jackandClaude Opus 4.8 0558c2bc82 Pin announce signing keys to stop mesh identity spoofing
BLE announce trust verified the packet signature against the Ed25519
signing key carried inside the same announce, and the trust policy only
rejected on noise-key mismatch. Since peerIDs derive from the broadcast
(public) noise key, an on-mesh attacker could replay a victim's
peerID+noiseKey with their own signing key, nickname, and a valid
self-signature; the registry/persisted identity was then overwritten
unconditionally, enabling mesh nickname spoofing and forged attribution
of signed public/broadcast messages.

Fix: TOFU-pin the Ed25519 signing key per peer (noise-key-derived
peerID) on the announce path.

- BLEAnnounceTrustPolicy rejects announces whose signing key differs
  from the one already recorded for the peer (.signingKeyMismatch).
- BLEPeerRegistry.upsertVerifiedAnnounce refuses to replace a pinned
  signing key (returns nil) and never drops a pinned key.
- BLEAnnounceHandler falls back to the persisted cryptographic identity
  (persistedSigningPublicKey) when the registry has no signing key, so
  the pin survives registry eviction and app restart.
- SecureIdentityStateManager.upsertCryptographicIdentity refuses to
  replace a persisted signing key with a different one, and the
  cryptographic identities (incl. the pin) now live in the encrypted,
  persisted IdentityCache with synchronous, teardown-safe saves.

Rebased onto main and integrated with #1432 (Noise session identity
binding + signed leaves): both are complementary. #1432's signed-leave
verification reads the same registry/persisted signing key that this
change protects from announce-path poisoning. main's evolution is kept:
BLEPeerRegistry.upsertVerifiedAnnounce still takes capabilities/
bridgeGeohash (nil return propagates as a refusal), the handler's
linkBoundToOtherPeer env is preserved, CryptographicIdentity keeps
main's field set, and EphemeralIdentity uses main's initializer.

6fbf7eee25 Refactor/ble nostr boundaries (#449)
* 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

3ebfa85e90 Feature/nostr embedded bitchat (#448)
* 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
