//! Deployable HTTP, gRPC, WebSocket, and worker endpoint for Aion workflows.
//!
//! This crate wraps the transport-agnostic engine with API handlers, namespace
//! isolation, observability, shutdown handling, ops-console assets, and
//! remote-worker task dispatch.
//!
//! # Example
//!
//! ```
//! use aion_server::ServerConfig;
//!
//! let config = ServerConfig::default();
//! println!("serving gRPC on {}", config.server.grpc_address);
//! ```

/// HTTP, gRPC, and worker API handlers.
/// Transcript retention bounds: per-event size truncation for the durable `O`
/// keyspace (`[observability]` config).
pub(crate) mod activity_bounds;
/// NOI-5 transcript sequencer + live fan-out — commit-allocated `store_seq` over
/// the durable `O` keyspace, plus the resumable transcript broadcast.

/// Server-side Gleam authoring surface (compile, type-check, package, hot-load).

/// The built-in assistant: the embedded AWL document, its boot install, and
/// the description the server serves of it.
pub mod assistant;
/// In-process AWL checking, formatting, semantics, and workspace documents.
pub(crate) mod awl;
/// What code this server is: the revision stamped into the binary at build

/// "What's new" panel: what changed in the version this server RUNS, never a
/// file read from disk.
pub mod changelog;
/// SS-5b automatic multi-node failover detection (cluster supervisor). Only
/// meaningful for a distributed (`[store.cluster]`) boot; dormant otherwise.

/// WS3 cluster topology/ownership broadcast publisher. The ops console's cluster
/// channel is served on every boot, showing calm state with no peers on a
/// single-node server.

/// Operator deploy surface authorization.

/// Shared server state construction and access.

pub mod stream;
/// Umask-independent temporary directories for tests that exercise
/// private-root validation.
