+## 1. Vue d'ensemble
+
+`oc-discovery` est un service de découverte P2P pour le réseau OpenCloud. Il repose sur
+**libp2p** (transport TCP + PSK réseau privé) et une **DHT Kademlia** (préfixe `oc`)
+pour indexer les pairs. L'architecture est intentionnellement hiérarchique : des _natifs_
+stables servent de hubs autoritaires auxquels des _indexeurs_ s'enregistrent, et des _nœuds_
+ordinaires découvrent des indexeurs via ces natifs.

+```
+
+Tous les participants partagent une **clé pré-partagée (PSK)** qui isole le réseau
+des connexions libp2p externes non autorisées.
+
+---
+
+## 2. Hiérarchie des rôles
+
+| Rôle | Binaire | Responsabilité |
+|---|---|---|
+| **Node** | `node_mode=node` | Se fait indexer, publie/consulte des records DHT |
+| **Indexer** | `node_mode=indexer` | Reçoit les heartbeats, écrit en DHT, s'enregistre auprès des natifs |
+| **Native Indexer** | `node_mode=native` | Hub : tient le registre des indexeurs vivants, évalue le consensus, sert de fallback |
+
+Un même processus peut cumuler les rôles node+indexer ou indexer+native.
+
+---
+
+## 3. Mécanismes principaux
+
+### 3.1 Heartbeat long-lived (node → indexer)
+
+**Fonctionnement**
+
+Un stream libp2p **persistant** (`/opencloud/heartbeat/1.0`) est ouvert depuis le nœud
+vers chaque indexeur de son pool (`StaticIndexers`). Toutes les 20 secondes, le nœud
+envoie un `Heartbeat` JSON sur ce stream. L'indexeur répond en enregistrant le peer dans
+`StreamRecords[ProtocolHeartbeat]` avec une expiry de 2 min.
+
+Si `sendHeartbeat` échoue (stream reset, EOF, timeout), le peer est retiré de
+`StaticIndexers` et `replenishIndexersFromNative` est déclenché.
+
+**Avantages**
+- Détection rapide de déconnexion (erreur sur le prochain encode).
+- Un seul stream par pair réduit la pression sur les connexions TCP.
+- Le channel de nudge (`indexerHeartbeatNudge`) permet un reconnect immédiat sans
+  attendre le ticker de 20 s.
+
+**Limites / risques**
+- ⚠️ Un seul stream persistant : si la couche TCP reste ouverte mais "gelée" (middlebox,
+  NAT silencieux), l'erreur peut ne pas remonter avant plusieurs minutes.
+- ⚠️ `StaticIndexers` est une map partagée globale : si deux goroutines appellent
+  `replenishIndexersFromNative` simultanément (cas de perte multiple), on peut avoir
+  des écritures concurrentes non protégées hors des sections critiques.
+
+---
+
+### 3.2 Scoring de confiance
+
+**Fonctionnement**
+
+Avant d'enregistrer un heartbeat dans `StreamRecords`, l'indexeur vérifie un **score
+minimum** calculé par `CheckHeartbeat` :
+
+```
+Score = (0.4 × uptime_ratio + 0.4 × bpms + 0.2 × diversity) × 100
+```
+
+- `uptime_ratio` : durée de présence du peer / durée depuis le démarrage de l'indexeur.
+- `bpms` : débit mesuré via un stream dédié (`/opencloud/probe/1.0`) normalisé par 50 Mbps.
+- `diversity` : ratio d'IP /24 distincts parmi les indexeurs que le peer déclare.
+
+Deux seuils sont appliqués selon l'état du peer :
+- **Premier heartbeat** (peer absent de `StreamRecords`, uptime = 0) : seuil à **40**.
+- **Heartbeats suivants** (uptime accumulé) : seuil à **75**.
+
+**Avantages**
+- Décourage les peers éphémères ou lents d'encombrer le registre.
+- La diversité réseau réduit le risque de concentration sur un seul sous-réseau.
+- Le stream de probe dédié évite de polluer le stream JSON heartbeat avec des données binaires.
+- Le double seuil permet aux nouveaux peers d'être admis dès leur première connexion.
+
+**Limites / risques**
+- ✅ **Deadlock logique de démarrage corrigé** : avec uptime = 0 le score maximal était 60,
+  en-dessous du seuil de 75. Les nouveaux peers étaient silencieusement rejetés à jamais.
