1//! Core library for orchestratectl.
2//!
3//! See `issues/orchestratectl-mvp/design.md` for the canonical schema and
4//! protocol references. This crate provides:
5//!
6//! - The on-disk schema types ([`Manifest`], [`Node`], [`Event`]).
7//! - Atomic write helpers ([`atomic`]) and per-run advisory `flock`
8//!   ([`RunLock`]).
9//! - The canonical mutation entry point
10//!   ([`append_and_apply_event`]): append one
11//!   event and fold it into the projections under the run's `flock`.
12//!
13//! Higher-level supervisor and CLI logic live in their own crates / issues.
14//!
15//! `octl-core` is the canonical library surface, so public items are required
16//! to carry doc comments (`#![warn(missing_docs)]`). Lint-level policy
17//! otherwise lives in the workspace `[workspace.lints]` table (pedantic clippy).
