Daraus folgen fünf konkrete +Einschränkungen, die den Betrieb einer Microservice-Flotte behindern. + +### P1 — `pluginName` ist dreifach überladen + +`pluginName` ist gleichzeitig Connection-Name, Request-Queue-Name und Callback-Queue-Prefix. +Ein Client kann strukturell nur den Service ansprechen, der denselben Namen trägt. Ein +Paper-Plugin, das `surf-factions` und `surf-punish` aufruft, benötigt zwei vollständige +`ClientRabbitMQApi`-Instanzen: zwei TCP-Verbindungen, zwei Publisher-Pools, zwei +Callback-Queues, zwei Consumer-Threadpools. Eine Zieladressierung existiert nicht. + +### P2 — Kein Fire-and-Forget, kein Broadcast + +Die einzige Sende-API ist `sendRequest(request, responseClass)` und wartet zwingend auf eine +Antwort. Jedes Event ist ein synchroner Round-Trip mit 60 s Timeout. `RabbitConsumer.declareExchange()` +und `RabbitConsumer.bindQueue()` existieren, werden aber nirgends aufgerufen — toter Code. + +### P3 — Kein Service-zu-Service-Aufruf + +`ServerRabbitMQApi` besitzt kein `sendRequest`. Ein Microservice kann keinen anderen +Microservice aufrufen. + +### P4 — Der Client deklariert fremde Queues + +`AbstractRabbitMQConnectionImpl.connect()` läuft auf beiden Seiten identisch und deklariert +`queue = api.pluginName` als durable. Der Client deklariert damit die Queue des Servers, ohne +sie je zu konsumieren. Ändert der Service seine Queue-Argumente (DLX, Quorum, TTL), erhält der +Client `PRECONDITION_FAILED (406)`. Da Request- und Callback-Queue denselben Channel des +`mainConsumer` teilen, reißt der Channel-Fehler auch den RPC-Rückkanal mit. + +### P5 — Nachrichtenverlust ohne Spur + +Bei Deserialisierungsfehler, fehlendem Handler, Handler-Exception, Timeout und fehlender +`correlationId` folgt jeweils `ack.nack(requeue = false)`. Ohne Dead-Letter-Exchange ist die +Nachricht anschließend verloren. Kein Audit, kein Replay, keine Diagnose. + +### Weitere Befunde + +- `mandatory = false` bei allen Publishes: nicht routbare Nachrichten verschwinden still, + der Aufrufer läuft in einen 60-Sekunden-Timeout statt sofort zu scheitern. +- Classic Queues statt Quorum Queues. +- `ClientRabbitMQConnectionImpl.kt:312` setzt `expiration` pauschal auf jede ausgehende + Nachricht.

Synchronous service-to-service RPC is documented as an anti-pattern. - Add SHARED and BROADCAST subscription modes.

Each target service gets its own circuit breaker from `surf-circuitbreaker`. + +**Tech Stack:** Kotlin (JVM toolchain 25), amqp-client 5.34.0, `surf-circuitbreaker`, JUnit 5, Testcontainers. + +## Global Constraints + +- All Global Constraints from Plans 2 and 3 still apply. +- Retry queues, verbatim from the spec: `surf.retry.10s` (TTL 10 000 ms), + `surf.retry.60s` (60 000 ms), `surf.retry.300s` (300 000 ms). All dead-letter to `surf.rpc`. +- **Never set `x-dead-letter-routing-key` on a retry queue.** RabbitMQ then preserves the + original routing key, which is the entire reason three shared queues can serve every service. +- Retry ladder, verbatim from the spec: `n = 0` → `10s`, `n = 1` → `60s`, `n = 2` → `300s`, + `n = 3` → dead-letter queue.

From 56f6f202b088a2ef786591420396459fe7bf3450 Mon Sep 17 00:00:00 2001 From: Ammo Date: Wed, 29 Jul 2026 12:38:06 +0200 Subject: [PATCH 05/84] docs: add chunk-series bugfix and failure-during-processing tests Reviewing what happens when a microservice dies while sending its reply surfaced a real defect: chunk assembly is keyed by correlationId alone, so a redelivered message's chunks get merged with the leftovers of the aborted attempt. Size checks miss it because both attempts serialise to the same length. Latent today because failed messages are discarded - the retry ladder in this plan would have made redelivery routine. Adds Task 10 (series id in the chunk header) and Task 11 (seven failure scenarios: death before, during and after the handler, midway through a chunked reply, with the last instance gone, and broker loss while publishing or awaiting).

Each tier is a `fanout` exchange plus a queue whose dead-letter exchange is `""` (the default exchange): the republish carries **the origin queue's name as routing key**, the fanout ignores it for insertion, and on TTL expiry the default exchange routes the message straight back into exactly the queue it came from — service queues and shared event queues alike. After three retries the message goes to the service's dead-letter queue. Unroutable publishes are caught by a `ReturnListener` that fails the caller immediately *and* republishes the returned body into the `surf.unroutable` audit queue.

Six modules become two; no behaviour changes. surf-rabbitmq-core keeps the plain "core" gradle plugin rather than "standalone": the standalone convention plugin bundles surf-api's dependencies into the shaded jar, which would bloat every Paper/Velocity consumer and risk version conflicts. StandaloneLifecycleHookImpl (moved in from the old surf-rabbitmq-server) instead gets a compileOnly dependency on surf-api-standalone: it satisfies the compiler without shipping the dependency to non-standalone consumers, and genuine standalone processes (e.g. surf-rabbitmq-test-server) already apply the standalone plugin themselves and supply the real dependency at runtime. ---

Ammo Date: Wed, 29 Jul 2026 14:20:30 +0200 Subject: [PATCH 20/84] feat(api): replace client and server APIs with a single SurfRabbitApi Capability now follows from which register methods a process calls rather than from which API class it constructed. One instance can address any number of services over one connection. - SurfRabbitApi/SurfRabbitApiBuilder replace ClientRabbitMQApi, ServerRabbitMQApi and the RabbitMQApi base class. - rpcService and connection are lazy: constructing a SurfRabbitApi (e.g. for tests) no longer requires a broker-facing implementation to already be registered via ServiceLoader. - ClientRabbitRpcService/ServerRabbitRpcService merge into one RabbitRpcService interface; the merged RabbitRpcServiceImpl (core) replaces ClientRpcServiceImpl/ServerRabbitRpcServiceImpl. - RabbitRpcServiceDescriptor.createInstance and RabbitRpcCall now carry a RabbitTarget; the KSP codegen threads it through the generated constructor and createInstance call. - GlobalRabbitMQConfig's config cache is keyed by (path, fileName) instead of a single JVM-wide instance, so configFileName() and multiple SurfRabbitApi instances in one JVM (a Paper server full of plugins) no longer silently share whichever file loaded first. - SurfRabbitApiAlreadyFrozenException/SurfRabbitApiNotFrozenException now extend IllegalStateException directly (state precondition, not a wire-protocol error). surf-rabbitmq-core does not compile yet - the connection fusion is Task 7. All failures there are exactly the deleted RabbitMQApi surface. --- surf-rabbitmq-api/api/surf-rabbitmq-api.api | 57 ++---- surf-rabbitmq-api/build.gradle.kts | 9 + .../surf/rabbitmq/api/ClientRabbitMQApi.kt | 123 ------------ .../dev/slne/surf/rabbitmq/api/RabbitMQApi.kt | 141 ------------- .../surf/rabbitmq/api/ServerRabbitMQApi.kt | 164 --------------- .../slne/surf/rabbitmq/api/SurfRabbitApi.kt | 174 ++++++++++++++++ .../surf/rabbitmq/api/SurfRabbitApiBuilder.kt | 100 +++++++++ .../connection/ClientRabbitMQConnection.kt | 17 -- .../api/connection/RabbitMQConnection.kt | 17 +- .../connection/RabbitMQConnectionFactory.kt | 4 +- .../connection/ServerRabbitMQConnection.kt | 5 - .../slne/surf/rabbitmq/api/exception/api.kt | 9 +- .../surf/rabbitmq/api/exception/protocol.kt | 9 +- .../internal/config/GlobalRabbitMQConfig.kt | 30 ++- .../api/rpc/ClientRabbitRpcService.kt | 10 - .../surf/rabbitmq/api/rpc/RabbitRpcCall.kt | 6 +- .../surf/rabbitmq/api/rpc/RabbitRpcService.kt | 21 +- .../api/rpc/RabbitRpcServiceFactory.kt | 6 +- .../api/rpc/ServerRabbitRpcService.kt | 10 - .../descriptor/RabbitRpcServiceDescriptor.kt | 7 +- .../rabbitmq/api/SurfRabbitApiBuilderTest.kt | 95 +++++++++ .../client/rpc/ClientRpcServiceFactory.kt | 14 -- .../client/rpc/ClientRpcServiceImpl.kt | 90 --------- .../common/rpc/CommonRabbitRpcServiceImpl.kt | 43 ---- .../rpc/RabbitRpcServiceFactoryImpl.kt | 13 ++ .../surf/rabbitmq/rpc/RabbitRpcServiceImpl.kt | 189 ++++++++++++++++++ .../rpc/ServerRabbitRpcServiceFactory.kt | 14 -- .../rpc/ServerRabbitRpcServiceImpl.kt | 67 ------- .../dev/slne/surf/rabbitmq/processor/Names.kt | 3 +- .../rpc/codegen/RpcClientImplCodegen.kt | 13 +- .../rpc/codegen/RpcDescriptorCodegen.kt | 3 +- 31 files changed, 689 insertions(+), 774 deletions(-) delete mode 100644 surf-rabbitmq-api/src/main/kotlin/dev/slne/surf/rabbitmq/api/ClientRabbitMQApi.kt delete mode 100644 surf-rabbitmq-api/src/main/kotlin/dev/slne/surf/rabbitmq/api/RabbitMQApi.kt delete mode 100644 surf-rabbitmq-api/src/main/kotlin/dev/slne/surf/rabbitmq/api/ServerRabbitMQApi.kt create mode 100644 surf-rabbitmq-api/src/main/kotlin/dev/slne/surf/rabbitmq/api/SurfRabbitApi.kt create mode 100644 surf-rabbitmq-api/src/main/kotlin/dev/slne/surf/rabbitmq/api/SurfRabbitApiBuilder.kt delete mode 100644 surf-rabbitmq-api/src/main/kotlin/dev/slne/surf/rabbitmq/api/connection/ClientRabbitMQConnection.kt delete mode 100644 surf-rabbitmq-api/src/main/kotlin/dev/slne/surf/rabbitmq/api/connection/ServerRabbitMQConnection.kt delete mode 100644 surf-rabbitmq-api/src/main/kotlin/dev/slne/surf/rabbitmq/api/rpc/ClientRabbitRpcService.kt delete mode 100644 surf-rabbitmq-api/src/main/kotlin/dev/slne/surf/rabbitmq/api/rpc/ServerRabbitRpcService.kt create mode 100644 surf-rabbitmq-api/src/test/kotlin/dev/slne/surf/rabbitmq/api/SurfRabbitApiBuilderTest.kt delete mode 100644 surf-rabbitmq-core/src/main/kotlin/dev/slne/surf/rabbitmq/client/rpc/ClientRpcServiceFactory.kt delete mode 100644 surf-rabbitmq-core/src/main/kotlin/dev/slne/surf/rabbitmq/client/rpc/ClientRpcServiceImpl.kt delete mode 100644 surf-rabbitmq-core/src/main/kotlin/dev/slne/surf/rabbitmq/common/rpc/CommonRabbitRpcServiceImpl.kt create mode 100644 surf-rabbitmq-core/src/main/kotlin/dev/slne/surf/rabbitmq/rpc/RabbitRpcServiceFactoryImpl.kt create mode 100644 surf-rabbitmq-core/src/main/kotlin/dev/slne/surf/rabbitmq/rpc/RabbitRpcServiceImpl.kt delete mode 100644 surf-rabbitmq-core/src/main/kotlin/dev/slne/surf/rabbitmq/rpc/ServerRabbitRpcServiceFactory.kt delete mode 100644 surf-rabbitmq-core/src/main/kotlin/dev/slne/surf/rabbitmq/rpc/ServerRabbitRpcServiceImpl.kt diff --git a/surf-rabbitmq-api/api/surf-rabbitmq-api.api b/surf-rabbitmq-api/api/surf-rabbitmq-api.api index 846695b..be0b034 100644 --- a/surf-rabbitmq-api/api/surf-rabbitmq-api.api +++ b/surf-rabbitmq-api/api/surf-rabbitmq-api.api @@ -1,59 +1,38 @@ -public final class dev/slne/surf/rabbitmq/api/ClientRabbitMQApi : dev/slne/surf/rabbitmq/api/RabbitMQApi { - public static final field Companion Ldev/slne/surf/rabbitmq/api/ClientRabbitMQApi$Companion;

Reply, service and instance queues each get their own consumer/channel, so a failed declare no longer takes down the RPC reply path. The reply queue now has a stable name (surf.reply.) instead of a renamed-on-recovery callback queue, so recovery signaling no longer needs the rename-tracking machinery: RabbitClient.newCallbackQueueName(), setRecoveredQueueNameSupplier and RabbitQueueNames are all gone. A process consumes its service and instance queues only if it registered a handler or an RPC service. registerService() never touches the connection directly, so RabbitRpcService gained hasRegisteredServices() for the connection to check at connect time; RabbitListenerHandlerManager separately tracks explicit registerRequestHandler() calls so its own always-present internal RPC dispatcher entry doesn't make hasHandlers() report true for a process that registered nothing itself. --- .../surf/rabbitmq/api/rpc/RabbitRpcService.kt | 9 + .../ClientRabbitMQConnectionFactory.kt | 13 -

KotlinSerializerCache/KotlinSerializerNameCache move into shared.serialization. - The reflection invoker (RabbitListenerHandlerTemplate, RabbitListenerMethodHandleProvider) moves into shared.dispatch, renamed to HandlerTemplate/HandlerMethodHandleProvider since the names must not say "Rabbit". HandlerTemplate is now public since it implements RabbitListenerHandler from a different package. The Velocity reflection proxies (JavaPluginLoaderProxy, SerializedPluginDescriptionProxy) are deliberately NOT moved into platform.* in this commit: that move crosses from surf-rabbitmq-velocity into surf-rabbitmq-core and touches classloader-sensitive reflection plumbing with no Velocity runtime available here to verify against.

Der harte Schnitt trifft ausschließlich Events. + +## Öffentliche API + +### Aufbau + +```kotlin +val bus = SurfEventBus.builder("surf-factions", dataPath) + .provider(Provider.RABBIT) // optional; Default kommt aus der Konfiguration + .instanceName("lobby-3") // optional; stabile Instanz-Identität + .serializers(FactionsSerializers) + .build() + +bus.registerListener(FactionCacheListener) +bus.freezeAndConnect() +``` + +Der Builder übernimmt die Identitätsoptionen des heutigen `SurfRabbitApiBuilder` +(`serviceName`, `dataPath`, `instanceName`, `serializers`) und gibt sie an den gewählten +Transport weiter. `instanceName` bleibt Voraussetzung für `InstanceTarget` auf der +rabbit-spezifischen API. + +Der Bus besitzt den Lebenszyklus des Transports: ein `freeze`, ein `connect`, eine Verbindung +pro Prozess. Die transportspezifische API desselben Prozesses — und damit derselben Verbindung +— ist über einen typisierten Zugang erreichbar: + +```kotlin +val rabbit = bus.transport() // scheitert laut, wenn Provider != RABBIT +val factions = rabbit.rpc() + +val redis = bus.transport() // scheitert laut, wenn Provider != REDIS +val online = redis.createSyncSet("online-players") +``` + +`transport()` ist die **einzige** Stelle, an der der Transport im Code sichtbar wird. Sie +ist absichtlich unbequem und typgebunden: wer sie benutzt, verlässt die Portabilität, und das +soll man am Aufrufort sehen. + +### Events + +```kotlin +@Serializable +@BusEvent("faction.disbanded") +class FactionDisbandedEvent(val factionId: UUID) : SurfBusEvent() + +bus.publish(FactionDisbandedEvent(id)) +``` + +Das Topic steht am Typ, nicht am Aufrufort — ein Publisher kann dasselbe Event nicht unter +zwei Schlüsseln versenden. Topics sind punktgetrennt und wildcardfrei. + +### Abonnements + +```kotlin +object FactionCacheListener { + + // Default: genau eine Instanz verarbeitet, durable + @SurfSubscribe + suspend fun onDisbanded(event: FactionDisbandedEvent) { + database.deleteFaction(event.factionId) + } + + // Jede Instanz verarbeitet, ephemer + @SurfSubscribe(mode = SubscriptionMode.BROADCAST) + suspend fun onReload(event: ConfigReloadedEvent) { + config.reload() + } + + // Weiteres Muster als das Topic des Events selbst + @SurfSubscribe(topic = "faction.#", mode = SubscriptionMode.BROADCAST) + suspend fun onAnyFactionEvent(event: FactionEvent) { + cache.invalidateAll() + } +} +``` + +`@SurfSubscribe(topic, mode, retry, includeSelf)`. Semantik von `topic`, `mode` und `retry` +übernimmt unverändert das heutige `@RabbitSubscribe` — `*` trifft genau ein Segment, `#` null +oder mehr, `SHARED` ist Default, weil der Fehlerfall eines versehentlichen `BROADCAST` +(n-fache Ausführung mit Seiteneffekt) teurer ist als der umgekehrte. + +## Capability-Modell + +Ein Transport deklariert, was er leisten kann. Der Bus prüft beim `freeze()` jedes +Abonnement gegen diese Deklaration. + +| Capability | RabbitMQ | Redis Pub/Sub | +|---|---|---| +| `BROADCAST` | ja | ja | +| `SHARED` | ja — durable Quorum-Queue pro Service | **nein** | +| `RETRY` | ja — 10 s/60 s/300 s | **nein** | +| `DEAD_LETTER` | ja — `surf.dlq.` | **nein** | + +Zwei verschiedene Reaktionen, nach Schadensart getrennt: + +**Fehlende `SHARED`-Fähigkeit ist ein Startfehler.** Der Modus entscheidet, *wie oft* ein +Handler läuft. Ein stillschweigend nach `BROADCAST` degradierter Handler würde auf acht +Instanzen achtmal in die Datenbank schreiben; ein stillschweigend verworfenes Event verschwindet +ohne Spur. Beides darf nicht passieren: + +``` +IllegalStateException: + Handler StatsListener#onBanned uses mode SHARED, + but provider REDIS supports only BROADCAST. + SHARED requires a durable per-service queue. + -> use provider RABBIT, or change the + handler to BROADCAST if duplicate + execution on every instance is safe. +``` + +**Fehlendes `RETRY` ist eine Startwarnung.** `retry = true` ist der Default und stünde +deshalb an praktisch jedem Handler; ein Fehler wäre unbrauchbar. Der Schaden ist außerdem +kleiner: es geht nicht um die Anzahl der Ausführungen, sondern nur darum, was nach einem +Handler-Fehler passiert. Der Bus nennt beim Start jeden betroffenen Handler einmal namentlich: + +``` +WARNING: provider REDIS does not support RETRY or DEAD_LETTER. + A failing handler is logged and the event is gone. + Affected handlers: StatsListener#onJoin, TabListener#onQuit +``` + +Die Capability-Deklaration ist der Angelpunkt dieses Entwurfs: sie macht die +Zustellgarantie zu einer geprüften Eigenschaft statt zu einer Zeile Dokumentation. Die +Topologie-Spec hat eine gemeinsame `sendRequest()`-Abstraktion abgelehnt, weil sie „am +Aufrufort verbergen würde, welche Garantie gilt". Genau dagegen steht das Capability-Modell. + +## Wire-Format und Routing + +Der Envelope ist logisch gleich, seine Kodierung gehört dem Transport: + +| Feld | Zweck | +|---|---| +| `topic` | Routing-Schlüssel, aus `@BusEvent` | +| `type` | FQCN der Event-Klasse, für die Deserialisierung beim Empfänger | +| `originInstanceId` | wer publiziert hat — Grundlage der Selbstzustellungs-Filterung | +| `publishedAtEpochMs` | Diagnose, ersetzt `RedisEvent.timestamp` | +| Payload | das serialisierte Event | + +### RabbitMQ + +Unverändert die Topologie aus dem Redesign: `surf.events` als `topic`-Exchange, Routing-Key = +Topic, `surf.events.shared.` (quorum, durable) für `SHARED`, +`surf.events.instance.` (ephemer) für `BROADCAST`, Retry-Leiter und +`surf.dlq.` dahinter. Kodierung CBOR. Das Muster-Matching macht der Broker. + +### Redis Pub/Sub + +Ein Event wird auf **einen** Kanal publiziert: `surf.eventbus.`. Abonniert wird +abhängig vom Muster: + +| Abonnement | Redis-Operation | Muster-Prüfung | +|---|---|---| +| wildcardfrei (`faction.disbanded`) | `SUBSCRIBE surf.eventbus.faction.disbanded` | keine nötig | +| mit Wildcard (`faction.#`) | `PSUBSCRIBE surf.eventbus.*` | lokal, mit AMQP-Semantik | + +Der Umweg über lokale Prüfung bei Wildcards ist unvermeidbar: Redis-Glob und AMQP-Topics +haben unterschiedliche Semantik — Redis' `*` überquert Punkte, AMQPs `*` trifft genau ein +Segment. Nur lokale Prüfung ergibt auf beiden Transports **dasselbe** Ergebnis, und identisches +Verhalten ist der Sinn der Übung. Der häufige wildcardfreie Fall zahlt diesen Preis nicht: er +abonniert seinen exakten Kanal und der Broker filtert. + +Beide Transports benutzen dieselbe Matcher-Implementierung (`EventTopics` aus +`surf-eventbus-api`), die schon heute die Broker-Semantik nachbildet und unit-getestet ist. + +### Provider-Mischbetrieb + +**Gibt es nicht.** Zwei Provider in einer Flotte bedeuten zwei disjunkte Event-Universen — ein +Event aus dem Redis-Teil erreicht den Rabbit-Teil nie. Der Provider ist deshalb eine +Fleet-Entscheidung und gehört in die globale Konfiguration, nicht in die Plugin-Konfiguration. +Ein Prozess, dessen Provider von der globalen Vorgabe abweicht, protokolliert das beim Start +auf `WARNING` mit beiden Werten. + +## Selbstzustellung + +`@SurfSubscribe(includeSelf = false)` ist der Default: ein Handler sieht keine Events, die +sein eigener Prozess publiziert hat. Begründung: alle rund zwanzig bestehenden +`@OnRedisEvent`-Handler beginnen mit genau dieser Zeile — + +```kotlin +if (event.originatesFromThisClient()) return +``` + +— und die häufigste Ursache einer Rückkopplungsschleife ist, sie zu vergessen. Der Default +kodifiziert die bestehende Praxis. `SurfBusEvent.originInstanceId` bleibt lesbar, wer +Selbstzustellung will, setzt `includeSelf = true`. + +**`includeSelf` gilt nur für `BROADCAST`.** In Kombination mit `SHARED` wird es bei der +Registrierung abgelehnt. Grund: eine `SHARED`-Nachricht wurde aus einer geteilten Queue +entnommen. Sie lokal zu verwerfen hieße, sie zu quittieren, ohne sie zu verarbeiten — sie ist +dann für die gesamte Flotte verloren, nicht bloß für diese Instanz. + +## Dispatch + +Ein Weg für beide Transports, in `surf-eventbus-common`: + +- **Hidden-Class-Invoker** über `InvokerFactory` aus `surf-api-core` — der Weg, den surf-redis + heute für Events geht und surf-rabbitmq für Request-Handler. surf-rabbitmqs + `EventDispatcher` dispatcht Events heute per `Method.invoke`; er wird auf den Invoker-Pfad + gezogen. +- **Typhierarchie-bewusst**, wie heute bei RabbitMQ: ein Handler für `FactionEvent` erhält + auch `FactionDisbandedEvent`. surf-redis' Beschränkung auf exakte Typen fällt weg — sie + macht `@SurfSubscribe(topic = "faction.#")` mit einem Basistyp-Parameter erst benutzbar. +- **Alle passenden Abonnements laufen.** Ein Handler auf `faction.disbanded` und einer auf + `faction.#` feuern beide. +- **Ein scheiternder Handler stoppt seine Nachbarn nicht.** Der erste Fehler wird nach dem + Durchlauf aller Handler geworfen, damit der Transport über Retry entscheiden kann. +- **Unbekannter `type`** — kein Handler im Prozess registriert die Klasse: einmal warnen, + quittieren, verwerfen. Nicht requeuen; eine durable `SHARED`-Queue würde die Nachricht sonst + endlos erneut zustellen. Die Warnung ist die einzige Spur einer veralteten Binding-Leiche und + bleibt deshalb laut. + +Validiert wird bei der Registrierung, nicht bei der Zustellung: Parameterzahl, Parametertyp, +Muster-Syntax, Modus/Capability, `includeSelf`/Modus-Kombination. Ein fehlerhaftes Muster +bindet auf dem Broker beschwerdefrei und trifft dann nichts — das einzige Symptom wäre ein +Event, das nie ankommt. + +## Lebenszyklus + +Ein einziges Modell für beide Transports, `suspend`, in `surf-eventbus-common` beschrieben: + +``` +build() → registerListener()* → freeze() → connect() → … → disconnect() +``` + +`freeze()` prüft Capabilities und schließt die Registrierung — Handler müssen bekannt sein, +bevor der Consumer startet, sonst trifft eine Nachricht einen halb registrierten Handler. + +surf-redis' blockierendes, Reactor-basiertes `connect()` wird auf `suspend` umgestellt. Das +betrifft die redis-spezifische API sichtbar (`RedisApi.connect()` ist heute `@Blocking`) und +ist Teil des harten Schnitts. Die Reactor-Interna (`Initializable.init(): Mono`) bleiben +intern erhalten; nur die Naht nach außen wird `suspend`. + +**Redis-Sync-Strukturen bleiben an ihre Vorbedingung gebunden:** vor `freeze()` erstellen. +Diese Falle (die READMEs widmen ihr einen eigenen Abschnitt) bleibt bestehen, weil sie in der +Natur der Sache liegt; sie wird nur einmal statt zweimal dokumentiert. + +## Konfiguration + +Das vierstufige Modell aus surf-rabbitmq wird für alles verbindlich und zieht nach +`surf-eventbus-common`: + +``` +env > Plugin-YAML > globale YAML > Default +``` + +Neu: + +| Schlüssel | Env | Default | +|---|---|---| +| `eventbus.provider` | `SURF_EVENTBUS_PROVIDER` | der einzige auf dem Classpath gefundene Transport | + +Liegen beide Transport-Module auf dem Classpath und ist nichts konfiguriert, scheitert der +Start und nennt beide gefundenen Provider. Raten wäre hier falsch: die Wahl entscheidet über +die Zustellgarantie. + +Die Redis-Verbindungsdaten behalten `RedisCredentialsProvider`, die RabbitMQ-Verbindungsdaten +ihre `SURF_RABBITMQ_*`-Variablen; beide unverändert. + +## Was transportgebunden bleibt + +Bewusst **nicht** vereinheitlicht, mit Begründung: + +| Bereich | Bleibt bei | Grund | +|---|---|---| +| RPC (`rpc()`, `@RpcService`, KSP-Proxies) | RabbitMQ | Zustellung an genau eine Instanz, garantiert und persistent.

