cratefield-cli 0.6.1

//! The catalogue of every `fz` error code: stable kebab-case slugs an
//! agent can branch on forever, the seed of the MCP server's "stable
//! error-code catalogue" (issue #160). Modelled on
//! `cratefield_core::problems`: a struct of `&'static` definitions, a
//! registry function, stable string codes. Seeded by `fz doctor` (#220);
//! the agent-safe workflow commands (`fz plan` / `deploy` / `add` /
//! `init` / `verify`, harness #140) appended theirs.
//!
//! The contract: a code is never renamed, reworded or removed. A failure
//! *message* may change wording freely; a *code* may not. New codes append.

/// Definition of one `fz` error code.
