+- `DocumentServeController` — `/api/documents/{id}/file|download` (GET) : servir/télécharger fichiers.

+- **Composants/Pièces/Produits** : définitions dans les entités `SkeletonPieceRequirement`, `SkeletonProductRequirement`, `SkeletonSubcomponentRequirement` du ModelType (anciennement JSON `structure`, normalisé en tables relationnelles). Les custom fields de ces entités sont définis dans `customFields` JSON sur chaque Skeleton*Requirement.
 - **Machines** : définitions = entités `CustomField` liées directement via `machineId` FK (pas de ModelType)
 - Les deux partagent la même entité `CustomFieldValue` pour stocker les valeurs
 
+### Normalisation JSON → Tables (architecture slots)
+Les anciennes colonnes JSON `structure` et `productIds` des Composants ont été remplacées par des tables relationnelles :

+
+Serveur MCP (Model Context Protocol) pour l'application Inventory. Permet aux assistants IA (Claude, ChatGPT, Codex) de consulter et gérer l'inventaire industriel.
+
+## Prérequis
+
+- Un profil actif avec rôle suffisant (ROLE_VIEWER pour lecture, ROLE_GESTIONNAIRE pour écriture)
+- Accès au tunnel pour les clients distants (Claude Desktop, ChatGPT Desktop)
+- Docker Compose démarré (`make start`)
+

+### Creer un composant complet
+
+```
+1. list_model_types(category: "composant")      -> choisir le type
+2. get_model_type(modelTypeId: "...")            -> voir le skeleton
+3. create_composant(name, reference, modelTypeId) -> cree + slots auto
+4. search_inventory(query: "Roulement", types: "piece") -> trouver pieces
+5. update_slots(slots: [{slotId, selectedPieceId}])     -> remplir
+6. upsert_custom_field_values(entityType: "composant", entityId, fields: [...])
+```
+
+### Creer une machine complete (bottom-up)
+
+```
+1. Creer les produits necessaires
+2. Creer les pieces (avec produits dans les slots)
+3. Creer les composants (avec pieces dans les slots)
+4. list_sites -> choisir le site
+5. create_machine(name, siteId)
+6. add_machine_links(machineId, links: [{type: "composant", entityId, quantity}])

+# Piece Quantity Implementation Plan
+
+> **For agentic workers:** REQUIRED: Use superpowers:subagent-driven-development (if subagents available) or superpowers:executing-plans to implement this plan. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add a quantity field to pieces — on `MachinePieceLink` for machine-direct pieces, and in `Composant.structure.pieces[]` JSON for composant pieces.
+
+**Architecture:** Quantity lives on the relationship, not the catalogue entity. For machine-direct pieces, a new `quantity` integer column on `MachinePieceLink` (default 1). For composant pieces, a `quantity` key in the existing `structure.pieces[]` JSON (default 1). Display: "×N" after piece name, hidden when N=1.
+
+**Tech Stack:** Symfony 8 / API Platform, Doctrine ORM, PostgreSQL, Nuxt 4, Vue 3 Composition API, TypeScript, DaisyUI 5
+
+**Spec:** `docs/superpowers/specs/2026-03-12-piece-quantity-design.md`
+
+---
+
+## Chunk 1: Backend
+
+### Task 1: Entity + Migration
+
+**Files:**
+- Modify: `src/Entity/MachinePieceLink.php`
+- Existing: `migrations/Version20260309150000.php` (already written, untracked)
+
+- [ ] **Step 1: Add quantity field to MachinePieceLink entity**
+
+In `src/Entity/MachinePieceLink.php`, add after the `prixOverride` field (line 69):
+
+```php
+#[ORM\Column(type: Types::INTEGER, options: ['default' => 1])]
+#[Assert\GreaterThanOrEqual(1)]
+private int $quantity = 1;
+```
+
+Add the import at the top if not present:
+```php
+use Symfony\Component\Validator\Constraints as Assert;
+```
+
+Add getter/setter after existing methods (before closing brace):
+
+```php
+public function getQuantity(): int
+{
+    return $this->quantity;
+}
+
+public function setQuantity(int $quantity): static
+{
+    $this->quantity = $quantity;
+
+    return $this;
+}
+```
+
+- [ ] **Step 2: Stage the migration file**
+
+The migration `migrations/Version20260309150000.php` already exists (untracked). Verify its content matches:
+
+```php
+public function up(Schema $schema): void
+{
+    $this->addSql('ALTER TABLE machine_piece_links ADD COLUMN IF NOT EXISTS quantity INTEGER NOT NULL DEFAULT 1');
+}
+```
+
+- [ ] **Step 3: Run php-cs-fixer**
+
+Run: `make php-cs-fixer-allow-risky`
+
+- [ ] **Step 4: Run tests to verify nothing is broken**
+
+Run: `make test`
+Expected: All 167 tests pass (OK, with possible deprecation warnings)
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/Entity/MachinePieceLink.php migrations/Version20260309150000.php
+git commit -m "feat(piece) : add quantity field to MachinePieceLink entity + migration"
+```
+
+---
+
+### Task 2: MachineStructureController — Normalization + PATCH + Clone
+
+**Files:**
+- Modify: `src/Controller/MachineStructureController.php`
+
+- [ ] **Step 1: Add quantity to `normalizePieceLinks()`**
+
+In `src/Controller/MachineStructureController.php`, method `normalizePieceLinks()` (line ~623-641).
+
+Add `'quantity'` to the returned array, after `'overrides'`:
+
+```php
+'quantity' => $this->resolvePieceQuantity($link),
+```
+
+Add a new private method after `normalizePieceLinks()`:
+
+```php
+private function resolvePieceQuantity(MachinePieceLink $link): int
+{
+    $parentLink = $link->getParentLink();
+
+    if (!$parentLink) {
+        return $link->getQuantity();
+    }
+
+    $composant = $parentLink->getComposant();
+    $structure = $composant->getStructure();
+
+    if (!is_array($structure) || !isset($structure['pieces']) || !is_array($structure['pieces'])) {
+        return 1;
+    }
+
+    $piece = $link->getPiece();
+    $typePiece = $piece->getTypePiece();
+    $typePieceId = $typePiece?->getId();
+
+    foreach ($structure['pieces'] as $pieceDef) {
+        if (!is_array($pieceDef)) {
+            continue;
+        }
+        if (isset($pieceDef['typePieceId']) && $pieceDef['typePieceId'] === $typePieceId) {
+            return (int) ($pieceDef['quantity'] ?? 1);
+        }
+    }
+
+    return 1;
+}
+```
+
+**Note:** Matching is done by `typePieceId`. If a composant has two pieces of the same type, they will get the same quantity (first match). This is an acceptable limitation for now — duplicates of the same piece type in a composant are rare.
+
+- [ ] **Step 2: Apply quantity in `applyPieceLinks()`**
+
+In method `applyPieceLinks()` (line ~366-422), add quantity application after `$this->applyOverrides($link, $entry['overrides'] ?? null);` (line ~396):
+
+```php
+if (!isset($entry['parentComponentLinkId']) && !isset($entry['parentLinkId'])) {
+    $quantity = isset($entry['quantity']) ? (int) $entry['quantity'] : $link->getQuantity();
+    $link->setQuantity(max(1, $quantity));
+}
+```
+
+**Key behavior:**
+- Only applies to direct machine pieces (no parent component link)
+- If `quantity` not in payload: preserves existing value
+- If `quantity` in payload: sets it, with floor of 1
+- For composant-child pieces: quantity is ignored (comes from composant structure)
+
+- [ ] **Step 3: Copy quantity in `clonePieceLinks()`**
+
+In method `clonePieceLinks()` (line ~233-256), add after `$newLink->setPrixOverride($link->getPrixOverride());` (line ~244):
+
+```php
+$newLink->setQuantity($link->getQuantity());
+```
+
+- [ ] **Step 4: Run php-cs-fixer**
+
+Run: `make php-cs-fixer-allow-risky`
+
+- [ ] **Step 5: Run tests**
+
+Run: `make test`
+Expected: All tests pass
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/Controller/MachineStructureController.php
+git commit -m "feat(piece) : add quantity to structure normalization, PATCH and clone"
+```
+
+---
+
+### Task 3: Backend Tests
+
+**Files:**
+- Modify: `tests/Api/Entity/MachinePieceLinkTest.php`
+- Modify: `tests/AbstractApiTestCase.php` (factory method)
+
+- [ ] **Step 1: Update factory method to support quantity**
+
+In `tests/AbstractApiTestCase.php`, update `createMachinePieceLink()` to accept an optional quantity parameter:
+
+```php
+protected function createMachinePieceLink(Machine $machine, Piece $piece, ?MachineComponentLink $parentLink = null, int $quantity = 1): MachinePieceLink
+{
+    $link = new MachinePieceLink();
+    $link->setMachine($machine);
+    $link->setPiece($piece);
+    $link->setQuantity($quantity);
+    if (null !== $parentLink) {
+        $link->setParentLink($parentLink);
+    }
+
+    $em = $this->getEntityManager();
+    $em->persist($link);
+    $em->flush();
+
+    return $link;
+}
+```
+
+- [ ] **Step 2: Add test for POST with explicit quantity**
+
+In `tests/Api/Entity/MachinePieceLinkTest.php`, add. Follow the existing test pattern — use `$this->assertJsonContains()` and include the `headers` key with `Content-Type`:
+
+```php
+public function testPostWithQuantity(): void
+{
+    $client = $this->createGestionnaireClient();
+    $machine = $this->createMachine();
+    $piece = $this->createPiece();
+
+    $client->request('POST', '/api/machine_piece_links', [
+        'headers' => ['Content-Type' => 'application/ld+json'],
+        'json' => [
+            'machine' => '/api/machines/' . $machine->getId(),
+            'piece' => '/api/pieces/' . $piece->getId(),
+            'quantity' => 5,
+        ],
+    ]);
+
+    $this->assertResponseStatusCodeSame(201);
+    $this->assertJsonContains(['quantity' => 5]);
+}
+```
+
+- [ ] **Step 3: Add test for POST without quantity (default = 1)**
+
+```php
+public function testPostDefaultQuantity(): void
+{
+    $client = $this->createGestionnaireClient();
+    $machine = $this->createMachine();
+    $piece = $this->createPiece();
+
+    $client->request('POST', '/api/machine_piece_links', [
+        'headers' => ['Content-Type' => 'application/ld+json'],
+        'json' => [
+            'machine' => '/api/machines/' . $machine->getId(),
+            'piece' => '/api/pieces/' . $piece->getId(),
+        ],
+    ]);
+
+    $this->assertResponseStatusCodeSame(201);
+    $this->assertJsonContains(['quantity' => 1]);
+}
+```
+
+- [ ] **Step 4: Run tests**
+
+Run: `make test`
+Expected: All tests pass including new ones
+
+- [ ] **Step 5: Run php-cs-fixer**
+
+Run: `make php-cs-fixer-allow-risky`
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add tests/Api/Entity/MachinePieceLinkTest.php tests/AbstractApiTestCase.php
+git commit -m "test(piece) : add quantity tests for MachinePieceLink"
+```

