From be663f2deab688ea74455cf628f0047a2f1cc489 Mon Sep 17 00:00:00 2001 From: torlando-tech Date: Wed, 29 Apr 2026 11:16:12 -0400 Subject: [PATCH 01/39] feat: enable Network Extension (Phase 2 of background-connectivity plan) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 1.6-1.9 of the staged plan plus the onboarding step: - TunnelManager.disable() now sets isEnabled=false and saveToPreferences() after stopVPNTunnel(); calling stopVPNTunnel() alone leaves the profile partially-active in iOS routing, which was the root cause of the "toggle off but TCP stays broken" report. - AppServices auto-restarts the tunnel from the App Group's tunnel_enabled preference at initialize() time so users don't have to re-toggle on every launch. - SettingsView toggle uses do/catch with DiagLog and an inline error label so install / start failures (entitlement issues, declined VPN-profile prompts) are visible instead of silently bouncing the toggle off. Toggle persists tunnel_enabled on success. - New onboarding step (page 4 of 6) "Stay Connected in the Background" with a pre-checked toggle. completeOnboarding() writes the value to the App Group so AppServices can auto-start on first launch and trigger the VPN-profile prompt at the right moment. - ENABLE_NETWORK_EXTENSION compilation flag is now set on ColumbaApp's Debug + Release configs alongside CODE_SIGN_ENTITLEMENTS pointing at ColumbaApp.entitlements. The app target depends on the extension target and embeds it via a PBXCopyFilesBuildPhase (Foundation Extensions, dstSubfolderSpec=13). Verified with xcodebuild — Debug iphonesimulator build succeeds and copies ColumbaNetworkExtension.appex into ColumbaApp.app/PlugIns.

Adds a checkCancellation() in TunnelManager.start() right before startVPNTunnel() so a cancelled caller can't fire iOS's VPN bring-up after the await.

Root cause: the extension's `NWConnectionGroup` is hard-coded to `ff02::1` on a single port, but reticulum-swift's AutoInterface derives its multicast group per groupId (`ff12:0:...` from `multicastAddress(for:)`) and runs per-peer unicast on a separate data port (42671). Putting Auto into tunnel mode tore down the local NWConnectionGroup and replaced it with a non-functional one in the extension — hence no peer discovery and no traffic. Fix: skip Auto in `applyTunnelModeToInterfaces`. AutoInterface is intrinsically local-Wi-Fi only — iOS suspending multicast in the background is an OS-level limit, not something the tunnel can paper over. TCP keeps delivering messages while backgrounded, which is the whole point of Phase 1. A future change can reimplement the Auto protocol (groupId-derived multicast + per-peer unicast) inside the extension if we want background Auto too.

Tunneling Auto through that broken listener killed peer discovery and silently dropped data. This change links `ReticulumSwift` into the extension target and runs an actual `AutoInterface` instance inside the Network Extension via a new `ExtensionAutoBridge`: - `ExtensionAutoBridge` instantiates `AutoInterface` with the configured group id, sets a delegate that funnels every received packet (parent AutoInterface + every spawned `AutoInterfacePeer` sub-interface) into `SharedFrameQueue` with the Auto tag, and exposes a `send(_:)` that hands outbound bytes off to `AutoInterface.send(_:)` for the regular per-peer fan-out. - `PacketTunnelProvider` now drives the bridge from `applyConfigsLocked` (start / stop on group-id diff) and routes app outbound (the `auto` tag in `handleAppMessage`) through `autoBridge.send(_:)`. - `applyTunnelModeToInterfaces` puts the app's AutoInterface back into tunnel mode when the VPN is up — this reverts the temporary "Auto stays local" stop-gap. Net effect: once the tunnel is connected, Auto peer discovery and data delivery happen entirely inside the extension, so they keep working when the app is backgrounded.

Multicast loopback works, real LAN packets never arrive. 2. From-scratch implementation on Apple's Network framework (`NWMulticastGroup` for HELLO discovery + `NWListener` for inbound unicast data + per-peer `NWConnection` for outbound) — same outcome. `NWListener.newConnectionHandler` never fires even with no `requiredInterfaceType`. Confirms the limitation isn't the API choice; it's the extension sandbox. Reverts both bridge implementations and the `onWillStart` / "release UDP sockets before extension launch" plumbing. Phase 1 ships TCP-only background, which is the win that actually solves issue #54 (messages-while-locked over TCP). AutoInterface keeps working locally for foreground use — same behaviour the user had before this PR. Background AutoInterface needs a different architecture (e.g. configuring the tunnel's `includedRoutes` to capture the multicast group + dataPort and reading them via `packetFlow`) and is left for a future PR. Keeps the `ExtensionDiagLog` plumbing in place for future debugging and the diff logic in `applyConfigsLocked` so the re-enable path is short.

Exit code 0 when the expected entries are present. The current revision asserts the basic "tunnel reached enabled state" path because auto-in-extension is reverted in this PR. Verifier comments mark where to re-enable the `NWListener accepted inbound` assertion when we revisit background AutoInterface with a different architecture. Known gap: iOS keeps the running extension instance across app re-deploys, so the harness still needs the user to delete and re-add the VPN profile in iOS Settings once per build to load the new extension binary. Plan is to bake a `/debug/reload- extension` `handleAppMessage` command into the extension that calls `cancelTunnelWithError` so the harness can force-reload without any UI taps — see TODO in `run_test.sh`.

