Place in the proof route

The chapter uses this material in the route toward The augmentation preserves the desired target as a marginal. The declaration-level source map is intentionally left inside the formalization layer until exact theorem anchors have been audited.

Why is this valid?

Chapter-level validity conditions

  • Both conditional distributions require finite, measurable normalizing constants.
  • Marginal preservation follows from Tonelli/Fubini only after nonnegativity and measurability are established.
  • An oracle specification must state whether samples are exact or approximate.
