From 7bc566fa006fd0b7230766dfcb3df1d98f9e8683 Mon Sep 17 00:00:00 2001 From: "torlando-agent[bot]" <281092095+torlando-agent[bot]@users.noreply.github.com> Date: Tue, 2 Jun 2026 10:52:25 -0400 Subject: [PATCH 01/52] feat(identity): shared keychain access-group for app<->NE identity (Track A3) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Model B's Network Extension must load the SAME RNS identity as the app to sign delivery proofs / decrypt inbound LXMF while the host is suspended. Add a shared keychain group: - Both target entitlements declare keychain-access-groups = [$(AppIdentifierPrefix)network.columba.Columba.shared]. - Identity.save/load/deleteFromKeychain take an optional accessGroup (kSecAttrAccessGroup); existing callers default to nil (behavior unchanged). - AppServices resolves the group at runtime (team-id prefix probed from the keychain, never hardcoded — no deployment PII), threads it through loadOrCreateIdentity, and migrates a legacy default-group identity into the shared group on first launch. Accessibility stays AfterFirstUnlockThisDeviceOnly (NE-readable while locked; no backup/sync). - The unencrypted identity.key fallback is neutralized: removed once the keychain holds the identity, and otherwise written with CompleteUntilFirstUserAuthentication protection. Builds Columba-Swift green. Cross-process keychain sharing is entitlement-enforced only on a signed build — device-verified with the NE wiring (A5/Track C).

Repoint MessageRepository to the GRDB store, keeping every public method returning RNSAPI types via pure static adapters, so the UI/ViewModels are unchanged. Architecture: `import LXMFSwift` is confined to MessageRepository.swift (the adapter boundary). AppServices/ColumbaApp/MapView stay RNSAPI-typed and pass only a String path — they do NOT import LXMFSwift (it transitively exposes ReticulumSwift, whose names collide with RNSAPI's Compat layer; a prior attempt that imported it into AppServices was reverted). AppServices routes Python-path inbound-persist + delivery-state through MessageRepository's RNSAPI-typed methods; the Swift backend's LXMRouter already persists to GRDB itself. Adapters map ConversationRecord/MessageRecord/IconAppearance/LXMessage + state/method enums (Date<-Double, enum<-Int, String<-String?); LXMessage bridges via the LxmfFieldCodec field-map. Tests: MessageRepositoryAdapterTests — TEST SUCCEEDED on iPhone 17 sim; builds green. KNOWN FOLLOW-UPS (tracked — do not lose): 1. IncomingMessageHandler (block_unknown_senders favorite-check, senderIsFavorite) and NotificationService (sender displayName) still read the now-empty Compat `db` — must repoint to the GRDB MessageRepository. block_unknown_senders is off-by-default (low impact) but notification sender-name + favorite gating degrade until fixed. (Next commit.) 2. NE/Swift-backend rows store the full LXMF wire in packed_lxmf while app-written rows store the field-map; LxmfFieldCodec.unpack returns nil on wire bytes, so attachments/icons on NE-delivered rows won't render (text/state/timestamp/direction map fine). Needs a wire-unpack path in the adapter, or the NE storing the field-map.

Add the bridge primitives: - SharedFrameQueue is now bidirectional: e2a ("frame_queue", NE->app, #57-compatible default) + a2e ("frame_queue_a2e", app->NE radio ingest), each with its own backing file + lock. FrameInterfaceTag gains .bleMesh/.rnode; radioFrameReadyNotificationName (app->NE) added. - AppGroupBridgeInterface (actor) conforms to ReticulumSwift.NetworkInterface: send() HDLC-frames + enqueues to e2a + posts the Darwin notification; setDelegate() stores a weak delegate; deliverInbound() fires didReceivePacket for app->NE frames. mode=.full (announces propagate both ways); hwMtu = the radio's negotiated MTU. Collision-safe: the bridge file imports only ReticulumSwift + Foundation (NOT RNSAPI, whose Compat layer re-declares NetworkInterface). The NE target doesn't link ReticulumSwift yet, so the file is in the ColumbaApp target only; A5/C2 add it to the NE once the NE runs the Swift backend. Registration into the NE transport + the app-side radio relay loop are A5. Columba-Swift builds green. Runtime (NE using the bridge) is exercised in A5 on-device.

