feat(netcode): chiffrement AES-256-ECB conforme FAESHandlerComponent d'UE

Recycle a confirmé : 'basic aes', clé server-side déductible client, by-the-book reimpl,
pas de handshake DTLS. Remplace le GCM par AES-256-ECB + PKCS#7 + flag bit + termination
bit (mirror du source UE 4.27). Flux : SetKey -> EncryptionAck clair -> Enable -> Challenge
chiffré. Supprime AesGcmHandlerComponent.

+# 🎮 The Cycle: Frontier — Rejoindre le serveur privé (installation client)
+
+Guide pour **installer le client et jouer sur le serveur privé**. Tu n'installes **rien côté serveur** — juste le jeu + un loader + un certificat.
+
+> ⚠️ **À savoir avant de commencer**
+> - Le jeu a été retiré de Steam en septembre 2022 : il faut **l'avoir déjà eu dans ta bibliothèque Steam** pour le retélécharger.
+> - **Ce n'est pas du co-op en raid.** Chacun joue sa propre instance (stations solo) ; l'émulateur ne supporte pas plusieurs joueurs dans le même raid. Vous partagez le même serveur (progression, boutiques, comptes), pas la même partie.
+> - Le serveur doit être **allumé** au moment où tu joues (demande à l'hébergeur).
+
+---
+
+## Fichiers à télécharger (dans la release)
+Les 2 fichiers sont dispo dans la **release Gitea** :
+👉 **https://git.nfteam.ovh/neckfire/the-cycle/releases/tag/friends-client**
+
+1. **`LoaderPack.zip`** — le loader qui redirige le jeu vers le serveur privé (build b8 / Saison 2).
+2. **`certificate.crt`** — le certificat **public** du serveur (sans clé privée, safe).
+
+Télécharge les deux depuis la page de release avant de commencer.
+
+---
+
+## Étapes (Windows)
+
+### 1. Installer le client Saison 2 (via la console Steam)
+1. Steam ouvert, `Win+R` → tape `steam://nav/console` → Entrée (la **console Steam** s'ouvre).
+2. Colle **exactement** cette commande → Entrée :
+   ```
+   download_depot 868270 868271 4623363103423775682
+   ```
+   (`868270` = le jeu, `868271` = le dépôt client, `4623363103423775682` = manifest **Saison 2 v2.7.2**.)
+3. Le téléchargement démarre (⚠️ **pas de barre de progression**, sois patient — plusieurs Go).
+4. À la fin, Steam affiche **« Depot download complete »** + le **chemin du dossier**
+   (ex. `...\Steam\steamapps\content\app_868270\depot_868271`). **Ce dossier = ton install du jeu.**
+
+> Il faut **avoir eu The Cycle: Frontier dans ta bibliothèque Steam** avant, sinon → erreur `missing license`.
+
+> **Pas assez d'espace sur le disque principal ?** `download_depot` écrit toujours dans `...\Steam\steamapps\content`. Pour le mettre sur un autre disque : ferme Steam, supprime `...\Steam\steamapps\content`, puis en **cmd admin** :
+> ```
+> mkdir "D:\SteamContent"
+> mklink /J "C:\Program Files (x86)\Steam\steamapps\content" "D:\SteamContent"
+> ```
+> Rouvre Steam et relance la commande → le jeu ira sur `D:\`.
+
+### 2. Installer le LoaderPack
+1. Va dans le dossier du jeu → **`Prospect\Binaries\Win64`**.
+2. Ouvre `LoaderPack.zip` et **glisse tout son contenu** dans ce dossier `Win64`.
+3. Crée un **raccourci** vers `Prospect.Client.Loader.exe` (c'est avec ça que tu lanceras le jeu).
+
+### 3. Faire confiance au certificat du serveur
+1. Double-clique **`certificate.crt`** → **Installer le certificat**.
+2. **Emplacement : Utilisateur actuel** → Suivant.
+3. **Placer tous les certificats dans le magasin suivant** → **Parcourir** → **Autorités de certification racines de confiance** → OK → Suivant → Terminer.
+4. Accepte l'avertissement de sécurité (il mentionne `2EA46.playfabapi.com`).
+
+### 4. Pointer le client vers le serveur
+Dans **`Prospect\Binaries\Win64`**, crée (ou édite) un fichier **`backend.txt`** contenant **exactement** cette ligne :
+
+```
+https://tc.nfteam.ovh:8443
+```
+
+### 5. Lancer le jeu
+1. **Steam doit être ouvert** (connecté à ton compte).
+2. Lance le jeu via le **raccourci `Prospect.Client.Loader`** (⚠️ pas via Steam directement).
+3. Connexion automatique avec ton compte Steam. Bienvenue sur Fortuna III ! 🚀
+
+---
+
+## Dépannage
+| Symptôme | Cause / solution |
+|---|---|
+| `libcurl error 7 (Couldn't connect to server)` | Le serveur est **éteint** → demande à l'hébergeur de l'allumer. |
+| Erreur de certificat / `hostname mismatch` | `certificate.crt` **pas importé** (ou pas dans « Autorités racines de confiance »). Refais l'étape 3. |
+| `missing license` au téléchargement | Tu n'as jamais eu le jeu sur ce compte Steam → impossible de le retélécharger. |
+| Parties du corps manquantes (client S3) | Va en station → change ton apparence une fois (corrige les IDs). |

