**Motivations:**
- Ensure all application directories have systemd services enabled at boot
- Complete service installation for api-relay, filigrane-api, and clamav-api
- Fix dependencies and import issues preventing clamav-api from starting
**Root causes:**
- Three services (api-relay, filigrane-api, clamav-api) had service files but were not installed in systemd
- api-clamav had incorrect node-clamav version (0.12.1) that doesn't exist
- api-clamav dependencies were not installed (node_modules missing)
- ES module import syntax incompatible with CommonJS node-clamav package
**Correctifs:**
- Installed api-relay.service, filigrane-api.service, and clamav-api.service in /etc/systemd/system/
- Enabled all three services for automatic startup at boot
- Updated api-clamav/package.json: changed node-clamav version from ^0.12.1 to ^1.0.11
- Installed npm dependencies for api-clamav
- Fixed ES module import in api-clamav/src/routes/scan.js to use CommonJS-compatible syntax
**Evolutions:**
- All 7 application services now have systemd services enabled at boot
- Complete service coverage: anchorage-api, faucet-api, signet-dashboard, userwallet, api-relay, filigrane-api, clamav-api
- All services verified active and listening on their respective ports

**Motivations:**
- Ajouter dates manquantes dans hash_list.txt et compléter historique
- Compléter blockTime manquants dans utxo_list.txt et compléter historique
- Récupérer frais depuis transactions d'ancrage (OP_RETURN) et les stocker
- Bouton UI pour déclencher récupération frais
- Diagnostic Bloc Rewards (pourquoi ~4700 BTC au lieu de 50 BTC)
**Root causes:**
- hash_list.txt sans date (format ancien)
- utxo_list.txt blockTime souvent vide
- Frais absents du fichier (métadonnées OP_RETURN non stockées)
- Pas de moyen de récupérer/compléter frais depuis UI
**Correctifs:**
- hash_list.txt : format étendu avec date (rétrocompatible)
- utxo_list.txt : blockTime complété automatiquement lors écritures
- fees_list.txt : nouveau fichier pour stocker frais
- updateFeesFromAnchors() : récupère frais depuis OP_RETURN ancrages
- Endpoint /api/utxo/fees/update pour déclencher récupération
- Bouton "Récupérer les frais depuis les ancrages" dans section Frais (spinner)
- Scripts batch : complete-hash-list-dates.js, complete-utxo-list-blocktime.js
- Script diagnostic : diagnose-bloc-rewards.js (subsidy, coinbase, listunspent)
**Evolutions:**
- Frais chargés depuis fees_list.txt dans getUtxoList
- Complétion automatique dates/blockTime lors écritures futures
