IA: DTF film OOS — human size alternatives; Ephraim on CC Dr Zaid ordered 600mm DTF film; Mulanga: OOS, only 300mm available, no ETA for 600mm. Client asked if 300mm works on H-DTF / third-party rolls. Ephraim/sc@ auto-reply appeared later on thread — human must confirm machine width compatibility; do not invent ETA. Rule: On consumable OOS, state available alternate widths clearly; never promise arrival without ETA; override Ephraim if it guesses fitment.
