* Improve BLE mesh relay and flooding
Add last-hop suppression using ingress-link tracking to prevent echo. Implement deterministic always-relay for handshakes and directed encrypted/fragments; widen jitter for broadcasts; keep TTL cap only for broadcast. Add deterministic K-of-N broadcast fanout to reduce amplification in dense topologies. Introduce backpressure-aware writes using canSendWriteWithoutResponse with per-peripheral queues and draining on peripheralIsReady. Minor helpers for messageID, deterministic selection, and maintenance cleanup.
* Tests: stabilize FragmentationTests and InputValidatorTests
Make _test_handlePacket mark synthetic peers verified/connected with normalized senderID to avoid drops in public-message reassembly tests. Tighten validatePeerID to reject non-hex strings when length equals 16 or 64; allow internal IDs only for other lengths. All iOS simulator tests pass locally.

* Fix warning: remove unused peerNicknames in MeshPeerList
* UI: add 'mention' action in message actions to prefill input with @nick#abcd and focus input
* UX: long-press a message to prefill @mention with sender's full nick#abcd and focus input
* UX: remove long-press mention; add context menu 'Copy message' that copies only the message body (no nick/timestamp)
* Geo teleported: robust tag detection (accept 't', 'teleport', and boolean-like values); mark self on send when tagging; should fix peer list icons

* Mesh robustness: link-aware fragmentation, relay jitter, connection budget, adaptive scanning; fix BLE queue deadlock
- Link-aware fragmentation using per-link write/notify limits
- Directed fragments for one-to-one; exclude from relays
- Add relay jitter with cancel-on-duplicate to reduce floods
- Cap central links and rate-limit connect attempts with queue
- Foreground duty-cycled scanning when connected; continuous when isolated
- Fix deadlock by avoiding sync on BLE queue when already on it
- Silence Keychain var->let warnings
* Mesh: add relay jitter; dynamic RSSI threshold; candidate scoring/backoff; fix misplaced lines in BLEService extension
* macOS UI: restore mesh peer list when geohash feature is iOS-only by moving mesh list outside iOS switch (ContentView)
* ContentView: add macOS mesh peer list under #else to fix missing People section on macOS
* Refactor People section: extract MeshPeerList and GeohashPeopleList into separate views to reduce SwiftUI type-checking complexity; integrate in ContentView
* BLE: prevent re-fragmentation loops; UI: darker mesh blue + first-row spacing in peer list
* Mesh flood/battery: probabilistic relays, adaptive TTL caps, fragment pacing + scan pause, assembly cap; enable relayed DMs with direct-first then flood fallback.
* Refactor BLEService broadcast: split pad policy, encrypted/direct-first handler, and link-aware sender; simplify broadcastPacket to delegate by type.
* Extract relay decision into RelayController with RelayDecision; simplify handleReceivedPacket to use it.
* Move RelayController and RelayDecision into their own file under Services; keep BLEService leaner.

* BLEService: replace Timer with DispatchSourceTimer on bleQueue; NostrTransport: cache placeholder NoiseEncryptionService to avoid reallocation
* Unify peerID validation: InputValidator handles 16-hex, 64-hex, or alnum-/_; NoiseSecurityValidator now delegates to InputValidator
* UI: use standard green for geohash toolbar badge and count (less bright in light mode)
* UI: standardize geohash sheet green to app standard (dark: system green, light: darker green) for buttons and checkmark