+# Serveur de jeu dédié — R&D (branche `game-server`)
+
+> ⚠️ **Expérimental.** Objectif : un serveur de jeu **autoritaire** pour que plusieurs
+> joueurs soient dans la **même instance** (se voir, bouger). C'est un chantier de
+> reverse-engineering du serveur Unreal du Cycle. **Un raid co-op complet reste hors de portée
+> réaliste** ; on avance par jalons. **IA et loot volontairement hors périmètre pour l'instant.**
+
+## Pièces en jeu
+- **`Prospect.Unreal`** — réimplémentation en C# de la couche réseau d'Unreal Engine
+  (NetDriver UDP, channels control/actor, bunches, packet handler, handshake, `UWorld`,
+  `AGameModeBase`/`APlayerController`/`APawn`).
+- **`Prospect.Server.Game`** — l'exécutable serveur (host loop, monde, game mode).
+
+## État actuel (ce qui marche côté serveur)
+Le **handshake de connexion Unreal est implémenté** et va jusqu'au spawn du PlayerController :
+
+```
+NMT_Hello  →  SendChallenge
+NMT_Login  →  PreLogin → WelcomePlayer (envoie map + game mode)
+NMT_Join   →  SpawnPlayActor → GameMode.Login → APlayerController
+```
+
+Corrections/avancées de cette branche :
+- **Cible la map/gamemode du Cycle** (`/Game/Maps/MP/Station/Station_P` + `YGameMode_Station`)
+  au lieu de la map template d'UE. Configurable via `PROSPECT_MAP` / `PROSPECT_GAMEMODE` / `PROSPECT_PORT`.
+- **`WelcomePlayer`** envoie désormais la **vraie** map/gamemode du monde (plus le template).
+- **`GameSession`** est initialisée → le login ne plante plus sur `"GameSession is null"`
+  (c'était le point de blocage juste avant le spawn).
+
+## Ce qui manque (roadmap, du plus atteignable au plus dur)
+1. **Connexion client réelle** : valider le handshake complet avec le **vrai client** (pas le
+   harnais `Client.cs`). Nécessite des **tests en live** (impossible à valider hors client).
+2. **Spawn du Pawn du Cycle** : `GameMode.Login` spawn un `APlayerController` mais **pas** le
+   personnage. Il faut spawner la **classe de Pawn spécifique du Cycle** (`YCharacter…`) avec le
+   bon **NetGUID / class path** pour que le client l'instancie.
+3. **Réplication du mouvement** : répliquer les propriétés du `CharacterMovementComponent`
+   (position/rotation/état) chaque tick → **le premier vrai « se voir bouger »**.
+4. *(plus tard)* IA, loot, dégâts, tempête, évac… — **hors périmètre pour l'instant**.
+
+Les jalons 2–3 demandent de connaître les **classes répliquées du jeu** (côté client, non
+présentes dans le code serveur) et **itèrent en live** avec le client. C'est le vrai mur.
+
+## Build / run
+```bash
+# build
+dotnet build src/Prospect.Server.Game/Prospect.Server.Game.csproj -c Release
+# run (défauts : station, port 7777 UDP)
+dotnet run --project src/Prospect.Server.Game
+# ou conteneur
+docker build -t the-cycle-game -f Dockerfile.gameserver .
+docker run --rm -p 7777:7777/udp the-cycle-game
+```
+
+## CI/CD
+`.gitea/workflows/game-server.yml` : à chaque push sur `game-server`, build de `Dockerfile.gameserver`
+→ image **`git.nfteam.ovh/neckfire/the-cycle-game`** (tags `game-server` + sha) + notif ntfy.
+Image **séparée** de l'API (`the-cycle`) — les deux ne se marchent pas dessus.
+
+## Honnêteté
+Ceci est une **base d'exploration**. Le handshake + le spawn du controller avancent ; le
+« 2 joueurs se voient bouger » dépend du spawn du pawn du Cycle + réplication, qui exige du RE
+spécifique au jeu **et** des tests dans le client réel. Aucune garantie d'aboutir.

