Role-based handoff: define where technical artist will be used and what stakeholder signoff must prove there.
Preserve the untouched technical artist asset and record tested artifact before changing geometry, materials, textures, hierarchy, or metadata for stakeholder signoff.
For technical artist stakeholder signoff, Keep the brief, before-and-after asset, acceptance note, next owner, and due decision. Product, marketplace, regional, and compliance decisions still require the responsible specialist.
