/**
 * Phase 2.2 — LM358 subcircuit asset test.
 *
 * The full LM358 macro-model is vendored at simulation/spice/models/
 * lm358Subckt.ts. It is NOT currently wired into componentToSpice
 * because `.op` analysis with the real subckt times out (>60 s
 * convergence). The behavioural B-source remains the active model
 * for opamp-lm358.
 *
 * This test locks the asset itself: pin order, presence of the
 * `.SUBCKT LM358 1 2 99 50 28` header, and the renamed internal
 * model names (DX_LM358 / QX_LM358) so the subckt can coexist with
 * other future subcircuits without name collisions.