* Require signed announces; add Ed25519 key/signature/timestamp TLVs and verify
- Protocol: AnnouncementPacket now requires ed25519PublicKey (0x03), announceSignature (0x04), and announceTimestamp (0x05). Encoder emits, decoder requires; unknown TLVs still tolerated.
- NoiseEncryptionService: add canonical announce sign/verify helpers using context 'bitchat-announce-v1'.
- BLEService: sign Announce, include TLVs; on receive verify (±5 min skew) and ignore unverified; store ed25519 key and isVerifiedNickname in PeerInfo.
- Preserve 8-byte on-wire IDs to keep BLE headers small; no per-message bloat.
* Fix Data.append usage for timestamp bytes in Packets and NoiseEncryptionService (use append(contentsOf:) on UnsafeRawBufferPointer)
* BLEService: fix non-optional announce fields and unwrap signature result; enforce required verification path
* Enforce verified-only public messages; append peerID suffix on nickname collisions in handleMessage
* Suffix duplicate nicknames with peerID prefix in snapshots and getPeerNicknames; ensures lists and messages disambiguate 'jack' vs 'jack'
* Include self nickname in collision detection: suffix remote 'jack' when it matches our nickname in lists and public chat
* UI labels: remove space before '#abcd' suffix in names (public chat, peer lists, snapshots)
* Style '#abcd' suffix light gray:
- Public chat: color suffix in sender via AttributedString segments
- People list: split name and color suffix segment; add helper splitNameSuffix()
* Debounce 'bitchatters nearby' notification: add 60s grace before reset when mesh goes empty; cancel reset when peers return
* Lighten '#abcd' suffix: use Color.secondary.opacity(0.6) in public chat sender and People list
* Toolbar peers indicator: use blue when Bluetooth peers present (was default text color)
* Toolbar peers indicator: use grey when zero peers (was red)
* Toolbar peers indicator: use system grey (Color.secondary) when zero peers, not green
* Fix crash: mutate peripherals dict on BLE queue (not main). Move scan restart to BLE queue as well.
* Reduce connect timeout churn: back off peripherals that time out (15s), increase timeout to 8s, skip non-connectable adverts, and demote timeout log to debug; clean backoff map periodically
* Mentions: support '@name#abcd' disambiguation; filter hashtag/URL styling inside mentions; deliver notifications only to the specified suffixed target when collisions exist
* Fix string interpolation in mention log (escape sequence)
* Mentions: parse '@name#abcd' in sender/receiver; render mention suffix grey (not orange/blue/underlined); ensure receiver notifications trigger for suffixed tokens
* Mentions: include own suffixed token 'name#<myIDprefix>' in valid tokens so '@name#abcd' to self is recognized and notified
* Public actions: show own system message by processing own public messages (remove early-return). Private /hug: add local system message for sender's chat.
* Grammar: change local '/hug' message to past tense ('you hugged/slapped'). Notifications: only fire 'bitchatters nearby' on rising-edge; remove 5-min re-fire and increase empty reset grace to 10m.
* Public /hug echo: add local system message so sender sees action immediately (no reliance on echo)
* Fix visibility: expose addPublicSystemMessage on ChatViewModel and use it from CommandProcessor
* Implement iOS Location Channels (geohash public chats)
- Domain: add ChannelID, GeohashChannel(Level), lightweight geohash encoder
- Identity: derive per-geohash Nostr keys (HMAC-SHA256 device seed)
- Nostr: kind 20000 + #g tag, nickname tag (n), filter helper
- iOS: LocationChannelManager (permissions, one-shot location), Info.plist string
- UI: toolbar # badge (#mesh or #<level>), sheet (irc style, full-row taps, settings link)
- VM: subscribe/send for active channel, clear timeline on switch, nickname cache
- Emotes: route public via Nostr/mesh without echo, local system confirmation, emojis restored
- Haptics: detect hugs/slaps for nickname#abcd and trigger on receiver
- Rendering: remove hashtag/mention formatting (plain monospaced)
Note: iOS-only; macOS unaffected.
* Lifecycle and persistence: resubscribe on foreground/relay connect, cap dedup set, persist mesh timeline.
- ChatViewModel: resubscribe geohash on app foreground and relay reconnect
- Add processed Nostr events cap (2k) with eviction
- Persist mesh public messages in meshTimeline; hydrate on switching to #mesh
- Local geochat messages use nostr: senderPeerID for classification
- Tests: fix JSON contains assertion for #g tag
* Fix Swift 6 concurrency warnings: remove closure-based NC observer, wrap relay reconnect resubscribe in Task @MainActor, resubscribe in appDidBecomeActive selector.
* Location Channels polish: live geohash refresh while sheet open; keep selection stable; toolbar shows #<geohash>; sheet labels show human level + #geohash.
* Add per-geohash in-memory timelines and cap private chats to 1337.
- ChatViewModel: persist geohash messages in geoTimelines[geohash] with cap; hydrate timeline on channel switch
- PrivateChatManager: trim per-peer chats to 1337 on send/receive
- Toolbar badge: prevent wrapping with lineLimit(1)/truncation
* Toolbar badge layout + brand color; Teleport custom geohash; Live refresh uses startUpdatingLocation with significant distance.
- Toolbar: right-justify geohash, head truncation, use brand green
- Sheet: add #custom geohash textfield + join; keep minimal IRClike style
- Manager: startUpdatingLocation()/stopUpdatingLocation() with distanceFilter=250 while sheet is open
