When the victim has no live link, the replayer's link rebinds to the victim's ID and reads as "connected", and MessageRouter's connected fast-path then trusts it outright: every DM stalls on a Noise handshake the replayer can never complete and is silently lost while showing "sent". Router-level trust gate (no wire change): - Transport gains canDeliverSecurely(to:) — BLE answers with an established Noise session; Nostr keeps its prompt-delivery predicate; the protocol default forwards to canDeliverPromptly for transports without a forgeable link layer. - MessageRouter.sendPrivate only trusts a connected link outright when it can deliver securely; otherwise it still sends (kicking the handshake on a genuine link) but retains a copy and hands a sealed copy to couriers, like the reachable path. flushOutbox gets the same gate so a flush over an insecure link resends instead of dropping the retained copy. Presence hardening (defense in depth): a "direct" announce arriving on a link already bound to a different peer no longer shortcuts the claimed peer into "connected" — only real link state does. Genuine first-contact and direct announces are unaffected; only the ambiguous heal path loses the forgeable shortcut. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * Harden the insecure-link outbox bound; document the second-replay presence gap and the courier metadata tradeoff Review follow-ups on the canDeliverSecurely gate: - flushOutbox no longer counts connected-but-insecure flushes toward the maxSendAttempts drop: the message was actually transmitted over a live link, so a peer whose Noise handshake stalls across reconnect flapping must not burn through the cap and lose the store-and-forward copy the gate exists to preserve. Retention stays bounded by the 24h outbox TTL and the per-peer FIFO cap; acks still clear it. Attempt-counting stays for reachable-only (heuristic) sends. Regression test: >8 connected- insecure flushes keep the retained copy, drop callback never fires. - Document the known second-replay presence gap: linkBoundToOtherPeer reads the binding before rebindLinkAfterVerifiedDirectAnnounce steals the link, so once a first replay has rebound a link to an absent victim's ID, a second replay marks the victim connected. Presence display only — DMs stay on the retain+courier path via the router gate. Not closed at the announce layer because the post-rebind state is indistinguishable from a legitimate rotation/reconnect heal (a supported, field-verified flow). Covered by a two-announce test. - Note the accepted courier-spray metadata tradeoff at the connected- insecure send: nearby verified peers receive a sealed copy (they learn a DM exists, never its content), cleared on ack. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Promote a healed rotation to connected; normalize the secure-delivery probe; retain Codable properties in Periphery Codex review follow-ups on 5017c232: - P1: a legitimate rotation announce necessarily arrives on a link still bound to the OLD peer ID, so the linkBoundToOtherPeer denial stored the new identity as disconnected — and the rebind only fixed link state, never the registry. A healed rotation then read as disconnected until the peer happened to announce again. rebindLinkAfterVerifiedDirect- Announce now promotes the rebound identity to connected after the containment checks pass (registry markConnected + topology/snapshot/ peer-list refresh; the .peerConnected UI event already fired from the announce path). This consciously moves the forged-presence residue from second-replay to first-successful-rebind — bounded by the rebind containment (never steals a live identity, one rebind per link per cooldown) and still display-only: DMs stay gated on canDeliverSecurely. Comments and the pinned tests updated; new regression test covers rotate-on-open-link -> rebind -> isPeerConnected(new) == true. - P2: BLEService.canDeliverSecurely probed the Noise session with the peer ID as given, but sessions are keyed by the short wire ID — a send keyed by the full 64-hex Noise key (favorites resolution) misread an established session as insecure and needlessly retained + couriered every DM until ack. Normalize with toShort() like isPeerConnected. Test drives a real XX handshake and asserts both ID forms pass. - Periphery: the PrekeyBundleStore.StoredBundle.noiseKey "assign-only" flake fired again and slipped past its baselined USR (read exists in loadFromDisk; the indexer intermittently misses it). Replace the baseline entry with retain_codable_properties: true — deterministic, and a truly-dead Codable field is a persisted-format change anyway. Local periphery scan --strict: no unused code detected.

4 people	dd6b624cae	Quality pass on the 1.7.0 batch: fix confirmed bugs, bump to 1.7.1 (#1418) ... * Quality pass on the 1.7.0 batch: fix confirmed bugs, bump to 1.7.1 Post-merge review of PRs #1400–#1417 (push-to-talk, mesh bridging, DM store-and-forward, empty-mesh liveliness, geo-notes). Fixes the confirmed, well-scoped findings; deeper architectural/security items are tracked separately. - PTT hot-mic leak: releasing the mic during VoiceCaptureSession.start()'s 150ms retry pause left the mic live and streaming for up to 120s, because cancel() no-op'd once `completed` was set. Bail after the sleep if the hold was released, and make cancel() always tear down a late-started capture. - Bridge courier depositDrop reported success and burned the dedup slot before the drop was actually published (evicted/compose-fail = lying 📦 "carried" with no retry). Only consume publishedDropKeys on durable accept; add BoundedIDSet.remove() to release evicted/failed slots (uses the dead dedupKey). - Blocked senders resurfaced via archived "heard here earlier" echoes, the one path that bypassed the live block filter — filter at seed time. - A late optimistic .sent clobbered the router's .carried state; extend ConversationStore.shouldSkipStatusUpdate to a full precedence guard (sending < sent < carried < delivered < read). - Read receipts were permanently burned when the router dropped them (marked sent then dropped). sendReadReceipt/routeReadReceipt now return Bool; only record as sent on a successful route, else retry on the next read scan. - MessageRouter.cleanupExpiredMessages() had no production caller, so DMs to a peer that never reconnects sat on .sending until relaunch — run it in the 120s bridge sweep. - Sightings tally now rolls over at midnight while idle; wave notification action localized across all 29 locales; bridged anon#tag uses suffix(4) like everything else; makeThrowawayIdentity delegates to NostrIdentity.generate(); .swiftlint.yml excludes .claude worktrees. - Add regression tests: carried→sent no-downgrade, carried→delivered upgrade, evicted pending drop stays retryable. - Bump MARKETING_VERSION to 1.7.1. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * Fix CI: adjust delivery-status benchmark and drop now-dead addSystemMessage The stricter no-downgrade guard (delivered/carried never regress to sent) broke two things the earlier commit didn't catch locally (perf tests are skipped in the default run, and Periphery runs only in CI): - PerformanceBaselineTests delivery benchmarks alternated sent <-> delivered assuming both directions apply; the delivered -> sent half is now correctly skipped, so the pass measured 0 updates. Alternate two delivered timestamps instead — every update is real, no downgrade. - Routing the geoDM "not in a location channel" error into the thread removed the only caller of ChatPrivateConversationContext.addSystemMessage, leaving it (and its mock) dead per Periphery. Drop the protocol requirement, the mock impl, and the now-vacuous systemMessages.isEmpty assertions (the invariant is compile-time enforced: the context can no longer emit a public system line). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> * Address review findings: read-receipt dedup, carried-vs-sending, block-time echo purge - Read receipts: claim the receipt in sentReadReceipts synchronously before spawning the routing task (chat open runs two read scans in one MainActor stretch, so the async insert let every unread message route twice), and release the claim when the route fails so the retry-on-failed-route behavior is preserved. - Delivery status: extend the no-downgrade guard so the `.sending` stamp a pre-handshake resend emits can no longer clobber carried/delivered/read (the 📦 indicator survived `.sent` but not `.sending`). - Archived echoes: blocking a peer now purges their carried public messages from the gossip archive at block time (UnifiedPeerService and /block), while the fingerprint-to-peerID mapping is still known — the seed-time filter can't resolve offline non-favorite strangers and stays only as defense-in-depth. New Transport hook (default no-op) + GossipSyncManager.removePublicMessages with immediate persist. - Bridge courier: an envelope that can't encode within the drop size caps fails identically on every attempt; consume the dedup slot so the 120s retry sweep stops re-running Noise sealing on it. - MeshSightingsTracker: cache the day-key DateFormatter instead of building one per call. Tests: double-markAsRead dedup + failed-route retry, carried→sending no-downgrade matrix, block-time purge (manager + service wiring), oversize-drop slot consumption. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Also skip the sent→sending downgrade in the delivery-status guard Codex review follow-up: sendPrivateMessage without an established Noise session emits `.sending` asynchronously, so it can land after the message already reached `.sent` and visibly walk "Sent" back to "Sending...". Treat `.sending` as weaker than `.sent` too — the status was already truthful. `.failed` → `.sending` stays allowed so a retry after a real failure remains visible. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Retain Codable properties in Periphery scan (same fix as #1421) The noiseKey assign-only false positive fired persistently on this branch (twice, including a rerun) despite the baselined USR. Byte-identical to the fix on fix/announce-replay-link-steal so the branches merge cleanly in either order.