+## Chunk 2: Frontend
+
+### Task 4: TypeScript Types + Sanitization + Hydration Functions
+
+**Files:**
+- Modify: `Inventory_frontend/app/shared/types/inventory.ts`
+- Modify: `Inventory_frontend/app/shared/model/componentStructure.ts`
+- Modify: `Inventory_frontend/app/shared/model/componentStructureSanitize.ts`
+- Modify: `Inventory_frontend/app/shared/model/componentStructureHydrate.ts`
+- Modify: `Inventory_frontend/app/shared/utils/structureAssignmentHelpers.ts`
+
+- [ ] **Step 1: Add `quantity` to `ComponentModelPiece` type**
+
+In `Inventory_frontend/app/shared/types/inventory.ts`, add `quantity` to the `ComponentModelPiece` interface (after `role`, line ~23):
+
+```typescript
+quantity?: number
+```
+
+- [ ] **Step 2: Add `quantity` to `validatePiece()` in same file**
+
+In `Inventory_frontend/app/shared/types/inventory.ts`, in `validatePiece()` (line ~144-172):
+
+After `const role = ensureString(value.role)` (line ~161), add:
+
+```typescript
+const quantity = typeof value.quantity === 'number' && value.quantity >= 1 ? value.quantity : undefined
+```
+
+And in the return object, add after the `role` spread:
+
+```typescript
+...(quantity ? { quantity } : {}),
+```
+
+- [ ] **Step 3: Update `sanitizePieces()` to preserve quantity**
+
+In `Inventory_frontend/app/shared/model/componentStructureSanitize.ts`, in `sanitizePieces()` (~line 130-188).
+
+After the existing field extractions, add:
+
+```typescript
+const quantity = typeof piece?.quantity === 'number' && piece.quantity >= 1 ? piece.quantity : undefined
+```
+
+In the result object construction, add alongside existing fields (follow the `if (field) { result.field = field }` pattern used in this function):
+
+```typescript
+if (quantity !== undefined) {
+  result.quantity = quantity
+}
+```
+
+- [ ] **Step 4: Update `normalizeStructureForSave()` to include quantity**
+
+In `Inventory_frontend/app/shared/model/componentStructure.ts`, in `normalizeStructureForSave()` (~lines 164-179), add in the piece payload mapping after the `reference` check:
+
+```typescript
+if ((piece as any).quantity !== undefined && (piece as any).quantity >= 1) {
+  payload.quantity = (piece as any).quantity
+}
+```
+
+**Note:** Always send quantity when defined (including 1), so the backend always has an explicit value.
+
+- [ ] **Step 5: Update `hydratePieces()` and `mapComponentPieces()` to preserve quantity**
+
+In `Inventory_frontend/app/shared/model/componentStructureHydrate.ts`:
+
+In `hydratePieces()` (line ~95-107), add to the mapped object:
+
+```typescript
+...(piece?.quantity !== undefined && piece.quantity >= 1 ? { quantity: piece.quantity } : {}),
+```
+
+In `mapComponentPieces()` (line ~168-179), add to the mapped object:
+
+```typescript
+...(piece?.quantity !== undefined && piece.quantity >= 1 ? { quantity: piece.quantity } : {}),
+```
+
+- [ ] **Step 6: Update `sanitizePieceDefinition()` to preserve quantity**
+
+In `Inventory_frontend/app/shared/utils/structureAssignmentHelpers.ts`, in `sanitizePieceDefinition()` (~lines 172-180), add to the `stripNullish()` object:
+
+```typescript
+quantity: typeof (definition as any).quantity === 'number' ? (definition as any).quantity : null,
+```
+
+- [ ] **Step 7: Run lint + typecheck**
+
+```bash
+cd Inventory_frontend && npm run lint:fix && npx nuxi typecheck
+```
+Expected: 0 errors
+
+- [ ] **Step 8: Commit**
+
+```bash
+cd Inventory_frontend
+git add app/shared/types/inventory.ts app/shared/model/componentStructure.ts app/shared/model/componentStructureSanitize.ts app/shared/model/componentStructureHydrate.ts app/shared/utils/structureAssignmentHelpers.ts
+git commit -m "feat(piece) : add quantity field to piece types, sanitization and hydration"
+```
+

