Coarse-graining support: Support.Book.Ch05.Theorems.Section57.UniformHighBottom #

Imported from the Apache-2.0 CoarseGraining development at commit c7ddd76c08ade64fed1b8d2ca51be14dfee8deb4.

The mixed high-bottom branch at the uniform endpoint #

The endpoint high-bottom branch keeps the localized Γ_2 concentration mechanism and adds the deterministic Γ_∞ crude cutoff. The final row collapse is built on these two separate inputs.

The localized high estimate in the high-bottom branch, specialized to the uniform endpoint by forgetting Γ_∞ to finite Γ_2.

The deterministic crude cutoff in the high-bottom branch. If the crude tail parameter is at least one, the bad-pair event, hence the high-bottom subevent, has zero probability.

Convert a one-branch softened fixed-pair estimate into the weighted row shape used by the endpoint bottom summation.

Endpoint high-bottom deterministic tail-parameter comparison.

When the crude cutoff has not fired, the crude denominator pays for the missing high-branch factor 3 ^ ((d - 2t) * (q - n)).

Endpoint high-bottom fixed row estimate. The only side condition is the explicit domination of the high denominator and the crude cutoff denominator by the selected endpoint denominator.
