- Mark non-localizable strings with Text(verbatim:) to prevent extraction
- Update UI strings to lowercase per style guide (open, save, close, recording)
- Add complete translations for all 29 languages (194/194 strings at 100%)
- Remove empty/duplicate entries (@, bitchat/, Open, Recording %@)
- Add proper localization comments for all user-facing strings
Fix: /clear command and panicClearAllData() now properly delete media files
1. /clear (triple-tap on chat):
- Deletes outgoing media (voice notes, images, files)
- Conservative: only our sent media, preserves received media
- Runs in background to avoid UI freeze
2. panicClearAllData() (triple-tap on bitchat/ header):
- Deletes ALL media files (incoming + outgoing)
- Removes entire files directory and recreates structure
- Ensures complete data wipe for emergency scenarios
Both operations run async on .utility queue to prevent blocking UI.
Aggressive performance optimization to prevent UI freezes:
Problem: Even with async loading, creating 10+ VoiceNotePlaybackController
instances simultaneously (when scrolling past multiple voice notes) spawned
20+ concurrent background tasks, potentially starving main thread.
Solution - Ultra-lazy loading:
1. VoiceNotePlaybackController.init() now does ZERO work
- No duration loading
- No player creation
- Instant initialization
2. Duration loaded on-demand via public loadDuration() method
- Called from VoiceNoteView.onAppear after 150ms delay
- Reduced priority: .utility instead of .userInitiated
- Guard prevents duplicate loading
3. Waveform loading also deferred 150ms
- Gives UI time to settle after message appears
- Prevents task storms when multiple voice notes appear
This spreads the work over time instead of all at once.
Additional optimization for location channels (voice notes are mesh-only,
but this helps with text message rendering in geohash channels):
- Add cachedGeohashIdentity to avoid deriveIdentity calls during rendering
- Check cache before falling back to crypto derivation
- Reduces main thread crypto work in location channels
Critical performance fix:
Problem: formatMessageHeader() called deriveIdentity(forGeohash:) during
every SwiftUI render for every media message. Each call performed:
- Keychain I/O (getOrCreateDeviceSeed)
- HMAC-SHA256 computation
- Up to 10 secp256k1 key validations (elliptic curve crypto)
With multiple media messages, this resulted in 100s of milliseconds of
blocking crypto on main thread per render cycle.
Solution: Add thread-safe cache for derived identities
- Check cache before expensive crypto operations
- NSLock protects concurrent access
- Identity is deterministic per geohash, so caching is safe
This eliminates crypto from the hot rendering path.
Critical performance fix for UI freezes when receiving media:
Problem: mediaAttachment(for:) was called during every SwiftUI render,
performing synchronous disk I/O on main thread:
- FileManager.fileExists() called 2-6x per message (checking subdirs)
- applicationFilesDirectory() creating directories on every call
- With multiple media messages, this meant 20-100+ disk ops per render
Solution:
1. Remove fileExists checks - construct URLs directly
- Files are validated during playback/display (fail gracefully if missing)
- Sender determines subdirectory (outgoing vs incoming)
2. Cache applicationFilesDirectory() result
- Static cache prevents repeated FileManager.url() calls
- Directory created only once
3. Remove redundant playback.replaceURL() in VoiceNoteView.onAppear
- Controller already initialized with correct URL
This eliminates ALL disk I/O from the view rendering hot path.
Fixes:
1. Post-playback freeze: audioPlayerDidFinishPlaying now dispatches to main
thread before updating @Published properties (Swift concurrency violation)
2. Unbounded waveform cache: Implement LRU eviction with 20-entry limit
- Track last access time for each cached waveform
- Evict oldest entry when cache is full
- Prevents unlimited memory growth as voice notes accumulate
3. Audio buffer memory leaks: Wrap computeWaveform in autoreleasepool
- AVAudioPCMBuffer allocations are autoreleased
- Pool ensures buffers are freed promptly
4. Image processing memory: Add autoreleasepool around compression loops
- Each jpegData() call creates temporary objects
- Inner pool per iteration prevents memory spikes during quality search
Memory should now remain stable during extended use.
Problem: AVAudioPlayer initialization in VoiceNotePlaybackController.init()
was running synchronously on main thread during view creation, blocking
UI for 50-200ms per voice note.
Solution:
- Remove eager preparePlayer() call from init
- Load duration asynchronously on background queue
- Player is only prepared when playback is actually requested via ensurePlayerReady()
This prevents UI freezes when voice notes appear in the chat.