+  → Seuil abaissé à **40** pour le premier heartbeat (`isFirstHeartbeat`), 75 ensuite.
+- ⚠️ Les seuils (40 / 75) restent câblés en dur, sans possibilité de configuration.
+- ⚠️ La mesure de bande passante envoie entre 512 et 2048 octets par heartbeat : à 20 s
+  d'intervalle et 500 nœuds max, cela représente ~50 KB/s de trafic probe en continu.
+- ⚠️ `diversity` est calculé sur les adresses que le nœud *déclare* avoir — ce champ est
+  auto-rapporté et non vérifié, facilement falsifiable.
+
+---
+
+### 3.3 Enregistrement auprès des natifs (indexer → native)
+
+**Fonctionnement**
+
+Chaque indexeur (non-natif) envoie périodiquement (toutes les 60 s) une
+`IndexerRegistration` JSON sur un stream one-shot (`/opencloud/native/subscribe/1.0`)
+vers chaque natif configuré. Le natif :
+
+1. Stocke l'entrée en cache local avec un TTL de **90 s** (`IndexerTTL`).
+2. Gossipe le `PeerID` sur le topic PubSub `oc-indexer-registry` aux autres natifs.
+3. Persiste l'entrée en DHT de manière asynchrone (retry jusqu'à succès).
+
+**Avantages**
+- Stream jetable : pas de ressource longue durée côté natif pour les enregistrements.
+- Le cache local est immédiatement disponible pour `handleNativeGetIndexers` sans
+  attendre la DHT.
+- La dissémination PubSub permet à d'autres natifs de connaître l'indexeur sans
+  qu'il ait besoin de s'y enregistrer directement.
+
+**Limites / risques**
+- ✅ **TTL trop serré corrigé** : le TTL de 66 s n'était que 10 % au-dessus de l'intervalle
+  de 60 s — un léger retard réseau pouvait expirer un indexeur sain entre deux renewals.
+  → `IndexerTTL` porté à **90 s** (+50 %).
+- ⚠️ Si le `PutValue` DHT échoue définitivement (réseau partitionné), le natif possède
+  l'entrée mais les autres natifs qui n'ont pas reçu le message PubSub ne la connaissent
+  jamais — incohérence silencieuse.
+- ⚠️ `RegisterWithNative` ignore les adresses en `127.0.0.1`, mais ne gère pas
+  les adresses privées (RFC1918) qui seraient non routables depuis d'autres hôtes.
+
+---
+
+### 3.4 Pool d'indexeurs : fetch + consensus
+
+**Fonctionnement**
+
+Lors de `ConnectToNatives` (démarrage ou replenish), le nœud/indexeur :
+
+1. **Fetch** : envoie `GetIndexersRequest` au premier natif répondant
+   (`/opencloud/native/indexers/1.0`), reçoit une liste de candidats.
+2. **Consensus (round 1)** : interroge **tous** les natifs configurés en parallèle
+   (`/opencloud/native/consensus/1.0`, timeout 3 s, collecte sur 4 s).
+   Un indexeur est confirmé si **strictement plus de 50 %** des natifs répondants
+   le considèrent vivant.
+3. **Consensus (round 2)** : si le pool est insuffisant, les suggestions des natifs
+   (indexeurs qu'ils connaissent mais qui n'étaient pas dans les candidats initiaux)
+   sont soumises à un second round.
+
+**Avantages**
+- La règle de majorité absolue empêche un natif compromis ou désynchronisé d'injecter
+  des indexeurs fantômes.
+- Le double round permet de compléter le pool avec des alternatives connues des natifs
+  sans sacrifier la vérification.
+- Si le fetch retourne un **fallback** (natif comme indexeur), le consensus est skippé —
+  cohérent car il n'y a qu'une seule source.
+
+**Limites / risques**
+- ⚠️ Avec **un seul natif** configuré (très courant en dev/test), le consensus est trivial
+  (100 % d'un seul vote) — la règle de majorité ne protège rien dans ce cas.
+- ⚠️ `fetchIndexersFromNative` s'arrête au **premier natif répondant** (séquentiellement) :
+  si ce natif a un cache périmé ou partiel, le nœud obtient un pool sous-optimal sans
+  consulter les autres.
