard.vue`**
+
+Replace:
+```typescript
+import { formatCustomFieldValue } from '~/shared/utils/customFieldUtils'
+```
+With:
+```typescript
+import { formatValueForDisplay, type CustomFieldInput } from '~/shared/utils/customFields'
+```
+
+Replace all calls to `formatCustomFieldValue(field)` with `formatValueForDisplay(field)`.
+
+- [ ] **Step 2: Migrate `useMachineDetailCustomFields.ts` — pure custom field functions**
+
+Replace the following pure-CF functions (~168 lines) with the new module:
+
+| Old function (lines) | Replacement |
+|---|---|
+| `syncMachineCustomFields` (269-289) | `mergeDefinitionsWithValues(machine.customFields, machine.customFieldValues)` |
+| `setMachineCustomFieldValue` (291-299) | Direct property mutation on the mutable `CustomFieldInput` |
+| `updateMachineCustomField` (302-363) | `useCustomFieldInputs.update()` |
+| `saveAllMachineCustomFields` (461-511) | `useCustomFieldInputs.saveAll()` |
+| `saveAllContextCustomFields` (430-459) | Loop over link-level `useCustomFieldInputs` instances |
+
+- [ ] **Step 3: Migrate `useMachineDetailCustomFields.ts` — mixed transform functions**
+
+`transformCustomFields` (lines 71-158) and `transformComponentCustomFields` (lines 161-263) mix custom field merging with constructeur/product/document logic in a single `map()`. Refactor surgically:
+
+**Inside `transformCustomFields` map callback**, replace lines 82-106 (valueEntries + merge + dedupe + filter):
+```typescript
+// OLD: ~25 lines of valueEntries building, normalizeCustomFieldValueEntry, mergeCustomFieldValuesWithDefinitions, dedupeCustomFieldEntries
+// NEW: 2 lines
+const customFields = filterByContext(
+  mergeDefinitionsWithValues(type.customFields ?? typePiece.customFields ?? [], piece.customFieldValues ?? []),
+  'standalone',
+)

+```
+
+- [ ] **Step 5: Verify**
+
+Open a machine page (`/machine/{id}`) that has:
+- Machine-level custom fields
+- Components with regular custom fields
+- Components with machineContextOnly fields
+Check display, edit, and save for all three.
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add frontend/app/components/machine/MachineCustomFieldsCard.vue frontend/app/components/machine/MachineInfoCard.vue frontend/app/composables/useMachineDetailCustomFields.ts
+git commit -m "refactor(custom-fields) : migrate machine page to unified module"
+```
+
+---
+
+## Task 8: Migrate hierarchy components (`ComponentItem.vue`, `PieceItem.vue`)
+
+**Depends on:** Task 7 (machine page — parent pre-merges custom fields into `CustomFieldInput[]`)
+
+**Data contract:** The parent (`useMachineDetailCustomFields.transformComponentCustomFields`) already pre-merges custom fields into `component.customFields` (a `CustomFieldInput[]`). The Item components should NOT re-merge — they display the pre-merged data directly and use the API composable only for saves/updates.
+
+**Files:**
+- Modify: `frontend/app/components/ComponentItem.vue`
+- Modify: `frontend/app/components/PieceItem.vue`
+
+- [ ] **Step 1: Migrate `ComponentItem.vue`**
+
+Read the file. Replace:
+```typescript
+import { useEntityCustomFields } from '~/composables/useEntityCustomFields'
+import { resolveFieldKey, resolveFieldName, ... } from '~/shared/utils/entityCustomFieldLogic'
+```
+With:
+```typescript
+import { useCustomFields } from '~/composables/useCustomFields'
+import { fieldKey, formatValueForDisplay, hasDisplayableValue, mergeDefinitionsWithValues, type CustomFieldInput } from '~/shared/utils/customFields'
+```
+
+Key changes:
+1. **Remove `useEntityCustomFields`** — the parent already pre-merges. Use `props.component.customFields` directly (already `CustomFieldInput[]` after Task 7)
+2. **For display:** use `hasDisplayableValue(field)` and `formatValueForDisplay(field)` instead of `resolveFieldXxx()` wrappers
+3. **For edits/saves:** use `useCustomFields()` directly (the HTTP layer) instead of `useEntityCustomFields().updateCustomField`
+4. **For context fields** (`component.contextCustomFields` + `component.contextCustomFieldValues`): merge locally with `mergeDefinitionsWithValues` — these are NOT pre-merged by the parent since they come as separate arrays
+5. **Replace `resolveCustomFieldId(field)`** with `field.customFieldId` (direct property access on `CustomFieldInput`)
+6. **Replace `resolveFieldId(field)`** with `field.customFieldValueId`
+
+- [ ] **Step 2: Migrate `PieceItem.vue`**
+
+Same pattern as ComponentItem but with `entityType: 'piece'` and `props.piece.customFields`.