Restructured ContentView layout to prevent sidebar from covering input box
and removed gesture conflicts that caused jitter during slow drags.
Changes:
- Moved sidebar overlay to only cover messages area, not input box
- Input box now always accessible below sidebar (not covered by overlay)
- Removed blocking drag gesture from mainChatView
- Changed sidebar gesture from simultaneousGesture to gesture for priority
- Removed animation-disabling transactions that amplified touch noise
- Removed 2pt threshold checks that caused visible jumps
Result: Send button taps immediately, sidebar slides smoothly without jitter.

The camera scanner was continuously detecting the same QR code (10-30+ times/second), causing multiple verification notifications to be sent. This happened because:
1. AVCaptureMetadataOutput fires repeatedly while QR is visible
2. Each detection triggered a new verification flow
3. After receiving response, pendingQRVerifications was cleared, allowing duplicate scans
Changes:
- Add deduplication using lastValid state to ignore re-scans of same QR code
- Only set lastValid after successful verification initiation
- Add onSuccess callback to close scanner after successful scan
- Automatically return to "My QR" view after verification starts
- Apply same logic to both iOS camera and macOS manual input paths
This ensures exactly one verification request per scan session.

Problem:
- Ghost peers from yesterday appeared on app restart
- Old messages resurfaced after restarting
- Peers running 24+ hours synced stale data to restarting peers
Root causes:
1. GossipSyncManager stored packets indefinitely (no time limit)
2. handleAnnounce/handleMessage had no timestamp validation
3. Relayed announces from other peers could be arbitrarily old
Solution (defense in depth):
- Added 15-minute age window to GossipSyncManager config
- Gossip storage rejects expired packets at ingestion
- Gossip sync responses filter out expired packets
- GCS payload building excludes expired packets
- Periodic cleanup removes expired announcements/messages
- handleAnnounce rejects stale announces before processing
- handleMessage rejects stale broadcast messages before processing
This prevents ghost peers from appearing on restart and ensures
only recent mesh state is synchronized between peers.

* Fix test suite peer ID collisions
Use unique peer IDs for each test suite to prevent global registry
collisions when Swift Testing runs suites in parallel.
- PrivateChatE2ETests: PRIV_* prefix
- PublicChatE2ETests: PUB_* prefix
- Update all peer ID references to use actual instance IDs
This fixes the race condition where simplePublicMessage() was receiving
duplicate deliveries due to registry contamination.
* Add Bluetooth permission & state alerts on launch and foreground
Wire up existing Bluetooth alert infrastructure to show notifications
when Bluetooth is off, unauthorized, or unsupported.
Changes:
- Add didUpdateBluetoothState() to BitchatDelegate protocol
- BLEService now notifies delegate when Bluetooth state changes
- ChatViewModel implements delegate method to show alerts
- Check Bluetooth state on app launch (after 100ms delay)
- Check Bluetooth state when app comes to foreground
- Add getCurrentBluetoothState() method to BLEService
The UI alert already existed but wasn't wired up. Now users will see
appropriate alerts for:
- Bluetooth turned off
- Bluetooth permission denied
- Bluetooth unsupported on device
Alert includes a button to open Settings on iOS.

- Add NetworkActivationService to permit Tor/Nostr only when location is authorized OR at least one mutual favorite exists.
- Gate TorManager.startIfNeeded/ensureRunningOnForeground behind a global allowAutoStart flag.
- Always stop Tor on background for deterministic restarts; rebuild sessions on foreground when allowed.
- NostrRelayManager respects the gate in connect/ensureConnections/subscribe/send/connectToRelay and skips reconnection when disallowed.
- Symmetric shutdown when conditions become disallowed: disconnect relays and stop Tor.
- Fix double-start by avoiding restart if Tor is already ready; prevent background thrash.
- Improve UX: post "starting tor…" via TorWillStart, and "tor started…" on initial ready; keep existing restart messages.
Rationale: Avoid starting Tor/relays when the user has no location permission and no mutual favorites, and ensure a clean, predictable lifecycle (no stale sockets, no double starts).

