Remove dead code found by full Periphery audit; add scan config + advisory CI (#1410)
Periphery 3.7.4 audit of both schemes (macOS + iOS, intersected so platform-specific code is never touched), with test targets indexed and the share extension built. 277 dead declarations removed or demoted: dead forwarding wrappers (ChatViewModel+Nostr/+PrivateChat), removed- feature remnants (autocomplete command suggestions, back-swipe tuning, MediaSendError, GeohashParticipantTracker), unused Tor dormancy bindings, assign-only properties, unused parameters (renamed to _), and redundant public accessibility. 13 orphaned localization keys deleted across all 29 locales (old pre-#1392 location-notes UI, app_info warnings). Two real tests were flagged as unused because they never ran: Swift Testing methods missing @Test (NostrProtocolTests. testAckRoundTripNIP44V2_Delivered, NotificationStreamAssemblerTests. testAssemblesCompressedLargeFrame). Re-armed both; they pass. Deliberately kept, now recorded in .periphery.baseline.json: iOS-only code invisible to the CI macOS scan, C FFI signatures, keep-alive NWPathMonitor reference, InboundEventKey.eventID (dedup semantics), wifiBulk capability bit (reserved for Wi-Fi bulk work, used by BitFoundation package tests), and the String secureClear cluster (exercised by package tests). New: .periphery.yml config and an advisory Dead Code CI job (mirrors the SwiftLint precedent from #1361) that fails on findings not in the committed baseline. Verified: full macOS app suite, BitFoundation (119) and BitLogger (13) package tests green; periphery scan --strict exits clean.

Remove abandoned peer ID rotation code: - Remove previousPeerID property and rotationGracePeriod constant - Remove grace period logic from isPeerIDOurs() - Remove previousPeerID handling from announce packets - Pass nil for previousPeerID in identity announcements Phase 2 - Fix ghost connections from relayed packets: - CRITICAL FIX: Only add peers to activePeers if they have a peripheral connection - Check for peripheral connection before marking peer as active - Prevents ghost connections when announce packets are relayed - Log warning when rejecting relayed announce without peripheral Phase 3 - Begin consolidating redundant peer tracking: - Create new PeerSession class to unify peer data in one place - Add helper methods for PeerSession management - Integrate PeerSession into announce packet handling - Update authentication state changes to use PeerSession - Update peripheral mapping and RSSI to sync with PeerSession - Update disconnect and leave handling to update PeerSession - Add consolidated getter methods for peer info This fixes the issue where peers appeared connected without actually having a Bluetooth connection, and begins the migration to a cleaner single-source-of-truth peer tracking system. * Fix multiple connect messages on peer restart - Move hasPeripheralConnection check outside sync block to fix scope issue - Add debug logging to track connect message conditions - Ensure connect messages only show on first connection or reconnection with peripheral * Optimize RSSI updates for better battery life -

Update FavoritesPersistenceService to notify with both old and new keys - Handle peer ID changes in ChatViewModel to migrate private chat data - Update selectedPrivateChatPeer when favorite's noise key changes - Maintain chat history and unread status across peer ID changes * Fix read receipts after peer reconnection and replace nos.lol relay - Updated sendReadReceipt to resolve current peer ID when peers reconnect with new IDs - Enhanced MessageRouter to check favorites for current noise keys - Replaced nos.lol relay with relay.snort.social to avoid PoW requirements * Fix message routing to use Nostr when peers are disconnected Changed message routing logic to check actual peer connection status using isPeerConnected() instead of just checking if peer exists in nickname list. This ensures that offline mutual favorites correctly route messages through Nostr instead of attempting Bluetooth handshakes. Also added safety check to prevent starting private chat with ourselves. * Add debug logging for Nostr timestamp randomization Added logging to track the random offset being applied to Nostr event timestamps to debug why messages appear 8-9 minutes in the future. * Fix Nostr timestamp issue by reducing randomization range Temporarily reduced the timestamp randomization from +/-15 minutes to +/-1 minute to address messages appearing 8-9 minutes in the future. Added detailed