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.

* Sign public broadcasts; verify relayed messages via persisted signing keys; keep scheduled relays in sparse graphs and speed their jitter; persist announce signing key for offline auth; add short backoff after disconnect errors to reduce reconnect thrash
* Add connected vs reachable model: retain peers after link drop, expire after reachability window; expose all peers in snapshots; compute isReachable in UI; add meshReachable state and sorting; avoid removing peers on link events; notify UI on stale removals
* ContentView: handle new .meshReachable connection state in header icon switch (exhaustive switch fix)
* Logs: tag relayed announces as 'Reachable via mesh' and annotate public message logs with (direct|mesh) path for easier field analysis
* Fix syntax error: remove stray else/log inserted into writeOrEnqueue; keep logs clean
* UI: use 'point.3.connected.trianglepath.dotted' for mesh-reachable; change people count to include connected+reachable (exclude Nostr-only)
* UI: switch to 'point.3.filled.connected.trianglepath.dotted' for mesh-reachable icons in list and header
* Reachability: reduce retention to 21s for all peers (verified and unverified) to minimize stale presence
* mesh DMs/acks: route to reachable peers; queue READ/DELIVERED until handshake; add Transport.isPeerReachable; UI: hide offline non-mutuals; DM header: better name fallback + show transport + encryption icons; fix NostrTransport conformance
* Verification sheet: compute encryption status and fingerprint using short mesh ID mapping (fix 'not encrypted/handshake' for DMs with stable key)
* Announce cadence: faster discovery (4s), sparse 15±4s, dense 30±8s; initial 0.6s; post-subscribe 50ms; min-force 150ms; maintenance 5s; proactive announces on handshake + recent-traffic nudge
* Relay: increase broadcast TTL cap in sparse graphs to 6; tighten jitter for handshake (10–35ms) and directed (20–60ms) relays
* Range/robustness: store-and-forward for directed packets (15s) with flush on new links + periodic; announces: no subset + afterglow re-announce on first-seen; adaptive scanning: force ON when <=2 neighbors or recent traffic
* Fix warnings: remove unused msgID and unused mutable var in directed spool flush
* Announces: TTL 7 (sparse only) via RelayController; no fanout subset for announces; neighbor-change rebroadcast of last 2–3 announces. Fragments: faster pacing (5ms global, 4ms directed).
* Peer list: real-time icon updates by publishing snapshots on connectivity checks; add unread message indicator (envelope) next to peers with unread DMs
* UI: unread envelope uses orange; hasUnreadMessages checks Nostr conv key for peers with known Nostr pubkeys (geohash DM consistency)
* Logs/robustness: debounce disconnect notifications (1.5s), debounce 'reconnected' logs (2s), add weak-link cooldown after timeouts on very weak RSSI (<= -90)
* Peer icons: faster, accurate reachability\n\n- Run connectivity checks every maintenance tick (5s)\n- Publish peer snapshots on central unsubscribe for instant UI refresh\n- Lower inactivity timeout to 8s and disconnect debounce to 0.9s\n- Gate reachability on mesh-attached (>=1 direct link); no links => no reachable peers\n- Keep 21s retention for verified/unverified, but only when attached to mesh\n\nImproves list responsiveness when walking out of range and prevents stale 'reachable' states when isolated.

* 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.

* 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
* use noise pubkey wip
* ttl=0 for signatures
* verification works

* 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