Promote it to the backend-neutral RnsCore protocol so both backends answer truthfully: - RnsCore gains `func registeredDestinationHashes() async -> [String]` (lowercase-hex). - SwiftRNSBackend returns the lxmf.delivery + lxst.telephony Destination hashes it registered in start() ([deliveryDestination, telephonyDestination].compactMap { $0?.hexHash }). - PythonRNSBackend returns the cached delivery hash (localInfo.destinationHash); telephony isn't surfaced by the Python bridge's LocalInfo — documented, true subset (delivery is the LXMF-inbound hash the NE filter needs). - AppServices diagnostic dump rewired from the dead Compat stub to backend.core. - Deleted Compat.ReticulumTransport.registeredDestinationHashes() (grep-confirmed zero refs; sibling registeredLinkCallbackHashes() stays — still used). This is the C3(b) seam the NE full-delivery path (C3c, A5-gated) consumes. Columba-Swift green.

A tcpReconnectScheduled guard prevents a storm of .waiting/.failed callbacks stacking overlapping reconnects; a stale-connection guard (=== tcpConnection) stops a late callback from a replaced socket tearing down the live one. Both .failed and .waiting now drive the backoff (previously .waiting only logged). tcpReceiveBuffer is reset on every teardown path so a half-frame from a dead socket can't corrupt the next connection's HDLC framing. - Add NWPathMonitor (started in startTunnel on configQueue, cancelled in stopTunnel): on a satisfied path whose primary interface type actually changed (wifi<->cellular) with an active relay, proactively tear down + re-apply instead of waiting for the dead socket to time out. Guarded against redundant re-applies (baseline sample + real-change only). - NO-PII: all logs via ExtensionDiagLog, coarse interface labels only (wifi/cellular/...), no SSID/address/iface-name, no host:port, no payload. NWPath qualified as Network.NWPath (NetworkExtension also exports a legacy NWPath -> ambiguous). Validated via the ColumbaNetworkExtension scheme.

APP_CONDITIONS = [COLUMBA_BACKEND_SWIFT, ENABLE_NETWORK_EXTENSION]. Re-running added ENABLE_NETWORK_EXTENSION to the existing Debug-Swift/Release-Swift app configs. - This compiles the ~9 parked #if ENABLE_NETWORK_EXTENSION blocks (TunnelManager, ExtensionFrameReader, AppServices tunnel-mode wiring, 2 Settings views). The flip surfaced exactly one parked-code gap: applyTunnelModeToInterfaces calls beginTunnelMode/endTunnelMode on the Compat AutoInterface, which (unlike Compat TCPInterface) lacked them. Added the same no-op stubs to Compat.AutoInterface (the Compat facade has no underlying ReticulumSwift interface; the real tunnel-mode hook is Swift-backend-side, wired NE-side in A5/C3). Validated: Columba-Swift (gated app code compiles) AND ColumbaNetworkExtension schemes green; pbxproj Xcodeproj round-trip preserved all manual A1/C7 entries (AGBF/EDLF/EDL1B/EDL2B), diff is 7+/7- (conditions only, no reformat). C2(c) on-demand-connect + C2(e) NE lib-linking remain.

A5a rooted the NE's lxmf-swift.db under the App-Group container, but the app's grdbDatabaseFilePath still pointed at process-local Application Support (unreachable by the NE) -> they never converged. Fix the mismatch at its root with a single source of truth: - Sources/Shared/AppGroupPaths.swift (NEW, Foundation-only, both targets): canonical /Columba/python-/lxmf-swift.db (+ ratchets), nil when the container is unavailable (no process-local fallback inside the helper — that's the drift it prevents). - AppServices.grdbDatabaseFilePath -> AppGroupPaths (legacy process-local kept only as the container-unavailable fallback). migrateLXMFDatabaseToAppGroupIfNeeded(): one-time, SharedDefaults flag lxmf_db_migrated_to_appgroup, copies lxmf-swift.db + -wal + -shm (correct snapshot of an unopened WAL DB) before any MessageRepository attaches; called at all 3 repo-open sites; leaves old files as fallback; retries if the container isn't ready yet. Both backends use MessageRepository post-A0, so both relocate. No `import LXMFSwift` added. - NEReticulumNode now delegates its path accessors to AppGroupPaths -> app == NE provably. pbxproj: AppGroupPaths.swift in BOTH SRCBP (app) + ESRCBP (NE). Both schemes build green. Known nuance (single-identity assumption, matches the file): the migration flag is global, so only the first identity's store migrates if multiple ever coexist.