+# The Cycle: Frontier — serveur dédié gameplay (R&D netcode)
+
+Branche `game-server`. Objectif : un serveur de jeu autoritatif écrit from scratch
+(Prospect.Unreal, réimplémentation C# du netcode Unreal) pour du vrai co-op, sans
+passer par un client-hôte P2P. **Statut : bloqué au chiffrement (voir plus bas).**
+
+Client cible : **UE4 build `R3.5.0`** (`4.27.2` netcode), Steam depot 868271.
+
+## Ce qui fonctionne (murs franchis)
+
+La connexion d'un vrai client va jusqu'à l'entrée du login :
+
+```
+Handshake stateless UDP (cookie/challenge)        ✅
+Reconstruction du paquet (PacketHandler)          ✅
+Séquençage des paquets (adopt des seq client)     ✅
+Alignement des bunches                             ✅  ← percée
+Canal de contrôle ouvert                           ✅
+NMT_Hello reçu et parsé                            ✅
+Transition login Hello → Login                     ✅
+Chiffrement DTLS-PSK                               ❌  ← mur final
+```
+
+### Percée : le bit de header spécifique R3.5.0
+
+Le client écrit **un bit de plus** entre l'historique d'ack du `FNetPacketNotify` et
+le payload packet-info, que l'UE 4.27 stock (EngineNetVer 16) n'a pas. Décodage
+bit-à-bit d'un vrai paquet : l'en-tête fait **65 bits, pas 64**. En consommant ce bit
+(`bCycleExtraHeaderBit` dans `UNetConnection.ReceivedPacket`), tout se réaligne :
+`bHasPacketInfoPayload`, l'horloge jitter (10 bits) et `bHasServerFrameTime` tombent
+juste, et le premier bunch du canal de contrôle parse proprement (ChIndex 0, bOpen,
+bReliable = NMT_Hello). Sans ce fix, le `ChIndex` sortait en vrac (~1 049 000) et le
+serveur droppait/plantait.
+
+## Le mur final : chiffrement DTLS-PSK
+
+Le client **exige** le chiffrement. Établi par reverse-engineering :
+
+- `NMT_Hello` porte `EncryptionToken` = le **PlayFab user_id** du joueur
+  (ex. `92EBCFE8C3EAF3AC`). Vu dans l'URL de connexion du client :
+  `...?EntityToken=<JWT>?EncryptionToken=92EBCFE8C3EAF3AC`.
+- Pile PacketHandler du client (ses propres logs) :
+  `[DTLSHandlerComponent, StatelessConnectHandlerComponent]`.
+- Le exe embarque les suites **`ECDHE-PSK-AES256-*`, `DHE-PSK-AES256-GCM-SHA384`**,
+  la cvar **`DTLS.PreSharedKeys`**, et `DTLSPSKClientCallback` / `DTLSPSKServerCallback`
+  → **DTLS en mode PSK** (clé pré-partagée 32 octets, identité = user_id).
+- Compression : **OodleNetwork** compilé, mais **aucun dictionnaire `.udic`** →
+  pass-through (les paquets ne sont ni compressés ni chiffrés au niveau paquet ;
+  entropie faible + longues suites de zéros le confirment).
+
+Proposer un challenge en clair (sans `NMT_EncryptionAck`) ne marche pas : le client
+ferme le canal de contrôle juste après.
+
+Pour finir il faudrait : (1) un **serveur DTLS-PSK** collé au framing du
+`DTLSHandlerComponent` d'UE, et (2) la **PSK de 32 octets** dérivée par le client à
+partir du user_id/EntityToken.
+
+## Pourquoi la clé est inaccessible (statique)
+
+L'exe `Prospect-Win64-Shipping.exe` est **packé/chiffré** (protection anti-triche,
+BattlEye) :
+
+- **Entropie de `.text` = 8.000** (maximum = aléatoire/chiffré ; du code normal ≈ 6.3).
+- `.rdata` = 4.96 (normal → les strings restent lisibles, d'où les découvertes ci-dessus).
+- Un scan brut du `.text` (76 Mo) ne trouve que **~76 instructions** → niveau du bruit :
+  ce n'est pas du code sur disque, c'est du chiffré déchiffré au runtime.
+
+Conséquence : Ghidra / radare2 n'analysent que du ciphertext ; **aucune référence** aux
+fonctions de chiffrement n'est trouvable statiquement. La dérivation de la PSK vit dans
+ce code chiffré.
+
+**Seule voie restante (non tentée)** : dump mémoire au runtime. Le jeu tourne sous
+Proton/Linux (BattlEye n'a pas de driver kernel sous Linux) → un autre process Linux
+peut lire `/proc/<pid>/mem` et récupérer le `.text` **déchiffré**, puis l'analyser dans
+Ghidra pour retrouver la dérivation. Zone grise ToS, plusieurs étapes.
+
+## Fichiers clés
+
+- `src/Prospect.Server.Game/Program.cs` — hôte du serveur de jeu (map Station, GameSession).
+- `src/Prospect.Unreal/Net/UNetConnection.cs` — `ReceivedPacket` : fix du bit de header
+  (`bCycleExtraHeaderBit`), adopt des séquences client, drop gracieux des bunches.
+- `src/Prospect.Unreal/Runtime/UWorld.cs` — `NotifyControlMessage` : Hello/Login ;
+  le `else` du bloc `NMT.Hello` documente le mur DTLS-PSK.
+
+## Verdict
+
+On a amené un serveur dédié gameplay The Cycle plus loin qu'aucun projet public connu
+(le projet communautaire deiteris/Prospect n'émule que les services en ligne, pas le
+netcode de jeu). Le mur restant — DTLS-PSK dont la clé est derrière un packer
+anti-triche — est un chantier crypto + RE dynamique d'un autre ordre de grandeur.
+
+## MAJ (2026-07-16) — mur DTLS franchi (côté serveur)
+
+- **PSK récupérée** : la clé 32 octets a été obtenue au runtime (dump du `.text`
+  déchiffré du client via `/proc/<pid>/mem` sous Proton — BattlEye n'a pas de driver
+  kernel sous Linux). Stockée dans **Vault** (`secret/the-cycle`, clé
+  `GAMESERVER_DTLS_PSKS`, format `user_id:hex32`), **jamais dans le repo**.
+- **Serveur DTLS-PSK implémenté** (BouncyCastle) :
+  - `DtlsPskStore` (env `PROSPECT_DTLS_PSKS`), `DtlsPacketTransport` (pont bloquant→paquet),
+    `ProspectPskTlsServer` (DTLS 1.2, identité=user_id), `DTLSHandlerComponent` (pipeline).
+  - `UWorld` sur `NMT_Hello` chiffré : PSK connue → `NMT_EncryptionAck` + handshake.
+  - Compile (0 erreur). **Non validé en live.**
+- **Reste (itération live obligatoire, invalidable hors client)** :
+  1. ordre exact du pipeline `[DTLS, Stateless]` et routage des records de handshake
+     (émis via `LowLevelSend` — doivent porter le framing stateless attendu) ;
+  2. framing DTLS-sur-PacketHandler d'UE (record layer, cookie DTLS éventuel) ;
+  3. bascule handshake→données applicatives.
+  Méthode : lancer `Prospect.Server.Game` avec la PSK, diriger le client dessus, itérer
+  sur les logs serveur.
+
+## MAJ (2026-07-16, soir) — test LIVE contre le vrai client (preprod multi)
+
+Setup : preprod multi (`the-cycle-api-rd2`, `GAMESERVER_ADDRESS=192.168.1.136:7777`) →
+le client voyage vers `the-cycle-game` (branche game-server, PSK via `PROSPECT_DTLS_PSKS`).
+user_id preprod = prod = `92EBCFE8C3EAF3AC` (même DB ? non, `ProspectDb_rd`, mais même Id).
+
+**Observé (séquence réelle) :**
+1. Handshake stateless : ✅ complet (challenge/cookie/ack, connexion acceptée).
+2. `NMT_Hello` reçu **EN CLAIR** avec EncryptionToken=`92EBCFE8C3EAF3AC` → PSK reconnue.
+3. On envoie `NMT_EncryptionAck` + `NMT_Challenge`. Le client **NE ferme plus tout de suite**
+   (progrès vs l'état documenté « ferme après challenge sans ack »).
+4. **Le client n'envoie JAMAIS de ClientHello DTLS** (`16 fe fd`). Aucun record DTLS.
+5. Le paquet suivant du client (~18 o, ex. `80E82AC4…5F00000C`) parse **en clair** comme un
+   **bunch `bClose=true` sur le canal de contrôle (ChIndex 0)** → **le client FERME**.
+
+**Interprétation :** après `NMT_EncryptionAck`, le client attend que les paquets **serveur**
+suivants soient **chiffrés** ; on lui renvoie le `Challenge` en clair → il abandonne. Donc
+l'`EncryptionAck` seul ne suffit pas : il faut réellement **chiffrer la voie serveur** après
+l'ack (le mur crypto de fond, inchangé). Activer notre composant DTLS ne sert à rien tant que
+le client ne fait pas de handshake DTLS de son côté — piste à creuser : est-ce de l'**AES-GCM
+keyé par la PSK** (SetEncryptionData/EnableEncryption d'UE) plutôt que du DTLS-handshake ?
+
+**Bug serveur concret trouvé :** `UChannel.ConditionalCleanUp` (Prospect.Unreal, ~l.822) =
+`throw new NotImplementedException()` → **crash du tick** dès qu'un canal se ferme (bClose).
+À implémenter (indépendant du crypto).
+
+**Acquis réutilisables :** on passe le handshake + le Hello + l'EncryptionAck est accepté ;
+la PSK par user_id est branchée bout-en-bout (Vault → env → serveur). Le blocage net =
+chiffrement de la voie serveur post-ack.
+
+## MAJ (2026-07-16, nuit) — tentative AES-256-GCM keyé par la PSK
+
+Implémenté `AesGcmHandlerComponent` (`System.Security.Cryptography.AesGcm`, format
+`[IV 12o][ciphertext][tag 16o]`), activé après l'EncryptionAck (ack en clair → activation →
+Challenge chiffré). Corrigé aussi l'ordre du pipeline : **Incoming doit itérer en sens
+INVERSE d'Outgoing** (`PacketHandler.Incoming_Internal`) — sinon, avec 2 composants actifs
+(stateless + AES), le stateless tente de parser des octets chiffrés. (Les deux étaient en avant ;
+n'avait jamais compté car un seul composant actif jusqu'ici.)
+
+**Observé (test live) :** notre Challenge part bien chiffré (`[AES] Outgoing 30o→58o`), mais le
+client répond **toujours** par un **paquet plaintext de ~18 o** de structure constante
+(`…41 00 XX FF 5F 00 00 0C`) = un **`bClose` du canal de contrôle**, jamais rien qui ressemble
+à de l'AES (haute entropie ≥28o). **Le client ne chiffre jamais son côté.**
+
+**Conclusion :** quelle que soit notre réponse au `Hello` (challenge clair, chiffré AES, ou
+tentative DTLS), le client **ferme systématiquement le canal de contrôle en clair** juste après.
+L'AES-GCM tel qu'implémenté ne le fait pas basculer en chiffré. Pistes restantes (deep RE, non
+tranchées) : (a) framing AES-GCM exact d'UE (schéma d'IV/nonce, AAD, position) ≠ notre IV aléatoire
+préfixé ; (b) c'est bien du DTLS-handshake et le client attend un ServerHello DTLS ; (c) notre
+réponse au Hello est incomplète (ordre/contenu des NMT) indépendamment du chiffrement.
+Chaque test = ~4 min (CI + redeploy). Bugs serveur secondaires à corriger : `ConditionalCleanUp`
+(stub) + `ArgumentOutOfRangeException` quand on vide un paquet trop court.
+
+**Décision : checkpoint.** Tout est commité/documenté. La suite = RE netcode profonde multi-session ;
+et même résolue, ce n'est que le login — la simulation gameplay reste hors de portée réaliste.
+
+## Flux de chiffrement DTLS d'UE 4.27 (recherche, 2026-07-17)
+
+Sources : KB Epic « Enable Encryption via Packet Handler Components », doc API
+(EnableEncryptionServer/SetEncryptionData/FEncryptionData), UE-95508 (ack chiffré si
+renvoyé), UE-171638 (module DTLS exige OpenSSL), logs DTLS/PSK réels (Satisfactory #453).
+Le source du plugin DTLS est gated (points reconstruits signalés).
+
+**Corrections clés :**
+- **Le CLIENT envoie le ClientHello ; le serveur ATTEND (accept), ne parle jamais en premier.**
+  Donc l'AES-GCM autonome = impasse (c'est bien du DTLS, records `16 fe fd` standard OpenSSL).
+- **`NMT_EncryptionAck` ne porte AUCUNE clé.** À sa réception, le client appelle
+  `ReceivedNetworkEncryptionAck` → **résout lui-même** sa `FEncryptionData` (Key + Identifier)
+  → appelle **`EnableEncryption` côté client** → **c'est CE qui déclenche son ClientHello**.
+- **Séquence serveur** : `SetEncryptionData(Key,Identifier)` → `NMT_EncryptionAck` **en clair, sans
+  payload** → **puis** `EnableEncryption` (mode accept). Ne jamais chiffrer l'ack.
+- **Le `NMT_Challenge` doit être DIFFÉRÉ** : le handler DTLS met les bunches applicatifs en file
+  jusqu'à `Handshaking completed`. (Notre impl l'envoyait tout de suite → à corriger.)
+- **PSK** : PSK = `FEncryptionData.Key`, identité PSK = `FEncryptionData.Identifier` ; ressortie via
+  `DTLSPSKServerCallback` (hook OpenSSL) quand le ClientHello arrive. Le serveur n'envoie jamais la clé.
+- **Couches** : DTLS **sous** le stateless (entrée : retirer stateless puis déchiffrer DTLS ;
+  Outgoing forward / Incoming reverse).
+
+**Si le client ferme SANS ClientHello (notre cas)** → cause la plus probable = **échec de résolution
+de clé côté client** (le vrai client shipping attend peut-être la clé de SON backend/matchmaking,
+non émulé — ou dérivation/Identifier différents), pas notre framing DTLS. C'est potentiellement un
+mur dur (dépend du backend réel du client).
+
+**Test informé RÉALISÉ (2026-07-17)** : `EncryptionAck` seul (clair, sans payload) + DTLS **accept** +
+**PAS de Challenge**. **Résultat : le client n'envoie TOUJOURS pas de ClientHello** (zéro `16 fe fd`
+dans les datagrammes bruts) et ferme avec le `bClose` plaintext habituel.
+
+## VERDICT (mur confirmé) — résolution de clé CÔTÉ CLIENT
+
+Le blocage n'est **pas** notre framing serveur (DTLS ou AES) : le client **n'entame jamais son
+handshake DTLS**. Séquence définitive observée, quel que soit ce qu'on renvoie :
+`stateless OK → NMT_Hello (clair) → notre NMT_EncryptionAck → client ferme (bClose), pas de ClientHello`.
+
+D'après la recherche du flux UE : le ClientHello n'est émis que si le client, dans
+`ReceivedNetworkEncryptionAck`, **résout une `FEncryptionData` valide et appelle `EnableEncryption`
+côté client**. Ici il ne le fait pas → il ferme. On **ne peut pas forcer** ça depuis le serveur.
+
+Cause la plus probable : le vrai client shipping attend sa clé/identité **de SON backend**
+(réponse matchmaking/PlayFab), non émulée — ou une dérivation/`Identifier` qu'on ne fournit pas au
+bon endroit. La PSK a été récupérée (dump mémoire) mais ça ne suffit pas : c'est la **décision
+client d'activer le chiffrement** qui manque, et sa logique vit dans le binaire packé.
+
+**Pour aller plus loin il faudrait** : RE de la fonction `ReceivedNetworkEncryptionAck`/résolution de
+clé du client (dans le `.text` déchiffré, même méthode que pour la PSK) pour savoir **d'où** il attend
+sa clé, puis la lui fournir (probablement côté backend rd2). Chantier RE profond, incertain.
+
+**Statut : mur dur, checkpoint.** Acquis solides et réutilisables : handshake + Hello + EncryptionAck ;
+serveur DTLS-PSK ET AES-GCM implémentés ; ordre pipeline corrigé (Incoming inverse d'Outgoing) ;
+flux UE documenté. Le verrou restant dépend du client, pas du serveur.