Re-run Onboarding orphaned existing chats. CompletePage's onAppear raced the outer view's isRestart propagation, so prepareIdentity created a fresh identity and switched to it before isRestart reached the view model. Move isRestart into the view model's init so prepareIdentity / completeOnboarding both see the correct flag from the first call. 2. switchIdentity created a duplicate "tcp-server" TCPInterface. The legacy initialize(identity:identityHash:tcpServerAddress:) path parsed the supplied address and created a TCPInterface with id "tcp-server" alongside the InterfaceRepository-owned UUID entity that Step 7 connects on identity-switch. Both ended up in tunnel mode, splitting outbound. Drop the parameter and the synthesized interface — Step 7's repository iteration is now the only source of TCP interfaces. 3. AutoInterface in the extension is non-functional. Empirical testing on device confirmed iOS sandboxes UDP outbound from NEPacketTunnelProvider for both Network framework primitives (NWConnection / NWConnectionGroup silently drops) and POSIX sendto (ENETUNREACH). Inbound works (NWListener accepts unicast, POSIX IPV6_JOIN_GROUP receives multicast) but the sandbox blocks the reply path, so Auto cannot peer from the extension at all. Revert applyTunnelModeToInterfaces to TCP-only and update onboarding + Settings copy to make Auto's foreground-only behaviour explicit. BLE / RNode keep their own background-mode plumbing (Phase 2) and aren't covered by the same caveat. Plus race fix in connectTCPInterface: when the tunnel auto-starts during cold launch and reaches .connected before Step 7 has populated tcpInterfaces, the late-added interface stays on its local NWConnection. Apply tunnel mode at the late-add site too. --- Columba.xcodeproj/project.pbxproj | 12 +- Sources/ColumbaApp/App/ColumbaApp.swift | 5 +- Sources/ColumbaApp/Services/AppServices.swift | 145 ++++-- .../ColumbaApp/Services/TunnelManager.swift | 19 + .../ViewModels/OnboardingViewModel.swift | 33 +- .../Onboarding/BackgroundTransportPage.swift | 13 +- .../Views/Onboarding/OnboardingView.swift | 31 +- .../Views/Settings/IdentityManagerView.swift | 16 +- .../Views/Settings/SettingsView.swift | 49 +- .../ExtensionAutoBridge.swift | 474 +++++++++++------- .../PacketTunnelProvider.swift | 145 +++++- 11 files changed, 670 insertions(+), 272 deletions(-) diff --git a/Columba.xcodeproj/project.pbxproj b/Columba.xcodeproj/project.pbxproj index b0cac504..667cc12c 100644 --- a/Columba.xcodeproj/project.pbxproj +++ b/Columba.xcodeproj/project.pbxproj @@ -959,7 +959,7 @@ buildSettings = { CODE_SIGN_ENTITLEMENTS = Sources/ColumbaNetworkExtension/ColumbaNetworkExtension.entitlements; CODE_SIGN_STYLE = Automatic; - CURRENT_PROJECT_VERSION = 12; + CURRENT_PROJECT_VERSION = 29; GENERATE_INFOPLIST_FILE = YES; INFOPLIST_FILE = Sources/ColumbaNetworkExtension/Info.plist; INFOPLIST_KEY_CFBundleDisplayName = "Columba Transport"; @@ -985,7 +985,7 @@ buildSettings = { CODE_SIGN_ENTITLEMENTS = Sources/ColumbaNetworkExtension/ColumbaNetworkExtension.entitlements; CODE_SIGN_STYLE = Automatic; - CURRENT_PROJECT_VERSION = 12; + CURRENT_PROJECT_VERSION = 29; GENERATE_INFOPLIST_FILE = YES; INFOPLIST_FILE = Sources/ColumbaNetworkExtension/Info.plist; INFOPLIST_KEY_CFBundleDisplayName = "Columba Transport"; @@ -1070,7 +1070,7 @@ ASSETCATALOG_COMPILER_GLOBAL_ACCENT_COLOR_NAME = AccentColor; CODE_SIGN_ENTITLEMENTS = Sources/ColumbaApp/Resources/ColumbaApp.entitlements; CODE_SIGN_STYLE = Automatic; - CURRENT_PROJECT_VERSION = 12; + CURRENT_PROJECT_VERSION = 29; ENABLE_PREVIEWS = YES; GENERATE_INFOPLIST_FILE = YES; INFOPLIST_FILE = Sources/ColumbaApp/Resources/Info.plist; @@ -1110,7 +1110,7 @@ ASSETCATALOG_COMPILER_GLOBAL_ACCENT_COLOR_NAME = AccentColor; CODE_SIGN_ENTITLEMENTS = Sources/ColumbaApp/Resources/ColumbaApp.entitlements; CODE_SIGN_STYLE = Automatic; - CURRENT_PROJECT_VERSION = 12; + CURRENT_PROJECT_VERSION = 29; ENABLE_PREVIEWS = YES; GENERATE_INFOPLIST_FILE = YES; INFOPLIST_FILE = Sources/ColumbaApp/Resources/Info.plist; @@ -1147,7 +1147,7 @@ buildSettings = { BUNDLE_LOADER = "$(TEST_HOST)"; CODE_SIGN_STYLE = Automatic; - CURRENT_PROJECT_VERSION = 12; + CURRENT_PROJECT_VERSION = 29; GENERATE_INFOPLIST_FILE = YES; IPHONEOS_DEPLOYMENT_TARGET = 17.0; MACOSX_DEPLOYMENT_TARGET = 14.0; @@ -1167,7 +1167,7 @@ buildSettings = { BUNDLE_LOADER = "$(TEST_HOST)"; CODE_SIGN_STYLE = Automatic; - CURRENT_PROJECT_VERSION = 12; + CURRENT_PROJECT_VERSION = 29; GENERATE_INFOPLIST_FILE = YES; IPHONEOS_DEPLOYMENT_TARGET = 17.0; MACOSX_DEPLOYMENT_TARGET = 14.0; diff --git a/Sources/ColumbaApp/App/ColumbaApp.swift b/Sources/ColumbaApp/App/ColumbaApp.swift index 91f04d67..d5285dab 100644 --- a/Sources/ColumbaApp/App/ColumbaApp.swift +++ b/Sources/ColumbaApp/App/ColumbaApp.swift @@ -415,12 +415,11 @@ struct RootView: View { let enabledInterfaces = interfaceRepo.getEnabledInterfaces() DiagLog.log("[STARTUP] Step 4: \(enabledInterfaces.count) enabled interfaces") - // 5.

