**Motivations:**
- Authors were not being loaded from cache, causing 'Aucun contenu trouvé' message even when authors exist
- useArticles only loaded articles from Nostr subscription, not authors from cache
- Authors should be loaded from cache first (cache-first architecture)
**Root causes:**
- useArticles hook only subscribed to articles from Nostr, not loading authors from cache
- No method to get all authors from cache
- Authors were only extracted from articles returned by subscription, which may not include author presentations
**Correctifs:**
- Added getAll method to objectCache to retrieve all objects of a type from cache
- Modified useArticles to load authors from cache on startup before subscribing to Nostr
- Authors are now loaded from cache and merged with articles from subscription
- totalSponsoring is calculated for each author when loading from cache
**Evolutions:**
- Authors are now available immediately from cache on page load
- Better user experience: no 'Aucun contenu trouvé' when authors exist in cache
- Cache-first architecture: authors loaded from cache before Nostr subscription
**Pages affectées:**
- lib/objectCache.ts
- hooks/useArticles.ts
**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:**
- Language preference was only available in the header via LanguageSelector component
- Language preference was stored in IndexedDB instead of localStorage
- 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
- Added translations for language settings (settings.language.*)

- components/LanguageSettingsManager.tsx (new)

**Motivations:**
- Enable nostrimg.com to see detailed diagnostic logs
- Verify if the issue is code-related or server-side
- Collect logs to diagnose 500 errors
**Root causes:**
- Need to see actual request/response logs to diagnose the issue
**Correctifs:**
- Temporarily enabled nostrimg.com (enabled: true)
- Added comment indicating it's for diagnostic purposes
- Detailed logging already in place to capture request/response details
**Evolutions:**
- None
**Pages affectées:**
- lib/configStorageTypes.ts
**Motivations:**
- Provide clearer error messages when NIP-98 authentication is not available
- Disable nostrimg.com by default since it returns server errors (500)
- Help users understand why nostrcheck.me endpoint is skipped
**Root causes:**
- NIP-98 authentication requires unlocked account but error message was generic
- nostrimg.com endpoint consistently returns 500 errors
- Users don't understand why nostrcheck.me is skipped
**Correctifs:**
- Added detailed error messages for NIP-98 unavailability:
- No account: 'Please create or import an account'
- Account not unlocked: 'Please unlock your account with your recovery phrase'
- Disabled nostrimg.com by default (enabled: false) due to server errors
- Improved console warnings with specific reasons for skipping endpoints
**Evolutions:**
- None
**Pages affectées:**
- lib/nip95.ts
- lib/configStorageTypes.ts
**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:**
- components/KeyManagementManager.tsx
