AntiPattern

Host-Authority Invocation Misuse

host-authority-rpc-misuse

Host-only RPCs and host-authoritative patterns get invoked from clients, so replicated state changes and UI logic never apply (or apply inconsistently) because ownership, networking callbacks, and sync attributes aren’t aligned with call origin.

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

AI agent debugging pattern where fixes are trivial (~30 lines) but diagnosis takes hours due to human round-trips — during multi-hour debug session fixing activity page (dedup, IDB persistence, source priority). Tension: Each round costs minutes of wall-clock time. Outcome: Eliminates ping-pong entirely when self-test infra is in place.

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

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

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

[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

chown-core.c:211-262. Outcome: openat+fstat+SAME_INODE+fchown.

MATCHESSolution

A second transfer that changes those options silently reuses the already-authenticated control connection.

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

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

Universal hook set for MCP behavioral activation. Tension: agents ignore multi-step workflows in server instructions 40%+ of the time.

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

Removed lazy registration from the shared MCP call path — shared MCP call path. Outcome: restored direct gating using the original agent id.

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.

MATCHESSolution

Rebuilt App.tsx as the OracleController beat machine. Outcome: running the authored cascade arrest→anchor→recognition→locked on setTimeout timers.