* Location sheet live updates: reduce distanceFilter to 21m for more frequent geohash refreshes while open.
* Toolbar badge spacing/width; Sheet: rename to #geohash and button 'teleport'.
- Move # label closer to peer count and widen to avoid truncation
- Change custom field placeholder to '#geohash' and action button to 'teleport' with monospaced font
* Sheet polish: style 'teleport' button with subtle background, disable until valid; prefix '#' label and placeholder 'geohash'; center + style 'remove location permission' and hide separators for these rows. Toolbar: adjust spacing/width for # label.
* Sheet UX: restrict custom geohash input to valid base32 (lowercase, max 12), reduce spacing so placeholder sits closer to '#', add divider under country row, style 'remove permission' and hide row separators as before. Toolbar: minor spacing/width already adjusted.
* Sheet behavior: show channel list even without permission; add green 'get location and my geohash' button; ensure only one separator between country and teleport by removing manual Divider and showing default row separator; refine teleport input filtering and spacing.
* Channel activity nudges: notify after 9 minutes inactivity only in background; triple-tap clear also clears persistent timelines.
- ChatViewModel: track last activity per channel; send local notification when new activity resumes while app in background (with small cooldown)
- CommandProcessor: /clear clears current public channel persistence via viewModel helper
* Fix compile: add activeChannelDisplayName() and clearCurrentPublicTimeline() helpers in ChatViewModel.
* Fix concurrent dictionary access in BLEService.broadcastPacket: snapshot shared collections under collectionsQueue to avoid CocoaDictionary iterator crashes.
* People: channel-aware list and counts
- Sidebar: NETWORK → PEOPLE; removed PEOPLE subheader/icon
- Toolbar: blue #mesh badge; green #<geohash> badge; count color by channel
- Geohash participants: track per-geohash unique senders with 5m decay; publish list
- Update on geohash send/receive; 30s prune timer; channel switch hooks
No changes to mesh peer UX; mesh list retained as-is.
* BLE: snapshot collections for thread-safe access; stopServices uses snapshot; safe characteristic snapshot in broadcast path
LocationChannelsSheet: rename button label to 'remove location access'
* Channel sheet: show current peer counts
- Mesh row shows connected mesh peers count
- Geohash rows show 5m-active participant counts via ViewModel
- Live-updates while sheet is open
* Channel sheet: pluralize counts as 'person/people' in titles
* Geohash sampling: subscribe to all available channels while sheet open
- ViewModel: add multi-channel sampling subscriptions and per-geohash participant updates
- Sheet: start sampling on appear, sync on list changes, stop on disappear
* Channel sheet: render counts '(N person/people)' in smaller font next to label
* Channel sheet: use square brackets for counts and adjust parsing; fix mesh title to '#mesh'
* Geohash DMs: implement send/receive via NIP-17 with per-geohash identity
- NostrEmbeddedBitChat: add no-recipient encoder for geohash DMs
- NostrTransport: add sendPrivateMessageGeohash(using provided identity)
- ChatViewModel:
• startGeohashDM + mapping helpers
• subscribe to per-geohash gift wraps; store DMs in conversations keyed by 'nostr_<prefix>'
• route sendPrivateMessage() for 'nostr_' to Nostr geohash send; local echo and status
• map pubkeys from geohash public events for DM initiation
• resubscribe DM feed on reconnect and channel switch; unsubscribe on leave
- ContentView: long-press 'private message' starts geohash DM when sender is nostr
* Geohash DMs UX: tap participants to DM; support /msg nickname in geohash; DM notifications
- People (geohash) list: bold 'you', sort to top, tap to open DM
- ChatViewModel.getPeerIDForNickname resolves geohash names to nostr_ conv keys
- Geohash DM receive: send local notification when not viewing
* Geohash DMs polish: header title, star hidden, self-DM blocked, message icon, delivered/read ACKs
- Header shows '#<geohash>/@name#abcd' for geohash DMs; hide favorite star
- Geohash people row: add small message icon; prevent self tap
- Prevent sending geohash DM to self
- Send delivery/read ACKs on receive; handle delivered/read to update status
* Geohash DMs: hide encryption status icon in DM header
* BLE: fix data race in broadcast path
- Snapshot peripherals via Array(values) and filter outside sync
- Snapshot subscribedCentrals and centralToPeerID under collectionsQueue
- Mutate subscribedCentrals under collectionsQueue barriers in didSubscribe/unsubscribe
* LocationChannelsSheet: open fully by default (large detent only)
* BLE: remove unused centralMapSnapshot variable
* Geohash DMs: only notify on incoming PM when app is backgrounded; avoid foreground noise
* GeoDM: reliable delivered/read receipts, background-only notifications, and UI tweak
- Implement delivered + read receipts for geohash DMs; send READ on open\n- Handle relay OK acks for gift-wrap sends; resubscribe processes PM/DELIVERED/READ\n- Prevent mesh Noise handshakes for virtual geohash peers (nostr_*)\n- Notify GeoDMs only in background; suppress alerts for already-read msgs\n- Logging: promote key GeoDM receive logs; demote/remove verbose noise\n- UI: remove trailing envelope button from geohash People list
* Fix: remove duplicate variable declarations in AnnouncementPacket.decode()

