+
+## 1. Bugs critiques corrigés dans cette session
+
+| Fichier | Ligne | Description | Statut |
+|---------|-------|-------------|--------|
+| `entrypoint.go` | 652, 664, 676, 688 | `fmt.Errorf(res.Err)` → format string non-constant (erreur de build) | ✅ Corrigé |
+| `models/utils/abstracts.go` | 136 | `VerifyAuth` déréférençait `request.Admin` avant de vérifier `request != nil` | ✅ Corrigé |
+| `models/utils/abstracts.go` | 68-78 | `DeepCopy()` faisait `Unmarshal` dans un pointeur nil → retournait toujours `nil` | ✅ Corrigé |
+| `models/resources/resource.go` | 176 | `instances = append(instances)` — argument manquant, l'instance n'était jamais ajoutée | ✅ Corrigé |
+| `models/resources/priced_resource.go` | 63-69 | Code mort après `return true` dans `IsBooked()` | ✅ Corrigé |
+| `tools/remote_caller.go` | 118 | `CallDelete` vérifiait `req.Body == nil` (toujours vrai pour DELETE), court-circuitant la lecture de la réponse | ✅ Corrigé |

+## 2. Debug prints à supprimer (fmt.Println en production)
+
+Ces appels `fmt.Println` polluent stdout et peuvent exposer des informations sensibles.
+
+| Fichier | Lignes | Contenu |
+|---------|--------|---------|
+| `models/bill/bill.go` | ~197 | `fmt.Println(err)` |
+| `models/collaborative_area/collaborative_area_mongo_accessor.go` | ~95, 109, 118, 123 | Debug sur `res`, `sharedWorkspace.AllowedPeersGroup`, `canFound`, `peerskey` |
+| `models/peer/peer_cache.go` | ~44, 55 | URL et `"Launching peer execution on..."` |
+| `models/resources/storage.go` | ~196 | `fmt.Println("GetPriceHT", ...)` |
+| `models/workflow/workflow.go` | ~158, 164, 170, 176 | 4× `fmt.Println(err)` |
+| `tools/nats_caller.go` | ~110, 117, 122, 126 | 4× `fmt.Println()` divers |
+| `tools/remote_caller.go` | 227 | `fmt.Println("Error reading the body...")` (devrait utiliser le logger) |
+| `dbs/dbs.go` | 47 | `fmt.Println("Recovered. Error:\n", r, debug.Stack())` |
+
+> **Note :** `priced_resource.go` et `data.go` corrigés dans cette session.
+
+---
+
+## 3. Code commenté significatif
+
+### 3.1 Validation de pricing désactivée (workflow)
+**Fichier :** `models/workflow/workflow.go` — ~lignes 631-634
+```go
+// Should be commented once the Pricing selection feature has been implemented
+// if priced.SelectPricing() == nil {
+//     return resources, priceds, errors.New("no pricings are selected... can't proceed")
+// }
+```
+Une vérification de sécurité critique est désactivée. Sans elle, des ressources sans pricing peuvent être traitées silencieusement.
+
+### 3.2 PAY_PER_USE — stratégie supprimée mais traces restantes
+**Fichier :** `models/common/pricing/pricing_strategy.go` — lignes 47, 61-63
+```go
+// PAY_PER_USE  // per request. ( unpredictible )
+/*case PAY_PER_USE:
+    return bs, true*/
+```
+La constante `PAY_PER_USE` a été supprimée mais les commentaires laissés créent de la confusion.
+
+### 3.3 Vérification d'autorisation peer désactivée
+**Fichier :** `models/resources/resource.go` — lignes 98-104
+```go
+/*if ok, _ := utils.IsMySelf(request.PeerID, ...); ok {*/
+profile = pricing.GetDefaultPricingProfile()
+/*} else {
+    return nil, errors.New("no pricing profile found")
+}*/
+```
+Le profil par défaut est retourné sans vérifier si le pair est bien `myself`. Sécurité à revoir.
+
+---
+
+## 4. Logique erronée non corrigée (à traiter)
+
+### 4.1 IsTimeStrategy — logique inversée
+**Fichier :** `models/common/pricing/pricing_strategy.go` — ligne 88
+```go
+func IsTimeStrategy(i int) bool {
+    return len(TimePricingStrategyList()) < i  // BUG: devrait être ">"
+}
+```
+La condition est inversée. Retourne `true` pour des valeurs hors de la liste. Fonction actuellement non utilisée (voir §5).
+
+### 4.2 IsBillingStrategyAllowed — case SUBSCRIPTION sans retour
+**Fichier :** `models/common/pricing/pricing_strategy.go` — lignes 54-65
+```go
+case SUBSCRIPTION:
+    /*case PAY_PER_USE:
+    return bs, true*/
+// Aucun return ici → tombe dans le default
+```
+Le cas `SUBSCRIPTION` ne retourne rien explicitement, ce qui est trompeur.
+
+---
+
+## 5. Éléments inutilisés
+
+### 5.1 Fonction jamais appelée
+| Symbole | Fichier | Ligne |
+|---------|---------|-------|
+| `IsTimeStrategy(i int) bool` | `models/common/pricing/pricing_strategy.go` | 88 |
+
+De plus, cette fonction a une logique erronée (voir §4.1).
