//! Module: workflow::bootstrap::nonroot

//! Responsibility: run asynchronous local bootstrap work for non-root canisters.
//! Does not own: topology creation, self-registration, or cross-canister orchestration.
//! Boundary: lifecycle schedules this after synchronous runtime initialization succeeds.

/// Bootstrap workflow for non-root canisters during init.

/// This function is scheduled asynchronously after the IC `init` hook
/// returns and after runtime initialization has completed.
///
/// At this point:
/// - Environment identity is fully initialized.
/// - Stable memory invariants hold.
/// - The canister is safe to run asynchronous tasks.
///
/// Failures in this phase are non-fatal:
/// - Errors are propagated to the lifecycle adapter.
/// - The adapter logs failures but does not abort canister initialization.
///
/// `_args` are opaque, user-provided bootstrap arguments forwarded from init.
/// They are currently unused.
///
/// This function is safe to retry and safe to run multiple times.
