Thread a derived named view of a sweep point so consumers stop re-zipping param_space() names onto the bare &[Scalar]. A free function zip_params over (ParamSpec names ⊗ positional point) in aura-core; GridSpace retains the ParamSpec list it already receives in new(); SweepFamily carries it and exposes named_params(i). The run-closure signature `F: Fn(&[Scalar]) -> RunReport + Sync` stays byte-for-byte (honours #52's #71-firewall constraint, so RandomSpace plugs in with zero reconciliation). The lossy f64 collapse moves into the manifest constructor; the view stays typed. Behaviour-preserving; SweepPoint and enumeration untouched. Design ratified in-context (brainstorm, approach C over A, free function over a NamedPoint type); a reconciliation comment on #57 records the resolved forks with provenance. Human sign-off after the auto-sign panel's grounding lens caught a blast-radius undercount in the first draft — corrected to all eight sim_optimal_manifest call sites plus the aura-registry SweepFamily struct-literal. refs #57
