AntiPattern

Host-Scoped Execution Semantics

host-scoped-rpc-semantic-mismatch

Host-scoped RPCs and host-only execution paths silently diverge from client expectations: invoking [Rpc.Host] or host-owned state from a client does nothing, while missing the right host sync/cancellation semantics causes replication, scheduling, or async lifetimes to break.

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

Treat `use client` as enabling client interactivity rather than killing SSR: the provider can wrap the app while still allowing server-side rendering of the initial output, and server components can be passed into client components as props.

MATCHESSolution

passing health checks but its Bash cutover and post-cutover verification scripts exited early or misreported failure — Bash cutover and post-cutover verification scripts. Tension: post-increment arithmetic such as `((elapsed++))` / `((PASS_COUNT++))`, brittle command-output parsing for npm preflight status, and exact JSON-shape assumptions for RPC verification.

MATCHESSolution

You can use a different overload to get the hosting context, services, and configuration. — builder.Host.UseSerilog((hostContext, services, configuration) => {. Tension: configure sinks, etc. Outcome: configuration.WriteTo.Console();.

MATCHESSolution

Added an early clause in isReplayableMigration's per-statement check. Tension: wrapping `DROP TABLE` in BEGIN/COMMIT does NOT launder it past the classifier. Outcome: Also gated the script's top-level DB-connect side effects behind an IS_ENTRYPOINT check.

MATCHESSolution

Make sure this is set! — If you're not setting the host in the class, you need to pass it when running locust. Tension: The actual problem is probably your data format.

MATCHESSolution

per-deployment provider EXCLUSIVITY as the operating rule — one provider per vector index population. Tension: mixing spaces silently corrupts similarity. Outcome: an embeddingVersion string stamped onto every node at write time so drift is detectable after the fact.

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

Store only the primitive/client construction parameters (e.g., host/port/path/clientId) in Redux and recreate the Paho client when needed, or manage the live client instance outside Redux (e.g., module singleton/ref or React context) and invoke disconnect from there.

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

Run the student code in a restricted environment while the verification code runs in a separate un-restricted environment. Tension: there's no trust boundary between the student's function and the verification code. Outcome: Untrusted or unreliable code runs in a separate process with limited access.

MATCHESSolution

If this is not feasible, the namespace variant should be used. — Distributed applications generating UUIDs at a variety of hosts. Tension: must be willing to rely on the random number source at all hosts. Outcome: the namespace variant should be used.

MATCHESSolution

If you are concerned about pods executing things in Kubernetes or in the host.

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

[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

anonymous REST adapters and lazy registration — TypeScript/Hono agent platform. Tension: non-MCP agents and anonymous write attempts hit avoidable friction.

MATCHESSolution

The RPC uses Rpc.Caller.HasPermission("admin") for authorization — admin RPCs. Tension: before executing. Outcome: always check `Rpc.Caller.HasPermission("admin")` before executing.

MATCHESSolution

Store ownership as a `[Sync(SyncFlags.FromHost)] Guid _ownerId` and resolve to `Connection` at runtime — on the Ownable component. Tension: cancel grabs/selections when the caller doesn't have access.

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

Use `NetDictionary<string, int>` keyed by `AmmoResource.ResourcePath` — with `[Sync(SyncFlags.FromHost)]`. Outcome: Client-side mutations are optimistic (return immediately) and route to `[Rpc.Host]` for authoritative validation.

MATCHESSolution

Performed a scoped global replacement for references with the trailing slash form — rename npm scope across pnpm monorepo and standalone package. Tension: without breaking workspace publishes. Outcome: regenerated lockfiles, and verified package tarballs.

MATCHESSolution

Hono runs on top of Node's `http.IncomingMessage`/`ServerResponse`. Tension: otherwise it'll try to double-write headers. Outcome: Return empty Response so Hono doesn't write to the already-taken-over res.

MATCHESSolution

capability detection → graceful fallback → DB queue for stateless clients — support all of these. Tension: There's no single mechanism that works everywhere. Outcome: capability negotiation is the only viable pattern.

MATCHESSolution

both auth paths set the same session variable — during transition. Outcome: SET LOCAL app.tenant_id = agent.orgId.

MATCHESSolution

Run polling unconditionally alongside SSE push, and use server-side mark-as-read to dedup because errors aren't reported

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

Use for persistent state that all clients need. — [Sync] Attribute - State Replication. Outcome: Use for actions, events, and host-authoritative operations.

MATCHESSolution

Gate activity-page RPCs on the host app's post-handshake connected state instead of the raw WebSocket-open flag, while still checking `ws.readyState === 1` — activity-page RPCs. Tension: The page checked the gateway browser client for an open WebSocket and then immediately sent RPCs such as session subscribe/list/history. Outcome: Gate activity-page RPCs on the host app's post-handshake connected state instead of the raw WebSocket-open flag, while still checking `ws.readyState === 1`.

MATCHESSolution

Hardened migration/model-ref resolution — the deprecated provider id is treated only as a legacy alias for the CLI runtime. Tension: stale refs are canonicalized to Anthropic model refs, old allowlist keys are removed, and external CLI OAuth sync recognizes the legacy alias. Outcome: external CLI OAuth sync recognizes the legacy alias.
