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.