OutboxEntry mirrors ProxyRequest.lxmfSend (destHashHex/content/method/fieldsData) + optional messageHashHex + createdAt. - ProxyRnsBackend.sendLxmfMessage: when the NE does NOT accept the send (IPC nil/garbled -> ipcFailed, or .error/.unsupported -> node not running), enqueue an OutboxEntry + return .queued (optimistic UI row). .ok unchanged. messageHashHex is nil by design: the canonical LXMF hash is assigned at pack time NE-side, so the RNSAPI-only proxy can't compute it; reconciliation rides the existing NE-delivery -> shared GRDB -> newMessage Darwin refresh. - NEReticulumNode.start(): after the node is fully up, drainOutbox() replays each entry through sendLxmfForIPC. Log+skip on failure (no re-append -> no unbounded requeue loop; a pack/sign failure would just recur). Receiver-side LXMF dedup makes replay safe. - Inert when off: ProxyRnsBackend is constructed only under modelB (false); drain runs only in start() (gated by modelBNodeEnabled=false). With Model B off the outbox file is never touched. pbxproj: OutboxQueue.swift in both Sources phases. Both schemes build green. The A5 keystone is now code-complete (node + store + IPC proxy + outbox); C3 flips it live.

App (proxy selection) + NE (node activation) share ONE switch. - Live TCP relay interface (the A5a TODO(C3)): NEReticulumNode.start() reads the App-Group TCP interface config (Foundation-only parse -> plain (host,port), no Network type across the collision boundary) and registers a ReticulumSwift TCPInterface on the node transport alongside the AppGroupBridge — mirrors SwiftRNSBackend.buildAndAdd's .tcpClient case. Auto/multicast + path-change rebind left as TODO(C3-followup) (TCPInterface self-reconnects via its own backoff). - startTunnel branch: Model-B true -> start the node, skip applyConfigs/startPathMonitor/the configChanged observer (PoC-only, avoids a double-bound relay); false -> the PoC path unchanged. Fixed a latent double-bind: wake() now guards `reticulumNode == nil` so it can't spin up a duplicate PoC NWConnection under Model B. stopTunnel tears down whichever is active. - proxySend injected at the BackendFactory.make() call site (AppServices startPythonBackend, under ENABLE_NETWORK_EXTENSION) via the established lazy MainActor tunnelManager read — so the proxy has the live IPC send whenever Model B is exercised; inert otherwise. - C3(d): the throwaway PoC memory-measurement code (measureRNSFootprint/poc*/startNEMemoryPoC/ nepoc-mem/NE-PoC.xcscheme) was already absent from the source tree — nothing to delete. Default stays FALSE (both sides): the committed runtime default is the PoC dumb-pipe; Model B is opt-in for on-device verification. Both schemes build green.

The chat UI renders via LxmfFieldCodec.unpack(record.packedLxmf), which returns nil on wire bytes -> Swift/NE-backend-delivered attachments + icons silently didn't render. MessageRepository now normalizes both forms (recoverFields + normalizedFieldMap): - Strict WIRE-FIRST discriminator: try LXMFSwift.LXMessage.unpackFromBytes(bytes, sourceIdentity: nil); non-empty .fields -> wire row (extract fields, no sig re-validation — the router already validated at receive time + nil identity still populates .fields); else -> field-map (or empty). Wire-first is load-bearing: the reverse (field-codec first) is unsafe because unpackMsgPack reads byte 0 and IGNORES trailing bytes, so a wire row whose leading hash byte is a fixmap marker (~1/16) would decode a bogus map and drop attachments. unpackFromBytes's size guard (>96) + strict typed-array shape make a field-map-misread-as-wire near-zero. - mapRecord re-packs wire rows to a field map so the UI's LxmfFieldCodec.unpack works uniformly; mapToLXMessage uses recoverFields for .fields + normalizedFieldMap for .packed. Field-map rows pass through verbatim (only the wire branch does extra work). All read paths flow through these. Tests (MessageRepositoryAdapterTests, exercise the real production adapter): a genuine field-map row AND a genuine signed-wire row (real Identity + msg.pack()) both recover image/file/icon through mapRecord + mapToLXMessage. TEST SUCCEEDED (13 tests, 0 failures; existing A0 adapter tests intact).

Info.plist already declares the bluetooth-central/peripheral background modes. CAVEAT (documented inline): the BLE DELIVERY path is Python-coupled — the Swift backend has NO native BLE delivery, so a background BLE wake only completes delivery+notify under the Python backend. Native Swift BLE delivery is a follow-on. Scoped to BLE-direct; RNode wake left as best-effort (SwiftRNodeBridge intentionally not given a restore id). App scheme builds green.

The pre-existing quick toggle was upgraded to install()+start() + full NEVPNStatus status text. Added gated `import NetworkExtension` to SettingsView. pbxproj: BackgroundTransportView.swift in the app Sources phase only (not the extension). App scheme builds green. Visual polish is device/screenshot-verified.