+
+### Task 5: Composant Structure Editor — Quantity Input
+
+**Files:**
+- Modify: `Inventory_frontend/app/components/StructureNodeEditor.vue` (piece section, lines ~229-299)
+- Modify: `Inventory_frontend/app/composables/useStructureNodeCrud.ts` (`addPiece()`, lines ~110-118)
+
+**Context:** `StructureNodeEditor.vue` renders the composant structure editor. The piece section (lines ~236-293) currently shows only a `select` for `typePieceId` and a delete button. The `addPiece()` function in `useStructureNodeCrud.ts` creates new piece entries with default fields.
+
+- [ ] **Step 1: Add default quantity to `addPiece()`**
+
+In `Inventory_frontend/app/composables/useStructureNodeCrud.ts`, in `addPiece()` (line ~110-118), add `quantity: 1` to the pushed object:
+
+```typescript
+const addPiece = () => {
+  ensureArray('pieces')
+  props.node.pieces!.push({
+    typePieceId: '',
+    typePieceLabel: '',
+    reference: '',
+    familyCode: '',
+    role: '',
+    quantity: 1,
+  })
+}
+```
+
+- [ ] **Step 2: Add quantity input in `StructureNodeEditor.vue`**
+
+In `Inventory_frontend/app/components/StructureNodeEditor.vue`, in the piece item rendering section (inside the `v-for` loop for pieces, line ~256-292), add a quantity input next to the existing piece type `select`. Place it after the select and before the delete button:
+
+```vue
+<input
+  v-model.number="piece.quantity"
+  type="number"
+  :min="1"
+  step="1"
+  placeholder="Qté"
+  class="input input-bordered input-sm md:input-md w-20"
+  @input="piece.quantity = Math.max(1, piece.quantity || 1)"
+/>
+```
+
+- [ ] **Step 3: Run lint + typecheck**
+
+```bash
+cd Inventory_frontend && npm run lint:fix && npx nuxi typecheck
+```
+Expected: 0 errors
+
+- [ ] **Step 4: Commit**
+
+```bash
+cd Inventory_frontend
+git add app/components/StructureNodeEditor.vue app/composables/useStructureNodeCrud.ts
+git commit -m "feat(piece) : add quantity input to composant structure editor"
+```
+
+---
+
+### Task 6: Machine Detail Page — Display Quantity
+
+**Files:**
+- Modify: `Inventory_frontend/app/components/PieceItem.vue`
+
+**Context:** `PieceItem.vue` renders each piece in the machine structure view. The piece name is displayed at line ~26 in an `<h3>` tag. Quantity should appear as "×N" after the name, in secondary text. For direct pieces (no parent component), it should be editable. For composant pieces, read-only.
+
+- [ ] **Step 1: Add quantity display to PieceItem**
+
+In `Inventory_frontend/app/components/PieceItem.vue`, after the piece name in the `<h3>` tag (line ~26), add the quantity display:
+
+```vue
+<span
+  v-if="displayQuantity > 1"
+  class="text-sm font-normal text-base-content/60 ml-1"
+>
+  ×{{ displayQuantity }}
+</span>
+```
+
+Add to the component's setup:
+
+```typescript
+const displayQuantity = computed(() => {
+  return props.piece.quantity ?? 1
+})
+```
+
+- [ ] **Step 2: Add editable quantity for direct machine pieces**
+
+For pieces directly on a machine (no `parentComponentLinkId`), add an editable quantity input in the piece's edit section, following the pattern of existing override fields (nameOverride, referenceOverride, prixOverride). Place it alongside the overrides form:
+
+```vue
+<div v-if="!piece.parentComponentLinkId && isEditMode" class="form-control">
+  <label class="label">
+    <span class="label-text text-sm">Quantité</span>
+  </label>
+  <input
+    v-model.number="pieceData.quantity"
+    type="number"
+    min="1"
+    step="1"
+    class="input input-bordered input-sm md:input-md w-24"
+  />
+</div>
+```
+
+Add `quantity` to the `pieceData` reactive object (line ~270-275):
+
+```typescript
+quantity: props.piece.quantity ?? 1,
+```
+
+Ensure this value is included in the data emitted when saving (follow the same pattern as `nameOverride`, `referenceOverride`, `prixOverride` in the save/emit logic).
+
+- [ ] **Step 3: Run lint + typecheck**
+
+```bash
+cd Inventory_frontend && npm run lint:fix && npx nuxi typecheck
+```
+Expected: 0 errors
+
+- [ ] **Step 4: Commit**
+
+```bash
+cd Inventory_frontend
+git add app/components/PieceItem.vue
+git commit -m "feat(piece) : display and edit quantity on machine piece items"
+```
+
+---
+
+### Task 7: Submodule Update + Final Verification
+
+**Files:**
+- Update submodule pointer in main repo
+
+- [ ] **Step 1: Push frontend commits**
+
+```bash
+cd Inventory_frontend && git push
+```
+
+- [ ] **Step 2: Update submodule pointer in main repo**
+
+```bash
+cd /home/matthieu/dev_malio/Inventory
+git add Inventory_frontend
+git commit -m "chore(frontend) : update submodule — piece quantity feature"
+```
+
+- [ ] **Step 3: Run all backend tests**
+
+Run: `make test`
+Expected: All tests pass
+
+- [ ] **Step 4: Run migration on dev database**
+
+```bash
+docker exec -u www-data php-inventory-apache php bin/console doctrine:migrations:migrate --no-interaction
+```
+
+- [ ] **Step 5: Manual smoke test**
+
+1. Open a composant edit page → verify quantity input appears on each piece in structure
+2. Set quantity to 4, save → reload → verify quantity persisted
+3. Open a machine with that composant → verify "×4" appears next to piece name (read-only)
+4. Add a piece directly to a machine → verify quantity input appears in edit mode
+5. Set quantity to 3, save → verify "×3" appears
+6. Clone the machine → verify cloned pieces have same quantities

+# Piece Quantity — Design Spec
+
+## Context
+
+L'application gère des machines composées de composants et de pièces. Une même pièce (catalogue) peut apparaître dans plusieurs contextes avec des quantités différentes. La quantité doit être portée par la **relation**, pas par l'entité catalogue.
+
+## Scope
+
+- Quantité sur les **pièces directement liées à une machine** (`MachinePieceLink`)
+- Quantité sur les **pièces d'un composant** (JSON `structure.pieces` du `Composant`)
+- **Hors scope** : quantité sur `MachineComponentLink`, `MachineProductLink`, override de quantité composant au niveau machine, audit logging
+
+## Règles métier
+
+| Contexte | Stockage | Éditable depuis | Visible sur machine |
+|----------|----------|-----------------|---------------------|
+| Pièce directement sur machine | `MachinePieceLink.quantity` | Page machine | Oui, éditable |
+| Pièce d'un composant | `Composant.structure.pieces[].quantity` | Page composant (création + édition) | Oui, lecture seule |
+
+- Type : entier, valeur par défaut = 1, minimum = 1
+- Affichage : "×N" après le nom de la pièce, masqué si N = 1
+- Quantité = 0 n'est pas valide (utiliser la suppression du lien à la place)
+
+## Backend
+
+### 1. MachinePieceLink — Nouvelle colonne
+
+Ajout d'un champ `quantity` sur l'entité `MachinePieceLink` :
+
+```php
+#[ORM\Column(type: Types::INTEGER, options: ['default' => 1])]
+private int $quantity = 1;
+```
+
+Getter/setter standard. **Pas de `#[Groups]`** — cohérent avec les autres champs de l'entité qui n'en déclarent pas (l'entité n'a pas de `normalizationContext`).
+
+Validation : `#[Assert\GreaterThanOrEqual(1)]`
+
+### 2. Migration SQL
+
+```sql
+ALTER TABLE machine_piece_link ADD COLUMN IF NOT EXISTS quantity INTEGER NOT NULL DEFAULT 1;
+```
+
+Idempotente avec `IF NOT EXISTS`.
+
+### 3. Composant.structure JSON
+
+Le tableau `pieces` dans le JSON `structure` du Composant accepte une nouvelle clé `quantity`. Pas de migration DB nécessaire — c'est un champ JSON libre.
+
+Avant :
+```json
+{ "typePieceId": "...", "role": "Filtration" }
+```
+
+Après :
+```json
+{ "typePieceId": "...", "role": "Filtration", "quantity": 4 }
+```
+
+Les entrées existantes sans `quantity` sont traitées comme `quantity = 1` (défaut côté frontend et backend).
+
+### 4. MachineStructureController
+
+#### Normalisation (GET)
+
+`normalizePieceLinks()` : inclure `quantity` dans la réponse JSON :
+- **Pièce machine directe** (parentLink = null) : `quantity` depuis `MachinePieceLink.quantity`
+- **Pièce sous composant** : `quantity` depuis le `structure.pieces` du composant source. Résolution :
+  1. Naviguer `MachinePieceLink` → `parentLink` (MachineComponentLink) → `composant` → `structure['pieces']`
+  2. Matcher par index de position dans le tableau `pieces` (l'ordre des pièces dans la structure correspond à l'ordre de création des liens)
+  3. Fallback : `quantity = 1` si non trouvé
+
+#### PATCH structure
+
+Dans `applyPieceLinks()`, accepter `quantity` au même niveau que `pieceId` dans le payload :
+
+```json
+{
+  "pieceLinks": [
+    { "pieceId": "cl...", "quantity": 4, "overrides": { "nameOverride": "..." } }
+  ]
+}
+```
+
+- `quantity` est appliqué uniquement pour les pièces directement sur la machine (pas de `parentComponentLinkId`)
+- Si `parentComponentLinkId` est présent, `quantity` est **ignoré silencieusement** (la valeur vient du composant)
+
+#### Clone
+
+`clonePieceLinks()` doit copier `quantity` depuis le lien source :
+
+```php
+$newLink->setQuantity($link->getQuantity());
+```
+
+Sans cela, les machines clonées perdraient les quantités (reset à 1).
+
+### 5. Tests
+
+Ajouter dans `MachinePieceLinkTest.php` :
+- POST avec `quantity` explicite → vérifier la valeur
+- POST sans `quantity` → vérifier défaut = 1
+- PATCH `quantity` sur pièce directe → vérifier mise à jour
+- GET structure → vérifier `quantity` dans la réponse normalisée
+- Clone → vérifier que `quantity` est préservé
+
+## Frontend
+
+### 1. Types TypeScript
+
+Mise à jour de `ComponentModelPiece` dans `shared/types/inventory.ts` — ajout du champ `quantity` :
+
+```typescript
+quantity?: number  // défaut 1
+```
+
+### 2. Fonctions de sanitization/normalisation à mettre à jour
+
+Ces fonctions énumèrent explicitement les champs à conserver et doivent inclure `quantity` :
+
+- `normalizeStructureForSave()` dans `shared/model/componentStructure.ts` — inclure `quantity` dans le payload backend des pièces
+- `sanitizePieceDefinition()` dans `shared/utils/structureAssignmentHelpers.ts` — préserver `quantity`
+- `sanitizePieces()` dans `shared/model/componentStructureSanitize.ts` — préserver `quantity` dans la sortie
+- `hydratePieces()` / `mapComponentPieces()` — préserver `quantity` lors de l'hydratation
+
+### 3. Pages composant (création + édition)
+
+Dans l'éditeur de structure, chaque pièce du tableau `structure.pieces` affiche un champ input :