+- ⚠️ Le timeout de collecte global (4 s) est fixe : sur un réseau lent ou géographiquement
+  distribué, des natifs valides peuvent être éliminés faute de réponse à temps.
+- ⚠️ `replaceStaticIndexers` **ajoute** sans jamais retirer d'anciens indexeurs expirés :
+  le pool peut accumuler des entrées mortes que seul le heartbeat purge ensuite.
+
+---
+
+### 3.5 Self-delegation et offload loop
+
+**Fonctionnement**
+
+Si un natif ne dispose d'aucun indexeur vivant lors d'un `handleNativeGetIndexers`,
+il se désigne lui-même comme indexeur temporaire (`selfDelegate`) : il retourne sa propre
+adresse multiaddr et ajoute le demandeur dans `responsiblePeers`, dans la limite de
+`maxFallbackPeers` (50). Au-delà, la délégation est refusée et une réponse vide est
+retournée pour que le nœud tente un autre natif.
+
+Toutes les 30 s, `runOffloadLoop` vérifie si des indexeurs réels sont de nouveau
+disponibles. Si oui, pour chaque peer responsable :
+- **Stream présent** : `Reset()` du stream heartbeat — le peer reçoit une erreur,
+  déclenche `replenishIndexersFromNative` et migre vers de vrais indexeurs.
+- **Stream absent** (peer jamais admis par le scoring) : `ClosePeer()` sur la connexion
+  réseau — le peer reconnecte et re-demande ses indexeurs au natif.
+
+**Avantages**
+- Continuité de service : un nœud n'est jamais bloqué en l'absence temporaire d'indexeurs.
+- La migration est automatique et transparente pour le nœud.
+- `Reset()` (vs `Close()`) interrompt les deux sens du stream, garantissant que le peer
+  reçoit bien une erreur.
+- La limite de 50 empêche le natif de se retrouver surchargé lors de pénuries prolongées.
+
+**Limites / risques**
+- ✅ **Offload sans stream corrigé** : si le heartbeat n'avait jamais été enregistré dans
+  `StreamRecords` (score < seuil — cas amplifié par le bug de scoring), l'offload
+  échouait silencieusement et le peer restait dans `responsiblePeers` indéfiniment.
+  → Branche `else` : `ClosePeer()` + suppression de `responsiblePeers`.
+- ✅ **`responsiblePeers` illimité corrigé** : le natif acceptait un nombre arbitraire
+  de peers en self-delegation, devenant lui-même un indexeur surchargé.
+  → `selfDelegate` vérifie `len(responsiblePeers) >= maxFallbackPeers` et retourne
+  `false` si saturé.
+- ⚠️ La délégation reste non coordonnée entre natifs : un natif surchargé refuse (retourne
+  vide) mais ne redirige pas explicitement vers un natif voisin qui aurait de la capacité.
+
+---
+
+### 3.6 Résilience du mesh natif
+
+**Fonctionnement**
+
+Quand le heartbeat vers un natif échoue, `replenishNativesFromPeers` tente de trouver
+un remplaçant dans cet ordre :
+
+1. `fetchNativeFromNatives` : demande à chaque natif vivant (`/opencloud/native/peers/1.0`)
+   une adresse de natif inconnue.
+2. `fetchNativeFromIndexers` : demande à chaque indexeur connu
+   (`/opencloud/indexer/natives/1.0`) ses natifs configurés.
+3. Si aucun remplaçant et `remaining ≤ 1` : `retryLostNative` relance un ticker de 30 s
+   qui retente la connexion directe au natif perdu.
+
+`EnsureNativePeers` maintient des heartbeats de natif à natif via `ProtocolHeartbeat`,
+avec une **unique goroutine** couvrant toute la map `StaticNatives`.
+
+**Avantages**
+- Le gossip multi-hop via indexeurs permet de retrouver un natif même si aucun pair
+  direct ne le connaît.
+- `retryLostNative` gère le cas d'un seul natif (déploiement minimal).
+- La reconnexion automatique (`retryLostNative`) déclenche `replenishIndexersIfNeeded`
+  pour restaurer aussi le pool d'indexeurs.
+
+**Limites / risques**
+- ✅ **Goroutines heartbeat multiples corrigé** : `EnsureNativePeers` démarrait une
+  goroutine `SendHeartbeat` par adresse native (N natifs → N goroutines → N² heartbeats
+  par tick). → Utilisation de `nativeMeshHeartbeatOnce` : une seule goroutine itère sur
+  `StaticNatives`.
