Recognition Science chemistry derives five major organic functional groups from the configuration dimension. The definition packages this count into a certified structure for use in downstream derivations. It is realized by a direct assignment from the decidable cardinality result.

claimLet $FG$ denote the finite type of canonical organic functional groups. The definition constructs a certificate $C$ of type $FG Cert$ by setting the field asserting $|FG| = 5$ to the value supplied by the explicit cardinality theorem.

background

In the module on organic functional groups from configDim, five canonical classes are identified corresponding to configuration dimension D = 5: hydroxyl (alcohols/phenols), carbonyl (aldehyde/ketone), carboxyl (acids/esters), amino (amine/amide), and thiol/sulfide. This setup derives from the Recognition Science approach linking molecular features to the underlying configuration space. The upstream result is the theorem establishing that the cardinality of the FunctionalGroup type is exactly 5, proved by decision procedure. The structure FunctionalGroupsCert is defined to hold precisely this cardinality assertion as its sole field.

proof idea

The definition is a one-line record constructor that directly assigns the result of the functionalGroup_count theorem to the five_groups field of the FunctionalGroupsCert structure.

why it matters in Recognition Science

This definition completes the certification of the five functional groups in the chemistry depth of Recognition Science, directly supporting the module's claim of zero sorry statements. It provides the concrete witness for the configDim-derived count, which may feed into broader derivations of molecular properties from the phi-ladder and forcing chain, though no downstream uses are currently recorded. It aligns with the framework's extension of spatial dimensions to configuration dimensions for chemical classification.
