The three factor branches
The finite branch records only the fixed trace, matrix presentation, and local published inputs used in the preceding application. The alternatives are the structural factor classification; no alternative assumes an operator estimate.

OAI.KadisonSimilarity.PublishedFactorCasesInputline 104Source documentation
Precisely the factor alternatives needed downstream. The finite model is supplied by Popa's increasing-matrix subfactor theorem and the listed local inputs; the other two alternatives are projection/type classification.
