**Motivations:**
- User requested spinner during cache update and page reload after completion
- Better UX: visual feedback during update and automatic refresh to show updated data
**Root causes:**
- No visual spinner during cache update operation
- Page was not reloaded after cache update, requiring manual refresh
**Correctifs:**
- Added Spinner component with CSS animation
- Modified button to show spinner during update
- Added page reload using router.reload() after successful cache update
- Wait 1 second after success message before reloading to show feedback
**Evolutions:**
- Better user experience with visual feedback during cache update
- Automatic page reload ensures updated data is displayed immediately
- Spinner provides clear indication that operation is in progress
**Pages affectées:**
- components/CacheUpdateManager.tsx
**Motivations:**
- total_sponsoring should be calculated from cache, not stored in tags
- Author searches should use cache first, not query Nostr directly
- All elements should be read/written from/to database
- Background sync should scan all notes with service='zapwall.fr' tag and update cache
- Sync should run at startup and resume on each page navigation
**Root causes:**
- total_sponsoring was stored in tags which required updates on every sponsoring payment
- Author queries were querying Nostr directly instead of using cache
- No background sync service to keep cache up to date with new notes
**Correctifs:**
- Removed totalSponsoring from AuthorTags interface and buildAuthorTags
- Modified getAuthorSponsoring to calculate from cache (sponsoring queries) instead of tags
- Modified parsePresentationEvent to set totalSponsoring to 0 (calculated on demand from cache)
- Modified fetchAuthorByHashId and fetchAuthorPresentationFromPool to use cache first and calculate totalSponsoring from cache
- Created platformSyncService that scans all notes with service='zapwall.fr' tag and caches them
- Modified _app.tsx to start continuous sync on mount and resume on page navigation
- All author presentations now calculate totalSponsoring from cache when loaded
**Evolutions:**
- Cache-first architecture: all queries check cache before querying Nostr
- Background sync service keeps cache up to date automatically
- totalSponsoring is always calculated from actual sponsoring data in cache
- Better performance: cache queries are faster than Nostr queries
- Non-blocking sync: background sync doesn't block UI

**Motivations:**
- Allow users to set their preferred language (fr/en) in the settings page
- Load language preference from localStorage at startup to configure the application locale
**Root causes:**

- No centralized language settings management in the settings page
**Correctifs:**
- Created LanguageSettingsManager component for settings page
- Migrated language storage from IndexedDB to localStorage for consistency
- Updated _app.tsx to load locale from localStorage synchronously at startup
- Updated useI18n hook to use localStorage instead of IndexedDB
- Updated LanguageSelector component to use localStorage instead of IndexedDB
**Evolutions:**
- Added language preference section in settings page (displayed first)
- Language preference is now loaded at application startup from localStorage

**Motivations:**

**Motivations:**
- Fix import error when importing nsec private keys
- Support both string and Uint8Array formats from nip19.decode
**Root causes:**
- nip19.decode returns decoded.data as Uint8Array, not string
- Validation in KeyManagementManager only checked for string type
- importPrivateKey in keyManagement.ts only handled string type
**Correctifs:**
- Updated KeyManagementManager validation to accept Uint8Array
- Updated importPrivateKey to convert Uint8Array to hex using bytesToHex
- Improved error messages to show actual validation errors
**Evolutions:**
- None
**Pages affectées:**

**Motivations:**
- Provide a dedicated interface for managing Nostr keys
- Allow users to view public keys (npub and hex)

- Respect the existing two-level encryption system
**Root causes:**
- No dedicated interface for key management
- Users need to view their public keys easily
- Users need to import keys in various formats (nsec URL, nsec text, hex)
**Correctifs:**
- None (new feature)
**Evolutions:**
- Created KeyManagementManager component for key management
- Added public key display (npub and hex formats)
- Implemented private key import with support for:
