Package cachetest provides cache test doubles shared across app-layer tests.

Package semantic provides a Redis Stack (RediSearch) vector store used by the semantic cache plugin to look up and persist responses by embedding similarity, scoped per rule via a hashed tag.

Package grpc implements the config-sync gRPC transport: the control-plane server, the data-plane client, the connection hub, and the auth interceptors and credentials that secure the channel.

Package migrations registers in-code schema migrations via init().

Package playground stores the metrics Event of playground proxy requests in Redis so the dashboard can fetch the trace by TraceID (the X-AG-Trace-Id echoed in the proxy response).

Package cors implements a PreRequest CORS plugin that validates the request origin, applies CORS response headers, and short-circuits preflight requests.

Package llmcost holds the model-pricing primitives shared by the LLM budget and cost cap plugins: glob matching of model slugs, price resolution, model downgrade, and the stateless cost cap decision engine.

Package semanticcache implements a semantic response cache: on PreRequest it serves a cached response when a semantically similar request is found, and on PostResponse it stores successful upstream responses for future hits.

Package openaicompat implements a provider client for arbitrary OpenAI-compatible Chat Completions endpoints (Together, Fireworks, vLLM, Ollama, self-hosted gateways, ...).

Package configsyncconn provides the pgx-backed adapter over config_sync_connections: the write side the config-sync Hub calls best-effort to record data-plane stream lifecycle, and the read side the admin API lists.

Package outbox provides the pgx-backed adapter for the config-snapshot change-marker outbox: an in-transaction appender the admin repositories share, plus the drain/prune reads the dispatcher runs.
