fix(connections): hide the replay demo entry when its capture asset is absent - #6692
Merged
Conversation
The burningmesh.fromradio capture that ReplayRadioTransport replays is generated locally by the burningmesh-replay tool and is not checked in, so no clean-checkout build carries it. createReplayTransport() therefore always fell back to MockRadioTransport, leaving the USB pane with two Demo Mode entries that behaved identically — one of them advertising a replay it cannot perform. Harmless while Demo Mode was debug-only; user-visible once it became reachable in release builds. Gate the entry on a new isReplayTransportAvailable capability, probed once on Android from the APK assets and false on desktop, threaded to the picker as a second flag on GetDiscoveredDevicesUseCase.invoke and nested inside the existing mock gate. Declared as a val rather than a fun: asset presence is fixed for the process lifetime, and RadioInterfaceService sits exactly at detekt's 11-function interface cap. isAddressValid is deliberately unchanged — a persisted "r" address still resolves and falls back to mock, so hiding the entry cannot strand a saved selection.

59-63: 📐 Maintainability & Code Quality | 🔵 Trivial | 🏗️ Heavy liftMove the replay visibility policy to
commonMain.
showMock/showReplaygating is pure discovery policy, but this change adds it to the Android use case alongside the common discovery path. Keep USB enumeration and Android permission handling inandroidMain. Extract the virtual-entry visibility decision into a sharedcommonMainhelper so the platform paths cannot diverge.As per path instructions, “Do not place business logic in androidMain; business logic belongs in commonMain.”

The Demo Mode / replay entry policy was built independently in the common and Android discovery paths, so the two could drift — this change had just added a second flag to both. Extract it into virtualDeviceEntries() beside the existing shared TCP helpers in commonMain; business logic does not belong in androidMain. Android also picks up the safe label resolution the common path already had: getStringSuspend wrapped in safeCatchingAll with an English fallback, instead of a bare getString that throws if the resource cannot resolve. Raised by CodeRabbit on #6692. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The ScannerViewModel harness accepted showMock/showReplay and ignored both, so its fake returned identical devices for every combination — a ViewModel test could pass while the ViewModel requested the wrong visibility. Record the requested pairs and assert against them, which is the only coverage that pins the capability-to-picker wiring this branch introduces. Also assert entry identity rather than list size in testEmptyResolvedListIncludesMock: `size shouldBe 2` holds for any two entries, including a regression that dropped Replay for a duplicate Mock.

…hes the list Review follow-ups on the Demo Mode release path. The simulator hands out packet ids from four concurrent callers — the seed pass, the live-telemetry ticker, the delayed replies and the delayed acks — through an unsynchronised counter, so two frames could carry the same id. That is not cosmetic in this app: the message and node lists are keyed by packet id and a duplicate key has crashed them before, on exactly the screens a store reviewer has open while the demo runs. The counter is now atomic. `replyJobs` had the same problem from the other direction: `close()` iterated and cleared it while `handleSendToRadio` was still appending, which is a ConcurrentModificationException waiting for a disconnect that overlaps a sent message. All of the transport's coroutines — ticker, replies and the acks that were not tracked at all — now live in one atomic reference that `close()` drains in a single swap. The Demo Mode gate assertion also had to be made able to fail. Asserting on `showMockTransport` alone would pass even if the ViewModel stopped feeding the gate into the device-list query, on the one feature this branch exists to deliver. It now asserts on the requests the use case actually received — one per gate value, in order — using the `discoveryRequests` recorder that #6692 added to the harness for this same reason. Verified by mutation: reverting `showMockTransport` to a one-shot sample fails it. 🛠️ - Atomic packet-id counter, `trafficStarted` CAS, and one atomic job list covering the ticker, replies and acks; `close()` drains it atomically. - Clamp the drifting voltage to a resting-cell floor. Ticks are 20s, so the old unbounded slope reported a negative voltage after ~2.2 hours while the battery percentage on the line above was already coerced into 5..100. 🧹 - `MockRadioTransportTest`: assert RSSI presence and variation separately rather than `rx_rssi ?: 0 != 0` — 0 dBm is a legal strong reading, so the sentinel-zero form did not prove what its message claimed. Same for SNR variation, noting the proto gives it no presence bit. - Widen the packet-id uniqueness check from text frames to every frame. - New `close stops the simulated mesh` test: the natural regression for the job-tracking fix. Verified by mutation — a no-op `close()` fails it. Rebased onto #6692, which landed the replay-asset gate on the same surface. Union, not either side: the gate stays reactive (that is the point of this branch — the list must notice a mid-session unlock) while #6692's `showReplayTransport`, its 3-arg `GetDiscoveredDevicesUseCase.invoke` and its asset gating are kept intact. `MockTransportAddressAdmissionTest`'s fake factory gained the new `isReplayTransportAvailable` member. Testing Performed - `spotlessApply spotlessCheck detekt assembleDebug test allTests kmpSmokeCompile` green on the rebased tree (an earlier run caught a real iOS-only compile break in the admission test's fake factory). - Zero `<failure>` tags across every test-results XML in the tree. - Mutation-checked both new tests fail when the code they guard regresses.