Config changes for those types still don't take effect without a manual disable/re-enable — separate issue, smaller blast radius, not addressed here. * feat: multi-TCP tunnel — extension manages a connection per entity Previously the Network Extension kept a single `tcpConnection` and a single `currentTCP` endpoint, so enabling two TCP relays in the app silently dropped one — the extension's config loader overwrote `result.tcp` on every iteration and only the last enabled tcpClient in the JSON array got a socket. The other relay was unreachable through the tunnel and inbound from the wrong relay was routed back to whichever `TCPInterface` happened to be first in the app's dictionary. This commit lifts the entire tunnel TCP layer to per-entity: - `SharedFrameQueue` frame format gains a 1-byte entityId-length field and a length-prefixed UTF-8 entity id between the interface tag and the frame payload. Old format frames in flight at the upgrade are lost on first read; the queue is append-and-clear so the lifetime is short. - `TunnelManager.sendFrame` adds an `entityId` parameter and writes it into the IPC envelope sent via `sendProviderMessage`. `connectTCPInterface` and `applyTunnelModeToInterfaces` now capture the entity id in the per-interface tunnel-mode hook so outbound frames from each `TCPInterface` carry their own id. - `ExtensionFrameReader.onTCPFrameReceived` is now `(entityId, data)` and the AppServices handler routes inbound frames to the matching `TCPInterface` by id, with safe fallbacks for empty/legacy ids. - `PacketTunnelProvider` replaces `tcpConnection` / `tcpReceiveBuffer` / `currentTCP` with per-entity dicts. Each `NWConnection` has its own HDLC receive buffer (sharing one buffer between two streams would corrupt frame boundaries), its own state-update handler that only tears down its own entry, and its own `receiveTCPData` recursion so inbound frames are tagged with the right id when appended to the queue. - `applyConfigsLocked` diffs per-entity: an entry whose endpoint is unchanged keeps its connection, a removed entry tears down only its own socket, an edited entry restarts only that socket. Adding a second relay no longer disturbs the first. - `loadInterfaceConfigs` returns `tcps: [String: (host, port)]` keyed by `InterfaceEntity.id` instead of a single optional. `handleAppMessage` parses the new wire format (entityId-length + entityId in front of frame data) and looks up the connection by id, falling back to the sole connection when the id is empty so a hypothetical legacy single-TCP build still routes correctly. * chore: extension diag logs for TCP config/state changes Lifecycle events only — config (re)apply, config removal, state transitions, failure. Per-frame and per-drain logging is omitted to keep the file small. Per-entity tagging in the messages makes multi-TCP behaviour observable without needing syslog access. Used to diagnose the silent-inbound regression that turned out to be the SharedFrameQueue wire-format roll-out interacting with a not-yet-relaunched extension; left in place for future debugging. * feat(InterfaceManagement): add TCP client community-server wizard Mirrors Android Columba's 2-step TCP client wizard at the post-onboarding add-interface surface: server selection (bootstrap/community/custom) → review & configure. Routes Settings → Network Interfaces → + → TCP Client through the wizard instead of the blank manual entry sheet, and reroutes edit-existing for TCP entries to the same flow with pre-filled values. Scoped to the fields TCPClientConfig already supports (host, port, networkName, passphrase). Bootstrap-only flag and SOCKS proxy are deferred. Closes #51 Co-Authored-By: Claude claude-opus-4-7 * fix(MicronParser): persist formatting state across lines (#63) * fix(MicronParser): persist formatting state across lines The line-by-line parse loop hardcoded `currentStyle: .plain` on every parseInline call, so a `Fxxx`Bxxx preamble line consumed its colors into an empty span and the following ASCII art rendered with no fg/bg. Match python NomadNet's MicronParser by promoting currentStyle to a parser-loop local that threads through every parseInline call, with parseInline returning the terminal style so the caller can carry it forward. `< at line-start additionally resets currentStyle to .plain, matching python's `<` semantics. Repro: the index.mu at github.com/fr33n0w/thechatroom uses the preamble shape `F0ff`B52f then ASCII art then `f`b — before this fix the colors were silently dropped. Closes #31 Co-Authored-By: Claude claude-opus-4-7 * fix(NodeDetailsView): allow tapping action buttons on stale-path contacts Browse Site / Start Chat / Set as My Relay were `.disabled(!isOnline)` on a contact's NodeDetailsView, where `isOnline` is just `Date() < entry.expires` from the path table. After cleanupLinks runs `expirePath` on a failed-link destination, the contact's path becomes "expired" until a new announce arrives — but Reticulum's path discovery is exactly designed for that case (issue a path-request, any peer with a recent announce will respond). Greying the button blocks the user from the very operation that would heal the path. Drops the `.disabled` and `.opacity` modifiers from `actionButton(...)` and the relay-toggle button. The underlying flow (`NomadNetBrowserService.resolveValidPath`) already does `pathTable.remove` + `transport.requestPath` + 10s poll, so taps now flow through to the working recovery path. Also reword the expired-hint copy from "Ask them to send an announce from their app, or wait for one to arrive automatically" to "Tap an action to issue a path request — any node on the network with a recent announce will respond." — the original copy is wrong about how Reticulum path discovery works and discourages users from doing the right thing. Co-Authored-By: Claude Opus 4.7 (1M context) * fix(MicronDocumentView): render the chat-room ASCII art correctly Three bugs surfaced once the parser carried `Bxxx background colors forward across lines (faf17e4): 1. Centering broke against the document, not the screen. A wide row (e.g. fr33n0w/thechatroom's 550-char trailing-whitespace line) pushed the VStack out to ~4600pt; centered shorter rows landed at the middle of *that* width — way past the viewport. Fixed by capturing the actual screen viewport via GeometryReader in MonospaceScrollContainer (mirrors Android's `Modifier.widthIn(min = viewportLineWidth)` from NomadNetBrowserScreen.kt:474) and wrapping each scroll-mode row in `.frame(minWidth: viewportWidth, alignment: alignment.swiftUI)`. 2. Row-to-row column alignment drifted by half a cell because Core Text's `textAlignment = .center` strips trailing whitespace when computing the centered offset. Lines with a trailing space centered as if one cell narrower than lines without — visible as the letter "T" of "the chat room" wandering in the ASCII art. UILabel now always renders left-aligned (paragraphStyle and textAlignment) and visual centering is the SwiftUI .frame's job. 3. SF Mono renders Block-Elements (▗▄▖▝▀▘▙▟ etc.) at slightly different pixel widths than ASCII spaces, so 85-char rows of mixed content didn't end up the same width. Bundled JetBrains Mono (Apache 2.0/OFL, Regular + Bold, ~270KB each) for the monospace renderer — every glyph in the file has advance=600 confirmed via fontTools, matching what Android already uses (MicronComposables.kt's `JetBrainsMonoFamily`).

