about

nx_cbor.nx -- RFC 8949 Concise Binary Object Representation, minimal encoder for the substrate's machine-readable wire format. CBOR is the IETF-standard binary JSON-equivalent (RFC 8949). Same information model as JSON, ~30-50% smaller on the wire, deterministic byte-output, zero schema infrastructure. Used by COSE, CoAP, Dapr, and IPLD; chosen here over Parquet/Arrow because: * spans are small + irregularly-shaped (CBOR strength) * we want sovereign-no-deps (one file, pure NishiLang) * the same logical span can ship to JSONL (human) AND CBOR (machine) Spec: RFC 8949 https://www.rfc-editor.org/rfc/rfc8949.html Major types implemented (subset sufficient for spans): 0 unsigned integer 1 negative integer (encoded as -1-value, unsigned) 4 array of N items 5 map of N pairs Major types deferred (queued): 2 byte string 3 text string (UTF-8) 6 tag 7 floats / simple values genealogy_id: bormann_hoffman_2013_cbor + rfc_8949 lineage_id: substrate_native_cbor_v1