+
+- [ ] **Step 3: Run lint + typecheck**
+
+```bash
+cd frontend && npm run lint:fix && npx nuxi typecheck
+```
+
+- [ ] **Step 4: Verify**
+
+Open a machine page and expand components/pieces in the hierarchy. Check custom fields display correctly.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add frontend/app/components/ComponentItem.vue frontend/app/components/PieceItem.vue
+git commit -m "refactor(custom-fields) : migrate ComponentItem and PieceItem to unified module"
+```
+
+---
+
+## Task 9: Delete old files + final cleanup
+
+**Files:**
+- Delete: `frontend/app/shared/utils/entityCustomFieldLogic.ts`
+- Delete: `frontend/app/shared/utils/customFieldUtils.ts`
+- Delete: `frontend/app/shared/utils/customFieldFormUtils.ts`
+- Delete: `frontend/app/composables/useEntityCustomFields.ts`
+- Delete or rewrite: `frontend/tests/shared/customFieldFormUtils.test.ts`
+
+- [ ] **Step 1: Verify no remaining imports of old files**
+
+```bash
+cd frontend && grep -r "entityCustomFieldLogic\|customFieldUtils\|customFieldFormUtils\|useEntityCustomFields" app/ --include="*.ts" --include="*.vue" -l
+```
+
+Expected: no results (0 files).
+
+- [ ] **Step 2: Delete old files**
+
+```bash
+rm frontend/app/shared/utils/entityCustomFieldLogic.ts
+rm frontend/app/shared/utils/customFieldUtils.ts
+rm frontend/app/shared/utils/customFieldFormUtils.ts
+rm frontend/app/composables/useEntityCustomFields.ts
+rm frontend/tests/shared/customFieldFormUtils.test.ts
+```
+
+- [ ] **Step 3: Run full lint + typecheck**
+
+```bash
+cd frontend && npm run lint:fix && npx nuxi typecheck
+```
+
+Expected: 0 errors.
+
+- [ ] **Step 4: Final smoke test**
+
+Test all 4 contexts in the browser:
+1. **Machine fields** — `/machine/{id}` → machine-level custom fields
+2. **Standalone entity** — `/component/{id}` → custom fields display and edit
+3. **Machine context** — `/machine/{id}` → expand a component → machineContextOnly fields
+4. **Category editor** — `/component-category/{id}/edit` → custom field definitions
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add -A
+git commit -m "refactor(custom-fields) : delete old parallel custom field modules"
+```

+# Session 04-05 avril 2026 — Refonte UX/UI complète Inventory
+
+## Contexte
+L'utilisateur (gestionnaire) remonte que les utilisateurs novices se perdent dans l'app Inventory (gestion d'inventaire industriel : machines, composants, pièces, produits). Ils découvrent le domaine ET l'app en même temps, remplissent les machines depuis de la documentation papier/PDF.
+
+## Ce qui a été fait
+
+### 1. Analyse UX/UI complète
+- Exploration en profondeur des 65+ composants, toutes les pages, composables et patterns
+- Diagnostic : navigation top-down uniquement, pas de liens inverses, pas de breadcrumbs, navbar mélange tout, pages trop longues, mode lecture ressemble à un formulaire disabled
+- Identification de 23 améliorations organisées en 4 phases
+
+### 2. Spec rédigée
+**Fichier :** `docs/superpowers/specs/2026-04-04-ux-overhaul-design.md`
+
+23 sections couvrant :
+- Réorganisation navbar par domaine métier
+- Breadcrumbs contextuels
+- Liaisons inverses "Utilisé dans"
+- Liens cliquables dans la hiérarchie machine
+- Système d'onglets partagé (machine + composant + pièce + produit)
+- Pages catalogue unifiées (catalogue + catégories en onglets)
+- Recherche globale (**retirée** à la demande de l'utilisateur)
+- Raccourcis clavier (**retirés** à la demande)
+- Mode lecture texte brut, empty states, toasts, responsive, etc.