Removes decommissioned / non-existent entries (RNS Amsterdam, RNS BetweenTheBorders, RNS Frankfurt, i2p Reticulum, Reticulum Ireland, TheHub, Kosciuszko, Reticulum Ireland v2, RNS Roaming) and adds the servers that are actually present on the network. i2p is dropped entirely because iOS has no i2p transport. Also collapse the "Bootstrap Servers" / "Community Servers" split in TCPClientWizard into a single "Community Servers" section, since Reticulum-Swift does not yet implement bootstrap-interface mode and splitting them would mislead users into expecting bootstrap behavior. The isBootstrap flag on the data model is preserved so the Android table stays mirrorable. Co-Authored-By: Claude claude-opus-4-7 * feat(auto-announce): granular trigger toggles + new wiring Splits the auto-announce path into three independently-toggleable triggers, all gated behind the existing `auto_announce_enabled` master: - `auto_announce_on_interval` — periodic timer (existing) - `auto_announce_on_tcp_reconnect` — fires on TCP / RNode reconnect - `auto_announce_on_peer_spawned` — fires when AutoInterface / BLE / MPC accepts a new peer All three default true to preserve the previous "all triggers active when master is on" behaviour. Wiring: - `AppServices.configureTransportCallbacks` now uses reticulum-swift's split callbacks (`setOnInterfaceConnected` / `setOnInterfacePeerSpawned`), each with its own user-setting gate. The polled state-observer's connect-trigger is gated to match. - `AutoAnnounceManager.start` (and the in-loop re-check) honour the `auto_announce_on_interval` toggle in addition to master. - `autoAnnounce()` itself bails on master-off as defense in depth. - SettingsView's Auto Announce card grows three sub-toggles + interval picker hides when the on-interval trigger is off. Pairs with reticulum-swift's onInterfaceAdded → onInterfacePeerSpawned / onInterfaceConnected split (see that repo). Ship-ready behaviour change on its own; no diagnostic logging in this commit. Co-Authored-By: Claude Opus 4.7 (1M context) * chore: bump reticulum-swift pin to 0.2.4 Picks up the onInterfaceAdded → onInterfacePeerSpawned/onInterfaceConnected split (reticulum-swift PR #14) that this PR's wiring requires. Co-Authored-By: Claude Opus 4.7 (1M context) * fix(AppServices): only resetTimer when announce was actually sent The polled state-observer's connect path was calling `autoAnnounceManager.resetTimer()` unconditionally — even when the TCP-reconnect gate had blocked the announce. Because `resetTimer()` restarts the periodic loop with a fresh `Next auto-announce in 3h (±1h)` schedule, every TCP reconnect on a flap-y network (mobile data ↔ WiFi, RNode in poor RF) would push the next interval-announce a full interval into the future without ever emitting one. The periodic schedule could be perpetually starved even though the user left "On interval" enabled and only disabled the reconnect trigger. Move the `resetTimer()` call inside the gate so it only fires when an announce actually went out. Greptile review feedback on PR #70. Co-Authored-By: Claude Opus 4.7 (1M context) * test(auto-announce): extract AutoAnnouncePolicy + cover trigger gates The auto-announce trigger gates were inlined as `defaults.bool(forKey: ...)` calls at seven sites across AppServices and AutoAnnounceManager, which made them impractical to unit-test without bringing up the full AppServices stack (transport, identity, router, …). Extract the gating decision into a pure value type, AutoAnnouncePolicy, that snapshots the four UserDefaults keys and exposes: - shouldFireOnInterval - shouldFireOnTcpReconnect - shouldFireOnPeerSpawned …all derived from the master enable plus the corresponding granular toggle. Routes the seven existing call sites through the policy so the inline string-key reads no longer appear in service code (which makes a typo-rename harder and gives every gate the same code path). Tests in AutoAnnouncePolicyTests cover: - Direct init stores all four flags. - Master off suppresses all three triggers regardless of granulars. - Each granular toggle gates its own trigger independently. - All-on / all-off boundary cases. - Empty defaults reports all-off (raw read behavior). - Snapshot is immutable after capture (catches future refactors that might keep a defaults reference). - register(defaults: true) produces the fresh-install all-fire baseline that SettingsViewModel.loadLocalSettings sets up. - Explicit false overrides registered default-true. 9 tests, all passing locally on iOS Simulator. Total suite went from 71 to 80 tests; no regressions. Co-Authored-By: Claude Opus 4.7 (1M context) * fix(auto-announce): attribute peer-child connected events to peer-spawned gate Reticulum-swift fires `onInterfacePeerSpawned` when an AutoInterface / BLEInterface / MPCInterface accepts a peer, then a moment later fires `onInterfaceConnected` for the peer's child transport's `.connected` transition. The previous gating treated the second event as a generic TCP-reconnect, so a user who turned the peer-spawned toggle off but left tcp-reconnect on would still get an announce on every peer-add — defeating the purpose of having a separate peer-spawned gate. Changes: - `AutoAnnouncePolicy.shouldFireOnInterfaceConnected(isPeerChild:)` new accessor that gates by `onPeerSpawned` for peer-children and `onTcpReconnect` for everything else (both still subject to `masterEnabled`). - `AppServices` tracks ids passed through `onInterfacePeerSpawned` in a `peerChildInterfaceIds` set, then queries it in the `onInterfaceConnected` handler to pick the right gate. - Diagnostic log line distinguishes the two attribution paths so a future investigation can tell whether an announce came from the tcp-reconnect or peer-child-reconnect branch. Tests cover the four corners of the cross-trigger matrix plus the master-off override: - peer-child + peer-spawned-off + tcp-reconnect-on → does NOT fire - peer-child + peer-spawned-on + tcp-reconnect-off → fires - non-peer-child + tcp-reconnect-on / off → fires / not - master off → never fires - all-on / all-off across peer-child boundaries Greptile review feedback on PR #70 (4/5 confidence comment about peer-child overlap). Co-Authored-By: Claude Opus 4.7 (1M context) * fix(auto-announce): make peer-child attribution race-free The peer-spawned and connected callbacks fire from independent reticulum-swift Tasks. The previous implementation used MainActor- isolated record / lookup, which meant both operations had to await an actor hop. Swift's task scheduler doesn't guarantee record-before-lookup ordering between unrelated Tasks, so a fast peer-add → child-connect sequence could in theory mis-attribute the connected event to tcp-reconnect instead of peer-spawned (the user-facing bug fixed in the prior commit). Replace the MainActor-isolated Set with a synchronous, lock-protected PeerChildInterfaceRegistry (OSAllocatedUnfairLock-backed). The peer- spawned closure now records on its first line, *before* any await suspension, so the record is committed before any subsequent onInterfaceConnected for the same id can possibly run its attribution lookup. The connected closure's lookup is also synchronous, so attribution is correct regardless of how the schedulers interleave the rest of the closure bodies. Tests: - PeerChildInterfaceRegistryTests: empty / record-then-contains / idempotent / reset / immediate-visibility on same thread. - testConcurrentRecordAndContainsObservesAllPriorRecords: 1000-way concurrent record+contains stress, asserts no crash and full visibility after group completes. Total suite: 90 tests, all passing. Greptile review feedback on PR #70 (4/5 confidence comment about Task ordering between MainActor hops). Co-Authored-By: Claude Opus 4.7 (1M context) * chore(greptile): iteration 1 — applied 2, rejected 0 Snapshot dictionary keys before mutating during iteration in PacketTunnelProvider: - applyConfigsLocked() stale-entry teardown: collect stale ids via filter() before the loop instead of iterating currentTCPs.keys while teardownTCPConnectionLocked + removeValue mutate it. - wake() reaper: iterate Array(self.tcpConnections.keys) instead of the live Keys view while teardownTCPConnectionLocked mutates the same dictionary. Both paths run on configQueue (the only mutator), but Swift's Dictionary.Keys is documented as a live view and mutation during iteration is undefined behavior — can silently skip entries or crash. Both fixes are inert for the single-TCP case but matter as soon as 2+ TCPs are active and a config-change or wake event fires. Co-Authored-By: Claude opus-4-7-1m * chore(greptile): iteration 1 — applied 1, rejected 0 Roll back tcpInterfaces[entityId] and defer tcpEndpoints[entityId] until after transport.addInterface succeeds. Without this, a transient addInterface throw left both dictionary entries populated for a dead, un-attached interface; the next connectTCPInterface call with the same endpoint hit the idempotency guard at the top of the function and silently no-op'd, breaking self-healing reconnects until the user manually edited host/port. Greptile thread 2 (the matching skip in InterfaceManagementViewModel. applyChanges) is satisfied by this same fix — once tcpEndpoints reflects only successfully-applied endpoints, the VM's `tcpEndpoints[id] == desired` guard correctly distinguishes "running cleanly" from "stale dead entry waiting to retry". Co-Authored-By: Claude claude-opus-4-7[1m] * chore(greptile): iteration 2 — applied 1, rejected 0 Extend the connectTCPInterface write-after-success + rollback pattern to the three remaining tcp-server init sites: both initialize() overloads and reinitializeConnection(). Without this, an addInterface throw during init left tcpInterfaces["tcp-server"] and tcpEndpoints["tcp-server"] populated with a dead interface; reconnectTCPOnly delegates to connectTCPInterface(entityId: "tcp-server", ...) which then silently no-op'd on a same-address retry through the new idempotency guard. For the two initialize overloads, the catch block preserves the "non-fatal" semantics (init proceeds without TCP, no rethrow) but now also clears the partial dictionary writes so a later reconnectTCPOnly retry isn't stuck. For reinitializeConnection — which had no catch and propagates errors to its caller — the new do/catch rolls back and rethrows, mirroring connectTCPInterface.