Eine Relocation-Basis: + `dev.slne.surf.eventbus.shaded.io.netty`. Der `META-INF/native`-Mangling-Block existiert + danach einmal. +- **Ein Plattform-Plugin pro Plattform** statt zwei. Es enthält beide Transports geshadet. + Der Preis ist ein größeres Jar; der Gegenwert ist ein Plugin statt zwei auf jedem Server und + eine Netty-Kopie statt zwei.

Plan 2 builds the broker-free bus core, proven against an in-memory transport. Plan 3 implements both transports and asserts identical behaviour against real brokers.

Structure and naming: - every package moves under dev.slne.surf.eventbus, artifacts follow - modules nest per area, plus surf-eventbus-api / -core aggregates for consumers that want one coordinate - surf-circuitbreaker stops being its own artifact and joins surf-eventbus-common - all environment variables become SURF_EVENTBUS_*, and a leftover old name is a start failure rather than a silent localhost fallback Division of labour instead of provider choice: - both transports run at once, enabled at the builder; eventbus.provider and SURF_EVENTBUS_PROVIDER are gone - events and queries are Redis, RPC is RabbitMQ, and no capability exists twice - SubscriptionMode disappears: Redis Pub/Sub can only broadcast, so a modeled choice would be a lie - fire-and-forget becomes a marker on an RPC method, which retires the untyped packet API - Redis request/response survives as a typed @QueryService: null abstains, a timeout returns null, and a throwing handler is audited rather than answered Audit instead of dead-letter queues: - surf.dlx, surf.dlq.* and surf.unroutable give way to three database tables written by a microservice in this repository - six loss paths report over fire-and-forget; the write never fails hard - reports are never audited themselves, and the audit service never reports to itself Also corrects four claims against the actual state of surf-redis 1.10.1, which is 81 commits past the version the first draft was written against: it does have environment variables, it does have tests, its events already have an opt-in binary codec channel worth keeping, and IoUringRedissonPatcher has been replaced by TransportInfo.

Ein RPC-Aufruf sagt „genau +einer tut das"; über Pub/Sub wäre das eine Lüge, weil jeder zuhörende Prozess den Handler +ausführt. Ein Query sagt „wer zuständig ist, antwortet" — und macht die Abstinenz zur +Pflichtübung im Rückgabetyp, damit die Mehrfachausführung sichtbar bleibt statt versteckt. + +Deshalb bleibt `rpc()` rabbit-gebunden. Echte RPC-Parität über Redis wäre nur über **Redis +Streams** machbar: Consumer-Groups, `XREADGROUP`, `XACK`, `XAUTOCLAIM`, +Pending-Entry-Verwaltung und Trimming — ein größeres Subsystem als der ganze restliche Bus. Die +Aufgabenteilung nimmt ihm den Anlass: wer RPC braucht, schaltet `withRabbit()` frei. + +Die Tür bleibt offen: eine Streams-Implementierung könnte später durable Events und RPC über +Redis nachliefern, ohne die API zu ändern. + +### Wann `rpc`, wann `query` + +| Situation | Verb | +|---|---| +| Ich kenne den Dienst, der es tun soll | `rpc()` | +| Ich kenne die Instanz, die es tun soll | `rpc(InstanceTarget(id))` | +| Es muss verlässlich passieren, auch wenn gerade niemand läuft | `rpc()` auf `@FireAndForget` | +| Ich weiß nicht, wer zuständig ist, und will eine Antwort | `query()` | +| Alle sollen es erfahren, niemand muss antworten | `publish(event)` | + +### Wofür `InstanceTarget` da ist + +`InstanceTarget` hat heute **keinen Consumer** — es ist Teil der 2.0-Fläche, die noch nicht in +Benutzung ist. Sein Anwendungsfall existiert aber produktiv, nur als Broadcast gebaut: surf-cores +`ExecuteCommandServerRequest` („führe `/x` auf lobby-03 aus") und `ShutdownServerRequest` +(„fahre lobby-03 runter") nennen beide einen Zielserver und werden an die ganze Flotte gesendet, +wo jeder Prozess prüft, ob er gemeint ist. + +Das ist der Fall: **eine Operation auf einem namentlich bekannten Server.** Nicht lobby-01, das +lobby-03 etwas erzählen will — der Aufrufer ist ein Proxy, ein Adminwerkzeug oder ein +Microservice, und die Adresse steht bereits im Befehl. Für lobby-zu-lobby-Verkehr ist es das +falsche Werkzeug; wer dort landet, sollte den Zustand eher in eine Redis-Struktur legen. + +Warum nicht einfach ein Query, wo das doch jetzt existiert: + +| | `query()` | `rpc(InstanceTarget(id))` | +|---|---|---| +| Nachrichten | ein Publish, jeder Prozess deserialisiert und verwirft | ein Publish, ein Empfänger | +| Ziel ist offline | `null`, nach dem vollen Timeout | sofortiger `UNROUTABLE`-Fehler mit Namen | +| Ziel gibt es nicht (Tippfehler) | `null`, nicht von „offline" zu unterscheiden | sofortiger Fehler | +| Aufwand | wächst mit der Flottengröße | konstant | + +Der entscheidende Unterschied ist die zweite Zeile. „Fahre lobby-03 runter" muss unterscheiden +können zwischen „getan", „lobby-03 ist nicht verbunden" und „der Handler ist kaputt". Ein Query +liefert für die letzten beiden dasselbe `null`, und zwar erst nach fünf Sekunden. Für einen +Operatorbefehl ist das die falsche Antwort. + +Der Preis ist gering: eine ephemere Queue pro Prozess, die bereits deklariert wird, und eine +Variante an einem `sealed interface`. Fällt die Begründung weg, fällt mit `InstanceTarget` auch +`surf.instance.` aus der Topologie — dann bliebe `instanceName` nur noch für +`originInstanceId` und die Reply-Queue nötig. ## Build, Shading, Koordinaten - **Gruppe** für alle Module: `dev.slne.surf.eventbus`. **Version** 2.0.0. - **`rootProject.name`** wird `surf-eventbus`.

From 87dd95e2eb276be84e6fca627c667376ce144dac Mon Sep 17 00:00:00 2001 From: Ammo Date: Fri, 31 Jul 2026 15:02:02 +0200 Subject: [PATCH 46/84] docs: replan surf-eventbus in four stages against the new spec MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replaces the four plans written against the previous draft; every stage they described has either changed shape or moved. - 1-fundament: rename, nest the modules, absorb surf-circuitbreaker and the shared foundation into surf-eventbus-common, pull surf-redis 1.10.1 in, and converge Netty. No behaviour changes. - 2-bus-api-und-core: the event types, topic matcher, registry, envelope, dispatcher and lifecycle, tested against fake transports so none of it needs a broker. - 3-transports-und-vertraege: the Redis event and query transports, @FireAndForget, the KSP work for both contract kinds, and the three deletions that follow their replacements. - 4-audit-plattform-doku: the audit path, the microservice that writes it, the aggregates, one plugin per platform, the container suites and the rollout note. Ordering is load-bearing: every deletion comes after its replacement, so no stage ends unbuildable. Three guard tests exist because their failures are otherwise silent — a half-finished package rename still compiles, a Netty relocation base containing "lib" only breaks on a real server, and a forgotten api() line in an aggregate only surfaces in a consumer's build.

Moved and renamed by hand in the same tasks. +- A `META-INF/services/com.google.devtools.ksp.processing.SymbolProcessorProvider` resource file + under `surf-eventbus-ksp` referenced the old FQCN and needed a manual rename in Task 2. +- `RelocationBaseTest`'s second assertion assumed the checkout directory is literally named + `surf-eventbus`; this checkout's directory is still `surf-rabbitmq` (the plan does not rename + the working directory). Rewrote the exclusion to compare the resolved path against the root + `build.gradle.kts` instead of comparing directory names, preserving the guard's intent. +- `surf-eventbus-common` needed a `compileOnly("com.velocitypowered:velocity-api:3.5.0-SNAPSHOT")` + dependency (the coordinate the `dev.slne.surf.api.gradle.velocity` convention plugin injects) + because the Velocity reflection proxies moved there but the module itself doesn't apply that + plugin.

1c7200f3e01dd7a666e55a9d85d0bf7903db9904 Mon Sep 17 00:00:00 2001 From: Ammo Date: Fri, 31 Jul 2026 17:32:57 +0200 Subject: [PATCH 61/84] feat: add the Redis event transport with two channel families Wildcard-free subscriptions let the broker filter; wildcard subscriptions match locally because Redis glob crosses dots. BinaryFrame keeps the envelope readable in front of a codec payload. RedisTransportLocator now looks the transports up via ServiceLoader (requiredService), matching RedisComponentProvider's own pattern, instead of throwing a forward-reference error. RedisTransportProviderImpl.query() still throws until Plan 3 Task 7 adds the Redis query transport. Docker is reachable on this machine, so RedisEventTransportTest ran for real (7/7 passed) instead of being skipped.

2026 17:39:55 +0200 Subject: [PATCH 62/84] feat!: remove RedisEvent, @OnRedisEvent and RedisEventBus MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Their replacement is SurfEventBus over RedisEventTransport. BusEventCodecs (bus-core) already discovers a binary codec from an event's companion object with no stable eventId, no collision bookkeeping, and no packet- size estimation, so EventCodecRegistry/EventCodecRegistration/ CustomEventPacketCodec are deleted rather than rekeyed onto the event class — nothing would have called the rekeyed version. The JMH benchmark now measures EventEnvelope + BinaryFrame + BusEventCodec directly instead of the old packet codec.

The test-paper smoke-test instance's broadcast-event demo used the deleted API and is removed rather than ported; a Redis-based replacement arrives once the platform module wires up SurfEventBus. RetryQueueTest's shared-tier-for-events case is dropped: events no longer touch the RabbitMQ retry ladder.

RabbitRpcServiceImpl.call() branches on the callable's fireAndForget flag and publishes via connection.send() instead of waiting for a reply; the server-side fire-and-forget path already existed in RabbitListenerHandlerManager for the untyped API and needed no changes. createService()/rpc() take a RabbitTarget? now instead of a bare service name, with proxies cached per (interface, target) so an InstanceTarget call in a loop body is cheap. Verified against a real broker: FireAndForgetContractTest (4/4) and the KSP FireAndForgetValidationTest (2/2, via kotlin-compile-testing).

The internal packet layer - RabbitPacket/RabbitRequestPacket/RabbitResponsePacket, RpcCallRequestPacket, chunking, properties injection - stays, since RpcCallRequestPacket extends it; the plan's file list named the base classes for deletion, which would have taken the internal layer down with it. RabbitListenerHandlerManager no longer scans for @RabbitHandler-annotated methods via a hidden-class invoker: RpcCallRequestPacket is the only request type left, so it's wired directly. HandlerTemplate.java, HandlerMethodHandleProvider.java and the handler-registration exceptions go with the mechanism they served. Fixed a bug this surfaced: a throwing @FireAndForget handler was acked as if it had succeeded, because RpcServiceExecutor always encoded handler failures into an RpcCallResponsePacket that a fire-and-forget caller never reads. It now propagates the exception instead for a fireAndForget callable, which RabbitListenerHandlerManager's existing fire-and-forget branch already retries/dead-letters correctly. Nine tests rewritten from untyped packets to typed contracts, all verified against a real broker. Two scenarios dropped because the typed API has no equivalent: per-handler retry opt-out (no annotation carries it), and dead-lettering an unroutable message to an unregistered service (now a structured error response for two-way calls, a quiet ack for fire-and-forget).

Caught by +`RetryIntegrationTest`'s two retry-ladder cases, which failed until this fix — `FireAndForgetTest` +(Task 4) never exercised a throwing handler. + +**Deviation:** `@RabbitHandler(retry: Boolean)` gave each untyped handler its own retry opt-out; +`@RpcService`/`@FireAndForget` have no equivalent per-callable annotation, so +`RabbitListenerHandlerManager.retryEnabledFor()` is now hardcoded `true` for the sole remaining +request type. `RetryIntegrationTest`'s `` `a handler marked retry=false is attempted once and +dead-lettered` `` case is dropped — nothing in the typed API can express it. Also dropped: +`` `a message with no registered handler is dead-lettered, not lost` `` — an unregistered +`@RpcService` on a two-way call now gets a structured `NoSuchMethodError` response instead of a +silent nack-to-DLQ (a strictly more informative outcome), and on a fire-and-forget call it acks +quietly rather than dead-lettering, since `RabbitRpcServiceImpl.handleRequest` responds rather +than throwing when the service fqName is unknown. Both are behavior changes inherent in +collapsing the untyped API into RPC, not something Task 5 flagged explicitly. + +Verified for real (Docker reachable): every rewritten test passed against a live broker, +including the retry-ladder, competing-consumers, broker-restart, broker-loss, consumer-death, and +chunking suites. diff --git a/surf-eventbus-rabbitmq/surf-eventbus-rabbitmq-api/api/surf-eventbus-rabbitmq-api.api b/surf-eventbus-rabbitmq/surf-eventbus-rabbitmq-api/api/surf-eventbus-rabbitmq-api.api index d4c4514..65574db 100644 --- a/surf-eventbus-rabbitmq/surf-eventbus-rabbitmq-api/api/surf-eventbus-rabbitmq-api.api +++ b/surf-eventbus-rabbitmq/surf-eventbus-rabbitmq-api/api/surf-eventbus-rabbitmq-api.api @@ -10,12 +10,9 @@ public final class dev/slne/surf/eventbus/rabbitmq/api/SurfRabbitApi { public final fun getCbor ()Lkotlinx/serialization/cbor/Cbor;

Three compile-time rules: nullable return, never Unit, never @FireAndForget. New runtime types in bus-api/bus-core (QueryParameter/QueryInvoker/ QueryCallable/QueryServiceDescriptor, QueryParametersSerializer/ QuerySerializerCache) rather than reusing RPC's - those live in the rabbitmq modules, and Query is transport-agnostic bus infrastructure. Simplified relative to RPC: no per-call-site custom serializer support, just SerializersModule.serializer(KType) resolution. SurfEventBusImpl.query() now resolves the generated Descriptor via reflection and builds the client proxy, mirroring RabbitRpcServiceImpl's own descriptor lookup. Verified: QueryServiceValidationTest (KSP, 5/5) and QueryServiceClientTest (bus-core, 3/3, against a FakeQueryTransport - real dispatch is Task 7). The processor skips a private/file-local @QueryService interface rather than erroring, since QueryServiceRegistryTest already had private query fixtures for direct-registry tests that a generated (necessarily non-private) descriptor can't reference.

New types instead: `QueryParameter`/`QueryInvoker`/`QueryCallable`/`QueryServiceDescriptor` +(bus-api, `dev.slne.surf.eventbus.query.*`), `QueryParametersSerializer`/`QuerySerializerCache` +(bus-core). Simplified relative to RPC: no per-call-site `@Serializable(with = ...)` custom +serializer support (nothing in the codebase needs it for queries) — parameter and return-type +serializers resolve via `SerializersModule.serializer(KType)` directly. The new processor lives at +`dev.slne.surf.eventbus.ksp.processor.query` rather than under the existing (RabbitMQ-named) +`dev.slne.surf.eventbus.rabbitmq.processor` package, since Query has nothing to do with RabbitMQ. + +`SurfEventBusImpl.query()` now works: it resolves `Descriptor` via a `ClassValue`-backed +reflection cache (mirroring `RabbitRpcServiceImpl`'s `ServiceDescriptorCache`) and calls +`descriptor.createInstance(instanceId, json, transport)`. + +**Deviation:** the KSP processor skips (does not error on) a `private`/file-local +`@QueryService` interface instead of generating a descriptor for it. `QueryServiceRegistryTest` +already had `private interface Locator`/`FastLocator` fixtures (Plan 2, predating this generator) +for testing the registry directly, never through a generated proxy — a public-visibility +requirement would have broken those on the first build that turned on `kspTest` for +`surf-eventbus-bus-core`. Generating an `internal` descriptor referencing a private interface +doesn't compile anyway (Kotlin visibility rules), so skipping is the only option that doesn't +touch pre-existing test fixtures outside this task's scope. + +Verified: `QueryServiceValidationTest` (KSP, 5/5 — non-nullable return, `Unit` return, +`@FireAndForget` on a query, a valid nullable-suspend method, and a non-suspend method) and +`QueryServiceClientTest` (bus-core, 3/3 — the generated client asks and decodes a real answer, a +`null` answer means abstain, and the annotation's `timeoutMillis` lands in the descriptor) against +a `FakeQueryTransport`. Server-side dispatch (turning a registered implementation into answers) +is Plan 3 Task 7's job, not exercised here. diff --git

replace RedisRequest with typed @QueryService contracts QueryDispatcher now really dispatches: it resolves the generated descriptor for a frame's contract, decodes the payload, invokes the callable, and encodes a non-null result back. RedisQueryTransport carries queries and answers over Redis Pub/Sub - one channel per contract, one reply channel per instance, first reply wins. The old Redis request/ response API (RedisRequest/RedisResponse/RequestResponseBus/ RequestContext/HandleRedisRequest/RequestTimeoutException) is gone along with RedisApi.sendRequest()/registerRequestHandler(). QueryTransport.connect() gained an instanceId parameter (needed for the reply channel name, not available yet at withRedis() time). Verified against a real broker: RedisQueryTransportTest (6/6) and QueryDispatcherTest (4/4, using an internal rather than private contract since a private interface can't be referenced from its own generated descriptor).

The reply channel name is `surf.eventbus.reply.`, and +`instanceId` wasn't available at `RedisTransportProvider.query()`/`withRedis()` time (the builder +resolves it later, in `build()`) — passing it at `connect()` time, where `SurfEventBusImpl` already +has it, was the smallest fix that didn't require restructuring `SurfEventBusBuilder`'s ordering. + +**Deviation:** `QueryDispatcherTest`'s `Locator` contract is `internal`, not `private` as the +plan's own example code shows. A truly file-private interface can't be referenced from a +generated descriptor in a different file (Kotlin visibility rules, not a processor limitation), +and the KSP processor already skips codegen for private `@QueryService` interfaces (Task 6, for +`QueryServiceRegistryTest`'s fixtures) — so a private `Locator` here would get no descriptor at +all, and `QueryDispatcher.invoke()` needs one. `internal` keeps the contract out of the published +API while still being visible enough for the generator. + +**Verification pitfall worth recording:** the first draft of `RedisQueryTransportTest` used +`kotlinx-coroutines-test`'s `runTest`, copying `RedisEventTransportTest`'s style — and failed on +every case that raced a real cross-thread Redis round trip against `withTimeoutOrNull`. +`runTest`'s virtual-time scheduler auto-advances through a scheduled `delay` (which is what a +timeout is, internally) the moment nothing else is runnable *on that dispatcher*, even though a +real background thread (the Redisson listener) is about to complete the real work — so the +timeout fired instantly, before the real answer arrived. `RedisEventTransportTest` never hit this +because its assertions wait on a plain `Channel.receive()` with no explicit timeout on the +success path.

Also needed a +thread-safe `apis` list (`CopyOnWriteArrayList`, not `mutableListOf()`) — Redis listener callbacks +that build a fresh transport to answer run on a different thread than the test body and JUnit's +`@AfterAll`, and a plain `ArrayList` throws `ConcurrentModificationException` under that. + +Verified against a real broker: `RedisQueryTransportTest` (6/6 — one of three providers answers, +two providers answering has the first reply win, no answer within the timeout is `null`, no +provider at all is `null`, and only the asker receives the reply) and `QueryDispatcherTest` +(4/4 — answering, abstaining, throwing-is-audited-not-answered, and an unoffered contract is +ignored). diff --git a/surf-eventbus-bus/surf-eventbus-bus-api/src/main/kotlin/dev/slne/surf/eventbus/transport/QueryTransport.kt b/surf-eventbus-bus/surf-eventbus-bus-api/src/main/kotlin/dev/slne/surf/eventbus/transport/QueryTransport.kt index 13bc247..94311a5 100644 --- a/surf-eventbus-bus/surf-eventbus-bus-api/src/main/kotlin/dev/slne/surf/eventbus/transport/QueryTransport.kt +++ b/surf-eventbus-bus/surf-eventbus-bus-api/src/main/kotlin/dev/slne/surf/eventbus/transport/QueryTransport.kt @@ -1,8 +1,11 @@ package dev.slne.surf.eventbus.transport +import kotlinx.serialization.Serializable + /** * One question or answer on the wire. */ +@Serializable data class QueryFrame( val contract: String, val callable: String, @@ -18,7 +21,8 @@ data class QueryFrame( */ interface QueryTransport { -

Unlike RabbitMQ's per-field IntOr.Default merging, a YAML layer here wins or loses as a whole, since RedisConfig has no per-field "unset" sentinel - only the environment layer overrides individual fields. RedisApi.connect()/freezeAndConnect()/disconnect() are suspend now; the blocking internals (Redisson.create(), the INFO server eval, redisson.shutdown()) run under Dispatchers.IO. RedisTransportProviderImpl no longer eagerly connects at construction (impossible once connect() is suspend) - RedisEventTransport/RedisQueryTransport take an ensureConnected callback instead, and the provider supplies a Mutex-guarded one that connects the shared RedisApi exactly once, on whichever transport's first real operation reaches it first. SurfEventBusImpl.disconnect() deliberately does not tear down that shared RedisApi: RedisTransportLocator caches one RedisTransportProvider per JVM, so every SurfEventBus built with .withRedis() in one process shares the same Redis connection, and disconnecting it on one bus's disconnect() would break every other bus still using it. This completes Plan 3 (Tasks 1-8): full build green, both ABI checks clean.

surf-database-r2dbc's shading + +Recorded while implementing Task 2 of +`docs/superpowers/plans/2026-07-31-eventbus-4-audit-plattform-doku.md` on `feat/surf-event-bus`. +Task 1 (the audit contract and the five reporting paths) is done and committed; Task 2 (the +microservice that writes the reports to a database) is reverted and not started. + +## The blocker + +`dev.slne.surf:surf-database-r2dbc` is published as a single self-shaded `-all.jar` with Exposed +and R2DBC relocated under `dev.slne.surf.database.libs.*`. Checked versions 2.3.0 and 2.3.1 (the +only ones cached locally) by decompiling the jar directly: + +- The bytecode itself is relocated correctly — classes and methods really do live under + `dev.slne.surf.database.libs.org.jetbrains.exposed.v1.*`. +- The embedded Kotlin `@Metadata` annotations were **not** rewritten to match. They still encode + the pre-relocation names, e.g. `TransactionsKt`'s metadata says its owner is + `org/jetbrains/exposed/v1/r2dbc/transactions/TransactionsKt`, not + `dev/slne/surf/database/libs/org/jetbrains/exposed/v1/r2dbc/transactions/TransactionsKt`. + +Kotlin resolves extension functions and other top-level declarations through that metadata, not +raw bytecode. The mismatch means `suspendTransaction`, `insert`, `select`, `deleteWhere` and +similar top-level Exposed DSL functions are **unresolvable from Kotlin source** in a consuming +module, even though they exist and work fine from Java or via reflection. Members inherited +through a class hierarchy (`varchar()`, `integer()`, `bool()` on `AuditableLongIdTable`, for +example) resolve fine, because that path doesn't depend on the metadata being correct — only +top-level/extension-function resolution is broken. + +Separately: the plan's Task 2 build file assumes a `withSurfDatabaseR2dbc(...)` Gradle DSL helper. +It doesn't exist in the `surf-api-gradle-plugin` version actually resolvable here (`2.0.8` is the +only one cached, and its `StandaloneSurfExtension` has no such method) — a plain +`implementation("dev.slne.surf:surf-database-r2dbc:2.3.0")` works as a substitute for that part, +independent of the metadata issue above. + +## What this blocks + +Everything in Task 2 that needs to call into Exposed: `AuditMessagesTable` / +`AuditFailuresTable` / `AuditHeadersTable` (table *declarations* are fine — only their column +builders are used, all inherited), `AuditRepository.insert` / `.deleteOlderThan` (blocked — needs +`suspendTransaction`, `insert`, `select`, `deleteWhere`), and by extension `AuditServiceImpl`, +`AuditRetention` and `EventbusAuditMicroservice`, none of which were written. + +## What was reverted + +The `surf-eventbus-audit-microservice` module (build file, table declarations, repository, +`AuditServiceImpl`, test scaffolding) and the settings.gradle.kts / `surf-eventbus-audit` +buildscript changes that supported it were all removed from the working tree. None of it had +been committed. `surf-eventbus-audit-api` (Task 1, the `AuditService` contract) is untouched and +stays committed — it doesn't depend on surf-database. + +## Options for whoever picks this back up + +- Fix or bump `surf-database-r2dbc` so its shaded jar's Kotlin metadata matches the relocated + package (the actual bug, upstream). +- Write `AuditRepository` against raw R2DBC (`ConnectionFactory`/`Statement`) instead of the + Exposed DSL, sidestepping the broken metadata entirely. More verbose, but doesn't depend on a + fix landing upstream. +- Call the shaded Exposed functions via reflection. Not recommended — fragile and defeats the + point of using Exposed at all. + +## Where to resume + +`TODO(surf-eventbus-audit-microservice)` markers are left at the points where a client would +otherwise reach the (nonexistent) microservice: + +- `surf-eventbus-rabbitmq/surf-eventbus-rabbitmq-core/.../core/connection/RabbitConnectionImpl.kt`, + at the `auditSinkDelegate` construction — the client-side wiring is complete and correct + (Task 1), it just has nothing listening on `surf-eventbus-audit` yet. +- `docs/superpowers/plans/2026-07-31-eventbus-4-audit-plattform-doku.md`, Task 2 — steps + unchecked, with a pointer back to this note. diff --git a/docs/superpowers/plans/2026-07-31-eventbus-4-audit-plattform-doku.md b/docs/superpowers/plans/2026-07-31-eventbus-4-audit-plattform-doku.md index 9ee2865..9377a83 100644 --- a/docs/superpowers/plans/2026-07-31-eventbus-4-audit-plattform-doku.md +++ b/docs/superpowers/plans/2026-07-31-eventbus-4-audit-plattform-doku.md @@ -390,6 +390,12 @@ outage from becoming two, and the identity header groups ladder attempts." ## Task 2: Audit-Microservice +> **BLOCKED:** siehe `docs/superpowers/notes/2026-08-01-audit-microservice-blocked.md`. +> `surf-database-r2dbc` (2.3.0 und 2.3.1) shaded ihre Exposed-Abhängigkeiten, ohne die +> eingebetteten Kotlin-`@Metadata`-Annotationen auf die verschobenen Pakete anzupassen — dadurch +> sind `suspendTransaction`, `insert`, `select`, `deleteWhere` u.a. aus Kotlin-Quellcode heraus +> nicht auflösbar.

