+# NATS dans oc-scheduler
+
+## Vue d'ensemble
+
+`oc-scheduler` utilise NATS comme bus d'événements pour deux objectifs :
+
+1. **Recevoir les planners** (disponibilité des ressources) publiés par `oc-discovery`.
+2. **Réagir aux modifications de workflows** pour diffuser un planner actualisé et signaler les streams WebSocket actifs.
+
+Tout le code NATS se trouve dans `infrastructure/nats.go`.
+
+---
+
+## Canaux écoutés
+
+### `PROPALGATION_EVENT` — réception des planners
+
+**Condition d'acceptation :** `resp.FromApp == "oc-discovery"` et `prop.Action == PB_PLANNER`.
+
+**Ce qui se passe :**
+- Le payload est désérialisé en `planner.Planner`.
+- Le champ `peer_id` est extrait pour identifier le pair.
+- Le planner est stocké dans `PlannerCache[peerID]` via `storePlanner()`.
+- Si c'est la **première apparition** de ce `peerID` dans le cache, une goroutine de TTL est lancée (voir §TTL ci-dessous).
+- Tous les abonnés en attente d'un changement sur ce `peerID` sont notifiés.
+
+### `CREATE_RESOURCE` — modification d'un workflow
+
+**Condition d'acceptation :** `resp.Datatype == WORKFLOW`.
+
+**Ce qui se passe :**
+1. Le payload est désérialisé en `workflow.Workflow`.
+2. `broadcastPlanner(wf)` est appelé : pour chaque pair (storage + compute) du workflow dont le planner **n'est pas encore en cache**, un événement `PB_PLANNER` est émis sur NATS afin de demander un planner frais à `oc-discovery`.
+3. `notifyWorkflowWatchers(wf.GetID())` est appelé : tous les streams WebSocket qui observent ce workflow sont signalés pour **rafraîchir leur liste de pairs surveillés**.
+
+---
+
+## Canaux émis
+
+### `PROPALGATION_EVENT` — deux actions possibles
+
+| Action | Déclencheur | Effet attendu |
+|---|---|---|
+| `PB_PLANNER` | Workflow modifié, pair inconnu du cache | `oc-discovery` renvoie le planner du pair |
+| `PB_CLOSE_PLANNER` | TTL expiré **ou** déconnexion WebSocket | Les consommateurs (oc-discovery, autres schedulers) libèrent leur état pour ce pair |
+
+---
+
+## Cache des planners (`PlannerCache`)
+
+```
+PlannerCache : map[string]*planner.Planner   // clé = peerID
+plannerAddedAt : map[string]time.Time        // horodatage de première insertion
+```
+
+- Protégé par `plannerMu` (RWMutex).
+- Alimenté uniquement via `storePlanner()` (appelé par le listener NATS).
+- Supprimé via `EmitNATS(peerID, PB_CLOSE_PLANNER)`, qui efface l'entrée **et** notifie les abonnés.
+
+### TTL de 24 heures
+
+À la **première** insertion d'un `peerID`, une goroutine est lancée :
+
+```
+sleep(24h)
+→ si l'entrée existe encore : EmitNATS(peerID, PB_CLOSE_PLANNER)
+```
+
+Cela évite que des planners obsolètes stagnent indéfiniment. L'entrée est supprimée et les streams actifs reçoivent une notification « plus de planner » pour ce pair.
+
+---
+
+## Pub/sub interne
+
+Un registre d'abonnements en mémoire permet à d'autres composants (notamment le controller WebSocket) de réagir aux événements sans coupler directement le code NATS et les goroutines HTTP.
+
+Deux registres distincts :
+
+| Registre | Clé | Signification |
+|---|---|---|
+| `plannerSubs` | `peerID` | « le planner de ce pair a changé » |
+| `workflowSubs` | `workflowID` | « ce workflow a été modifié » |
+
+### API
+
+```go
+// S'abonner aux changements de planners pour plusieurs pairs
+ch, cancel := SubscribePlannerUpdates(peerIDs []string)
+
+// S'abonner aux modifications d'un workflow
+ch, cancel := SubscribeWorkflowUpdates(wfID string)
+```
+
+Chaque canal est bufférisé (`capacity 1`) : si un signal est déjà en attente, les suivants sont ignorés sans bloquer.
+
+---
+
+## Intégration avec le stream WebSocket (`GET /oc/:id/check`)
+
+Le handler `CheckStream` dans `controllers/workflow_sheduler.go` exploite ces mécanismes :
+
+1. **Ouverture** : résolution des `peerIDs` du workflow, abonnement à `SubscribePlannerUpdates` et `SubscribeWorkflowUpdates`.
+2. **Boucle de streaming** :
+   - `plannerCh` reçoit un signal → re-calcul du `CheckResult` et envoi au client.
+   - `wfCh` reçoit un signal (workflow modifié) → recalcul des `peerIDs`, désabonnement + ré-abonnement aux nouveaux pairs, re-calcul et envoi.
+3. **Fermeture** (déconnexion client) :
+   - Désabonnement des deux registres.
+   - `EmitNATS(peerID, PB_CLOSE_PLANNER)` pour **chaque pair surveillé** : le cache est purgé et `oc-discovery` est informé que le scheduler n'a plus besoin du planner.
+
