Iteration-1 §A of the construction service (#157): the surface-agnostic shared
predicates the eager op-script path and the holistic finalize gates both call —
no second validator (C24).
- edge_kind_check (blueprint.rs): the per-edge producer/consumer kind check,
lifted verbatim out of validate_wiring's edge loop into a pub(crate) fn that
validate_wiring now calls — behaviour-preserving (same Bootstrap(KindMismatch)
variant; the existing compile-time gate test stays green).
- resolve_input_slot / resolve_output_field (builder.rs): the exactly-one-match
name→index resolution extracted as pub(crate) fns over (&NodeSchema, &str), so
the runtime-String op-script names share GraphBuilder's resolution; GraphBuilder
delegates and maps to the unchanged BuildError variants.
- try_bind + BindOpError (aura-core node.rs): the fallible Result twin of bind
(bind keeps its panic contract and pinned messages verbatim; try_bind is a
separate method reporting the same three conditions as values).
- check_param_namespace_injective + validate_wiring widened to pub(crate) for the
finalize-stage reuse by the upcoming GraphSession::finish (§B).
Partial iteration: §B (the GraphSession/Op/replay surface + introspection) and
the §A→§B integration land next (plan Tasks 4-8). compile_with_params /
check_ports_connected are behaviourally unchanged. Full suite green; clippy clean.
Plan correction folded in: Task 3's test originally referenced aura_std::Sma —
infeasible inside aura-core (aura-std depends on aura-core; the reverse edge is a
dependency cycle). Adapted to a local PrimitiveBuilder probe with identical
assertions.
