📝 Changelog - XtremFlow Optimisations

Version 1.2 - Security, Streaming & Design Overhaul (10 Juin 2026)

🔐 Sécurité

• Hachage des mots de passe en bcrypt (migration lazy depuis SHA-256 au login)
• Les credentials Xtream ne quittent plus jamais le serveur : nouvelle passerelle authentifiée /api/xtream-api (injection côté serveur), /api/playlists ne renvoie plus les mots de passe
• Redaction des credentials dans tous les logs (proxy, FFmpeg, scheduler, login)
• Cookie de session HttpOnly + auth sur les routes de streaming, recordings, EPG, season-passes
• postMessage des players verrouillé sur same-origin (plus de wildcard *)
• hls.js 1.6.7 / mpegts.js 1.7.3 vendorisés et figés (web/vendor/, plus de CDN @latest)
• Rate limiter réparé (IP réelle via X-Forwarded-For) + limite login 10/min/IP
• CORS restreint (plus de wildcard), CSP en Report-Only, anti-SSRF (IP privées bloquées), fix path-traversal sur les logs d'enregistrement, chmod 770 sur /app/recordings
• Suppression du code mort HiveService (seed admin SHA-256 en IndexedDB)

📺 Streaming

• FfmpegSessionManager : registre des process FFmpeg, reaper d'inactivité (4 min live / 15 min VOD), purge des orphelins au démarrage, arrêt propre SIGTERM, échec rapide avec stderr (fini le timeout 30 s)
• Sélection de qualité : source | high | medium | low (live + VOD), source = -c:v copy zéro transcodage ; sélecteur dans le player
• Enregistrements simultanés (MAX_CONCURRENT_RECORDINGS, défaut 2) : les conflits réessaient au lieu d'échouer
• Latence live réduite : fenêtre HLS 20→10 segments, liveSyncDurationCount 10→3
• Fix : récupération des logs d'enregistrement (cherchait .mp4, fichiers en .mkv)
• Fix : authMiddleware ne peuplait pas user → getPlaylist retombait toujours sur le 1er utilisateur, purge admin toujours 403

🎨 Design

• Sweep des couleurs hardcodées → tokens AppColors (24 occurrences, 12 fichiers)
• web/theme.css : variables CSS synchronisées avec le thème Flutter pour les 3 players HTML
• Navigation DPAD/clavier : flèches = focus, raccourcis player (espace, ←/→ seek/zap, M mute, Échap)
• Tooltips sur tous les boutons icône du player, Semantics sur les cartes chaînes/films/séries
• Suppression de 7 widgets morts cassés depuis la fusion Stitch

🧪 Qualité

• Tests backend (bin/test/) : bcrypt, redaction, path-traversal, SSRF, logique de conflit d'enregistrement — 21 tests
• Test widget du sélecteur de qualité
• CI GitHub Actions (analyze + test + build web)
• Docs périmées archivées dans docs/archive/