4 people	74b8a47d02	Empty-mesh liveliness: nearby conversations, echoes, wave, dead drops, radar (#1409) ... * Empty-mesh liveliness: nearby conversations, echoes, wave action, dead drops, radar The empty mesh timeline was a dead end: a grey zero and "nobody in range yet". This turns it into a live surface and gives the app pull when the mesh wakes up: - Nearest conversation: background geohash sampling now tracks actual chat messages (not just presence) per regional channel; the empty state surfaces the busiest nearby conversation with a preview, one tap to join (GeohashChatActivityTracker, fed from GeoPresenceTracker). - Echoes: the carried 6h store-and-forward window renders as dimmed "heard here earlier" rows at launch (new Transport collectArchivedPublicMessages -> GossipSyncManager snapshot, decoded with signature-derived nicknames; content-identity dedup guards against re-synced duplicates). - Wave: the "bitchatters nearby" notification gains a "wave" quick action that broadcasts a mesh 👋 straight from the notification, even backgrounded (first UNNotificationCategory in the app). - Dead drops: /drop pins a note to the current building geohash as a kind-1 location note with a 24h NIP-40 expiry; expired notes are now dropped client-side at ingest; the notices sheet shows "fades in Xh"; a "location notes" toggle plus location-permission controls live in app info (also fixes the duplicated Voice section). - Radar: an ambient sonar animation shows the radio scanning, with a privacy-safe daily tally ("N devices passed within range today" via salted per-day hashes) and a "notes left here" hint that opens the notices geo tab. All new user-facing strings ship in all 29 locales. 1403 tests green, including new suites for the activity tracker, sightings tally, and note expiry/drop publishing. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Review round: app-info polish, urgent/expiry parity, centered radar, pin fill, Codex P2s - App info: LOCATION header uppercased like sibling sections; location notes and live voice descriptions shortened (29 locales); redundant "location access granted" line removed. - Notices parity: urgent + expiry controls now show on the geo tab too; the bridged Nostr note carries ["t","urgent"] and NIP-40 so relay-side readers see both; urgent parsed back from incoming notes. - Radar moved from the top of the empty state to the center of the chat area, below the help text (empty state fills the visible height). - Header pin fills whenever the scope has notices (was: only unseen), and Nostr-only nearby notes now light it too. - Codex P2 fixes: notification completion deferred until the wave action is handled (background suspension dropped the send); NIP-40 notes now prune on a timer when they expire while displayed; the location-notes kill switch retargets the nearby-notes counter immediately. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Hide macOS segmented picker's built-in label in notices composer (duplicate 'expires in') Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Geo notes: permanent (∞) expiry default, urgent stays mesh-only - Geo expiry picker gains ∞ as the default: a permanent note posts as a pure relay note (no NIP-40 tag, no mesh-board copy — a board copy must fade within days, contradicting the ∞ the user picked). 1/3/7d keep the board + bridged-note path with NIP-40. - The notes manager is now owned by the notices sheet (not the list) so the composer local-echoes ∞ notes into the list; it revives via refresh() after a tab-switch cancel, and its expiry-prune timer survives cancel (weak self, dies with the instance). - Urgent toggle returns to mesh-only per review — notes are ambient; the read-side urgent-tag parse stays so tagged notes still render. - macOS: hide the segmented picker's built-in label (duplicate "expires in"). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Clearing the mesh timeline dismisses echoes for good; tighter divider copy Triple-tap /clear emptied the timeline but the next launch re-seeded "heard here earlier" from the persisted archive. A MeshEchoSettings watermark now records the clear; only messages heard after it come back (the archive itself still carries everything for peers' sync). The echo dedup keys reset with it, and panic wipe drops the watermark. Divider copy tightened to "heard here earlier · last 6h" (29 locales). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Echoes visual polish: tinted history block, radar-captioned tally, ambient footer Device-test feedback on the echoes screen: - Archived echoes now sit on a subtle tinted background (secondary at 8%) in addition to the dim, so "heard here earlier" reads as one distinct block; the divider carries the echo ID prefix to join it. - "N devices passed within range today" moves out of the narration lines to sit centered under the radar as its caption. - When the timeline holds only echoes/system lines, a compact ambient footer (small radar + tally + live hints) renders below the history instead of the whole ambient layer vanishing. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Notes strip persists above the mesh chat; leaner empty-state narration - The 📍 "notes left here" line was empty-state-only, so starting a conversation hid it. It is now a tappable strip pinned above the mesh timeline whenever unexpired notes exist at this place (opens the notices geo tab); the nearby-notes counter runs for the whole mesh timeline, not just the empty state. - Empty state narration drops "nobody in range yet..." (the radar and the sightings caption already say it) and the nearby-conversation hint moves below the help line instead of splitting the narration.

4 people	ef848857b7	Remove dead code found by full Periphery audit; add scan config + advisory CI (#1410) ... Periphery 3.7.4 audit of both schemes (macOS + iOS, intersected so platform-specific code is never touched), with test targets indexed and the share extension built. 277 dead declarations removed or demoted: dead forwarding wrappers (ChatViewModel+Nostr/+PrivateChat), removed- feature remnants (autocomplete command suggestions, back-swipe tuning, MediaSendError, GeohashParticipantTracker), unused Tor dormancy bindings, assign-only properties, unused parameters (renamed to _), and redundant public accessibility. 13 orphaned localization keys deleted across all 29 locales (old pre-#1392 location-notes UI, app_info warnings). Two real tests were flagged as unused because they never ran: Swift Testing methods missing @Test (NostrProtocolTests. testAckRoundTripNIP44V2_Delivered, NotificationStreamAssemblerTests. testAssemblesCompressedLargeFrame). Re-armed both; they pass. Deliberately kept, now recorded in .periphery.baseline.json: iOS-only code invisible to the CI macOS scan, C FFI signatures, keep-alive NWPathMonitor reference, InboundEventKey.eventID (dedup semantics), wifiBulk capability bit (reserved for Wi-Fi bulk work, used by BitFoundation package tests), and the String secureClear cluster (exercised by package tests). New: .periphery.yml config and an advisory Dead Code CI job (mirrors the SwiftLint precedent from #1361) that fails on findings not in the committed baseline. Verified: full macOS app suite, BitFoundation (119) and BitLogger (13) package tests green; periphery scan --strict exits clean.

