Module variant 

uor_addr::variant — UOR-ADDR’s cost-model-bearing variants (ARCHITECTURE.md “Cost-model-bearing variants”).

Every variant in this module specializes one of UOR-ADDR’s format-specific realizations (typically crate::json) by binding a non-default C: TypedCommitment at the PrismModel declaration. The κ-derivation itself is unchanged; the C selection adds typed-bandwidth admission predicates per ADR-048’s cost-model surface plus QS-06’s exemplar shape.

Architectural commitment: UOR-ADDR’s surface admits any C: TypedCommitment parameterization through the same PrismModel declaration form. The variants in this module demonstrate the parameterization through concrete realizations.

Shipped variants

• storage — content-addressed-storage variant binding C = AndCommitment<EmptyCommitment, SingletonCommitment<LexicographicLessEqThreshold>>. The κ-label’s emission carries a typed-bandwidth admission of the κ-label into the storage tier (the threshold selects which κ-labels admit to the cost-bearing tier).
• signed — signature-required-on-emission variant binding C = SingletonCommitment<UltrametricCloseTo<2>>. The published UltrametricCloseTo predicate admits κ-labels whose σ-projection digest is ultrametrically close (2-adic-prefix-aligned) to the signature reference — the byte-shape property an ADR-049 axis::cryptanalyze signature witness validates.