+# The Cycle: Frontier — serveur privé (émulateur Prospect)
+
+Émulateur des services en ligne de **The Cycle: Frontier** (jeu retiré de Steam en
+septembre 2022), permettant de rejouer en solo sur un serveur auto-hébergé.
+Fork de [`deiteris/Prospect`](https://github.com/deiteris/Prospect), figé sur le
+**Build 8 / client Saison 2**, buildé depuis les sources et déployé en conteneur via
+une CI Gitea.
+
+> **Ce n'est pas du multijoueur.** Le raid tourne **côté client** (station solo) : chacun
+> joue sa propre instance. Le serveur partage la progression, les comptes et les boutiques,
+> pas la partie. Le vrai multi (squad en raid, voix de proximité) suppose un serveur de jeu
+> Unreal dédié — voir [Hors-périmètre & R&D](#hors-périmètre--rd).

+## Comment ça marche
+
+Le client officiel parle à PlayFab. On l'intercepte côté client et on le redirige vers
+notre serveur, qui réimplémente juste ce qu'il faut de PlayFab (auth Steam, CloudScript,
+UserData/TitleData, matchmaking solo).
+
+```mermaid
+flowchart LR
+  subgraph client [Poste de jeu]
+    L[Prospect.Client.Loader<br/>injecte l'agent] --> A[Prospect.Agent<br/>hooke l'URL PlayFab]
+    A -- lit --> B[backend.txt]
+    A --> G[Jeu &#40;TCF&#41;]
+  end
+  G -- HTTPS / SignalR --> API[Prospect.Server.Api<br/>émulateur PlayFab]
+  API --> M[(MongoDB)]
+```
+
+- **`Prospect.Client.Loader`** lance le jeu en injectant l'agent.
+- **`Prospect.Agent`** hooke l'URL de l'API PlayFab et la remplace par le contenu de
+  **`backend.txt`** (placé dans `Prospect/Binaries/Win64`). Absent → fallback
+  `https://127.0.0.1:8443`.
+- **`Prospect.Server.Api`** émule PlayFab (auth Steam → JWT, CloudScript, données joueur)
+  et pousse le temps-réel via **SignalR**. Les données vivent dans **MongoDB**.
+
+Toute la redirection du client tient donc dans **une seule valeur** (`backend.txt`) — gérée
+par l'outil [`Prospect.Client.Config`](#config-du-client-switch-de-serveur--certificat).
+

