Pressure, Not Costume

Anvil's eleven modes are not dramatic labels over one “ask many and pick” loop. Each mode changes the artifact graph, what participants may see, which intermediate work is required, and what the bench ultimately judges.

Arena pressures independent alternatives. Relay pressures successive improvement while protecting every checkpoint. Elimination pressures survival under full bench feedback. Workshop pressures critique and revision without cuts. Debate pressures assigned positions toward a conclusion. Red Team pressures artifacts through attack and defense.

Synthesis pressures recombination to beat the best single entry. Party tests author-chosen review against solo controls. Apprentice tests assigned pre-draft guidance. Defense tests artifacts through common examination. Restoration requires a scored diagnosis before repair in one seat turn.

Choose the mode by the weakness the workpiece must expose, then preserve that mode's exact roles, phases, caps, and judged surface. If the implementation changes those, it has changed the experiment.

Mode is the pressure graph. The name matters only because it binds a precise operational contract.
