Module resource_catalog 

Resource Catalog — canonical types, Quin encoding, and CapabilityProfile binding.

This module defines the authoritative Rust types for the YAML-backed resource catalog (resources/*.yaml). It is the single source of truth — the Flutter bridge and CLI both reference these types, not their own copies.

Quin encoding

Each catalog entry can be encoded as a set of NQuins for first-class graph membership. Predicate convention:

Predicate string	Meaning
llm:hasFormat	Model file format (e.g. gguf)
llm:hasQuantization	Quantization level
llm:hasSizeMb	File size (inline integer)
llm:hasRamEstimateMb	Peak RAM needed (inline int)
llm:hasSourceRepo	Source repo hash
llm:hasLicense	License identifier hash
ont:hasFormat	Ontology serialisation format
ont:hasDomain	Domain tag hash
prov:wasGeneratedBy	Provenance: download event
prov:atPath	Local file path hash
prov:atTimestamp	Unix timestamp (inline int)