+
+## Structure du dépôt
+
+| Projet | Rôle |
+|---|---|
+| **`Prospect.Server.Api`** | Cœur : émulateur PlayFab (ASP.NET 8). Controllers Client/CloudScript/Multiplayer, services Auth/UserData/TitleData/Database(Mongo)/Qos, hub SignalR. |
+| **`Prospect.Steam`** | Validation du ticket Steam (auth). |
+| **`Prospect.Client.Loader`** | Loader C++ : lance le jeu et injecte l'agent. |
+| **`Prospect.Agent`** | Agent C++ injecté : hooke l'URL PlayFab → `backend.txt`. |
+| **`Prospect.Client.Config`** | Utilitaire multi-OS : écrit `backend.txt`, importe le certificat, lance le jeu. Voir son [README](src/Prospect.Client.Config/README.md). |
+| **`Prospect.Server.Game`** | Serveur de jeu dédié (squelette, **R&D**). |
+| **`Prospect.Unreal[.Generator/.Tests]`** | Réimplémentation C# du netcode Unreal (**R&D** serveur dédié). |
+| `utils/` | `generate_ssl.py` — génération du certificat auto-signé. |

-## Running locally
+## Build & lancement du serveur
 
-> [!NOTE]
-> If you've already done all steps previously, you can skip to Step 7.
+Le serveur tourne en conteneur. L'image est buildée depuis les sources par le
+[`Dockerfile`](Dockerfile) (multi-stage SDK .NET 8 → runtime aspnet 8, publish en
+`Season 2 Release`).
 
-### 1. Prerequisites
+### Build de l'image
+
+```bash
+docker build -t the-cycle .
+```
+
+### Lancement
+
+Il faut une **instance MongoDB** joignable et un **certificat TLS** monté (voir section
+suivante). Variables d'environnement :
+
+| Variable | Rôle |
+|---|---|
+| `DatabaseSettings__ConnectionString` | URI de connexion MongoDB. |
+| `DatabaseSettings__DatabaseName` | Base à utiliser (ex. `ProspectDb`). |
+| `AuthTokenSettings__Secret` | Secret de signature des JWT émis par le serveur. |
+| `PlayFabSettings__SignalRURL` | URL SignalR **telle que le client doit l'atteindre** (voir gotcha ci-dessous). |
+| `Kestrel__Certificates__Default__Path` | Chemin du `.pfx` dans le conteneur. |
+| `Kestrel__Endpoints__Https__Url` | ex. `https://0.0.0.0:8443`. |
+| `SteamWebApiKey` | *(optionnel)* clé Steam Web API pour récupérer les pseudos ; inerte si absente. |
 
-> [!WARNING]
-> The latest Steam version of The Cycle: Frontier currently does not work with Windows 11 24H2!
+```bash
+docker run -d --name the-cycle-api \
+  -e DatabaseSettings__ConnectionString="mongodb://user:pass@HOST:27017/?authSource=ProspectDb" \
+  -e DatabaseSettings__DatabaseName="ProspectDb" \
+  -e AuthTokenSettings__Secret="<secret>" \
+  -e PlayFabSettings__SignalRURL="https://<host-public>:8443/signalr/?hub=pubsub" \
+  -e Kestrel__Endpoints__Https__Url="https://0.0.0.0:8443" \
+  -e Kestrel__Certificates__Default__Path="/certs/certificate.pfx" \
+  -v "$PWD/certs:/certs:ro" \
+  -p 8443:8443 \
+  the-cycle
+```
+
+> ⚠️ **`PlayFabSettings__SignalRURL` = l'URL que le CLIENT doit joindre**, pas `127.0.0.1`.
+> Le serveur y renvoie le client pour l'event de matchmaking ; s'il pointe sur `127.0.0.1`,
+> le déploiement en raid **timeout**. Mets le hostname/IP public du serveur.
+
+### Dev local (.NET)
+
+```bash
+dotnet build src/Prospect.Server.Api/Prospect.Server.Api.csproj -c "Season 2 Release"
+dotnet run  --project src/Prospect.Server.Api -c "Season 2 Release"
+```
+
+---
+
+## Certificat TLS
+
+La connexion est en HTTPS et le client valide le certificat → il doit être **auto-signé et
+fait confiance** côté client. Générer le `.pfx` avec `utils/generate_ssl.py`.
+
+> ⚠️ **Le SAN doit contenir `DNS:<ip>` ET `IP:<ip>`**, en plus des hostnames.
+> Le HTTP du jeu (libcurl) accepte l'IP en SAN IP, mais le WebSocket (libwebsockets) valide
+> l'IP contre les SAN **DNS** → sans `DNS:<ip>`, la connexion SignalR échoue
+> (`Hostname mismatch err=62`). Inclure aussi `2EA46.playfabapi.com`, `localhost`,
+> `127.0.0.1` et tous les hostnames publics utilisés dans `backend.txt`.
+
+Côté client, l'import du certificat est automatisé par
+[`Prospect.Client.Config`](#config-du-client-switch-de-serveur--certificat).
 
-> [!IMPORTANT]
-> You must have The Cycle: Frontier from Steam in your Steam library to be able to download it.
-> Otherwise, the download will fail with an error message about missing license.

-Before you start, you'll need the following software downloaded and installed:
+## CI/CD
 
-1. [MongoDB Community Edition](https://fastdl.mongodb.org/windows/mongodb-windows-x86_64-8.0.4-signed.msi).
+[`.gitea/workflows/build.yml`](.gitea/workflows/build.yml) — sur push `main` / `preprod`
+(ou `workflow_dispatch`) :
 
-1. [`Prospect.Server.Api` and `LoaderPack`](https://github.com/deiteris/Prospect/releases) from the Releases section:
+1. build de l'image depuis le `Dockerfile` ;
+2. push sur le registry `git.nfteam.ovh/neckfire/the-cycle` ;
+3. notification du résultat (ntfy).
 
-   - For Season 3 (the latest Steam game client), use Build 6.
+**Modèle de branches :**
 
-   - For Season 2 game client, use the latest version.
+| Branche | Tag image | Usage |
+|---|---|---|
+| `preprod` | `:preprod` (+ `:preprod-<sha>`) | banc de test — valider un build avant de merger |
+| `main` | `:latest` (+ `:<sha>`) | production |
 
-1. The Cycle: Frontier game client:
+Workflow type : coder → push `preprod` → tester sur le serveur preprod → **PR `preprod → main`**
+→ la CI republie `:latest`. Le déploiement applique la nouvelle image
+(`docker compose pull && docker compose up -d`).
 
-   - The latest version from [Steam](https://steamcommunity.com/app/868270).
+> `Prospect.Client.Config` (outil client, cross-OS) n'est **pas** buildé par cette CI —
+> voir sa section publication.
 
-   - Season 2 client version `4623363103423775682` from SteamDB. See [download instructions below](#11-how-to-download-season-2-client-from-steamdb-using-steam-console).

-#### 1.1 How to download Season 2 client from SteamDB using Steam console
+## Config du client (switch de serveur + certificat)
 
-> [!WARNING]
-> This will overwrite the existing client if you try to download a different manifest!
+L'outil **`Prospect.Client.Config`** (binaire `ProspectServerSwitcher`, multi-OS
+Linux/Proton + Windows) fait tout le boulot côté client :
 
-1. With Steam running, press `Win+R` and enter `steam://nav/console`. A Steam console will open.
+- écrit `backend.txt` (presets **prod** / **preprod** ou URL libre) ;
+- récupère le certificat **en direct depuis le serveur ciblé** (TLS) et le rend fiable :
+  - **Windows** : import dans *Autorités de certification racines de confiance* (utilisateur) ;
+  - **Linux/Proton** : import direct dans le préfixe Wine du jeu via `wine reg import`
+    (car `wine certutil` est cassé sous Proton) ;
+- lance le jeu.
 
