**Motivations:** - Résoudre erreur "No UTXO large enough" en combinant plusieurs petits UTXOs - Refactorer api-relay avec interface StorageServiceInterface pour meilleure abstraction - Ajouter script restart-bitcoind.sh **Root causes:** - api-anchorage: logique cherchait uniquement un UTXO assez grand, ne combinait pas plusieurs petits UTXOs - api-relay: code dupliqué entre StorageService et DatabaseStorageService **Correctifs:** - api-anchorage: combinaison automatique de plusieurs petits UTXOs si aucun assez grand, ajustement frais pour inputs multiples, limite 20 UTXOs, gestion cohérente verrouillage/déverrouillage **Evolutions:** - api-relay: StorageServiceInterface (abstraction commune), refactoring routes (keys, messages, signatures, metrics, bloom) pour utiliser interface, eslint config, package updates - fixKnowledge: api-anchorage-combine-utxos.md (documentation correction) - restart-bitcoind.sh: script redémarrage bitcoind **Pages affectées:** - api-anchorage: bitcoin-rpc.js - api-relay: eslint.config.mjs, package.json, index.ts, middleware/auth.ts, routes (bloom, keys, messages, metrics, signatures), services (apiKeyService, database, relay, storageAdapter, storageInterface) - fixKnowledge: api-anchorage-combine-utxos.md - restart-bitcoind.sh
