**Motivations:**
- Export Signet and mining wallet backups to git with only 2 versions kept
- Document and add backup/restore scripts for signet and mining wallet
**Correctifs:**
- Backup-to-git uses SSH URL for passwordless cron; copy timestamped files only; prune to 2 versions; remove *-latest from backup repo
**Evolutions:**
- data/backup-to-git-cron.sh: daily export to git.4nkweb.com/4nk/backup
- save-signet-datadir-backup.sh, restore-signet-from-backup.sh, export-mining-wallet.sh, import-mining-wallet.sh
- features/backup-to-git-daily-cron.md, docs/MAINTENANCE.md backup section
- .gitignore: data/backup-to-git.log

**Motivations:**
- Anchor API requests were timing out with "This operation was aborted" errors
- Multiple simultaneous anchor requests can wait for mutex, causing delays
- Slow Bitcoin RPC calls can exceed the 120s timeout
**Root causes:**
- Timeout of 120s was too short when multiple anchors are in progress (mutex wait)
- Slow Bitcoin RPC operations (listunspent, createrawtransaction, sign, send) can take longer than 120s
- Insufficient logging made it difficult to diagnose timeout vs connection closure
**Correctifs:**
- Increased ANCHOR_API_TIMEOUT_MS from 120000 (120s) to 180000 (180s) to handle mutex waits and slow RPC calls
- Added start time tracking to measure elapsed time for all operations
- Enhanced logging with:
- Log at request start with url, documentUid, hash (truncated), timeoutMs
- Log on success with txid and elapsedMs
- Log on abort with elapsedMs, timeoutMs, errorName, errorCode
- Log on failure with elapsedMs, errorName, errorCode
- Improved error message to include elapsed time: "timeout or connection closed after Xs"
- Added timeout-specific log when timeout is reached (before abort)
**Evolutions:**
- Better observability with elapsed time in all logs
- More detailed error information (errorName, errorCode) for diagnosis
- Timeout log helps distinguish timeout from early connection closure
**Pages affectées:**
- api-filigrane/src/routes/watermark.js: Increased timeout, added timing and enhanced logging
- fixKnowledge/api-filigrane-anchor-request-aborted.md: Updated documentation with new timeout (180s), improved logging details, and mutex wait explanation
**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