+- ⚠️ `retryLostNative` tourne indéfiniment sans condition d'arrêt liée à la vie du processus
+  (pas de `context.Context`). Si le binaire est gracefully shutdown, cette goroutine
+  peut bloquer.
+- ⚠️ La découverte transitoire (natif → indexeur → natif) est à sens unique : un indexeur
+  ne connaît que les natifs de sa propre config, pas les nouveaux natifs qui auraient
+  rejoint après son démarrage.
+
+---
+
+### 3.7 DHT partagée
+
+**Fonctionnement**
+
+Tous les indexeurs et natifs participent à une DHT Kademlia (préfixe `oc`, mode
+`ModeServer`). Deux namespaces sont utilisés :
+
+- `/node/<DID>` → `PeerRecord` JSON signé (publié par les indexeurs sur heartbeat de nœud).
+- `/indexer/<PeerID>` → `liveIndexerEntry` JSON avec TTL (publié par les natifs).
+
+Chaque natif lance `refreshIndexersFromDHT` (toutes les 30 s) qui ré-hydrate son cache
+local depuis la DHT pour les PeerIDs connus (`knownPeerIDs`) dont l'entrée locale a expiré.
+
+**Avantages**
+- Persistance décentralisée : un record survit à la perte d'un seul natif ou indexeur.
+- Validation des entrées : `PeerRecordValidator` et `IndexerRecordValidator` rejettent
+  les records malformés ou expirés au moment du `PutValue`.
+- L'index secondaire `/name/<name>` permet la résolution par nom humain.
+
+**Limites / risques**
+- ⚠️ La DHT Kademlia en réseau privé (PSK) est fonctionnelle mais les nœuds bootstrap
+  ne sont pas configurés explicitement : la découverte dépend de connexions déjà établies,
+  ce qui peut ralentir la convergence au démarrage.
+- ⚠️ `PutValue` est réessayé en boucle infinie si `"failed to find any peer in table"` —
+  une panne de réseau prolongée génère des goroutines bloquées.
+- ⚠️ Si la PSK est compromise, un attaquant peut écrire dans la DHT ; les `liveIndexerEntry`
+  d'indexeurs ne sont pas signées, contrairement aux `PeerRecord`.
+- ⚠️ `refreshIndexersFromDHT` prune `knownPeerIDs` si la DHT n'a aucune entrée fraîche,
+  mais ne prune pas `liveIndexers` — une entrée expirée reste en mémoire jusqu'au GC
+  ou au prochain refresh.
+
+---
+
+### 3.8 PubSub gossip (indexer registry)
+
+**Fonctionnement**
+
+Quand un indexeur s'enregistre auprès d'un natif, ce dernier publie l'adresse sur le
+topic GossipSub `oc-indexer-registry`. Les autres natifs abonnés mettent à jour leur
+`knownPeerIDs` sans attendre la DHT.
+
+Le `TopicValidator` rejette tout message dont le contenu n'est pas un multiaddr
+parseable valide avant qu'il n'atteigne la boucle de traitement.
+
+**Avantages**
+- Dissémination quasi-instantanée entre natifs connectés.
+- Complément utile à la DHT pour les registrations récentes qui n'ont pas encore
+  été persistées.
+- Le filtre syntaxique bloque les messages malformés avant propagation dans le mesh.
+
+**Limites / risques**
+- ✅ **`TopicValidator` sans validation corrigé** : le validateur acceptait systématiquement
+  tous les messages (`return true`), permettant à un natif compromis de gossiper
+  n'importe quelle donnée.
+  → Le validateur vérifie désormais que le message est un multiaddr parseable
+  (`pp.AddrInfoFromString`).
+- ⚠️ La validation reste syntaxique uniquement : l'origine du message (l'émetteur
+  est-il un natif légitime ?) n'est pas vérifiée.
+- ⚠️ Si le natif redémarre, il perd son abonnement et manque les messages publiés
+  pendant son absence. La re-hydratation depuis la DHT compense, mais avec un délai
+  pouvant aller jusqu'à 30 s.
+- ⚠️ Le gossip ne porte que le `Addr` de l'indexeur, pas sa TTL ni sa signature.