The plan assumed this wiring "already present"; it wasn't. support/embed-ne.rb (idempotent Xcodeproj script): adds the app->NE target dependency, an "Embed App Extensions" copy-files phase (dstSubfolderSpec=13 PlugIns, CodeSignOnCopy), and ensures the NE target carries DEVELOPMENT_TEAM + Automatic signing. Verified on a signed device build (generic/platform=iOS, -allowProvisioningUpdates): the NE now builds, embeds into PlugIns/, and code-signs with the correct auto-managed profile — entitlements confirmed: packet-tunnel-provider + App Group group.network.columba.Columba + keychain group .network.columba.Columba.shared (A3). Installed to a physical iPhone 14 via devicectl. Default runtime path remains the PoC dumb-pipe (modelBBackgroundNE=false).

Root cause: applyTunnelModeToInterfaces was only invoked from TunnelManager.onStatusChange (VPN status transitions), never from applyInterfaceChanges (hot add/remove). So any interface added while the tunnel was already up never entered tunnel mode (never bridged through the extension). Fix: track tunnelModeActive (set in applyTunnelModeToInterfaces); applyInterfaceChanges now calls reapplyTunnelModeIfActive() after the hot-add loop, so an interface added while the tunnel is up is brought into tunnel mode immediately.

The prior hot-reload fix (9fafd97) didn't cover the launch path (interfaces come up via Step 7 -> connectTCPInterface, not applyInterfaceChanges). Fix: connectTCPInterface and startAutoInterface now call reapplyTunnelModeIfActive() after the interface is registered. tunnelModeActive is set true even when onStatusChange fires with zero interfaces, so the re-assert engages the moment the interface exists — regardless of launch/connect ordering. Combined with onStatusChange (status changes) and applyInterfaceChanges (hot-reload), all three interface-establishment paths now bridge through the extension. Device build green.

Three fixes: - Fixed the keychain bundle-seed-id probe (AppServices.keychainAccessGroupPrefix): it read the access group from SecItemAdd's RESULT (which omits kSecAttrAccessGroup) and added a value-less item — so it always returned nil. A3's shared keychain group was therefore NEVER resolved; the identity silently lived in the app's default group, unreachable by the NE. Now: add a value + read the group back via CopyMatching. - shareIdentityForModelB(): on the active multi-identity init path (initialize(identity:), which never calls loadOrCreateIdentity), resolve the shared group, write it to the App Group (resolvedSharedKeychainGroup) so the NE doesn't have to probe (its probe fails while locked), and persist the identity into the shared keychain group so the NE can load it. - NEReticulumNode.sharedKeychainAccessGroup() reads the app-shared group from the App Group first (probe-free, locked-safe), falling back to the local probe. - TEMP (bring-up): BackendPreference.modelB + NEReticulumNode.modelBNodeEnabled default to true so every launch runs Model B. REVERT to false + add a UI toggle before ship (task #13). Verified on device: NEReticulumNode loads identity=6c7adfca, registers the TCP relay interface, starts with delivery dest=a3979878. Remaining: ProxyRnsBackend IPC start returns ipcFailed; verify NE TCP connects to the relay + inbound/outbound traffic flows (next bring-up iterations).