4 people	78a291ab77	Public-mesh push-to-talk: signed live voice bursts in the mesh channel (#1406) ... * Live push-to-talk voice for DMs: stream while you talk, voice note as fallback Holding the mic in a DM now streams AAC frames live over the Noise session (walkie-talkie style, ~0.5s mouth-to-ear at one hop) while recording the same audio as a normal voice note. On release the note ships through the existing fileTransfer pipeline; receivers that heard the live stream absorb it silently into the same bubble (matched by the burst ID embedded in the file name), so reliability comes for free and nobody sees duplicates. Protocol: - NoisePayloadType.voiceFrame = 0x08 carrying VoiceBurstPacket (burstID + seq + START/data/END/CANCELED, length-prefixed AAC frames) - 210-byte burst-content budget keeps each Noise packet inside the 256-byte padding bucket: one BLE frame, never the fragment scheduler - fire-and-forget: frames are dropped (never queued) without an established session; live is only offered when the peer is mesh-reachable Receive: - ChatLiveVoiceCoordinator assembles bursts (jitter-ordered, 0.5s gap skip, 3s idle end, flood/size caps), persists progressively as ADTS .aac so even a partial burst is a replayable bubble - live autoplay only when the conversation is on screen, app active, and the new app-info "live voice messages" toggle is on (also gates live sending) - one-playback-at-a-time via a shared ExclusivePlayback slot Capture: - PTTCaptureEngine taps AVAudioEngine, dual-encodes: live AAC frames + the finalized .m4a (same 16kHz/mono/16kbps settings as VoiceRecorder) - VoiceRecordingViewModel now drives a pluggable VoiceCaptureSession; the composer HUD shows a pulsing LIVE treatment when streaming Includes the push-to-talk design doc, 6 new localization keys across all 29 locales, and unit tests for framing, packetizer budget, ADTS output, codec round-trip, and the assembly/absorb lifecycle. Public-mesh PTT (MessageType 0x29) lands separately on top of this. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Public-mesh push-to-talk: signed live voice bursts in the mesh channel Extends live PTT from DMs to the public mesh timeline. Holding the mic in the mesh channel now broadcasts the burst live as signed voiceFrame packets (MessageType 0x29) while the finalized voice note still ships on release — new clients hear you as you speak and absorb the note silently into the live bubble; old clients (and late joiners) keep receiving the note exactly as before, so mixed-version meshes lose nothing. Wire/relay: - MessageType.voiceFrame = 0x29: ephemeral signed broadcast, never gossip-synced (SyncTypeFlags maps it to no bit), never padded (padding to the 512 block would push every ~490-byte signed packet into fragmentation) - RelayController treats voiceFrame like media fragments: dense-graph TTL clamp contains the sustained ~15 pkt/s per-talker stream, tight 8-25 ms jitter keeps multi-hop latency inside the receiver's 350 ms jitter buffer - inbound gate mirrors public messages: broadcast-only, 30 s freshness cap, packet signature verified against the claimed sender's announce before any audio reaches the UI App: - ChatLiveVoiceCoordinator gains burst scopes: public bubbles land in the mesh timeline, autoplay only while that timeline is on screen, and the finalized-note absorb is scope-bound (a public note can't replace a DM burst or vice versa) - floor courtesy: while someone talks live in the public channel the composer mic tints red and pulses, with an accessibility value naming the talker ("%@ is speaking", localized in all 29 locales); holding still works — a decentralized mesh has no floor arbiter, the tint just discourages talk-over Tests: relay policy (sparse cap + dense clamp), public bubble + talker indicator lifecycle, note absorption into the mesh store, and scope-binding rejection; full suite green (1382 tests). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * PTT follow-ups from review + field test: peer-ID normalization, toggle gates inbound, drop-path diagnostics Codex review fixes (#1403): - makeVoiceCaptureSession normalizes the selected peer with toShort() before the reachability/session checks and binds the send target to that same routing ID — a conversation selected under the stable 64-hex Noise key no longer silently falls back to a classic note while the short-ID session is established - the live-voice toggle now gates inbound bursts too: off means classic-notes-only in both directions (no live bubble, partial file, or early notification; the finalized note still arrives), with a test Field-test diagnostics (first device run: DM frames decrypted but no bubble appeared, with no log evidence of which guard dropped them): - coordinator logs undecodable frames (size + hex prefix) and blocked drops - makeAssembly logs directory/file-handle failures instead of returning nil silently - PTTLiveVoiceSession logs capture start and finish (packet/frame/duration counts); PTTCaptureEngine logs engine start success/failure with the input format; BLEService.sendVoiceFrame logs no-session drops Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Fix iPhone live-capture failure: dead input unit (AURemoteIO -10851, 0 Hz) Field testing showed the phone's live capture failing at mic enable with AURemoteIO -10851 and an input format of 0 Hz / 2 ch — an input unit bound to an earlier (playback-only or settling) audio session. The Mac, which has no session lifecycle, captured fine, which is why public bursts from the Mac worked while phone-side sends degraded from working (first hold) to sporadic to dead across holds. Three layers of defense: - PTTCaptureEngine recreates its AVAudioEngine on every start(), after the session is configured, so the input unit binds to the session that is active now; a dead input (0 Hz or 0 channels) is now a distinct, logged error instead of a silent setup failure - PTTLiveVoiceSession retries the capture start once after a 150 ms route-settle pause - VoiceRecordingViewModel falls back to the classic VoiceRecorder within the same hold if the live engine still cannot start — a route glitch now costs the live stream, never the voice note Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Blue mic when the hold will stream live The mic button now shows readiness at a glance — and doubles as a build marker for device testing: - blue: holding will stream live (DM peer reachable with an established Noise session, or the public mesh channel) - accent (orange in DMs): holding records a classic voice note (no session yet, peer unreachable, or live voice toggled off) - red states unchanged (recording, floor busy) Refactors capture-backend selection into a single liveVoiceTarget() so the indicator and makeVoiceCaptureSession can never disagree. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Revert the blue live-ready mic to the normal accent color The build-verification marker did its job; idle mic color goes back to the accent. The LIVE recording HUD remains the signal for whether a hold is streaming. Keeps the liveVoiceTarget() refactor so backend selection stays in one place. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Leave a trace on every mic press and every inbound-frame drop Field testing read "tap does nothing" as breakage: the mic start is async (permission check + engine spin-up), so releasing before recording begins has always been a silent cancel — for classic voice notes too. Every press now logs which backend it chose and, for quick presses, that it released before recording started. Also logs the two remaining silent drops: inbound voice frames rejected by the live-voice toggle (the one unlogged guard left in the receive path) and the classic-note fallback now includes the toggle state. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Fix mic hold dying instantly in DMs: sheet swipe gesture starved the composer Field logs showed every DM mic hold ending 3-10 ms after it began, on both platforms, while public-channel holds worked — the private sheet wraps its entire content (composer included) in a high-priority swipe-right-to-leave DragGesture, and a high-priority ancestor drag cancels the mic button's press-and-hold within milliseconds. Same starvation mechanism as the DM image-reveal bug (#1402), hitting a drag instead of a tap. The swipe-to-leave gesture now lives on the message list only, so the composer's gestures (mic hold, text field, buttons) are out of its reach and the swipe still works where users actually swipe. Also stops touching the capture engine when a hold cancels before the engine ever started: probing inputNode on a never-started engine instantiates its input unit against whatever session is active and spams benign-but-alarming AURemoteIO -10851 errors into field logs. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Reorder app info sheet: usage first, then settings, then reference New section order: HOW TO USE, then the adjustable bits (appearance, voice, network), then the reference material (features, privacy, symbols legend). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * App info: flow HOW TO USE into one paragraph; "list" and "person" wording The six how-to-use bullets now read as a single comma-separated paragraph (same instruction strings, legacy bullet prefix stripped at render). Two wording updates across all 29 locales: the people icon opens the "list" (not "sidebar"), and you tap a "person's" name (not a "peer's") to start a DM.

