AntiPattern

Host-only Async/Effects Misfires

wrong-context-host-scoped-and-early-destruction

Host-scoped operations and effect lifetimes fail when invoked from the wrong execution context or when owning objects get destroyed early, causing broadcasts not to replicate, async tasks to continue, and mid-play effects to get cut off.

MATCHESSolution

Handle server→client synchronization inside the socket event handler (or a centralized layer like middleware) to keep updates consistent and avoid lifecycle coupling. Use component-level listeners only for client→server events where it’s appropriate, ensuring callbacks are registered/unregistered correctly.

MATCHESSolution

handle a scenario when the code is fine but backend went offline — prefetching data with usePrefetchQuery. Tension: prefetch works.

MATCHESSolution

Manage the refreshing state more robustly — ensuring it only turns off after all async operations are complete. Tension: remove the arbitrary timeout. Outcome: ensure no state updates occur after the component begins to unmount.

MATCHESSolution

post-start failures. Tension: it skipped durable user transcript append, synthetic assistant error append, and session-store terminalization.

MATCHESSolution

Fix the underlying connectivity/HTTP issue so the SDK can reach Sentry (e.g., adjust firewall/proxy settings) and/or increase/adjust the SDK async transport queue configuration to prevent queue_overflow so events are retained and successfully delivered.

MATCHESSolution

single worker running async loop. Outcome: So you have a single worker running async loop and you block that loop.

MATCHESSolution

Change the engine async fixture from session scope to function scope (remove scope="session") so all async fixtures/tests run on the same event loop, preventing the cross-loop Future/Task error.

MATCHESSolution

any time you have an I/O bound process with lots of idle time — waiting for user input, waiting for a TLS handshake. Tension: wrapping it in an async task can let other code run.

MATCHESSolution

Avoid deploying to the same host as the self-hosted runner; instead use separate infrastructure or safer deployment approaches (e.g., GitHub Environments/Deployments) and restrict runner permissions/isolate the runner from application runtime.

MATCHESSolution

bound it with a "progress ceiling" — a process emitting bytes but making NO semantic progress. Tension: a process emitting bytes but making NO semantic progress (livelock) would be shielded forever. Outcome: re-arms recovery after a long no-progress window even while bytes flow.

MATCHESSolution

Keep two listeners or refactor so one wrapper function registers both listeners that call the same shared effect logic; alternatively, create a single predicate/matcher that encompasses both conditions if feasible.

MATCHESSolution

An async function was passed to useActionState.

MATCHESSolution

Avoid running multiple DB operations concurrently on the same session by removing asyncio.gather and iterating sequentially, and/or use an async_scoped_session so each task uses its own session.

MATCHESSolution

depending on your latency budget. Outcome: Same idea, but the state lives outside the process boundary.

MATCHESSolution

Stage 2 (startup). Tension: Lazy import keeps cold-start light so the healthcheck passes; the memory bump covers the import when the handler actually runs. Outcome: functions-framework can bind the port.

MATCHESSolution

the goroutine blocks forever on the channel send because nobody is reading — When the parent context is cancelled, the goroutine blocks forever on the channel send because nobody is reading. Tension: if the result is ready at the exact moment the context cancels, which case fires?

MATCHESSolution

[Rpc.Host] — called on host only. Call from any client to run logic on host. — Three RPC attributes with distinct semantics. Tension: Never trust client input in [Rpc.Host] — always validate.

MATCHESSolution

Use Component.Task (TaskSource) for all async work inside components — inside components. Tension: it auto-cancels when the component is destroyed.

MATCHESSolution

Add TemporaryEffect to GameObjects that should auto-destroy after effects finish — In the scene editor: add TemporaryEffect component to your effect prefab. Outcome: BecomeOrphan = true: if parent is destroyed, detach and finish playing.

MATCHESSolution

Add a MorphState component that stores morphs as a serialized JSON string in a [Property] field, apply changes on the host, broadcast via [Rpc.Broadcast], and restore in OnStart().

MATCHESSolution

Implement `Local.IPlayerEvents.OnLand(float distance, Vector3 velocity)`. — From PlayerFallDamage.cs. Tension: Call `[Rpc.Broadcast]` with host guard to apply damage on host. Outcome: Play fall sound via `[Rpc.Owner]` so only the owning client hears it.

MATCHESSolution

Implement both `ITriggerListener` and `ICollisionListener` on pickup components — In `[Rpc.Broadcast]` sound effects. Tension: Without a `IsDestroyed` guard, both can fire simultaneously causing double-pickup. Outcome: set `snd.SpacialBlend = 0` when `player.IsLocalPlayer` for 2D sound, leave default (3D) for others.

MATCHESSolution

Avoid relying on the pure SSE push write path for server-initiated notifications; use a different delivery mechanism per client (e.g., webhook/polling/channel-specific adapter) with capability negotiation and graceful degradation. Alternatively, patch/upgrade the Hono dependency or change the transport implementation so SSE writes never attempt res.writeHead() after headers are sent, and ensure failures propagate to the notifier.

MATCHESSolution

Don't build per-client adapters. — client capabilities change with updates. Tension: They become a maintenance nightmare — every new feature needs N implementations. Outcome: one delivery function that degrades.

MATCHESSolution

record that the side effect fired, check before firing again — awarding XP, delivering a notification, processing a queue item. Outcome: All three are instances of the same principle.

MATCHESSolution

ShootEffects is [Rpc.Broadcast] — muzzle flash/impact effects. Tension: for muzzle flash/impact effects. Outcome: [Rpc.Broadcast].

MATCHESSolution

Implement `Component.ICollisionListener` on projectiles — Projectile.cs and TimedExplosive.cs. Tension: host only. Outcome: Trigger explosion via `[Rpc.Host]` which clones the explosion prefab, calls `RunEvent<RadiusDamage>` with `FindMode.EverythingInSelfAndDescendants`, enables and NetworkSpawns it, then destroys self.

MATCHESSolution

Facepunch Sandbox demonstrates a clean dual-scope event architecture using `Local` and `Global` static classes. Tension: Difficulty implementing cancellable events.

MATCHESSolution

Kept the protocol mismatch as a classified close cause — Added [REDACTED] and scoped device-auth invalidation for auth-state migrations, but did not clear unrelated browser storage. Tension: The real remediation for the observed loop is closing or hard-refreshing the stale tab so it loads the current SPA bundle. Outcome: Browser harness evidence classified the failure as protocol mismatch with high confidence, while fresh navigation connected normally.

MATCHESSolution

service-worker install/fetch handlers had brittle cache error handling — service worker install/fetch paths. Tension: brittle cache error handling. Outcome: tolerant precache and explicit offline responses.
