Merge pull request 'capture: catch-all logging for squad-invite RE (unrouted + social)' (#17) from preprod into main

Log every unrouted POST at Warning [CAPTURE UNROUTED] (reveals native PlayFab
endpoints the emulator doesn't implement, e.g. /Group/CreateGroup, /Lobby/*) and
every social/squad/invite/friend/matchmaking call (path or body) at Information
[CAPTURE SOCIAL]. Lets us pin the exact invite mechanism when reproduced in game.

+## 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]
+Le serveur tourne en conteneur. L'image est buildée depuis les sources par le
-> If you've already done all steps previously, you can skip to Step 7.
+[`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]
+```bash
-> The latest Steam version of The Cycle: Frontier currently does not work with Windows 11 24H2!
+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>" \

+  -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 —

-> [!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
+## Hors-périmètre & R&D
-to successfully communicate with the local server. Do the following:
 
-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**.
+Fork de [`deiteris/Prospect`](https://github.com/deiteris/Prospect) (lui-même issu du
-
+projet Prospect original). Voir [`LICENSE`](LICENSE). Usage privé.
-    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`.
