+# 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`
+
+---
+
+## File Map
+
+### Create
+- `migrations/VersionXXXX_MachineContextCustomFields.php` — migration
+- `tests/Api/Entity/MachineContextCustomFieldTest.php` — test class
+
+### Modify
+- `src/Entity/CustomField.php` — add `machineContextOnly` property
+- `src/Entity/CustomFieldValue.php` — add `machineComponentLink` and `machinePieceLink` FKs
+- `src/Entity/MachineComponentLink.php` — add `contextFieldValues` collection
+- `src/Entity/MachinePieceLink.php` — add `contextFieldValues` collection
+- `src/Controller/MachineStructureController.php` — normalize context fields + clone
+- `src/Controller/CustomFieldValueController.php` — link-based upsert
+- `tests/AbstractApiTestCase.php` — extend factories
+
+---
+
+## Task 1: Migration + Entity `CustomField` — `machineContextOnly`
+
+**Files:**
+- Modify: `src/Entity/CustomField.php` (add property after line 56)
+
+- [ ] **Step 1: Add `machineContextOnly` property to `CustomField` entity**
+
+In `src/Entity/CustomField.php`, add after the `$required` property (line 56):
+
+```php
+#[ORM\Column(type: Types::BOOLEAN, options: ['default' => false], name: 'machinecontextonly')]
+#[Groups(['composant:read', 'piece:read', 'product:read', 'machine:read'])]
+private bool $machineContextOnly = false;
+```
+
+Add getter/setter before the closing `}`:

+```php
+public function isMachineContextOnly(): bool
+{
+    return $this->machineContextOnly;
+}
+
+public function setMachineContextOnly(bool $machineContextOnly): static
+{
+    $this->machineContextOnly = $machineContextOnly;
+
+    return $this;
+}
+```
+
+- [ ] **Step 2: Generate and adjust migration**
+
+```bash
+docker exec -u www-data php-inventory-apache php bin/console doctrine:migrations:diff
+```
+
+Edit the generated migration to use idempotent SQL:
+
+```sql
+ALTER TABLE custom_fields ADD COLUMN IF NOT EXISTS machinecontextonly BOOLEAN DEFAULT false NOT NULL;
+```
+
+- [ ] **Step 3: Run migration**
+
+```bash
+docker exec -u www-data php-inventory-apache php bin/console doctrine:migrations:migrate --no-interaction
+```
+
+- [ ] **Step 4: Run linter**
+
+```bash
+make php-cs-fixer-allow-risky
+```
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/Entity/CustomField.php migrations/

+
+## Task 2: Entity `CustomFieldValue` — link FKs + inverse collections
+
+**Files:**
+- Modify: `src/Entity/CustomFieldValue.php` (add after line 67 — `$product` property)
+- Modify: `src/Entity/MachineComponentLink.php` (add after line 72 — `$productLinks`)
+- Modify: `src/Entity/MachinePieceLink.php` (add after line 61 — `$productLinks`)
+
+- [ ] **Step 1: Add FKs to `CustomFieldValue`**
+
+In `src/Entity/CustomFieldValue.php`, add after the `$product` property (line 67):
+
+```php
+#[ORM\ManyToOne(targetEntity: MachineComponentLink::class, inversedBy: 'contextFieldValues')]
+#[ORM\JoinColumn(name: 'machinecomponentlinkid', referencedColumnName: 'id', nullable: true, onDelete: 'CASCADE')]

+
+Add getters/setters before the closing `}`:
+
+```php

+public function setMachinePieceLink(?MachinePieceLink $machinePieceLink): static
+{
+    $this->machinePieceLink = $machinePieceLink;
+
+    return $this;
+}
+```
+
+- [ ] **Step 2: Add `contextFieldValues` collection to `MachineComponentLink`**
+
+In `src/Entity/MachineComponentLink.php`, add after the `$productLinks` collection (line 72):
+
+```php
+/**
+ * @var Collection<int, CustomFieldValue>
+ */
+#[ORM\OneToMany(mappedBy: 'machineComponentLink', targetEntity: CustomFieldValue::class, cascade: ['persist', 'remove'], orphanRemoval: true)]

+
+```php
+/**
+ * @var Collection<int, CustomFieldValue>

+```
+
+In the constructor (line 86), add:

+public function getContextFieldValues(): Collection
+{
+    return $this->contextFieldValues;
+}
+```
+
+- [ ] **Step 4: Generate and adjust migration**
+
+```bash
+docker exec -u www-data php-inventory-apache php bin/console doctrine:migrations:diff