UTC/local time logging to help debug the issue. The random offset should have been evenly distributed but was consistently showing positive offsets. This change mitigates the issue while we investigate the root cause. * Fix message routing for offline favorites and reduce Nostr timestamp randomization - Fix transport selection to properly detect disconnected peers using isPeerConnected() - Change from checking peer nicknames to checking actual connection status - Reduce Nostr timestamp randomization from ±15 minutes to ±1 minute - Add detailed timestamp logging for debugging * Improve PM header UI and encryption status display - Show transport icons (radio/link/globe) in PM header matching peer list - Always show lock icon if noise session ever established (no handshake icon) - Change verified icon from shield to checkmark seal - Use consistent green color (textColor) for PM header and encryption icons * Update AI_CONTEXT.md with comprehensive Nostr implementation details - Add Nostr and MessageRouter to architecture diagram - Document NIP-17 gift wrap implementation - Explain favorites integration and mutual requirement - Detail message routing logic and transport selection - Add security considerations and debugging tips - Update common tasks with Nostr-specific guidance * Fix data consistency issues in favorites, chat migration, and bloom filter - Fix favorites deduplication to use public key instead of nickname Prevents losing favorites when multiple peers use same nickname - Fix private chat migration to use fingerprints instead of nicknames Prevents merging unrelated conversations that share nicknames Fallback to nickname matching only for legacy data without fingerprints - Fix bloom filter reset to preserve messages from last 10 minutes Prevents duplicate message processing after bloom filter resets Keeps processedMessages for 10 minutes while bloom filter resets every 5 * Add mutual favorites internet messaging to app info * Remove excessive debug/info logging for production readiness - Removed ~140 debug/info level logs across core services - Preserved critical logs: errors, warnings, security events, state changes - Kept logs for: peer join/leave, favorite status, mutual relationships - Cleaned up verbose logging in: Bluetooth mesh, Nostr, message routing - Improved performance by reducing log I/O overhead 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> * Implement performance optimizations and fix build warnings - Add UI update debouncing (50ms) to prevent excessive SwiftUI refreshes - Implement memory bounds for processedMessages with LRU eviction - Add encryption queue cleanup for disconnected peers - Optimize peer lookups from O(n) to O(1) with indexed dictionary - Fix multiple compiler warnings (unused variables, missing break statements) - Optimize peer counting with single-pass reduce operation - Fix ViewBuilder control flow issue in ContentView - Fix Dictionary initialization type mismatches with Array wrapper * Add TTL-based cleanup for Noise handshake sessions - Add session TTL (5 minutes) and max session limit (50) to NoiseHandshakeCoordinator - Clean up old established sessions to prevent unbounded memory growth - Move handshake cleanup timer out of DEBUG conditional for production use - Run cleanup every 60 seconds in production (vs 30s in debug) - Clean up crypto state immediately on peer disconnect - Prevents memory leaks from accumulating Noise sessions * Pre-compute and store fingerprints in PeerSession for O(1) lookups - Store fingerprint in PeerSession when peer authenticates - Update getPeerFingerprint() and getFingerprint() to check PeerSession first - Replace all noiseService.getPeerFingerprint() calls with optimized version - Eliminates repeated SHA256 calculations during message processing - Improves performance for favorite checks and encryption status updates * Implement exponential backoff for Nostr relay connections - Add reconnection tracking fields to Relay struct (attempts, timing) - Replace fixed 5-second delay with exponential backoff (1s → 2s → 4s... max 5min) - Stop reconnection attempts after 10 failures to prevent infinite retries - Reset attempt counter on successful connection - Add utility methods: retryConnection(), getRelayStatuses(), resetAllConnections() - DNS failures still bypass retry logic as before - Improves battery life and reduces server load from constant reconnection attempts --------- Co-authored-by: jack <jackjackbits@users.noreply.github.com> Co-authored-by: Claude <noreply@anthropic.com> |
