A leaf primitive built with `.named("fast")` now renders its `aura graph` viewer
box head as `fast: SMA[length]` — the instance name as a `:` declaration prefix.
An unnamed leaf keeps the bare `SMA[length]`.
Engine half: a new raw `PrimitiveBuilder::instance_name() -> Option<&str>` (the
explicit name, default not resolved) feeds a conditional leading `"name"` field
in prim_record, present only for an explicitly-named node; both golden twins
(inline model_golden + sample-model.json) re-captured. Viewer half: adaptNodes
carries `name`, the genDot leaf-emit forwards it, and cellLabel prepends the
`name: ` prefix when present (composites stay bare). `named()`'s non-empty
debug_assert is unchanged, its doc re-grounded to the now load-bearing Some/None
invariant (knob-address segment + prefix switch).
The name is a render/model-only debug symbol — dropped at lowering (C23), and the
model stays deterministic (C14). Parameter ganging (one knob, several nodes) was
considered and spun off as an explicit composite-shared-param idea (#61), not via
name collision (param_space is injective, C12/C19).

//! Integration guard: the `aura graph` viewer renders an explicit instance name
|
|
//! as a `name: ` prefix ahead of the type head, and leaves an unnamed leaf bare.
|
|
//!
|
|
//! Like `viewer_dot.rs`, the property lives in JavaScript (`cellLabel` in
|
|
//! assets/graph-viewer.js), so this shells out to `node` running the headless
|
|
//! guard `tests/viewer_name_prefix.mjs`, which loads the real viewer module and
|
|
//! drives the exported `genDot` over a minimal model (a named SMA + an unnamed
|
|
//! Sub).
|
|
//!
|
|
//! `node` is REQUIRED: if it is not on PATH this test FAILS (a skipped guard is
|
|
//! not a guard).
