This commit refines the NIP-17 encrypted messaging implementation with
better relay detection, cleaner UI, and comprehensive documentation.
## Core Fixes
### 1. Fix Missing User Inbox Relays (nip-17-adapter.ts)
- **Problem**: When creating conversations, user's own inbox relays were
only checked from cache, not actively fetched if cache was empty
- **Result**: Send failures with "missing relays" even when relays were
fetched and connected elsewhere
- **Solution**: Actively fetch user's inbox relays if cache is empty,
with fallback to cached value for performance
- **Impact**: Reliable relay detection for sending messages
### 2. Improve View-Only Detection (ChatViewer.tsx)
- **Problem**: Used stale `unreachableParticipants` metadata set at
conversation creation time, causing false warnings even after relay
lists loaded
- **Solution**: Added dynamic `canSendMessage` useMemo that checks
current state of `participantInboxRelays` in real-time
- **Impact**: Send button correctly enables/disables as relay lists load
### 3. Cleaner UI (ChatViewer.tsx)
- Removed large yellow warning banners about view-only mode
- Removed "Sending disabled - waiting for relay lists" text in composer
- Send button now simply disables when relay lists are missing
- **Impact**: Less intrusive, cleaner messaging interface
## Additional Improvements
### Cache Readiness Check (gift-wrap.ts)
- Added `waitForCacheReady()` to prevent race condition on page reload
- Waits up to 1s for encrypted content cache to be accessible before
processing conversations
- **Impact**: Fixes "inbox appears empty" issue on page reload
### Simplified Event Caching (nip-17-adapter.ts)
- Removed redundant `syntheticEventCache` WeakMap
- Uses eventStore as single source of truth with O(1) lookup
- **Impact**: Reduced complexity, eventStore already handles deduplication
### Removed Self-Chat Workaround (nip-17-adapter.ts)
- Deleted 70-line custom gift wrap construction for self-chat
- Applesauce's `SendWrappedMessage` works fine for self-chat
- **Impact**: Cleaner code, better maintainability
### Debug Logging System (dm-debug.ts - NEW)
- Added dedicated DM debug logging utilities
- Enable with: `localStorage.setItem('grimoire:debug:dms', 'true')`
- Levels: dmDebug (verbose), dmInfo (important), dmWarn (warnings)
- **Impact**: Better troubleshooting for NIP-17 issues
### Comprehensive Documentation (docs/gift-wrap-architecture.md - NEW)
- 450+ line architecture document
- Component diagrams, data flow, cache strategy
- Security considerations, performance optimizations
- Debugging guide and testing strategy
- **Impact**: Complete reference for gift wrap implementation
## Testing
- ✅ All tests pass (864 tests)
- ✅ Build succeeds with no errors
- ✅ Lint passes (only pre-existing warnings)
