Keep facts, interpretation, unknowns, and volatile commerce separate.
ICU interpretation
Decision guidance from explicit inputs; never rewritten as a source fact.
Unknown / not reported
No zero, average, substitute, or hidden inference is inserted.
Volatile field
Price, availability, lead time, and offer state must be rechecked at the current merchant/source.
DECISION FIRST
Guest and multipurpose sleeping
Compare forms that can switch between guest sleeping, daytime seating, secondary sleeping, or open-floor use.
DECISION CHECKS
Resolve these before shopping by offer
- Define the primary daytime state before comparing forms.
- Check whether a secondary sleeping surface is required.
