This is one of the load-bearing sentences of the program. It is a statement about one individual on a time-slice, not about an ensemble, and not about the present quantum state vector. The complete description is written with a cut the laboratory can actually make. Shields 2026a, §4.
This analog, written out
Scoarse = ( a=1, b=-0.85, m=1, κ=1.15, {Ak, ωk}, qexit=1.35, q0=0.02, p0=0 )
S⊥ = ( θ1, …, θ8 ) ∈ [0, 2π)8
Same well, different θ, different crest, different first-exit time. The laboratory that prepares the well and does not control phases is doing statistical mechanics of an unread remainder, not discovering chance in the ODE. Course, lessons 00–01.
