+## What's Changed
+
+### Nouvelles fonctionnalités
+
+- **Nature des échanges** — les commentaires de transactions sont analysés et classés automatiquement en catégories : don & gratitude, alimentation, soin & bien-être, vêtements, culture & loisirs, événement, service & travaux, remboursement, migration, ticket, autre
+- Distribution des catégories affichée dans le panneau latéral (barres proportionnelles sur les transactions commentées de la période) — chaque catégorie est cliquable pour dérouler la liste des transactions avec leur commentaire et montant
+- Tooltip au survol des arcs en vue Flux : répartition des catégories + échantillon de commentaires bruts du corridor
+- 76 % des transactions Ğ1v2 comportent un commentaire — le champ `remark` est désormais fetché depuis SubSquid
+
+### Améliorations
+
+- InfoPanel mis à jour : section *Nature des échanges* documentée
+
+### Détails techniques
+
+- Nouveau `src/data/commentParser.ts` — ~80 règles regex multilingues (FR/ES/CA/IT/EN/PT), 11 catégories, priorité ordonnée
+- `SubsquidAdapter` : ajout de `comment { remark }` à la query GraphQL
+- `Transaction` et `TransactionArc` : nouveaux champs `comment: string | null` et `category: TxCategory`
+- `Corridor` : nouveaux champs `categories` (agrégées) et `comments` (échantillon jusqu'à 5)
+- `PeriodStats` : nouveaux champs `categoryBreakdown` et `commentedCount`
+- Zone de hit des arcs SVG élargie (+8 px) pour faciliter le survol
+- Aucune nouvelle dépendance npm
+
