Inspect a Registered Engine Specification

Returns a read-only description of a registered engine, including its normalized capabilities, source ("builtin" vs "plugin"), aliases, and dispatch strategy. This is intended for extension authors and diagnostic tooling; it does not expose the underlying fit/preflight functions.

Usage

engine_spec(name)

Arguments

name

Engine name, such as "rrr_gls" or "latent_sketch".

Value

A list of class fmrireg_engine_spec, or NULL if the engine is not registered.