The sender receives a **delivery proof** (RNS link delivery). +6. On next open, the app reads the message from the shared GRDB — no re-fetch. + +This whole path runs in the NE while the app is suspended/locked. + +## Outbound / send flow + +1. The app composes a message and calls `ProxyRnsBackend.sendLxmfMessage(...)`. +2. That marshals a `composeOutbound` envelope (dest, content, `LxmfFieldCodec`- + packed fields, method) over the IPC seam to the NE. +3. The NE's `sendLxmfForIPC(...)` builds the `LXMessage` with the **shared** + identity, persists it, and `transport.send` selects the path automatically + (path-table lookup → TCP direct, or via the AppGroupBridge → app → radio). +4. Outbound state flows back via the GRDB `messages.state` column + `dbChanged`. +5. **Durable outbox:** if the NE isn't up when the app sends, the request is + persisted to an App-Group outbox and drained on the next NE start + (`NEReticulumNode.drainOutbox`). + +## Announce flow + +The NE announces its own `lxmf.delivery` destination — the app can't drive +announces while suspended: + +- **on node start**, once the relay reports connected (`startAnnounceScheduler` + → `waitForRelayConnected` → `selfAnnounce`); +- **on relay (re)connect** (`onRelayReconnected`, wired via + `transport.setOnInterfaceConnected`) — so a relay that restarted (and lost its + path table) promptly relearns us, instead of waiting for the interval; +- **periodically**, on the user's configured interval (mirrors the app's + `AutoAnnounceManager`). + +The app's "announce now" button routes through `ProxyRnsBackend.announce` → IPC +→ `NEReticulumNode.announceForIPC`. + +--- + +## IPC + bridge mechanics + +- **Control IPC** (`Sources/Shared/ProxyIPC.swift`): a Foundation-only + `ProxyRequest`/`ProxyResponse` envelope (magic + version framed). The app's + `ProxyRnsBackend` (`Sources/RNSBackendProxy/`) sends it over + `NETunnelProviderSession.sendProviderMessage`; the NE decodes it in + `PacketTunnelProvider.handleAppMessage` and dispatches to `NEReticulumNode`'s + `…ForIPC` methods. The seam is Foundation-only so the NE never imports RNSAPI + (see the collision rule). +- **Frame bridge** (`Sources/Shared/AppGroupBridgeInterface.swift`): a real + `ReticulumSwift.NetworkInterface` (`mode = .full`, so announces propagate both + ways) registered on the NE's transport. It carries radio frames app↔NE over an + App-Group `SharedFrameQueue` (POSIX-flock'd file, restart-idempotent — survives + NE jetsam) split into two named unidirectional queues (`a2e` / `e2a`), with a + `radioFrameReady` Darwin notification app→NE and `packetReady` NE→app. + +## Shared state + +- **Identity:** shared keychain access group + (`$(AppIdentifierPrefix)network.columba.Columba.shared`). The app creates the + identity and writes it to the shared group; the NE reads it + (`NEReticulumNode.loadSharedIdentity`). Accessibility + `…AfterFirstUnlockThisDeviceOnly` (NE-readable while locked, post-first-unlock). + The app also publishes the *resolved* group name to App-Group UserDefaults so + the NE can resolve it even when the bundle-seed probe can't run (locked). +- **Message store:** `LXMFSwift.LXMFDatabase` (GRDB, WAL) in the App-Group + container. **Single writer = the NE**; the app opens it **read-only**. Cross- + process refresh is the `dbChanged` Darwin notification (GRDB observation does + not cross processes). File protection + `completeUntilFirstUserAuthentication` so it's writable while locked. + +--- + +## Load-bearing invariants + +1. **Single node = the NE.** The app owns no `lxmf.delivery` destination and no + `LXMRouter`. On launch the app must NOT start a competing destination-owning + backend (gated for Model B in `AppServices` / the startup interface loop — + e.g. it skips the app-side TCP interface). +2. **Single writer = the NE.** The app is read-only on the GRDB store; outbound + composed in-app is *handed to the NE to send + persist*. +3. **Durable dedup.** Dedup keys on the path-independent + `LXMessage.hash`; it lives in the GRDB store (`messageExists`) so it survives + an NE restart and spans transport paths (TCP copy == BLE copy). +4. **Always-the-node.** The node identity is a pure function of (shared identity + + shared store), so NE jetsam/restart is transparent — it comes back as the + same node. On-demand connect (`NEOnDemandRuleConnect`) relaunches it. +5. **The RNSAPI / ReticulumSwift collision rule.** RNSAPI's `Compat` layer + re-declares the same type names as `ReticulumSwift`. Files that conform to + `ReticulumSwift` protocols or use its types import **ReticulumSwift (+ + Foundation) ONLY, never RNSAPI**. The NE target is entirely RNSAPI-free; the + proxy seam (`ProxyIPC`) is Foundation-only so no RNSAPI/ReticulumSwift type + ever crosses it. `AppServices` stays RNSAPI-typed; LXMFSwift is confined to + `MessageRepository`. + +--- + +## Build / packaging gotchas + +- **Build the NE via the `ColumbaNetworkExtension` scheme**, not the + `Columba-Swift` app scheme — the app scheme does NOT compile the NE (a false- + green trap). See `reference_ne_build_scheme.md`. +- Model B code is on the **`Debug-Swift` / `Release-Swift`** configs + (`COLUMBA_BACKEND_SWIFT` + `ENABLE_NETWORK_EXTENSION`). +- The NE is embedded + signed via `support/embed-ne.rb`; its deps + (ReticulumSwift + LXMFSwift) via `support/add-ne-backend-deps.rb`. +- **Runtime gate:** `BackendPreference.modelB` (app) and + `NEReticulumNode.modelBNodeEnabled` (NE) read the shared App-Group flag + `modelBBackgroundNE`. Model B only works on the Swift backend. + +### TCP egress from inside the tunnel +`reticulum-swift`'s `TCPTransport` sets `bypassTunnelEgress` +(`prohibitedInterfaceTypes = [.other]`) when the NE host enables it, so the +relay socket uses a physical interface rather than the provider's own utun. +(Note: as of the 2026-06-02 bring-up this turned out *not* to be the actual +egress fix — the NE socket was already egressing fine; it's retained as a +defensive measure.

