//! Typed error boundary for the runtime crate.
//!
//! All public APIs of `systemprompt-runtime` return [`RuntimeResult<T>`]
//! (i.e. `Result<T, RuntimeError>`). [`RuntimeError`] composes the typed
//! errors of upstream layers (config, database, events, files, users,
//! extensions) via `#[from]` so callers can pattern-match on the original
//! cause without losing fidelity.
//!
//! Calls into upstream crates that still return `anyhow::Result` (for
//! example schema/seed installation and database connectivity probes)
//! are stringified into the [`RuntimeError::Internal`] variant at the
//! call site so the lossy conversion is visible.