+
+- **Pièce directe** (parentLink = null) : affiche "×N" à côté du nom, quantité éditable (input entier)
+- **Pièce de composant** : affiche "×N" à côté du nom, lecture seule (pas d'input)
+- Si quantité = 1 : rien n'est affiché (pas de bruit visuel)
+- Style du label : texte secondaire (`text-base-content/60` ou classe équivalente)

+# ModelType Sync — Design Spec
+
+## Objectif
+
+Quand un ModelType (catégorie) est modifié (structure, custom fields), propager automatiquement les changements à tous les items liés (Composants, Pièces, Produits). L'utilisateur voit un preview de l'impact et confirme avant que la sync ne s'exécute.
+
+## Décisions
+
+| Décision | Choix |
+|----------|-------|
+| Scope sync | Composants + Pièces + Produits |
+| Sync destructive | Avec confirmation (modal frontend) |
+| Custom fields — ajout | Créer `CustomFieldValue` vides |
+| Custom fields — suppression | Supprimer avec confirmation |
+| Custom fields — renommage | Propagation auto (label dans la définition) |
+| Custom fields — changement de type | Clear les valeurs avec confirmation |
+| Architecture backend | Strategy pattern (1 strategy par entity type) |
+| Déclenchement | En deux temps : preview séparé du sync |
+| Preview timing | AVANT le save (pas de rollback nécessaire) |
+| Pièces — produits liés | Nouvelle table `PieceProductSlot` remplace la M2M `piece_products` |
+| `restrictedMode` frontend | Supprimé complètement |
+| Versioning | `version` INT sur Composant, Pièce, Produit (incrémenté à chaque sync) |
+| Machines | Aucun changement — elles lisent les slots des composants, la sync met à jour ces slots |
+| Matching slots | Par `typeXxxId` + `position` (pas de FK vers skeleton requirement) |
+| Matching custom fields | Par `orderIndex` (propriété stable sur `CustomField`) |
+| Atomicité PATCH + sync | Wrappé dans une transaction DB côté controller |
+| Idempotence sync | `execute()` est idempotent — un double appel est un no-op |
+| Audit | Les opérations de sync sont capturées par les subscribers `onFlush` existants |
+
+## Endpoints API
+
+### `POST /api/model_types/{id}/sync-preview`
+
+Calcule l'impact du diff entre le payload envoyé et l'état actuel des items liés. **Ne persiste rien.**
+
+**Sécurité :** `ROLE_GESTIONNAIRE`
+
+**Request body :**
+```json
+{
+  "structure": { ... }
+}
+```
+
+Le payload `structure` a le même format que celui envoyé au `PATCH /api/model_types/{id}`.
+
+**Response :**
+```json
+{
+  "modelTypeId": "cl...",
+  "category": "COMPONENT",
+  "itemCount": 12,
+  "additions": {
+    "pieceSlots": 12,
+    "productSlots": 0,
+    "subcomponentSlots": 24,
+    "customFieldValues": 36
+  },
+  "deletions": {
+    "pieceSlots": 0,
+    "productSlots": 12,
+    "subcomponentSlots": 0,
+    "customFieldValues": 0
+  },
+  "modifications": {
+    "customFieldTypeChanges": 12
+  }
+}
+```
+
+Si `additions`, `deletions` et `modifications` sont tous à 0, le frontend skip la modal et sauvegarde directement.
+
+**Erreurs :**
+- `404` — ModelType introuvable
+- `403` — droits insuffisants
+
+### `POST /api/model_types/{id}/sync`
+
+Exécute la propagation. Appelé **après** le `PATCH` du ModelType, dans la même requête frontend (PATCH + sync enchaînés).
+
+**Sécurité :** `ROLE_GESTIONNAIRE`
+
+**Request body :**
+```json
+{
+  "confirmDeletions": true,
+  "confirmTypeChanges": true
+}
+```
+
+Si des suppressions sont nécessaires mais `confirmDeletions` est `false`, le sync **skip les suppressions** (applique uniquement les ajouts). Idem pour `confirmTypeChanges` et les clear de valeurs. Cela permet un sync partiel (ajouts only) sans confirmation.
+
+**Response :** `200` avec résumé de l'exécution.
+
+**Erreurs :**
+- `404` — ModelType introuvable
+- `403` — droits insuffisants
+
+## Architecture Backend
+
+### Strategy Pattern
+
+```
+Service/
+├── ModelTypeSyncService.php          # Orchestrateur
+└── Sync/
+    ├── SyncStrategyInterface.php     # Interface
+    ├── ComposantSyncStrategy.php     # Slots pièce/produit/sous-composant + custom fields
+    ├── PieceSyncStrategy.php         # Slots produit + custom fields
+    └── ProductSyncStrategy.php       # Custom fields uniquement
+```
+
+### Interface
+
+```php
+interface SyncStrategyInterface
+{
+    public function supports(ModelType $modelType): bool;
+    public function preview(ModelType $modelType, array $newStructure): SyncPreviewResult;
+    public function execute(ModelType $modelType, SyncConfirmation $confirmation): SyncExecutionResult;
+}
+```
+
+**Note sur `execute()` :** Cette méthode est appelée **après** le PATCH du ModelType, donc les skeleton requirements sont déjà mis à jour en base. La strategy compare les skeleton requirements actuels (fraîchement mis à jour) avec les slots existants des items liés. Pas besoin de recevoir `$newStructure` — les relations ORM reflètent déjà le nouvel état.
+
+### Orchestrateur
+
+```php
+class ModelTypeSyncService
+{
+    /** @param iterable<SyncStrategyInterface> $strategies */
+    public function __construct(private iterable $strategies) {}
+
+    public function preview(ModelType $modelType, array $newStructure): SyncPreviewResult
+    {
+        foreach ($this->strategies as $strategy) {
+            if ($strategy->supports($modelType)) {
+                return $strategy->preview($modelType, $newStructure);
+            }
+        }
+        throw new \LogicException('No strategy found for category: ' . $modelType->getCategory()->value);
+    }
+
+    public function execute(ModelType $modelType, SyncConfirmation $confirmation): SyncExecutionResult
+    {
+        foreach ($this->strategies as $strategy) {
+            if ($strategy->supports($modelType)) {
+                return $strategy->execute($modelType, $confirmation);
+            }
+        }
+        throw new \LogicException('No strategy found for category: ' . $modelType->getCategory()->value);
+    }
+}
+```
+
+Les strategies sont auto-injectées via `#[AutoconfigureTag('app.sync_strategy')]` et le tagged iterator de Symfony.
+
+### DTOs
+
+```php
+class SyncPreviewResult
+{
+    public string $modelTypeId;
+    public string $category;
+    public int $itemCount;
+    public array $additions;    // ['pieceSlots' => int, 'productSlots' => int, ...]
+    public array $deletions;
+    public array $modifications;
+}
+
+class SyncConfirmation
+{
+    public bool $confirmDeletions = false;
+    public bool $confirmTypeChanges = false;
+}
+
+class SyncExecutionResult
+{
+    public int $itemsUpdated;
+    public array $additions;
+    public array $deletions;
+    public array $modifications;
+}
+```
+
+### Controller
+
+```php
+#[Route('/api/model_types/{id}')]
+class ModelTypeSyncController extends AbstractController
+{
+    #[Route('/sync-preview', methods: ['POST'])]
+    #[IsGranted('ROLE_GESTIONNAIRE')]
+    public function preview(ModelType $modelType, Request $request): JsonResponse
+    {
+        $structure = json_decode($request->getContent(), true)['structure'] ?? [];
+        $result = $this->syncService->preview($modelType, $structure);
+        return $this->json($result);
+    }
+
+    #[Route('/sync', methods: ['POST'])]
+    #[IsGranted('ROLE_GESTIONNAIRE')]
