Statement
Under Assumption 4.1 and the canonical Hilbert carriers inherited from the basic construction, every nonempty finite witness window has bounded multiplication with . The total source without multiplication demand is admissible; requiring its induced multiplication to be closable makes the total context inadmissible. The full-core face has maximal graph defect.
Meaning and scope
This is the explicit directed rectangular obstruction. The chosen canonical completion is essential to the statement.