The Connections screen's USB pane offered two virtual devices behind the Demo Mode gate — "Demo Mode" and "Demo Mode (Replay)" — but the
burningmesh.fromradiocapture thatReplayRadioTransportneeds is generated locally by the burningmesh-replay tool and is not checked into the repo, so no clean-checkout build carries it.createReplayTransport()always logged "asset is missing — falling back to mock" and returned a plainMockRadioTransport, leaving two picker entries with identical behaviour, one of them advertising a replay it cannot perform. That was harmless while Demo Mode was debug-only; it became user-visible once Demo Mode was made reachable in release builds.🐛 Bug Fixes
DeviceListEntry.Replayin builds that do not carry the capture asset, so the picker no longer shows a second Demo Mode entry that silently degrades to the first.🛠️ Refactoring & Architecture
isReplayTransportAvailabletoRadioTransportFactoryandRadioInterfaceService.AndroidRadioTransportFactoryprobes the APK assets once viaby lazy(an empty asset counts as absent, matchingcreateReplayTransport's own guard);DesktopRadioTransportFactoryandNoopRadioInterfaceServicereturnfalse;SharedRadioInterfaceServicedelegates to the factory.valrather than afun. Asset presence is fixed for the process lifetime, so aStateFlowwould be machinery wrapping a constant — andRadioInterfaceServicesits exactly at detekt'sTooManyFunctionsinterface cap (11), where a twelfthfunfails:core:repository:detektwhile properties are not counted.GetDiscoveredDevicesUseCase.invoke(showMock, showReplay, resolvedList)and threaded the flag fromScannerViewModel. The two flags are nested —showReplayis only honoured insideshowMock— so "replay offered without Demo Mode" is unrepresentable in the picker. Kept as a parameter rather than injectingRadioInterfaceServiceintoCommonGetDiscoveredDevicesUseCase, which today takes only data sources; as a parameter the use case stays a pure function of its inputs, exactly likeshowMock.JvmGetDiscoveredDevicesUseCaseinherits the new signature unchanged.virtualDeviceEntries()incommonMain, beside the existing TCP discovery helpers. The common and Android paths previously built the Demo Mode entries independently and could drift; Android also picks up the safe label resolution the common path already had (getStringSuspendundersafeCatchingAllwith an English fallback, instead of a baregetStringthat throws when the resource cannot resolve).FakeRadioInterfaceServiceexposes the flag as avarso future replay-gated tests can flip it.Reviewer note
BaseRadioTransportFactory.isAddressValidis deliberately not tightened: it still accepts anr…address wheneverisMockTransport()is true. Requiring the asset there would invalidate a persisted replay selection in a build that later lost it, whereas the existing fallback keeps that user on a working virtual device. Hiding the picker entry is the fix; the fallback stays as the safety net.Testing Performed