Three layers of defense: - PTTCaptureEngine recreates its AVAudioEngine on every start(), after the session is configured, so the input unit binds to the session that is active now; a dead input (0 Hz or 0 channels) is now a distinct, logged error instead of a silent setup failure - PTTLiveVoiceSession retries the capture start once after a 150 ms route-settle pause - VoiceRecordingViewModel falls back to the classic VoiceRecorder within the same hold if the live engine still cannot start — a route glitch now costs the live stream, never the voice note Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> --------- Co-authored-by: jack <jackjackbits@users.noreply.github.com> Co-authored-by: Claude Fable 5 <noreply@anthropic.com>	2026-07-08 09:20:58 +02:00

4 people	f9032cf2b9	Add mesh diagnostics: /ping, /trace, and topology map (#1377) ... * Add mesh diagnostics: /ping, /trace, and topology map - New protocol types ping=0x26 / pong=0x27 (9-byte payload: 8-byte nonce + origin TTL) with per-peer inbound rate limiting (5 per 10s) - /ping @name reports RTT and hop count, 10s timeout - /trace @name prints the estimated path from gossiped directNeighbors - Topology map sheet (circular Canvas layout) reachable from App Info - Ping/pong ride the deterministic directed-relay path like DMs - Tests: payload round-trip, hop-count math, command output, edge normalization, layout Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Fix CI media-wipe race, per-link ping rate limiting, and /ping output routing Three fixes for PR #1377 review: 1. CI flake (sendImage_privateChatProcessesAndTransfersImage): the panicClearAllData / clearCurrentPublicTimeline detached utility-priority tasks delete the real ~/Library/Application Support/files tree, which the test process shares. The wipe fires at a nondeterministic time and raced the sendImage test's JPEG in files/images/outgoing (write then re-read), so prepareImagePacket threw and the test timed out. Both wipes are now skipped under tests (existing TestEnvironment.isRunningTests pattern); this also stops test runs from deleting the developer's real media. 2. Codex P1: ping packets are unsigned, so keying the pong rate limiter on packet.senderID let one connected peer rotate forged sender IDs to bypass the 5-per-10s budget. The limiter now keys on the ingress link (the directly connected peer that delivered the packet); the pong still goes to the claimed sender. Regression test proves rotating senders over one link exhaust one budget (fails 10 vs 5 pongs on the old code). 3. Codex P2: /ping output arrived up to 10s later and was routed from selectedPrivateChatPeer at callback time, misrouting the result after a chat switch. The origin conversation is now captured when the command is issued (CommandOutputDestination) and deferred output is routed there: a DM result lands in the origin chat's history even if deselected, and a mesh-timeline result pins to #mesh instead of the active channel.

4 people	2360140760	Transitive verification: vouch for verified peers over Noise (#1380) ... * Add capability bits to announce TLV Announces now carry an optional capabilities TLV (0x05): a little-endian bitfield with named bits for upcoming features (prekeys, wifiBulk, gateway, groups, board, vouch, meshDiagnostics). Old clients skip the unknown TLV; peers without it decode as nil so features can distinguish "legacy peer" from "advertises nothing". PeerCapabilities lives in BitFoundation with a minimal-length encoding that preserves unknown bits for forward compatibility. Peer capabilities are stored in the BLE peer registry on verified announce and exposed via BLEService.peerCapabilities(_:). The local advertisement set is empty until each feature ships its bit. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Transitive verification: vouch for verified peers over Noise When a Noise session establishes with a peer I verified and that peer advertises the .vouch capability, send signed attestations (up to 16, most recently verified first, at most once per peer per 24h) for the OTHER fingerprints I verified. Receivers accept vouches only from senders they verified themselves, verify the Ed25519 signature against the sender's announce-bound signing key, and surface the result as a new derived trust tier: vouched (unfilled seal) between casual and trusted. Protocol: - NoisePayloadType.vouch = 0x12 carries a batch of TLV attestations: voucheeFingerprint (32B), voucheeSigningKey (32B), timestamp (uint64 ms BE), Ed25519 signature over "bitchat-vouch-v1" | fingerprint | signingKey | timestamp. The voucher is implicit in the authenticated session. - PeerCapabilities.localSupported now advertises .vouch. Storage (SecureIdentityStateManager / IdentityCache): - vouches keyed by vouchee, capped at 8 vouchers each; validity is recomputed on read (voucher still verified-by-me, < 30 days old), so unverifying a voucher retires their vouches without cascade deletes. - New IdentityCache fields are Optional so pre-existing encrypted caches decode cleanly; TrustLevel.vouched is inserted mid-ladder but raw values are strings, so persisted values are unaffected (and vouched itself is never persisted). - Panic wipe clears vouch state with the rest of the identity cache. UI: unfilled checkmark.seal badge in the mesh peer list (filled seal stays exclusive to verified) and a "vouched for by N people you verified" section with voucher names in FingerprintView; VoiceOver labels and xcstrings entries included. Tests: attestation encode/decode + signature (forged/tampered/expired), accept-policy gates, batch cap, trust-level derivation incl. voucher invalidation, persistence compat, and coordinator exchange/accept policies. Full macOS suite: 1088 tests passing. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Fix CI deadlock in vouch tests and live-refresh the fingerprint sheet on vouch acceptance Two fixes for PR #1380 review findings: 1. CI "Run Swift Tests (app)" hang (exit 137): the new SecureIdentityStateManagerVouchTests suite was nonisolated, so Swift Testing ran its tests in parallel on the Swift Concurrency cooperative pool. Each test enqueues a queue.async(.barrier) write (setVerified) and immediately blocks in queue.sync / queue.sync(.barrier) (recordVouch / effectiveTrustLevel). On CI's few-core runners every cooperative-pool thread ended up parked behind a pending barrier that never got a dispatch worker, deadlocking the whole test process until the watchdog SIGKILLed it. The suite is now @MainActor, matching the production isolation of the vouch API (ChatVouchCoordinator is @MainActor) and keeping blocking syncs off the cooperative pool. 2. Codex P2: an open fingerprint sheet did not refresh its vouched badge when a vouch batch was accepted - VerificationModel.bind() never observed the trust-change signal. It now subscribes to the "peerStatusUpdated" notification that ChatVouchCoordinator.notifyPeerTrustChanged() posts (same source PeerListModel uses) and forwards it to objectWillChange. Added a regression test that pins VerificationModel's own subscription (verified to fail without the fix). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Skip media-wipe detached tasks under tests (shared-filesystem race) panicClearAllData and clearCurrentPublicTimeline delete the real ~/Library/Application Support/files tree in detached utility-priority tasks. The SPM test process shares that tree and ChatViewModelTests invoke both methods, so under parallel scheduling the wipe lands at a nondeterministic time — deleting media a concurrently running test just wrote (and the developer's real app data with it). Guard both with the existing TestEnvironment.isRunningTests pattern, mirroring the same fix on feat/mesh-diagnostics (#1377). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Port vouch capability-race fix to feat/vouching (ports b8adcbe9) Ports the on-device-confirmed fix from the integration test branch (commit b8adcbe9) onto feat/vouching so PR #1380 is actually correct. On-device testing confirmed the transitive vouch propagated once the send was triggered on verify / announce arrival rather than auth alone. Vouch attestations only ever sent from peerAuthenticated, gated on the peer's .vouch capability. That capability arrives via the peer's announce, processed independently of the Noise handshake, so at auth time the set was usually empty -> gate failed -> vouch silently skipped and never retried. - Refactor the send path into a reusable attemptVouch(to:fingerprint:now:). - Trigger on peer-list updates (peersUpdated): fired after every verified announce, so the batch goes out once the .vouch bit actually arrives. - Trigger on local verification (vouchToConnectedVerifiedPeers): verifying a peer runs a vouch pass over connected verified peers, covering the verify-while-connected case and propagating the new identity onward. - Relax the capability gate: treat an empty/unknown set as eligible (the Noise 0x12 payload is ignored by non-supporting peers); only skip when a non-empty set explicitly lacks .vouch.

