+# Ticket #006
+
+## Titre
+
+Créer le module `Workspace`.
+
+---
+
+## Objectif
+
+Créer un composant graphique représentant la zone principale de travail de Labfy Investigation.
+
+Le module doit être indépendant du reste de l'interface afin de pouvoir évoluer sans modifier `MainWindow`.
+
+---
+
+## Responsabilités
+
+Le module `Workspace` doit :
+
+- créer la zone centrale de l'application ;
+- afficher une page d'accueil lorsqu'aucune enquête n'est ouverte ;
+- fournir un widget racine réutilisable ;
+- gérer uniquement son interface graphique.
+
+---
+
+## Hors périmètre
+
+Ce ticket ne doit pas :
+
+- afficher les preuves ;
+- afficher les entités ;
+- afficher un PDF ;
+- afficher une image ;
+- communiquer avec SQLite ;
+- charger une enquête.
+
+---
+
+## Architecture
+
+```text
+MainWindow
+├── Sidebar
+├── Workspace
+└── StatusBar
+```
+
+Le module appartient à la couche **Widgets**.
+
+Aucune logique métier.
+
+---
+
+## Fichiers concernés
+
+```text
+include/widgets/workspace.h
+src/widgets/workspace.c
+```
+
+---
+
+## Interface publique
+
+```c
+Workspace *workspace_new(void);
+
+GtkWidget *workspace_get_widget(
+    const Workspace *workspace
+);
+
+void workspace_free(
+    Workspace *workspace
+);
+```
+
+---
+
+## Interface graphique attendue
+
+```text

+|             Aucune enquête ouverte                          |
+|                                                             |
+|         Sélectionnez ou créez une enquête                   |
+|                                                             |
+|                                                             |
++-------------------------------------------------------------+
+```
+
+---
+
+## Évolutions prévues
+
+Cette zone accueillera plus tard :
+
+- visualiseur d'image ;
+- lecteur PDF ;
+- chronologie ;
+- fiche personne ;
+- fiche IBAN ;
+- fiche email ;
+- fiche téléphone ;
+- rapports ;
+- cartes ;
+- résultats OSINT.
+
+Le module doit donc rester générique.
+
+---
+
+## Contraintes
+
+- GTK4 uniquement ;
+- structure opaque ;
+- aucune variable globale ;
+- documentation Doxygen ;
+- C17 ;
+- compilation sans warning.
+
+---
+
+## Critères d'acceptation
+
+- [ ] Le projet compile.
+- [ ] Le Workspace apparaît dans MainWindow.
+- [ ] Le texte d'accueil est centré.
+- [ ] Sidebar et Workspace sont totalement indépendants.
+- [ ] Aucun warning.
+- [ ] Aucun Gtk-CRITICAL.
+
+---
+
+## Tests
+
+- lancement ;
+- redimensionnement de la fenêtre ;
+- fermeture ;
+- vérification visuelle.
+
