PortSpec gains a non-load-bearing `name: String`, so an input port is named just as FieldSpec.name (output) and ParamSpec.name (param) already are — input ports were the lone unnamed member of the node signature. Identity stays positional by slot (C23); the name is render/debug only, never read by bootstrap or the run loop. PortSpec drops Copy (String is not Copy), exactly as ParamSpec already does. - Every aura-std node names its input slots: SMA/EMA "series", Sub/Add "lhs"/"rhs", Exposure "signal", SimBroker "exposure"/"price" (the slots become self-documenting), LinComb "term[i]" and Recorder "col[i]" generated in their build loops (mirroring LinComb's existing weights[i] param loop). - derive_signature carries a composite's Role.name into the derived input port (it was dropped before — the output side already carried FieldSpec.name), so the graph model is homogeneously named at both levels. - model_to_json (port_json + the composite-header inputs in scope_json) emits the name as a third tuple element: ["f64","any","exposure"]. The byte golden was re-captured (machine bytes) and its substring twins updated; the model is now fully named across inputs/outputs/params. - All 16 PortSpec construction sites threaded in one compile-gate change; test fixtures carry fixture names. C8 realization note added to the design ledger. Why name-only, no validation: the name is a pure debug symbol. Wire-by-name was rejected (it would be a C23 contract change). Bootstrap slot-wiring validation (which would close #21's same-kind swap footgun) is deferred to its own cycle — a name alone does not catch the swap; it makes the slots self-documenting and gives a future validation something to check against. Verified: cargo test --workspace 168 green; clippy --all-targets -D warnings clean; cargo build --workspace clean. Read-only render path (C9), no serde (C14), scalar kinds unchanged (C4). closes #50 refs #21 refs #51
