 ## 🚢 Deployment guide
 
+The security baseline for source builds is **Go 1.26.10**, which includes the certificate verification fix for CVE-2026-111943. Recompile with the patched toolchain and replace the backend binary when upgrading; installing a newer Go version or restarting an old binary does not update its standard library. CI and Docker builds use this version consistently.
+
 The following steps use a stable release as an example. Pin the version tag and commit, and complete backup, verification, and rollback preparation before upgrading.

 ## 🚢 Guide de déploiement
 
+La référence de sécurité pour les compilations depuis les sources est **Go 1.26.10**, qui inclut le correctif de vérification des certificats pour CVE-2026-111943. Recompilez avec la chaîne d'outils corrigée et remplacez le binaire du backend lors de la mise à niveau ; installer une nouvelle version de Go ou redémarrer un ancien binaire ne met pas à jour sa bibliothèque standard. Les compilations CI et Docker utilisent cette même version.
+
 Les étapes suivantes prennent une version stable comme exemple. Figez le tag et le commit utilisés, puis préparez la sauvegarde, la vérification et le retour arrière avant toute mise à niveau.

+ソースからビルドする際のセキュリティ基準は **Go 1.26.10** です。CVE-2026-111943 の証明書検証修正が含まれます。更新時は修正済みツールチェーンで再コンパイルし、バックエンドの実行ファイルを置き換えてください。Go のインストール更新や古い実行ファイルの再起動だけでは、組み込まれた標準ライブラリは更新されません。CI と Docker でも同じバージョンを使用します。
+
 以下の手順は正式版を例にしています。使用するバージョンタグとコミットを固定し、アップグレード前にバックアップ、検証、ロールバックの準備を完了してください。

+Build the backend with **Go 1.26.10** before packaging Electron. This is the security baseline for CVE-2026-111943; replace any previously built backend binary, since rebuilding only the Electron wrapper does not update Go's embedded standard library.