* Fix fragmentation + BLE long-write + padding
- Accumulate CBATTRequest long writes by offset and decode once per central
- Decode original packet after fragment reassembly (preserve flags/compression)
- Switch MessagePadding to strict PKCS#7 and validate before unpadding
- Make BinaryProtocol.decode robust: try raw first, then unpad fallback
- Unpad frames before BLE notify; fragment when exceeding centrals' max update length
- Skip notify path when max update length < 21 bytes (protocol minimum)
Verified large PMs and announces route without decode errors and peers show reliably.
* Tests: fix weak delegate lifetime, legacy constants, and unused vars; fragment unpadded frames
- BLEServiceTests: hold strong reference to MockBitchatDelegate
- IntegrationTests: fix inline comment braces; replace removed types with test-safe values; use numeric 0x06 for legacy handshake resp checks
- BinaryProtocolTests: remove unused minResult variable
- BLEService: fragment the unpadded frame so fragments are efficient
* tests: add Noise rehandshake recovery test; document in-memory test bus and autoFlood; stabilize large-network broadcast
* tests: align suite with current behavior (compression, padding, routing, nonce); deflake and stabilize

- Fix MainActor isolation: route delegate calls via Task on MainActor; update notifyUI helper
- Adjust related files and tests accordingly
* BLEService: remove internal publishers; switch to delegate-only events
- Drop legacy messages/peers/fullPeers publishers
- Provide lightweight peerSnapshotSubject only to satisfy Transport
- Rework publishFullPeerData to build snapshots from internal state and notify delegate + subject
- Remove all peersPublisher.send call sites
- Keep UnifiedPeerService on delegate updates exclusively
* Remove inlined Nostr send helpers from ChatViewModel; route via MessageRouter
- Replace direct Nostr sends (PM, ACKs, favorites) with MessageRouter
- Add router method for delivery ACKs and implement NostrTransport.sendDeliveryAck
- Simplify ChatViewModel favorite notification path to use router
- Keep Nostr receive handling intact; reduce duplication
* Fix ReadReceipt initializer usage in ChatViewModel (readerID + readerNickname)
* Fix unused variable warning: replace shadowed 'nostrPubkey' bind with boolean check in ChatViewModel
* Fix queued PM format: use TLV for pending messages after Noise handshake
- Pending messages (including first-time favorite notifications) now use the same TLV encoding as normal sends
- Ensures ChatViewModel can decode on first send, even if handshake completes after queuing

* UI: prefer mesh radio icon when connected; map short peer ID to full Noise key; rename ephemeral mapping to shortIDToNoiseKey; ensure header flips to purple globe on disconnect and keeps name.
* chore: stop tracking build artifacts; ignore .DerivedData and .Result*
* logging: add global threshold via BITCHAT_LOG_LEVEL and demote chatty logs to debug; keep critical errors/warnings and key state transitions

Simplified the protocol by removing version negotiation and handshake sequences.
All devices now use protocol version 1 without negotiation. This eliminates
unnecessary connection overhead and complexity while maintaining full
compatibility across the network.
Changes:
- Removed versionHello and versionAck message types
- Simplified connection flow to use announce packets only
- Removed version negotiation state tracking
- Cleaned up handshake timeout logic
- Reduced connection establishment overhead
