**Motivations:**
- API d'ancrage retournait une erreur "too-long-mempool-chain, too many unconfirmed ancestors [limit: 25]"
- Les transactions d'ancrage ne pouvaient pas être envoyées au mempool
**Root causes:**
- L'API utilisait des UTXOs non confirmés (confirmations = 0) pour créer les transactions
- Lorsqu'un UTXO provient d'une transaction non confirmée avec des ancêtres, Bitcoin Core limite la chaîne à 25 transactions
- L'appel listunspent utilisait params: [0], récupérant tous les UTXOs y compris non confirmés
- Aucun filtre n'excluait les UTXOs non confirmés
**Correctifs:**
- Changement de listunspent params: [0] à params: [1] pour ne récupérer que les UTXOs confirmés
- Ajout d'un filtre supplémentaire pour exclure les UTXOs avec confirmations = 0
- Amélioration des logs pour indiquer le nombre d'UTXOs non confirmés filtrés
- Ajout d'une gestion d'erreur spécifique pour "too-long-mempool-chain" avec code HTTP 503
**Evolutions:**
- Documentation de la correction dans fixKnowledge/api-anchorage-too-long-mempool-chain.md
**Pages affectées:**
- api-anchorage/src/bitcoin-rpc.js: Filtrage des UTXOs non confirmés, changement minconf de 0 à 1
- api-anchorage/src/routes/anchor.js: Gestion d'erreur spécifique pour too-long-mempool-chain
- fixKnowledge/api-anchorage-too-long-mempool-chain.md: Documentation (nouveau)
**Motivations:**

- Add new services (ClamAV API, Watermark API) to the infrastructure
- Enhance dashboard with new pages and improved functionality
- Improve deployment scripts and service configurations
**Root causes:**
- Missing comprehensive documentation for infrastructure setup
- Need for antivirus scanning service integration
- Need for watermark service integration
- Dashboard required additional pages and features
**Correctifs:**
- Added comprehensive documentation in docs/ (DASHBOARD.md, DOMAINS_AND_PORTS.md, ENVIRONMENT.md)
- Updated systemd service files with proper environment variables
- Enhanced nginx proxy configuration script
- Updated maintenance documentation

- hash_list.txt, utxo_list.txt: Updated with latest data
- anchor_count.txt: Updated anchor count
**Motivations:**
- Fix insufficient UTXO amount error in anchor API
- Ensure continuous availability of usable UTXOs for anchor transactions
- Improve anchor transaction reliability and efficiency
**Root causes:**
- UTXO selection logic was too restrictive, rejecting UTXOs larger than needed
- No automatic provisioning of new usable UTXOs when existing ones were not suitable
- Algorithm prevented efficient use of available UTXOs
**Correctifs:**
- Refactored createAnchorTransaction() to provision 7 UTXOs of 2500 sats on each anchor
- Use single large UTXO to create 1 anchor output + 7 provisioning outputs + change
- Simplified UTXO selection: single large UTXO per transaction instead of multiple small ones
- Added UTXO provisioning logic in signet-dashboard
- Enhanced Bitcoin RPC methods in both api-anchorage and signet-dashboard
- Added documentation in fixKnowledge/api-anchorage-utxo-provisioning.md
**Evolutions:**
- Enhanced signet-dashboard with new pages (hash-list, utxo-list, join-signet, api-docs)
- Improved Bitcoin RPC client with better error handling and UTXO management

- Fix 502 error on dashboard due to service not running
- Add backup script for mining keys and wallet descriptors
- Improve service management with startup scripts and systemd services
**Root causes:**
- dotenv.config() was called without explicit path, causing .env to be loaded from wrong directory
- Services were not started automatically, causing 502 errors
- No backup mechanism for critical keys and wallet data
**Correctifs:**
- Improved .env loading in api-anchorage/src/server.js with explicit path
- Improved .env loading in signet-dashboard/src/server.js with explicit path
- Added backups/ directory to .gitignore to prevent committing sensitive data
- Created export-backup.sh script for backing up mining keys and wallet descriptors
