+# 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`

+## 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;
+```

+# 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 .

+---
+
+## 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(() => {

+  } 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

+# 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