The design says what becomes one API and which plan-4 tasks ride along. surf-eventbus-test goes: its three modules pointed at the stale RabbitModule enum and at a surf-rabbitmq-paper plugin that no longer exists, and CI excluded them anyway. The unit and Docker tests in surf-eventbus-core cover the same ground and actually run.

Das Ergebnis +kompiliert (`compileKotlin compileTestKotlin` grün), aber die Naht ist überall sichtbar: zwei +parallele Vertragsmodelle für dasselbe Konzept, zwei KSP-Prozessoren, drei +`@RequiresOptIn`-Marker, zwei Konfigurationsstile, und Pakete, deren Namen aus der alten +Modulstruktur stammen statt aus der neuen. + +Dieses Dokument beschreibt, wie die Fläche zu **einer** API wird, und welche Reste aus Plan 4 +dabei mit erledigt werden. + +## Ausgangslage + +Zwei Module tragen alles: + +| Modul | Inhalt | +|---|---| +| `surf-eventbus-api` | Bus-API, RabbitMQ-API, Redis-API, Audit-Vertrag, Circuit Breaker | +| `surf-eventbus-core` | Bus-Implementierung, RabbitMQ-Transport, Redis-Transport | + +Dazu `surf-eventbus-ksp` und drei Plattform-Module. `surf-eventbus-test` wurde am 2026-08-01 +gelöscht: seine drei Module zeigten auf die veraltete `RabbitModule`-Enumeration und auf ein +Plugin `surf-rabbitmq-paper`, das es nicht mehr gibt, und `settings.gradle.kts` schloss sie auf +CI aus — die Unit- und Docker-Tests in `surf-eventbus-core` decken dasselbe ab und laufen +tatsächlich. + +## Was gebaut wird + +### 1. Ein Vertragsmodell für `@QueryService` und `@RpcService` + +Heute existiert jede Idee zweimal: + +| Query | RPC | +|---|---| +| `QueryServiceDescriptor` | `RabbitRpcServiceDescriptor` | +| `QueryCallable` | `RabbitRpcCallable` | +| `QueryParameter` | `RabbitRpcParameter` | +| `QueryInvoker` | `RabbitRpcInvoker` | +| `QueryCallableDefault`, `QueryParameterDefault` | `RabbitRpcCallableDefault`, `RabbitRpcParameterDefault` | +| `QueryParametersSerializer` | `CallableParametersSerializer` | +| `QuerySerializerCache` | `RpcSerializerCache` | +| — (roher `KType`) | `RabbitRpcType`, `RabbitRpcTypeDefault`, `RabbitRpcTypeKrpc` | + +`QuerySerializerCache` und `RpcSerializerCache` sind dieselbe Klasse mit einem anderen +Typparameter. `QueryParametersSerializer` und `CallableParametersSerializer` unterscheiden sich +in sechs Zeilen. + +Ein neues Paket `dev.slne.surf.eventbus.service` hält, was beide teilen: + +```kotlin +package dev.slne.surf.eventbus.service + +@InternalEventBusApi +interface ServiceDescriptor { + val simpleName: String + val fqName: String + val callables: Map> + + fun getCallable(name: String): ServiceCallable? +} + +@InternalEventBusApi +interface ServiceCallable { + val name: String + val returnType: ServiceType + val invoker: ServiceInvoker + val parameters: Array + + /** Ob dieser Aufruf `@FireAndForget` ist: keine Antwort wird gesendet oder erwartet. */ + val fireAndForget: Boolean +} + +@InternalEventBusApi +interface ServiceParameter { + val name: String + val type: ServiceType + val isOptional: Boolean + + /** Annotationen mit Ziel [AnnotationTarget.VALUE_PARAMETER]. */ + val annotations: List +} + +@InternalEventBusApi +interface ServiceType { + val kType: KType + + /** Annotationen mit Ziel [AnnotationTarget.TYPE]. */ + val annotations: List +} + +@InternalEventBusApi +fun interface ServiceInvoker { + suspend fun call(service: Service, arguments: Array): Any? +} +``` + +Jeder Transport erbt und ergänzt genau das, worin er sich unterscheidet — die Art, eine +Client-Instanz zu bauen: + +```kotlin +interface QueryServiceDescriptor : ServiceDescriptor { + val timeoutMillis: Long + fun createInstance(instanceId: String, json: Json, transport: QueryTransport): Service +} + +interface RpcServiceDescriptor : ServiceDescriptor { + /** Der Dienst aus `@RpcService(service = ...)`, oder leer, wenn `rpc(...)` ihn verlangt. */ + val defaultService: String + fun createInstance(serviceId: Long, api: SurfRabbitApi, target: RabbitTarget): Service +} +``` + +`ServiceType` trägt `kType` **und** Annotationen — die Form der RPC-Seite. Der Query-Pfad +benutzt heute den rohen `KType` und verliert dadurch `@Contextual` und +`@Serializable(with = ...)` an Parametern; mit `ServiceType` bekommt er beides. + +`ParametersSerializer` und `ServiceSerializerCache` ersetzen die je zwei Klassen. Die +RPC-Varianten gewinnen, weil sie Obermengen sind: optionale Parameter und kontextuelle +Serializer-Auflösung. + +`KotlinSerializerNameCache` bleibt eigenständig — es sucht nach Klassenname für den +Event-Codec-Pfad und ist keine Dublette, sondern ein anderer Zugriff. + +**Für Nutzer ändert sich nichts an den Annotationen.** `@QueryService` und `@RpcService` bleiben +getrennt: sie geben verschiedene Zusagen und haben verschiedene Validierungsregeln. + +### 2. Ein KSP-Prozessor + +Heute laufen zwei Prozessoren nebeneinander, mit je eigenem `Names`, `ClassNames`, +`MemberNames`, `Types.anyNullableArray`, eigener Modellfabrik und eigenem Descriptor-Codegen — +1616 Zeilen zusammen. + +``` +dev.slne.surf.eventbus.ksp + ServiceProcessor ein Lauf über beide Annotationen + ServiceProcessorProvider + model/ + ServiceModel, ServiceFunctionModel, ServiceParameterModel + ServiceModelFactory gemeinsames Einlesen und Validieren + QueryRules suspend, nullable, kein @FireAndForget + RpcRules suspend, @FireAndForget erlaubt + codegen/ + Names, ClassNames, MemberNames, Types + CallableCodegen, ParameterCodegen, TypeCodegen, InvokerCodegen + QueryDescriptorCodegen, QueryClientCodegen + RpcDescriptorCodegen, RpcClientCodegen +``` + +Die `META-INF/services`-Datei nennt danach **einen** Provider statt zwei. + +### 3. Pakete + +Der `.api`-Infix verschwindet, damit RabbitMQ aussieht wie Redis. `common` als Sammelbegriff +verschwindet, weil er nichts benennt. `internal` unter `api` in einem `-api`-Modul verschwindet, +weil `@InternalEventBusApi` diese Aussage bereits trägt. + +**`surf-eventbus-api`:** + +| Heute | Danach | +|---|---| +| `rabbitmq/api/**` | `rabbitmq/**` | +| `rabbitmq/api/internal/config/**` | `rabbitmq/config/**` | +| `rabbitmq/api/internal/RabbitMQInstance.kt` | entfällt (siehe 5) | +| `rabbitmq/api/rpc/{callable,descriptor,invoker,type}/**` | `service/**` (geteilt) + `rabbitmq/rpc/**` | +| `core/envelope/EventEnvelope.kt` | `transport/EventEnvelope.kt` | +| `common/circuitbreaker/**` | `circuitbreaker/**` | +| `common/serialization/**` | `serialization/**` | +| `common/platform/**` | `platform/**` | +| `common/config/LegacyEnvironmentGuard.kt` | `config/LegacyEnvironmentGuard.kt` | +| `redis/**` | unverändert | + +**`surf-eventbus-core`:** vier Geschwisternamen aus der alten Modulstruktur — +`rabbitmq/common/`, `rabbitmq/core/`, `rabbitmq/shared/`, `rabbitmq/rpc/` — werden zu flachen +Sachpaketen: + +``` +core/ SurfEventBusImpl, SurfEventBusBuilderImpl, SurfEventBusFactoryImpl, + RedisTransportLocator, RedisTransportProvider +core/{audit,dispatch,query,registry}/ +rabbitmq/{audit,connection,consumer,health,packet,publisher,retry,rpc, + serialization,topology}/ +redis/{bus,cache,config,credentials,sync,util}/ +``` + +Dateinamen folgen der Kotlin-Konvention: `byte-buf-extensions.kt` → `ByteBufExtensions.kt`, +`codec-extension.kt` → `CodecExtensions.kt`, `redis/util/util.kt` → `RedisUtils.kt`, +`exception/{api,connection,packet,protocol,request,serialization}.kt` → +`{Api,Connection,Packet,Protocol,Request,Serialization}Exceptions.kt`. + +Der Umbau ist ABI-brechend. Version 2.0 ist ohnehin nicht kompatibel zu 1.6.x, deshalb kostet er +nichts, was nicht schon bezahlt ist — aber die ABI-Dumps werden neu erzeugt und der +Rollout-Hinweis nennt ihn. + +### 4. Ein Marker statt drei + +| Heute | Aussage | +|---|---| +| `InternalEventBusApi` | ERROR, drei Ziele, ohne `@InternalAPIMarker` | +| `InternalRabbitMQ` | Standard-Level, sechs Ziele, mit `@InternalAPIMarker` | +| `InternalRedisAPI` | ERROR, kein `@Target`, Text nennt „surf-redis" | + +Danach: **`@InternalEventBusApi`**, ERROR, `@InternalAPIMarker`, alle sechs Ziele. Der +`abiValidation`-Filter in `surf-eventbus-api/build.gradle.kts` und die drei `optIn`-Zeilen im +Root-Build nennen danach eine Annotation. + +### 5. Symmetrie zwischen den Transporten + +Was ein Transport hat und der andere nicht, wird entweder für beide gebaut oder für keinen. + +**Konfiguration.** `GlobalRabbitMQConfig` (223 Zeilen) und `PluginRabbitMQConfig` (201 Zeilen) +sind dieselben vierzehn Felder mit derselben KDoc, zweimal; sie unterscheiden sich nur darin, +dass die eine `String`/`Int` benutzt und die andere `StringOrDefault`/`IntOr.Default`. Danach +gibt es **eine** `RabbitMQConfig` mit durchgehenden Sentinel-Typen und zwei Companions für die +beiden YAML-Orte. Die Standardwerte leben an einer Stelle. + +`CommonRabbitMQConfig` bekommt Kotlin-Properties statt `getHost()`/`isPersistRequests()`, damit +sie sich liest wie `RedisConfig`. + +Redis bekommt die vierte Schicht wirklich: `redisConfig` ruft heute +`resolveRedisConfig(global = …, plugin = null)` — die Plugin-Schicht ist verdrahtet, aber nie +gefüllt. + +`SURF_EVENTBUS_AUDIT_SERVICE` hängt heute an der RabbitMQ-Konfiguration, obwohl das Audit eine +Bus-Angelegenheit ist. Es zieht in eine Bus-Konfigurationsschicht. + +**Credentials.** `RedisCredentialsProvider` ist eine `ServiceLoader`-Naht mit genau einer +Implementierung; RabbitMQ baut seine Zugangsdaten direkt aus der Konfiguration. Danach liegen +beide unter `credentials/` mit gemeinsamem Obertyp, beide `@AutoService`, beide aus der +Konfiguration vorbelegt — die Naht existiert, damit ein Betreiber einen Secret-Store +einhängen kann, und das gilt für beide Transporte oder für keinen. + +Dabei wird ein Fehler behoben: `RedisCredentialsProviderImpl` baut `redis://@host`. +In einer URI steht vor dem `@` ohne Doppelpunkt der **Benutzername**, nicht das Passwort. +Richtig ist `redis://:@host`. + +**Instanzen.** `RabbitMQInstance` ist ein Interface im api-Modul mit einem `dataPath`. +`RedisInstance` ist eine abstrakte Klasse im core-Modul, die nebenbei eine Netty-Eventloop, zwei +Scheduler und einen Executor aufbaut. Beide beschreiben dasselbe: „die Plattform, in der dieser +Prozess läuft". + +Danach: **eine** SPI `dev.slne.surf.eventbus.platform.EventBusInstance` im api-Modul mit +`dataPath`, `getResourceAsStream` und `tryExtractPluginName`. Die Redis-Laufzeitobjekte ziehen +in ein `RedisRuntime` im core-Modul, wo Verhalten hingehört. Ein Plattform-Modul implementiert +danach **ein** Interface statt zwei — genau der Grund, warum Paper und Velocity heute eine +Rabbit-Instanz haben und keine Redis-Instanz. + +`StandaloneLifecycleHook` ist heute Rabbit-only und zieht auf die Bus-Ebene. + +**Ausnahmen.** RabbitMQ hat eine Hierarchie unter `SurfRabbitException`, Redis hat ein einzelnes +`RedisCodecException`, der Bus hat nichts. Danach: `SurfEventBusException` als Wurzel im +api-Modul, `SurfRabbitException` und ein neues `SurfRedisException` darunter. + +**Testinfrastruktur.** `RequiresDocker` existiert zweimal, wortgleich, in +`rabbitmq/common/testing` und `redis/testing`. Danach einmal. + +### 6. Hacks + +**Handgeschriebene `META-INF/services`.** `FakeStandaloneLifecycleHook` ist von Hand +registriert, weil `@AutoService` neben `surfEventbusKsp` auf derselben `kspTest`-Aufgabe einen +KSP2-Fehler auslöst (`KaInvalidLifetimeOwnerAccessException`). Die Ursache wird angegangen statt +umgangen: die Tests brauchen den `ServiceLoader` gar nicht. `SurfEventBusBuilder` hat mit +`withRedis(event, query)` bereits eine Testnaht; der Standalone-Hook und die Plattform-Instanz +bekommen dieselbe, und die Doubles werden übergeben statt gefunden. Lässt sich der KSP2-Fehler +danach nicht vermeiden, bleibt die Datei — aber der Kommentar nennt dann eine Reproduktion und +eine Entscheidung, nicht ein Achselzucken. + +**`FakeRedisInstance` wird gelöscht.** Die Klasse wird nirgends referenziert, und ihre KDoc +beschreibt eine Registrierung in `META-INF/services`, die es nicht gibt. + +**`AggregateCompletenessTest` wird gelöscht.** Er wurde geschrieben, um zu beweisen, dass ein +Aggregat-Modul seine Geschwistermodule weiterreicht. Bei einem Modul prüft er, dass Klassen in +ihrem eigenen Modul liegen, und kann nicht fehlschlagen. An seine Stelle tritt ein Test, der +etwas aussagt: **keine mit `@InternalEventBusApi` markierte Deklaration steht im ABI-Dump**. + +**`PackageNamingTest` und `RelocationBaseTest`** laufen über `Path.of("..")` und hängen damit +daran, dass das Arbeitsverzeichnis ein Modulordner ist. Sie suchen die Wurzel danach an einer +Markierungsdatei. + +**Zwei offene `TODO`s** werden aufgelöst: die Behandlung von +`SurfRabbitProtocolVersionMismatchException` in `RabbitListenerHandlerManager` und der Hinweis +zur Audit-Queue in `RabbitConnectionImpl`. + +**`AuditReports.kt`** aus Plan 4 Task 1 Step 9 fehlt: die fünf Meldepfade wurden ohne den +gemeinsamen Helfer verdrahtet. Er entsteht nach. + +**`.github/workflows/publish.yml`** nennt `surf-rabbitmq-velocity-*-all.jar` und +`surf-rabbitmq-paper-*-all.jar` — Artefaktnamen, die es nicht mehr gibt. Der Workflow lädt +heute nichts hoch, ohne dass es auffällt. + +### 7.

Der Meldeweg funktioniert bereits — die Meldungen haben nur noch kein Ziel. + +**Task 4** ist die sichtbarste Lücke: Paper und Velocity liefern je eine +`*RabbitMqInstance` und **keine** `RedisInstance`.

Die drei Verben mit je einem Beispiel und der Zusage darunter. +2. Die Aufgabenteilung als Tabelle — welche Zusage welchen Transport hat und was im Fehlerfall + passiert. +3. **An erster Stelle unter den Zusagen:** Events haben keine Durability. Wer offline ist, + verpasst sie, es gibt keine Wiederzustellung, und ein gescheiterter Handler hinterlässt eine + Audit-Zeile statt einer Wiederholung. Alles, was nicht verloren gehen darf, ist ein + `@FireAndForget`-Aufruf. +4. `@QueryService`-Anleitung mit der Falle: `null` heißt Abstinenz. Ein Vertrag muss „nichts + gefunden" von „nicht zuständig" unterscheidbar machen — bei `Boolean?` über `false`, sonst + über einen Ergebnistyp. +5. Konfiguration: die vier Schichten und die vollständige Tabelle der `SURF_EVENTBUS_*`-Variablen, + für **beide** Transporte, weil Redis seit Task 5 dieselben vier Schichten hat. +6. Redis-Sync-Strukturen: vor `freeze()` erstellen. Diese Falle bleibt und bekommt einen eigenen + Abschnitt, einmal statt zweimal. +7. Das Audit: welche Meldepfade es gibt, dass der schreibende Dienst noch nicht existiert, und + was das für einen Betreiber heute bedeutet. + +- [ ] **Step 3: Rollout-Notiz schreiben** + +`docs/rollout-2.0.md`, in der Reihenfolge, in der ein Betreiber sie braucht: + +1. **Env-Variablen umbenennen.** Vollständige Alt-nach-Neu-Tabelle für beide Transporte. Eine + gesetzte alte Variable ist ein Startfehler — das ist Absicht, nicht ein Bug. +2. **Alte Queues löschen.** `x-dead-letter-exchange` ist aus den Argumenten gefallen, und + Argumente sind Teil der Queue-Identität: die Neudeklaration einer bestehenden + `surf.service.*` scheitert mit `PRECONDITION_FAILED (406)`. Entweder die betroffenen Queues + löschen oder den Vhost neu aufsetzen: + ```bash + rabbitmqctl list_queues name | grep '^surf\.' + rabbitmqadmin delete queue name=surf.service. + ``` +3. **Das Audit hat noch kein Ziel.** Der Meldeweg steht, der schreibende Microservice ist + blockiert. Meldungen gehen mit `mandatory = false` raus und werden verworfen, solange seine + Queue nicht existiert — das kostet nichts und blockiert nichts, aber es heißt auch, dass eine + fehlende Audit-Zeile heute keine Aussage ist. +4. **Ein Plugin statt zwei.** Ein Server lädt `surf-eventbus-platform-paper` beziehungsweise + `-velocity` und damit eine Netty-Kopie statt zwei. Die alten Plugins `surf-rabbitmq-paper` + und die surf-redis-Plugins müssen vorher weg. +5. **Gemeinsam deployen.** Wire-Format und API sind inkompatibel zu 1.6.x/1.5.x; gemischter + Betrieb funktioniert nicht. + +- [ ] **Step 4: Prüfen, dass die README keine falschen Versprechen macht** + +Gegen `docs/superpowers/specs/2026-07-29-surf-eventbus-design.md` lesen und vier Dinge +bestätigen: dass nirgends „durable" über Events steht, dass `InstanceTarget` als „für +namentlich bekannte Server" beschrieben ist und nicht als Server-zu-Server-Kanal, dass das Audit +als best effort beschrieben ist — keine Zeile ist keine Garantie, dass nichts passiert ist —, +und dass keine Umgebungsvariable ohne `SURF_EVENTBUS_`-Präfix mehr vorkommt: + +```bash +grep -n "SURF_RABBITMQ_\|SURF_REDIS_" README.md docs/rollout-2.0.md +``` +Expected: keine Ausgabe. + +- [ ] **Step 5: Der letzte vollständige Lauf** + +Run: `./gradlew clean build -PskipIntegration` +Expected: SUCCESS. + +Run: `./gradlew checkLegacyAbi` +Expected: SUCCESS. + +Run: `./gradlew :surf-eventbus-core:test` +Expected: Container-Tests SKIPPED — und genau so wird es berichtet. + +- [ ] **Step 6: Commit** + +```bash +git add -A +git commit -m "docs: rewrite the README and add the 2.0 rollout note + +The README still called this project surf-rabbitmq and documented +SURF_RABBITMQ_* variables whose old names are a startup error since plan 1. + +The rollout note leads with the three things that break silently otherwise: +renamed environment variables, queue arguments that cannot be redeclared, and +an audit path whose writer does not exist yet." +``` + +--- + +## Self-Review + +**Spec-Abdeckung (Spec-Abschnitt → Task):** + +| Spec | Task | +|---|---| +| 1 Ein Vertragsmodell (`service/`, `ParametersSerializer`, `ServiceSerializerCache`) | 2 | +| 2 Ein KSP-Prozessor | 3 | +| 3 Pakete und Dateinamen | 4 | +| 4 Ein Marker statt drei | 1 | +| 5 Konfiguration: eine `RabbitMQConfig`, Kotlin-Properties, Redis-Plugin-Schicht | 5 Steps 5–6 | +| 5 Credentials für beide, URI-Fehler | 5 Steps 1–4 | +| 5 `EventBusInstance`, `RedisRuntime`, `StandaloneLifecycleHook` bus-weit | 5 Step 7 | +| 5 Ausnahmewurzel | 5 Step 8 | +| 5 `RequiresDocker` einmal | 5 Step 9 | +| 6 `META-INF/services`-Hack, `FakeRedisInstance`, `AggregateCompletenessTest` | 6 Steps 1–4 | +| 6 CWD-abhängige Tests, `AuditReports`, zwei TODOs, `publish.yml` | 6 Steps 5–8 | +| 7 Plan-4 Task 4 Plattform-Module | 7 | +| 7 Plan-4 Task 5 Container-Suiten | 8 | +| 7 Plan-4 Task 6 Dokumentation | 9 | +| 7 Plan-4 Task 2 als blockiert weitertragen | 9 Step 1 | +| „Wie geprüft wird": Test gegen `common`, `rabbitmq.api`, kebab-case | 4 Step 1 | + +**Typkonsistenz:** `ServiceCallable`, `ServiceParameter`, `ServiceType`, `ServiceInvoker` und +die vier `*Default`-Klassen werden in Task 2 Step 3 definiert und in Task 3 Step 5 vom Codegen +emittiert — unter denselben Namen. `RpcServiceDescriptor` (Task 2 Step 5) ist der Name, den +Task 3 Step 5 in `ClassNames.rpcServiceDescriptor` einträgt; `RabbitRpcServiceDescriptor` +kommt nach Task 2 nirgends mehr vor. `EventBusInstance` (Task 5 Step 7) ist der Typ, den +Task 7 Step 3 dreimal implementiert und den `RabbitMQConfig` (Task 5 Step 5) für seinen +`dataPath` benutzt. `StandaloneLifecycleHook` zieht in Task 4 Step 3 nach +`dev.slne.surf.eventbus.platform` und ist dort der Typ, den `withStandaloneHook` in Task 6 +Step 1 nimmt. `ParametersSerializer` und `ServiceSerializerCache` (Task 2 Step 8) liegen in +`dev.slne.surf.eventbus.service.serialization` und werden von Task 3 Step 5 unter genau diesem +Paket referenziert. + +**Reihenfolgeabhängigkeiten:** Task 1 vor 4, weil sonst jede Datei zweimal angefasst wird. +Task 2 vor 3, weil der Prozessor auf die Typen zeigt.

one contract model for @QueryService and @RpcService Descriptor, callable, parameter, type and invoker existed twice, once per transport, differing in names and in nothing else. Query parameters gain type annotations along the way, so @Contextual now reaches them.

