jack 4d4c596a17 UI: diversify peer colors; smarter geo notifications; 21m live location
- Use minimal-distance hue palette for mesh and geohash lists; align chat sender colors with list palette.
- Add foreground geo notifications for different channels; deep-link to bitchat://geohash/<gh>; per-geohash 60s cooldown; respect self/blocks.
- Global geohash sampling runs outside the sheet; delegate handles deeplinks and suppresses when already in-channel.
- Switch location channel sheet to continuous CoreLocation with 21m distance filter; add config knob.
- Only link geohash hashtags when standalone (no @name#abcd or word#abcd).
- Include mesh-reachable peers in mesh counts and in "bitchatters nearby" notification.
- Add TransportConfig knobs for palette and geo notifications.

96c6fc0c0d Improve mesh relaying, presence, and DM robustness; signed public msgs; reachability UI; quicker announces; store-and-forward (#527)
* 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.

a7d5b2d7d9 Centralize remaining magic numbers; finalize logging hygiene across UI/BLE/Nostr (#522)
* docs(plans): add refactor plan; chore(config): introduce TransportConfig and use in BLEService/ChatViewModel/PrivateChatManager; feat: add PeerDisplayNameResolver and apply in BLEService; chore: make TransportPeerSnapshot Equatable/Hashable; perf: simplify read-receipt persistence (no synchronize)

* project: add TransportConfig.swift and PeerDisplayNameResolver.swift to iOS/macOS targets (no xcodegen)

* chore: remove unnecessary UserDefaults.synchronize() calls (extension/app/VM)

* project: fix TransportConfig reference path; remove recovered reference; hook correct fileRef in iOS/macOS sources

* chore(BLE): move connect/duty/announce constants to TransportConfig and reference them

* chore(NostrTransport): factor recipient npub resolution into helper; reduce duplication

* chore(BLE): trim raw hex dump on central decode failure to length+prefix

* project: remove duplicate TransportConfig.swift entries from Sources build phases

* chore: centralize more constants in TransportConfig (BLE thresholds, Nostr read-ack, UI caps) and adopt in BLEService/ChatViewModel/NostrTransport

* chore: centralize location + geohash constants (filters, lookback, relay count) and adopt in LocationChannelManager/ChatViewModel

* chore: centralize compression, dedup, verification QR, relay backoff, georelay fetch constants; adopt across modules

* chore: centralize more BLE/Nostr delays; tighten NostrRelayManager logs to concise summaries; adopt config for location/geohash/relays

* refactor(config): centralize remaining magic numbers and finalize log hygiene

Add comprehensive TransportConfig constants for UI, Nostr, and BLE; adopt across ChatViewModel, ContentView, BLEService, ShareViewController, and BitchatApp to remove scattered literals. Standardize Nostr lookbacks/limits, UI delays/animations, and BLE announce/duty-cycle/candidate caps. Preserve behavior while making tuning explicit and safe.

Highlights:\n- UI: animations, scroll throttle, long-message thresholds, batch stagger, color hue tuning, rate-limit buckets, read-receipt debounce, startup delays, share accept/dismiss windows, migration cutoff.\n- Nostr: short display length (8), conv-key prefix length (16), DM lookback (24h), geohash sample lookback/limits; consistent use throughout ChatViewModel.\n- BLE: dynamic RSSI defaults, announce intervals/base+jitter, duty cycles (dense/sparse), fragment/ingress lifetimes, expected write timings/spacing, recent packet window (30s/100), peer inactivity timeout; unified candidate caps (100).\n- Share: use constant dismiss delay; App: use constant share accept window.\n\nRisk/impact: behavior-equivalent with centralized knobs; easier to tune without code edits.

* project: add TransportConfig.swift to Share Extension target to fix build

3c06bd6386 Improve BLE mesh flooding: last-hop suppression, K-of-N fanout, and backpressure (#517)
* 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.

jack acc11101ad Fix geohash linking: avoid links in @mentions
Only link #geohash tokens when not directly attached to an @mention (e.g., @name#gh stays plain). Keeps standalone #geohash tappable.

5fd9140ffa QR verification: live challenge/response over Noise; persistence, offline badges, and UX/perf polish (#510)
* 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

e6903456ab NIP‑17/44: XChaCha20 v2 gift wraps, DM kind=14, receipts + UI fixes (#506)
* NIP-17/44: adopt NIP-44 v2 (XChaCha20-Poly1305, v2: base64url), switch rumor kind to 14, randomize BIP-340 aux; add XChaCha20Poly1305Compat and wire-up

* Nostr DMs: ensure delivered/read acks are sent even without Noise key mapping by falling back to direct Nostr (geohash-style) acks to sender pubkey

* NIP-44 v2 decrypt: try both Y parities for x-only sender pubkeys (even then odd) to fix unwrap authentication failures

* Tests: add NIP-44 v2 ACK round-trip tests (delivered/read) using bitchat1 embedding and gift-wrap decrypt path

* UI: fix DM autoscroll IDs by using dm:<peer>|<id> for private chat item IDs and preserve anchors, ensuring scrollTo targets exist when opening/switching/new messages

* UI: fix string interpolation in DM/geohash context keys (remove escaped interpolation) to resolve 'unused ch' warnings and ensure proper IDs

* UI: MeshPeerList shows transport state icon: radio for mesh-connected, purple globe for mutual favorite/Nostr; fallback dim person for others