+    public function sync(ModelType $modelType, Request $request): JsonResponse
+    {
+        $body = json_decode($request->getContent(), true);
+        $confirmation = new SyncConfirmation();
+        $confirmation->confirmDeletions = $body['confirmDeletions'] ?? false;
+        $confirmation->confirmTypeChanges = $body['confirmTypeChanges'] ?? false;
+        $result = $this->syncService->execute($modelType, $confirmation);
+        return $this->json($result);
+    }
+}
+```
+
+### Atomicité PATCH + Sync
+
+Le frontend enchaîne `PATCH` puis `POST /sync` en deux requêtes HTTP. Le `POST /sync` wrappe toute l'opération dans une transaction DB (`$em->wrapInTransaction()`). Si le sync échoue, les modifications de slots sont rollback. Le PATCH du ModelType (skeleton requirements) reste committée — c'est acceptable car un re-sync est toujours possible.
+
+En cas d'échec réseau entre le PATCH et le sync, le ModelType est à jour mais les items ne sont pas synchronisés. Le prochain save de la catégorie reproposera le sync-preview, qui détectera les différences.
+
+## Logique de Diff / Sync
+
+### Matching des slots
+
+Pour chaque item lié, on compare ses slots actuels avec les skeleton requirements du ModelType. Le matching se fait par **`typeXxxId`** (le type référencé : `typePieceId`, `typeProductId`, `typeComposantId`) + **`position`**.
+
+Il n'y a **pas de FK directe** entre un slot et un skeleton requirement. Le lien est implicite via le type + position.
+
+**Pour le preview :** la strategy parse le `$newStructure` (payload JSON) et le compare aux slots actuels sans toucher à la DB.
+
+**Pour l'execute :** la strategy lit les skeleton requirements actuels (déjà mis à jour par le PATCH) et les compare aux slots actuels.
+
+### Règles — Slots (pièce, produit, sous-composant)
+
+| Cas | Action |
+|-----|--------|
+| Skeleton requirement existe, pas de slot correspondant | **Ajouter** slot vide (type + position, `quantity = 1` pour pièces, pas de sélection) |
+| Slot existe, plus de skeleton requirement | **Supprimer** le slot (si `confirmDeletions`) — sélection perdue |
+| Les deux existent, position différente | **Mettre à jour** la position du slot |
+| Slot existe et matche | **Ne rien toucher** — sélection et quantité préservées |
+
+### Règles — Custom fields
+
+| Cas | Action |
+|-----|--------|
+| Nouveau custom field | **Créer** `CustomFieldValue` vides pour tous les items |
+| Custom field supprimé | **Supprimer** les `CustomFieldValue` (si `confirmDeletions`) |
+| Renommé (même `orderIndex`, nom différent) | **Propagation auto** — label dans la définition, valeurs intactes |
+| Type changé (même `orderIndex`, type différent) | **Clear** les valeurs (si `confirmTypeChanges`) — `CustomFieldValue` conservée, `value` vidée |
+
+Le matching des custom fields se fait par **`orderIndex`** (propriété stable sur l'entité `CustomField`), pas par index de tableau. Cela évite les faux positifs lors de réordonnancement.
+
+## Nouvelle Entité — `PieceProductSlot`
+
+### Contexte — Remplacement de la M2M `piece_products`
+
+Actuellement, les produits liés aux pièces passent par une relation M2M (`piece_products`, colonnes `a`/`b`). Cette table n'a pas de notion de `position`, `typeProductId`, ou `familyCode`.
+
+`PieceProductSlot` **remplace** cette M2M pour uniformiser l'architecture avec les slots des Composants. La M2M existante sera conservée temporairement puis supprimée dans une migration future.
+
+### Table `piece_product_slots`
+
+| Colonne | Type | Contrainte |
+|---------|------|------------|
+| `id` | VARCHAR (CUID) | PK |
+| `pieceid` | VARCHAR | FK → `pieces.id` CASCADE |
+| `typeproductid` | VARCHAR | FK → `model_types.id` SET NULL, nullable |
+| `selectedproductid` | VARCHAR | FK → `products.id` SET NULL, nullable |
+| `familycode` | VARCHAR(255) | nullable |
+| `position` | INT | NOT NULL |
+| `createdat` | TIMESTAMP | NOT NULL |
+| `updatedat` | TIMESTAMP | NOT NULL |
+
+### Entité PHP
+
+```php
+#[ORM\Entity]
+#[ORM\Table(name: 'piece_product_slots')]
+#[ORM\HasLifecycleCallbacks]
+class PieceProductSlot
+{
+    #[ORM\Id]
+    #[ORM\Column(type: 'string')]
+    private string $id;
+
+    #[ORM\ManyToOne(targetEntity: Piece::class, inversedBy: 'productSlots')]
+    #[ORM\JoinColumn(name: 'pieceId', referencedColumnName: 'id', nullable: false, onDelete: 'CASCADE')]
+    private Piece $piece;
+
+    #[ORM\ManyToOne(targetEntity: ModelType::class)]
+    #[ORM\JoinColumn(name: 'typeProductId', referencedColumnName: 'id', nullable: true, onDelete: 'SET NULL')]
+    private ?ModelType $typeProduct = null;
+
+    #[ORM\ManyToOne(targetEntity: Product::class)]
+    #[ORM\JoinColumn(name: 'selectedProductId', referencedColumnName: 'id', nullable: true, onDelete: 'SET NULL')]
+    private ?Product $selectedProduct = null;
+
+    #[ORM\Column(type: 'string', length: 255, nullable: true)]
+    private ?string $familyCode = null;
+
+    #[ORM\Column(type: 'integer')]
+    private int $position = 0;
+
+    #[ORM\Column(type: Types::DATETIME_IMMUTABLE)]
+    private DateTimeImmutable $createdAt;
+
+    #[ORM\Column(type: Types::DATETIME_IMMUTABLE)]
+    private DateTimeImmutable $updatedAt;
+}
+```
+
+### Relation sur Piece
+
+```php
+#[ORM\OneToMany(targetEntity: PieceProductSlot::class, mappedBy: 'piece', cascade: ['persist', 'remove'], orphanRemoval: true)]
+#[ORM\OrderBy(['position' => 'ASC'])]
+private Collection $productSlots;
+```
+
+La relation M2M `$products` existante sur `Piece` sera marquée deprecated puis supprimée dans une migration future.
+
+### Migration
+
+1. Créer la table `piece_product_slots`
+2. Migrer les données existantes de `piece_products` (M2M) → chaque entrée devient un `PieceProductSlot` avec `selectedProductId` renseigné, `typeProductId` déduit du produit sélectionné (`product.typeProduct`), `position` auto-incrémentée
+3. Conserver `piece_products` temporairement (suppression dans une migration future)
+4. Mettre à jour le virtual getter `getStructure()` de Piece pour lire les `productSlots`
+
+## Versioning
+
+### Nouveau champ sur Composant, Piece, Product
+
+```php
+#[ORM\Column(type: 'integer', options: ['default' => 1])]
+#[Groups(['composant:read'])]  // idem pour piece:read, product:read
+private int $version = 1;
+```
+
+### Comportement
+
+- **Création** d'un item → `version = 1`
+- **Sync** qui modifie les slots ou custom fields d'un item → `version += 1`
+- Si la sync n'a aucun impact sur un item particulier (ses slots matchent déjà le skeleton), sa version ne change pas
+
+### Migration
+
+```sql
+ALTER TABLE composants ADD COLUMN IF NOT EXISTS version INT NOT NULL DEFAULT 1;
+ALTER TABLE pieces ADD COLUMN IF NOT EXISTS version INT NOT NULL DEFAULT 1;
+ALTER TABLE products ADD COLUMN IF NOT EXISTS version INT NOT NULL DEFAULT 1;
+```
+
+## Frontend
+
+### Suppression du `restrictedMode`
+
+**Fichiers à supprimer :**
+- `composables/useCategoryEditGuard.ts`
+- `tests/composables/useCategoryEditGuard.test.ts`
+
+**Fichiers à modifier (retirer restrictedMode) :**
+- `pages/component-category/[id]/edit.vue`
+- `pages/piece-category/[id]/edit.vue`
+- `pages/product-category/[id]/edit.vue`
+- `components/StructureNodeEditor.vue`
+- `components/PieceModelStructureEditor.vue`