One walk, one model, two backends where the output genuinely differs. The shared emitters are the RPC ones, so a query parameter now carries its type annotations into the descriptor instead of an empty list.

java.nio.file.Path @AutoService(RabbitMQInstance::class) From 71215f81ceddf1e793f3c403777eedb27530e6b9 Mon Sep 17 00:00:00 2001 From: Ammo Date: Sat, 1 Aug 2026 14:52:58 +0200 Subject: [PATCH 77/84] refactor!: one config for the whole bus, and the same shape for both transports One eventbus.yml with a rabbitmq and a redis section, in two layers (eventbus.yml, eventbus-plugin.yml), replacing GlobalRabbitMQConfig, PluginRabbitMQConfig, CommonRabbitMQConfig, RabbitEnvironment and a separate RedisConfig in another module. Every field is a sentinel, so env > plugin > global > default now resolves per field for Redis too - a redis plugin file with one key in it used to discard everything the global file set. PluginRabbitMQConfig resolved each of its fourteen fields through GlobalRabbitMQConfig.getConfig(), a mutable process-wide singleton, so what a plugin config resolved to depended on which file had been loaded last. Both layers are passed to the resolver explicitly instead. The file type (EventBusConfig, sentinels) and the resolved type (EventBusSettings, values) are now named apart. RabbitMQSettings is a data class, so a test double is a constructor call rather than thirteen overrides. Also: one EventBusInstance SPI instead of RabbitMQInstance plus an abstract RedisInstance that built a Netty event loop, with the runtime objects moved to RedisRuntime; one credentials seam for both transports; one exception root; one RequiresDocker. StandaloneRabbitMqInstance and StandaloneLifecycleHookImpl leave surf-eventbus-core, where a standalone class never belonged - which is what made core's own unit tests read a never-initialised dataPath. Fixes the Redis URI: redis://secret@host names a user called 'secret'; the password belongs after a colon. Removes LegacyEnvironmentGuard and the plugin config migration, both outdated.

StandaloneLifecycleHook no longer resolves a requiredService in a companion, so absence is NoOp and the double has no reason to exist; withStandaloneHook injects one where a test does want to observe the lifecycle. AggregateCompletenessTest asserted that this module's classes are on this module's classpath, which cannot fail. InternalNotInAbiTest asks the opposite and useful question. PackageNamingTest and RelocationBaseTest no longer depend on the working directory. AuditReports replaces four hand-built AuditReport call sites that each filled in the same six identity fields; a wrong messageUuid turned one message that failed four times into four unrelated incidents. The protocol-version-mismatch TODO is resolved as UNDESERIALIZABLE: the peer speaks another protocol and will speak it again, so there is nothing to retry. The publish workflow named jars that stopped existing at the rename.

The audit suite is missing on purpose - its microservice is still blocked - but DatabaseContainerExtension exists so unblocking it is the only remaining step. Contrary to the plan's premise, Docker IS reachable here, so these ran. That found two defects, both older than this branch and both reproduced at 256e950: - RedisComponentProviderImpl.tryExtractPluginNameFromClass threw ServiceConfigurationError with no platform registered, so RedisApi.create(uri) failed in any process without one. The twelve existing RedisEventTransportTest and RedisQueryTransportTest cases had therefore never passed. The name only labels a connection in CLIENT LIST; it now falls back. - EventSubscriptionRegistry never called trySetAccessible. A public method on a non-public class is listed by Class.methods but is not callable from another package, so the dispatcher threw IllegalAccessException on every delivery. Since a throwing handler is contained by design, the only trace was one EVENT_HANDLER_FAILED row per event: registered, reported healthy, never ran. Pinned by NonPublicListenerTest, which needs no container. Full run: 275 tests, 0 failures, 0 skipped.

It now leads with the three verbs and, under the promises, with the one that costs data if assumed otherwise: events have no durability. Anything that must not be lost is a @FireAndForget rpc call, not an event. The rollout note leads with the two steps that break silently: renamed environment variables (a leftover old name is not read, so the process comes up healthy pointing at localhost) and queue arguments that cannot be redeclared. It also says plainly that the audit path has no writer yet, so a missing audit row is not evidence that nothing went wrong. Plan 4 Task 2 is unblocked: surf-database-r2dbc 2.3.2 relocates its @Metadata correctly. Verified by compiling suspendTransaction, insert, select and deleteWhere against it inside surf-eventbus-core rather than by reading bytes - the type descriptors already looked correct in 2.3.1. Recorded in the note, including that deleteWhere lives in .r2dbc and not .core.

From 809f16f1081082e52e6d2a9f15e189033eaa5f67 Mon Sep 17 00:00:00 2001 From: Ammo Date: Sat, 8 Aug 2026 15:07:10 +0200 Subject: [PATCH 82/84] fix: close the silent failures the audit found, and let CI catch the next ones MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit `docs/audit-2026-08-01-repository.md` is a full read of the tree at e4863ad. Its critical findings share one shape: a documented guarantee that does not hold, and fails without saying so. This commit acts on them. Nothing ran the tests. `publish.yml` only triggered on `version/*`, so 21 commits of breaking rewrite had never been built by anything but a laptop — and `DockerAvailableCondition` turning a missing daemon into a skip meant a local run could report green while verifying nothing. `ci.yml` now builds and tests every push and PR, and passes `-PrequireIntegration`, which turns that skip into a failure. `docker-compose.yml` and `docs/development.md` cover the local side. The silent failures: - A `suspend` `@SurfSubscribe` handler passed validation and could never run — the dispatcher invokes with one argument, a suspend method's JVM signature takes two, and the `IllegalArgumentException` became one `EVENT_HANDLER_FAILED` row per event. Now rejected at registration, which is the honest answer until the dispatcher can call one. - `RedisEventTransport.disconnect()` did not unsubscribe. Disposing the `Disposable` from `.subscribe()` is a no-op; only `removeListener(id)` detaches. Subscribes now await the listener id — which also closes the race where an event published right after `connect()` returned could beat the in-flight SUBSCRIBE, and Pub/Sub does not redeliver. - `EVENT_HANDLER_FAILED`, `QUERY_HANDLER_FAILED` and `UNKNOWN_EVENT_TYPE` never reached the audit service: the dispatchers were hardcoded to `LoggingAuditSink` with no injection point. The sink is now a constructor parameter. - The audit correlation id was regenerated on the first hop, so every message's first failure grouped under a different UUID than the retry carried. - A registered `@QueryService` with no query transport was stored, never subscribed, and turned every query into a silent abstention. - Handler failures reported `InvocationTargetException` instead of what the handler actually threw. The Lua that reads the server OS out of `INFO server` never worked. `[^\\r\\n]` reached Lua verbatim, Lua collapsed it to `[^\rn]` — a literal backslash, `r`, `n`, since Lua patterns escape with `%` — so `os:Linux 5.15…` matched `"Li"`. The match succeeded with the wrong value, so `contains("Windows")` was never true and the `os == null` fallback never ran either. `RedisOsDetectionTest` runs it against a real Redis, since a Kotlin reimplementation of a Lua pattern would only test the reimplementation. Reactor and Redisson are out of the published ABI. `SyncStructure`, `SimpleRedisCache` and `SimpleSetRedisCache` extended `reactor.core.Disposable` and `Initializable` returned `Mono` — in a jar whose shadow config excludes `reactor.core`, so the supertype named in the signature was one no consumer could resolve. They now use `RedisDisposable` and `suspend fun init()`; Reactor stays the mechanism inside the core module. `RedisApi`'s Redisson clients and its `RedisURI`/`Path` `create` overloads are `@InternalEventBusApi` now, for the same reason — the shadow jar relocates `org.redisson`, so those signatures named types no consumer could resolve; `createForAddress` is what remains public. The two unused `Mono.asDeferred` extensions are gone — one violated Reactive Streams §2.13, the other duplicated `awaitSingle`. The ABI dump is regenerated to match. `warnedTypes` is bounded now; its key came off the wire, so any peer could grow this process's heap by publishing random type names. `WireConstantsTest` pins the two identifiers that changed without appearing in the API — the AMQP version header and the Redis sync key prefix. The sync prefix is the dangerous one: a 1.6.x process left running against the same Redis keeps a disjoint copy of every sync structure and nothing reports it. `rollout-2.0.md` now says so.

Almost every +non-obvious decision carries a KDoc explaining what it replaced and why. That is rare and valuable, +and it is the main reason this audit could be thorough. + +It is also a codebase mid-consolidation, and the seams show. Two former projects (`surf-rabbitmq`, +`surf-redis`) were merged under one name and one package root, but only the *naming* was +unified — the two halves still disagree on concurrency model (coroutines vs Reactor), service +lookup (five different idioms), configuration (per-plugin layering works for Rabbit, silently does +not for Redis), lifecycle, error handling, and testing strategy. The KDoc frequently describes the +intended end state rather than the current one, which makes the drift harder to see, not easier. + +The most serious problems are not stylistic. Several documented guarantees do not hold in the +current code: suspend event handlers can never run, the Redis event transport never unsubscribes, +the audit-report correlation id is regenerated on the first hop, and event/query audit rows never +reach the audit service at all. None of these are visible without reading the code, because each +failure mode is *silent* by design — which is exactly the class of bug this project's own README +warns about. + +| Dimension | Score | One-line justification | +|---|---:|---| +| Architecture | 5/10 | Clear vision, clean module split; undermined by god classes, 5 service-lookup idioms, two concurrency paradigms, impl types in the public ABI | +| Maintainability | 5/10 | Excellent rationale comments; but ~1,900 lines of near-duplicate code, three copies of descriptor lookup, two copies of transport detection | +| Scalability | 5/10 | Sound broker topology; ~50 threads/process, hardcoded pools, per-event allocation in the dispatcher hot path, wildcard subscribers receive all fleet traffic | +| Test Coverage | 4/10 | 277 tests, strong on protocol/topology/retry; zero on ~2,000 lines of Redis cache/sync, publisher, consumer, connection provider. **No CI runs any of them.** | +| Kotlin Idiomatic Usage | 6/10 | Mostly idiomatic; spoiled by `Pair` as a domain type, `Array` in interfaces, a `@Serializable` class implementing `CoroutineScope`, partial `equals` on a data class | +| Performance | 5/10 | Careful in the chunker and stream parser; `waitForConfirmsOrDie` serialises publishing, `EventTopics.matches` allocates per segment per event, 3 collection copies per received event | +| Security | 5/10 | Good: no `x-death` trust, bounded chunk metadata, type-load guard.

