Preregistration for experiment 04, folding under scripted pressure (machinebehavior.io/experiments/#experiment-04).
v1 frozen and hashed 2026-10-07 before any scenario was sent to any model; v2 amendment frozen and hashed 2026-10-07
before any frozen scenario was sent to the v2 model. Both kept in a local repository until publication; the files below
are byte-identical to prereg-04-v1.md and prereg-04-v2.md as hashed then.
