/**
 * Slice 8h-GoodsScrub · 7-pillar PC scrub on a CONFIRMED Client PO · end-to-end.
 *
 *  1) Seed a fresh goods project + walk it through 8g CRM onboarding to CONFIRMED PO.
 *  2) getOrCreateDraft — creates scrub + auto-seeds MATERIALS from PO items.
 *  3) Idempotency — second call returns same scrub.
 *  4) addLine × each of 7 pillars.
 *  5) recomputeTotals math correct per pillar + grand.
 *  6) setMaterialsUnitCost enriches seeded line + updates total.
 *  7) Guards: unknown pillar refused; unit_cost < 0 refused.
 *  8) markComplete refuses when MATERIALS line has unit_cost=0.
 *  9) After fixing, markComplete succeeds → status flips to COMPLETE.
 * 10) After COMPLETE, further addLine + removeLine refuse (locked).
 * 11) Wiring surface: workspace exposes scrub link when PO CONFIRMED + perms + view + controller.