NEReticulumNode.modelBNodeEnabled hardcoded true (the NE only exists on this build). Removes the cross-process flag race that left the NE in sniff mode while the app came up as the proxy (ipcFailed). - ProxyRnsBackend.start: retry the handshake until the NE node is ready (~12s), so a cold start / jetsam relaunch no longer fails ipcFailed/backendNotReady. Verified on-device: clean Model B bring-up every launch, end-to-end DIRECT delivery proven (DELIVERED proof). - Removed the "Background delivery (Model B)" Settings toggle + modelBEnabled / applyModelBSelection. - Display-name fix: when an announce carrying a name is heard, stamp it onto an existing nil-name conversation (the announce arrives after the NE creates the row on inbound, so the title was stuck on the "Peer " fallback). Verified on-device. - reticulum-swift pin -> 9fa6645 (bypassTunnelEgress merged via PR #18). - docs/MODEL_B_TESTING_TODO.md (radio / lock-screen / under-pressure GATE) + flows/bug1-network-tab-repro.yml. TEMP (remove when the render investigation closes): the [MSG] loadMessages and [DIAG-STORE] announce-read diag logs. The empty-thread-via-Network-tab bug is narrowed to a view/nav issue — cross-process reads are proven fresh (msgs=1), not a read-path problem — so the A5 readonly:true refactor is not needed.

Sample the whole transfer. +- [ ] Run each scenario **5×** to catch variance. + +### 3c. Verdict (iPhone 14) +- [ ] **PASS:** peak resident stays **≥ 8 MB below** the `os_proc_available_memory()=0` + point across all 5 runs, **zero** memory-reason stops → Model B holds for that + payload class. +- [ ] **CONDITIONAL:** small fits but the large attachment breaches → ship small- + payload delivery now; large-payload delivery gated on finishing Track L + streaming (L2/L3 landed; verify the peak is window-bounded, not payload-bounded). +- [ ] **FAIL:** even a small Resource gets jetsam-killed → escalate; fall back to + sniff-only + complete-on-open and re-scope. + +> Shortcut now that delivery actually works: you can get a first read **without** +> the harness — drive real traffic from the Android peer, then pull `ext-diag.log` +> and read the sampler line just before/after the transfer.

UI: the BLE connections page, the interface status badge, the Network Status list and the Settings network card all now read the NE's native interfaces -- over a new .bleConnections proxy IPC and a statusSnapshot enriched with type/peer/state -- instead of the app's Compat transport stub, which never holds the NE's real interfaces under Model B.

Two gaps left incoming messages AND delivery proofs reaching the NE but never surfacing in an open conversation: - The NE posted the Darwin refresh notification only on inbound delivery (didReceiveMessage), not on delivery-proof / outbound state changes -- so sent-message checkmarks never advanced past the single tick. Post it from didConfirmDelivery / didUpdateMessage / didFailMessage too. - The open thread (MessagingViewModel) only observes the in-process messageReceivedNotification, which is dead under Model B.

NEReticulumNode.stop() tore down the RNS stack but never stopped `bleSeamTransport`, so on a VPN reconnect (iOS reuses the NE process) the orphaned seam transport's Darwin observer kept draining the app->NE queue (readAllAndClear), STEALING the discovery/incoming-connection/fragment events from the freshly-started node, which then spawned its BLE interface but never registered a peer (peers=0, no announces in or out). stop() now stops the seam transport and drops the interface (without `.disconnect()`, which would `.shutdown` the app's shared CoreBluetooth radio over the seam), and AppGroupBLEDriver finishes its three streams when the seam inbound ends so the old interface's consumer tasks exit cleanly instead of blocking. Verified on-device: bidirectional announces + messages over BLE. Also: NE-built local notifications now resolve the sender's display name from the shared conversation store (matching the app's NotificationService) instead of a bare `[hash]`. (Path-table persistence is temporarily in-memory pending a suspend-safe redo; `appGroupPathTableDatabasePath` is staged for it.)

Replace with event-driven refresh: - NotificationObserver gains a second channel: it observes the NE's `network.columba.networkStateChanged` Darwin notification and re-posts it in-process as `networkStateChangedInApp`. - NetworkStatusViewModel: drop the 1s poll loop; refresh once on the push (plus one initial load). - InterfaceManagementViewModel: the BLE badge fetches the NE once on the push and caches it; the 1s loop keeps only app-local reads (MPC/Auto/RNode). The Model B TCP-relay status is still polled (follow-up: needs an NE interface-state push). - BLEConnectionsView: connection list updates on the push; the live byte/RSSI counters keep a slowed 4s while-visible poll (continuous, no discrete event).