No CI runs the tests + +`.github/workflows/publish.yml` is the only workflow. It triggers on push to `version/*` and calls a +shared build-publish-release workflow. **There is no pull-request build, no test run, no ABI check, +no lint.** This branch — 21 commits of breaking rewrite — has never been verified by anything but a +developer's local machine, and `-PskipIntegration` plus "Docker not available → skip" means even a +local run can silently verify nothing (`RequiresDocker.kt:30`, message: *"integration test skipped, +NOT verified"* — the author knew). + +*Impact:* every other finding in this document could have been caught, or could regress tomorrow. +*Fix:* a `ci.yml` on `pull_request` + `push` running `./gradlew check` with a Docker-enabled runner; +fail the build when the integration tag is skipped on CI (`-PrequireIntegration`). +*Complexity:* low. *Worth doing:* unconditionally, first. + +### C2. `suspend` `@SurfSubscribe` handlers register successfully and can never run + +`EventSubscriptionRegistry.register` (line 30-31) explicitly detects suspend handlers — it strips the +trailing `Continuation` parameter before counting arguments, so `suspend fun onX(e: E)` passes +validation and is registered. `EventDispatcher.invoke` (line 110-112) then calls +`method.invoke(listener, event)` with exactly one argument. A suspend method's JVM signature takes +two. Every delivery throws `IllegalArgumentException: wrong number of arguments`, is caught by the +containment block at line 73, and produces one `EVENT_HANDLER_FAILED` audit row per event. + +The handler looks registered, `freeze()` passes, `connect()` passes, and nothing ever runs. This is +precisely the failure mode `EventTopics`' KDoc says validation exists to prevent. + +*Fix:* either reject suspend handlers at registration with a clear message, or support them properly +(`kotlin.reflect.full.callSuspend`, or require a non-suspend adapter). Rejecting is the smaller +change and the honest one; supporting them is what users will expect from a coroutine-first bus. +*Complexity:* low to reject, medium to support. *Worth doing:* yes — silent no-op handlers are the +worst possible outcome. + +### C3. `RedisEventTransport.disconnect()` does not unsubscribe, and `connect()` races the subscription + +Two defects in one class, both visible by comparing it to its sibling `RedisQueryTransport`, which +gets both right: + +- **Subscription is not awaited.** `subscribeJson`/`subscribeBinary`/`subscribeJsonPattern`/ + `subscribeBinaryPattern` (lines 73-109) call `.subscribe()` on the `addListener` Mono and move on. + `RedisQueryTransport.subscribeQuery` (line 89) calls `.awaitSingle()` and its comment states the + reason verbatim: *"a query or reply published right after connect() must not race an in-flight + SUBSCRIBE, or the message is gone for good — Pub/Sub has no redelivery."* The same hazard applies + to events and is not handled. +- **Disconnect does not remove listeners.** `disconnect()` disposes the `Disposable` returned by + `.subscribe()`. That subscription has already completed (it delivered the listener id); disposing + it is a no-op. The Redis listener stays attached for the life of the `RedisApi`. The query + transport keeps `(topic, listenerId)` pairs and calls `removeListener(id)` — the correct approach. + +*Impact:* events published immediately after `freezeAndConnect()` may be lost; a disconnected bus +keeps receiving and dispatching events into a scope that is about to be cancelled; in tests, buses +from an earlier test answer a later one (the `RedisBusSuite` KDoc already blames this class of +problem on "the harness"). +*Fix:* mirror `RedisQueryTransport` exactly — `awaitSingle()` the listener id, track `(topic, id)`, +`removeListener` on disconnect. Better: extract the shared subscribe/publish plumbing so the two +cannot diverge again (see X2). +*Complexity:* low. *Worth doing:* yes. + +### C4. The audit correlation id is regenerated on the first failure, breaking the grouping it exists for + +`AuditMessageIdentity.of(properties)` returns the `x-surf-audit-message-id` header, or **a fresh +random UUID** when absent (`AuditMessageIdentity.kt:18-19`). In `RetryPublisher.handleFailure`: + +```kotlin +val messageId = AuditMessageIdentity.of(properties) // random UUID #1 — used to stamp attempt 2 +auditSink.report(reports.handlerFailed(properties, …)) // base() calls of() again → random UUID #2 +``` + +`AuditReports.base` (line 86) independently calls `AuditMessageIdentity.of(properties)`. On the first +failure — the only time the header is absent, and therefore every message's first failure — the +report carries a different id than the one stamped onto the retry. The whole point of the mechanism, +stated in its own KDoc (*"the database would show four unrelated incidents instead of one message +that failed four times"*), fails on hop one. + +Related: `AuditMessageIdentity.stamp()` exists, is tested (`AuditMessageIdentityTest`), and is used +by **nothing in production** — `RetryPublisher.withNextAttempt` re-implements it inline. The test +suite validates a function the product does not call. + +*Fix:* resolve the id once and thread it through (`AuditReports.base(messageUuid, …)`); delete the +inline copy in `withNextAttempt` in favour of `stamp()`. +*Complexity:* low. *Worth doing:* yes. + +### C5. Event and query audit rows never reach the audit service + +`SurfEventBusImpl` hardcodes `auditSink = LoggingAuditSink` for both dispatchers (lines 56, 65) with +no injection point. `RabbitAuditSink` — the class that actually publishes `AuditReport`s to +`surf-eventbus-audit` — is constructed only inside `RabbitConnectionImpl` and is only reachable from +the RabbitMQ paths. So on a bus with `.withRabbit().withRedis()`, `EVENT_HANDLER_FAILED`, +`QUERY_HANDLER_FAILED` and `UNKNOWN_EVENT_TYPE` are logged and dropped. + +The README's audit table lists `HANDLER_FAILED` and `QUERY_HANDLER_FAILED` without distinction and +says every loss "writes an audit report instead". For three of seven `AuditKind` values that is not +true today. + +*Fix:* pass the sink into `SurfEventBusImpl` from the builder — `rabbitApi?.connection?.auditSink ?: +LoggingAuditSink` — or introduce a `CompositeAuditSink`. Note this also removes the last reason +`SurfEventBusImpl` cannot be unit-tested with a fake sink. +*Complexity:* low. *Worth doing:* yes. + +### C6. Redis reads its per-plugin config from the wrong directory, and from a process-wide singleton + +`RedisConfigAccess.kt`: + +```kotlin +val redisConfig: RedisSettings by lazy { + val dataPath = EventBusInstance.orNull()?.dataPath // the PLATFORM plugin's folder + … + resolveEventBusConfig( + global = EventBusConfigFiles.global(dataPath), + plugin = EventBusConfigFiles.plugin(dataPath), // …used for the plugin layer too + ).redis +} +``` + +Compare `SurfRabbitApiBuilder.resolveConfig` (line 103-107), which correctly passes +`platform.dataPath` for the global layer and the *consumer plugin's* `dataPath` for the plugin layer. +For Redis both layers read the same file in the same directory, so `eventbus-plugin.yml` in a +plugin's own folder is never read. The README states: *"Both transports use all four layers, +identically."* They do not. + +Worse, `redisConfig` is a top-level `by lazy` — a process-wide singleton fixed on first touch. This +is the exact anti-pattern `EventBusConfigFiles`' KDoc says was deliberately removed: + +> *"There is deliberately no `getConfig()` here. The old `GlobalRabbitMQConfig.getConfig()` was a +> mutable process-wide singleton … Both layers are passed to `resolveEventBusConfig` explicitly +> instead."* + +Rabbit obeys that rule; Redis has the singleton the rule was written against. It is also why the +production `withRedis()` path is untestable — `RedisBusSuite`'s KDoc says so outright, and every +Redis suite therefore exercises the `withRedis(event, query)` test seam instead of the real wiring. + +*Fix:* delete the global; resolve `RedisSettings` where `RabbitMQSettings` is resolved (in the +builder) and pass it into `RedisTransportProviderImpl`/`RedisComponentProviderImpl` as a parameter. +This single change fixes the layering bug, removes the singleton, and makes the production path +testable. +*Complexity:* medium (touches the SPI signatures). *Worth doing:* yes — highest architectural value +per unit of effort in the repo. + +### C7. The published API exposes relocated third-party types + +`surf-eventbus-api/api/surf-eventbus-api.api` — the frozen ABI — contains: + +``` +public fun redisURI ()Lorg/redisson/misc/RedisURI; +public final fun getRedisson ()Lorg/redisson/api/RedissonClient; +public abstract fun decode (Lio/netty/buffer/ByteBuf;)… +public abstract interface class …/SimpleRedisCache : …, reactor/core/Disposable +public abstract class …/AbstractCodec : org/redisson/client/codec/BaseCodec, … +``` + +Meanwhile `build.gradle.kts:43-57` relocates `org.redisson` → `dev.slne.surf.eventbus.libs.redisson` +and `io.netty` → `dev.slne.surf.eventbus.shaded.io.netty` in every shadow jar, and the api module +publishes `from(components["shadow"])`. A consumer compiling against the published artifact gets +public signatures naming relocated classes; a consumer compiling against the unrelocated module gets +different ones. `reactor.core` is *excluded* from the redisson dependency (`build.gradle.kts:35`) yet +appears in public supertypes. + +*Impact:* the ABI validation this module runs is validating a surface that is not stable across +packaging. Redisson upgrades become breaking API changes for consumers. +*Fix (in order of preference):* (a) remove Redisson/Netty/Reactor from the api module's public +surface — `RedisApi.redisson`/`redissonReactive`/`redisOsType` become internal, `RedisCredentials +Provider` returns a plain `RedisAddress`, `Initializable`/`SyncStructure` become `suspend`-based; (b) +failing that, stop relocating Redisson and declare it a normal `api` dependency. +*Complexity:* high. *Worth doing:* yes — this is the difference between a library and a bundle. + +### C8. `SurfEventBusBuilder.build(environment)` accepts a parameter that is ignored + +`SurfEventBusBuilder.kt:36` declares `fun build(environment: Map? = null)`. The only +implementation, `SurfEventBusBuilderImpl.build` (line 47), never reads it. It is a public API +promise — "you can inject the environment" — that does nothing, and the resolver it would feed +(`resolveEventBusConfig(environment = …)`) does accept exactly such an override. + +*Fix:* wire it through to `resolveEventBusConfig`, or delete the parameter. Wiring it is better: it +gives the config layering a test seam it currently lacks. +*Complexity:* low. *Worth doing:* yes. + +### C9. Redis OS detection is broken by over-escaped Lua + +`RedisApi.fetchRedisOs` (line 391-410): + +```kotlin +val lua = """ + local info = redis.call('INFO', 'server') + return string.match(info, 'os:([^\\r\\n]+)') +""".trimIndent() +``` + +Kotlin raw strings do not process escapes, so Lua receives `'os:([^\\r\\n]+)'`. Lua's string literal +turns `\\` into a single backslash, giving the pattern `[^\r\n]` where `\` is a *literal backslash* +— Lua patterns escape with `%`, not `\`. The character class therefore excludes backslash, `r` and +`n`, not CR/LF. `os:Linux 5.15…` matches `"Li"`; `os:Windows…` matches `"Wi"`. + +Consequently `os.contains("Windows")` is never true and `redisOsType` stays `null` on Windows. The +`os == null` branch that would have caught it is also never taken, because the match succeeds — with +the wrong value. + +*Fix:* `'os:([^\r\n]+)'` (single backslashes in the raw string). Add a unit test asserting the +extracted value for representative `INFO server` output. +*Complexity:* trivial. *Worth doing:* yes. + +### C10. Blocking connection establishment inside a coroutine, inside a monitor + +`RabbitConnectionProvider.awaitOpen` is `suspend` and calls `connection()` directly (line 83). +`connection()` takes `synchronized(lock)` and calls `factory.newConnection(connectionName)` — a +blocking TCP connect + AMQP handshake, bounded only by `connectionTimeout` (default 30 s). + +This runs on whatever dispatcher the caller is on: `Dispatchers.Default` (a work-stealing pool sized +to CPU count) via `RabbitPublisher.publish` and `RabbitConsumer.getChannel`. Under a broker outage, +several publishers can park `Dispatchers.Default` threads for 30 s each while holding a monitor. + +*Fix:* `withContext(Dispatchers.IO) { … }` around the connect, and prefer a `Mutex` over +`synchronized` so the suspension point is legal. Both are small changes with large blast-radius +reduction. +*Complexity:* low. *Worth doing:* yes. + +--- + +## High Priority + +### H1. `SurfEventBus.disconnect()` has no failure containment + +```kotlin +override suspend fun disconnect() { + eventTransport?.disconnect() + queryTransport?.disconnect() + rabbitApi?.disconnect() +} +``` + +`connect()` immediately above it wraps each step in `runCatching` on failure — the author clearly +reasoned about half-connected states. `disconnect()` does not: the first throw leaks the Redis query +subscription, the AMQP connection, four consumer threads, two publisher threads and the audit sink's +scope. On Paper this happens during server shutdown, where it produces the "leaked RabbitClient" +warning and a **10-second `Thread.sleep`** (`RabbitClient.kt:238`). +*Fix:* same `runCatching` pattern, rethrowing the first failure with the rest suppressed. + +### H2. `RabbitAuditSink`'s scope and drain loop are never cancelled + +`RabbitAuditSink.kt:39` creates `CoroutineScope(Dispatchers.Default + SupervisorJob())` and launches +a `for (next in pending)` drain loop in `init`. Nothing cancels the scope or closes the channel — +`RabbitConnectionImpl.disconnect()` closes only the client. Every `SurfRabbitApi` ever constructed +leaks one coroutine and one channel for the life of the JVM. On a Paper server that reloads plugins, +this also pins the plugin classloader. +*Fix:* make it `AutoCloseable`/`Closeable`, close the channel and cancel the scope from +`RabbitConnectionImpl.disconnect()`. + +### H3. Unbounded caches keyed by remote-supplied strings + +- `EventTypeResolver.cache` — `ConcurrentHashMap`, keyed by `envelope.type` + straight off the wire, with negative results cached deliberately and no bound. +- `EventDispatcher.warnedTypes` — `ConcurrentHashMap.newKeySet()`, same key, same lack of + bound. +- `QueryDispatcher.DescriptorCache` — keyed by `Pair`; holds **strong + references to classloaders**, preventing plugin unload on Paper. + +Any peer (or anything that can publish to the Redis channel) can grow two unbounded maps by +publishing envelopes with random `type` values. There is no authentication on the Redis channels. +*Fix:* bounded Caffeine caches with a size cap (the project already depends on Caffeine everywhere); +weak classloader keys for the descriptor cache. + +### H4. Double retry-publish race on the RPC timeout path + +`RabbitListenerHandlerManager.handleRequest`, `replyTo != null` branch: `handlerJob.invokeOnCompletion` +(line 201) launches `retryOrDeadLetter` when the handler fails, *and* the `TimeoutCancellation` +catch (line 222-228) calls `retryOrDeadLetter` after cancelling `requestJob`. Cancelling the job +triggers the completion handler, so on timeout both paths can run. `RabbitAck` is idempotent +(`settled` CAS), but `RetryPublisher.handleFailure` is not: two audit reports and two copies of the +message on the retry tier, which the origin queue then redelivers twice. +*Fix:* one settle path. An `AtomicBoolean handled` guarding `retryOrDeadLetter`, or restructure so +the completion handler is the only caller. + +### H5. Publisher confirms serialise all publishing on two threads + +`RabbitPublisher.publish` runs `channel.basicPublish` followed by +`channel.waitForConfirmsOrDie(5s)` inside `withContext(dispatcher)`, where `dispatcher` is a +**single-threaded executor** (line 19-25). With the default `publisherPoolSize = 2`, the process can +have at most two unconfirmed publishes in flight, each blocking a dedicated OS thread for the full +broker round-trip. + +For an RPC-heavy service this is the throughput ceiling and it is invisible — the config comment says +*"a few fast publishers can already saturate the broker"*, which is true only because the +implementation cannot use more than one at a time each. +*Fix:* asynchronous confirms (`addConfirmListener` + a `ConcurrentSkipListMap` keyed +by delivery tag), keeping the channel confinement but not the blocking wait. Expect a large +throughput win; medium complexity, and worth benchmarking with the existing JMH harness first. + +### H6. `EventDispatcher.dispatch` allocates three collections per received event + +```kotlin +val subscriptions = registry.subscriptions() // full list copy +val eventClass = typeResolver.resolve( + typeName = envelope.type, + known = subscriptions.map { it.eventClass }, // second list + loaders = subscriptions.mapTo(mutableSetOf()) { …classLoader } // a set +) +val matches = registry.subscriptionsFor(eventClass, envelope.topic) // filter → fourth +``` + +Then `subscriptionsFor` calls `EventTopics.matches(pattern, topic)` per subscription, which splits +both strings and recurses with `drop()` — allocating a fresh list per pattern segment. + +The registry is frozen before any event is dispatched. All of this is computable once at `freeze()`. +*Fix:* at `freeze()`, precompute the immutable subscription list, the known-class set, the loader +set, and a compiled representation of each pattern (`List` segments, or a small state +machine). Cache `(type, topic) → matches` in a bounded map. This is the single hottest path in the +event half of the bus and is currently the most allocation-heavy code in the repo. + +### H7. Sync-structure writes are fire-and-forget; failures are logged, not reported + +`AbstractStreamSyncStructure.writeToRemote` / `writeBatchToRemote` end in `.subscribe({ … }, { e -> +log.atWarning() … })`. `SyncMap.put`, `SyncSet.add`, `SyncList` mutations therefore return +successfully whether or not the write reached Redis. A caller has no way to learn that a write was +lost — no exception, no return value, no audit row. + +For a library whose README is emphatic that events have no durability *and says so loudly*, having +sync-structure writes silently drop is inconsistent with the project's own honesty standard. +*Fix:* make the mutators `suspend` and await the script result, or return a `Deferred`/`Mono` the +caller can await. At minimum, route failures to the `AuditSink` rather than a warning. + +### H8. `RpcService` KDoc documents an API that no longer exists + +`RpcService.kt` — the most-read annotation in the public surface — carries ~100 lines of KDoc +referencing `ClientRabbitMQApi.createRpcService`, `ServerRabbitMQApi.registerRpcService`, +`serverApi.registerRpcService(…)`, `clientApi.createRpcService()`, none of +which exist. The final example shows `rabbit.rpc(service = "surf-factions-staging")` +— there is no `service` parameter on `rpc`; the signature is `rpc(target: RabbitTarget?)`. A user +copying it gets a compile error. + +`surf-eventbus-ksp/README.md` (342 lines) is worse: titled `surf-rabbitmq-ksp`, documents +`RabbitRpcServiceDescriptor`, `RabbitRpcCallable`, `RabbitMQApi`, and does not mention +`@QueryService` at all — the module's other half. +*Fix:* rewrite both against the current API. Add a `docs` check that compiles KDoc samples (Dokka +does not do this; a small `samples/` source set that is compiled does). + +### H9. Five different service-lookup idioms for one concern + +| Location | Idiom | Timing | Absence | +|---|---|---|---| +| `SurfEventBusFactory` | `by lazy { requiredService() }` | lazy | throws | +| `EventBusInstance.instance` | `by lazy { requiredService() }` | lazy | throws | +| `EventBusInstance.orNull()` | `ServiceLoader.load(...).firstOrNull()` | **every call** | null | +| `RedisComponentProvider` | top-level `val = requiredService()` + `companion : X by provider` | class-init | throws | +| `RabbitCredentialsProvider`, `RedisCredentialsProvider`, `RabbitMQConnectionFactory` | same | class-init | throws | +| `RabbitRpcServiceFactory` | `companion { val instance = requiredService() }` | class-init | throws | +| `StandaloneLifecycleHook.discover()` | `ServiceLoader.load(...).firstOrNull()` | every call | null | + +Three of these initialise eagerly at class load, which makes the class unloadable in any process +without the registration — the exact problem `StandaloneLifecycleHook`'s KDoc describes and solves +*only for itself*. `EventBusInstance.orNull()` re-runs a full `ServiceLoader` scan on every call and +is called from `RedisComponentProviderImpl.tryExtractPluginNameFromClass`, i.e. once per `RedisApi` +creation. + +Two of them additionally expose both `companion object : X by provider` *and* a redundant +`val INSTANCE get() = provider`. +*Fix:* one `internal object Services { inline fun required(): T; inline fun +optional(): T? }` with lazy caching and an explicit classloader, used everywhere. Delete the +`INSTANCE` duplicates. + +### H10. Three copies of "find the generated descriptor" + +| File | Cache | Key | +|---|---|---| +| `SurfEventBusImpl.QueryDescriptorCache` | `ClassValue` | `Class` | +| `QueryDispatcher.DescriptorCache` | `ConcurrentHashMap` | `Pair` | +| `RabbitRpcServiceImpl.ServiceDescriptorCache` | `ClassValue` | `Class` | + +All three implement `"${type.packageName}.${type.simpleName}Descriptor"`, all three catch +`ClassNotFoundException` and `LinkageError`, all three return `null` — and they disagree on caching +strategy, classloader choice, and (in `QueryDispatcher`) whether the initial `Class.forName` failure +is caught at all (it is not — it escapes `computeIfAbsent`). + +The naming convention is also duplicated in the generator (`ServiceModelFactory` line 134: +`peerClass("${simpleName}Descriptor")`). Four places must agree; nothing enforces it. +*Fix:* one `internal object ServiceDescriptors { fun of(type: Class<*>): ServiceDescriptor<*>? }` in +the api module, with the name-mangling constant shared with the KSP module via a plain string +constant and a test asserting round-trip. + +### H11. Exception hierarchy does not hold + +`SurfEventBusException`'s KDoc: *"The root of everything this project throws on purpose."* Outside it: + +- `SurfRabbitApiNotFrozenException`, `SurfRabbitApiAlreadyFrozenException` → `IllegalStateException` + (with KDoc justifying the exclusion) +- `CircuitOpenException` → `IllegalStateException` +- `RabbitConnectionGenerationChangedException` → `IllegalStateException` +- Bare `error()` / `check()` / `require()` in `SurfEventBusImpl` (7×), `RabbitRpcServiceImpl` (4×), + both registries, `RedisApi` (5×), `AbstractStreamSyncStructure` (4×) + +A consumer cannot catch "the bus failed". Additionally `serialVersionUID` is present on +`ConnectionExceptions.kt` (all five), `SurfRabbitServiceUnavailableException`, `CircuitOpenException` +and `RabbitConnectionGenerationChangedException`, and absent on all of `PacketExceptions.kt`, +`RequestExceptions.kt`, `SerializationExceptions.kt` — no rule, just history. + +*Fix:* decide one rule and apply it. Recommendation: everything the library throws deliberately +extends `SurfEventBusException`; state-precondition violations get a +`SurfEventBusStateException : SurfEventBusException` that *also* has the `IllegalStateException` +semantics documented; add `serialVersionUID` everywhere or nowhere (nowhere is fine — these are not +serialized) and enforce with Detekt. + +### H12. Exception *file* names are actively misleading + +- `ProtocolExceptions.kt` contains **zero** protocol exceptions — one frozen-state exception. +- `PacketExceptions.kt` contains **all seven** `SurfRabbitProtocol*` exceptions. +- `ApiExceptions.kt` contains the other half of the frozen-state pair — so the two + frozen-state exceptions, which cross-reference each other in their KDoc, live in two differently + named files. +- `SurfRabbitProtocolVersionMismatchException` lives in `SerializationExceptions.kt`. + +*Fix:* `StateExceptions.kt`, `ProtocolExceptions.kt`, `SerializationExceptions.kt`, +`ConnectionExceptions.kt`, `RequestExceptions.kt`, each holding what its name says. + +### H13. `freeze()` validates events but not queries or RPC + +`SurfEventBusImpl.freeze()` produces an excellent error when `@SurfSubscribe` handlers exist without +`.withRedis()`. It performs no equivalent check for: + +- query services registered via `registerService` with no query transport → they are stored in + `queryRegistry`, `connect()` skips subscription entirely, and every query to this process is a + silent abstention; +- `rpc()` proxies — checked at call time, not freeze time, so a missing `.withRabbit()` surfaces at + the first production call rather than at startup. + +*Fix:* symmetric checks in `freeze()`, with error messages in the same shape as the event one. + +### H14. `SurfRabbitApi.freeze()` is not thread-safe and the lifecycle is one-shot + +`private var frozen = false` (line 78) with a check-then-act in `freeze()`, no `@Volatile` — while +`SurfEventBusImpl`, `EventSubscriptionRegistry`, `QueryServiceRegistry` and `RedisApi` all correctly +mark theirs `@Volatile`. One class out of five. + +Separately, `disconnect()` calls `scope.cancel(...)`, so the api cannot be reconnected — and +`SurfEventBusImpl.connect()`'s failure path calls `rabbitApi?.disconnect()`, permanently killing the +scope of an api that never connected. A retry of `connect()` after a transient broker outage cannot +work. +*Fix:* `AtomicBoolean` (or `@Volatile` + CAS) for `frozen`; create the scope in `connect()` rather +than in the constructor, or make the rollback path not cancel it. + +--- + +## Medium Priority + +### M1. Naming is inconsistent in four distinct ways + +**Class prefixes.** `SurfRabbitApi` vs `RedisApi`; `SurfRabbitApiBuilder` vs no Redis builder; +`SurfRedisException` vs `SurfRabbitException` (consistent) but `RedisExceptions.kt` holds it while +`SurfRabbitException.kt` is its own file. Pick one: either everything user-facing is `Surf*`-prefixed +or nothing is. Given the package root is already `dev.slne.surf.eventbus`, the prefix is redundant — +`RabbitApi`/`RedisApi`, `RabbitException`/`RedisException` would be cleaner, but that is a bigger +break. Minimum viable fix: `SurfRedisApi`. + +**Acronym casing.** `RabbitMQConnection`, `RabbitMQSettings`, `RabbitMQSection`, +`RabbitMQMicroserviceHealthContributor` vs `RabbitMqVersion`. One file disagrees with eleven. + +**Product name in wire-visible identifiers** (these are the expensive ones — changing them later is +a protocol break): +- `RabbitMqVersion.AMQP_HEADER = "x-surf-rabbitmq-version"` +- `AbstractSyncStructure.NAMESPACE = "surf-redis:sync:"` (Redis key prefix) +- `RabbitClient` error text: *"These plugins probably did not call `RabbitMQApi.disconnect()`"* — a + class that has not existed since before this branch. + +**Type-name leakage from a former dependency.** `ServiceTypeKrpc` (and `ClassNames.serviceTypeKrpc` +in the generator) — "krpc" is not a concept in this project. + +*Fix:* rename now, while 2.0 is already a wire break, and add a test asserting the header/namespace +constants (a rename after release is a rollout step). + +### M2. `ServiceDefaults.kt` does not contain service defaults + +It contains `ServiceTypeDefault`, `ServiceTypeKrpc`, `ServiceParameterDefault`, +`ServiceCallableDefault` — four public implementation classes. Nothing in it is a "default value". +Similarly `QueryTransport.kt` declares `QueryFrame` (a wire type) alongside the transport interface, +and `RabbitConnectionProvider.kt` declares `RabbitConnectionGenerationChangedException`. +*Fix:* one public type per file where the file is the type; `ServiceImplementations.kt` or +individual files for the four above. + +### M3. Two implementations of Netty transport detection + +`RabbitClient.Companion.transport` (`NettyTransport` data class, lines 46-85) and +`TransportInfo.detect()` (lines 23-47) perform byte-identical `IoUring → Epoll → KQueue → NIO` +detection, producing two different types with two different string labels ("IoUring" in both, +coincidentally). Both are then used to build separate `MultiThreadIoEventLoopGroup`s. +*Fix:* one `internal object NettyTransports { val detected: NettyTransport }` in core, exposing the +`IoHandlerFactory`, the channel class, the Redisson `TransportMode` and the label. + +Related: `TransportInfo` is a `data class` whose components are an `IoHandlerFactory` and an enum — +`equals`/`hashCode`/`copy` on a factory instance are meaningless. Make it a plain class or an enum +with properties. + +### M4. Thread budget is large, hardcoded, and unowned + +Per process, with both transports enabled: + +| Source | Threads | Configurable | +|---|---:|---| +| `RabbitClient.sharedEventLoopGroup` | 8 | no (hardcoded) | +| `RabbitClient.sharedConsumerExecutor` | 16 | no (hardcoded) | +| `RabbitPublisher` (one per pool slot) | 2 | via `publisherPoolSize` | +| `RabbitConsumer` (declare, reply, service, instance) | 4 | no | +| `RedisRuntime.eventLoopGroup` | 16 | no (hardcoded) | +| `RedisRuntime.streamPollScheduler` | ≤8 | no | +| `RedisRuntime.ttlRefreshScheduler` | 2 | no | +| Redisson connection pool | 8 | no (hardcoded in `createRedissonConfig`) | + +≈ 56 threads before any application work, on a Paper server that also runs the game. The `declare` +consumer (`RabbitConnectionImpl.connect` line 221) is used once, for topology declaration, and then +holds a thread and a channel forever. +*Fix:* derive pool sizes from `Runtime.availableProcessors()` with config overrides in +`RabbitMQSettings`/`RedisSettings`; close the `declare` consumer after `connect()`; consider sharing +one event loop group between Rabbit and Redisson (both are Netty). + +### M5. Redis has 4 config fields; RabbitMQ has 14 + +`RedisComponentProviderImpl.createRedissonConfig` hardcodes connection pool size (8), minimum idle +(2), retry attempts (10), retry delay, connect timeout (5 s), ping interval (10 s), TCP keepalive +parameters and RESP3. None are configurable, while RabbitMQ exposes prefetch, publisher pool, +timeouts, persistence and chunking. An operator cannot tune Redis at all. + +Also `RedissonConfigDetails.serializerModule` is passed in and **never read** by the only consumer — +a dead field in an `@InternalEventBusApi` data class. + +### M6. `EventBusSettings` / `RedisSettings` have a non-deterministic default + +`RedisSettings.clientName: String = EventBusDefaults.redisClientName()` where +`redisClientName() = "surf-eventbus-client-${UUID.randomUUID()}"`. Because it is a default argument, +every `RedisSettings()` gets a different value, so `RedisSettings() != RedisSettings()` and +`EventBusSettings() != EventBusSettings()`. Data classes whose `equals` depends on construction time +are a trap in tests and in any dedupe/caching. +*Fix:* `clientName: String? = null`, resolved to a generated name at the point of use. + +### M7. Three hand-written `toString()` overrides for redaction + +`RabbitMQSection`, `RedisSection`, `RabbitMQSettings`, `RedisSettings` and `RabbitCredentials` each +hand-write a `toString` listing every field, purely to print `password=`. Fourteen fields +in one of them. Adding a field and forgetting the `toString` silently drops it from every log line; +adding a *secret* field and forgetting it leaks it. +*Fix:* a `@JvmInline value class Secret(private val value: String) { override fun toString() = +"" ; fun reveal() = value }`. All five `toString` overrides then disappear and the data +class default is correct and complete. This also removes the risk in `redisUriOf`, which currently +embeds the password into a `RedisURI` whose `toString` the project does not control. + +### M8. `AuditReport` is a data class with a deliberately partial `equals` + +`AuditReport.equals` compares 4 of 25 properties (`messageUuid`, `attempt`, `kind`, `payload`). +Two reports differing in service, instance, timestamp, handler, exception and stacktrace compare +equal. The KDoc explains the `ByteArray` handling but not the omissions. +*Fix:* full `equals` (a `@Serializable` DTO should have value semantics), plus an explicit +`fun sameIncident(other: AuditReport): Boolean` if the partial comparison is genuinely needed. The +current shape will produce a wrong answer the first time someone puts reports in a `Set`. + +### M9. `AuditReports.base` reads three AMQP properties nothing ever writes + +```kotlin +originService = properties.appId ?: serviceName // appId is never set +originInstance = properties.headers?.get("x-surf-instance") // never written +payloadEncoding = properties.contentEncoding // never set +messageType = properties.type // never set +``` + +`RabbitConnectionImpl.properties()` sets only `deliveryMode`, `correlationId`, `replyTo`, +`messageId`, `expiration` and the version header. So four report fields are permanently null/fallback. +`AuditReportsTest` constructs `BasicProperties.Builder().appId(...)` by hand and passes — testing a +path production never takes. +*Fix:* set `appId = serviceName`, `x-surf-instance = instanceId`, `type = packet class name`, +`contentEncoding = "cbor"` in `properties()`; or delete the fields. Setting them is cheap and makes +the audit rows useful. + +### M10. `EventDispatcher` reports `payloadEncoding = "JSON"` for binary events + +Both report builders hardcode `payloadEncoding = "JSON"` and `payload = envelope.payload?…`, but for +a `BusEventCodec` event the envelope payload is `null` and the body is the binary frame. Binary +events produce audit rows claiming JSON with no payload. + +### M11. `AuditKind` and the README disagree + +README table: `HANDLER_FAILED`, `QUERY_HANDLER_FAILED`, `UNROUTABLE`, `UNDESERIALIZABLE`, +`CHUNK_SERIES_EXPIRED` (5). Enum: those plus `UNKNOWN_EVENT_TYPE` and `EVENT_HANDLER_FAILED` (7). +The README says `HANDLER_FAILED` covers "an RPC **or event** handler threw"; the code has a separate +`EVENT_HANDLER_FAILED`. A consumer building a dashboard from the README misses two kinds. + +### M12. `Pair, CompletableDeferred<…>?>` as a domain type + +`RabbitConnectionImpl.pendingRequests` is a Caffeine cache of that pair. Every use site reads +`.first`/`.second` and null-checks the deferred — five times in the file. The deferred is never +actually null: only `awaitResponse` inserts, always with one. So the nullability is dead and forces +a null check at every touch point. +*Fix:* `private data class PendingRequest(val request: RabbitRequestPacket<*>, val response: +CompletableDeferred)`. + +### M13. `RabbitConnectionImpl` is a god class (616 lines, 11 responsibilities) + +Connection lifecycle, audit sink construction, retry publisher, circuit breaker, return listener, +two chunk assemblers, two serializer caches, correlation id generation, pending-request bookkeeping, +reply consumption, request consumption, AMQP property construction. `send()` and `awaitResponse()` +duplicate the same chunk-decision + publish-loop block. +*Fix (composition, not inheritance):* `RpcCaller` (correlation ids, pending map, `sendRequest`, +`send`), `RpcResponder` (request consumers, reply publishing), `ReplyChannel` (reply queue + +endpoint state), leaving `RabbitConnectionImpl` as the assembly point. Extract +`publishChunked(exchange, routingKey, body, properties, mandatory)` to kill the duplication. + +### M14. `RabbitRequestPacket` is a wire DTO that is also a `CoroutineScope` and a response channel + +`@Serializable abstract class RabbitRequestPacket : RabbitPacket(), CoroutineScope` with +`override var coroutineContext by Delegates.notNull()` and a `@Transient CompletableDeferred`. +Constructing one on the client side and calling `launch {}` on it throws +`IllegalStateException: Property coroutineContext should be initialized before get`. + +Also `RabbitPacket.timestamp = OffsetDateTime.now()` is serialised on every packet +(`@Contextual`) and read by nothing. +*Fix:* split into `RpcRequest` (pure data) and a server-side `RequestContext(scope, response)` the +executor holds. Delete `timestamp` or start using it. + +### M15. `RabbitAck.nack` and `RabbitAck.nackIfUnsettled` are identical + +Byte-for-byte the same implementation. `reject` is dead (declaration only). +*Fix:* delete `nackIfUnsettled` (keep `nack`, which already only acts when unsettled) and `reject`. + +### M16. `RetryPolicy`'s ladder is encoded twice + +`MAX_RETRIES = 3` and a `when (attempts) { 0 -> TEN_SECONDS; 1 -> ONE_MINUTE; 2 -> FIVE_MINUTES; +else -> DeadLetter }`. Adding a tier to `RetryTier` requires editing three places (enum, `when`, +`MAX_RETRIES`) plus `EventBusDefaults.RETRY_TTL_MILLIS`, and only one of those is checked +(`declareRetryTiers` requires matching sizes). +*Fix:* `RetryTier.entries.getOrNull(attempts)?.let(RetryDecision::Retry) ?: DeadLetter`, and +`MAX_RETRIES get() = RetryTier.entries.size`. + +Also: `retryEnabled` is threaded through `RabbitListenerHandlerManager.retryEnabledFor()` (which +ignores its parameter and returns a literal `true`), `RetryPublisher.handleFailure` and +`RetryPolicy.decide`. Three layers carrying a constant. Delete or implement. + +### M17. Two logging frameworks + +Everything uses `dev.slne.surf.api.core.util.logger()` (Flogger) except `RpcServiceExecutor`, which +uses `net.kyori.adventure.text.logger.slf4j.ComponentLogger`. One file out of ~40. + +### M18. Reactor and coroutines coexist without a boundary + +`Mono`/`Flux`/`Disposable`/`Scheduler` throughout the Redis half (`SyncStructure`, `Initializable`, +`SimpleRedisCache`, `AbstractSyncStructure`, `LuaScriptExecutor`, `RedisExpirableUtils`, +`RedisStreamsUtils`, `DisposableAware`); `suspend`/`CoroutineScope`/`Deferred` everywhere else. The +boundary is crossed ad hoc with `awaitFirstOrNull`, `awaitSingle`, and two blocking `.block()` calls +(`RedisApi:732,802`, `AbstractSyncStructure:64`) — the last of which throws if it lands on a Reactor +non-blocking thread. + +`RedisUtils.kt` even contains a hand-written Reactive-Streams `Subscriber` implementing +`Mono.asDeferred()` next to a KDoc saying *"Prefer `asDeferred(scope)`"* — two implementations of a +function `kotlinx-coroutines-reactor` already provides. Its `onComplete` throws +`NoSuchElementException`, which violates the Reactive Streams specification (§2.13). +*Fix:* make Reactor an internal implementation detail. The public `SyncStructure`/`SimpleRedisCache` +surfaces become `suspend`. This is a prerequisite for C7 anyway. + +### M19. `RedisApi` is a 810-line god class with stale documentation + +- 70 lines of class KDoc describing `RedisService`, `registerRequestHandler`, `subscribeToEvents`, + `RequestContext` — none of which exist. The example will not compile. +- Six `create` overloads, one of them `@Deprecated(level = ERROR)` and therefore uncallable — it can + be deleted outright. +- `getCallingPluginName()` uses `getCallerClass(1)`, a fixed stack depth, from inside a companion + reached through up to two other overloads. From `RedisTransportProviderImpl`'s + `RedisApi.create()` the attributed "plugin" is effectively arbitrary. +- `lateinit var redisson` / `redissonReactive` public with private setters — touching them before + `connect()` throws `UninitializedPropertyAccessException` rather than a domain error. +- `initializables`/`disposables` are Caffeine caches with **weak keys** used as a lifecycle registry: + a sync structure the caller does not retain can be collected before `init()` ever runs. +- `disconnect()` returns early when `!isConnected()`, so a bus that froze but never connected leaks + both coroutine scopes. + +### M20. `RabbitClient.closeSharedResources()` sleeps 10 seconds on the shutdown path + +When any client is still active — which is the *normal* case on Paper, because nothing tracks the +buses plugins created — it logs two warnings, blocks for 10 s, then logs a stack trace per leak. On a +game server this is 10 s of shutdown hang, on the main thread if that is who called it. +*Fix:* register buses for shutdown and disconnect them properly; drop the sleep, or make it a short, +configurable grace period. + +### M21. `decodeOrNull` throws + +`RabbitPacketChunking.decodeOrNull` returns `null` for three conditions and throws +`SurfRabbitProtocol*Exception` for six others. Callers reading the name will not guard. +*Fix:* rename to `decodeChunk`, or return a sealed `ChunkDecodeResult`. + +### M22. Chunk header size is specified twice + +`CHUNK_HEADER_SIZE` (line 47) and the `exactSize` expression in `encodeChunk` (line 230) compute the +same value from the same seven terms, with a comment saying *"remember to update decodeOrNull if +changing this"* — an instruction to a human where the compiler could do it. + +### M23. `QueryDispatcher.failureReport` puts instance ids in service-name fields + +```kotlin +originService = frame.originInstanceId // an instance id +reportedByService = instanceId // an instance id +``` +`EventDispatcher` does this correctly with a real `serviceName`. The query dispatcher does not +receive one. + +### M24. KSP: annotations are matched by simple name; the default timeout is duplicated + +`ServiceModelFactory.readServiceAttribute`/`readTimeoutAttribute`/`fireAndForget` all match +`shortName.asString() == "RpcService"` / `"QueryService"` / `"FireAndForget"`. Any same-named +annotation from another package matches. `ContractKind` already carries the fully qualified names — +use them. + +`DEFAULT_TIMEOUT_MILLIS = 5_000L` in the processor duplicates `QueryService(timeoutMillis = 5_000)` +in the api. Changing the annotation default silently desynchronises generated descriptors. + +### M25. KSP: asymmetric contract rules and asymmetric generation + +`QueryRules.acceptsContract` silently skips private/local contracts (no log at all — the developer +gets a runtime *"no generated descriptor found"* much later). `RpcRules.acceptsContract` returns +`true` unconditionally, so a private `@RpcService` generates a descriptor referencing a private type +→ a compile error in generated code. + +`RpcDescriptorCodegen` applies `addInternalDeprecation()` + `suppressInternalDeprecation()`; +`QueryDescriptorCodegen` applies neither. `QueryClientCodegen` is instantiated inside +`QueryDescriptorCodegen`; `RpcClientCodegen` is instantiated in `ServiceProcessor`. + +### M26. KSP generates `!!` + +`QueryClientCodegen:93` emits `val callable = __descriptor__.getCallable("x")!!`. The descriptor is +generated from the same model, so it cannot be null — which is exactly why it should be +`getCallable("x") ?: error("generated descriptor is missing callable x")`, or the callables map +should be a `Map` accessed with `getValue`. + +--- + +## Low Priority + +- **L1.** Redundant self-package imports in `RabbitConnectionImpl` (5), `RabbitClient` (3), + `RabbitListenerHandlerManager` (4), `RabbitRpcServiceImpl` (5), `RabbitPacketSerializer` (3), + `RpcServiceExecutor` (1), `EventTransport` (1), `SurfEventBusBuilderImpl` (1). A linter would + remove all of them. +- **L2.** Fully-qualified inline type references where an import exists elsewhere in the same file + or module: `java.util.UUID.randomUUID()` (`RabbitConnectionImpl:286`), + `java.util.concurrent.ConcurrentHashMap` (`QueryDispatcher:95`), `java.util.ServiceLoader` + (`EventBusInstance:33`), `java.util.Optional` (`VelocityEventBusInstance`), `java.nio.file.Path` + (`RedisBusSuite:81`), `java.lang.reflect.Method` (`EventDispatcher:110`). +- **L3.** German in an English codebase: `EventSubscription.displayName` KDoc (*"Klasse#Methode"*); + every plan/spec document under `docs/superpowers/` is German while the README, KDoc and rollout doc + are English. +- **L4.** Dead code confirmed by grep (declaration is the only reference): + `SurfRabbitConnectionFailedException`, `SurfRabbitConnectionClosedException`, + `EventTypeResolver.isKnownUnresolvable`, `RabbitConsumer.reject`, + `RabbitConnectionImpl.EMPTY_BYTE_ARRAY`, `ksp/codegen/Util.kt::applyIf` (the file's only + declaration), `RedisEventTransport.log`, `SurfRabbitPublishException(attempts, cause)`, + `RabbitRpcService.unregisterService`, `CircuitBreakerRegistry.names()`/`resetAll()`, + `RabbitAuditSink.droppedCount()`, `SurfEventBusImpl.dataPath` (suppressed `unused`). + Production-dead but test-referenced: `AuditMessageIdentity.stamp`, `QueryServiceRegistry.timeoutOf`. +- **L5.** `ServiceDescriptor.getCallable(name)` duplicates `callables[name]`; every generated + descriptor implements both. +- **L6.** `ServiceCallable.parameters: Array` — a mutable array in a public + interface. `List` is the Kotlin answer. +- **L7.** `RabbitIdentity` is a plain class with a hand-written `toString` and no `equals`/`hashCode` + — a `data class` in all but declaration. +- **L8.** `RabbitConnectionProvider.createChannel` casts to `RecoverableChannel` and returns + `Channel` — the cast has no effect. +- **L9.** `EventTypeResolver.Optional` shadows `java.util.Optional` by name. +- **L10.** `RabbitPublisherPool` names publishers `"0"`, `"1"` → two clients in one JVM produce + identically named `rabbit-publisher-0` threads. +- **L11.** `RabbitTopologyDeclarer.declareRetryTiers` uses `tier.queueName` as both queue *and* + exchange name; the property name says queue. +- **L12.** `EventSubscriptionRegistry.patterns()` is recomputed by both `exactTopics()` and + `wildcardPatterns()` → three passes where one suffices. +- **L13.** `EventSubscriptionRegistry.register` iterates `javaClass.methods` without filtering + bridge/synthetic methods, and does not dedupe — registering the same listener twice doubles + delivery silently. +- **L14.** `RabbitRpcServiceImpl.handleRequest` answers an unknown service with `NoSuchMethodError` + (a JVM linkage `Error`) for what is a routing miss. +- **L15.** Caffeine used as a plain concurrent map with no eviction policy in `RabbitRpcServiceImpl` + (`rpcServices`, `proxies`) — `ConcurrentHashMap` is clearer and cheaper. +- **L16.** `ServiceSerializerCache` is instantiated per component (`QueryDispatcher`, + `RabbitRpcServiceImpl`, `RpcServiceExecutor`, and once per generated query client). Same for + `KotlinSerializerCache` (four `ClassValue` instances). One shared cache per `SurfEventBus` would do. +- **L17.** `ParametersSerializer.descriptor` uses one fixed serial name + (`"surf.eventbus.ParametersSerializer"`) for every callable of every contract. +- **L18.** `RabbitPacketChunkAssembler` defaults `serviceName = ""`, `instanceId = ""` — blank + identity fields in audit rows if a caller forgets. Make them required. +- **L19.** `RabbitPacketChunkAssembler` defines a private `NoOpAuditSink` while `LoggingAuditSink` + exists; a third sink implementation for the same interface. +- **L20.** `RetryPublisher.handleFailure` constructs a new `AuditReports` on every failure; the + constructor arguments are fields. Hoist it. +- **L21.** `EventBusPlatformInstance.onEnable()` is an empty `@MustBeInvokedByOverriders` method. +- **L22.** `VelocityMain` runs `runBlocking { onLoad() }` inside its constructor (Guice injection + thread) and declares `@Subscribe suspend fun` handlers — Velocity's event bus does not natively + support suspend listeners; verify the surf-api adapter covers this, or the shutdown hook never runs. +- **L23.** Three different mechanisms for "where is my data directory": Paper `lateinit var` set from + a bootstrapper, Velocity a global `lateinit var plugin`, standalone a `@Volatile` static configured + by a side-channel `configure()`. +- **L24.** `LuaScriptRegistry` loads resources through `EventBusInstance.instance.getResourceAsStream` + — a `requiredService` lookup and the *platform's* classloader, for resources that live in + `surf-eventbus-core`. It works only because they end up in the same jar. + `LuaScriptRegistry::class.java.getResourceAsStream` has neither dependency. +- **L25.** `.gitignore` lists `.idea` twice (line 14 as a directory of specific files, line 49 whole). +- **L26.** `RedisApi` carries `@Suppress("unused")` at class level, masking real dead members. +- **L27.** `EventEnvelope.decodeFromString` includes the entire offending wire text in the exception + message, which is then logged at SEVERE — unbounded, attacker-influenced, potentially PII. +- **L28.** No `equals`/`hashCode` contract test for `PacketChunk`, `AuditReport`, + `ChunkAcceptResult.Complete` — all three hand-write both. + +--- + +## Cross-Cutting Improvements + +### X1. One service-locator abstraction (fixes H9) + +Seven declaration sites, five idioms, three eager. One `internal object Services` with +`required()`/`optional()`, lazy caching, explicit classloader, and a single documented failure +message. Removes ~40 lines and one whole class of startup-order bug. + +### X2. One transport-plumbing abstraction for the two Redis transports (fixes C3) + +`RedisEventTransport` and `RedisQueryTransport` both: call `ensureConnected()`, get a topic, publish +with `awaitFirstOrNull`, add a listener, track it, remove it on disconnect. They disagree on three of +those five — and each disagreement is a bug in the event one. Extract +`RedisChannel(redis, codec)` with `publish(payload)`, `subscribe(handler): ListenerHandle`, and +`ListenerHandle.close()`. + +### X3. One stream-backed structure base (largest duplication in the repo) + +`SimpleRedisCacheImpl` (435 lines) and `SimpleSetRedisCacheImpl` (807 lines) independently +re-implement what `AbstractStreamSyncStructure` (397 lines) already does: `init` → validate codec → +fetch latest stream id → poll continuously → parse `type`/`msg` fields → version gating → resync on +fault → TTL refresh loop → `dispose0`. Method-for-method: +`startPolling`, `handleStreamFault`, `processStreamMessage`, `startRefreshingTtl`, +`clearNearCacheOnly`, and a private sealed `CacheEntry` exist in both caches. + +That is roughly 1,240 lines duplicating 400. Rebasing both caches onto +`AbstractStreamSyncStructure` (or a shared `AbstractStreamBackedStructure` extracted from it) is the +single highest-value refactor available, and it would also give the caches the version-gap resync +logic they currently approximate. + +### X4. One audit-report factory (fixes C4, M9, M10, M23) + +`AuditReports` exists and is good. It is used by `RetryPublisher`, `ReturnListenerBridge` and +`RabbitPacketChunkAssembler`, and **bypassed** by `RabbitListenerHandlerManager` (two hand-built +15-line `AuditReport(...)` blocks), `EventDispatcher` (two more) and `QueryDispatcher` (one more). +Five hand-built reports, and every one of them gets at least one field wrong (M9, M10, M23). +Move `AuditReports` into the api module (it only needs `AMQP.BasicProperties` for one overload — +split that off), give it `eventHandlerFailed`, `queryHandlerFailed`, `unknownEventType`, and make it +the only way to construct an `AuditReport`. + +### X5. One `awaitCondition` test helper + +`FireAndForgetTest`, `RetryIntegrationTest` and `ConsumerDeathTest` each define a private polling +loop (`while (!condition()) delay(…)`). The Redis suites use blind `delay(SETTLE_MILLIS)` instead. +One shared `suspend fun awaitAtMost(timeout, poll, condition)` in `testing/`, used everywhere, +removes both the duplication and most of the flakiness. + +### X6. Precomputed subscription plan (fixes H6) + +`freeze()` should produce an immutable `SubscriptionPlan` — the subscription list, the known-class +set, the loader set, compiled patterns, and an exact-topic index — that `EventDispatcher` reads +without allocating. The registry is already frozen; nothing else needs to change semantically. + +### X7. One Netty transport detection (fixes M3) + +### X8. A `Secret` value class (fixes M7) + +--- + +## Testing Plan + +### Current state + +277 test methods across 73 files. Genuinely strong areas: chunking protocol (`ChunkingTest`, +`ChunkSeriesTest`), topology (`RabbitTopologyDeclarerTest`, `QueueArgumentsTest`), retry +(`RetryPolicyTest`, `RetryQueueTest`, `RetryIntegrationTest`), circuit breaker (including a Lincheck +concurrency test), config layering, KSP validation, and the four container suites. + +Structural problems: + +1. **Nothing runs them.** (C1) +2. **The production Redis wiring is untestable and untested.** `RedisBusSuite`'s own KDoc explains + that `withRedis()` cannot be pointed at a container, so every Redis suite uses the + `withRedis(event, query)` seam. `RedisTransportProviderImpl`, `RedisComponentProviderImpl`, + `redisConfig` and `RedisCredentialsProviderImpl.redisURI()` have zero coverage. Fixing C6 fixes + this. +3. **Blind sleeps.** `delay(SETTLE_MILLIS)` ×10 in `EventSuiteTest`, `delay(5_000)` in + `FireAndForgetTest`, `delay(3_000)` twice, `Thread.sleep(500)` in `QueueOverflowTest`. Slow and + timing-dependent. (X5) +4. **Claimed coverage exceeds actual.** `EventSuiteTest`'s KDoc says *"Spec tests 1–12c"*; tests + 6, 7, 8, 12b and 12c do not exist. +5. **Tests that validate unused code.** `AuditMessageIdentityTest` (`stamp` is production-dead), + `QueryServiceRegistryTest.timeoutOf`, `AuditReportsTest`'s `appId` case (never set in production). + +### Missing tests, by priority + +**Tier 1 — untested production classes on the critical path** + +| Class | Lines | What to test | +|---|---:|---| +| `SimpleSetRedisCacheImpl` | 807 | add/removeById/removeByIndex/removeIf/invalidateAll; index consistency; near-cache expiry per entry kind; Lua flag/touched parsing; concurrent add of the same id; stream fault → resync | +| `SimpleRedisCacheImpl` | 435 | get/put/putNull/invalidate/cachedOrLoad(Nullable); null-marker semantics; TTL refresh gate; stream message parsing incl. malformed | +| `SyncMapImpl` / `SyncListImpl` / `SyncSetImpl` / `SyncValueImpl` | ~800 | local/remote convergence; version gap → resync; own-origin suppression; batch mutation version range; listener notification on remote change only | +| `RabbitPublisher` | 154 | confirm timeout → `SurfRabbitPublishException`; channel reset on failure; `channelOpenAttempts` exhaustion; generation mismatch mid-publish; return listener installed on a *new* channel after reset | +| `RabbitConnectionProvider` | 217 | generation increments on recovery; `awaitOpen` rejects a stale generation; `close()` is idempotent; listeners fire in order; concurrent `connection()` creates exactly one | +| `RabbitConsumer` | 170 | nack-on-handler-error path; `prefetchCount` applied only when `!autoAck`; `onCancelled` invoked; `close()` cancels in-flight processing | +| `RabbitPacketChunkAssembler` | 265 | duplicate chunk delivery; two series on one correlation id; expiry → `CHUNK_SERIES_EXPIRED` audit; `discard` mid-series; concurrent completion (only one `Complete`) | +| `ReturnListenerBridge` | 90 | return before confirm ordering; audit suppression for the audit service itself; `unregister` clears a recorded return | +| `RetryPublisher` | 152 | attempt header increment; expiration dropped; identity header preserved (this is C4's regression test); re-chunking on the retry path | +| `RpcServiceExecutor` | 116 | fire-and-forget rethrows; non-F&F responds with an error; `CancellationException` propagates; unknown callable message | + +**Tier 2 — regression tests for the defects in this document** + +| Test | Guards | +|---|---| +| `suspend @SurfSubscribe is rejected (or invoked)` | C2 | +| `RedisEventTransport removes its listeners on disconnect` | C3 | +| `an event published immediately after connect is delivered` | C3 | +| `the first failure report and the retry stamp share one messageUuid` | C4 | +| `event handler failures reach the configured sink` | C5 | +| `a plugin-local eventbus-plugin.yml overrides redis.host` | C6 | +| `build(environment) overrides the resolved settings` | C8 | +| `fetchRedisOs extracts the full OS string` | C9 | +| `disconnect() disconnects every transport even when the first throws` | H1 | +| `a timed-out handler republishes exactly once` | H4 | +| `freeze() rejects a query service without the Redis transport` | H13 | +| `AMQP_HEADER and sync NAMESPACE constants are unchanged` | M1 (wire compat) | + +**Tier 3 — thin but valuable** + +`RabbitMqVersion` (parse/compare/`fromHeaders` edge cases — currently untested despite being wire +protocol), `EventTypeResolver` (registry hit, classloader hit, negative caching, non-`SurfBusEvent` +class rejected), `BusEventCodecs` (companion detection, absence caching), `KotlinSerializerCache` / +`KotlinSerializerNameCache`, `ParametersSerializer` (optional omission, missing required field, +contextual/`@Serializable(with=)` annotations preserved), `RabbitPacketSerializer` (round trip, +unknown class name, corrupt frame), `MessageKind` (exists), `RedisChannels` (exists), +`LuaScriptRegistry` (missing resource message), `DisposableAware` (double dispose, track-after-dispose). + +**Tier 4 — properties worth property-based testing** + +`EventTopics.matches` against a reference AMQP implementation or a generated corpus (the recursive +`#` handling is the subtlest logic in the repo and has one unit test file); +`RabbitPacketChunking.split → decode → assemble` round-trip over random sizes including exact +multiples of the chunk size; `RabbitTopology.sanitize` idempotence (documented, untested). + +**I have not written these test files.** The audit itself was the requested deliverable and writing +~35 production-quality test classes is a substantial separate piece of work — several of them +(the cache and sync suites) need container fixtures that do not exist yet. Say the word and I will +work through them in the tier order above, starting with the Tier 2 regression tests, which are small +and pin the defects before the fixes land. + +--- + +## Architecture Roadmap + +In dependency order. Each stage is independently shippable. + +**Stage 0 — make the work verifiable (blocks everything)** +CI on pull requests running `./gradlew check` with Docker; fail on skipped integration tests. +Add Detekt + Ktlint (or Spotless) with a baseline, so the ~60 mechanical findings in "Low Priority" +are enforced rather than re-audited. + +**Stage 1 — stop the silent failures (C2–C5, C8–C10, H1, H4)** +Small, independent, high-value fixes. Each gets a Tier-2 regression test first. + +**Stage 2 — one configuration path (C6)** +Delete `redisConfig`; resolve `EventBusSettings` once in `SurfEventBusBuilderImpl` and pass +`RedisSettings` into the Redis SPI. Unlocks testing the production Redis wiring, fixes the layering +bug, and removes the last process-wide mutable singleton. + +**Stage 3 — one of each shared concern (X1, X4, X7, X8, H10, H11, H12)** +Service locator, audit factory, Netty detection, `Secret`, descriptor lookup, exception hierarchy, +exception files. Mostly mechanical, large consistency payoff, low risk. + +**Stage 4 — decompose the two god classes (M13, M19)** +`RabbitConnectionImpl` → `RpcCaller` + `RpcResponder` + `ReplyChannel`. +`RedisApi` → `RedisConnection` (lifecycle) + `RedisStructures` (factories) + `RedisDiagnostics`. +Do this after Stage 3 so the extracted pieces use the unified helpers. + +**Stage 5 — one concurrency model at the boundary (M18, C7)** +Make Reactor internal: `Initializable`, `SyncStructure`, `SimpleRedisCache`, `SimpleSetRedisCache` +become `suspend`-based. Then remove Redisson/Netty/Reactor from the public ABI and re-dump +`surf-eventbus-api.api`. This is the breaking change that should land *in* 2.0, not after it. + +**Stage 6 — collapse the duplicated stream machinery (X3)** +Rebase both caches onto the shared stream-backed base. Largest single reduction in the repo +(~800 lines), but it must come after Stage 5 or it will be redone. + +**Stage 7 — performance (H5, H6, X6, M4)** +Async publisher confirms, precomputed subscription plan, configurable and shared thread pools. +Use the existing JMH harness (`EventTransportBenchmark`, `codecBenchmark`) to measure before and +after; extend it with a publish-throughput benchmark, which does not exist. + +--- + +## Refactoring Plan (executable, ordered to minimise conflicts) + +Ordering rule: mechanical/global changes before structural ones; file moves last within a stage. + +### Step 1 — CI and tooling +1. Add `.github/workflows/ci.yml`: `pull_request` + `push`, JDK from the toolchain, `./gradlew check + --stacktrace`, Docker available. Cache Gradle. +2. Add `-PrequireIntegration` and make `DockerAvailableCondition` *fail* rather than skip when it is + set; pass it on CI. +3. Add Detekt and Ktlint with a generated baseline; add `detekt` and `ktlintCheck` to `check`. +4. Add a `docker-compose.yml` (rabbitmq:management + redis) and a `docs/development.md` describing + the local loop. Neither exists today. + +### Step 2 — regression tests for the known defects +Write the Tier-2 tests listed above. They must fail against `HEAD`. + +### Step 3 — silent-failure fixes (one commit each, each referencing its test) +1. `EventSubscriptionRegistry` — reject suspend handlers with a message naming the method (C2). +2. `RedisEventTransport` — `awaitSingle()` the listener ids, track `(topic, id)`, `removeListener` + on disconnect (C3). +3. `AuditReports.base` — take `messageUuid` as a parameter; `RetryPublisher` resolves it once and + uses `AuditMessageIdentity.stamp` (C4). +4. `SurfEventBusImpl` — accept an `AuditSink` constructor parameter; `SurfEventBusBuilderImpl` passes + `rabbitApi?.connection?.auditSink ?: LoggingAuditSink` (C5). +5. `SurfEventBusBuilderImpl.build` — pass `environment` into config resolution (C8). +6. `RedisApi.fetchRedisOs` — fix the Lua escaping (C9). +7. `RabbitConnectionProvider` — `withContext(Dispatchers.IO)` around `newConnection`, `Mutex` + instead of `synchronized` (C10). +8. `SurfEventBusImpl.disconnect` — `runCatching` each step, rethrow first with suppressed (H1). +9. `RabbitListenerHandlerManager` — single settle path for retry/dead-letter (H4). +10. `RabbitAuditSink` — implement `AutoCloseable`; close it from `RabbitConnectionImpl.disconnect` + (H2). +11. `EventTypeResolver`, `EventDispatcher.warnedTypes`, `QueryDispatcher.DescriptorCache` — bounded + Caffeine caches (H3). +12. `SurfEventBusImpl.freeze` — symmetric transport checks for queries and RPC (H13). +13. `SurfRabbitApi.frozen` — `AtomicBoolean` (H14). + +### Step 4 — configuration unification (C6) +1. Add `RedisSettings` parameters to `RedisComponentProvider.createRedissonConfig` and + `RedisCredentialsProvider.redisURI(settings)`. +2. `SurfEventBusBuilderImpl` resolves `EventBusSettings` once (global from the platform path, plugin + from the builder's path) and passes both halves down. +3. Delete `RedisConfigAccess.kt`. +4. Rewrite the Redis suites to use the production `withRedis()` path; keep `withRedis(event, query)` + only for the fake-transport unit tests. + +### Step 5 — shared abstractions (mechanical, large diff, low risk) +1. `internal object Services` + replace all seven lookup sites; delete the `INSTANCE` duplicates + (X1/H9). +2. `internal object ServiceDescriptors` + replace all three descriptor caches; share the + `"…Descriptor"` suffix constant with the KSP module (X4/H10). +3. `NettyTransports` + delete `TransportInfo` and `RabbitClient.NettyTransport` (X7/M3). +4. `Secret` value class + delete the five `toString` overrides (X8/M7). +5. Move `AuditReports` to the api module; add `eventHandlerFailed`/`queryHandlerFailed`/ + `unknownEventType`; replace the five hand-built reports; set `appId`/`type`/`contentEncoding`/ + `x-surf-instance` in `RabbitConnectionImpl.properties()` (X4/M9/M10/M23). +6. Exception hierarchy: re-parent the four strays; regroup the five exception files by what they + contain (H11/H12). +7. Delete the confirmed dead code in L4; delete `nackIfUnsettled`/`reject` (M15); collapse + `RetryPolicy`'s ladder onto `RetryTier.entries` and delete the `retryEnabled` flag chain (M16). + +### Step 6 — naming (do it while 2.0 is already breaking) +1. `RabbitMqVersion` → `RabbitMQVersion`; `ServiceTypeKrpc` → `ServiceTypeWithSerializers`. +2. `RedisApi` → `SurfRedisApi` (or drop the prefix from both — decide once). +3. Wire constants: `x-surf-rabbitmq-version` → `x-surf-eventbus-version`; + `surf-redis:sync:` → `surf.eventbus.sync:`. Add the constant-pinning test *and* a rollout note — + both are breaking on the wire. +4. `ServiceDefaults.kt` → `ServiceImplementations.kt`; move `QueryFrame` out of `QueryTransport.kt`; + move `RabbitConnectionGenerationChangedException` into `ConnectionExceptions.kt`. +5. Fix the stale user-facing strings in `RabbitClient` (`RabbitMQApi.disconnect()`). + +### Step 7 — documentation +1. Rewrite `RpcService`'s KDoc against the current API; add a compiled `samples/` source set so it + cannot rot again (H8). +2. Rewrite `surf-eventbus-ksp/README.md` for both annotations. +3. Rewrite `RedisApi`'s class KDoc; delete the `@Deprecated(ERROR)` overload. +4. Reconcile the README audit table with `AuditKind` (M11); document the fifth config layer + (`surf.rabbitmq.outgoing*ChunkingEnabled` system properties in `EventBusConfigResolver:89-103`) + or delete it — the README says four layers and there are five, with pre-2.0 names. +5. Fix the stale module names in KDoc (`surf-eventbus-bus-core`, `surf-eventbus-redis-core`, + `surf-eventbus-rabbitmq-api`) and the broken `[RedisTransportProvider]` link in + `SurfEventBusFactory`. + +### Step 8 — decomposition, then Reactor removal, then the cache merge +Stages 4–6 of the roadmap. Each needs its own design pass; do not start before Steps 1–3 are merged. + +--- + +## File-by-File Review + +Reviewed individually below: all Kotlin and Java sources (≈200 files), build scripts, CI and prose +docs. The 21 Lua scripts under `surf-eventbus-core/src/main/resources/lua/` are covered as one entry +(they share one set of issues), as are the 14 planning documents under `docs/superpowers/` and the +Gradle wrapper. Files with nothing to say beyond "fine as is" are grouped. + +### Root and build + +| File | Purpose | Findings | +|---|---|---| +| `build.gradle.kts` | Root config, shadow relocation, Netty native-name mangling | Relocation + `api(redisson)` + public Redisson types = C7. The `doLast` zip-rewriting block (lines 59-107) is 50 lines of untested build logic with a silent `if (!jar.exists()) return`; extract to a `buildSrc` task with a test. `version` read via `findProperty as String` will NPE-cast if absent. `optIn` applied to every subproject means consumers of the *build* also opt in silently. | +| `settings.gradle.kts` | Module includes | Fine. Consider `includeBuild` for `buildSrc` once the shadow logic moves. | +| `gradle.properties` | `version=2.0.0`, `kotlin.stdlib.default.dependency=false` | No `org.gradle.caching`, no `org.gradle.configuration-cache`, no JVM args. Build performance is unconfigured. | +| `gradle/libs.versions.toml` | Version catalog | Good, but partial: kotlinpoet (2.3.0), buildconfig (6.0.9 in core, **6.0.10** in api — two versions of one plugin), kctfork, fastutil, kotlinx-serialization (1.11.0, declared five times as a string), velocity-api, surf-api (`+`), mccoroutine are all outside it. `surf-microservice = "2.+"` and `surf-api:+` are dynamic versions — non-reproducible builds. | +| `surf-eventbus-api/build.gradle.kts` | api module | `api(libs.redisson)` (C7). Two long comments explain test-classpath workarounds — legitimate, but they describe a fragile setup. `failOnNoDiscoveredTests = false` hides an empty test run. | +| `surf-eventbus-core/build.gradle.kts` | core module | 174 lines; the eight `runtimeOnly` native-classifier blocks are copy-paste (loop over a list). `@Suppress("RedundantSuppression", "AvoidDuplicateDependencies")` at the top. `afterEvaluate { configurations.named("jmhRuntimeClasspath") { setExtendsFrom(…) } }` is a fragile classpath hack. JMH `failOnError = true` with a smoke mode is good. | +| `surf-eventbus-ksp/build.gradle.kts` | processor | `dev.zacsweers.kctfork:ksp:+` — dynamic version on a test dependency. Depends on **both** api and core for tests (core only for fixtures?) — check whether the core dependency is needed. | +| `surf-eventbus-platform/*/build.gradle.kts` | three plugins | Paper and Velocity are three lines each — good. Standalone declares its own publication block while the other two rely on convention plugins; inconsistent. | +| `.github/workflows/publish.yml` | release | C1: this is the *only* workflow. Also publishes only the paper and velocity jars, while api/core/standalone declare publications. | +| `.gitignore` | — | `.idea` listed twice (L25). | +| `gradlew`, `gradlew.bat`, `gradle/wrapper/*` | wrapper | Standard; wrapper jar is committed as intended. | + +### `surf-eventbus-api` — root package + +| File | Purpose | Findings | +|---|---|---| +| `SurfEventBus.kt` | The public entry point | Good shape and good KDoc. Stale module name `surf-eventbus-bus-core`. `registerService` takes `KClass` with a reified extension — consistent. The `subscribe()` reified overload requires a Kotlin `object` and `error()`s otherwise; a compile-time constraint would be better but there is no way to express it. `connect()`/`disconnect()` have no KDoc while everything around them does. | +| `SurfEventBusBuilder.kt` | Builder contract | C8 (ignored `environment`). `withRedis(event, query)` is a test seam in the *public* API — mark `@InternalEventBusApi` or move it behind a testing artifact. Stale module name. | +| `SurfEventBusFactory.kt` | SPI | KDoc references `[RedisTransportProvider]`, which lives in core and does not resolve. Stale module names ×3. | +| `InternalEventBusApi.kt` | Opt-in marker | Good. Missing `AnnotationTarget.PROPERTY_GETTER` and `VALUE_PARAMETER`, both used elsewhere in the project. | + +### `surf-eventbus-api` — `config` + +| File | Findings | +|---|---| +| `EventBusConfig.kt` | Excellent KDoc. Two hand-written `toString` overrides (M7). 14 + 4 fields with `@JvmField` — fine for Configurate. `serverPrefetchCount` max is `Short.MAX_VALUE` while AMQP allows unsigned short; harmless. | +| `EventBusConfigResolver.kt` | The four-layer resolution is clear and correct for Rabbit. **Undocumented fifth layer**: `systemBoolean("surf.rabbitmq.outgoingRequestChunkingEnabled")` (lines 89-103) — pre-2.0 property names, contradicting both the README ("four layers") and the rollout doc's rename table. The two chunking fields are the only ones with it. Decide: document or delete. Repetition of `?: yaml(...) ?: default` 18 times invites a small `layered(env, plugin, global, default)` helper. | +| `EventBusConfigFiles.kt` | Good, and its KDoc states the rule Redis breaks (C6). `globalCache` is unbounded and keyed by `(Path, String)` — fine in practice. `plugin()` is deliberately uncached; note the asymmetry in the KDoc. | +| `EventBusSettings.kt` | M6 (non-deterministic default), M7 (two `toString`s). `EventBusDefaults` is the right idea; `redisClientName()` being a function among constants is the tell for M6. | + +### `surf-eventbus-api` — `event`, `transport` + +| File | Findings | +|---|---| +| `BusEvent.kt` | Clean. No validation that the topic is wildcard-free at the annotation level (checked at runtime in `EventTopics`); a KSP check would move it to compile time. | +| `BusEventCodec.kt` | Clean, good example. Exposes `io.netty.buffer.ByteBuf` in the public ABI (C7). | +| `EventTopics.kt` | The recursion in `matches` allocates a new list per segment via `drop()`; called per subscription per event (H6). `segmentPattern` is recompiled per call via `matches` on each segment — actually compiled once, fine. Consider a compiled-pattern type. Good validation and good KDoc. | +| `SurfBusEvent.kt` | Two public `var`s with `@InternalEventBusApi set` — the mutation is a dispatcher concern leaking into the user-facing base type. The values are also carried by `EventEnvelope`, so they are on the wire twice for JSON events (the abstract class is `@Serializable`). Consider making the base type immutable and passing metadata to the handler separately. | +| `SurfSubscribe.kt` | Clean; the `includeSelf` rationale is the best comment in the repo. | +| `EventEnvelope.kt` | L27 (raw text in the exception). `encodeToString(json)` taking `Json` as a parameter on an instance method is slightly awkward; a `EventEnvelopeCodec` would be cleaner. | +| `EventTransport.kt` | Redundant self-import (L1). Good KDoc. The `onEvent: suspend (EventEnvelope, ByteArray?) -> Unit` signature encodes "binary or JSON" as a nullable second parameter — a sealed `EventPayload` would be clearer. | +| `QueryTransport.kt` | Declares `QueryFrame` (M2). Typo in `answer`'s KDoc: *"Called only when the handler abstained not."* | + +### `surf-eventbus-api` — `service`, `query` + +| File | Findings | +|---|---| +| `ServiceDescriptor.kt` | `getCallable` duplicates `callables[…]` (L5). | +| `ServiceCallable.kt` | `Array` (L6). | +| `ServiceDefaults.kt` | M2 (name), `ServiceTypeKrpc` (M1). Four public classes with no `equals` — used as `ConcurrentHashMap` keys in `ServiceSerializerCache`, relying on identity; document that. | +| `ServiceInvoker.kt`, `ServiceParameter.kt`, `ServiceType.kt` | Clean. `ServiceType`'s KDoc is a good example of explaining *why*. | +| `query/QueryService.kt` | KDoc references "plan 3" — an internal planning document leaking into the public API surface. The `null = abstain` contract is well explained. | +| `query/descriptor/QueryServiceDescriptor.kt` | Clean. `createInstance(instanceId, json, transport)` takes three unrelated parameters that could be one `QueryContext`. | + +### `surf-eventbus-api` — `rabbitmq` + +| File | Findings | +|---|---| +| `SurfRabbitApi.kt` | H14 (unsynchronised `frozen`, one-shot scope). The class exists in parallel with `SurfEventBus` as a second public entry point with its own builder and its own config resolution — the README does not mention it. Decide whether it is public API or an internal detail of `SurfEventBus`; if public, it needs the same treatment (audit sink injection, transport checks); if not, mark it internal. `createCbor` in a companion is fine. | +| `SurfRabbitApiBuilder.kt` | Duplicates `SurfEventBusBuilderImpl`'s job. `resolveConfig` is the *correct* per-plugin layering that Redis lacks (C6) — this is the code to copy. `configFileName` override exists here and nowhere else. | +| `connection/RabbitMQConnection.kt` | Nested `@InternalEventBusApi companion` inside an already-internal interface — redundant. | +| `connection/RabbitMQConnectionFactory.kt` | H9 (eager class-init lookup, duplicate `INSTANCE`). | +| `identity/RabbitIdentity.kt` | L7 (should be a data class). The random-suffix logic (`nextInt().toLong().and(0xFFFFFFFF)`) is a roundabout way to get 8 hex chars; `Integer.toHexString` reads better. | +| `target/RabbitTarget.kt` | Clean sealed interface, good KDoc. KDoc references `[RabbitIdentity.instanceId]` without importing it — unresolved link. | +| `version/RabbitMqVersion.kt` | M1 (casing, `x-surf-rabbitmq-version`). KDoc says "surf-rabbitmq library" throughout. `isNewerThan`/`isOlderThan`/`isAtLeast`/`isAtMost` are four wrappers over `Comparable` — keep `isAtLeast(major, minor, patch)`, drop the rest. No tests despite being wire protocol (Tier 3). | +| `packet/RabbitPacket.kt` | Unused `timestamp` on every packet (M14). | +| `packet/RabbitRequestPacket.kt` | M14 (DTO + `CoroutineScope` + response channel). | +| `packet/RabbitResponsePacket.kt` | Empty marker; fine. | +| `rpc/FireAndForget.kt` | Excellent KDoc. | +| `rpc/RabbitRpcCall.kt` | `Array` arguments; fine for the generated path. | +| `rpc/RabbitRpcService.kt` | `unregisterService` is dead (L4) and contradicts the freeze model. | +| `rpc/RabbitRpcServiceFactory.kt` | H9 (eager `val instance` in a companion — the fifth idiom). | +| `rpc/RpcService.kt` | H8 — 100 lines of KDoc for an API that no longer exists. | +| `rpc/descriptor/RpcServiceDescriptor.kt` | Clean. | +| `exception/*.kt` (8 files) | H11, H12, L4. `ApiExceptions.kt` and `ProtocolExceptions.kt` hold one class each, misfiled. | + +### `surf-eventbus-api` — `redis` + +| File | Findings | +|---|---| +| `RedisApi.kt` | M19 (god class, stale KDoc, overload explosion, weak-key lifecycle registry, `lateinit` public), C7, C9. The single most-improvable file in the repo. | +| `RedisComponentProvider.kt` | 12-method SPI mixing thread pools, config, plugin-name extraction and six structure factories — ISP violation. H9. Split into `RedisRuntimeProvider`, `RedisStructureFactory`, `RedisConfigFactory`. | +| `RedisExceptions.kt` | One abstract class in a plural-named file (M2); nothing extends it — `SurfRedisException` has zero subclasses, so the Redis half still throws bare `IllegalStateException`/`IllegalArgumentException` (H11). | +| `internal/RedissonConfigDetails.kt` | `serializerModule` is never read (M5). | +| `cache/SimpleRedisCache.kt`, `cache/SimpleSetRedisCache.kt` | Public interfaces extending `reactor.core.Disposable` (C7, M18). `SimpleSetRedisCache` has 12 methods including four `…OrLoad`/`…OrLoadNullable` variants — the nullable/non-nullable × by-id/by-index cross-product; a single `find(spec, loader): T?` would collapse them. | +| `cache/RedisSetIndexes.kt` | Reasonable. | +| `codec/RedisCodec.kt` | Good contract, well documented. `codecId get() = javaClass.name` is a sensible default but ties the wire identity to the class name — the KDoc says so. | +| `codec/AbstractCodec.kt` | Extends `org.redisson.client.codec.BaseCodec` in the public ABI (C7). | +| `codec/ByteBufExtensions.kt` | 454 lines of extension functions — the largest utility file. Needs a table of contents in the KDoc, or splitting by type (`ByteBufPrimitives`, `ByteBufCollections`, `ByteBufOptional`). Partially tested via `AbstractCodecTest`/`RedisUtf8StringTest`. | +| `codec/CodecExtensions.kt`, `codec/RedisUtf8String.kt`, `codec/RedisCodecException.kt` | Fine. | +| `codec/JsonKotlinCodec.kt` | Fine. | +| `codec/default/*.kt` (7 files) | Uniform 14-16 line codecs; good. `VarIntBinaryCodec`/`VarLongBinaryCodec` duplicate the Java `RedisVarInt`/`RedisVarLong` logic across languages. | +| `java/…/RedisVarInt.java`, `RedisVarLong.java`, `UUIDCodec.java` | The only Java in the project (three files, 202 lines), presumably for hot-path reasons that are not documented. Either document why they are Java or convert them — Kotlin compiles to the same bytecode for this. | +| `sync/SyncStructure.kt` | Reactor in the public ABI (C7, M18). Good KDoc. | +| `sync/{list,map,set,value}/Sync*.kt`, `Sync*Change.kt` (8 files) | Consistent shape, good. `Sync*Change` types are a nice sealed model. | +| `util/Initializable.kt` | `Mono` in the public ABI (C7). | +| `util/RedisUtils.kt` | M18 (hand-rolled `Subscriber`, spec violation, duplicate of the library function). | +| `credentials/CredentialsProvider.kt` | An empty marker interface whose KDoc explains a symmetry that the two sub-interfaces then break (one returns a plain data class, the other a Redisson type). | +| `credentials/RabbitCredentialsProvider.kt` | Not marked `@InternalEventBusApi` while its Redis twin is. M7 (`toString`). | +| `credentials/RedisCredentialsProvider.kt` | Returns `org.redisson.misc.RedisURI` (C7), contradicting the design principle stated in its twin's KDoc. H9. | +| `platform/EventBusInstance.kt` | `orNull()` re-scans `ServiceLoader` on every call (H9). Default `getResourceAsStream` delegating to `javaClass` is subtle — it resolves against the *implementation's* classloader (L24). | +| `platform/StandaloneLifecycleHook.kt` | Good — the only lookup that handles absence correctly. | +| `platform/JavaPluginLoaderProxy.kt`, `SerializedPluginDescriptionProxy.kt` | Paper-internal reflection proxies sitting in the transport-neutral api module with no KDoc explaining what they are for or when they run. Three references each. Document or move to the Paper module. | +| `audit/AuditReport.kt` | M8 (partial `equals`), `terminal = true` default is dangerous. | +| `audit/AuditKind.kt` | M11 (README drift). | +| `audit/AuditService.kt` | An `audit`-package type importing `rabbitmq.rpc` annotations — the "transport-free" claim in `AuditReport`'s KDoc does not extend to the service. | +| `audit/AuditSink.kt` | Contract says "must never throw"; nothing enforces it and `LoggingAuditSink` is the only implementation that honours it structurally. | +| `circuitbreaker/CircuitBreaker.kt` | Well built and well tested (including Lincheck). `refreshState` needs `java.time.Duration` fully qualified because of the `kotlin.time` import — use an import alias. Belongs in a shared utility module rather than the bus's public API. | +| `circuitbreaker/CircuitBreakerRegistry.kt` | `names()`/`resetAll()` are dead (L4). No eviction: a process calling `rpc(InstanceTarget(id))` with many ids grows the map unboundedly. | +| `circuitbreaker/CircuitState.kt`, `CircuitOpenException.kt` | Fine; the exception is outside the hierarchy (H11). | +| `serialization/KotlinSerializerCache.kt` | Good use of `ClassValue`. Four instances exist across the codebase (L16). | + +### `surf-eventbus-core` + +| File | Findings | +|---|---| +| `core/SurfEventBusImpl.kt` | C2 (via the dispatcher), C5, H1, H13, `!!` at line 148, unused `dataPath`, third descriptor cache (H10). Otherwise the clearest class in the repo — the `require*` error messages are a model for the rest. | +| `core/SurfEventBusBuilderImpl.kt` | C8. `withRedis()` eagerly resolves three SPI objects at builder time, before `build()`; a failure surfaces at the wrong place. | +| `core/SurfEventBusFactoryImpl.kt` | Fine. | +| `core/RedisTransportLocator.kt` | Stale module name. Declares `RedisTransportProvider` in the same file (M2) — and that interface is what `SurfEventBusFactory`'s KDoc tries to link to from another module. | +| `core/audit/LoggingAuditSink.kt` | Fine; nine positional `%s` in one log line is at the limit of readability. | +| `core/dispatch/EventDispatcher.kt` | C2, H3, H6, M10, X4. The `warnedTypes` "warn once" mechanism duplicates `EventTypeResolver`'s negative cache (L4). | +| `core/dispatch/QueryDispatcher.kt` | H3, H10, M23, X4. `Class.forName` outside the `try` in `DescriptorCache` (H10). | +| `core/dispatch/BusEventCodecs.kt` | Neat. `getDeclaredField("Companion").isAccessible = true` will hit module access restrictions on a JPMS classpath; catch `InaccessibleObjectException` too. | +| `core/dispatch/EventTypeResolver.kt` | H3. The `SurfBusEvent` assignability guard before caching is a genuinely good security decision, and the comment says so. `isKnownUnresolvable` is dead. | +| `core/registry/EventSubscription.kt` | German KDoc (L3). | +| `core/registry/EventSubscriptionRegistry.kt` | C2, L12, L13. `trySetAccessible` with the explanatory comment is excellent. | +| `core/registry/QueryServiceRegistry.kt` | `timeoutOf` is production-dead (L4). Otherwise clean. | +| `platform/EventBusPlatformInstance.kt` | L21 (empty `onEnable`). Correctly uses `NonCancellable` on shutdown. | +| `rabbitmq/connection/RabbitConnectionImpl.kt` | C10 (indirect), H2, M12, M13, L1, L4. The single most complex file; the comments are good enough that the complexity is *legible*, which is why decomposition is safe. | +| `rabbitmq/connection/RabbitClient.kt` | M4 (hardcoded 8 + 16 threads in a static initialiser), M20 (10 s sleep), M1 (stale `RabbitMQApi` in user-facing text), M3. `activeClients` retains clients strongly for leak reporting — the leak detector prevents the collection it detects. | +| `rabbitmq/connection/RabbitConnectionProvider.kt` | C10. Declares an exception (M2). Otherwise a careful, correct state machine. | +| `rabbitmq/connection/ReturnListenerBridge.kt` | Unbounded `scope.launch` per returned message — a routing outage becomes a coroutine storm. The self-audit guard (`routingKey != auditServiceName`) is a good catch. | +| `rabbitmq/connection/RabbitConnectionListener.kt`, `RabbitConnectionSnapshot.kt`, `RabbitConnectionStatus.kt`, `RabbitClientHealthSnapshot.kt` | Small and clean. | +| `rabbitmq/connection/RabbitConnectionFactoryImpl.kt` | Fine. | +| `rabbitmq/consumer/RabbitConsumer.kt` | M4 (a thread per consumer; the `declare` consumer is never released). `getChannel` is `suspend` and blocks transitively (C10). | +| `rabbitmq/consumer/RabbitAck.kt` | M15 (duplicate methods, dead `reject`). | +| `rabbitmq/consumer/RabbitListenerHandlerManager.kt` | H4, X4 (two hand-built reports), `retryEnabledFor` ignores its parameter (M16), `(api.rpcService as RabbitRpcServiceImpl)` breaks its own abstraction. The nested try/catch/`invokeOnCompletion`/`AtomicReference` control flow is the hardest code in the repo to verify; `runCatching { handlerJob.join() }` expresses most of it. | +| `rabbitmq/publisher/RabbitPublisher.kt` | H5. `channel` is a non-volatile `var` confined to the dispatcher thread — correct but undocumented; add a comment or `@GuardedBy`. | +| `rabbitmq/publisher/RabbitPublisherPool.kt` | L10 (thread naming). Round-robin via `getAndIncrement` can overflow — `floorMod` handles it correctly; good. | +| `rabbitmq/publisher/MessageKind.kt` | Well designed, well documented, tested. | +| `rabbitmq/publisher/RabbitPublisherOptions.kt` | Not reachable from configuration — `RabbitClient.create` takes a default and nothing overrides it. Either expose it or inline the constants. | +| `rabbitmq/packet/RabbitPacketChunking.kt` | M21 (`decodeOrNull` throws), M22 (duplicated header size). The metadata validation against remote input is thorough and correct — the best security work in the repo. | +| `rabbitmq/packet/RabbitPacketChunkAssembler.kt` | L18, L19. The lock-free `PartialPacket` is correct and well commented. Opportunistic cleanup means a stalled series survives until the next `accept`. | +| `rabbitmq/packet/RabbitPacketSerializer.kt` | `readRemainingBytes` copies the payload on every deserialisation; decoding from the `ByteBuf` slice would avoid it. `buf.array()` assumes a zero-offset heap buffer — true here, fragile. L1. | +| `rabbitmq/packet/RabbitPacketPropertiesInjector.kt` | A 10-line object that mutates two fields on a wire packet (M14). Disappears if `RabbitRequestPacket` is split. | +| `rabbitmq/rpc/RabbitRpcServiceImpl.kt` | H10, L15, L14, L1. `serviceIdCounter`/`callCounter` are per-instance `AtomicLong`s whose values go on the wire — document their scope. | +| `rabbitmq/rpc/RpcServiceExecutor.kt` | M17 (different logger), L16. The `fireAndForget` rethrow path and its comment are correct and subtle. | +| `rabbitmq/rpc/BreakerGuardedRpc.kt` | Very good — the `isTransportFailure` KDoc explaining why `SurfRabbitRequestTimeoutException` is deliberately excluded is exemplary. Well tested. | +| `rabbitmq/rpc/RpcErrorResponses.kt` | Fine; version-gated legacy support is clean. | +| `rabbitmq/rpc/RabbitRpcServiceFactoryImpl.kt` | L1 (two self-imports in a 13-line file). | +| `rabbitmq/rpc/exception/SerializedException.kt` | 199 lines reconstructing exceptions from the wire. Not reviewed line-by-line for this audit beyond confirming it is only reachable from the RPC error path; **it deserves its own security review** — it is remote-input-driven exception construction, and the class-name → `Throwable` path is exactly where deserialization gadgets live. Add it to the test plan (Tier 1). | +| `rabbitmq/rpc/packet/RpcCallRequestPacket.kt`, `RpcCallResponsePacket.kt` | Clean sealed response model. | +| `rabbitmq/topology/RabbitTopology.kt` | Good. `sanitize` idempotence is documented and untested (Tier 4). | +| `rabbitmq/topology/RabbitTopologyDeclarer.kt` | Excellent KDoc — the `406` explanation and the "no alternate exchange" rationale are the kind of comment that prevents a regression. L11. | +| `rabbitmq/topology/QueueArguments.kt` | Good. `MAX_QUEUE_BYTES` (256 MiB) is not configurable; on a shared broker an operator will want it to be. | +| `rabbitmq/retry/RetryPolicy.kt` | M16. The `x-death` investigation write-up is the best comment in the repo. | +| `rabbitmq/retry/RetryPublisher.kt` | C4, L20. | +| `rabbitmq/audit/AuditReports.kt` | M9, X4. Good design, wrong home (core, should be api). | +| `rabbitmq/audit/RabbitAuditSink.kt` | H2. The flood control and self-audit suppression are well reasoned. `enabled` is a dead parameter. | +| `rabbitmq/audit/AuditMessageIdentity.kt` | C4; `stamp` is production-dead (L4). | +| `rabbitmq/health/RabbitMQMicroserviceHealthContributor.kt` | Fine. No Redis equivalent — an operator gets half a health picture. | +| `rabbitmq/credentials/RabbitCredentialsProviderImpl.kt` | Fine. | +| `redis/RedisRuntime.kt` | M4 (16 Netty threads + 8 + 2 schedulers, none configurable). The context-classloader swap in `init` is a real Redisson workaround and is well commented. | +| `redis/TransportInfo.kt` | M3, `data class` over a factory (M3 note). | +| `redis/RedisComponentProviderImpl.kt` | M5 (hardcoded Redisson tuning, unused `serializerModule`). `clientId` derived from the first two UUID segments is 16 hex chars of entropy — fine, but it is the `origin` field in every sync stream message, so document the collision domain. | +| `redis/config/RedisConfigAccess.kt` | C6 — the file to delete. | +| `redis/credentials/RedisCredentialsProviderImpl.kt` | The colon-prefix comment documents a real, previously-shipped bug — good. The password ends up inside a `RedisURI` whose `toString` is not ours (M7). No username/ACL support. | +| `redis/bus/RedisEventTransport.kt` | C3, L4 (`log`), X2. | +| `redis/bus/RedisQueryTransport.kt` | Correct where the event transport is not. Decodes JSON on the Redisson listener thread in `subscribeReply` while `subscribeQuery` launches into a scope — inconsistent. | +| `redis/bus/RedisChannels.kt` | Good, tested; the "why two families" KDoc is exactly right. | +| `redis/bus/BinaryFrame.kt` | `String(header)` uses the platform default charset — should be `Charsets.UTF_8` (it round-trips with `toByteArray()`, which is also platform-default; both are wrong together, so it works until two processes have different defaults). **Fix this**: it is a latent cross-platform wire bug. | +| `redis/bus/RedisTransportProviderImpl.kt` | Eagerly constructs `RedisApi.create()` at `ServiceLoader` instantiation, so `getCallingPluginName()` attributes the connection to the wrong class (M19). `ensureConnected` freezes the api implicitly. | +| `redis/sync/AbstractSyncStructure.kt` | `.block()` on dispose (M18). `NAMESPACE = "surf-redis:sync:"` (M1). | +| `redis/sync/AbstractStreamSyncStructure.kt` | H7 (fire-and-forget writes), X3. 397 lines, six responsibilities. The hand-rolled `parseVersion` and delimiter scanning are optimisations without a benchmark behind them; `StreamEventData.payload(index)` is O(n·index). Inconsistent malformed-message handling (log-and-return vs throw). | +| `redis/sync/SyncValueCodec.kt` | Base64 over a `StringCodec` stream costs 33% on the wire; a `ByteArrayCodec` stream would avoid it. Bounds checks are good. | +| `redis/sync/{list,map,set,value}/Sync*Impl.kt` | Consistent, readable, entirely untested (Tier 1). All inherit H7. | +| `redis/cache/SimpleRedisCacheImpl.kt`, `SimpleSetRedisCacheImpl.kt` | X3 — 1,242 lines duplicating `AbstractStreamSyncStructure`'s machinery. Untested. `SimpleSetRedisCacheImpl` at 807 lines with 20 public methods is the largest class in the repo. | +| `redis/cache/SimpleSetRedisCacheLuaScripts.kt` | 448 lines of Lua in Kotlin string constants — no syntax highlighting, no linting, no tests, and it duplicates the `resources/lua/` approach used everywhere else. Move these to `.lua` resources for consistency (the loader already exists). | +| `redis/util/DisposableAware.kt` | Correct; the post-add re-check is subtle enough to deserve its comment. | +| `redis/util/LuaScriptExecutor.kt` | `NOSCRIPT` retry handling is good. Nested weak Caffeine caches keyed by `RedisApi` and `LuaScriptRegistry` — clever, and the KDoc is longer than the code; a plain field on `RedisApi` would be simpler. | +| `redis/util/LuaScriptRegistry.kt` | L24 (platform-classloader resource loading). | +| `redis/util/RedisExpirableUtils.kt` | `.repeat().subscribe()` — an unkillable refresh loop per structure unless the `Disposable` is tracked (it is). Fine. | +| `redis/util/RedisStreamsUtils.kt` | `Result.handler()` as a callback shape is unusual but readable. 250 ms polling per structure per process — with many structures this is a lot of Redis traffic; note it. | +| `serialization/KotlinSerializerNameCache.kt` | Fine; merge with `KotlinSerializerCache` (L16). | +| `service/serialization/ServiceSerializerCache.kt` | L16 (one per component). | +| `service/serialization/ParametersSerializer.kt` | L17 (shared serial name). The optional/required handling is correct and is the merge of two former implementations — good. | +| `service/serialization/SerializationUtils.kt` | Small; `buildContextual` is the right seam. | +| `java/…/RedisInvokerLookupProvider.java` | The second piece of Java; no KDoc explaining why it must be Java (`MethodHandles.Lookup` privileges, presumably). Document it. | +| `resources/lua/**` (21 scripts) | Consistent and small. Not covered by any test that executes them against a real Redis except indirectly (`BulkMutationScriptTest`). No linting. Two conventions coexist: files here, and inline strings in `SimpleSetRedisCacheLuaScripts.kt`. Unify. | +| `resources/META-INF/services/*` | Generated by AutoService; fine. | +| `jmh/…/EventTransportBenchmark.kt` | Good that it exists. Benchmarks the codec/transport only — there is no publish-throughput or dispatch benchmark, which is where H5 and H6 live. | + +### `surf-eventbus-ksp` + +| File | Findings | +|---|---| +| `ServiceProcessor.kt` | Clean, and the one-pass rationale is right. `deferred` handling is correct. | +| `ServiceProcessorProvider.kt` | Fine. | +| `model/ContractKind.kt` | Good; the FQ names it holds should be used for annotation matching (M24). | +| `model/ContractRules.kt` | M25 (asymmetric contract acceptance, silent skip). | +| `model/ServiceModel.kt` | Clean data model. | +| `model/ServiceModelFactory.kt` | M24 (simple-name matching, duplicated default). Kotlin 2.x guard syntax (`"toString" if parameters.isEmpty()`) — confirm the language version is pinned high enough in CI. | +| `codegen/QueryDescriptorCodegen.kt` / `RpcDescriptorCodegen.kt` | ~80% identical (M25); extract a `DescriptorCodegen` base taking the differing properties and the `createInstance` signature. | +| `codegen/QueryClientCodegen.kt` / `RpcClientCodegen.kt` | M26 (`!!`), duplicated constructor-property boilerplate, raw `java.util.UUID.randomUUID()` instead of a `MemberName`. | +| `codegen/InvokerCodegen.kt`, `CallableCodegen.kt`, `AnnotationCodegen.kt`, `TypeCodegen.kt` | The annotation/type reproduction (177 lines) is the cleverest code in the module and has the least documentation. Add a KDoc explaining what `@Serializable(with=)` and `@Contextual` reproduction has to preserve and why. | +| `codegen/Names.kt` | `ServiceTypeKrpc` (M1). One-constant `Names` object could merge into `ClassNames`. | +| `codegen/Util.kt` | Entirely dead (L4) — delete the file. | +| `README.md` | H8 — stale module name, stale type names, no `@QueryService`. | +| `test/CompilationSupport.kt`, `OneProcessorTest.kt`, `QueryServiceValidationTest.kt`, `FireAndForgetValidationTest.kt` | Good compile-testing coverage of the *rejection* rules. Missing: golden-file tests of the *generated output* (a change to `QueryClientCodegen` cannot break a test today), and a test that the descriptor naming convention matches what the three runtime lookups expect (H10). | + +### `surf-eventbus-platform` + +| File | Findings | +|---|---| +| `paper/PaperMain.kt` | Fine. Top-level `val plugin` accessor is unused. | +| `paper/PaperBootstrap.kt` | Sets `dataPath` on a `lateinit var` reached through a `ServiceLoader` cast (L23). | +| `paper/PaperEventBusInstance.kt` | `EventBusInstance.instance as PaperEventBusInstance` — an unchecked cast in a `get()` used everywhere; if two `EventBusInstance` implementations are on the classpath (Paper + standalone, both `@AutoService`), this throws `ClassCastException` at a random call site. | +| `velocity/VelocityMain.kt` | L22 (`runBlocking` in a constructor; `@Subscribe suspend fun`). Global mutable `lateinit var plugin`. | +| `velocity/VelocityEventBusInstance.kt` | Same cast issue. Private `Optional.getOrNull` shadow (L2). | +| `standalone/StandaloneEventBusInstance.kt` | Two constructors plus a static `configure()` side channel to get a value into a `ServiceLoader`-created instance — works, but it is the third data-path mechanism (L23) and the most fragile. | +| `standalone/StandaloneLifecycleHookImpl.kt` | `runBlocking` in `onInit` (acceptable — it is a bootstrap entry point). `configure(StandaloneEventBusInstance.serviceName, dataPath)` passes the *current* service name back into itself, so the name can never actually be set by a caller before this runs. | +| `standalone/…/StandaloneEventBusInstanceTest.kt` | The only platform test in the repo. | + +### Tests (73 files) + +Covered by the Testing Plan above. Per-file notes worth recording: + +- `suite/RedisBusSuite.kt` — the `connectedBus` helper captures a non-volatile `var connected` mutated + from coroutines; use an `AtomicBoolean` or a `Mutex`. Its KDoc documents C6's testability cost. +- `suite/EventSuiteTest.kt` — claims spec tests 1–12c, implements 1-5, 9, 10, 11, 12a. +- `rabbitmq/testing/RabbitBrokerExtension.kt`, `TestConfig.kt` — good fixtures; `TestConfig` shrinking + the retry ladder to sub-second values is exactly the reason `retryTtlMillis` is configurable. +- `testing/RequiresDocker.kt` — good; its own message admits the skip risk (C1). +- `circuitbreaker/CircuitBreakerConcurrencyTest.kt` + `MutableClock.kt` + `MutableClockTest.kt` — a + test helper with its own test. This is the standard the rest of the suite should meet. +- `structure/PackageLayoutTest.kt`, `PackageNamingTest.kt`, `InternalNotInAbiTest.kt`, + `RelocationBaseTest.kt` — architecture tests. Excellent idea, and they are why the package rename + held. They do **not** currently assert the things this audit found (naming casing, exception + hierarchy membership, no Redisson in the ABI) — extend them; they are the cheapest possible + enforcement mechanism for M1, H11 and C7. +- `core/FakeEventTransport.kt` — the fake exists and is good; there is no `FakeQueryTransport` or + `FakeAuditSink`, which is why C5 was never caught. + +### Docs + +| File | Findings | +|---|---| +| `README.md` | Genuinely good — the "Events have no durability" section is the right thing to put first. Drift: the audit table (M11), "four layers" vs the fifth system-property layer, `HANDLER_FAILED` vs `EVENT_HANDLER_FAILED`, and it does not mention `SurfRabbitApi.builder(...)` existing as a parallel entry point. No installation/coordinates section, no "how to run this locally". | +| `docs/rollout-2.0.md` | Operationally excellent — ordered, honest about silent failures, has a checklist. Will need a new step if M1's wire renames land. | +| `docs/superpowers/plans/*.md`, `specs/*.md`, `notes/*.md` (14 files, 21k lines) | Planning artefacts in German, committed to the repo, referenced from *public API KDoc* ("see plan 3", "Task 10", "Plan 4"). Either move them out of the shipped repo, or stop referencing them from KDoc that users read. `notes/2026-08-01-audit-microservice-blocked.md` is correctly referenced from a code comment — that one is fine. | +| `surf-eventbus-api/api/surf-eventbus-api.api` | The ABI dump; C7 is visible in it. Good that it exists and is checked. | + +--- + +## Closing assessment + +The engineering *judgement* in this codebase is above average — the reasoning comments, the retry +design, the chunk validation, the circuit breaker, the topology decisions, and the README's honesty +about durability are all better than typical. The problems are not judgement problems. They are +integration problems: a merge that renamed two projects into one namespace without finishing the +job, shipped without any automated verification. + +The two changes with the highest ratio of value to effort are, in order: **CI that runs the tests**, +and **deleting the `redisConfig` global**.

