/**
 * RPC schema markers and interruption annotations.
 *
 * This module contains the small pieces of schema metadata that the RPC
 * declaration, client, server, cluster, and reactivity layers share. It marks
 * streamed responses and annotates interruptions that came from a remote client
 * closing or cancelling a request.
 *
 * **Mental model**
 *
 * A streaming RPC still has a normal RPC exit, but its success schema is marked
 * with {@link Stream}. The marker stores the stream element schema and the
 * stream error schema so transports can encode and decode each chunk while
 * keeping stream failures on the chunk stream.
 *
 * **Common tasks**
 *
 * - Use {@link Stream} when constructing RPC metadata directly
 * - Use {@link isStreamSchema} to branch between one-shot and streaming
 *   responses in protocol implementations
 * - Read the stored `success` and `error` schemas when encoding or decoding
 *   stream chunks
 * - Use {@link ClientAbort} to tag interruptions caused by client disconnects
 *
 * **Gotchas**
 *
 * - `Rpc.make(..., { stream: true })` installs this marker for you
 * - For streaming RPCs, the immediate RPC exit succeeds with `void`; stream
 *   elements and stream errors are encoded separately
 * - Request payload schemas live on the `Rpc` definition, not in this module
 * - `Stream` is RPC metadata, not a general-purpose codec for arbitrary
 *   `Stream` values