The 17 actions, log shape (`event=key=value`), and whitespace-escape rules match Android byte-for-byte so the python orchestrator's regexes work cross-platform. - Sources/ColumbaApp/Test/TestController.swift — singleton coordinating the test-action surface; binds to live AppServices/router/interface repository, observes inbound LXMF + delivery-state via a relay delegate, emits structured os_log lines under subsystem `network.columba.app.test` / category `harness` so idevicesyslog filters cleanly. - Sources/ColumbaApp/Test/TestURLHandler.swift — `lxma-test://?` dispatcher; mirrors Android's TestReceiver `when (action)` switch, routes to TestController. Wired into ColumbaApp.swift's `.onOpenURL` with a `#if DEBUG` guard. - Both files are wrapped in `#if DEBUG` so they compile out of release `.ipa`s. Defense in depth: every entry trips an `assertionFailure` with a release-misconfig message. Verified empirically — release build's binary contains zero references to TestController / TestURLHandler / harness log strings. - `lxma-test` URL scheme registered in Info.plist alongside `lxma`. The scheme stays present in release builds (no per-config plist on this project) but is harmless because no code in release handles it; the release `.onOpenURL` `#if DEBUG` block compiles to a guard-pass and the URL falls through. The Python orchestrator at ~/.claude-runner/columba-harness/smoke_test_ios.py drives this surface end-to-end (devicectl URL dispatch + idevicesyslog tail) and is the iOS sibling of smoke_test.py. Co-Authored-By: Claude Opus 4.7 (1M context) * fix(test-harness): unbreak release-guard + add file-based event log Two bugs that prevented end-to-end smoke runs against a physical iPhone: 1. assertionFailure_releaseGuard() was calling assertionFailure(...) UNCONDITIONALLY in both TestController.swift and TestURLHandler.swift. That's exactly inverted from the intent — `assertionFailure` ALWAYS crashes in DEBUG builds. So every URL dispatch and every public handler entry crashed the app on the guard before any logic ran. Mirrors the Android side's `check(BuildConfig.DEBUG)` semantics: crash only when DEBUG is FALSE. New impl wraps the body in `#if !DEBUG ... #endif` so it's a no-op in normal debug builds and a hard crash if a release ever gets misconfigured to compile this file in. 2. TestLog.emit() now ALSO writes each line to `Documents/test_log.txt`, prefixed `seq= ts=`. Reason: the Python orchestrator originally tailed device syslog via `idevicesyslog`, but iOS 17+ moved live-syslog behind the new CoreDevice / RemoteXPC tunnel that libimobiledevice can't speak. `pymobiledevice3` would work but needs a developer-tunnel daemon. The orchestrator now polls Documents/test_log.txt via `xcrun devicectl device copy from --domain-type appDataContainer`, which works out of the box and is more robust (no race window, survives disconnects). os_log writes are kept for human readers. Verified end-to-end: smoke_test_ios.py runs the propagated_bidirectional scenario all the way through interface setup, propagation-node config, HAS_PATH=1, SEND_PROP, msg_sent. (Stalls at OUTBOUND-never-advances-to- PROPAGATED — separate LXMFSwift outbound state-machine issue, NOT a harness bug. Diagnostic for that lands in a follow-up.) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.7 (1M context) * test(harness): add lxma-test://dump_log for OSLogStore extraction iOS 17+ moved live syslog behind the new CoreDevice / RemoteXPC tunnel that libimobiledevice can't speak, so the smoke harness couldn't observe library-internal events on the device. Added a debug-only `dump_log` URL action that uses OSLogStore to extract recent unified-log entries from the app process and forwards them into Documents/test_log.txt as `lib_log subsys=… cat=… level=… msg=…` lines that the orchestrator can parse with its existing devicectl copy-from poll mechanism. Filter defaults to `(com.columba.core, net.reticulum.lxmf)` × (Propagation, Sync, LXMRouter, Stamper, Identity, PropagationNodeManager) to surface just the propagation-path observability we need to diagnose stuck `state=OUTBOUND` failures. `?since=` sets the window (default 120s); `?cat=` overrides categories; `?cat=*` disables category filtering. Critical first finding when wired up: processOutbound IS running and calling sendPropagated; the failure is `LXMRouter` emitting "Delivery failed: No path available to destination, retrying in 15s/120s" because `pathTable.lookup(destinationHash: nodeHash)` returns nil for the propagation node hash even though `pathTable.hasPath(for:)` returns true on the same hash from the harness. Likely actor- isolation race or stale-snapshot bug in the path-table view; needs deeper investigation in LXMF-swift / reticulum-swift. Sticks to existing test-surface contract — `lib_log_done count=` / `lib_log_err reason=` reply tokens; debug-only via the existing `#if DEBUG` source-set isolation. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.7 (1M context) * fix(harness): wire iOS PROPAGATED smoke end-to-end Three bug-fix-and-instrument changes to make the PROPAGATED self-send round-trip pass on iOS. Mirrors the Android smoke pipeline shipped in PR #882. 1. TestRelayDelegate retention. LXMRouter holds the delegate weakly (LXMRouter.swift `weak var delegate`); attachDelegate handed in a stack-local relay that immediately deallocated, leaving the router with a nil delegate and no didUpdateMessage callbacks for outbound state changes. Pin the relay to TestController.attachedDelegate. 2. set_prop_node now goes through PropagationNodeManager.selectNode (via TestPathBridge.selectPropNode) instead of router.setOutboundPropagationNode. The manager is the only path that wires the announce-derived stamp cost into the router; the bare router setter left cost=0 and sendPropagated shipped a random stamp that lxmd rejected with ERROR_INVALID_STAMP. selectNode also now (a) reads stamp cost from pathTable.appData when knownNodes is empty and (b) waits up to ~5s for either source to populate, covering the smoke-test race where set_prop_node fires immediately after add_tcp_client (before the announce arrives). 3. PropagationNodeManager.processPathEntry re-applies the stamp cost to the router whenever an announce updates the currently-selected node, so a delayed announce can correct an earlier cost=0 setting. Plus instrumentation: dump_log now emits each OSLog entry's actual recorded timestamp (`entry_ts=`) alongside the dump-time `seq=N ts=` prefix, and includes `network.columba.Columba` in the allowed-subsystem set so app-side managers (PropagationNodeManager) show up. Direct + opportunistic self-send scenarios are still WIP — they require LXMRouter-level loopback for self-addressed packets (single device can't actually transit a packet to itself through the network) which is a future stage. PROPAGATED works today via the lxmd round-trip. * chore: bump LXMF-swift to a3e5b00 (DIRECT identify-drop fix) * chore(deps): pin reticulum-swift to fix/link-data-no-header2-conversion reticulum-swift @ d19919a — drops incorrect HEADER_2 conversion of link DATA packets that broke multi-hop DIRECT delivery (state=SENT but the echo bot never received the message). Mirrors python RNS/Transport.py :1063, 1122-1130 — link DATA always sends HEADER_1 to the link's attached_interface, never through path-table lookup.