+- `composables/usePieceStructureEditorLogic.ts`
+- `tests/components/ModelTypeForm.test.ts` (si existant)
+- `tests/components/PieceModelStructureEditor.test.ts`
+
+### Nouveau composant — `SyncConfirmationModal.vue`
+
+Modal DaisyUI qui reçoit un `SyncPreviewResult` et affiche :
+
+```
+Cette modification impacte X [composants|pièces|produits] :
+
+Ajouts :
+  • Y slots pièce à créer
+  • Z valeurs de champs personnalisés à initialiser
+
+Suppressions :
+  • W slots produit à supprimer (les sélections seront perdues)
+
+Modifications :
+  • V valeurs de champs à réinitialiser (changement de type)
+
+[Annuler]  [Confirmer la synchronisation]
+```
+
+### Nouveau service — `modelTypes.ts`
+
+Ajout de deux fonctions au service existant :
+
+```typescript
+export function syncPreview(id: string, structure: any) {
+  return requestFetch(`/api/model_types/${id}/sync-preview`, {
+    method: 'POST',
+    headers: { 'Content-Type': 'application/json' },
+    body: JSON.stringify({ structure }),
+  })
+}
+
+export function syncExecute(id: string, confirmation: { confirmDeletions: boolean, confirmTypeChanges: boolean }) {
+  return requestFetch(`/api/model_types/${id}/sync`, {
+    method: 'POST',
+    headers: { 'Content-Type': 'application/json' },
+    body: JSON.stringify(confirmation),
+  })
+}
+```
+
+### Flow dans les pages d'édition de catégorie
+
+```typescript
+const handleSubmit = async (payload) => {
+  // 1. Preview (avant le save)
+  const preview = await syncPreview(id, payload.structure)
+
+  const hasImpact = preview.itemCount > 0 && (
+    Object.values(preview.additions).some(v => v > 0) ||
+    Object.values(preview.deletions).some(v => v > 0) ||
+    Object.values(preview.modifications).some(v => v > 0)
+  )
+
+  // 2. Si impact, demander confirmation
+  if (hasImpact) {
+    pendingPayload.value = payload
+    syncPreviewData.value = preview
+    showSyncModal.value = true
+    return
+  }
+
+  // 3. Pas d'impact → save direct (PATCH + sync)
+  await saveAndSync(payload, { confirmDeletions: false, confirmTypeChanges: false })
+}
+
+const onSyncConfirmed = async () => {
+  const preview = syncPreviewData.value
+  const needsDeleteConfirm = Object.values(preview.deletions).some(v => v > 0)
+  const needsTypeChangeConfirm = preview.modifications.customFieldTypeChanges > 0
+
+  await saveAndSync(pendingPayload.value, {
+    confirmDeletions: needsDeleteConfirm,
+    confirmTypeChanges: needsTypeChangeConfirm,
+  })
+}
+
+const saveAndSync = async (payload, confirmation) => {
+  await updateModelType(id, payload)
+  await syncExecute(id, confirmation)
+  showSuccess('Catégorie mise à jour et synchronisée.')
+  router.push('/...')
+}
+```
+
+## Non-régression
+
+### Machines
+
+- Le `MachineStructureController` lit les slots des composants. La sync modifie ces slots → les machines affichent automatiquement la dernière version au prochain chargement.
+- Aucun changement dans le controller machine.
+
+### Quantités
+
+- La sync **ne touche jamais** aux slots qui matchent toujours un skeleton requirement. Les quantités (`ComposantPieceSlot.quantity`) et sélections existantes sont préservées.
+- Les nouveaux slots ajoutés par la sync ont `quantity = 1` par défaut.
+- Le `ComposantPieceSlotController` (PATCH quantity) reste inchangé.
+
+### `PieceProductSlot` — pas de quantité
+
+Cohérent avec `ComposantProductSlot` qui n'a pas de quantité non plus.
+
+### Relation M2M `piece_products`
+
+La M2M existante reste en base pendant la période de transition. Le code frontend/backend qui la lit devra être migré vers les `productSlots`. La M2M sera supprimée dans une migration future une fois que tout le code utilise les slots.
+
+## Tests
+
+### Backend — PHPUnit
+
+- `ModelTypeSyncControllerTest` — tests des endpoints preview et sync (y compris erreurs 403/404, confirmations partielles)
+- `ComposantSyncStrategyTest` — logique de diff pour composants (ajout, suppression, position update, no-op)
+- `PieceSyncStrategyTest` — logique de diff pour pièces (ajout/suppression de product slots)
+- `ProductSyncStrategyTest` — logique de diff pour produits (custom fields only)
+- `PieceProductSlotTest` — CRUD de la nouvelle entité
+- Idempotence : vérifier qu'un double appel à `sync` est un no-op
+- Vérifier la non-régression : `MachineStructureControllerTest` existant doit passer sans modification
+
+### Frontend — Tests
+
+- Supprimer `tests/composables/useCategoryEditGuard.test.ts`
+- Mettre à jour `tests/components/PieceModelStructureEditor.test.ts` (retirer restrictedMode)
+- Ajouter tests pour le flow sync dans les pages d'édition (preview → modal → confirm → save)
+
+## Performance
+
+Pour le volume attendu (dizaines d'items par catégorie, pas de milliers), la sync en PHP avec l'ORM Doctrine est suffisante. Si le volume augmente significativement, les opérations de création/suppression de slots pourront être converties en batch SQL (INSERT ... SELECT, DELETE ... WHERE) sans changer l'architecture (la strategy encapsule la logique).