+
+## Bugs découverts et corrigés en cours de route
+
+| Bug | Cause | Fix |
+|-----|-------|-----|
+| `<script setup>` sans `lang="ts"` | Agents ont ajouté `as string` dans des fichiers JS | Ajouté `lang="ts"` sur ComponentItem, PieceItem, machine/[id] |
+| `Cannot access 'selectedType' before initialization` | Bug pré-existant dans usePieceEdit.ts — `resolvedStructure` utilisait `selectedType` avant sa déclaration | Déplacé `resolvedStructure` avant `useCustomFieldInputs` |
+| `CommonEmptyState` non résolu | `pathPrefix: false` dans nuxt.config → les composants dans `common/` s'importent sans préfixe | Renommé `CommonEmptyState` → `EmptyState`, `CommonUsedInSection` → `UsedInSection` |
+| `/api/constructeurs/stats` retourne 404 | Route API Platform `/api/constructeurs/{id}` matchait "stats" comme un {id} | Ajouté `priority: 1` sur la route bulk stats |
+| Compteurs fournisseurs tous à 0 | Tables `*_constructeur_links` vides — liens jamais migrés depuis les tables legacy M2M | Restauré depuis backup + créé migration Doctrine |
+| Pages `/catalogues/*` manquantes sur le disque | Fichiers committés par agents mais perdus dans le working tree (confusion `frontend/` vs `app/`) | Restauré depuis git history |
+
+## Problème de données découvert
+
+Les **liens constructeur ↔ entités** n'avaient jamais été migrés des anciennes tables ManyToMany (`_composantconstructeurs`, `_piececonstructeurs`) vers les nouvelles tables de liens (`*_constructeur_links`). Ce problème est **pré-existant** au refactoring UX.
+
+### Données restaurées en local
+- 3 liens composant-constructeur
+- 23 liens pièce-constructeur (dont 6 Limatech remappé avec le nouvel ID)
+
+### Données irrémédiablement perdues (entités supprimées)
+- **Convoyeur à Bande** → était lié à Brillaud + Bühler
+- **Sangle E12** → était liée à NETCO
+- **Arbre du tambour tête E6** → était lié à Dexis
+
+### Migrations créées pour la prod
+1. `migrations/Version20260405_MigrateConstructeurLinks.php` — copie depuis les tables legacy M2M (si elles existent)
+2. `migrations/Version20260405_RestoreConstructeurLinksFromBackup.php` — fallback : insère directement les données du backup (3), nettoie les orphelins
+
+**Pour restaurer en prod :** `php bin/console doctrine:migrations:migrate`

+# Machine Context Custom Fields
+
+**Date** : 2026-04-02
+**Statut** : Validé
+
+## Objectif
+
+Permettre de définir des champs personnalisés sur un ModelType (catégorie de pièce/composant) qui ne s'affichent et ne sont remplissables que lorsque l'item est lié à une machine. Les valeurs sont propres au lien machine (une même pièce dans deux machines peut avoir des valeurs différentes).
+
+## Périmètre
+
+- **Entités concernées** : Composants et Pièces (pas Produits)
+- **Définition** : Sur le ModelType, avec un flag `machineContextOnly`
+- **Valeurs** : Stockées par lien (`MachineComponentLink` / `MachinePieceLink`)
+- **Affichage** : Uniquement dans la vue machine, pas sur les fiches autonomes
+
+## Architecture
+
+### Approche retenue
+
+Extension des entités existantes `CustomField` et `CustomFieldValue` avec :
+- Un flag de filtrage sur la définition
+- Des FK vers les entités de lien pour les valeurs
+
+### Alternatives écartées
+
+- **Entités séparées** (`MachineContextField` / `MachineContextFieldValue`) — trop de duplication de logique
+- **JSON sur les liens** — contraire au projet de normalisation JSON→tables en cours
+
+## Backend
+
+### 1. Entité `CustomField`
+
+Nouveau champ :
+
+```php
+#[ORM\Column(type: 'boolean', options: ['default' => false])]
+#[Groups(['customField:read', 'customField:write'])]
+private bool $machineContextOnly = false;
+```
+
+Getter/setter associés.
