Free knowledge does not mean a lower standard.
Core House of Kacinari content is publicly available without charge. Claims are separated from opinion, time-sensitive information has a currentness status, and sources and evidence remain part of the publication system.
Professional diplomas, laboratory reports, and institutional qualifications have a separate role. House of Kacinari does not replace them.
LIVING REFERENCE
Facts have context and a date.
Stable
Foundational knowledge that rarely changes.
Monitored
Areas that are periodically rechecked.
Time-sensitive
Market, regulatory, or industry information where the date is part of the meaning.
Critical currentness
Information that should be rechecked immediately before a practical decision.
WHAT’S NEXT
Next phase: the Visual Atlas.
After the clean build, the focus moves to verified images, usage rights, attribution, provenance, and connecting visuals to the existing diamond content.
IN DEVELOPMENTVisual AtlasIt will be populated only with visuals for which source, rights or permission, credit, and context have been verified.