4 people	60be88a4f5	Geohash bulletin board: persistent signed notices over mesh sync (#1379) ... * Add geohash bulletin board: persistent signed notices over mesh sync New MessageType 0x23 carries TLV-encoded board posts and tombstones, self-signed with the author's Ed25519 key ("bitchat-board-v1" / "bitchat-board-del-v1" domains) so notices verify without the author present. BoardStore persists raw signed packets under Application Support/board/ (200 posts, 5 per author, oldest evicted; expiry sweep; tombstones retained until the deleted post's original expiry) and is wiped on panic. Board packets join gossip sync as bit 8 of the existing variable-length types bitfield (a second byte old decoders already accept and ignore), with a 60s round and its own capacity, served straight from the board store so retention has one owner. Posts relay like broadcasts; urgent posts get the announce-class TTL cap. UI: a pin button in the header opens the board for the current channel (geohash board, or mesh-local board), with urgent-pinned newest-first listing, compose with urgent toggle and 1/3/7-day expiry, and swipe-delete on own posts. Geohash posts also publish one-way as Nostr kind-1 location notes when relays are reachable. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Board: bound orphan tombstones and reject future-dated posts at ingest Two hardening fixes from Codex review of the geohash bulletin board: - Orphan tombstones (P1): retention was derived solely from the sender-chosen deletedAt, so self-signed tombstones for unseen post IDs with far-future deletedAt persisted and re-entered sync unboundedly. Retention is now also clamped to receive time (now + 7d + 1h skew -- no post can outlive that), and orphans are capped at 100 globally and 5 per author key with oldest-received evicted first. Matched tombstones and disk restores keep their existing behavior. - Future-dated posts (P2): ingest only checked expiresAt > now, letting posts dated years ahead sort above honest posts and squat the 200 global slots without ever pruning. The single ingest chokepoint (radio, sync, and disk restore all funnel through it) now rejects createdAt > now + 1h skew and expiresAt > now + 7d + 1h skew; the decoder's span rule is unchanged. Adds tests for the skew boundary, far-future expiry, receive-time tombstone clamping, orphan caps/eviction, and matched-tombstone exemption.

4 people	7341696280	Expand store-and-forward: open couriers, spray-and-wait, persistent outbox, 6h public history (#1372) ... Store-and-forward previously delivered to an out-of-range peer only if a mutual favorite happened to be connected at send time and later met the recipient directly, and everything except courier envelopes died with the app process. This closes those gaps end to end: - Persist the MessageRouter outbox to disk, sealed with a ChaChaPoly key held only in the Keychain (no plaintext at rest); queued private messages now survive an app kill and flush on next launch. - Deposit retry: queued messages are re-deposited whenever a new eligible courier connects, tracked per message so the same courier is never double-burned, until 3 distinct couriers carry it or it expires. - Tiered open couriering: signature-verified strangers can now carry mail (2 envelopes/depositor into a 20-slot pool) alongside mutual favorites (5 each); overflow evicts verified-tier mail before favorites'. - Spray-and-wait: envelopes carry a copy budget (4, capped 8, new TLV, wire-compatible with old clients); couriers split half their remaining budget with each newly encountered courier so mail diffuses through a moving crowd. - Remote handover: a verified relayed announce now floods a copy toward the multi-hop recipient (directed-relay treatment, 10-min per-envelope cooldown) while the carried original stays put for a direct encounter. - Public history: gossip-sync window for whole public messages widened from 15 min to 6 h, matched on the receive-acceptance side, and the message store persists to disk so devices bridge partitions and restarts ("town crier"). - Privacy-safe local delivery counters (bare tallies, log-only) so the store-and-forward stack is measurable on-device. - Panic wipe now also clears the sealed outbox, gossip archive, and counters. - Rewrite WHITEPAPER.md to describe the app as implemented (Noise XX/X, actual flood control, courier system, gossip sync, Nostr path); the old document described a bloom filter, three fragment types, and a MessageRetryService that don't exist. 1037 macOS tests pass (17 new); iOS builds.

4 people	a66c591f8e	Courier: deposit in parallel when the only route is a send queue (#1368) ... * Deposit with couriers in parallel when the only route is a send queue The courier path was nearly unreachable: NostrTransport claims any favorite with a known npub as "reachable" regardless of connectivity, and the mesh favorite exchange shares npubs, so for essentially every courier-eligible recipient the router picked Nostr's reachable branch. With no internet the message just sat in the relay send queue — in the flagship scenario (internet shutdown, mutual friend standing right there) the courier walked away carrying nothing. Add Transport.canDeliverPromptly(to:), defaulting to reachability for radio-backed transports; NostrTransport answers honestly by mirroring the relay manager's connection state (fail-closed behind Tor). When the chosen transport can't hand the message off promptly, the router now also deposits a sealed copy with connected couriers. Double delivery is harmless: receivers dedup by message ID, and delivered/read acks never downgrade the carried status. When relays are up, sends are trusted and no courier quota is spent. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Track DM-relay connectivity, not any-relay, for prompt delivery Codex review: NostrRelayManager.isConnected is true when any relay is up, including geohash/custom relays — but private messages target the default (gift-wrap-capable) relay set and queue when none of those are connected. A lone geohash relay would have suppressed the parallel courier deposit while the DM sat in the queue. Publish a DM-scoped connectivity flag and drive canDeliverPromptly from it.

4 people	75da63c9d7	Fix favorites end-to-end: peer-list duplicates, Nostr sync, /fav key corruption (v1.5.4) (#1367) ... * Friend-courier store-and-forward: mutual favorites carry sealed messages to offline peers When a private message has no reachable transport, the router now seals it to the recipient's Noise static key (new one-way Noise X pattern) and hands the envelope to up to three connected mutual favorites. Couriers store the opaque ciphertext under strict quotas (20 total, 5 per depositor, 16 KiB, 24 h) and hand it over when the recipient's announce matches a rotating HMAC recipient tag; the recipient opens it and the message flows through the normal private-message pipeline, so dedup and delivery acks just work. - CourierEnvelope TLV + courierEnvelope (0x04) message type in BitFoundation - Noise X one-way pattern reusing the existing handshake machinery, domain-separated by a courier prologue; sender identity authenticated via the ss DH (no forward secrecy - documented tradeoff) - CourierStore with eviction, file persistence, and panic-wipe integration - Rotating recipient tags (HMAC over epoch day) so carried envelopes don't correlate for observers who don't already know the recipient's key - New "carried" delivery status with figure.walk glyph; header indicator while carrying mail for others - Three-node end-to-end test ferrying packets through real BLEService instances, plus codec/crypto/store/router suites (986 tests green) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Fix courier handoff verification and directed sends * Authenticate courier deposits by ingress peer * Gate courier handover on direct announces and isolate store test Envelopes are removed from the courier store optimistically, so releasing them on a relayed (multi-hop) announce risks losing carried mail to a speculative flood that never reaches the recipient. Handover now also requires the announce to have arrived directly (full TTL), i.e. an actual encounter with a live link; regression test builds a relayed copy of a genuinely signed announce (TTL is excluded from announce signatures). Also make CourierStore's on-disk location injectable so the persistence test round-trips through a temp directory instead of wiping the real Application Support store, and reattach BLEAnnounceHandler's doc comment to the class it describes. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Use Xcode-bundled Swift in CI instead of a standalone toolchain The unpinned setup-swift action installs Swift 6.1, which refuses the SDK on runner images that have rolled to Xcode 26.5 ("this SDK is not supported by the compiler"). Jobs passed or failed depending on which image they landed on. The Xcode-bundled toolchain always matches the image's SDK, and matches local development. Cache keys now include the toolchain version so artifacts from one compiler are never restored into builds with another. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Drop couriered mail from blocked senders at envelope open The UI-layer block check (isPeerBlocked in the transport event coordinator) resolves a fingerprint from the live session or peer list, but a couriered message arrives precisely when its sender is absent — no session, no registry entry — so the check failed open and a blocked identity's mail was delivered anyway. Gate in openCourierEnvelope, where the sealed sender's full static key is in hand. End-to-end test ferries a full deposit→carry→handover round and verifies the envelope from a blocked sender never reaches the delegate (confirmed failing without the gate). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Fix favorites end-to-end: peer-list dedup, Nostr sync, /fav key corruption - UnifiedPeerService: dedup offline favorites against mesh peers by noise key. Phase 2 compared a 64-hex noise-key PeerID against 16-hex mesh IDs (never equal), leaving only a nickname+isConnected heuristic — a mutual favorite that was reachable-but-not-connected or renamed rendered twice, and a same-nick stranger could suppress a favorite entirely. - Nostr inbound: intercept [FAVORITED]/[UNFAVORITED] markers in the live PM handler so they update theyFavoritedUs instead of rendering as chat text; mutual favorites can now form over Nostr. Delete the dead favorite-aware PM variant and ChatNostrCoordinator.handleFavoriteNotification (unwired, parsed a stale FAVORITE:TRUE|… format no sender emits). - NostrTransport.isPeerReachable: match short form regardless of incoming ID width — toggling an offline favorite (addressed by 64-hex noise key) was silently dropped with no reachable transport. - BLEService.sendPrivateMessage: normalize recipient to the short ID like sendFilePrivate, so a 64-hex target hits the existing Noise session instead of initiating a handshake with a 32-byte wire recipient ID. - /fav, /unfav: stop writing Data(hexString: peerID.id) — the 8-byte routing ID for mesh peers — into the favorites store as a "noise key", and stop double-sending the favorite notification; delegate to toggleFavorite with a proper state check. - FavoritesPersistenceService.updatePeerFavoritedUs: keep the stored nickname when the caller passes the "Unknown" placeholder. - Bump marketing version to 1.5.4. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Route DMs to mutual favorites via Nostr when a mesh-keyed peer goes offline Field-tested on device: with a DM window opened while the peer was on mesh (conversation keyed by the short 16-hex ID), walking out of range and sending failed instantly with "peer not reachable" even though the header showed the peer as Nostr-reachable (mutual favorite, npub known). sendPrivateMessage derived the favorites key as Data(hexString: peerID.id) — for a short mesh ID that is the 8-byte routing ID, never the noise key — so the mutual-favorite/Nostr-key checks always came up empty and the send failed before reaching MessageRouter. Conversations keyed by the full 64-hex noise-key ID (opened from the offline favorite row) were unaffected, which is why later tests appeared to work. Resolve the noise key properly (peerID.noiseKey, then the unified peer row, then the favorites store by derived short ID) and add a regression test for the mesh-keyed-peer-goes-offline case. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Label Nostr DMs from favorites with their stored nickname Field-tested: a DM delivered over the Nostr fallback rendered as "anon#678e" instead of the sender's name. The inbound handler named the sender via displayNameForNostrPubkey, which only knows geohash-scoped names — even though the pipeline had already resolved the sender's noise key (the conversation is keyed by it). When the conversation key carries a noise key, prefer the favorite's stored nickname; geohash DMs (nostr_ keys) keep the anon geo name. This also stops an inbound Nostr [FAVORITED] from overwriting the stored nickname with the anon fallback, since the same name feeds updatePeerFavoritedUs. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * Fix courier path for offline favorites addressed by noise-key IDs Two Codex review findings, both the same ID-width confusion this PR targets, in the courier flow: - CourierDirectory.favoritesBacked resolved recipients only via getFavoriteStatus(forPeerID:), which requires a short 16-hex ID — offline favorites are addressed by the full 64-hex noise-key ID, so attemptCourierDeposit silently bailed for exactly the peers couriers exist to serve. The 64-hex ID now yields its own key directly. - openCourierEnvelope emitted the derived short mesh ID even when the sender has no live mesh identity, landing couriered mail in an unresolvable short-ID thread labeled "Unknown". Absent senders now emit the full noise-key ID so the message joins the stable favorite conversation; present senders keep the live short-ID thread.

Key changes: - Add PendingFileManager with configurable limits (max 10 files, 5MB total) - Files auto-expire after 5 minutes if not accepted - LRU eviction when limits are exceeded - Pending files cleared during panic mode (emergencyDisconnectAll) - Add didReceivePendingFileTransfer delegate method - Add acceptPendingFile/declinePendingFile to Transport protocol Security audit reference: Cure53 BCH-01-002 (Medium severity) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>	2026-01-12 10:39:19 -10:00

4 people	40e54a5120	Add voice notes and images over BLE mesh (audio + image only) (#823) ... * Add BLE file transfer support and media UX * Gracefully disable mac attachment pickers in sandbox * Tighten spacing above media message bubbles * Reduce vertical padding between chat rows * Restore iOS file importer for attachments * Copy imported files before sending to preserve access * Allow file transfers from connected but unverified peers * Raise BLE notification buffer cap for large file transfers * Revert "Raise BLE notification buffer cap for large file transfers" This reverts commit b624523af843475db84e4a846db8dcbe824ae408. * Add guard to drop oversized BLE notification assemblies * Let BLE assembler accept large frames up to hard cap * Add detailed logging for BLE fragment assembly * Log incomplete BLE frames for debugging * Stop dropping partial BLE frames while assembling notifications * Fix compressed BLE file transfers * Enable mac attachment importers * Allow mac microphone access * Permit mac media library access * Describe microphone usage * Harden attachment transfer bookkeeping * Display recording milliseconds * Restore mac photo picker access * Use Photos picker on mac * Allow long-press reblur on images * Reblur images via swipe * Lowercase image preview buttons * Keep processed images for outgoing messages * Use save panel for mac image export * Fix image attachment detection * Allow user-selected write access * Align mac image JPEG encoding * Revert unsupported JPEG option * Strip metadata in mac image encoding * Normalize mac JPEG color space * Target image byte size across platforms * Fix CFMutableData handling * Preserve packet version when signing * Use unique transfer identifiers * Stub file transfer methods in mock * Stub file transfer methods in mock * Hide absolute paths in media messages * Resolve image/voice path handling * Fix cleanupLocalFile lookup * Restore BLE broadcasts when notify buffer is saturated * Guard peer map reads on BLE message path * Drop attachment ceilings to 1 MiB and bump release version * Reset BLE assembler on stalled fragment trains * Fix binary protocol test fixtures * Fix critical issues from PR #681 review Critical fixes: - BinaryProtocol: Return nil for unknown versions (prevents buffer underflows) - Add BinaryProtocol.Offsets struct to centralize magic numbers - Replace magic offset calculations with named constants Security/Privacy: - FileAttachmentView: Use url.lastPathComponent instead of url.path (prevents exposing full system paths) Documentation: - Fix compression algorithm documentation (zlib, not LZ4) All tests passing. * Fix UI freeze when receiving voice notes Problem: AVAudioPlayer initialization in VoiceNotePlaybackController.init() was running synchronously on main thread during view creation, blocking UI for 50-200ms per voice note. Solution: - Remove eager preparePlayer() call from init - Load duration asynchronously on background queue - Player is only prepared when playback is actually requested via ensurePlayerReady() This prevents UI freezes when voice notes appear in the chat. * Fix memory leaks and post-playback freeze Fixes: 1. Post-playback freeze: audioPlayerDidFinishPlaying now dispatches to main thread before updating @Published properties (Swift concurrency violation) 2. Unbounded waveform cache: Implement LRU eviction with 20-entry limit - Track last access time for each cached waveform - Evict oldest entry when cache is full - Prevents unlimited memory growth as voice notes accumulate 3. Audio buffer memory leaks: Wrap computeWaveform in autoreleasepool - AVAudioPCMBuffer allocations are autoreleased - Pool ensures buffers are freed promptly 4. Image processing memory: Add autoreleasepool around compression loops - Each jpegData() call creates temporary objects - Inner pool per iteration prevents memory spikes during quality search Memory should now remain stable during extended use. * Eliminate disk I/O from SwiftUI view rendering path Critical performance fix for UI freezes when receiving media: Problem: mediaAttachment(for:) was called during every SwiftUI render, performing synchronous disk I/O on main thread: - FileManager.fileExists() called 2-6x per message (checking subdirs) - applicationFilesDirectory() creating directories on every call - With multiple media messages, this meant 20-100+ disk ops per render Solution: 1. Remove fileExists checks - construct URLs directly - Files are validated during playback/display (fail gracefully if missing) - Sender determines subdirectory (outgoing vs incoming) 2. Cache applicationFilesDirectory() result - Static cache prevents repeated FileManager.url() calls - Directory created only once 3. Remove redundant playback.replaceURL() in VoiceNoteView.onAppear - Controller already initialized with correct URL This eliminates ALL disk I/O from the view rendering hot path. * Cache Nostr identity derivation to prevent crypto during view rendering Critical performance fix: Problem: formatMessageHeader() called deriveIdentity(forGeohash:) during every SwiftUI render for every media message. Each call performed: - Keychain I/O (getOrCreateDeviceSeed) - HMAC-SHA256 computation - Up to 10 secp256k1 key validations (elliptic curve crypto) With multiple media messages, this resulted in 100s of milliseconds of blocking crypto on main thread per render cycle. Solution: Add thread-safe cache for derived identities - Check cache before expensive crypto operations - NSLock protects concurrent access - Identity is deterministic per geohash, so caching is safe This eliminates crypto from the hot rendering path. * Cache geohash identity in ChatViewModel to prevent crypto during rendering Additional optimization for location channels (voice notes are mesh-only, but this helps with text message rendering in geohash channels): - Add cachedGeohashIdentity to avoid deriveIdentity calls during rendering - Check cache before falling back to crypto derivation - Reduces main thread crypto work in location channels * Make voice note loading completely lazy with deferred initialization Aggressive performance optimization to prevent UI freezes: Problem: Even with async loading, creating 10+ VoiceNotePlaybackController instances simultaneously (when scrolling past multiple voice notes) spawned 20+ concurrent background tasks, potentially starving main thread. Solution - Ultra-lazy loading: 1. VoiceNotePlaybackController.init() now does ZERO work - No duration loading - No player creation - Instant initialization 2. Duration loaded on-demand via public loadDuration() method - Called from VoiceNoteView.onAppear after 150ms delay - Reduced priority: .utility instead of .userInitiated - Guard prevents duplicate loading 3. Waveform loading also deferred 150ms - Gives UI time to settle after message appears - Prevents task storms when multiple voice notes appear This spreads the work over time instead of all at once. * Ensure /clear and panic triple-tap delete media files Fix: /clear command and panicClearAllData() now properly delete media files 1. /clear (triple-tap on chat): - Deletes outgoing media (voice notes, images, files) - Conservative: only our sent media, preserves received media - Runs in background to avoid UI freeze 2. panicClearAllData() (triple-tap on bitchat/ header): - Deletes ALL media files (incoming + outgoing) - Removes entire files directory and recreates structure - Ensures complete data wipe for emergency scenarios Both operations run async on .utility queue to prevent blocking UI. * Fix infinite render loop and apply all security fixes CRITICAL BUG FIX - Infinite Render Loop: Root Cause: Duplicate view identity in ContentView.swift:368 ForEach(messageItems) { item in // Already uses item.id via Identifiable messageRow(...) .id(item.id) // ❌ REDUNDANT modifier caused identity re-evaluation loop } When @Published properties updated, SwiftUI re-evaluated .id() → appeared as 'new' identity → triggered re-render → infinite loop. Caused UI freezes, keyboard failures, and 100% CPU usage. Fix: Remove redundant .id() modifier - ForEach already has stable identity. PERFORMANCE FIXES: 1. Waveform Cache Deadlock (Waveform.swift) - Removed nested queue.async(barrier) on cache hits - Was causing task saturation and potential deadlocks 2. Async Send Pattern (ContentView.swift) - Clear input immediately, defer actual send to next runloop - Prevents blocking current event handler 3. Proper Swift Concurrency (VoiceNoteView.swift) - Switch from .onAppear + DispatchQueue to .task - Cleaner async/await pattern for loading 4. Remove Redundant objectWillChange (ChatViewModel.swift) - @Published already triggers updates automatically - Explicit send() was causing double update cycles SECURITY FIXES (C1-C5, H1-H2): C1. Path Traversal Protection (BLEService.swift) - Unicode normalization, null byte removal - Replace ALL path separators, reject dotfiles - Validate paths don't escape directory C2. Integer Overflow (BitchatFilePacket.swift) - Use UInt64 for TLV parsing, safe Int conversion C3. MIME Validation (BLEService.swift) - Whitelist: JPEG, PNG, GIF, WebP, M4A, MP3, WAV, OGG, PDF - Magic byte validation for all types - Lenient on M4A (platform variations) C4. Compression Bomb (BinaryProtocol.swift) - Ratio validation <= 50,000:1 - Defense-in-depth with 1MB size cap C5. TOCTOU Race (ChatViewModel.swift) - Direct removeItem without fileExists check H1. File Size Validation (ChatViewModel, ImageUtils) - Check attributes BEFORE Data(contentsOf:) - Prevents memory exhaustion H2. Metadata Stripping (ImageUtils.swift) - Remove ALL metadata keys from JPEG encoding - Only compression quality set - Protects GPS/EXIF/device info privacy RESULT: ✅ No render loops ✅ Works with Xcode debugger ✅ Voice notes display properly ✅ All security vulnerabilities fixed ✅ 164 tests passing Production ready. * Complete all translations to 100% and fix auto-extraction - Mark non-localizable strings with Text(verbatim:) to prevent extraction - Update UI strings to lowercase per style guide (open, save, close, recording) - Add complete translations for all 29 languages (194/194 strings at 100%) - Remove empty/duplicate entries (@, bitchat/, Open, Recording %@) - Add proper localization comments for all user-facing strings * macOS: Focus message input on launch instead of nickname field * Remove debug print statements from sendMessage * Optimize voice note codec to 16 kHz / 20 kbps for smaller file sizes - Reduce sample rate from 44.1 kHz to 16 kHz (telephony standard) - Lower bitrate from 32 kbps to 20 kbps - Results in ~37% file size reduction (~150 KB/min vs 240 KB/min) - Increases max voice note length from 4.4 to 7 minutes over 1 MiB BLE limit - Maintains excellent voice quality using native AAC-LC codec * Fix critical security issues in fragment reassembly and file cleanup Fragment Reassembly Race Condition (CRITICAL): - Wrap all incomingFragments/fragmentMetadata access in collectionsQueue.sync - Prevents concurrent modification crashes from multi-threaded access - Minimizes lock contention by doing heavy work (reassembly/decode) outside locks - Add upper bound check: reject fragments with total > 10,000 (DoS prevention) - Add cumulative size validation before storing fragments (memory DoS prevention) File Cleanup Path Traversal (CRITICAL): - Use NSString.lastPathComponent to extract filename safely - Prevents directory traversal attacks via malicious filenames - Add path prefix validation before file deletion - Now checks both incoming and outgoing directories (fixes disk leak) Additional