+
+### 2. Entité `CustomFieldValue`
+
+Nouvelles FK nullable :
+
+```php
+#[ORM\ManyToOne(targetEntity: MachineComponentLink::class, inversedBy: 'contextFieldValues')]
+#[ORM\JoinColumn(nullable: true)]
+private ?MachineComponentLink $machineComponentLink = null;
+
+#[ORM\ManyToOne(targetEntity: MachinePieceLink::class, inversedBy: 'contextFieldValues')]
+#[ORM\JoinColumn(nullable: true)]
+private ?MachinePieceLink $machinePieceLink = null;
+```
+
+Contrainte métier : quand `machineComponentLink` est set, `composant` reste aussi set (pour faciliter les queries par composant). Idem pour `machinePieceLink` + `piece`.
+
+### 3. Entités `MachineComponentLink` / `MachinePieceLink`
+
+Nouvelle collection :
+
+```php
+#[ORM\OneToMany(targetEntity: CustomFieldValue::class, mappedBy: 'machineComponentLink', cascade: ['persist', 'remove'], orphanRemoval: true)]
+private Collection $contextFieldValues;
+```
+
+Idem sur `MachinePieceLink` avec `mappedBy: 'machinePieceLink'`.
+
+### 4. Migration
+
+```sql
+ALTER TABLE custom_field ADD machine_context_only BOOLEAN DEFAULT false NOT NULL;
+
+ALTER TABLE custom_field_value ADD machine_component_link_id VARCHAR(36) DEFAULT NULL;
+ALTER TABLE custom_field_value ADD machine_piece_link_id VARCHAR(36) DEFAULT NULL;
+
+ALTER TABLE custom_field_value
+    ADD CONSTRAINT fk_cfv_machine_component_link
+    FOREIGN KEY (machine_component_link_id) REFERENCES machine_component_link(id) ON DELETE CASCADE;
+
+ALTER TABLE custom_field_value
+    ADD CONSTRAINT fk_cfv_machine_piece_link
+    FOREIGN KEY (machine_piece_link_id) REFERENCES machine_piece_link(id) ON DELETE CASCADE;
+
+CREATE INDEX idx_cfv_machine_component_link ON custom_field_value(machine_component_link_id);
+CREATE INDEX idx_cfv_machine_piece_link ON custom_field_value(machine_piece_link_id);
+```
+
+### 5. `MachineStructureController`
+
+Dans `normalizeComposant()` et `normalizePiece()` :
+- Récupérer les `CustomField` du ModelType où `machineContextOnly = true`
+- Récupérer les `CustomFieldValue` liées au lien via `machineComponentLink` / `machinePieceLink`
+- Ajouter dans la réponse :
+
+```json
+{
+  "contextCustomFields": [{ "id": "...", "name": "...", "type": "...", ... }],
+  "contextCustomFieldValues": [{ "id": "...", "value": "...", "customField": {...} }]
+}
+```
+
+Séparé des `customFields` / `customFieldValues` globaux existants.
+
+### 6. `CustomFieldValueController`
+
+L'upsert existant est étendu pour accepter `machineComponentLink` ou `machinePieceLink` dans le body. Le controller vérifie que si le `CustomField` a `machineContextOnly = true`, un lien machine est obligatoire.
+
+### 7. Clonage machine
+
+`MachineStructureController::cloneCustomFields()` doit aussi cloner les `contextFieldValues` des liens, en les rattachant aux nouveaux liens créés lors du clone.
+
+## Frontend
+
+### 1. Page ModelType — Définition des champs
+
+Dans l'UI d'édition des custom fields d'un ModelType, ajouter un **toggle/checkbox** "Contexte machine uniquement" sur chaque définition de champ. Cela set `machineContextOnly: true` lors de la sauvegarde.
+
+Concerne les custom fields des catégories COMPONENT et PIECE (pas PRODUCT, hors périmètre).
