A long tail of command handlers sits at 82-89% with fully covered lines but uncovered guard branches; closing those is branch work, not line work. + +## Architecture + +### `EventLoopHostedService` (new, `RustPlusBot.Abstractions/Hosting/`) + +Every feature hosted service is the same object: a set of event-bus consume loops started in `StartAsync` and joined in `StopAsync`. Today each one hand-rolls a `CancellationTokenSource`, one `Task?` field per loop, one `ConsumeXAsync` method per loop with an identical try/catch, and its own `LogHandlerFailed` partial. + +Replace with an abstract base: + +```csharp +public abstract class EventLoopHostedService(IEventBus eventBus, ILogger logger) + : IHostedService, IDisposable +{ + protected abstract IEnumerable Loops { get; } + protected EventLoopRegistration Loop( + string name, Func handle) where TEvent : notnull; +} +``` + +The base owns the CTS, the `Task.Run` fan-out, the join, the `OperationCanceledException` swallow, the broad-catch loop-faulted log, and the per-event handler-failure log. Subclasses shrink to a constructor and a `Loops` table. + +This resolves cluster 1 and the S1192 smell together, and makes the loop machinery covered by one test class instead of five. + +**Deliberate behaviour change.** `EventBusConsumption`'s own remarks warn that a hosted service which subscribes inside its background `Task.Run` is only subscribed once that task is scheduled, and drops every event published in the meantime. `SwitchesHostedService` and its siblings do exactly that today. The base will call `IEventBus.SubscribeAsync` eagerly and synchronously in `StartAsync`, then hand the stream to `ConsumeAsync` inside `Task.Run` — the pattern the remarks prescribe. This closes a real start-up drop window. + +### `RustPlusBot.Features.Devices` (new project) + +Switches, StorageMonitors and Alarms are parallel assemblies with `internal` types and no shared home, which is why their pairing, posting and relay code is copied rather than shared. Add `src/RustPlusBot.Features.Devices/` referencing Abstractions, Domain, Persistence, Discord, Workspace and Localization; the three feature projects reference it. + +It holds: + +- `PairedDeviceCoordinator` — the confirmed-identical pairing flow (pending dictionary, exists-guard, prompt post, race-guarded accept, dismiss). Two hooks cover every difference between the Switch and StorageMonitor versions: a `DefaultNamePrefix` string and a `RenderAccepted(TEntity, CultureInfo)` method returning the embed and components. +- `DiscordDeviceChannelPoster` — the shared ensure/edit/delete body behind the three `Discord*ChannelPoster` types, which become thin typed wrappers. +- The shared relay guard used by `SwitchStateRelay`, `EventRelay` and `PlayerEventRelay`. + +### `PairedDeviceStore` (new, `RustPlusBot.Persistence`) + +Base for the 19-line block shared by `SwitchStore` and `StorageMonitorStore`. + +### Smaller extractions + +- `StorageMonitorEmbedRenderer` drops its inline duration formatting and calls `DurationFormat.Compact`. +- The 27-line embed shell shared by the two clan renderers moves to a private helper in `Features.Clans/Messages/`. +- `SwitchStateRelay`, `VendingModule` and `AlarmComponentModule` get their self-duplicated blocks extracted into local helpers. + +### Smell refactors + +`WorkspaceReconciler` (both methods), `ClanSnapshotDiffer` and `DatasetValidator` split into named private steps. The split is chosen so each step is independently callable, which turns complexity reduction into coverage surface. + +`MarkerReply`, `MapRenderer` and the generator's `Program` take a parameter record instead of 8-9 positional parameters. + +## Sonar configuration changes + +In `.github/workflows/Sonar.yml`: + +- `sonar.cpd.exclusions` gains `**/Configurations/*.cs` and `**/Modules/*.cs`. These are declarative EF entity configuration and Discord attribute-driven interaction wiring, where the repetition is the framework's required shape rather than logic. `**/Migrations/*.cs` stays. +- `sonar.coverage.exclusions` gains `**/RustPlusSocketSource.cs`, `**/RustPlusFcmPairingSource.cs`, `**/DiscordChatWebhookPoster.cs`, `**/DiscordClanFeedPoster.cs`, `**/ServerAutocompleteHandler.cs` — thin adapters over the RustPlusApi socket, the FCM listener and Discord.Net with no injectable seam. Together they account for 441 of the 1530 uncovered lines. + +Every other file stays in scope and gets real tests. + +## Testing + +New and extended test coverage, in rough priority order by uncovered lines: + +1. `EventLoopHostedService` — start subscribes eagerly, loops run, a throwing handler costs one event and not the subscription, cancellation ends cleanly, stop joins every loop. Covers the machinery behind five feature hosted services at once. +2. `ConnectionSupervisor` (153 uncovered, 38 uncovered conditions) — the largest testable hole. +3. `VendingStore` (127) and the vending feature: `VendingHostedService` (53), `VendingTrackService` (40), `VTrack`/`VUntrack` handlers. +4. `EventsHostedService` (64), `WorkspaceHostedService` (59), `MapHostedService` (42), `ChatHostedService` (31), `ServerInfoRefreshHostedService` (31). +5. `PairedDeviceCoordinator` — one test class replacing what would otherwise be three. +6. The command-handler tail: guard branches in `Chinook`, `Recycle`, `Upkeep`, `Item`, `Durability`, `Smelt`, `Craft`, `Decay`, `Research`, `Cctv`, `Events`, `Offline`, `Team`, `Wipe`, `SteamId`, `Vending`. +7. Small holes: `ClanChangeRenderer` (20 uncovered, 23 uncovered conditions), `MapSettingsStore`, `FcmRegistrationStore`, `WorkspaceStore`, `MapIcons`, `MapRenderStyle`, `ClanSnapshotSerializer`, `ChannelEditPacer`, the locators, and the one-line event/record types. + +Refactors are behaviour-preserving and guarded by the existing suite. Where a refactor has no existing guard (the pairing coordinator collapse, the hosted-service base), characterisation tests land before the refactor. + +## Verification + +Local, before the PR: + +``` +dtk dotnet test --collect:"XPlat Code Coverage;Format=opencover" +``` + +Aggregate the opencover reports and compute line and branch coverage; confirm the build is clean under `TreatWarningsAsErrors` with the full analyser set (NetAnalyzers, Roslynator, SonarAnalyzer, VS Threading) at `AnalysisLevel=latest-all`. The SonarAnalyzer package runs in-build, so S3776/S107/S1192 regressions surface as build errors locally rather than only in the Sonar report. + +Final confirmation comes from the Sonar analysis of the PR and, after merge, of `develop`. + +## Delivery + +One branch off `develop`, commits separated by concern (smells, each dedup cluster, coverage), one PR. + +## Risks + +- **The generic device coordinator** is the riskiest collapse. Mitigated by the confirmed structural diff (only the name prefix and the render call differ) and by characterisation tests written before the change. +- **The eager-subscribe change** alters start-up timing for five hosted services. It is the documented intent of `EventBusConsumption` and closes a real drop window, but it is a behaviour change and is called out in the PR description. +- **Coverage of 100% is not promised.** The exclusion list is deliberately narrow, so some genuinely awkward paths remain in scope. The commitment is >90% with an honest report of where it lands. +- **Duplication of exactly 0%** depends on Sonar's block detector; after the refactor a residual small block may remain. If one survives, it gets fixed or explicitly reported, not silently excluded beyond the two agreed exclusion patterns.