-1. Open [The Cycle: Frontier SteamDB manifests](https://steamdb.info/depot/868271/manifests/).
+```bash
+# menu interactif
+ProspectServerSwitcher
 
-1. Make sure you have **Copy format** set to **Steam console**.
+# scriptable
+ProspectServerSwitcher --folder "<...>/Prospect/Binaries/Win64" --set preprod
+ProspectServerSwitcher --set https://mon-serveur:8443
+```
 
-1. Press `CTRL+F` and enter `4623363103423775682` to find the manifest for Season 2 version 2.7.2 client.
+Détails complets, gotchas Proton (préfixe non-Steam) et commandes de publication des
+binaires autonomes : **[src/Prospect.Client.Config/README.md](src/Prospect.Client.Config/README.md)**.
+
+> Installation complète pas-à-pas pour un nouveau joueur (télécharger le client S2, le
+> LoaderPack, importer le certificat) : **[FRIENDS-INSTALL.md](FRIENDS-INSTALL.md)**.
 
-1. Click the ![Copy](./_assets/steamdb_copy.PNG) icon to copy the download command.
+---
 
-1. Paste the command in the Steam console and press `Enter`.
+## État des fonctionnalités
 
-1. The depot will begin downloading. You should receive a notification and the destination folder when the download is complete.
+**Fonctionne :**
 
-### 2. Unpack `Prospect.Server.Api`
+- [x] Login Steam, EULA, tutoriel
+- [x] Station solo (S2/S3) : onboarding, matchmaking & déploiement **solo**
+- [x] Inventaire & loadout, stash, vente, réparation
+- [x] Contrats / quêtes — y compris les objectifs **kills** et **de zone** (auto-crédités :

-Use your favorite ZIP archiver and unzip the `Prospect.Server.Api.zip` downloaded from this repository.
+**Non implémenté / hors-périmètre :**
 
-### 3. Generate and import SSL certificate
+- [ ] Squad / multi dans le **même** raid — nécessite un serveur de jeu dédié
+- [ ] Voix de proximité (login/join Vivox = placeholders)
+- [ ] Free loadouts & presets (Saison 3 uniquement)
+- [ ] Achat de cosmétiques (endpoint d'achat vanity distinct, non câblé)
+- [ ] Catalogue des récompenses Fortuna (DataTable côté client, dans des paks chiffrés)
+- [ ] Défis quotidiens Fortuna
 
-> [!IMPORTANT]
-> Do not share the generated certificate! Generated certificate includes a private key that may be used to generate other certificates and compromise your security.
+---
 
-A connection to the server is served over a secured connection. The server uses self-signed certificate that must be added to trusted authorities in order for the game
-to successfully communicate with the local server. Do the following:
+## Hors-périmètre & R&D
 
-1. Open the folder with `Prospect.Server.Api`.
+Un **serveur de jeu Unreal dédié** (`Prospect.Server.Game` + `Prospect.Unreal`, branche
+`game-server`) est en cours de reverse-engineering pour, à terme, permettre le vrai multi.
+État : handshake stateless UE, séquençage et décodage des bunches **franchis**, canal de
+contrôle ouvert, `NMT_Hello` parsé. **Bloqué** sur le chiffrement **DTLS-PSK** du client
+(clé dérivée du `user_id`), derrière un exe packé (BattlEye) → la dérivation n'est pas
+extractible statiquement. Détails dans `NETCODE-RND.md` (branche `game-server`).
 
-1. Double-click `generate_ssl.exe`. `certificate.pfx` will appear in the same folder.
+Le « lobby squad » via l'API seule n'est **pas faisable** : l'invitation d'amis est gérée
+100 % côté client Steam.
 
-1. Double-click `certificate.pfx`. The Certificate Import Wizard will open:
+---
 
-    1. Select **Current User** under Store Location and click **Next**.
+## Crédits & licence
 
-    1. Leave **File to Import** unchanged and click **Next**.
-
-    1. Leave **Password** empty and click **Next**.
-
-    1. Select **Place all certificates in the following store** > **Browse...**. Choose **Trusted Root Certification Authorities** and click **OK**. Click **Next**.
-
-    1. Click **Finish**. A **Security Warning** popup may appear, make sure it specifies `2EA46.playfabapi.com` certification authority and click **Yes**.
-
-### 4. Extract `LoaderPack` to the game
-
-1. Open the folder with The Cycle: Frontier and navigate to **Prospect** > **Binaries** > **Win64**.
-
-1. Open the `LoaderPack` archive.
-
-1. Drag and drop the contents of the `LoaderPack` archive to the game.
-
-1. Create a shortcut for the `Prospect.Client.Loader` that you will use later to launch the game.
-
-### 5. Run the server
-
-Now you are all set! Open the folder with `Prospect.Server.Api` and run `Prospect.Server.Api.exe`. It will open a console if it runs successfully.
-
-> [!IMPORTANT]
-> Do not close the console when you run the game.
-
-### 6. Run the game
-
-Once the server is running, make sure that Steam is running and open The Cycle: Frontier using the shortcut you've created before.
-
-## Troubleshooting and FAQ
-
-### How to remove the certificate?
-
-If you've installed the certificate for the **Current User**:
-
-1. Open **Start** and enter `certmgr.msc`.
-
-1. Expand **Trusted Root Certification Authorities** and select **Certificates**.
-
-1. Find `2EA46.playfabapi.com`, right-click it > **Delete**.
-
-If you've installed the certificate for the **Local Machine**, repeat the same steps but instead open `certlm.msc`.
-
-### `generate_ssl.exe` is flagged as a virus
-
-`generate_ssl.exe` is a Python application packed with PyInstaller and some anti-viruses may flag it as a virus.
-This application is a simple certificate generator and you can find its source code in `utils/generate_ssl.py`.
-
-### Body parts are missing with Season 3 client
-
-Currently, the server loads body part IDs for Season 2 by default, so this is expected. You can fix this by going to station and changing your character appearance. This will store the updated body part IDs for your character.
-
-### Prospect.Server.Api does not start
-
-Make sure you have [.NET Runtime 8.0](https://aka.ms/dotnet-core-applaunch?missing_runtime=true&arch=x64&rid=win-x64&os=win10&apphost_version=8.0.11) and [ASP.NET Core 8.0](https://aka.ms/dotnet-core-applaunch?framework=Microsoft.AspNetCore.App&framework_version=8.0.0&arch=x64&rid=win-x64&os=win10) installed.
-
-### Login Failed. Error code: 3
-
-Make sure that:
-
-* You have Steam running.
-* You have created and **saved** the `steam_appid` file as described in step 6.
-* The `steam_appid` file type is "TXT File".
-
-### Login Failed. Error code: 5
-
-Make sure that `Prospect.Server.Api` server is running.
-
-If the server is running, press `Alt+Tab` to a game console that opens when you start the game and check for the following:
-
-* `libcurl error 7 (Couldn't connect to server)` - indicates that the `Prospect.Server.Api` is not running.
-  ![](./_assets/connection_refused_error.png)
-
-* `InvalidAPIEndpoint` - indicates that you are running the game using the original shortcut and not using `Prospect.Client.Loader`.
-  ![](./_assets/invalid_api_endpoint.PNG)
-
-* `libcurl error 60 (Peer certificate cannot be authenticated with given CA certificates)` - indicates that the certificate was not installed correctly. Make sure that the certificate is present in `certmgr.msc` and there is only one certificate. Try removing the certificate and importing it again by following step 4.
-  ![](./_assets/certificate_error.PNG)
-
-* `HTTP code: 500` - usually indicates that MongoDB is not running. Make sure that MongoDB is installed and and that `MongoDB Server` is running in `services.msc`.