+
+### 2. Vue machine — `ComponentItem.vue` / `PieceItem.vue`
+
+Nouvelle section "Champs contextuels" affichée sous les custom fields existants :
+- Reçoit `contextCustomFields` et `contextCustomFieldValues` en props
+- Réutilise le composant `CustomFieldDisplay.vue` existant
+- Mode édition : sur blur/change, appel upsert via `CustomFieldValueController` avec le `machineComponentLinkId` ou `machinePieceLinkId`
+
+### 3. Fiches autonomes pièce/composant
+
+Filtrer les champs `machineContextOnly = true` pour ne pas les afficher :
+- Dans `useEntityCustomFields` : exclure ces champs du `displayedCustomFields`
+- Dans `useMachineDetailCustomFields` : séparer les champs normaux des champs contextuels
+
+### 4. Transformation des données (`useMachineDetailCustomFields`)
+
+`transformComponentCustomFields()` et `transformCustomFields()` :
+- Extraire `contextCustomFields` / `contextCustomFieldValues` depuis la réponse structure
+- Les passer en propriétés séparées sur l'objet transformé
+
+## Tests
+
+### Backend
+- Test unitaire : `CustomField` avec `machineContextOnly = true` est correctement sérialisé
+- Test API : upsert d'un `CustomFieldValue` avec `machineComponentLink` fonctionne
+- Test API : upsert d'un `CustomFieldValue` contextuel sans lien machine retourne une erreur
+- Test API : `/api/machines/{id}/structure` retourne les `contextCustomFields` et `contextCustomFieldValues`
+- Test API : clone machine copie les valeurs contextuelles
+
+### Frontend
+- Typecheck : 0 erreurs après modifications
+- Vérification manuelle : les champs contextuels apparaissent dans la vue machine
+- Vérification manuelle : les champs contextuels n'apparaissent pas sur les fiches autonomes

+# Custom Fields Simplification — Design Spec
+
+**Date:** 2026-04-04
+**Scope:** Backend minor cleanup + Frontend unification of the custom fields system
+**Constraint:** Everything must work after — progressive migration with verification at each step
+
+## Problem
+
+The custom fields system has grown into 3 parallel frontend implementations (~2900 lines across 9 files) due to accumulated defensive code. This caused data bugs (orphaned fields, lost linkage) and makes every change risky.
+
+## 4 Custom Field Contexts
+
+1. **Machine** — fields defined directly on the machine (`CustomField.machineid` FK), values on machine
+2. **Standalone entity** — fields defined in ModelType (category), values on composant/piece/product. Visible when opening the entity directly
+3. **Machine context** — fields with `machineContextOnly=true` defined in ModelType, values stored on `MachineComponentLink`/`MachinePieceLink`. Visible only from the machine detail page
+4. **Category editor** — UI for defining/editing custom fields in a ModelType skeleton
+
+## Backend Changes
+
+### Minor — format already consistent
+
+After review, `MachineStructureController` already serializes custom fields in the same format as API Platform:
+
+```json
+// CustomFieldValue (from normalizeCustomFieldValues)
+{
+  "id": "cfv-123",
+  "value": "USOCOME",
+  "customField": {
+    "id": "cf-456",
+    "name": "MARQUE",
+    "type": "text",
+    "required": false,

+  "orderIndex": 0,
+  "machineContextOnly": false
+}
+```
+
+The only backend task is adding `defaultValue` to the API Platform serialization groups on `CustomField.php` so that both API Platform and the custom controller return it.
+
+**Context fields on links** are returned as two separate arrays:
+- `contextCustomFields` — definitions filtered to `machineContextOnly=true`
+- `contextCustomFieldValues` — values stored on `MachineComponentLink`/`MachinePieceLink`
+
+This format stays as-is. The frontend unified module handles the merge.
+
+**Files:**
+- `src/Entity/CustomField.php` — add `#[Groups(['composant:read', 'piece:read', 'product:read', 'machine:read'])]` to `defaultValue`
+
+### Legacy `{key, value}` format in DB
+
+`SkeletonStructureService::normalizeCustomFieldData()` accepts two formats:
+- Legacy: `{key: "name", value: {type, required, options?, defaultValue?}}`
+- Standard: `{name, type, required, options?, defaultValue?}`
+
+**Pre-migration check required:** verify if any `ModelType` rows still have the legacy format in their structure data. If yes, write a one-time DB migration to normalize them before removing the frontend parsing code in Step 5. If no legacy data exists, the parsing code can be safely removed.