Protections: - Fragment assemblies now limited by both count (128) and cumulative bytes (1MB) - Explicit checks for "." and ".." filenames in cleanup - Defense-in-depth: multiple validation layers * Fix post-rebase compilation errors - Remove duplicate NostrIdentityBridge and Bech32 from NostrIdentity.swift (now in separate files) - Add caching to NostrIdentityBridge.deriveIdentity() for performance - Remove duplicate NotificationStreamAssembler from BLEService.swift - Remove duplicate function declarations in BLEService.swift - Remove duplicate DeliveryStatusView and PaymentChipView from ContentView.swift - Fix PeerID type conversions throughout (use .id for String, PeerID(str:) for wrapping) - Update ContentView body to use main's simple VStack structure - Fix NostrIdentityBridge instance method calls - Remove privateChatView (replaced with sheet-based UI in main) Build and tests passing (137/139 tests pass). * Fix remaining compilation issues after rebase - Fix PhotosUI import order (must be after platform imports) - Fix Data.WritingOptions.atomic reference - Add identity derivation caching to NostrIdentityBridge - Fix all remaining PeerID type conversions in ChatViewModel - Fix ContentView body structure to use main's VStack layout - Fix PaymentChipView API usage (now uses PaymentType enum) Build and tests now passing. * Add proper availability checks for PhotosPickerItem PhotosPickerItem requires iOS 16+ / macOS 13+ but canImport(PhotosUI) succeeds on older macOS versions. Add compiler version check to ensure PhotosPicker code only compiles when actually available. This fixes CI build failures on older macOS environments. * Limit PhotosPicker to iOS only to fix CI PhotosPickerItem has SDK availability issues on macOS in CI. Change PhotosPicker from canImport(PhotosUI) to os(iOS) only. macOS users can still import images via file importer (.fileImporter). This is actually cleaner as macOS file picker is more familiar to users. Fixes CI build failures. * Convert new tests to Swift Testing * Fix compilation issue * Add the missing `fileTransfer` case * Explicitly list all Enum cases to get compile-time errors * Revive lost `NotificationStreamAssembler` changes * Allow file fragments to account for protocol overhead * Simplify PR: Focus on audio+image, fix EXIF stripping, remove file transfers - Fix critical EXIF privacy issue in iOS image processing - Both iOS and macOS now use CGImageDestination for metadata stripping - Shared encodeJPEG function ensures no GPS, camera, or metadata leaks - Remove file transfer functionality to simplify PR scope - Deleted FileAttachmentView - Removed sendFileAttachment from ChatViewModel - Removed file picker UI from ContentView - Simplified attachment dialog to image only (iOS) or voice only - Keep focused media features: - Voice recording and playback - Image sending with progressive reveal - Binary protocol for media transfer * Improve camera UX: Direct camera access with camera icon - Change paperclip icon to camera icon for clearer affordance - Open camera directly on tap (no confirmation dialog) - Add CameraPickerView wrapper for UIImagePickerController - Remove PhotosPicker in favor of direct camera access - Images still processed through ImageUtils with EXIF stripping - Accessibility: Added 'Take photo' label * Full-screen camera with photo library option - Change to fullScreenCover for immersive camera experience - Add action sheet with 'Take Photo' and 'Choose from Library' options - Renamed ImagePickerView to support both camera and library sources - Both options open full-screen for better UX - Updated accessibility label to 'Add photo' (more accurate) * Fix camera white bars with overFullScreen presentation - Changed modalPresentationStyle from .fullScreen to .overFullScreen - This should eliminate white bars at top/bottom on notched devices - Explicitly set showsCameraControls and cameraOverlayView for camera mode * Gesture-based photo access: Tap for library, long-press for camera UX improvements: - Tap camera icon → Photo library (common use case) - Long press camera icon (0.3s) → Direct camera (quick photos) - Removed action sheet entirely for cleaner flow - Power users can long-press for instant camera access This is more discoverable and eliminates an extra step in the UI. * Simplify camera presentation to reduce frame errors - Changed back to standard .fullScreen presentation - Removed overFullScreen which was causing frame dimension errors - Let iOS handle safe areas automatically (white bars are intentional) - Reduces gesture gate timeout warnings Note: White bars on notched devices are iOS default behavior for UIImagePickerController. This respects safe areas for status bar and home indicator. True edge-to-edge would require custom AVFoundation camera implementation. * Force dark mode on camera/picker for black safe area bars - Set overrideUserInterfaceStyle = .dark on UIImagePickerController - Changes white bars to black (much better looking) - Camera controls and photo library also appear in dark mode - Consistent dark appearance regardless of system settings * Optimize sheet presentation for camera UI - Force .large detent for maximum height - Hide drag indicator for cleaner look - Use ignoresSafeArea to give camera full space - Should show complete flash button and controls * Fix P1: Add DoS protections to PeerID fragment handler Critical security fix addressing Codex review feedback: The PeerID overload of handleFragment (which is actually called by CoreBluetooth) was missing key safety checks that existed in the String overload: 1. Added total <= 10000 check to prevent unbounded fragment counts 2. Added cumulative size check against FileTransferLimits before storing each fragment 3. Prevents memory exhaustion DoS attacks via malicious fragment streams This ensures the actually-used code path has proper bounds checking. * Fix decompression size limit to support max-sized file transfers Root cause: BinaryProtocol.decode() was rejecting decompressed payloads larger than maxPayloadBytes (1 MB), but TLV-encoded file transfers are slightly larger due to metadata overhead. Fixes: - Changed decompression limit from maxPayloadBytes to maxFramedFileBytes - This accounts for TLV overhead (~50 bytes) + binary protocol headers - Now allows ~1.12 MB decompressed payloads (1 MB + overhead budget) The failing test was: - Creating 1 MB file content - TLV encoding adds ~50 bytes (1,048,627 total) - Compression reduces to ~1,084 bytes (highly repetitive data) - During decode, decompression was rejecting the 1,048,627 byte output - Now correctly allows it since 1,048,627 < 1,179,760 (maxFramedFileBytes) All 154 tests now pass including 'Max-sized file transfer survives reassembly' * Fix critical thread-safety crash in PeerID fragment handler CRITICAL: The PeerID version of _handleFragment was accessing incomingFragments dictionary without collectionsQueue synchronization, causing crashes when multiple BLE threads processed fragments concurrently. Crash stack trace pointed to line 3431 (dictionary subscript) with: 'doesNotRecognizeSelector' - classic concurrent mutation crash. Fix: - Wrapped ALL incomingFragments/fragmentMetadata access in collectionsQueue.sync(flags: .barrier) - Matches the thread-safe pattern used in String version - Separate cleanup into its own barrier block after reassembly - Prevents concurrent dictionary mutations from multiple BLE threads This is the same pattern as the String version (line 1128) which didn't crash. * Remove Localizable.xcstrings formatting noise The Localizable.xcstrings file had massive formatting-only changes (spacing: 'key' vs 'key :') that added 50K+ lines to the PR diff. This was just Xcode reformatting with no actual string changes. Reverted to main's version to keep PR focused on actual code changes. * Add macOS photo picker support - Added MacImagePickerView with NSOpenPanel for macOS - macOS shows photo.circle.fill icon (no camera hardware) - Opens native file picker for images (.png, .jpeg, .heic) - Images processed through ImageUtils with EXIF stripping - Simple sheet with Select/Cancel buttons Cross-platform photo sharing now works: - iOS: Tap for library, long-press for camera - macOS: Tap for file picker * Add Localizable strings for camera and voice features Xcode auto-generated localization strings for new UI elements: - Camera/photo picker labels - Voice recording UI strings - Media attachment descriptions These are legitimate new strings needed for the audio+image feature, not just formatting changes. --------- Co-authored-by: jack <jackjackbits@users.noreply.github.com> Co-authored-by: islam <2553451+qalandarov@users.noreply.github.com>	2025-10-18 20:55:33 +02:00
