# Demo unit swap blocked by white DTF powder stock gap (CPT)

KM4213-CHANTE-98: fetch demo H-DTF/OVEN/A3 + hand new unit + powder. CPT had only black powder; white powder wait delayed swap months; client agreed to wait; Jan 2026 chase still open.

Lesson: check consumable stock (powder colour) before promising demo-return swap date; send powder with tech when available.