+
+---
+
+### 3.9 Streams applicatifs (node ↔ node)
+
+**Fonctionnement**
+
+`StreamService` gère les streams entre nœuds partenaires (relations `PARTNER` stockées
+en base) via des protocols dédiés (`/opencloud/resource/*`). Un heartbeat partenaire
+(`ProtocolHeartbeatPartner`) maintient les connexions actives. Les events sont routés
+via `handleEvent` et le système NATS en parallèle.
+
+**Avantages**
+- TTL par protocol (`PersistantStream`, `WaitResponse`) adapte le comportement au
+  type d'échange (longue durée pour le planner, courte pour les CRUDs).
+- La GC (`gc()` toutes les 8 s, démarrée une seule fois dans `InitStream`) libère
+  rapidement les streams expirés.
+
+**Limites / risques**
+- ✅ **Fuite de goroutines GC corrigée** : `HandlePartnerHeartbeat` appelait
+  `go s.StartGC(30s)` à chaque heartbeat reçu (~20 s), créant un nouveau ticker
+  goroutine infini à chaque appel.
+  → Appel supprimé ; la GC lancée par `InitStream` est suffisante.
+- ✅ **Boucle infinie sur EOF corrigée** : `readLoop` effectuait `s.Stream.Close();
+  continue` après une erreur de décodage, re-tentant indéfiniment de lire un stream
+  fermé.
+  → Remplacé par `return` ; les defers (`Close`, `delete`) nettoient correctement.
+- ⚠️ La récupération de partenaires depuis `conf.PeerIDS` est marquée `TO REMOVE` :
+  présence de code provisoire en production.
+
+---
+
+## 4. Tableau récapitulatif
+
+| Mécanisme | Protocole | Avantage principal | État du risque |
+|---|---|---|---|
+| Heartbeat node→indexer | `/opencloud/heartbeat/1.0` | Détection rapide de perte | ⚠️ Stream TCP gelé non détecté |
+| Scoring de confiance | (inline dans heartbeat) | Filtre les pairs instables | ✅ Deadlock corrigé (seuil 40/75) |
+| Enregistrement natif | `/opencloud/native/subscribe/1.0` | TTL ample, cache immédiat | ✅ TTL porté à 90 s |
+| Fetch pool d'indexeurs | `/opencloud/native/indexers/1.0` | Prend le 1er natif répondant | ⚠️ Natif au cache périmé possible |
+| Consensus | `/opencloud/native/consensus/1.0` | Majorité absolue | ⚠️ Trivial avec 1 seul natif |
+| Self-delegation + offload | (in-memory) | Disponibilité sans indexeur | ✅ Limite 50 peers + ClosePeer |
+| Mesh natif | `/opencloud/native/peers/1.0` | Gossip multi-hop | ✅ Goroutines dédupliquées |
+| DHT | `/oc/kad/1.0.0` | Persistance décentralisée | ⚠️ Retry infini, pas de bootstrap |
+| PubSub registry | `oc-indexer-registry` | Dissémination rapide | ✅ Validation multiaddr |
+| Streams applicatifs | `/opencloud/resource/*` | TTL par protocol | ✅ Fuite GC + EOF corrigés |
+
+---
+
+## 5. Risques et limites globaux
+
+### Sécurité
+
+- ⚠️ **Adresses auto-rapportées non vérifiées** : le champ `IndexersBinded` dans le heartbeat
+  est auto-déclaré par le nœud et sert à calculer la diversité. Un pair malveillant peut
+  gonfler son score en déclarant de fausses adresses.
+- ⚠️ **PSK comme seule barrière d'entrée** : si la PSK est compromise (elle est statique et
+  fichier-based), tout l'isolement réseau saute. Il n'y a pas de rotation de clé ni
+  d'authentification supplémentaire par pair.
+- ⚠️ **DHT sans ACL sur les entrées indexeur** : la signature des `PeerRecord` est vérifiée
+  à la lecture, mais les `liveIndexerEntry` ne sont pas signées. La validation PubSub
+  bloque les multiaddrs invalides mais pas les adresses d'indexeurs légitimes usurpées.
+
+### Disponibilité
+
+- ⚠️ **Single point of failure natif** : avec un seul natif, la perte de celui-ci stoppe
+  toute attribution d'indexeurs. `retryLostNative` pallie, mais sans indexeurs, les nœuds
+  ne peuvent pas publier.