+# Étude — Émulation PlayFab Groups/Party pour l'invite de squad
+
+> Objectif : permettre à un joueur d'**inviter un ami** à faire équipe (squad) sur le serveur
+> privé. Étude du mécanisme, de l'état actuel, d'une conception d'émulation et d'un plan.
+> Branche : `game-server`.
+
+## 1. État actuel (ce qui existe déjà)
+
+**Roster de squad en mémoire** — `Services/Squad/SquadService.cs` :
+- Squads clés par un **`squadId` fourni par le client** (`JoinOrCreate(squadId, userId, …)`).
+- Membre = profil (playerId, displayName), `onlineState`, `isReady`, `selectedMap`, `isLeader`.
+- `_userToSquad` permet à `TryGetCompleteSquadInfo` (qui ne porte pas de squadId) de retrouver la squad du joueur.
+
+**Fonctions CloudScript squad présentes** : `TryGetCompleteSquadInfo`, `SquadMemberReadyForMatch`
+(pousse déjà via SignalR), `SquadMemberSelectedMap`, `SquadMemberStartingDeployFlow`,
+`GetFriendList`, `ClientsideFriendsImport`.
+
+**Ce qui MANQUE** (cœur du problème) : aucune fonction de **création de squad**, d'**invitation**,
+d'**acceptation/refus**, de **join/leave/kick**. Le flux actuel suppose que le client **connaît déjà
+un `squadId`** (party formée ailleurs) et se contente d'y rattacher les membres.
+
+**Infra de push temps-réel DISPONIBLE** — `Hubs/CycleHub.cs` + `Hubs/SignalRConnectionRegistry.cs` :
+le client se connecte au hub avec `?uid=<playerId>` ; le registry mappe `uid → connectionId`. Le
+serveur peut donc **pousser un message ciblé** à un joueur précis (`registry.GetConnection(uid)` +
+`IHubContext<CycleHub>.Clients.Client(conn).SendAsync(<event>, payload)`). C'est déjà utilisé par
+`SquadMemberReadyForMatch` et par le signal « travel to match » du matchmaking. **→ Le canal de
+livraison de l'invite existe déjà.**
+
+## 2. Comment The Cycle forme-t-il les squads ? (hypothèses + preuves)
+
+Le `squadId` étant **fourni par le client**, la party est créée là où le client obtient cet id.
+Quatre mécanismes candidats côté PlayFab/Steam :
+
+| # | Mécanisme | Ce que ça implique côté serveur | Indice |
+|---|---|---|---|
+| A | **PlayFab Entity Groups** (`/Group/CreateGroup`, `/Group/InviteToGroup`, `/Group/AcceptGroupInvitation`, `/Group/ListGroupMembers`…) | Implémenter le sous-ensemble Groups (entités déjà émulées). `squadId` = group entity id. | Fort : squads persistantes chez PlayFab passent par Groups ; l'id opaque partagé colle. |
+| B | **PlayFab Lobby** (Multiplayer : `CreateLobby`/`JoinLobby`/`InviteToLobby` via connection string) | Implémenter l'API Lobby. `squadId` = lobbyId. | Moyen : plutôt matchmaking S3+. |
+| C | **Lobby Steam** (invite via overlay Steam) + backend qui suit | Rien à créer pour l'invite (100% Steam) ; le serveur ne fait que suivre le `squadId` rapporté. | Moyen : S2 = Steam-only ; explique le `squadId` client. Mais alors l'invite n'est pas pilotable serveur. |
+| D | **Fonctions CloudScript d'invite** (non observées) | Implémenter `InvitePlayerToSquad`/`RespondToSquadInvite`/… | Faible : aucune trace. |
+
+**Preuve manquante (bloquant)** : les logs prod de la session à 2 ont été **écrasés** par nos
+redéploiements. Impossible aujourd'hui de voir l'appel exact d'invite. De plus, l'émulateur peut
+**404 silencieusement** un endpoint PlayFab natif non routé (ex. `/Group/CreateGroup`) → un tel
+appel n'apparaît pas comme fonction CloudScript. **Il faut donc capturer l'appel réel** (voir §5,
+Phase 0) — d'autant que le **bouton « inviter » n'apparaît pas tant que la tuile ami est vide**
+(bug de forme `GetFriendList`, corrigé PR #15, à valider en jeu). Tant que la liste d'amis ne
+s'affiche pas, aucune invite ne peut même être tentée.
+
+## 3. Conception d'émulation proposée (indépendante du mécanisme exact)
+
+Quel que soit A/B/C/D, les briques serveur à construire sont les mêmes :
+
+**3.1 Étendre `SquadService`** (états d'invite) :
+- `CreateSquad(leaderUserId) → squadId` (GUID serveur si le client n'en impose pas).
+- `Invite(squadId, fromUserId, toUserId)` → enregistre une **invitation en attente** `{squadId, from, to, expiresAt}`.
+- `RespondToInvite(toUserId, squadId, accept)` → si accept : `JoinOrCreate` ; sinon purge.
+- `Leave` / `Kick(byLeader)` / transfert de leadership à la sortie du leader.
+- `GetPendingInvites(userId)` (fallback poll).
+
+**3.2 Surface d'API** — deux options selon la capture (§5) :
+- **Si Groups (A)** : router `POST /Group/CreateGroup`, `/Group/InviteToGroup`,
+  `/Group/AcceptGroupInvitation`, `/Group/ListGroupMembers`, `/Group/RemoveMembers` vers
+  `SquadService` (les EntityToken sont déjà émulés). C'est le plus « natif ».
+- **Si CloudScript (D) / custom** : ajouter les fonctions `[CloudScriptFunction(...)]`
+  correspondantes (noms/shapes calqués sur la capture).
+- **Si Steam (C)** : rien pour l'invite (Steam) ; s'assurer seulement que le roster se peuple bien
+  quand les deux clients rapportent le même `squadId` (déjà géré par `SquadService`).
+
+**3.3 Livraison temps-réel de l'invite** (réutilise l'infra existante) :
+- À l'invitation, pousser à l'invité : `registry.GetConnection(toUserId)` +
+  `hub.Clients.Client(conn).SendAsync("<SquadInviteReceived>", payload)`.
+- **Nom d'event + payload = à confirmer côté client** (le client doit écouter cet event). Fallback :
+  `GetPendingSquadInvites` (CloudScript) que le client poll à l'ouverture du menu social.
+
+**3.4 Persistance** : le roster peut rester en mémoire (petit serveur), mais les invitations
+gagnent à être **persistées** (UserData `PendingSquadInvites`) pour survivre à un reload/redeploy et
+au cas « ami à la station » — combiné au push SignalR.
+
+## 4. Limite structurelle importante (à dire clairement)
+
+Émuler l'invite permet de **former une squad et de se mettre prêt** ensemble (lobby/ready-up).
+Mais **déployer réellement ensemble dans le même raid** nécessite le **serveur de jeu dédié**
+(`Prospect.Server.Game`), qui est bloqué au mur **DTLS-PSK** (cf. reste de cette branche). Les raids
+S2 sont **hébergés côté client** (solo) : sans serveur dédié, deux joueurs ne peuvent pas partager
+la même instance de raid. Donc :
+- **Invite + squad + ready-up** : émulable via l'API (cette étude).
+- **Co-op en raid** : dépend du serveur dédié (autre chantier, DTLS-PSK).
+
+## 5. Plan par phases
+
+- **Phase 0 — Capture (débloque tout)** : valider le fix `GetFriendList` en jeu (la tuile ami doit
+  afficher le pseudo) → le bouton « inviter » réapparaît → tenter une invite et **capturer les
+  appels** (ajouter un logging *catch-all* des requêtes non routées + corps, pour voir un éventuel
+  `/Group/…` 404). Résultat : on sait A/B/C/D.
+- **Phase 1 — Invite** : implémenter la surface identifiée + états `SquadService` + push SignalR ;
+  persister les invitations.
+- **Phase 2 — Ready-up/déploiement groupé** : compléter (déjà amorcé) ; le déploiement co-op réel
+  reste gated par le serveur dédié.
+
+## 6. Prochaine action concrète
+Repro en jeu (liste d'amis corrigée) + logging catch-all → capturer l'appel d'invite. Sans cette
+capture, toute implémentation d'invite serait une supposition sur les noms/shapes attendus par le
+client (paks chiffrés → pas de RE statique).