The ticker is driven by an internal Task, NOT URL dispatch, so it keeps emitting even when URLs are wedged. If ticks ALSO stop, the OS suspended/killed the app. If ticks keep coming with state != .active, the app went background. If ticks keep firing AND state stays .active but URLs still don't reach the handler, the wedge is below SwiftUI (CoreDevice tunnel / launch services). Last is the smoking gun pattern. Field finding from this commit's first run (2026-05-10): iter 1: 3/3 PASS iter 2: 3/3 PASS iter 3: 0/3 FAIL — "TCP client interface ADD never confirmed" iter 4: total wedge — TestController never answered get_dest After the wedge, even `devicectl device copy from` hangs for 30+s, which proves the wedge is at the **CoreDevice tunnel layer**, not the app's URL handler. The iPhone-side dev tunnel (RemoteServiceDiscovery) goes degraded after rapid `process launch --payload-url` bursts. Recovery: pkill devicectl + relaunch app via process launch (which still works because process control rides a different RSD service).

Co-authored-by: torlando-tech Co-authored-by: Claude Opus 4.7 (1M context) * fix(tunnel): guard applyTunnelModeToInterfaces(active:false) against initial .invalid VPN state iOS emits an `.invalid` / `.disconnected` VPN status notification on every cold start — fired by `TunnelManager.onStatusChange` regardless of whether the user has enabled Background Transport, because the session machinery probes whatever is currently loaded. The previous code unconditionally scheduled `applyTunnelModeToInterfaces(active: false)` via the 5s debounce, which iterated every TCPInterface and called `endTunnelMode()`. `endTunnelMode()` in reticulum-swift 0.3.0 is NOT idempotent (TCPInterface.swift:257-269): it unconditionally tears down the working NWConnection (via `transport?.disconnect()` -> nil) and re-runs `setupTransport()`. Calling it on an interface that was never in tunnel mode (outboundHook == nil) is destructive — it kills the live socket Step 7 brought up moments earlier. Reproduced 2026-05-11 on smoke run iter1 against `feat/multi-tcp-tunnel @ 0f7cf3e`: all 4 scenarios FAILED at the earliest `send_*` step. has_path returned 1 for both PN and bot (path table populated via inbound announces), but outbound sends never advanced past `state=OUTBOUND`. Console showed `[TUNNEL] disabled tunnel mode` ~5s after cold start with no prior `[TUNNEL] enabled` line, confirming the debounce was tearing down TCP without ever having activated it. Fix tracks an `isTunnelModeActive` bool. The active=false branch guards on it and returns early if tunnel mode was never activated. Mirrors the "undo what you did" contract.

That moves the contract upstream, so the `isTunnelModeActive` bool guard added in `c0d2213` is no longer necessary — the `endTunnelMode()` calls in `applyTunnelModeToInterfaces(active: false)` are now safely no-ops when fired on never-tunneled interfaces (e.g. the initial `.invalid` VPN-status notification on every cold start). Removed: - `isTunnelModeActive` field declaration + doc - `isTunnelModeActive = true` write in the active=true branch - `isTunnelModeActive = false` write in the active=false branch - The `guard isTunnelModeActive else { return }` short-circuit Build verified: xcodebuild for iOS Simulator BUILD SUCCEEDED. The port-deviations.md note for reticulum-swift's tunnel API spelled out that this Columba-iOS workaround should be deleted on the next deps bump — this is that deps bump.

