Not every discussion is automatically canon. Use these classes:
Explicitly confirmed by the creator or designated authoritative. Document as fact.
Current working assumption, not final. Mark as provisional.
Ideas not yet accepted. Keep as proposals; do not silently merge into established canon.
Identified but unresolved, incomplete, or intentionally ambiguous.
Formerly established, later revised. Preserve history; mark which version is current.
Creator has final authority. Flag contradictions rather than inventing certainty.
