Module cbor 

uor_addr::cbor — the CBOR realization of UOR-ADDR (ARCHITECTURE.md “Format-specific realizations”).

CBOR typed-input content-addressing under RFC 8949 §4.2 Deterministic Encoding, with the σ-projection bound to prism::crypto::Sha256Hasher by default and the other 32-byte axes (crate::hash) available via the address_<algorithm> entry points.

Authoritative sources

• CBOR + deterministic encoding — IETF RFC 8949 Concise Binary Object Representation (CBOR), §4.2 Deterministically Encoded CBOR (https://www.rfc-editor.org/rfc/rfc8949). The canonical-form invariants — preferred (shortest) integer/float encoding (§4.1, §4.2.2), definite-length items, and bytewise-sorted map keys (§4.2.1) — are validated against RFC 8949 Appendix A’s diagnostic ⇄ encoding vectors in tests/cbor_rfc8949.rs.
• SHA-256 σ-projection — NIST FIPS 180-4.

End-to-end (ADR-060)

1. canonicalize re-encodes any well-formed CBOR item into its RFC 8949 §4.2 deterministic form into an alloc buffer.
2. address wraps those bytes in the borrowed CborCarrier and runs AddressModel’s forward(): the ψ-chain verb threads the carrier through the shared AddressResolverTuple (ADR-036), and ψ₉ folds the canonical bytes through the σ-axis in one σ-projection.
3. address returns the crate::AddressOutcome carrying the κ-label + replayable TC-05 witness.

Modules

model

cbor::AddressModel* — the cbor realization’s PrismModel declarations, one per admissible σ-axis (crate::hash). Each binds the shared AddressResolverTuple ψ-tower and the axis’s capacity profile (AddrBounds for the 32-byte axes, AddrBounds64 for sha512). AddressModel (sha256) is the default.

pipeline

cbor::address* — the CBOR realization’s public entry points, one per admissible σ-axis (crate::hash).

shapes

Substitution-axis selections for the CBOR realization.

value

CBOR typed input (ADR-023 amended by ADR-060) with RFC 8949 §4.2 Deterministic-Encoding canonical-form byte output.

verbs

CBOR realization’s ψ-chain content-address derivation verbs (wiki ADR-024 + ADR-035 + ADR-036), one per admissible σ-axis.

Structs

Sha256Hasher

Default Hasher<32> selection for the CBOR address-derivation pipeline. FIPS-180-4 SHA-256 hasher. 32-byte digest.