+
+## Frontend Changes
+
+### New Unified Module (2 files, ~400 lines total)
+
+**`shared/utils/customFields.ts`** (~180 lines) — Pure logic, zero Vue dependency
+
+Types:
+- `CustomFieldDefinition` — `{ id, name, type, required, options, defaultValue, orderIndex, machineContextOnly }`
+- `CustomFieldValue` — `{ id, value, customField: CustomFieldDefinition }`
+- `CustomFieldInput` — `{ ...CustomFieldDefinition, value, customFieldId, customFieldValueId }` (the merged type used by forms)
+
+Functions:
+- `mergeDefinitionsWithValues(definitions, values)` → `CustomFieldInput[]` — the ONE merge function replacing the 3 current ones. Matches by `customField.id` then by `name`. When no value exists for a definition, uses `defaultValue` as initial value.
+- `filterByContext(fields, context: 'standalone' | 'machine')` — filters on `machineContextOnly`
+- `sortByOrder(fields)` — sorts by `orderIndex`
+- `formatValueForSave(field)` / `shouldPersist(field)` — persistence helpers
+- `formatValueForDisplay(field)` — display helper (e.g. boolean → `Oui/Non`), replaces `formatCustomFieldValue` from `customFieldUtils.ts`
+- `fieldKey(field, index)` — stable key for v-for, replaces `fieldKey` from `customFieldFormUtils.ts`
+
+**`composables/useCustomFieldInputs.ts`** (~220 lines) — Reactive, wraps pure helpers
+
+```ts
+function useCustomFieldInputs(options: {
+  definitions: MaybeRef<CustomFieldDefinition[]>
+  values: MaybeRef<CustomFieldValue[]>
+  entityType: 'machine' | 'composant' | 'piece' | 'product' | 'machineComponentLink' | 'machinePieceLink'
+  entityId: MaybeRef<string | null>
+  context?: 'standalone' | 'machine'  // defaults to 'standalone'
+}): {
+  fields: ComputedRef<CustomFieldInput[]>
+  update: (field: CustomFieldInput) => Promise<void>
+  saveAll: () => Promise<string[]>  // returns failed field names
+  requiredFilled: ComputedRef<boolean>
+}
+```
+
+**Usage for context 3 (machine context fields on links):**
+```ts
+// For each MachineComponentLink, instantiate with:
+const contextFields = useCustomFieldInputs({
+  definitions: link.contextCustomFields,     // from MachineStructureController
+  values: link.contextCustomFieldValues,      // from MachineStructureController
+  entityType: 'machineComponentLink',
+  entityId: link.id,
+  context: 'machine',
+})
+```
+
+### Files Deleted After Migration
+
+| File | Lines | Replaced by |
+|------|-------|-------------|
+| `shared/utils/entityCustomFieldLogic.ts` | 335 | `shared/utils/customFields.ts` |
+| `shared/utils/customFieldUtils.ts` | 440 | `shared/utils/customFields.ts` |
+| `shared/utils/customFieldFormUtils.ts` | 404 | `shared/utils/customFields.ts` + `composables/useCustomFieldInputs.ts` |
+| `composables/useEntityCustomFields.ts` | 181 | `composables/useCustomFieldInputs.ts` |
+
+Additionally refactored (not deleted):
+- `composables/useMachineDetailCustomFields.ts` — custom fields code extracted, uses new module (keeps non-CF logic: constructeurs, products, transforms)
+- `shared/model/componentStructure.ts` — custom fields code removed (kept: structure/skeleton logic)
+- `shared/model/componentStructureSanitize.ts` — custom fields sanitize code removed
+- `shared/model/componentStructureHydrate.ts` — custom fields hydrate code removed
+
+### All consuming files to migrate
+
+**Composables:**
+- `composables/useComponentEdit.ts` — use `useCustomFieldInputs`
+- `composables/useComponentCreate.ts` — use `useCustomFieldInputs`
+- `composables/usePieceEdit.ts` — use `useCustomFieldInputs`
+- `composables/useMachineDetailCustomFields.ts` — use `useCustomFieldInputs` for all 3 machine sub-cases
+
+**Pages:**
+- `pages/component/[id]/index.vue` — already uses composable, minimal changes
+- `pages/component/[id]/edit.vue` — already uses composable, minimal changes
+- `pages/component/create.vue` — already uses composable, minimal changes
+- `pages/pieces/create.vue` — imports from `customFieldFormUtils`, migrate to new types
+- `pages/pieces/[id]/edit.vue` — already uses composable, minimal changes
+- `pages/product/create.vue` — imports from `customFieldFormUtils`, migrate to new types