+- ⚠️ **Bootstrap DHT** : sans nœuds bootstrap explicites, la DHT met du temps à converger
+  si les connexions initiales sont peu nombreuses.
+
+### Cohérence
+
+- ⚠️ **`replaceStaticIndexers` n'efface jamais** : d'anciens indexeurs morts restent dans
+  `StaticIndexers` jusqu'à ce que le heartbeat échoue. Un nœud peut avoir un pool
+  surévalué contenant des entrées inatteignables.
+- ⚠️ **`TimeWatcher` global** : défini une seule fois au démarrage de `ConnectToIndexers`.
+  Si l'indexeur tourne depuis longtemps, les nouveaux nœuds auront un `uptime_ratio`
+  durablement faible. Le seuil abaissé à 40 pour le premier heartbeat atténue l'impact
+  initial, mais les heartbeats suivants devront accumuler un uptime suffisant.
+
+---
+
+## 6. Pistes d'amélioration
+
+Les pistes déjà implémentées sont marquées ✅. Les pistes ouvertes restent à traiter.
+
+### ✅ Score : double seuil pour les nouveaux peers
+~~Remplacer le seuil binaire~~ — **Implémenté** : seuil à 40 pour le premier heartbeat
+(peer absent de `StreamRecords`), 75 pour les suivants. Un peer peut désormais être admis
+dès sa première connexion sans bloquer sur l'uptime nul.
+_Fichier : `common/common_stream.go`, `CheckHeartbeat`_
+
+### ✅ TTL indexeur aligné avec l'intervalle de renouvellement
+~~TTL de 66 s trop proche de 60 s~~ — **Implémenté** : `IndexerTTL` passé à **90 s**.
+_Fichier : `indexer/native.go`_
+
+### ✅ Limite de la self-delegation
+~~`responsiblePeers` illimité~~ — **Implémenté** : `selfDelegate` retourne `false` quand
+`len(responsiblePeers) >= maxFallbackPeers` (50). Le site d'appel retourne une réponse
+vide et logue un warning.
+_Fichier : `indexer/native.go`_
+
+### ✅ Validation PubSub des adresses gossipées
+~~`TopicValidator` accepte tout~~ — **Implémenté** : le validateur vérifie que le message
+est un multiaddr parseable via `pp.AddrInfoFromString`.
+_Fichier : `indexer/native.go`, `subscribeIndexerRegistry`_
+
+### ✅ Goroutines heartbeat dédupliquées dans `EnsureNativePeers`
+~~Une goroutine par adresse native~~ — **Implémenté** : `nativeMeshHeartbeatOnce`
+garantit qu'une seule goroutine `SendHeartbeat` couvre toute la map `StaticNatives`.
+_Fichier : `common/native_stream.go`_
+
+### ✅ Fuite de goroutines GC dans `HandlePartnerHeartbeat`
+~~`go s.StartGC(30s)` à chaque heartbeat~~ — **Implémenté** : appel supprimé ; la GC
+de `InitStream` est suffisante.
+_Fichier : `stream/service.go`_
+
+### ✅ Boucle infinie sur EOF dans `readLoop`
+~~`continue` après `Stream.Close()`~~ — **Implémenté** : remplacé par `return` pour
+laisser les defers nettoyer proprement.
+_Fichier : `stream/service.go`_
+
+---
+
+### ⚠️ Fetch pool : interroger tous les natifs en parallèle
+
+`fetchIndexersFromNative` s'arrête au premier natif répondant. Interroger tous les natifs
+en parallèle et fusionner les listes (similairement à `clientSideConsensus`) éviterait
+qu'un natif au cache périmé fournisse un pool sous-optimal.
+
+### ⚠️ Consensus avec quorum configurable
+
+Le seuil de confirmation (`count*2 > total`) est câblé en dur. Le rendre configurable
+(ex. `consensus_quorum: 0.67`) permettrait de durcir la règle sur des déploiements
+à 3+ natifs sans modifier le code.
+
+### ⚠️ Désenregistrement explicite
+
+Ajouter un protocole `/opencloud/native/unsubscribe/1.0` : quand un indexeur s'arrête
+proprement, il notifie les natifs pour invalider son TTL immédiatement plutôt qu'attendre
+90 s.
+
+### ⚠️ Bootstrap DHT explicite
+
+Configurer les natifs comme nœuds bootstrap DHT via `dht.BootstrapPeers` pour accélérer
+la convergence Kademlia au démarrage.