The legacy Model A path — where the Python IOSRNodeInterface drove a Swift CoreBluetooth NUS client (SwiftRNodeBridge) over a ctypes columba_rnode_* C-ABI — is now dead. Remove it: - delete SwiftRNodeBridge.swift, RNodeNativeBindings.swift (the C-ABI shims), PythonRNodeCallbackBridge.swift, and app/rnode/IOSRNodeInterface.py - AppServices: drop the RNode callback-bridge install + the .py deploy step - PythonConfigWriter: .rnode now emits a disabled placeholder (the Python backend has no RNode implementation; RNode is Model B / Swift-only) - PythonBridge: remove invokeRNodeCallback - rns_bridge.py: remove the RNode callback registry + its clear() calls - update stale comments that referenced the removed types Columba-Swift (Model B) builds clean. The Python backend keeps full mesh BLE; it just no longer offers an RNode interface.

Any Lucide icon is now available app-wide via the font. Use it for the RNode interface icon on the Network announce cards + the RNode filter chip (Lucide "antenna", matching Android), via a "lucide:" convention in ContactCard.interfaceIconView. Tinted to match the existing badge (subdued gray — same as Android's onSurfaceVariant; LoRa-orange is map-markers-only there). Generated from lucide-static 0.544.0; Lucide is ISC-licensed (see lucide-font-LICENSE.txt).

The swift LXMF stack already implements propagation end-to-end — this wires the app's selected propagation node + a sync schedule across the App-Group seam into the NE's router, and mirrors live sync state back for the UI. Seam (Foundation-only, both targets): - PropagationSeam.swift: PropagationSeamConfig (PN hash, stamp cost, interval, periodic flag) app→NE + sync-now trigger; PropagationSyncStateSnapshot NE→app. - 5 SharedDefaultsConstants keys (config / sync-now / sync-state + Darwin names). NE (NEReticulumNode): - applyPropagationConfig wires the PN onto the router (setOutboundPropagationNode + setPropagationStampCost); config + sync-now Darwin observers; a periodic sync scheduler mirroring the announce scheduler; runOneSyncFireAndForget runs syncFromPropagationNode in a detached child with a 150s watchdog + in-flight guard so the 120s SYNC_TIMEOUT never blocks the loop/IPC. One-shot sync on relay reconnect. didUpdateSyncState/didCompleteSyncWithNewMessages write the state snapshot (message-arrival push stays on the existing inbound path only). App: - PropagationNodeManager publishes the seam from save/loadPreferences (modelB- gated); syncNow + startPeriodicSync gain modelB branches (post sync-now / publish, NE owns cadence); tracks + persists stamp cost (SettingsRepository) for a correct cold start. NotificationObserver bridges the NE sync-state channel; the manager mirrors snapshots into syncState. - SettingsViewModel.saveDeliverySettings persists so interval/periodic edits (incl. disable) reach the NE. - SyncStatusBottomSheet (mirrors Columba-Android), auto-shown from Chats while a sync is active. - test-prop-sync (ColumbaTestPropSync) routes through the manager under Model B (backend.propagationSync is a no-op proxy there). Verified on device (iPhone 14, Debug-Swift): propagated_echo smoke PASS — device→PN→echo-bot→PN→device, echo delivered, sync_attempts=1. Both schemes build (Columba python + ColumbaNetworkExtension swift).

These three are architecture-independent correctness bugs Model B lacked; the rest of #57 is MOOT (tunnel/interface-bridge plumbing the in-NE node replaces) or already COVERED (the in-NE node's decode + ExtensionDiagLog). The deferred multi-relay capability is tracked separately (issue #91). 1. App cold-start no longer blocks on the notification auth sheet (#57 fc9b0b8). ColumbaApp Step 8 awaited requestPermission() before setting isInitialized, so the OS prompt held RootView setup hostage — and on a fresh-install device the smoke harness (no UI driver) could never tap Allow, so init hung. Now fire-and-forget; the foreground UN delegate is already installed in init(). 2. Register app-side notification/announce defaults at launch (#57 dc1024b). notifications_enabled:true was registered only inside SettingsViewModel .loadLocalSettings() (lazy, on first Settings open), so a fresh install that never opened Settings left it unregistered and NotificationService's `guard bool(forKey:)` suppressed the foreground notification path. Moved to a static registerLocalDefaults() called from App.init(). (Model-B background notifications come from the NE, which gates only on system auth — unaffected.) 3. "Disable Background Transport" now actually disables (#57 38f8d2e). install() arms isOnDemandEnabled + NEOnDemandRuleConnect(); stop() was a bare stopVPNTunnel(), so iOS auto-reconnected the NE via the armed rule — the toggle was a no-op. New TunnelManager.disable() clears on-demand + isEnabled and persists before stopping; both affordances (BackgroundTransportView, SettingsView) call it. Also: applyTunnelModeToInterfaces is now TCP-only — it no longer tunnels the AutoInterface (#57 d3719c2 #3). Forwarding Auto frames to tunnel.sendFrame black-holes them (PacketTunnelProvider drops non-ProxyRequest frames; the NE has no UDP/Auto path), so tunneling Auto could only break background Auto outbound. Builds clean (ColumbaNetworkExtension scheme, Debug-Swift, device).