+- `pages/product/[id]/edit.vue` — imports from `customFieldFormUtils`, migrate to new types
+- `pages/product/[id]/index.vue` — imports from `customFieldFormUtils`, migrate to new types
+
+**Shared components:**
+- `components/common/CustomFieldDisplay.vue` — imports 7 functions from `entityCustomFieldLogic`, rewrite with unified `CustomFieldInput` type
+- `components/common/CustomFieldInputGrid.vue` — imports `fieldKey` + `CustomFieldInput` from `customFieldFormUtils`, update imports
+- `components/ComponentItem.vue` — imports from `entityCustomFieldLogic` + `useEntityCustomFields`, migrate
+- `components/PieceItem.vue` — imports from `entityCustomFieldLogic` + `useEntityCustomFields`, migrate
+- `components/machine/MachineCustomFieldsCard.vue` — imports `formatCustomFieldValue` from `customFieldUtils`, use `formatValueForDisplay`
+- `components/machine/MachineInfoCard.vue` — imports `formatCustomFieldValue` from `customFieldUtils`, use `formatValueForDisplay`
+- `components/model-types/ModelTypeForm.vue` — use `shared/utils/customFields.ts` types
+
+**Tests:**
+- `tests/shared/customFieldFormUtils.test.ts` — rewrite for new module or delete
+
+## Migration Strategy — Progressive (6 steps)
+
+### Step 1: Backend minor fix + DB check
+- Add `defaultValue` to serialization groups in `CustomField.php`
+- Check DB for legacy `{key, value}` format in `model_types.structure` — write migration if needed
+- **Verify:** call `/api/composants/{id}`, confirm `defaultValue` appears in `customField` objects
+
+### Step 2: Create new module
+- Write `shared/utils/customFields.ts` and `composables/useCustomFieldInputs.ts`
+- Port existing test to new module
+- **Verify:** import in a test page, confirm merge/filter/sort/defaultValue work with real data
+
+### Step 3: Migrate standalone pages (composant/piece/product)
+- Refactor composables: `useComponentEdit.ts`, `useComponentCreate.ts`, `usePieceEdit.ts`
+- Refactor pages: `pieces/create.vue`, `product/create.vue`, `product/[id]/edit.vue`, `product/[id]/index.vue`
+- Refactor shared components: `CustomFieldInputGrid.vue`, `CustomFieldDisplay.vue`
+- **Verify per page:** open entity, check fields display with values (including defaultValue on new entities), modify a value, confirm save works
+
+### Step 4: Migrate machine page + hierarchy components
+- Refactor `useMachineDetailCustomFields.ts` — use `useCustomFieldInputs` for:
+  - Machine direct fields (definitions from `machine.customFields`, values from `machine.customFieldValues`)
+  - Standalone component/piece fields (definitions from `type.customFields`, values from entity's `customFieldValues`, filtered `machineContextOnly=false`)
+  - Machine context fields (definitions from `link.contextCustomFields`, values from `link.contextCustomFieldValues`)
+- Refactor `ComponentItem.vue`, `PieceItem.vue` — use `useCustomFieldInputs` instead of `useEntityCustomFields`
+- Refactor `MachineCustomFieldsCard.vue`, `MachineInfoCard.vue` — use `formatValueForDisplay`
+- **Verify:** open a machine with components that have both normal AND machine-context custom fields, check both display and save correctly
+
+### Step 5: Migrate category editor
+- Check DB for legacy `{key, value}` format — run migration if needed
+- Clean `componentStructure.ts`, `componentStructureSanitize.ts`, `componentStructureHydrate.ts` — remove custom fields code, use unified types from `customFields.ts`
+- Refactor `ModelTypeForm.vue`
+- **Verify:** edit a component category, modify skeleton custom fields, save, check linked components see changes
+
+### Step 6: Cleanup
+- Delete the 4 old files
+- Delete or rewrite `tests/shared/customFieldFormUtils.test.ts`
+- `npm run lint:fix` + `npx nuxi typecheck` = 0 errors
+- Final smoke test of all 4 contexts
+
+## Result
+
+- **~2900 lines → ~400 lines** + simplified consumers
+- **9 custom fields files → 2**
+- **3 parallel systems → 1**
+- **1 unified data format** understood by all pages
+- **`defaultValue` properly handled** across all contexts
+- **Legacy format eliminated** from DB and code