+# MCP Server — Inventory Project — Design Spec
+
+**Date :** 2026-03-16
+**Version projet :** 1.9.1
+**Statut :** Draft (post-review v2)
+
+---
+
+## 1. Objectif
+
+Exposer l'intégralité de l'API Inventory (machines, pièces, composants, produits, sites, constructeurs, custom fields, documents, commentaires, audit) via un serveur MCP (Model Context Protocol) intégré directement dans l'application Symfony.
+
+Le serveur doit être compatible avec tous les clients MCP majeurs : Claude Code, Claude Desktop, ChatGPT Desktop, Codex, et tout client supportant le protocole MCP.
+
+## 2. Contraintes
+
+| Contrainte | Détail |
+|---|---|
+| **Réseau** | Machine hébergée sur un réseau fermé d'entreprise. Les clients distants (Claude Desktop, ChatGPT, Codex) accèdent via un tunnel chiffré (Cloudflare/WireGuard/SSH) |
+| **Auth** | Pass-through : chaque client fournit ses propres credentials (profileId + password). Le serveur MCP charge le profil correspondant et applique ses rôles. Les actions sont traçables par utilisateur dans l'audit log |
+| **Transport** | Dual : stdio pour usage local (Claude Code sur la même machine) + HTTP Streamable/SSE pour clients distants via tunnel |
+| **Stack** | PHP / Symfony 8.0 — le serveur MCP vit dans l'application existante, pas de service séparé |
+| **Scope** | Lecture + écriture complète — les outils couvrent tout le CRUD + les opérations métier |
+
+## 3. Stack technique
+
+| Composant | Choix |
+|---|---|
+| SDK MCP | `symfony/mcp-bundle` v0.6.0 + `mcp/sdk` ^0.4 (officiel Symfony + PHP Foundation + Anthropic) |
+| Transport stdio | `bin/console mcp:server` (dans le container Docker) |
+| Transport HTTP | Endpoint `/_mcp` sur le même port que l'API (8081) |
+| Auth HTTP | Custom Symfony Authenticator (`McpHeaderAuthenticator`) intégré au firewall Symfony |
+| Auth stdio | Token synthétique chargé depuis `$_ENV` au boot |
+| Rate limiting | `symfony/rate-limiter` sur les tentatives d'auth échouées |
+| Accès données | Repositories Doctrine directs (pas de hop HTTP interne) |
+
+**Note :** Le bundle est expérimental et non couvert par la BC Promise de Symfony. L'implémentation inclut un spike/PoC initial (étape 1 du plan) pour valider la compatibilité de l'API réelle du bundle avec ce design.

+Le serveur MCP accède directement aux repositories Doctrine et aux services Symfony existants. Pas de double sérialisation — les tools appellent les mêmes repositories/services que les controllers REST.
+
+## 5. Authentification pass-through
+
+### 5.1 Firewall Symfony — intégration sécurité
+
+Un firewall dédié pour `/_mcp` avec un authenticator custom. Cela garantit que `$security->getUser()` retourne le bon Profile, que la hiérarchie des rôles fonctionne via `is_granted()`, et que l'audit log trace le bon acteur.
+
+```yaml
+# config/packages/security.yaml (ajout)
+security:
+    firewalls:
+        mcp:
+            pattern: ^/_mcp
+            stateless: true
+            custom_authenticators:
+                - App\Mcp\Security\McpHeaderAuthenticator
+```
+
+Le `McpHeaderAuthenticator` implémente `AuthenticatorInterface` :
+1. Extrait `X-Profile-Id` et `X-Profile-Password` des headers
+2. Charge le profil via `ProfileRepository`
+3. Vérifie le password hash via `UserPasswordHasherInterface`
+4. Retourne un `Passport` avec le Profile comme User
+5. Symfony gère le reste (token, rôles, hiérarchie)
+
+Cela permet à `AbstractAuditSubscriber.resolveActorProfileId()` de résoudre l'acteur via `$security->getUser()` sans aucune modification du code existant.
+
+### 5.2 Transport stdio — token synthétique
+
+Pour le transport stdio (pas de requête HTTP), un `EventSubscriber` sur `console.command` (quand la commande est `mcp:server`) :
+1. Lit `MCP_PROFILE_ID` et `MCP_PROFILE_PASSWORD` depuis `$_ENV`
+2. Valide les credentials
+3. Injecte un `UsernamePasswordToken` synthétique dans le `TokenStorage` avec le Profile
+
+### 5.3 Rate limiting — protection brute-force
+
+```yaml
+# config/packages/rate_limiter.yaml
+framework:
+    rate_limiter:
+        mcp_auth:
+            policy: sliding_window
+            limit: 5
+            interval: '1 minute'
+```
+
+Le `McpHeaderAuthenticator` consomme le rate limiter sur chaque tentative échouée (clé = IP). Après 5 échecs en 1 minute, toute tentative est rejetée avec une erreur MCP `429 Too Many Requests`.
+
+### 5.4 Vérification des rôles
+
+Chaque tool déclare un rôle minimum. L'authenticator Symfony gère la hiérarchie :
+
+| Rôle | Droits MCP |
+|---|---|
+| `ROLE_VIEWER` | Tous les tools de lecture (list, get, search, history) |
+| `ROLE_GESTIONNAIRE` | Lecture + écriture (create, update, delete, slots, clone) |
+| `ROLE_ADMIN` | Tout + gestion profils |
+
+Les tools utilisent `$this->security->isGranted('ROLE_XXX')` pour vérifier, bénéficiant de la hiérarchie Symfony standard.

+
+### 6.13 Tools — ModelTypes
+
+| Tool | Description | Rôle min |
+|---|---|---|
+| `list_model_types` | Lister les ModelTypes par catégorie avec skeleton requirements | VIEWER |