Two P1s were the same bug class — NEReticulumNode.stop() leaking raw passUnretained Darwin observers / seam transports across a same-process NE restart (PacketTunnelProvider builds a fresh node per startTunnel; iOS reuses the process) → frame-stealing + use-after-free. P1 — Darwin observers leaked on stop (use-after-free): stop() never removed the 3 observers self-registered with Unmanaged.passUnretained(self): the RNode-config observer and BOTH propagation observers (config-changed + sync-now). Swept ALL of them (not just the flagged ones) via CFNotificationCenterRemoveEveryObserver(self) and reset both *ObserverRegistered guards so the next start() re-registers cleanly. P1 — RNode seam transport not torn down on stop (frame stealing + dangling): stop() tore down the BLE seam but left rnodeInterface live; its AppGroupRNodeSeamWire keeps a rnodeSeamA2N Darwin observer that, on restart, steals KISS frames from the fresh node and dangles after deinit. Now disconnect()+removeInterface()+nil it while transport is still alive. P2 — TCP relay port silently wrapped: loadTCPRelayConfig used UInt16(truncatingIfNeeded: port) on an unconstrained JSON Int, so 65536→0 / 131071→65535 dialed a wrong/zero port instead of skipping. Now `guard port > 0, port <= 65535` and a checked UInt16(port). (Swept for sibling truncations: the other truncatingIfNeeded uses are intentional MsgPack/LXMF wire decodes; BLE MTU already uses UInt16(clamping:).) P2 — bundleSeedProbe keychain item accumulated: the team-id-prefix probe added a generic-password item and never removed it. Fixed BOTH mirror sites Greptile noted (NEReticulumNode + AppServices) with a SecItemDelete after the read; the probe re-adds cheaply on next resolution.

Fixed with an `isStarting` latch claimed SYNCHRONOUSLY before the first await (defer-released so a failed start, e.g. identity not yet created, still retries). Proactive sweep of the same bug class (check-then-act across await on actor state) found the identical defect, NOT flagged by greptile, in runOneSyncFireAndForget: it set `syncInFlight = true` only AFTER `await waitForRelayConnected(2s)`, so the periodic scheduler racing a manual "Sync Now" Darwin trigger could start an OVERLAPPING sync.

Added a `startGeneration` token: start() snapshots it up front and, under stateLock, refuses to commit if stop() bumped it meanwhile. 2. announce-poller swallowed its own cancellation. `try? await Task.sleep` ate the CancellationError stop() raises, firing one extra `.heardAnnounces` IPC round- trip before the while-guard re-checked.

Two-pronged: - Root cause: `stopRequested` flag set by stop() unconditionally (before the isRunning guard) and reset at the top of each start(); start() checks it after full init and runs a complete teardown (observers + seam transports) instead of returning a started-but-meant-to-stop node. - Safety net: a `deinit` that unconditionally CFNotificationCenterRemoveEveryObserver for self (same idiom as NotificationObserver.deinit), so the observers can never outlive the actor regardless of orphaning path.

That task was unmanaged, so: - if stop() runs before it executes, stop()'s `ri.disconnect()` is a no-op (connect() hasn't run), then the detached task later connect()s and registers the rnodeSeamA2N Darwin observer on an orphaned transport; and - a rapid rnodeConfigChanged re-invocation tears down iface_v1 and builds iface_v2, but iface_v1's detached task still connect()s and re-registers its observer. Either way two live wires observe rnodeSeamA2N and steal each other's KISS frames on the next NE restart — the same hazard the BLE-seam teardown already guards. Fix: store the task in `rnodeAddInterfaceTask` and cancel it at the top of setupRNodeInterface (reconfig) and in stop() — mirroring announceTask/ propagationSyncTask. The detached body now checks cancellation before AND after addInterface and, if superseded mid-connect, rolls back (disconnect → removeInterface on the captured tp/iface) so no orphaned seam observer survives.

Added PropagationSeamConfig.minSyncInterval (30s) + an `effectiveSyncInterval` accessor (max(floor, syncInterval)) and used it in the scheduler sleep + the PN-set log. The floor lives at the point of use, NOT init: `loadFromAppGroup()` decodes via Codable, which bypasses the custom init — an init-time clamp wouldn't catch the corrupted-defaults path.