* UI: replace textual 'close' with X icon\n\n- AppInfoView (iOS): use xmark icon in nav bar to match Location Notes style.\n- LocationChannelsSheet: use xmark icon for close on iOS/macOS toolbars; add accessibility label.
* Location Notes: prefix usernames with @ and lighten #geohash\n\n- Show @ before usernames in notes list.\n- Split header into '@' and '#geohash' and color the geohash with secondary green for consistency.
* Header spacing: add breathing room between channel badge, notes button, and people count\n\n- Add trailing padding after #mesh/#geohash badge.\n- Add leading padding before notes button and people counter to improve readability.
* Header: nudge #mesh/#geohash badge right with leading padding
* Location Notes + Header polish\n\n- Header: add space in '@ #geohash' and use darker green for geohash.\n- Notes list: render '@name#abcd' with darker green for #abcd to match chat.\n- Header: move geochat bookmark icon after #geohash badge with consistent spacing.
* Location Notes: @name regular green, #abcd darker; nudge #hash\n\n- Render '@' and base name in regular green, suffix '#abcd' in darker green.\n- Add extra left padding before '#geohash' in notes header.\n- Increase leading padding for channel badge to push #mesh/#geohash further right.
* Fix notes icon color: subscribe/count at block-level geohash\n\n- Use block (precision 7) geohash for notes: when opening sheet, on channel changes, and when subscribing the counter.\n- Aligns with LocationNotesManager which publishes at street-level geohash, allowing the counter to detect notes and turn icon blue.
* Header spacing: move #mesh/#geohash closer to notes/bookmark\n\n- Reduce trailing padding on channel badge and leading padding on notes/bookmark to cluster them together.\n- Keeps larger gap before people count for readability.
* Notes: standardize on building-level (8 chars) for publish/read\n\n- Use .building geohash when opening notes, reacting to channel updates, and subscribing the counter.\n- Update comments to reflect building-level scope.
* Location Channels sheet: use black sheet background like other sheets\n\n- Add backgroundColor and apply to container and list.\n- Hide list default background with scrollContentBackground(.hidden).
* Notes icon: use green when notes exist (matches app green)
* Location Channels: boxed 'bookmarked' section; keep 'remove location access' outside box\n\n- Wrap bookmarked list in a rounded, subtle grey box within the list.\n- Ensure the 'remove location access' button is not inside the box and clears list row background.
* Notes counter UX: avoid grey flicker when closing sheet\n\n- Preserve last count during resubscribe to prevent brief 0 state.\n- Keep existing subscription when building geohash temporarily unavailable; only cancel if none or permission revoked.
* Notes counter: unsubscribe without clearing count on resubscribe\n\n- Avoid calling cancel() in subscribe; just unsubscribe old sub to prevent wiping count to 0.\n- Prevents green→grey flicker after closing sheet or location updates.
* Notes icon: use sheet count until counter finishes initial load; don’t zero on sheet close\n\n- Compute hasNotes using max(count, sheetCount) while initialLoadComplete is false.\n- Remove sheetNotesCount reset on sheet disappear to avoid transient grey.
* Location Notes header: remove extra gap before #geohash (drop leading padding)
* Notes sheet: color #abcd suffix as darker green via opacity (match chat)
* Notes sheet: show timestamp in brackets; drop #abcd from @name
* chore: commit remaining local changes
* Header: move notes + bookmark to left of #mesh/#geohash
* Header spacing: tighten gap between #mesh/#geohash and peer count