+
+### ⚠️ Context propagé dans les goroutines longue durée
+
+`retryLostNative`, `refreshIndexersFromDHT` et `runOffloadLoop` ne reçoivent aucun
+`context.Context`. Les passer depuis `InitNative` permettrait un arrêt propre lors du
+shutdown du processus.
+
+### ⚠️ Redirection explicite lors du refus de self-delegation
+
+Quand un natif refuse la self-delegation (pool saturé), retourner vide force le nœud à
+réessayer sans lui indiquer vers qui se tourner. Une liste de natifs alternatifs dans la
+réponse (`AlternativeNatives []string`) permettrait au nœud de trouver directement un
+natif moins chargé.

+# GNU AFFERO GENERAL PUBLIC LICENSE
+
+Version 3, 19 November 2007
+
+Copyright (C) 2007 Free Software Foundation, Inc.
+<https://fsf.org/>
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+## Preamble
+
+The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains
+free software for all its users.
+
+When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate. Many developers of free software are heartened and
+encouraged by the resulting cooperation. However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community. It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server. Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals. This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing
+under this license.
+
+The precise terms and conditions for copying, distribution and
+modification follow.
+
+## TERMS AND CONDITIONS
+
+### 0. Definitions.
+
+"This License" refers to version 3 of the GNU Affero General Public
+License.
+
+"Copyright" also means copyright-like laws that apply to other kinds
+of works, such as semiconductor masks.
+
+"The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of
+an exact copy. The resulting work is called a "modified version" of
+the earlier work or a work "based on" the earlier work.
+
+A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user
+through a computer network, with no transfer of a copy, is not
+conveying.
+
+An interactive user interface displays "Appropriate Legal Notices" to
+the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+### 1. Source Code.
+
+The "source code" for a work means the preferred form of the work for
+making modifications to it. "Object code" means any non-source form of
+a work.
+
+A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+The Corresponding Source need not include anything that users can
+regenerate automatically from other parts of the Corresponding Source.
+
+The Corresponding Source for a work in source code form is that same
+work.
+
+### 2. Basic Permissions.
+
+All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+You may make, run and propagate covered works that you do not convey,
+without conditions so long as your license otherwise remains in force.
+You may convey covered works to others for the sole purpose of having
+them make modifications exclusively for you, or provide you with
+facilities for running those works, provided that you comply with the
+terms of this License in conveying all material for which you do not
+control copyright. Those thus making or running the covered works for
+you must do so exclusively on your behalf, under your direction and
+control, on terms that prohibit them from making any copies of your
+copyrighted material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the
+conditions stated below. Sublicensing is not allowed; section 10 makes
+it unnecessary.
+
+### 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such
+circumvention is effected by exercising rights under this License with
+respect to the covered work, and you disclaim any intention to limit
+operation or modification of the work as a means of enforcing, against
+the work's users, your or third parties' legal rights to forbid
+circumvention of technological measures.
+
+### 4. Conveying Verbatim Copies.
+
+You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+### 5. Conveying Modified Source Versions.
+
+You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these
+conditions:
+
+-   a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+-   b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under
+    section 7. This requirement modifies the requirement in section 4
+    to "keep intact all notices".
+-   c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy. This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged. This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+-   d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+### 6. Conveying Non-Source Forms.
+
+You may convey a covered work in object code form under the terms of
+sections 4 and 5, provided that you also convey the machine-readable
+Corresponding Source under the terms of this License, in one of these
+ways:
+
+-   a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+-   b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the Corresponding
+    Source from a network server at no charge.
+-   c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source. This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+-   d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge. You need not require recipients to copy the
+    Corresponding Source along with the object code. If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source. Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+-   e) Convey the object code using peer-to-peer transmission,
+    provided you inform other peers where the object code and
+    Corresponding Source of the work are being offered to the general
+    public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal,
+family, or household purposes, or (2) anything designed or sold for
+incorporation into a dwelling. In determining whether a product is a
+consumer product, doubtful cases shall be resolved in favor of
+coverage. For a particular product received by a particular user,
+"normally used" refers to a typical or common use of that class of
+product, regardless of the status of the particular user or of the way
+in which the particular user actually uses, or expects or is expected
+to use, the product. A product is a consumer product regardless of
+whether the product has substantial commercial, industrial or
+non-consumer uses, unless such uses represent the only significant
+mode of use of the product.
