Functions
bool	line::error_detail::valid_kind (const std::string &s)
	True when s matches [A-Za-z][A-Za-z0-9_]*, the grammar of a kind.
std::string	line::error_detail::make_id (const char *category, const std::string &kind)
	LINE:<category>:<kind>, or LINE:internal:BadErrorId for a malformed kind.

Detailed Description

The exception types the port throws.

Error and its five refinements, one per category of the cross-codebase error vocabulary (_kb/17-error-vocabulary.md): InputError for a malformed model or argument, NumericError for a computation that cannot produce an answer, UnsupportedError for a feature the chosen algorithm does not cover, ExternalError for a missing or failed tool, and InternalError for a bug. Nothing in the library calls exit() or writes to stderr on failure: the CLI catches these at main and the bindings map them to exceptions, so the same code path serves both.