+
+Edit migration to use idempotent SQL:
+```sql

+
+---
+
+## Task 3: Test factories — extend helpers
+
+**Files:**
+- Modify: `tests/AbstractApiTestCase.php:399-461`
+
+- [ ] **Step 1: Update `createCustomField()` factory**
+
+In `tests/AbstractApiTestCase.php`, add `bool $machineContextOnly = false` parameter at the end of `createCustomField` (line 399), and add `$cf->setMachineContextOnly($machineContextOnly);` after `$cf->setOrderIndex($orderIndex);` (line 411).
+
+- [ ] **Step 2: Update `createCustomFieldValue()` factory**
+
+Add two new nullable parameters at the end of `createCustomFieldValue` (line 432):
+
+```php
+?MachineComponentLink $machineComponentLink = null,
+?MachinePieceLink $machinePieceLink = null,
+```
+
+Add the corresponding setter calls **after the closing `}` of the `if (null !== $product)` block** (after line 454, NOT inside it):
+
+```php
+if (null !== $machineComponentLink) {
+    $cfv->setMachineComponentLink($machineComponentLink);
+}
+if (null !== $machinePieceLink) {
+    $cfv->setMachinePieceLink($machinePieceLink);
+}
+```
+
+- [ ] **Step 3: Run linter**
+
+```bash
+make php-cs-fixer-allow-risky
+```
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add tests/AbstractApiTestCase.php
+git commit -m "test(custom-fields) : extend factories for machineContextOnly and link params"
+```
+
+---
+
+## Task 4: `MachineStructureController` — normalize context fields
+
+**Files:**
+- 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()) {
+            continue;
+        }
+        $items[] = [
+            'id'                 => $cf->getId(),
+            'name'               => $cf->getName(),
+            'type'               => $cf->getType(),
+            'required'           => $cf->isRequired(),
+            'options'            => $cf->getOptions(),
+            'defaultValue'       => $cf->getDefaultValue(),
+            'orderIndex'         => $cf->getOrderIndex(),
+            'machineContextOnly' => true,
+        ];
+    }
+
+    usort($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:
+
+```php
+private function normalizeComponentLinks(array $links): array
+{
+    return array_map(function (MachineComponentLink $link): array {
+        $composant  = $link->getComposant();
+        $parentLink = $link->getParentLink();
+        $type       = $composant->getTypeComposant();
+
+        return [
+            'id'                       => $link->getId(),
+            'linkId'                   => $link->getId(),
+            'machineId'                => $link->getMachine()->getId(),
+            'composantId'              => $composant->getId(),
+            'composant'                => $this->normalizeComposant($composant),
+            'parentLinkId'             => $parentLink?->getId(),
+            'parentComponentLinkId'    => $parentLink?->getId(),

+- [ ] **Step 4: Update `normalizePieceLinks` to include context fields**

+```php
+private function normalizePieceLinks(array $links): array
+{
+    return array_map(function (MachinePieceLink $link): array {
+        $piece      = $link->getPiece();

+            'contextCustomFieldValues' => $this->normalizeCustomFieldValues($link->getContextFieldValues()),
+        ];
+    }, $links);
+}
+```
+
+- [ ] **Step 5: Run linter**
+
+```bash
+make php-cs-fixer-allow-risky
+```
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/Controller/MachineStructureController.php
+git commit -m "feat(custom-fields) : expose context custom fields in machine structure response"
+```
+
+---
+
+## 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
+git commit -m "feat(custom-fields) : support link-based upsert in CustomFieldValueController"
+```
+

+
+## 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,
+    array $pieceLinkMap,
+): void {
+    foreach ($componentLinkMap as $oldLinkId => $newLink) {
+        $oldLink = $this->machineComponentLinkRepository->find($oldLinkId);
+        if (!$oldLink) {
+            continue;
+        }
+        foreach ($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());
+            $newValue->setValue($cfv->getValue());
+            $newValue->setMachinePieceLink($newLink);
+            $newValue->setPiece($newLink->getPiece());
+            $this->entityManager->persist($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:
+
+```php
+$this->cloneContextFieldValues($componentLinkMap, $pieceLinkMap);
+```
+
+- [ ] **Step 3: Run linter**
+
+```bash
+make php-cs-fixer-allow-risky

+```bash

+# 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`

+
+- [ ] **Step 1: Add toggle in `PieceModelStructureEditor.vue`**
+
+After the "Obligatoire" checkbox block (line 125, after `</div>` closing the required checkbox), add:

+```
+
+- [ ] **Step 2: Update `usePieceStructureEditorLogic.ts` — 3 functions**
+
+**a) `createEmptyField`** (line 283) — add `machineContextOnly: false` to the returned object:

+# 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
