**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
**Pages affectées:**
- api-clamav/package.json
- api-clamav/src/routes/scan.js
- api-clamav/node_modules/ (new)
- api-clamav/package-lock.json (new)

- /etc/systemd/system/clamav-api.service (new)
**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

**Motivations:**
- Complete documentation for dashboard, domains, ports and environment configuration
- 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
**Evolutions:**
- Added new ClamAV API service (api-clamav) for file scanning
- Added new Watermark API service (api-filigrane) for document watermarking
- Enhanced signet-dashboard with new learn.html page
- Improved dashboard UI with better styles and navigation
- Enhanced app.js with new functionality and better error handling
- Updated API documentation page with complete endpoint descriptions
- Added deployment scripts for watermark and nginx configuration
- Updated hash and UTXO lists with latest data
- Enhanced server.js with new routes and improved Bitcoin RPC integration

- 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
- Added cache files for hash and UTXO lists
- Updated api-faucet with improved server configuration
