AntiPattern

Host-Side Authority Mismatch

host-authority-misuse

RPC and state authority get misapplied when host-only semantics or host-authoritative sync are invoked from clients, causing broadcasts to fail or selections/desync to occur while UI/game-state updates run on the wrong authority context.

MATCHESSolution

Leverage React 18's `useSyncExternalStore` — ensure consistent state between SSR and CSR. Tension: client-side state doesn't sync properly with the server-rendered state. Outcome: to ensure consistent state between SSR and CSR.

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

Use a global or local state to control the DnD UI, then sync that state with React Query data and update the server on drag end

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

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

Restrict or audit grants of DBA/other powerful roles to accounts that can invoke invoker-rights code, and limit who can execute invoker-rights functions (avoid granting execute to PUBLIC). Prefer safer security patterns (e.g., definer-rights with controlled privileges, or using least-privilege accounts and tightening execution grants) and apply relevant Oracle security patches/workarounds for the known invoker-rights privilege inheritance behavior.

MATCHESSolution

My solution was to allow only the user the process is running under, and deny NT AUTHORITY\NETWORK. — before the code above. Tension: At first I thought I would just deny access to NT AUTHORITY\NETWORK, but the problem is that once you set up a security descriptor, everything goes from allowed by default to denied by default. Outcome: adding this before the code above.

MATCHESSolution

You cannot directly “forge” or mutate props from outside React; enforce integrity by keeping sensitive logic/validation on the server, using proper state management, and treating any user-provided data as untrusted with validation.

MATCHESSolution

Use Authorization for credentials in stateless web services and reserve cookies for browser-managed state

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

run a signaling server in the browser — For a mostly offline browser game. Tension: I don't think that you can run a signaling server in the browser. Outcome: run the signaling server in the LAN, and have the peers connect to it.

MATCHESSolution

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

MATCHESSolution

case "CallbackRouteError": return { error: "Invalid credentials!" } — in my `login.ts` server action in the switch case clause. Tension: to return the correct errors. Outcome: bypass this error.

MATCHESSolution

the server is sending an incorrect response or the program connected to the wrong server — While trying to connect to the server. Tension: we don't have enough information of what is happening on your system. Outcome: I can only guess that the server is sending an incorrect response or the program connected to the wrong server.

MATCHESSolution

Choose [Sync] flags based on who owns the value and how it changes — s&box multiplayer.

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

CollectSyncState() iterates all components, finds [Sync] properties without [Property], serializes them to JSON — in SaveSystem.cs. Tension: Use JSON serialization first, with a ByteStream/BytePack fallback for types that don't serialize cleanly to JSON. Outcome: RestoreSyncState() is called before RestoreNetworkOwnership() in the Load path.

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

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

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

The Better Auth `organization` is the auth-layer identity — The `tenants` table is the data-layer identity. Tension: They serve different masters. Outcome: coexisting is fine.

MATCHESSolution

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

MATCHESSolution

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

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

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.