The simplest correct form is for `Loop` to eagerly capture the stream — but `Loops` is evaluated inside `StartAsync`, where the CTS token exists, so make `Loops` enumerate exactly once in `StartAsync` and materialise it to an array before starting any task. +- The handler-failure callback logs at `Error` with the message `"Handling {EventType} failed; skipping that event."` and `typeof(TEvent).Name`.

It now delegates to 8 single-condition rule methods (smelter count, has-conversions, input/output reference, output quantity, time, wood quantity, output probability), each independently testable and named after the rule it enforces. Adds GoodSmelter_hasNoErrors, the missing positive-case test proving a valid smelter produces no diagnostics; the 8 violation-case tests already existed and pass unchanged before and after the split.

} From 5f90ee40031511ddcae0fd928c24773ebbb82b3c Mon Sep 17 00:00:00 2001 From: = Date: Tue, 8 Sep 2026 04:22:09 +0200 Subject: [PATCH 18/34] refactor: collapse the device pairing coordinators onto a generic base Adds RustPlusBot.Features.Devices as the shared home for smart-device scaffolding. Switch and StorageMonitor pairing were structurally identical apart from the default-name prefix, the accepted-render call and the store interface; those are now the only things the subclasses supply. AlarmPairingCoordinator is left alone: it holds one DI scope across the whole accept (exists-check, add and set-message-id share a DbContext) and runs its race guard after reading the pending entry, where switches and storage monitors open a fresh scope per store touch and guard first. Folding it in would have changed alarm scope lifetimes silently.

ClanMessageShell now owns that and hands the loaded snapshot to each renderer's own body. The roster renderer carried a third copy of the same block, so it is folded in too rather than left as a residual duplicate. Longest identical run (blank/brace-only lines stripped), overview vs invites: 10 -> 7 (using directives only).

The periodic reachability sweep's device loop had never executed in any test: the existing sweep tests were satisfied by the connect-time prime, which publishes the same event types. No production code changed and no existing assertion touched. New test seams: fault/block hooks and a dispose counter on FakeConnection, a capturing logger provider (the supervisor's error paths are silent by design, so the log line is the only observable proof a path ran and was contained) and a FaultingEventBus.

Non_rig_monuments_and_non_chinook_markers_never_activate_a_rig parked its cargo ship on the only rig, so deleting the MarkerKind.Chinook guard just moved the single Activated(Small) from poll 2 to poll 1 and every assertion still held. The two rigs are now separated and the CH47-on-small-rig activation is published last as a barrier, so the guard is fenced by event ORDER: without it the sequence is [Small, Large] instead of [Large, Small]. Verified by mutation. Reconnect_backoff_stops_growing_at_the_configured_cap measured no delay at all — an uncapped 5/10/20/40/80ms sequence finishes well inside the 30s deadline. The fake now timestamps each Create, and the test asserts differentially that the 5th->6th gap did not double relative to the 4th->5th, which a uniformly slow runner cannot fake. Verified by mutation: 802ms then 1602ms.

VendingStore, VendingTrackService, VendingNotificationRelay, VendingEmbedRenderer and both grid-tracking command handlers reach 100% line and branch coverage; VendingHostedService reaches 95.1%. Every guard-type test was checked by mutation: the production guard it exists to protect was removed or inverted locally and the test confirmed to fail. The two lines left uncovered in VendingHostedService are unreachable as the code stands: StopAsync's OperationCanceledException catch cannot fire because each consumer loop already swallows cancellation, and the connection-status loop's handler-failure callback cannot fire because HandleConnectionStatusAsync has no failure mode for any event the bus can deliver. No production code changed.

A future DbSet or a navigation targeting the base would have flipped EF to table-per-hierarchy and collapsed SmartSwitches and SmartStorageMonitors into one discriminated table. Ignore() states the intent and makes EF enforce it, with a test pinning that the base is absent from the model and explicitly ignored, and that the two device types keep separate tables and no base type.