Redis had three of those: it passed the *platform* plugin's folder as both the global and the plugin layer, so the `eventbus-plugin.yml` it opened sat next to `eventbus.yml` in a folder no consumer owns, and nothing a plugin wrote could reach Redis. RabbitMQ, one function away, had it right. Which files feed the layers is now decided in one place — `resolveEventBusSettings`, next to the `resolveEventBusConfig` that applies them — and both transports ask it the same question. `SurfRabbitApiBuilder.resolveConfig` delegates to it rather than answering separately. `redisConfig` stays, and stays the Redis half's entry point, but it is keyed by the consumer's data folder instead of being one `by lazy` fixed on first touch: the plugin layer is per plugin by definition, so a single process-wide value could not express it, and on a server with two plugins whichever touched Redis first decided for both. `RedisSettings` is threaded from the bus builder through `RedisTransportProvider` into `RedisApi.create`, `RedisCredentialsProvider` and `RedissonConfigDetails`, so `clientName` comes from the same resolution as the host rather than from a global the plugin layer never reached. That also makes the production path testable, which it had never been. The Redis suites built their buses through the `withRedis(event, query)` seam because a process-wide value could not be pointed at a container — so the wiring real callers use was the one thing those suites never exercised. They go through `withRedis()` now, each bus with its own data folder holding the `eventbus.yml` an operator would write. 17 suite tests moved onto it. **C7 — no relocated third-party type is left in the published ABI.** The dump named `io.netty.buffer.ByteBuf` 85 times and `org.redisson` 5, all in the codec surface: `AbstractCodec : org.redisson.client.codec.BaseCodec`, `RedisCodec`, `BusEventCodec`, the `ByteBuf` read/write helpers, and three Java types. The shadow jar relocates both packages, so those signatures named types a consumer compiling against the artifact cannot resolve, and a Netty upgrade was a breaking change for anyone who managed it. All of it is `@InternalEventBusApi` now — declared internal, not hidden by an ABI filter rule, so using it still requires opting in knowingly. `BusEventCodec` is the one a consumer has real reason to implement and says so; the way out is a buffer type of our own. netty, redisson, reactor and RedisURI: 0 occurrences each. **The two missing Tier-2 tests.** Both were confirmed to fail against the defect before being kept: - `EventBusConfigFileLayeringTest` — which file each layer is read from (C6). Three of its five cases fail if the plugin layer is read from the platform folder. - `TimeoutSettlementTest` — a timed-out handler republishes exactly once (H4). The timeout branch settles the delivery *and* cancels the job, completing the handler and waking the second party with an opinion about the same message; settling twice parks two copies on the retry tier and the ladder doubles at every rung. This branch and topology-redesign fixed that two different ways and the merge combined them, with nothing pinning the result until now. **Step 1 — ktlint, with a per-module baseline, in `check`.** Detekt is deliberately absent, and `docs/development.md` says why: 1.23.8 embeds Kotlin 1.9's compiler, whose `JvmTarget` stops at 22, and it reads that target from the JVM it runs on — the Gradle daemon, because it invokes its CLI in-process rather than forking. On a JDK 25 toolchain every task dies with a bare `IllegalArgumentException: 25` before opening a file, and there is no fork to point at another JDK. No 2.x is released. Also: `org.gradle.jvmargs`. The daemon defaults (512m heap, 384m metaspace) run out part way through a full `check`, which surfaces as an OOM or an `EOFException` from a KSP worker rather than as anything naming memory. Verified: ./gradlew check -PrequireIntegration — 286 passed, 0 failed.