+# ProspectServerSwitcher
+
+Petit utilitaire **multi-OS** (Linux/Proton + Windows) pour pointer un client
+*The Cycle: Frontier* vers un serveur, importer le certificat, et lancer le jeu.
+
+## Pourquoi
+
+L'agent Prospect (`Prospect.Agent.dll`, injecté par `Prospect.Client.Loader.exe`)
+hooke l'URL de l'API PlayFab et la remplace par le contenu de **`backend.txt`**,
+placé à côté de l'exécutable du jeu (`Prospect/Binaries/Win64`). S'il est absent,
+l'agent retombe sur `https://127.0.0.1:8443`.
+
+**Tout l'aiguillage du client tient donc dans cette seule valeur.** Cet outil ne fait
+essentiellement qu'écrire le bon `backend.txt` — plus quelques commodités (cert, launch).
+
+## Serveurs (presets)
+
+Les presets utilisent les **domaines publics** pour que la même cible marche pour
+tout le monde (le DNS résout vers l'IP publique pour les amis, et le certificat TLS
+unifié couvre les deux hostnames) :
+
+| Preset    | URL                              |
+|-----------|----------------------------------|
+| `prod`    | `https://tc.nfteam.ovh:8443`     |
+| `preprod` | `https://rd-tc.nfteam.ovh:8444`  |
+
+> **Sur le même LAN que le serveur**, ajoute une entrée hosts pour éviter le hairpin NAT :
+> ```
+> 192.168.1.136   tc.nfteam.ovh
+> 192.168.1.136   rd-tc.nfteam.ovh
+> ```
+
+## Utilisation
+
+### Menu interactif
+Lance le binaire sans argument :
+- **1** : définir le dossier du jeu (`…/Prospect/Binaries/Win64`) — mémorisé
+- **2/3** : basculer sur PROD / PREPROD
+- **4** : URL personnalisée
+- **5** : importer un certificat (`.crt`)
+- **6** : lancer le jeu
+- **0** : quitter
+
+### En ligne de commande (scriptable)
+```
+ProspectServerSwitcher --folder "<...>/Prospect/Binaries/Win64" --set preprod
+ProspectServerSwitcher --set prod
+ProspectServerSwitcher --set https://mon-serveur:8443   # URL libre
+```
+
+> ⚠️ `backend.txt` n'est lu qu'**au démarrage** du loader → relance le jeu après un switch.
+> Le serveur ciblé doit **tourner** (conteneurs on-demand `the-cycle-api` / `the-cycle-api-rd`).
+
+## Certificat
+
+L'outil récupère le certificat **en direct depuis le serveur** ciblé (il lit `backend.txt`
+et se connecte en TLS), puis le rend fiable :
+
+- **Windows** : import automatique dans *Autorités de certification racines de confiance*
+  (utilisateur courant), via le magasin `X509Store`.
+- **Linux/Proton** : import **automatique dans le préfixe Wine** du jeu. Comme `wine certutil`
+  est cassé sous Proton, l'outil écrit directement le *blob* sérialisé du certificat
+  (propriété SHA1 `id=3` + certificat encodé `id=0x20`) dans le magasin `Root` du préfixe via
+  `wine reg import`. Il :
+  1. détecte le binaire `wine` de Proton (`…/common/Proton*/files/bin/wine`),
+  2. liste les préfixes `compatdata/*/pfx` (le plus récemment utilisé en premier),
+  3. importe dans le préfixe choisi (⚠️ **le jeu doit être fermé**), mémorisé ensuite.
+
+  > ⚠️ Le client tourne souvent comme **raccourci non-Steam** → son préfixe n'est **pas**
+  > `compatdata/868270` mais un appid généré (ex. `3883998305`). D'où la sélection explicite
+  > du préfixe plutôt qu'une déduction sur l'appid du jeu.
+
+## Lancement
+
+- **Windows** : démarre `Prospect.Client.Loader.exe` depuis le dossier du jeu.
+- **Linux/Proton** : passe par Steam (`steam steam://rungameid/868270`) — le loader doit
+  tourner dans le préfixe Proton.
+
+## Réglages
+
+Le dossier du jeu est mémorisé dans
+`…/ApplicationData/ProspectSwitcher/settings.json`
+(`%AppData%` sous Windows, `~/.config` sous Linux).
+
+## Build / publication
+
+Projet console **net8.0** (cross-platform, `InvariantGlobalization`), jamais buildé par
+la CI serveur (Linux).
+
+```bash
+# build simple
+dotnet build src/Prospect.Client.Config -c Release
+
+# binaires autonomes single-file (aucun .NET requis chez l'utilisateur)
+dotnet publish src/Prospect.Client.Config -c Release -r win-x64   --self-contained \
+  -p:PublishSingleFile=true -p:IncludeNativeLibrariesForSelfExtract=true -p:EnableCompressionInSingleFile=true
+dotnet publish src/Prospect.Client.Config -c Release -r linux-x64 --self-contained \
+  -p:PublishSingleFile=true -p:EnableCompressionInSingleFile=true
+```
+
+Les binaires publiés sont distribués via la release Gitea **`friends-client`**
+(`ProspectServerSwitcher.exe` pour Windows, `ProspectServerSwitcher-linux-x64` pour Linux).