* Location notes: fix duplicate state redeclaration in ContentView
* Location notes: render note bodies with monospaced font in notes list
* Location notes: add close (x) button in sheet header (upper-right) using @Environment(\.dismiss)
* Location notes: acquire geohash on open (force refresh) and show Matrix loader until block-level geohash resolves; add LocationNotesSheet wrapper
* Location notes: inline sheet wrapper to avoid missing file in target; force location refresh and show Matrix loader until block geohash resolves
* Location notes: remove Matrix animation; use simple spinner when acquiring location; simplify notes view layout
* Location notes: remove per-note relative timestamp from sheet (no seconds display)
* Location notes: fix intermittent first load by ensuring resubscribe after geohash change, removing over-eager subscribe guard, and widening note fetch window (no since filter)
* Location notes: add background counter service and show count next to notes icon on mesh; auto-subscribe to current block geohash
* Location notes: move notes icon to the right of #mesh badge in toolbar
* Location notes: restore timestamps in notes list; remove loading state from manager and sheet (no spinner/animation)
* Location notes: drop 'teleport' tag from kind-1 events; simplify note builder API and usage
* Location notes: show timestamp as relative within 7 days, else absolute date (MMM d or MMM d, y); keep monospaced styling
* Location notes: append 'ago' to relative timestamps (within 7 days)
* Switch location notes and UI helpers to building-level geohash (precision 8): add GeohashChannelLevel.building, map length 8, use building for notes selection and counter, add building name mapping
* Location notes: change notes toolbar icon to SF Symbol 'long.text.page.and.pencil'
* Revert notes geohash selection back to block-level (precision 7); keep building level available but unused; update counter and sheet accordingly
* Location notes: show block name (from reverse geocode) in header instead of 'street-level notes'
* Nostr: add EOSE handling with callback support for subscriptions; wire to LocationNotesManager/Counter (initialLoadComplete). Remove 'building' level from channel enum and geocoder mapping; geohash list shows block/neighborhood/city/province/region only
* Fix Swift 6 isolation: hop to @MainActor inside Timer callback for EOSE tracker mutations
* Notes counter: show 0 by default; subscribe at building-level (precision 8) for notes and counter; keep building hidden in channel list
* Notes header: show building name when available (fallback to block name)
* Notes: subscribe counter to building + parent block (merge results); hide notes icon unless location is authorized; replace 10s timer with live location updates while sheet open
* Notes counter: subscribe only to building geohash (precision 8) so count reflects current 8-cell; auto-begin live location refresh on mesh (and permission) to update as you walk
* Notes header: show count in parentheses; icon shows blue if any notes, grey if none; only start live location updates while sheet is open; reduce nickname width; set live distance filter to 10m
* Notes header: show count as '(N note/notes)' with non-bold, secondary styling next to title
* Notes header: move count before title as '<N> note(s) @ #gh'; remove parentheses; keep count non-bold
* Notes header: bold count text; ensure sheet updates when building geohash changes by calling manager.setGeohash on geohash change
* Notes sheet: add light haptic feedback when building geohash changes (iOS only)
* Notes icon: force a one-shot location refresh before (re)subscribing the counter so icon turns blue immediately on current 8-cell
* Notes subscribe: fallback to default relays when GeoRelayDirectory has no entries (pass nil relayUrls) so counter/icon turn blue and sheet loads even before georelay fetch
* Notes icon: turn blue immediately when sheet shows notes by passing count up from sheet (closure) and OR-ing with counter; reset on sheet close

* Fix emote targeting and grammar; add tests
Prevent 'system' mis-target via peerID-derived display name in actions sheet. Correct /hug and /slap usage/error grammar by passing base command name. Improve geohash nickname resolution to match displayName with #suffix. Add CommandProcessor tests.
* Geohash ordering: strict in-order inserts and timestamp clamp
Use channel-aware late-insert threshold with 0s for geohash to keep strict chronological order. Clamp future Nostr event timestamps to 'now' to avoid future-dated items skewing order in geohash timelines.
* Trim trailing/leading spaces in geohash nicknames and tag emission
Sanitize Nostr 'n' tag values on ingest and emit by trimming whitespace/newlines to prevent trailing spaces in displayed usernames. Local nickname is already trimmed on focus loss and submit.