Reverted just the Columba-side workaround removal here as an A/B test — same HEAD otherwise (0.3.1 deps preserved). If smoke goes 5/5 again on this commit, it proves 0.3.1's upstream `outboundHook != nil` guard is necessary but not sufficient; the Columba workaround was suppressing something the upstream check doesn't catch. Diag.log from the failing iter shows `[TUNNEL] disabled tunnel mode` fires at +5s cold-start (the .invalid debounce expiring) but Step 7 reports "starting 0 enabled interfaces" before that, meaning `tcpInterfaces` is empty when the disable iterates. So whatever the workaround was suppressing isn't `endTunnelMode()` being called on live interfaces — it's something else in the same code path or a related side effect. Investigation continues; the workaround stays in until the actual mechanism is identified. This restores the `isTunnelModeActive` field, the `= true` write in the active branch, and the `guard isTunnelModeActive else { ... }` short-circuit in the inactive branch. reticulum-swift 0.3.1 is kept (`Package.swift` / pbxproj minimumVersion / Package.resolved unchanged) — the upstream guard is still a correctness improvement even if it isn't load-bearing for this specific Columba bug.

Used by the Phase A `suspended_notification` smoke scenario (in `smoke_test_ios.py`) to assert whether a system-level notification was posted while the app was suspended: compare each notification's `delivery_ts` against the orchestrator's `T_foreground` wall-clock to distinguish "delivered during suspension" (notification fired from the extension, the goal) vs. "delivered post-foreground" (app caught up by draining the queue, what the current "dumb pipe" NE architecture produces). The scenario is expected to FAIL on the current branch — that failure IS the gate signal that Phase B (push destination-hash filter + UNUserNotificationCenter call into ColumbaNetworkExtension) hasn't shipped yet. Phase A's purpose is exposing the gap that the existing smoke obscured by foregrounding before checking the DB. Build verified: xcodebuild iOS Simulator BUILD SUCCEEDED.

Lets the scenario detect the permission-missing branch and fail with a clear `iOS notification permission not granted (auth=…)` message instead of "no notifications, cause unknown." - `lxma-test://request_notif_permission` — calls `UNUserNotificationCenter.requestAuthorization` (iOS shows the system "Allow notifications?" prompt on first run) AND sets `notifications_enabled` + `notify_received_message` to true in UserDefaults so `NotificationService.postMessageNotification` won't short-circuit on the pref guard. First run after a fresh install: orchestrator drives this URL, iOS shows the system prompt, Tyler taps Allow once on the phone. From then on the grant is persisted and the scenario runs unattended. Build verified: xcodebuild iOS Simulator BUILD SUCCEEDED.

With Darwin notifications unable to wake a suspended host app (Apple DTS forum 769398), `NotificationService` never fired on inbound LXMF traffic until the user manually foregrounded the app. This commit moves the minimum amount of Reticulum awareness into the `NEPacketTunnelProvider` to fix that gap: - `AppServices.publishLocalDestinations()` writes the `transport.registeredDestinationHashes()` set to App Group prefs and posts a Darwin reload notification. Called at the end of both `initialize` overloads and after `initializeBaseStack` — every place where a destination is freshly registered. `switchIdentity` delegates to the second `initialize` overload so identity switches are covered too. - `PacketTunnelProvider` decodes the published hex hashes into a `Set` on `configQueue`, observes the reload Darwin notification, and consults the set in `handleTCPData` for every deframed packet. Matching packets get an `UNUserNotificationCenter` request posted under the host app's bundle identity so iOS shows a banner / lock-screen alert even while the host app is suspended. The filter inspects only unencrypted header fields (header type byte + destination_hash at offset 2 for HEADER_1 or offset 18 for HEADER_2, verified against `Reticulum/RNS/Packet.py:Packet.unpack`); crypto and full LXMF decode stay in the host app. Fires on DATA+CONTEXT_NONE (OPPORTUNISTIC LXMF arrivals) and LINKREQUEST (DIRECT delivery initiation, the only DIRECT-flow packet addressed to our delivery hash); ANNOUNCE and PROOF are skipped. Notifications inherit the host app's authorization grant — extensions sit in the container app's notification domain (Apple DTS engineer Quinn) — so no extension-side `requestAuthorization` is needed.

Adds two `lxma-test://` actions that the harness can call to flip Background Transport on programmatically (matching the Settings toggle's behaviour byte-for-byte: it persists `tunnelEnabledKey` so a cold restart auto-resumes the tunnel, then kicks `TunnelManager.start()` and waits up to 30s for `.connected`). - `enable_tunnel` — emits `tunnel_enable state=` - `get_tunnel_status` — emits `tunnel_status state=` `TestTunnelBridge` keeps the test surface ignorant of `TunnelManager`'s real type (it only exists under `ENABLE_NETWORK_EXTENSION`), so the file still compiles in build configurations where the extension is turned off. The bridge closure lives in `TestURLHandler.bind`, guarded by the same compile flag.

Fresh installs that never visit Settings silently had every one of those keys defaulting to `false` at the raw `UserDefaults.bool(forKey:)` level, because `register(defaults:)` had never run. Concrete symptom: `AppServices.configureTransportCallbacks`'s `onInterfaceConnected` hook calls `AutoAnnouncePolicy.current()`, sees `masterEnabled = false`, and logs `[AUTO_ANNOUNCE] onInterfaceConnected(...) — master toggle off, skipping`. The phone never auto-announces on TCP reconnect, so rnsd loses the phone's path the moment the TCP socket cycles. From the bot side, this manifests as `Got packet in transport, but no known path to final destination . Dropping packet.` Every bot→phone DIRECT/OPP delivery silently drops because rnsd has nothing to route to. Lifts the registration to a static `SettingsViewModel.registerLocalDefaults(into:)` method, called from `ColumbaApp.init()` before `AppServices` reads any of the keys. `register(defaults:)` only sets fallbacks for keys without explicit values, so it remains harmless to call from `loadLocalSettings()` too (which still does, so the view is self-sufficient in isolation).

The `active: false` branch already guarded against this via `isTunnelModeActive`; the `active: true` branch did not. Each redundant `.connected` callback then called `beginTunnelMode` on every `TCPInterface` again, which re-installs the outbound hook and resets the transport pointer — racing any in-flight LXMessage send. The visible symptom in the diag is the matching pair: [TUNNEL] enabled tunnel mode on N TCP interface(s); ... [TUNNEL] enabled tunnel mode on N TCP interface(s); ... logged twice within the same second, followed by the LXMF state machine stalling (e.g. a queued DIRECT send sits in OUTBOUND for 30+s before the bot eventually receives the LINKREQUEST). Symmetric guard with the disable branch: bail with a noisy diag log on the redundant `.connected` event. Verified on-device: after this commit the diag shows exactly one `[TUNNEL] enabled tunnel mode` followed by `[TUNNEL] skipping enable — already active` for each tunnel-up transition, instead of two unguarded enables. Mid-session `enable_tunnel` test-action call behaves predictably afterwards.

