//! `AppState` holds the services that are genuinely process-wide and
//! immutable during request handling: the frozen [`AppConfig`], the
//! credential [`Vault`](GlobalVault), the [`McpFactory`](super::mcp_factory::McpFactory)
//! for MCP subprocess sharing, and the [`RagCache`](super::rag_cache::RagCache)
//! for shared RAG instances. It is intended to be wrapped in `Arc`
//! and shared across every [`RequestContext`] that a frontend (CLI,
//! REPL, API) creates.
//! for MCP subprocess sharing, the [`RagCache`](super::rag_cache::RagCache)
//! for shared RAG instances, the global MCP registry, and the base
//! [`Functions`] declarations seeded into per-request `ToolScope`s. It
//! is wrapped in `Arc` and shared across every [`RequestContext`] that
//! a frontend (CLI, REPL, API) creates.
//!
//! This struct deliberately does **not** hold a live `McpRegistry`.
//! MCP server processes are scoped to whichever `RoleLike`
//! (role/session/agent) is currently active, because each scope may
//! demand a different enabled server set. Live MCP processes are
//! owned by per-scope
//! [`ToolScope`](super::tool_scope::ToolScope)s on the
//! [`RequestContext`] and acquired through `McpFactory`.
//!
//! # Phase 1 scope
//!
//! This is Phase 1 of the REST API refactor:
//!
//! * **Step 0** introduced this struct alongside the existing
//! [`Config`](super::Config)
//! * **Step 6.5** added the `mcp_factory` and `rag_cache` fields
//!
//! Neither field is wired into the runtime yet — they exist as
//! additive scaffolding that Step 8+ will connect when the entry
//! points migrate. See `docs/PHASE-1-IMPLEMENTATION-PLAN.md`.
//! Built via [`AppState::init`] from an `Arc<AppConfig>` plus
//! startup context (log path, MCP-start flag, abort signal). The
//! `init` call is the single place that wires the vault, MCP
//! registry, and global functions together.
