TL;DR of the paper, generated automatically.

A replayable portrait studio that rebuilds drawings from a stored file, with no model call on replay.

• Setup: a sitter picks one of eight fictional artists, then a hosted image model makes a private study.
• Replay: a compiler turns the study into one drawing document, so the same portrait comes back each time.
• Bias bug: the earlier compiler read dark skin as paper and kept less of those faces (13 to 48 percent against 41 to 56).
• Still open: only two generated test sitters, and no real-face study yet.