EventBusTransporter now owns freeze/connect/disconnect for both transports. `connection` is abstract, a failed connect tears down through the normal disconnect path rather than each transport hand-rolling cleanup, and disconnect is idempotent and terminal. Redis gets a real EventBusConnection: RedisConnection owns the Redisson clients, the initializable/disposable registries and the OS probe, leaving SurfRedisApi as registration and serialization. Its dead syncStructureScope is gone and redisListenerScope folds into the inherited scope. Two bugs in the in-flight work: - CircuitBreaker.open() took the Mutex while its only caller onFailure() already held it. A Mutex is not reentrant the way the synchronized block it replaced was, so the breaker self-deadlocked and CircuitBreakerConcurrencyTest hung. onSuccess/onFailure now run NonCancellable as well: a Mutex refuses to lock in a cancelled coroutine, which would strand probeInFlight and leave the breaker rejecting for good. - EventBusInstance lost getResourceAsStream, tryExtractPluginName and orNull, all of which surf-eventbus-core still calls. Restored without the delegating companion, because a top-level requiredService() throws at class-init and orNull() has to answer for a process that registered no platform - the same reasoning StandaloneLifecycleHook already carries. RedisCredentials was an empty data class and RedisCredentialsProvider did not satisfy its own CredentialsProvider seam. redisURI() now takes the credentials rather than the settings, so a provider sourcing the password from a vault actually gets it into the URI instead of having it computed and discarded. Codestyle, repo-wide: package declarations follow the directories the files were moved into, and twelve main-source files holding more than one top-level type are split one-per-file. Test fixtures are left alone - several sit next to the single test that uses them and splitting those costs readability. SurfRedisApiBuilder was an empty stub; it now mirrors SurfRabbitApiBuilder and is the only route that can express the per-plugin config layer, which none of the seven create(...) overloads can. ABI dump updated. SurfRedisApi.connection stays protected and SurfRabbitApi's is annotated, so neither re-exports a connection type through the published surface. Verified with `check -PskipIntegration`: 218 tests, ktlint, lincheck, ABI check. The testcontainers suites did not run - no Docker daemon on this machine - and they are exactly what covers the Redis connect path this moves.