+
+### 5.2 Variable singleton inutilisée
+| Symbole | Fichier | Ligne |
+|---------|---------|-------|
+| `HTTPCallerInstance` | `tools/remote_caller.go` | 57 |
+
+Déclarée comme singleton mais jamais utilisée — de nouvelles instances sont créées via `NewHTTPCaller()`.
+
+---
+
+## 6. Tests supprimés (couverture perdue)
+
+Les fichiers suivants ont été supprimés sur la branche `feature/event` et la couverture correspondante n'est plus assurée :
+
+| Fichier supprimé | Modèles non couverts |
+|------------------|----------------------|
+| `models/peer/tests/peer_cache_test.go` | `PeerCache` — logique d'exécution distribuée |
+| `models/peer/tests/peer_test.go` | `Peer` — modèle et accesseur |
+| `models/utils/tests/abstracts_test.go` | `AbstractObject` — méthodes de base |
+| `models/utils/tests/common_test.go` | `GenericStoreOne`, `GenericDeleteOne`, etc. |
+| `models/workflow_execution/tests/workflow_test.go` | `WorkflowExecution` — modèle et accesseur |
+
+> `models/order/tests/order_test.go` existe mais ne contient **aucune fonction de test**.
+
+---
+
+## 7. Fautes d'orthographe dans les identifiants publics
+
+Ces typos sont dans des noms exportés (API publique) — les corriger est un **breaking change**.
+
+### 7.1 `Instanciated` → `Instantiated`
+Apparaît 50+ fois dans les types exportés centraux :
+- `AbstractInstanciatedResource[T]` (resource.go, compute.go, data.go, storage.go, processing.go, workflow.go)
+- `AbstractInstanciatedResource.Instances`
+- Tests : `resources.AbstractInstanciatedResource[*MockInstance]{...}`
+
+### 7.2 `ressource` → `resource` (dans les messages d'erreur)
+**Fichier :** `entrypoint.go` — messages dans `LoadOneStorage`, `LoadOneComputing`, etc.
+```go
+"Error while loading storage ressource " + storageId  // "ressource" est du français
+```
+
+### 7.3 `GARANTED` → `GUARANTEED`
+**Fichiers :** `models/common/pricing/pricing_profile.go`, `models/resources/storage.go`
+```go
+GARANTED_ON_DELAY        // pricing_profile.go:72
+GARANTED                 // pricing_profile.go:73
+GARANTED_ON_DELAY_STORAGE // storage.go:106
+GARANTED_STORAGE         // storage.go:107
+```
+
+### 7.4 `CREATE_EXECTUTION` → `CREATE_EXECUTION`
+**Fichier :** `tools/nats_caller.go` — ligne 34
+```go
+CREATE_EXECTUTION  // faute de frappe dans la constante enum
+```
+
+### 7.5 `PROPALGATION` → `PROPAGATION`
+**Fichier :** `tools/nats_caller.go` — lignes 29, 45, 56
+```go
+"propalgation event"  // et PROPALGATION_EVENT
+```
+
+---
+
+## 8. Incohérences de nommage mineures
+
+| Fichier | Problème |
+|---------|----------|
+| `models/resources/interfaces.go:19` | Paramètre `instance_id` en snake_case dans une signature Go (devrait être `instanceID`) |
+| `entrypoint.go:505` | Message de panique dans `CopyOne` dit `"Panic recovered in UpdateOne"` |
+| `tools/remote_caller.go:110` | Commentaire `// CallPut calls the DELETE method` (copie-colle incorrect) |
+
+---
+
+## 9. Résumé
+
+| Catégorie | Nombre | Priorité |
+|-----------|--------|----------|
+| Bugs critiques corrigés | 6 | ✅ Fait |
+| Debug `fmt.Println` restants | 15+ | 🔴 Haute |
+| Code commenté important | 3 | 🟠 Moyenne |
+| Logique erronée (non corrigée) | 2 | 🟠 Moyenne |
+| Éléments inutilisés | 2 | 🟡 Faible |

+# PlantUML — Format de commentaire human-readable
+
+Ce document décrit la syntaxe des commentaires attachés aux ressources et aux liens
+dans les fichiers PlantUML importés par OpenCloud.
+
+---
+
+## Syntaxe générale
+
+```plantuml
+TypeRessource(varName, "Nom affiché") ' clé: valeur, clé.sous_clé: valeur
+```
+
+### Règles de parsing
+
+| Règle | Détail |
+|---|---|
+| Séparateur de paires | `,` |
+| Séparateur clé/valeur | premier `:` de la paire (les URLs `http://...` sont gérées) |
+| Sous-objets | notation pointée `access.container.image: nginx` |
+| Types | auto-inférés : `bool` > `float64` > `string` |
+| Fallback | JSON brut si le commentaire commence par `{` (compatibilité ascendante) |
+
+### Comportement à l'import
+
+Chaque ressource reçoit automatiquement une **instance par défaut**, seedée avec les
+attributs de la ressource parente. Le commentaire vient ensuite **surcharger** uniquement
+les champs explicitement renseignés.
+
+> **Exception :** `WorkflowEvent` n'a pas d'instance (voir section dédiée).
+
+---
+
+## Ressources disponibles
+
+### `Data(var, "nom")` — Données
