blind sculptor
Reveal evidence to a model one measurement at a time and let its assumptions become a constrained SDF sculpture before the source is finally shown.
surface
The model begins with almost no evidence about a hidden source.
disturbance
The visitor chooses which edge, depth slice, color patch, motion cue, or word to reveal next; the model must commit to bounded geometry after each disclosure.
recognition
Every confident form contains assumptions about what the missing evidence probably is. More evidence does not merely add detail; it can force topology to change.
system
Schema-constrained SDF grammar, incremental evidence packets, model revision history, local renderer, and a final side-by-side source reveal.