+
+"Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to
+install and execute modified versions of a covered work in that User
+Product from a modified version of its Corresponding Source. The
+information must suffice to ensure that the continued functioning of
+the modified object code is in no case prevented or interfered with
+solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or
+updates for a work that has been modified or installed by the
+recipient, or for the User Product in which it has been modified or
+installed. Access to a network may be denied when the modification
+itself materially and adversely affects the operation of the network
+or violates the rules and protocols for communication across the
+network.
+
+Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+### 7. Additional Terms.
+
+"Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders
+of that material) supplement the terms of this License with terms:
+
+-   a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+-   b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+-   c) Prohibiting misrepresentation of the origin of that material,
+    or requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+-   d) Limiting the use for publicity purposes of names of licensors
+    or authors of the material; or
+-   e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+-   f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions
+    of it) with contractual assumptions of liability to the recipient,
+    for any liability that these contractual assumptions directly
+    impose on those licensors and authors.
+
+All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions; the
+above requirements apply either way.
+
+### 8. Termination.
+
+You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+### 9. Acceptance Not Required for Having Copies.
+
+You are not required to accept this License in order to receive or run
+a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+### 10. Automatic Licensing of Downstream Recipients.
+
+Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+### 11. Patents.
+
+A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+A contributor's "essential patent claims" are all patent claims owned
+or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+A patent license is "discriminatory" if it does not include within the
+scope of its coverage, prohibits the exercise of, or is conditioned on
+the non-exercise of one or more of the rights that are specifically
+granted under this License. You may not convey a covered work if you
+are a party to an arrangement with a third party that is in the
+business of distributing software, under which you make payment to the
+third party based on the extent of your activity of conveying the
+work, and under which the third party grants, to any of the parties
+who would receive the covered work from you, a discriminatory patent
+license (a) in connection with copies of the covered work conveyed by
+you (or copies made from those copies), or (b) primarily for and in
+connection with specific products or compilations that contain the
+covered work, unless you entered into that arrangement, or that patent
+license was granted, prior to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+### 12. No Surrender of Others' Freedom.
+
+If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under
+this License and any other pertinent obligations, then as a
+consequence you may not convey it at all. For example, if you agree to
+terms that obligate you to collect a royalty for further conveying
+from those to whom you convey the Program, the only way you could
+satisfy both those terms and this License would be to refrain entirely
+from conveying the Program.
+
+### 13. Remote Network Interaction; Use with the GNU General Public License.
+
+Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your
+version supports such interaction) an opportunity to receive the
+Corresponding Source of your version by providing access to the
+Corresponding Source from a network server at no charge, through some
+standard or customary means of facilitating copying of software. This
+Corresponding Source shall include the Corresponding Source for any
+work covered by version 3 of the GNU General Public License that is
+incorporated pursuant to the following paragraph.
+
+Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+### 14. Revised Versions of this License.
+
+The Free Software Foundation may publish revised and/or new versions
+of the GNU Affero General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever
+published by the Free Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions
+of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+### 15. Disclaimer of Warranty.
+
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT
+WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
+LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
+A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
+PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
+DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
+CORRECTION.
+
+### 16. Limitation of Liability.
+
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR
+CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
+ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
+NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
+LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM
+TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
+PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+### 17. Interpretation of Sections 15 and 16.
+
+If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+END OF TERMS AND CONDITIONS
+
+## How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these
+terms.
+
+To do so, attach the following notices to the program. It is safest to
+attach them to the start of each source file to most effectively state
+the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+        <one line to give the program's name and a brief idea of what it does.>
+        Copyright (C) <year>  <name of author>
+
+        This program is free software: you can redistribute it and/or modify
+        it under the terms of the GNU Affero General Public License as
+        published by the Free Software Foundation, either version 3 of the
+        License, or (at your option) any later version.
+
+        This program is distributed in the hope that it will be useful,
+        but WITHOUT ANY WARRANTY; without even the implied warranty of
+        MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+        GNU Affero General Public License for more details.
+
+        You should have received a copy of the GNU Affero General Public License
+        along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper
+mail.
+
+If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source. For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code. There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for
+the specific requirements.
+
+You should also get your employer (if you work as a programmer) or
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. For more information on this, and how to apply and follow
+the GNU AGPL, see <https://www.gnu.org/licenses/>.