+
+**Total : ~55 tools** (splittés pour des schémas JSON non-ambigus, meilleure compatibilité LLM)
+
+> **Note :** Les tools d'administration des profils (`list_profiles`, `create_profile`, etc.) ne sont pas inclus — la gestion des profils reste exclusivement via l'API REST `/api/admin/profiles` (ROLE_ADMIN). Cela évite d'exposer la gestion des comptes/mots de passe via MCP.
+
+## 7. Resources MCP
+
+| URI | Description | Contenu |
+|---|---|---|
+| `inventory://schema/entities` | Schéma de toutes les entités | Nom, champs (nom, type, nullable, description) pour chaque entité |
+| `inventory://model-types/{category}` | ModelTypes par catégorie | Liste des ModelTypes avec leurs skeleton requirements et custom fields |
+| `inventory://roles` | Hiérarchie des rôles | Rôles et permissions associées pour guider le LLM |
+| `inventory://stats` | Statistiques globales | Compteurs de chaque entité, commentaires ouverts |
+
+## 8. Workflows de création guidés
+
+### 8.1 Créer un Composant complet
+
+```
+1. list_model_types(category: "composant")
+   → Choisir le type de composant
+
+2. get_model_type(modelTypeId)
+   → Voir les skeleton requirements : pièces, produits, sous-composants attendus
+   → Voir les custom fields de chaque requirement
+
+3. create_composant(name, reference, modelTypeId, constructeurs)
+   → Reçoit: { id, slots: [{slotId, type, requirementName}, ...] }
+
+4. search_inventory(query: "Roulement", types: ["piece"])
+   → Trouver les pièces candidates pour chaque slot
+
+5. update_slots([{slotId, selectedPieceId}, {slotId, selectedProductId}, ...])
+   → Remplir les slots
+
+6. upsert_custom_field_values(entityType: "composant", entityId,
+     fields: [{name: "Tension", value: "220V"}, ...])
+   → Remplir les custom fields
+```
+
+### 8.2 Créer une Pièce complète
+
+```
+1. list_model_types(category: "piece")
+2. get_model_type(modelTypeId)
+3. create_piece(name, reference, modelTypeId, constructeurs)
+   → Reçoit: { id, productSlots: [{slotId, requirementName}, ...] }
+4. search_inventory(query: "...", types: ["product"])
+5. update_slots([{slotId, selectedProductId}, ...])
+6. upsert_custom_field_values(...)
+```
+
+### 8.3 Créer un Produit
+
+```
+1. list_model_types(category: "product")
+2. create_product(name, reference, modelTypeId, prix, constructeurs)
+3. upsert_custom_field_values(...)
+```
+
+### 8.4 Créer une Machine complète (de bas en haut)
+
+```
+1. Créer les produits nécessaires (§8.3)
+2. Créer les pièces avec les produits dans les slots (§8.2)
+3. Créer les composants avec les pièces dans les slots (§8.1)
+4. list_sites → choisir le site
+5. create_machine(name, reference, siteId, constructeurs)
+6. add_machine_links(machineId, links: [
+     {type: "composant", entityId, quantity},
+     {type: "piece", entityId, quantity},
+     {type: "product", entityId}
+   ])
+7. upsert_custom_field_values(entityType: "machine", machineId, ...)
+```
+
+## 9. Pagination
+
+Toutes les tools `list_*` utilisent un contrat de pagination uniforme :
+
+### Paramètres d'entrée
+
+| Paramètre | Type | Default | Description |
+|---|---|---|---|
+| `page` | int | 1 | Numéro de page (1-indexed) |
+| `limit` | int | 30 | Nombre d'items par page (max 100) |
+
+### Format de réponse
+
+```json
+{
+  "items": [...],
+  "total": 142,
+  "page": 1,
+  "limit": 30,
+  "pageCount": 5
+}
+```
+
+## 10. Format des erreurs
+
+Toutes les erreurs MCP suivent un format uniforme via `isError: true` dans la réponse tool :
+
+```json
+{
+  "isError": true,
+  "content": [{"type": "text", "text": "Permission denied: ROLE_GESTIONNAIRE required for create_machine"}]
+}
+```
+
+### Catégories d'erreurs
+
+| Code | Description | Exemple |
+|---|---|---|
+| `auth_error` | Credentials invalides ou manquants | "Authentication failed: invalid password" |
+| `permission_denied` | Rôle insuffisant pour l'opération | "Permission denied: ROLE_GESTIONNAIRE required" |
+| `not_found` | Entité introuvable | "Machine not found: cl4a8b..." |
+| `validation_error` | Données invalides | "Validation failed: name is required" |
+| `rate_limited` | Trop de tentatives d'auth échouées | "Rate limited: try again in 45 seconds" |
+| `internal_error` | Erreur serveur inattendue | "Internal error: database connection failed" |
+
+Le champ `text` inclut toujours la catégorie en préfixe pour que le LLM puisse adapter son comportement.
+

+
+## 12. Configuration des clients
+
+### 12.1 Claude Code (local, stdio via Docker)
+
+Fichier `.mcp.json` à la racine du projet :
+
+```json
+{
+  "mcpServers": {
+    "inventory": {
+      "command": "docker",
+      "args": [
+        "exec", "-i",
+        "-e", "MCP_PROFILE_ID=<votre-profile-id>",
+        "-e", "MCP_PROFILE_PASSWORD=<votre-password>",
+        "php-inventory-apache",
+        "php", "bin/console", "mcp:server"
+      ]
+    }
+  }
+}
+```
+
+> **Note :** Les env vars sont passées via les flags `-e` de `docker exec` car le bloc `env` de `.mcp.json` ne les injecte pas dans le container Docker. Si PHP et les dépendances Composer sont disponibles directement sur l'hôte (hors Docker), on peut utiliser `"command": "php", "args": ["bin/console", "mcp:server"]` avec un bloc `env` standard.
+
+### 12.2 Claude Desktop (distant, HTTP via tunnel)
+
+Fichier `claude_desktop_config.json` :
+
+```json
+{
+  "mcpServers": {
+    "inventory": {

+        "X-Profile-Password": "<votre-password>"
+      }
+    }
+  }
+}
+```
+
+### 12.3 ChatGPT Desktop (HTTP via tunnel)
+
+Même principe HTTP : URL du tunnel + headers d'auth. Format de config selon la doc ChatGPT MCP.
+

+## 14. Documentation utilisateur (docs/mcp/README.md)
+
+Le guide contiendra :
+
+1. **Introduction** — Qu'est-ce que le MCP Inventory, à quoi ça sert, quels clients sont supportés
+2. **Prérequis** — Profil avec rôle suffisant, accès au tunnel, client MCP compatible
+3. **Installation & configuration par client** — Exemples copier-coller pour :
+   - Claude Code (stdio via Docker)
+   - Claude Desktop (HTTP via tunnel)
+   - ChatGPT Desktop (HTTP via tunnel)
+   - Codex (HTTP via tunnel)
+4. **Catalogue des tools** — Tableau complet avec nom, description, paramètres, rôle requis
+5. **Workflows guidés** — Comment créer une machine, un composant, une pièce, un produit (étape par étape avec exemples d'appels)
+6. **Resources disponibles** — URIs et contenu exposé
+7. **Rôles & permissions** — Quel rôle permet quelles actions
+8. **Format des erreurs** — Catégories et exemples
+9. **Limitations connues** — Upload documents non supporté via MCP
+10. **Troubleshooting** — Erreurs courantes (auth failed, tunnel down, rôle insuffisant, rate limited)
+
+## 15. Sécurité
+
+| Mesure | Détail |
+|---|---|
+| **Firewall Symfony** | `/_mcp` a son propre firewall avec `McpHeaderAuthenticator` — intégré au système de sécurité standard |
+| **Vérification rôle** | Chaque tool vérifie via `$security->isGranted()` avec hiérarchie des rôles |
+| **Audit trail** | `AbstractAuditSubscriber.resolveActorProfileId()` fonctionne nativement car `$security->getUser()` retourne le Profile authentifié |
+| **Rate limiting** | 5 tentatives d'auth échouées par minute par IP → rejet |
+| **Transport chiffré** | Le tunnel assure le chiffrement en transit pour les clients distants |
+| **Pas de secrets dans le code** | Credentials dans env vars (stdio) ou headers (HTTP), jamais en dur |
+| **Sessions MCP** | TTL 1h, stockage fichier, nettoyage automatique |
+| **CORS** | Non nécessaire — les clients MCP sont des apps natives (pas des navigateurs). Le tunnel termine la connexion côté serveur. À réévaluer si un client browser-based apparaît |
+
+## 16. Backward Compatibility
+
+Les tools MCP suivent une politique additive :
+- **Ajouts** : nouveaux tools, nouveaux paramètres optionnels → toujours OK
+- **Suppressions** : marquer un tool comme deprecated pendant 1 version avant suppression
+- **Breaking changes** : changer le type/nom d'un paramètre requis → bumper la version MCP
+
+Le champ `version` dans la config MCP (lu depuis `VERSION`) signale les changements.
+
+## 17. Dépendances à installer
+
+```bash
+composer require symfony/mcp-bundle symfony/rate-limiter
+```
+
+Le bundle tire `mcp/sdk` automatiquement.
+
+## 18. Tests
+
+Les tools MCP seront testés via :
+
+- **Tests unitaires** : chaque tool testé avec des mocks de repositories, vérification des paramètres et des réponses
+- **Tests d'intégration** : appels MCP stdio via `docker exec ... php bin/console mcp:server` avec des fixtures
+- **Tests de sécurité** : vérification que les tools rejettent les appels sans auth, avec rôle insuffisant, et après rate limiting
+- Pattern : hériter de `AbstractApiTestCase` pour réutiliser les factories existantes (`createProfile()`, `createMachine()`, etc.)
+
+## 19. Spike / PoC initial
+
+Avant l'implémentation complète, une étape de validation :
+
+1. Installer `symfony/mcp-bundle` dans le projet
+2. Créer un tool minimal (`get_dashboard_stats`) avec l'attribut `#[McpTool]`
+3. Tester le transport stdio : `docker exec -i php-inventory-apache php bin/console mcp:server`
+4. Tester le transport HTTP : appel POST sur `/_mcp`
+5. Valider que l'authenticator custom fonctionne avec le firewall
+6. Confirmer que `$security->getUser()` retourne le bon Profile dans un tool
+
+Si le PoC révèle des incompatibilités avec l'API du bundle, adapter le design avant de continuer.
