* Rearrange `Transport`’s properties and functions
* `NostrTransport`: group Transport-related code together
* `BLEService`: group Transport-related code together
* Extract `NotificationStreamAssembler` into a file
* Move private functions to a dedicated extension
* PeerID 14/n: `Transport` and its dependents
* 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.

* QR verification scaffold: add Noise verify payload types, VerificationService with QR schema/signing, placeholder MyQR/Scan views, and UI entry points in header
* QR: fix VerificationQR mutability (sigHex var) and remove duplicate Data hex helpers to resolve redeclaration; wire signed payload assembly
* QR: render actual QR images with CoreImage; add copy button; keep scanner placeholder for now
* QR: fix SwiftUI modifiers — apply .interpolation(.none) and .resizable() to platform Image inside ImageWrapper; remove from wrapper usage
* QR: add iOS camera scanner using AVFoundation; integrate into Scan view; add NSCameraUsageDescription to Info.plist
* QR: make NoisePayloadType exhaustive in ChatViewModel switches by ignoring verifyChallenge/verifyResponse for now (placeholder)
* QR verification: speed + persistence + UX
- Inject live Noise into VerificationService; prewarm QR on app start
- Keep camera active; remove intermediate responder toast
- One-shot/dupe guards and deferred send on handshake
- Persist verified status immediately; standardize fingerprint (SHA-256)
- Show verified badge for offline favorites; mutual verification toast
- VERIFY sheet styling to match peer sheet; UI polish
- Logs to diagnose verified load + favorites mapping

* Refactor: move Nostr embedding and TLVs out of BLE; add NostrEmbeddedBitChat, Packets, PeerIDUtils; centralize MessageDeduplicator; update ChatViewModel to use new helpers; remove AI_CONTEXT.md and CLAUDE.md
* Rename class to BLEService with compatibility alias; move mention parsing out of BLE; emit low-level BLE events to delegate; unify hex helpers; accept 64-hex in isPeerConnected; add PeerIDResolver
* Project: rename file to BLEService.swift and update Xcode project; keep typealias SimplifiedBluetoothService = BLEService for compatibility
* Remove SimplifiedBluetoothService alias; update app code to use BLEService explicitly
* Tests: rename MockSimplifiedBluetoothService to MockBLEService; update typealiases and Xcode project
* Docs: update comments to refer to BLEService (tests, protocol, noise service)
* Tests: rename SimplifiedBluetoothServiceTests to BLEServiceTests; update project references and class names
* Introduce Transport protocol; BLEService conforms; document delegate-only event pattern in BLEService; keep publishers internal for UnifiedPeerService
* Adopt Transport end-to-end: add TransportPeerSnapshot + publishers; BLEService maps to Transport snapshots; UnifiedPeerService consumes Transport; ChatViewModel holds Transport
* Fix Transport integration: replace getPeerFingerprint with getFingerprint(for:); update PrivateChatManager and CommandProcessor to use Transport; add BLEService.getFingerprint(for:); update PeerManager to use Transport
* Refactor transport and BLE/Nostr layers; unify UI events; fix MainActor isolation
- Rename SimplifiedBluetoothService to BLEService and slim responsibilities
- Introduce Transport protocol and peerEventsDelegate for UI updates
- Add NostrTransport and MessageRouter to route PM/read/favorite via BLE or Nostr
- Centralize TLVs, PeerID utils, and MessageDeduplicator outside BLE
- Update UnifiedPeerService and ChatViewModel to use Transport and delegate events
- 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