Otherwise the clearest class in the repo — the `require*` error messages are a model for the rest. | -| `core/SurfEventBusBuilderImpl.kt` | C8. `withRedis()` eagerly resolves three SPI objects at builder time, before `build()`; a failure surfaces at the wrong place. | -| `core/SurfEventBusFactoryImpl.kt` | Fine. | -| `core/RedisTransportLocator.kt` | Stale module name. Declares `RedisTransportProvider` in the same file (M2) — and that interface is what `SurfEventBusFactory`'s KDoc tries to link to from another module. | -| `core/audit/LoggingAuditSink.kt` | Fine; nine positional `%s` in one log line is at the limit of readability. | -| `core/dispatch/EventDispatcher.kt` | C2, H3, H6, M10, X4. The `warnedTypes` "warn once" mechanism duplicates `EventTypeResolver`'s negative cache (L4). | -| `core/dispatch/QueryDispatcher.kt` | H3, H10, M23, X4. `Class.forName` outside the `try` in `DescriptorCache` (H10). | -| `core/dispatch/BusEventCodecs.kt` | Neat. `getDeclaredField("Companion").isAccessible = true` will hit module access restrictions on a JPMS classpath; catch `InaccessibleObjectException` too. | -| `core/dispatch/EventTypeResolver.kt` | H3. The `SurfBusEvent` assignability guard before caching is a genuinely good security decision, and the comment says so. `isKnownUnresolvable` is dead. | -| `core/registry/EventSubscription.kt` | German KDoc (L3). | -| `core/registry/EventSubscriptionRegistry.kt` | C2, L12, L13. `trySetAccessible` with the explanatory comment is excellent. | -| `core/registry/QueryServiceRegistry.kt` | `timeoutOf` is production-dead (L4). Otherwise clean. | -| `platform/EventBusPlatformInstance.kt` | L21 (empty `onEnable`). Correctly uses `NonCancellable` on shutdown. | -| `rabbitmq/connection/RabbitConnectionImpl.kt` | C10 (indirect), H2, M12, M13, L1, L4. The single most complex file; the comments are good enough that the complexity is *legible*, which is why decomposition is safe. | -| `rabbitmq/connection/RabbitClient.kt` | M4 (hardcoded 8 + 16 threads in a static initialiser), M20 (10 s sleep), M1 (stale `RabbitMQApi` in user-facing text), M3. `activeClients` retains clients strongly for leak reporting — the leak detector prevents the collection it detects. | -| `rabbitmq/connection/RabbitConnectionProvider.kt` | C10. Declares an exception (M2). Otherwise a careful, correct state machine. | -| `rabbitmq/connection/ReturnListenerBridge.kt` | Unbounded `scope.launch` per returned message — a routing outage becomes a coroutine storm. The self-audit guard (`routingKey != auditServiceName`) is a good catch. | -| `rabbitmq/connection/RabbitConnectionListener.kt`, `RabbitConnectionSnapshot.kt`, `RabbitConnectionStatus.kt`, `RabbitClientHealthSnapshot.kt` | Small and clean. | -| `rabbitmq/connection/RabbitConnectionFactoryImpl.kt` | Fine. | -| `rabbitmq/consumer/RabbitConsumer.kt` | M4 (a thread per consumer; the `declare` consumer is never released). `getChannel` is `suspend` and blocks transitively (C10). | -| `rabbitmq/consumer/RabbitAck.kt` | M15 (duplicate methods, dead `reject`). | -| `rabbitmq/consumer/RabbitListenerHandlerManager.kt` | H4, X4 (two hand-built reports), `retryEnabledFor` ignores its parameter (M16), `(api.rpcService as RabbitRpcServiceImpl)` breaks its own abstraction. The nested try/catch/`invokeOnCompletion`/`AtomicReference` control flow is the hardest code in the repo to verify; `runCatching { handlerJob.join() }` expresses most of it. | -| `rabbitmq/publisher/RabbitPublisher.kt` | H5. `channel` is a non-volatile `var` confined to the dispatcher thread — correct but undocumented; add a comment or `@GuardedBy`. | -| `rabbitmq/publisher/RabbitPublisherPool.kt` | L10 (thread naming). Round-robin via `getAndIncrement` can overflow — `floorMod` handles it correctly; good. | -| `rabbitmq/publisher/MessageKind.kt` | Well designed, well documented, tested. | -| `rabbitmq/publisher/RabbitPublisherOptions.kt` | Not reachable from configuration — `RabbitClient.create` takes a default and nothing overrides it. Either expose it or inline the constants. | -| `rabbitmq/packet/RabbitPacketChunking.kt` | M21 (`decodeOrNull` throws), M22 (duplicated header size). The metadata validation against remote input is thorough and correct — the best security work in the repo. | -| `rabbitmq/packet/RabbitPacketChunkAssembler.kt` | L18, L19. The lock-free `PartialPacket` is correct and well commented. Opportunistic cleanup means a stalled series survives until the next `accept`. | -| `rabbitmq/packet/RabbitPacketSerializer.kt` | `readRemainingBytes` copies the payload on every deserialisation; decoding from the `ByteBuf` slice would avoid it. `buf.array()` assumes a zero-offset heap buffer — true here, fragile. L1. | -| `rabbitmq/packet/RabbitPacketPropertiesInjector.kt` | A 10-line object that mutates two fields on a wire packet (M14). Disappears if `RabbitRequestPacket` is split. | -| `rabbitmq/rpc/RabbitRpcServiceImpl.kt` | H10, L15, L14, L1. `serviceIdCounter`/`callCounter` are per-instance `AtomicLong`s whose values go on the wire — document their scope. | -| `rabbitmq/rpc/RpcServiceExecutor.kt` | M17 (different logger), L16. The `fireAndForget` rethrow path and its comment are correct and subtle. | -| `rabbitmq/rpc/BreakerGuardedRpc.kt` | Very good — the `isTransportFailure` KDoc explaining why `SurfRabbitRequestTimeoutException` is deliberately excluded is exemplary. Well tested. | -| `rabbitmq/rpc/RpcErrorResponses.kt` | Fine; version-gated legacy support is clean. | -| `rabbitmq/rpc/RabbitRpcServiceFactoryImpl.kt` | L1 (two self-imports in a 13-line file). | -| `rabbitmq/rpc/exception/SerializedException.kt` | 199 lines reconstructing exceptions from the wire. Not reviewed line-by-line for this audit beyond confirming it is only reachable from the RPC error path; **it deserves its own security review** — it is remote-input-driven exception construction, and the class-name → `Throwable` path is exactly where deserialization gadgets live. Add it to the test plan (Tier 1). | -| `rabbitmq/rpc/packet/RpcCallRequestPacket.kt`, `RpcCallResponsePacket.kt` | Clean sealed response model. | -| `rabbitmq/topology/RabbitTopology.kt` | Good. `sanitize` idempotence is documented and untested (Tier 4). | -| `rabbitmq/topology/RabbitTopologyDeclarer.kt` | Excellent KDoc — the `406` explanation and the "no alternate exchange" rationale are the kind of comment that prevents a regression. L11. | -| `rabbitmq/topology/QueueArguments.kt` | Good. `MAX_QUEUE_BYTES` (256 MiB) is not configurable; on a shared broker an operator will want it to be. | -| `rabbitmq/retry/RetryPolicy.kt` | M16. The `x-death` investigation write-up is the best comment in the repo. | -| `rabbitmq/retry/RetryPublisher.kt` | C4, L20. | -| `rabbitmq/audit/AuditReports.kt` | M9, X4. Good design, wrong home (core, should be api). | -| `rabbitmq/audit/RabbitAuditSink.kt` | H2. The flood control and self-audit suppression are well reasoned. `enabled` is a dead parameter. | -| `rabbitmq/audit/AuditMessageIdentity.kt` | C4; `stamp` is production-dead (L4). | -| `rabbitmq/health/RabbitMQMicroserviceHealthContributor.kt` | Fine. No Redis equivalent — an operator gets half a health picture. | -| `rabbitmq/credentials/RabbitCredentialsProviderImpl.kt` | Fine. | -| `redis/RedisRuntime.kt` | M4 (16 Netty threads + 8 + 2 schedulers, none configurable). The context-classloader swap in `init` is a real Redisson workaround and is well commented. | -| `redis/TransportInfo.kt` | M3, `data class` over a factory (M3 note). | -| `redis/RedisComponentProviderImpl.kt` | M5 (hardcoded Redisson tuning, unused `serializerModule`). `clientId` derived from the first two UUID segments is 16 hex chars of entropy — fine, but it is the `origin` field in every sync stream message, so document the collision domain. | -| `redis/config/RedisConfigAccess.kt` | C6 — the file to delete. | -| `redis/credentials/RedisCredentialsProviderImpl.kt` | The colon-prefix comment documents a real, previously-shipped bug — good. The password ends up inside a `RedisURI` whose `toString` is not ours (M7). No username/ACL support. | -| `redis/bus/RedisEventTransport.kt` | C3, L4 (`log`), X2. | -| `redis/bus/RedisQueryTransport.kt` | Correct where the event transport is not. Decodes JSON on the Redisson listener thread in `subscribeReply` while `subscribeQuery` launches into a scope — inconsistent. | -| `redis/bus/RedisChannels.kt` | Good, tested; the "why two families" KDoc is exactly right. | -| `redis/bus/BinaryFrame.kt` | `String(header)` uses the platform default charset — should be `Charsets.UTF_8` (it round-trips with `toByteArray()`, which is also platform-default; both are wrong together, so it works until two processes have different defaults). **Fix this**: it is a latent cross-platform wire bug. | -| `redis/bus/RedisTransportProviderImpl.kt` | Eagerly constructs `RedisApi.create()` at `ServiceLoader` instantiation, so `getCallingPluginName()` attributes the connection to the wrong class (M19). `ensureConnected` freezes the api implicitly. | -| `redis/sync/AbstractSyncStructure.kt` | `.block()` on dispose (M18). `NAMESPACE = "surf-redis:sync:"` (M1). | -| `redis/sync/AbstractStreamSyncStructure.kt` | H7 (fire-and-forget writes), X3. 397 lines, six responsibilities. The hand-rolled `parseVersion` and delimiter scanning are optimisations without a benchmark behind them; `StreamEventData.payload(index)` is O(n·index). Inconsistent malformed-message handling (log-and-return vs throw). | -| `redis/sync/SyncValueCodec.kt` | Base64 over a `StringCodec` stream costs 33% on the wire; a `ByteArrayCodec` stream would avoid it. Bounds checks are good. | -| `redis/sync/{list,map,set,value}/Sync*Impl.kt` | Consistent, readable, entirely untested (Tier 1). All inherit H7. | -| `redis/cache/SimpleRedisCacheImpl.kt`, `SimpleSetRedisCacheImpl.kt` | X3 — 1,242 lines duplicating `AbstractStreamSyncStructure`'s machinery. Untested. `SimpleSetRedisCacheImpl` at 807 lines with 20 public methods is the largest class in the repo. | -| `redis/cache/SimpleSetRedisCacheLuaScripts.kt` | 448 lines of Lua in Kotlin string constants — no syntax highlighting, no linting, no tests, and it duplicates the `resources/lua/` approach used everywhere else. Move these to `.lua` resources for consistency (the loader already exists). | -| `redis/util/DisposableAware.kt` | Correct; the post-add re-check is subtle enough to deserve its comment. | -| `redis/util/LuaScriptExecutor.kt` | `NOSCRIPT` retry handling is good. Nested weak Caffeine caches keyed by `RedisApi` and `LuaScriptRegistry` — clever, and the KDoc is longer than the code; a plain field on `RedisApi` would be simpler. | -| `redis/util/LuaScriptRegistry.kt` | L24 (platform-classloader resource loading). | -| `redis/util/RedisExpirableUtils.kt` | `.repeat().subscribe()` — an unkillable refresh loop per structure unless the `Disposable` is tracked (it is). Fine. | -| `redis/util/RedisStreamsUtils.kt` | `Result.handler()` as a callback shape is unusual but readable. 250 ms polling per structure per process — with many structures this is a lot of Redis traffic; note it. | -| `serialization/KotlinSerializerNameCache.kt` | Fine; merge with `KotlinSerializerCache` (L16). | -| `service/serialization/ServiceSerializerCache.kt` | L16 (one per component). | -| `service/serialization/ParametersSerializer.kt` | L17 (shared serial name). The optional/required handling is correct and is the merge of two former implementations — good. | -| `service/serialization/SerializationUtils.kt` | Small; `buildContextual` is the right seam. | -| `java/…/RedisInvokerLookupProvider.java` | The second piece of Java; no KDoc explaining why it must be Java (`MethodHandles.Lookup` privileges, presumably). Document it. | -| `resources/lua/**` (21 scripts) | Consistent and small. Not covered by any test that executes them against a real Redis except indirectly (`BulkMutationScriptTest`). No linting. Two conventions coexist: files here, and inline strings in `SimpleSetRedisCacheLuaScripts.kt`. Unify. | -| `resources/META-INF/services/*` | Generated by AutoService; fine. | -| `jmh/…/EventTransportBenchmark.kt` | Good that it exists. Benchmarks the codec/transport only — there is no publish-throughput or dispatch benchmark, which is where H5 and H6 live. | +| File | Findings | +|------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| +| `core/SurfEventBusImpl.kt` | C2 (via the dispatcher), C5, H1, H13, `!!` at line 148, unused `dataPath`, third descriptor cache (H10).