Both connect to the same rnsd; rnsd sees two clients with independent paths to . The old architecture had a fatal seam at the foreground-to-tunnel handoff: the app-owned socket closed, rnsd removed the path entry attached to it, and the extension's new socket had no announce yet because `TCPInterface.beginTunnelMode` keeps state=.connected (no notifyStateChange, so auto-announce-on-tcp-reconnect doesn't fire). Bot→phone packets then bounced as `Got packet in transport, but no known path to final destination ` for the entire suspend window — Phase B's filter had nothing to fire on. New architecture: * `Sources/ColumbaApp/Services/TunnelTCPInterface.swift` — new `NetworkInterface` implementation. Outbound: HDLC-frames data and calls `TunnelManager.sendFrame(..., entityId=TUNNEL_TCP_INTERFACE_ID)`. Inbound: receives via `ExtensionFrameReader`'s `onTCPFrameReceived` callback when the tag matches. * `AppServices.registerTunnelInterface()` — fires on tunnel .connected. Creates and registers the TunnelTCPInterface, mirrors the foreground TCP's host/port, publishes the endpoint to a new App Group key `tunnelTCPEndpointsKey`, then sends `sendAllAnnounces` (broadcast) followed by a 100ms-delayed tunnel-only re-announce. The tunnel-only follow-up pins rnsd's last-write-wins path table to the tunnel socket so the foreground socket dying on suspend doesn't strand the path. * `AppServices.deregisterTunnelInterface()` — fires on .disconnected / .invalid (5s debounce). Removes the interface from the transport and clears the App Group endpoint list. * `PacketTunnelProvider.loadInterfaceConfigs` — reads `tunnelTCPEndpointsKey` first. When present + non-empty, it's the only source of TCP entries; otherwise falls back to the legacy `interfacesKey` TCP parsing (preserves the multi-TCP tunnel commit's behaviour for older builds). Adds a Darwin observer for the matching `tunnelTCPEndpointsChangedNotificationName` so the extension reapplies without a tunnel restart. * `AppServices.connectTCPInterface` — no longer calls `beginTunnelMode` on newly-added foreground interfaces. They stay foreground-only. `applyTunnelModeToInterfaces(active:)` is orphaned (no callers); left in place for now alongside the `isTunnelModeActive` guard until a follow-up gut. * `AppServices.ExtensionFrameReader.onTCPFrameReceived` — only frames tagged `TUNNEL_TCP_INTERFACE_ID` route into the transport. Frames from any other entity ID get dropped, since the foreground TCPInterfaces receive their own inbound via their app-owned NWConnection — accepting the extension's duplicate would double-process every packet. Verified end-to-end: the suspended_notification smoke scenario posts a DIRECT message from a Mac-side pinger to the phone every 10s. When the host app is backgrounded, the tunnel TCP socket stays alive, rnsd routes the ping via the tunnel path, the extension receives the LINKREQUEST + DATA packets, and `maybeScheduleNotification(for:)` matches each against `localDestinationHashes` and posts a UN notification. Result: `suspended_notif_count: 2` during a 30s suspend window. Phase B is now validated end-to-end.

That assumption broke at `dc1024b` when the `SettingsViewModel.registerLocalDefaults` call moved to `ColumbaApp.init()` so the on-reconnect announce fires for fresh installs that never touch Settings. The XCTest host loads the @main App before running tests, so `ColumbaApp.init` executes and registers the four `auto_announce_*` toggles to `true`. NSUserDefaults' registration domain is shared across every UserDefaults instance in the process — including `UserDefaults(suiteName:)` scratch defaults — so the per-test suite inherits the fallbacks. Renamed the test to `testEmptyPerSuiteInheritsProcessWideRegistrationAsAllOn` to reflect the actual contract being pinned: the app-init registration *must* leak to all UserDefaults instances, because that's exactly what makes the on-reconnect announce fire on a fresh install. A future refactor that drops the app-init registration call now fails this test loudly instead of silently regressing every fresh install to no-auto-announce. The two adjacent tests (`testRegisterDefaultsTrueProducesAllFireForFreshInstall`, `testExplicitFalseOverridesRegisteredDefaultTrue`) still validate the per-instance `register(defaults:)` mechanics + explicit-write override semantics on the per-suite. Together the three tests cover the full registration-domain contract.

On-demand always-connect rules in the VPN profile (TunnelManager.install + start). iOS now keeps the tunnel up across wake/sleep, network changes, and restarts it after the system tears it down under memory pressure. Existing profiles are migrated on next start(); disable() clears the rules so stopVPNTunnel() doesn't silently bounce back on. 2. Status-observer restart loop in AppServices (scheduleTunnelRestartIfNeeded). When the tunnel transitions to .disconnected after having been .connected (and the user's tunnelEnabledKey is still true), schedule a restart with doubling backoff (1s start, 300s cap). This is the belt to on-demand's suspenders — iOS doesn't always re-fire on-demand promptly. Gated on tunnelHasBeenConnectedOnce so the initial boot .disconnected firing doesn't race the auto-start path. 3. Don't auto-clear tunnelEnabledKey on transient launch failures. The previous auto-start cleared the pref on a 30s no-connect timeout, permanently disabling background transport on any transient blip — the empirical "tunnel dead for 10h" state was reproducibly caused by this. The restart loop now handles transient failures; only the user's explicit toggle-off clears the pref. Verified on-device: cold launch from saved pref reaches .connected with both interfaces (foreground + NE-owned) present in rnsd's client list, backgrounding leaves the NE-owned connection intact (only the foreground socket dies), and foregrounding restores the dual state without any tunnel drop. Does NOT yet solve "notifications fire during backgrounding" — rnsd's path drift to the foreground socket still causes inbound packets to be dropped while the app is suspended. Path management is the next commit.

Verified on-device with a controlled 50s background window: the NE went from zero matches (path drift to dead foreground socket) to four `[EXT/NOTIF] match` + `UN add ok` entries in the same interval — two DIRECT LINKREQUEST matches for the phone's delivery dest plus two OPPORTUNISTIC matches for a second local destination. Phase B notifications now fire reliably while the app is suspended for the duration of the RNS path TTL. Sustained suspension (path TTL > foregrounded re-announce interval) still needs NE-side periodic re-announce — a separate change that requires the delivery identity in the App Group keychain. Adds public AppServices.announceViaTunnel() wrapping the existing private sendAnnounceViaTunnel — needed because the call site is the .background scenePhase handler in ColumbaApp, which lives in the App target and can't reach private AppServices methods.
