# Authoring diagnostic reference

> Generated static meanings, rules, remediation, evidence limitations, and lifecycle for Registry Stack project-authoring diagnostics.

import DiagnosticReference from '../../../../components/DiagnosticReference.astro';

Use this catalog when `registryctl check` rejects authored project structure, syntax, or
cross-file semantics. Diagnostic output can add a safe file address or received type class, but
the stable meaning, rule, and remediation below come from the same closed authoring definitions
that own each code.

Run `registryctl project diagnostics --catalog authoring --format json` for the exact
workspace-independent machine catalog. A valid catalog command exits zero and writes only the
selected format to standard output. Invalid CLI arguments exit with Clap's usage status. A
fail-closed catalog invariant error exits nonzero without reading project or runtime state.
