sloop-daemon 0.5.0

//! Compiled-in authoring templates for the files operators write by hand.
//!
//! Users install Sloop as a bare binary, so nothing in this repository —
//! including `docs/` — is reachable from an installed `sloop`. These
//! templates are the grammar documentation that ships with the binary:
//! `sloop template <kind>` prints one to stdout, and the intended use is
//! redirection (`sloop template ticket > .agents/sloop/tickets/mine.md`).
//! Writing into `.agents/sloop/` directly is deliberately not offered: the
//! ticket directory is a live queue, so an example file dropped there is an
//! example file at risk of being posted.
//!
//! Every template is a working example annotated with comments, and the
//! tests below round-trip each one through the same parser the daemon uses.
//! A grammar change that these templates do not follow fails the build
//! rather than shipping documentation that lies.
